Laser Cut Gaskets using a low power laser.
« on: June 04, 2009, 11:00:55 AM »
My favorite model plane has an aging OS 61 which is now due for new crankshaft bearings and a clean up. The new crankcase gaskets have always been a pain to make (can’t buy them anymore – people don’t still use engines this old) and as I saw a posting recently about laser cut gaskets I decided to give it a try. I scanned the crankcase and got a reasonably good image which I converted to vector and then to GCode. Cutting at only 40 mm/min the 150mW laser made a pretty good job and didn’t set fire to the thin material as I half expected it to.

A couple of pictures of the laser and it’s control box on my Z axis, the finished gaskets and where they fit on the crankcase.

Tweakie,

Very nice!! I know it's a pain to cut a form from rubber. Now it's rather fun for you. Well done!

What's the material?

Hi Daniel,

It's the rust preventing paper that they use to wrap up tools etc. None of my proper gasket material is thin enough for this job.
