ebinmaine 68,514 #2 Posted October 8, 2018 Interesting method. I've always just traced and cut carefully. Do you use the item you're making the gasket for as the template? Share this post Link to post Share on other sites
JAinVA 4,623 #3 Posted October 9, 2018 (edited) That is an age old method for making gaskets.Good tutorial.My dad showed me the method over 50 years ago.When I was a wet behind the ears millwright apprentice my instructors seemed irritated that I knew how to make gaskets as well as they could.But then I was always a smart a#s.I wished I could get a roll of gasket material as big as what you show.

Do you use the item you're making the gasket for as the template? Yes you use the part as your template, use the small end of the peen to gently tap along the sharp edges. On the large Onan oil galley gasket I first tapped out a bolt hole to insert a bolt to keep the gasket material in place. One tool set that I recently purchased and leave at the farm was a set of transfer punches. I do not own the Farm but have the use of their shop day or night as a token of appreciation I sometimes leave a cash offering or tools that we can both use. They have an 85 amp name brand plasma, a couple of mig"s, Lincoln square wave welder, metal lathe and a 50 ton press that scares the &&^% out of me. Rob the owner of the farm runs a 20,000 acre grain operation from a wheel chair. Edited October 9, 2018 by bcgold 1 Share this post Link to post Share on other sites

Get your parts guy to go thought his book to see what is available besides what they stock. If you commit to a full roll there shouldn't be a problem with your purchase. 1 1 Share this post Link to post Share on other sites
bc.gold 3,403 #6 Posted October 9, 2018 My old proto has a split handle, I'm going to drill some holes then insert heavy copper wire then rivet the ends over. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,107 #7 Posted October 9, 2018 Had to make a complicated gasket for a Zenith carb. The carb ended up on a flatbed scanner and after a few tries got the scale right. Used spray adhesive to mount the copy on gasket material and cut it out from there. Worked good. Garry 1 Share this post Link to post Share on other sites

ranger 1,762 #9 Posted October 9, 2018 Another usually more precise way is to use ball bearings from old ball races, press one over the hole with the gasket underneath, it should stay in place, then gently tap the ball. This way you won't / shouldn't miss and damage the edges of the hole with the hammer. Save different size bearings for different size holes, but always use a larger one than the hole. Another thing that works is a "piston" from a "defunct" axial piston hydraulic pump, remove the bronze foot from the piston, you then have a "ball on stick" which is easier to hold and hit! 1 Share this post Link to post Share on other sites

Good thought and the larger displacement pumps would have larger heads 1 Share this post Link to post Share on other sites
