1962 Dyer Dhow "Midget" Dinghy

A New Dinghy Project - 1962 Dyer Dhow "Midget" Dinghy

I had a Dyer Midget before but it was missing all the sailing bits.  It was a 1981 model that was confirmed by Dyer themselves (www.theanchorage.com).  However, after seeing how expensive the sailing components would be to source, I decided to sell it at the end of the 2016 season and to focus on finding one that was more complete.

This past summer, I found one in Marblehead, MA on Craigslist and decided it was a good boat project to tackle.  The total cost was $400.  It included the boat, as well as the sailing pieces (rudder, centerboard, boom, and both mast parts.  The varnish on the spars was worn and will need to be refreshed, but they were all there.  The boat itself was another story.

All of the white oak gunwales were shot.  In fact, they had been replaced at some point already but not properly attached (glued instead of using the factory copper rivets).  They would need to be replaced.  The keel (white oak) was also shot and needed replacement as was the transom (mahogany).  The seats (or thwarts) were solid (mahogany) but were covered with many layers of paint.  The fiberglass hull was in good shape, but painted poorly inside and out.

This is the way she appeared when I got her home.



Tear Down / Research on Origins

The strip down process was sort of a pain, especially since a prior owner, while using oak, laminated many thin strips to form replacement gunwales and glued them down instead of riveting them.  I am replacing them with a factory kit from The Anchorage.  They are extremely helpful on the phone with answering questions and providing restoration parts.

I stripped off all the old hardware (Oar locks), lifting eyes, rudder hardware and bagged and labeled each with their respective screws and bolts.  The seats (thwarts) were also removed.  The rotted skeg was removed too.  All parts were kept in case we needed to use them for a pattern.  Most of the bronze screws and bolts are stripped so I am going to replace them all with new.

The transom was apparently just glued down.  It took some careful prodding, but I did get it off using a wedge and gentle tapping.



 In removing the transom, I had stripped paint off in the hope of finding a serial number, and I did!  It is 2229SH.  The "SH" is for "High Sheer", and an email to the Anchorage told me that my boat was built in 1962 and originally sold to a dealership in Maine.  I also googled the patent number and found some nice documentation on the US Patent Office web site on the original design from 1947.



Hull Repair

The hull was in very good shape, except one spot under the stripped-away gunwale, where it looked like a chuck got torn out.  I refer to it as its "shark bite".  This cleaned up quickly with some Westsystem epoxy and fiberclass cloth.  It will for the most part be hidden from view anyway by the new gunwales.



Centerboard Trunk Repair

The later Dyer Dhow Midget dinghies have a fiberglass centerboard trunk.  Mine, being from 1962, is much earlier than that and had a wooden one made from what appears to be mahogany.  The upper 2 inches of it were rotted.  I was originally thinking of ripping it out and building a new one, but the bottom 12" was just fine.  So I bought a scrap of mahogany from Highland Hardwoods in Brentwood, NH to make the repair.  

I cut 2" down (actually about 1.9") and sanded the rest flush.  The pieces were glued in place with waterproof wood glue.  As you will see later, the whole trunk was primed with Interlux primer and later painted with the interior with Interlux bilge paint.  

One think I will need to do is locate the hole for the pin that locks the centerboard down.  Not sure how I'll do that yet but I will figure out something.






Painting the Interior of the Hull

The Dyer Dhow dinghies are usually shipped with the interior "raw", meaning that it just has a dull yellow color of the original fiberglass.  While I prefer this look, it could delaminate after decades of UV exposure.  A prior owner of mine took the liberty of painting this with a tan paint.  It was flaking off and needed to be fixed.  My first thought was to use chemical stripper.  What a sloppy mess.  I gave up on that idea.  Next I was going to heat strip it off, but my heat gun was probably going to cause the fiberglass to weaken so I gave up on that idea too.  I finally just used a sander with some 80 grit disks, and cleaned up the inside of any flakes.  I scrubbed it down with warm soapy water and rinsed it with clear water.  I dried it and then gave it a final prep with acetone-soaked rags.


