Prolly canned road kill.

Did ya rinse the asphalt off it first?

[Bvas]

Nah. Just had to pick a little gravel out.

I like how it's adjustable.  Do you use a radiused fixture to clamp the lam in while boiling?

The adjustability is why I went to the trouble with it. There are so many possibilities of lam bow shapes with Perry reflex, recurves, R/D long bows, etc. that I wanted to be able to reconfigure everything without making a new form every time I wanted a different bow style. I also wanted multiple posts so I can define a specific radius to the limb bend instead of accepting whatever shape the limb wanted to form when bent over one or two posts.

This is more a proof of concept than anything. The posts will eventually have some sort of height adjustment built in so I don't have to keep brad nailing the shoulders in place. I figured I could live with this for a bow or two just to see if it works as I hope, then make a better set of posts once I have some experience with it. The posts are currently just 2x4 construction lumber that I cleaned up and radiused.

I just boiled the lams flat and then used the clamps and blocks to force them into the curve of the riser. I may think about a fixture for future work, that sounds like a good idea. The lams are ~0.155" where they are bending and it took a surprising amount of force to bend them into the riser.

Yeppers.  With a little garlic salt and some peppers and onions.

That sounds tasty. Do you have a recipe you can share?

What I have heard about boiling or steaming is you have about 15 seconds to get it clamped, but I've never done it?

steam has a lot of latent heat, maybe steam in place and tighten the clamp as you go.

Depends on what you are trying to do, but that is mostly correct. The heat comes out fast and the wood gets its strength back as quickly as it cools.

Make the ramp and lam. longer and flat




Mine is a good 2" to long

Hmmm, I can see that should reduce the forces involved and give a smoother bend. I will make up a block that clamps to the back of the riser and gives a flat ramp for the lam to ride up on and try forming it again, thanks.

it might also help if the two outside clamps bottom legs could hook in the same hole in the middle where the center clamp is

It does need to move over

I did the same thing one time Bvas, I bet thickness sanding end grain on that osage was a pain in the bu__.
Mine was Hard Rock Maple. mine wanted to burn when sanding
WE ripped it the wrong way
