I'm making an outboard bracket, and it's all a bit...custom.
I need to fasten the 25mm ply 'false transom' to 38mm diameter 1.5mm stainless pipes which will transfer the engine's weight and thrust to stronger points than the boat's light glassfibre transom. No need to suggest alternatives - this will be fine, when it's done.
I looked up 'saddle clips' which might secure the pipes to the wood, but the size I need were almost £5 each, and I'd want quite a few...
...so I actually made my own, one big one for each pipe, by bending sheets of 1.5mm stainless into a shape that would fit round them.
Bending stainless is difficult (I was dazzled to achieve anything at all with my curious mix of basic and broken clamps and vice)...
...so there isn't a perfect size-match between the outside of the pipes and the inner diameter of the stainless curves...
...it's close, but not perfect. I'll need some sort of rubber packing, so when it's bolted on to the ply, it's a good tight fit.
I thought something like ordinary bicycle inner tube is grippy and hard-wearing, but when I proposed using that to pack-out the uneven support behind a U-bolt in recent years, I was warned that it will dry out and harden, losing its useful rubberiness. What's recommended instead?
