I emailed Dennis about the dimensions for a good build table. It would be very convenient to be able to move the frame around during the build. Dennis responded that the build table they use is 48 inches by 36 inches and he recommended 24 inches tall for ease of assembly. This is a picture of what Brunton uses when they assembled the Super Stalker prototype.
I’ll try to pickup up some steel tomorrow to put one together before the frame get’s here on Friday.