I first applied Interlux primer.  After a few days of drying, I applied two coats of Interlux bilge paint, with a wet sanding with 400 grit sandpaper in between.  I was very happy with the results.  This paint is super hard.  It is designed to repel all the spooge that gets into the bilge of a boat.  If I ever need to touch it up in the future, I'll just wet sand the spot and apply another coat.  

I did use a roll and tip method and that did smooth it out nicely.  





Transom Replacement

Using the old transom to get angles, etc. I made a new transom out of another piece of mahogany that I purchased from Highland Hardwoods.  I had a friend with a wood shop thickness-plane it down to 1" thick and 6" wide to match the original.  However, not wanting to trash a perfectly good piece of wood, I first made one first out of a piece of 5/4 pressure treated decking I had laying around to get the fit.  I then cut the mahogany board down to size and did a lot of sanding to get it to fit snugly.  

The rear of it that will be against the fiberglass was coated with Petit wood sealer.  The parts that are exposed were painted with 4 coats of Epifanes varnish.  Each coat was left for a few days to dry, then wet sanded with 400 grit paper and cleaned with mineral spirits before the next coat.


The board was then cross-hatched with 3M 4200 Marine Sealant to glue it down, then clamped in place.  



Building a new sail

As many of my friend know, I love to sew.  I have a Sailrite LSZ-1 and an old Singer 251 industrial machine that I use for my side business The Windward Rail.  Rather than buy a sail already made from Dyer, I ordered a kit from Sailrite.  Their sailmaker, Jeff Frank was very helpful and responsive.  The kit was very easy to assemble especially when I took over the dining room table for the larger assembly steps.  I even made my own Dyer Dhow class logo out of insignia cloth.  

I debated whether to put the boat's hull number on the sail (#2229) but that would be overkill.  I can always add that later along with some draft stripes.  





Gunwale Replacement

The gunwale replacements are available as a kit directly from Dyer.  They include 5 pieces of oak, along with a bag full of copper nails, washers and a few other items (screws, longer nails).  The 5 pieces of oak include the inner "clamp" (3 pieces), and the outer "guard" (2 pieces).

The front inner clamp was the first piece to install.  The directions provided by Dyer were good, but glossed over some important details, like the amount of time and labor it would take to get this piece to fit.  I would clamp it in place, mark where to sand, then unclamp it, sand some, and do it all over again.  I bet it took 25 iterations over a week before I got it to the point where I was satisfied.  

Using the original holes, I drilled through the inner clamps.  Then after I clamped on the outer guard, I drilled through from the inside and installed the rivets.

Each rivet consists of a copper nail inserted from the outside.  A copper washer is placed over it, the nail is trimmed to about 1/8", and then you peen it flat to make a rivet.  While hammering, I used a heavy piece of steel from the outside as an anvil.  

The fitting was a pain, but the riveting was quite fun.








While I did mark where the oarlocks and seats would mount, I had actually placed two rivets in hole where the oarlocks would have to go, so I had to remove them.  This was accomplished by using a dremel tool to take off the peened washer, and then banging the nail carefully out with a hammer and a steel finishing nail.


Boom repair

The oak boom guides (not sure what these should be called) were rotted pretty badly, but the rest of the boom is fine.  It will just need some light sanding and varnishing.  Dyer sells a kit to repair this, which includes the two wood pieces, a brass nail, and two washers.  

The two screws are removed, and the old nail was cut and the rotted pieces came right off.  Installing the new one was essentially reversing the process.  The bronze fitting with the hook and eye pivots on the brass nail.  I installed the washer on the nail, snipped it to size, and peened the other end to rivet it in place.  

I was able to reuse the screws that I took out, which was helpful because the kit did not come with replacements.  




