• 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.

Hi guys, Just wondering what the experts think about the differences here. I've heard that laser cutting can set up internal stress and cause fatigue cracking.
I did a search on the forum here and found that jimthepilotguy mentioned a problem with water jet cutting back in 2012 due to the cut lines.
I would imagine that it would be good practice to polish the cut edges of both laser and water jet cut parts. At least with the water jet cut parts there would be no heat affected zone and probably no internal stresses.
Are DXF files for the skybolt available? If not, I can draw these up in Solidworks for myself and anyone else interested.
Eric
