Just wondering if you Guys know about the Winmiter program? Invaluable for frame building if like me you're too poor for real tube notching equipment. If you haven't come across it, google Winmiter and download it free. Punch in your tube diameters and intersect angle and it'll give you a printable template of the required notch to wrap around the tube. Attack it with the cut-off wheel and die-grinder, and you're laughin. Awesome!
Apologies if this is already common knowledge.
