So being as I'm new to this stuff it may be a silly question. The form I presently made requires overlays on the riser after glue up.
Can one not make a form where the riser doesnt require that?
I'm refering to a one piece longbow form
Adding pieces after the fact seems like too many steps and not overly easy to get tight seams.
Am I missing something?
You need tip overlays too, so do the riser and tip overlays at the same time.
Too much going on at 1 time but it could be done.

So, do you want a riser that doesn't require any overlays or a form that allows you to glue the body of the bow and the overlays in one step?

I guess I figure a riser block that's only cut once.
When added into the stack it needs nothing else.
When it comes from the form just shaping.
Tip overlays are not a concern as it is quite simple
How do we make the glass shine again when u hit it with sandpaper?
Got a few scuffs!
This help?

When you spray finish the glass will clear up. That said it all needs sanded with 220 to break the glaze on it so finish will stick...
Seems like that would be hard to accomplish with clamps or a hose. On the other hand it would be relatively easy with a vacuum bag, as everything is sucked into place from all directions keeping those little bits and pieces located.
Anybody used a vacuum pump to do a build? I bought a vacuum setup to veneer a mantle for a fireplace and I've only used it a couple of times. I've wondered if I could use it for bow making.

As Flem says, it would simplify holding all the lams in place while drawing it down. The downside is that you only have 14.7psi (at absolute max) to clamp the layup and I see lots of guys say they use 60+psi in their air hose set ups. You may need to add some extra clamping with the vacuum method.

Nice! Thanks, Flem. I guess just having a vacuum pump is a long way from
Using it for a bow build.

Sweet. Nice to see atmospheric pressure will do the job of getting the bow tight to the form.

Seams like that would be a pain to keep everything lined up during glue up.
There are six steps to a glue up in my one piece bows and 10 steps on my 3 piece bows with all the accents and I beams ect... if I do mosaic accents that's another 2-3 steps in its self
no one step takes very long and there's always something else to work on while each step is curing out. Take your time and enjoy the process!
