Small little "bow form" making problem...

I guess it is probably a little more of an annoyance than a problem really. I have been making simple wooden forms to clamp bows to during glue up, made from 2 x 10s or so 2 x 12s, with a strip on aluminum gorilla glued to, to avoid the bow being glued to the form. These have worked best for me and gave me the best glue lines, verses the other ways I have tried , which are innertubes and forms where you bind the stave down on. I am thinking this is because I am using tb3 to glue the blank together. What has been giving me a bit of a headache is getting the form cut out perfectly 90 degress everywhere. I know it seems simple enough?
I have been cutting out form on my bandsaw roughly and than finishing up with my farriers rasp. I was wondering what would be a better way? I was thinking a spindle sander would work to get the cut 90 degress?

When I do glue ups, I proceed in this order, draw knife, spoke shave, block plane if needed, then a cabinet scraper.
Angles are not an issue unless I really butchered the profile.
Take that for what it is worth.

I use a drum sander on a drill press to square up the surface of the forms I make. A spindle sander will work too.

I too use a drum sander on my drill press. I double check that the drum is square to the table before I begin.

If you start with a 1/4 inch thick plywood or MDF and then get the shape you want... trace it onto your 2x10 and then cut it out on the band saw. Then screw the pattern back onto the 2x10 and use a pattern bit on a router. That works slick and I have used it to make all of my fiberglass forms. Just another thought I guess...