Spar Bag

I wanted to make a long bag to carry my spars in so they don't bounce around in the truck or in the hull scratching it up or worse, breaking something.  

I had made a boom tent for a friend's O'Day Javelin, and used their old one for a pattern.  They did not want the old one back.  It was a little tattered, but still was good to reuse.  I cut it to size for length, and patched any threadbare holes.  I then folded it over and seamed it, then after turning it right side out, put two long seams lengthwise to create pockets for the spars.

I finished it off with two grommets and some recycled line to tie it together.  

The machine used is my old Singer 241 industrial straight stitch machine.

Everyday Carry (EDC) Backpack Project


Everyday Carry Backpack Project



Ever since I got my Sailrite LSZ-1 sewing machine, I have wanted to try to build my own backpack.  This is the end result.  

I have been watching videos on YouTube, and studying some packs I have for ideas. This will be a small daypack, suitable for carrying a laptop and a few other Everyday Carry (EDC) items. I'm starting to see why a quality USA-made EDC/Day pack costs $200-300.

I'm using 1000d Cordura (Foliage green) for the exterior, and 500d Cordura (Coyote Tan) for the inside lining. I have another pack with the same color scheme that I really like so I'm using it to figure out sizing, etc. It can be seen in the background in some of the photos. 

I traded a friend for the old pack a few years ago. It is not branded so it was probably a prototype, possibly by FirstSpear.  


Most of the supplies were acquired from www.rockywoods.com.  Their service and products have been very good so far.  I will continue to use them for any future projects like this since Sailrite and SailMakerSupply.com do not typically carry Cordura, webbing, etc. in military colors.

This (and most packs) typically have four components.  They are (in the order I built them)


  1. Carry straps
  2. Back panel (the panel that goes against your back)
  3. Side / Bottom panels (mine ended up being a continuous loop)
  4. Front Panel (the panel that is seen by those behind you.  

My intent was to keep the interior spartan but allow it to be customized with MOLLE pouches via PALS webbing.  

The pack does have a frame sheet (1/16" Kydex) in the back panel, along with an ID holder pocket and a document pocket.  The front panel has an internal zipper pocket.  I added PALS webbing inside the front panel and built two zipper pouches that attach to it.  Externally, there are no pockets - only PALS webbing for pouches.  

All told, it took about 20 hours to make this, and cost about $75 in materials.  Considering that I enjoy doing this, my time is free, and I got a really nice pack that would set me back $200 - 300 in return.  Without further ado, here is a summary of the build. 

Step 1:  Templates

I used cardboard and made templates for the straps using another pack that I found to be comfortable.  I also made a template for the back/front panels.  I actually made two because the first one failed to take into account the 1/2" seam allowance around the outside.  I found making both helped.

Step 2:  Back Straps

Using the template, I cut 1/4" Volara foam (closed-cell foam used on automotive tops).  I got a few yards of it on eBay for cheap money.  





I traced the exterior of the straps from 1000d Cordura (leaving the 1/2" seam allowance too).  Remember to make one the mirror image of the other so you don't end up with two left straps.


The interior of the straps is made from "spacer mesh".  It is a foam product used for anything that contacts the body to keep you cool.  Rockywoods had this stuff in Coyote Brown to match nicely with the Foliage Green.  


The two halves are sewn inside out (1/2" seam allowance) leaving the wider end open, then it is turned rightside out (using that broom stick), and the foam is carefully inserted.  Inserting the foam was a pain, but it helped to curve it like a taco shell.  


Here you can see my other pack that I used for sizing, and for the strap pattern.  The spacer mesh matched it exactly.  


Sewing the straps with my Sailrite LSZ-1.  (Yes, the Jack Rackham Jolly Roger sticker was a spare, and fit on the side of the machine ;-)


The completed straps with the foam inserted.  


