I built my oven 12" wide x 22" tall and 88" long, I followed the Binghams plan. I found that I could use four 100 watt bulbs to maintain 165 degrees. I'm using the 150-180 degree thermostat from Binghams. I built a 2x4 wood frame under the form and added castor wheels, I store it under my build bench, I just roll it out when I need it. I also bought a good pin timer, I set timer to run the pre heated oven for 5 hours after I put form in oven after glue up. I use air hose forms and the recurve form I built is 15 inches tall I think my longbow form is 14" tall.
