Hey there Bill,
I've been following your thread here, and share your concerns and excitement as well. i just put my first riser in my brand new oven i built yesterday!i've got a pronounced longbow kit from Binghams and am using the air preasure form system. boy there sure is a lot of work in building the forms!
Before i glue up my first bow today i'm going to use the tapers i have with the kit to grind sled for making more. I've got a bunch of different hardwoods in stock. i want to make my own laminations for future bows. This taper thing seems to be a well kept secret. i have found no books what so ever on the subject, and many bowyers are pretty tight lipped about sharing their experience.....
I hope you plan on posting a few pics....i'm looking forward to seeing what you have going