I sewed 1" webbing down the length of the strap, leaving enough excess at the top and bottom for the lifter straps at the top, and to attach it to the pack at the bottom.  I attached 2" webbing (2 layers) at the top of the strap.  This will be used to attach it to the back panel.  


Step 2:  Back Panel and attaching straps

The back panel has a "base" comprised of 1000d Cordura.  You can see the two layers of the 2" webbing that has been x-stitched to the top of each.  I layed out an angle (just sort of winged this based on other packs) and sewed them in.  I then put a horizontal piece of 2" webbing across them and sewed that down and trimmed off the bottom of the 2" webbing coming off the straps.  (sorry - wish I took more pictures of this)



Below the 2" horizontal webbing, I attached another 1/4" piece of Volara Closed-cell foam, and a piece of spacer mesh, and sewed it down making channels.  The pattern really does not matter.  



Step 3:  More back panel work

I ordered a piece of 12" x 24" 1/4" Kydex on eBay to make the back panel.  I used the smaller cardboard template to trace it, and cut it with sheet metal shears.  I sanded the edges to remove any burrs that could tear the cloth later.  This had to be sized when I installed it into the final pack some more later.  



The inside of the back panel is made from 500d Cordura (Coyote Brown).  I put a piece of 1" Velcro to form a pocket for the frame sheet.  


To this, I made a little ID holder, and put on my custom tags.  I also made another pocket for documents.  I put binding along the top edge of this.  


The inner and out parts of the back panel (with the straps attached to the outer) were held together with paper clips, then sewn together with a 1/2" seam.    




This was a great milestone because now I could actually try it on for size, and it is starting to look like a real backpack.  


Step 4:  Side Panels

This step involved some careful measurements for determining where to position the zipper on the pack, and to build in a "storm flap" in the rear zipper plaque.  I also had to take into account seam allowance, and the overlaps for the zippers.  

For the main zipper, I used a #10 YKK continuous coil zipper and fortunately found Coyote Brown to match the interior liner.  While it does not match the exterior Foliage Green, it goes well with it in my opinion.  

I usually hate sewing zippers.  But, I got a zipper foot for my machine and it makes it a LOT easier.  Why Sailrite does not just give you one with the machine is beyond me.  

The zipper will go completely around the pack and stop about 2" along the bottom so the whole pack can open up like a clam shell.  

The wider rearward zipper plaque was cut to 9" to allow 7 1/2" of exposure, with seam and zipper allowances.  The narrower forward zipper plaque was 2" including seam allowance.  I carefully measured the distance around the circumference of the pack to have it be 43 1/2" when assembled.  It actually worked.  Measure twice, cut once.

I would eventually cut off the ugly noisy metal zipper pulls and replace them with parachute cord (12" lengths) with an overhand knot and shrink tubing.  Very tactical looking ;-)



Now, I need to add the carry handle and the triglides for the lifter straps.  The carry handle is 2" webbing, with a 1" piece sewn over it.  This is all x-stitched in place.   I wish I made the 2" strap a little narrower to fit my hand.  I discovered this after using the pack for a week for work.  



Next, I decided to over complicate the project and add PALS webbing to the sides - 6 rows with 4 channels each.  These look great, add strength to the pack, and allow the user to add external pouches as required for the mission.  My machine is not very good at bar tacking so I ended up just doing 3 rows of straight stitching for each webbing joint.  




(While technically part of an earlier step, my buckles came in later so I could now finish the carry straps with the nice Coyote Brown ITW Nexus plastic side-release buckles.  



Step 5:  Bottom Panel

I attached the side panel to the back panel to get an accurate measurement of the bottom panel.  To this, I also over complicated it by adding more PALS webbing.  This could come in handy if the user wants to add a small pouch on the bottom of the pack.  The "X" is for a drain grommet.  I do not have any that size but that can easily be added later once I get the right size grommets and tools.    




Step 6:  Assembling Side/Bottom Panels to Back Panel.  

