First bow form failure.

[Susquehannariverarcher]

I'm attempting to make my first bow (sorry have been posting so much) . It's a laminated long bow. I have a few hiccups here and there. But tonight I thought I was finally ready for my test fit and glue up, until I realized the top of my form seems to be warped. So it looks like I'm starting over.

I used birch ply wood laminated together from lowes. This time I'm thinking of trying LVL beam is this option better? I'm honestly not sure how my form even got warped, I'm guessing its not salvageable.

Is it bowed from tip to tip? It could be fixed
Pictures help

I'll get pictures in a bit. But basically it lines up good for 3/4 of the form and the last 1/4 is about a half inch off.

The form is upside down but 2 pieces of 3/4" plywood 6" wide glued together and then screw and glued to the bottom of the form.
Heavy steel clamped to hold the form straight while the glue sets, I used 1/2" dowels also.

I gotcha. I'm doing an air hose form with with metal brackets from kenny. I got to thinking last night that potentially my holes for the bolts might not be square and that could be the issue, I'm going to drill them on a press if I can my hands on one tonight.

As long as the bottom form that the bow sets on is straight and not twisted, it shouldn’t matter much if that top form is warped a bit. Just make sure the air hose is lined up straight on that lower form and don’t over inflate it…. You just don’t need more than 50# pressure.

You could also just bolt a piece of angle iron to the warped form to straighten it out.

Thanks for the ideas once again Kirk. I got stuck at work late and didn't have any shop time tonight. Hopefully I can work on it tomorrow witb a clear head and come up with a solution. All of you on this forum have been such a wealth of knowledge that I very much appreciate.

Could go topless.

Could go topless.

Definitely an option!
