• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

Okay,
I think of myself as a fairly intelligent person.Have a four year degree,fly widebody aircraft all over the world as a captain for a major cargo airline,but I just cannot figure out how to keep from tearing up hole saws when cutting tube.I have gone through about 6 saws.Every time I cut a tube I rip the teeth right off.I go very slow maybe 400 to 500 RPM and use lots of lube.Is it the tubing being 4130 and I am using crappy saws? Are there any super tough saws out there? Help me Help me Please!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
