I made this one from Binghams plans for a 62" hybrid glass longbow.  I've been thinking of trying it for a wood tri-lam glue up sometime.  It uses c-clamps and strips of rubber and aluminum on the belly.

This one uses inner tubes for pressure.  When it came to gluing up a bow on it, though, I resorted to clamps where it curves at the ends.

Do you guys cook your risers on after the limbs are cooked?

For a glass bow, I glue up all the lams and glass and riser together and then cook them.  For an R/D wooden bow like Roy's, you can use Unibond to glue up the limbs first and then glue your riser or handle on later.  No need to use heat.  Got to admit I'm still a novice bowyer.  Here are a couple of build alongs that helped me a lot.  This one is Sam Harper's from his Poor Folk Bows website:

Kenny M sent me this one.  I bought the lams and glass from him and you won't find a better guy to buy from.  He answered so many questions from me that I wouldn't blame him if he changed his email address    :)

For the recurve form I posted above, I glue the limbs up first, then take those off the form and glue up a riser later.

For most other glue ups, I glue the limbs and riser together at the same time.

For bamboo backed bow and hickory backed bows where the riser is glued to the belly of the bow, most people glue the limbs up first and the riser later.  That way, they can glue some deflex into the riser area.  You could shape the riser first and bend the limbs around it, but it's easier to glue the limbs up first, then shape the riser to fit the curve in the limbs.