I raided my house for every single binder clip I could find.  I attached both panels together.  Then I stapled them using a common office stapler, and sewed them together with a 1/2" seam allowance.  I went very slowly here, operating the machine by hand to make sure I did not screw it up.  All the planning was time well spent because the sewing it together was easy and anti-climatic.  





Once I was satisfied with the stitching, I put on internal binding to clean it up.  I did NOT use my binding attachment for this...  the material is much too thick for it.  So, I resorted to the binder clips again, which worked fine.  Just sew up to a clip, remove it, and keep sewing until you hit the next clip.  I used a zig-zag stitch for this step (the only ones on the pack) to assure the binding did not miss the material underneath.  


Once this step is complete, I can hook up the lifter straps, and the bottoms of the straps.  





Step 7:  Designing and building the front panel.  

There are multiple layers to this panel.  There is also Velcro internally and externally for patches, etc.  The internal panel has a zipper to create a pouch.  This and the layer behind it are composed of 500d Coyote Brown Cordura.  Above the zipper is a field of Velcro.  I used a #8 YKK zipper here.  



The external part of this panel is 1000d Foliage Green Cordura.  To this was applied yet more PALS webbing (4 rows of 6 channels), and a field of Velcro for Tacti-cool patches.  The inner panel received 2 rows of 6-channel PALS for internal pockets.  




The 3 panels were then assembled with binder clips, staples and eventually sewn.  Then, I realized I missed a critical step and forgot to include points for the compression straps.  It was too late at this point so I had to improvise, and it ended up not being so bad.  More on that later.  




Step 8:  Assembling the Front Panel to the pack.  

More binder clips, more staples, and more sewing.  In the second shot, you can see I am using a regular foot on the machine.  You can see the staples.  Any holes from the staples is hidden by the binding anyway.  This is a very cheap and effective way of temporarily connecting assemblies together for sewing.   



After this was complete, I binded the seam with 1" Coyote Brown binding tape.  I did NOT staple this but used just the clips again.  You can see here how I sew up to the next clip, remove it, and keep sewing.  I did this step cranking the machine by hand to go nice and slow and assure proper stitching.  






Step 9:  Fitting the frame sheet 

The frame sheet did not exactly fit in the back internal pocket designed for it, but I expected that.  I trimmed it carefully with sheet metal shears, and sanded the edges smooth.  Some pack manufacturers will sew binding directly on the frame sheet.  My machine is powerful, but not powerful enough to punch thru a 1/6" piece of Kydex.  




Step 10:  Internal Pockets

I intentionally put in two rows of PALS to I could suspend internal pockets.  My former EDC pack had these and were great for holding my mouse, power cords, keys, etc.  These were assembled out of 500d Cordura, with a #8 YKK continuous-coil zipper.  I made the MOLLE connecting thingies from 1" Velcro strips and scrap webbing.  These were sewn on the back of the pouch at the right distance to align with the PALS (I think 6" apart).    




The zipper pulls were cut off and new ones made from 12" of parachute cord, with an overhand knot, and a piece of electrical shrink tubing to hold them together.  A lighter is used to shrink it.  





The pouches were installed as shown below.  A Velcro-backed Calico Jack Patch was added for effect ;-)





Conclusion

Here you can see the new pack on the right compared to the existing pack I had.  The color is definitely different, but I like it.  The size is nearly identical.  People ask me why did I build one when I already have one?  Because I can (and did!)  

This was a fun project.  I don't think I could ever build these for a business as it is too time consuming.  I would have to mass-produce them to make it cost effective and I simply do not have the time for that.  My next step for this project will be a pouch for the front panel that will be removable.  I'll use the same construction techniques that I used here, with 1000d externally and 500d internally with webbing, Velcro, etc.     



 You can really get a feel for the clam shell opening of the pack with these shots.

Since I forgot to add the points to attach the compression straps, I just connected "repair" clips to the webbing.  The bottom one was long enough that I could just use a spare buckle.
