Yes, I know you've seen these, but I reckon they're great. This is what I spent my afternoon making. Eighteen of the sods ... probably don't need quite that many but that's what I wound up with.
Clamps.
Yes, clamps. Common or garden type clamps (see attachment - I'm not drunk, honest).
I want to fit two rubbing strips to Sixpence, one in the normal gunwale position, another at the bottom of the top plank. That means I need a clamp with a throat of ... a lot more than the clamps I have. So I made these.
The basic concept is simple. Two bits of wood, held together with a bolt. The open end slips over the two things you are clamping together, a wedge gets driven home at that other end.
In this case, it was a tad more complicated because the inwale is already fitted. This means that any clamp needs to reach around the inwale, and reach down to the bottom of the first clamp.
So, if you look at piccy number one, you'll see the clamp from inside the boat. The bit of packing at the bottom of the clamp is nailed to the clamp and is just a packer to get around the inwale.
Now, go to the outside boat shot. The piece of scrap timber is just there pretending to be the rubbing strip (I've got two lovely bits of 15' long kapur for the real thing :D )
I'm particularly proud of the wedges. Oh sure, anyone can cut wedges, anyone who knows how to do it. I cut eighteen of the things on my Triton :D Worked out how to do it myself :D Hey, it might be obvious to you but it was a voyage of discovery for me, and I had to do each with two cuts as my saw only went half way through the block of wood.
Fitting the clamps is easy. Place the clamp in the right place, drop a wedge in the top, make sure the rubbing strip is in the right place and whack the wedge with a mallet. Quick and surprisingly effective.
So, in a few days time, I'll post a piccy of Sixpence with a rubbing strip clamped and glued and place:D
Incidentally, I could have bought F clamps with a throat deep enough to do this job. They'd cost me about $15 each (I priced them). These eighteen clamps cost me under $20 for the LOT;)
Cheers
