I am not surprised that the manual stapler cannot drive the composite staples staples into Douglas Fir. I have not used composite staples but have driven many hundreds of thousands of metal staples when I was a professional boatbuilder at the beginning of my carreer. I found hand staplers were only adequate to lightly hold components in position. They were not capable of driving 3/8" (9.5mm) firmly into Douglas Fir. I built a handful of boats with an electric stapler that was capable of driving 3/8" staples but not 9/16" (14mm) staples into Douglas Fir. Pneumatic staplers are capable of driving 9/16" metal staples even into White Oak.

I can no longer source the 9/16" Silicon Bronze staples I used to use and now use Stainless Steel staples for my extracurricular boat building. They are relatively inexpensive compared to the bronze staples I used to use or the new composite staples. I almost always remove them after the glue can hold the components together. But if I break one I just use a nail set to drive the leg below the surface and leave it in place. There are three tricks for removal. 1st, dirive the staple through a sacraficial strip of wood (I usually use popsicle sticks, 150 sticks per USD). 2nd, don't wait until the glue is completely cured. 3rd, use a good staple remover. An added advantage of using the sacraficial strip is that the staple doesn't scar the wood too much.

I attached a photo of the system I use today showing: A hand stapler; A pneumatic Stapler; A box of Stainless Steel staples; A staple remover; A package and a half of popsicle sticks.

Just a recommendation - if you do use staples then staple them over a length of galvanized wire - it makes it much easier to pull them out again, tug the the wire to pull out the staple, much easier than trying to get a screw driver under the staple to lift it.and does less damage to the ply.

Hi Rod

?It's me again. Sorry to read about your experience with the hand stabler.?

Hi Olek

The difficult way to get a DUO 800 in the water.
Was there no ramp?
In any case, the boat can fly high ;-))
Have fun and good sailing

Cheers

Thanks, Jack. You are confirming what I am coming to realize - I need more of those cheap clamps. Of course there are places where they can't be used but where they can, so much the better.

H Rod, I used very cheap one hand glue clamps for this job.
I bought them at the HBM webshop for 1 euro per clamp, and bought 50 of them.

In the photo album of my ECO 85 electric you will see them a lot.

If I ever build another boat I'll buy 50 clamps more, as you can't have enough of these.

Regards,

Jack

Following up on my trial with the Rapter stapler. In my experience the manual stapler is a FAILURE.?
The task involved glueing stiffener timber to the plywood bulkheads for the ECO 6. I used screws at each end of each stiffener to ensure correct placement, with the intention of using the staples to ensure contact between. On my first try, I managed to get a couple of staples into the assembly and the stapler jammed. I could immediately see with a batch of epoxy mixed it was going to be too time consuming to un-jam the stapler. I abandoned the idea and used spring clamps instead to ensure contact. I ran out of epoxy mixture and spring clamps after half the bulkheads were done. The next day, I thought it only fair to give the stapler a second try on the remaining bulkheads after un-jamming it. The same thing happened.?
The stapler doesn't have enough strength to force ?the 9/16 inch staples through 6mm meranti plywood (two coats of epoxy) and into the Douglas Fir timber. The staples collapse, thus jamming the gun.?
I have contacted Duckworks to explain my dilemma. They in turn are "reaching out" to the manufacturer for their comments or suggestions. At the present moment, it has been an expensive experiment without the desired result. I cannot justify the expense of buying an air compressor plus a pneumatic gun so when I start applying panels to stringers I will revert to using screws and take the time to remove them and refill the holes.

Hello Richard

Thank you for this interesting picture.
Nice looking hull.
When will you turn him over?

Cheers

Bernd

Yes, the mast step as shown is sufficient. The load is not high, typical
for a lateen rig.

Bernd?

Quick question for Bernd and others who may know: only the mast step is shown on my Little Tri drawings. ?Is it safe to assume that step is all that’s required, or is the assumption that one would know better and put in some tube similar to the sunfish mast step/tube setup?

Thanks!

Looks great Pete. I always loved this design and you have built a terrific example, congratulations

cheers, Bryan

Impressive on so many levels - the workmanship, the setting, the perseverance. Ten years is true commitment and self-confidence. Wishing you continued resolve to reach the destination.
