Gasket making
I need to make a gasket. It will be about 2 x 3 inches. Pretty simple
stuff. I made one before for my welder carburetor. IIRC, I laid a piece of paper on it, and rubbed it with dirty fingers until I got a pattern, then carefully cut it out. It lasted a long time, and would have lasted longer, but I left it full of gas, and it varnished. I have cleaned the carb really well, and blown out all the channels and chased them with pipe cleaners. I figure to use the piece of white paper again. There are only four bolt holes, and they have a lot of room for error. I figure this time, I'll use an X-Acto knife to cut out a lot of the bigger pieces, and a improvised punch to get the bolt holes. Any tricks to gasket making? I have enough material to make about four in case I mess up. Just go slow and easy, I guess. I was going to use a tiny ball peen to cut off at the outside edges, but decided to leave about 1/8+" sticking out so I don't have to worry about having too close tolerances, and having a potential leaking spot. I can just cut outside the line with scissors, and get it pretty close. I thought of taking a digital picture, and enlarging it to exact duplicate scale, and then using that for a template to cut the gasket on a flat piece of plywood. Might take a little time, but I think I can do it easily, just include a tape in the pic, and keep adjusting and printing until it prints dead on. What would you do? Steve |

Steve For years people have been laying the gasket material on the part and carefully tapping with a small ball peen hammer to emboss the outline on the gasket material. In some cases like the outside edges you can actually cut the gasket to size with the hammer but in more delicate locations it is usually more practical to cut to the embossed line with a knife of scissors. I usually punch bolt holes with a hole punch. As I'm sure you know, real gasket material beats everything else for long life and sealing. -- Cheers, John B. |

Place the gasket material against your part and carefully tap with a ball peen hammer.. 2nd that. surprised it took this long for somebody to answer. made 100s this way. Karl |

I figure this time, I'll use an X-Acto knife to cut out a lot of the bigger pieces, and a improvised punch to get the bolt holes. Except for the paper, good. I've used cardboard from a cereal box before, but that was because I couldn't find gasket material at my local auto parts stores. Tim has the right idea. DO get the proper material. It comes by the foot (historically) or in several foot rolls (more recently). Any tricks to gasket making? I have enough material to make about four in case I mess up. Just go slow and easy, I guess. I was going to use a tiny ball peen to cut off at the outside edges, but decided to leave about 1/8+" sticking out so I don't have to worry about having too close tolerances, and having a potential leaking spot. I can just cut outside the line with scissors, and get it pretty close. I've made them with a ball peen hammer myself, but I've also seen fellow students (Universal Technical Institute, 1972) CRACK and/or dent carb bodies doing that. I recommend against it. No, better is to measure and cut off a piece gasket material which will be large enough to do the job. Lay that out on the bench, lay the carb body on it, trace around the outside, and cut that line with an exacto or scissors. If there is linkage in the way, guess on the wide side and trim later. Then draw a parallel line around the inside so it is just a bit wider than needed, increasing it to a larger diameter where the screw holes will be. Carefully use the exacto to cut that outline. Now use a hollow punch to cut the screw holes. HF has a set for $6, if you don't already have a set. I thought of taking a digital picture, and enlarging it to exact duplicate scale, and then using that for a template to cut the gasket on a flat piece of plywood. Might take a little time, but I think I can do it easily, just include a tape in the pic, and keep adjusting and printing until it prints dead on. No, I think printing would only increase parallax errors. What would you do? Once you have a good gasket, make a few more, keep them in a baggie (backed by a little piece of cardboard to keep them from betting bent) and save them with your welder manual. Staple it to one of the sillier warning pages at the front. I'd start by going to a decent auto parts store and getting some 1/32" thick gasket material. You'll know it's a decent auto parts store if you say "do you have 1/32" thick gasket material?" and they say "yes". Ayup, I heartily second that, Tim. 1/32" at minimum. I used to use long-fiber wheel bearing grease on that material to give it a longer life. They dry out terribly without it. Goop up the cut gasket, let it sit for half an hour to soak in, then carefully wipe off the excess. Gas will eat away any grease within the carb body, but the grease will keep the gasket from sticking to the carb (or, worse, a timing chain cover), so it is easier the next time you rebuild. I'm so VERY glad that automotive technology moved to EFI and I don't have to rebuild carbs any more. g -- Stoop and you'll be stepped on; stand tall and you'll be shot at. -- Carlos A. Urbizo |

Steve Id take the gasket material, lay it on the carberator..and tap it firmly with a plastic or brass hammer..alll over the top of the gasket.

: Id take the gasket material, lay it on the carberator..and tap it firmly with a plastic or brass hammer..alll over the top of the gasket. If you were an old-school mechanic, you'd do it this way. Coat one surface with Hi-Tack (or a gasket sealer compatible with the job, if Hi-Tack won't work), and stick it down flat on the piece to be gasketed. Hold (press) it flat until the Hi-tack grips and holds. Finger-press or rub the surface to locate drafts and bolt holes. Just indicate them with slight depressions, don't try to push them through. Use a tiny ball-peen hammer, like a modeler's size (total head length about 2" and weight about 3-4oz, and LIGHTLY tap on the inside edges of any hole you wish to cut out. As you tap, the holes will become better defined. If the hole has long straight sides, use the flat end of the hammer for the sides, until you approach the corners, working more and more toward the very tip of the ball as you get into small circles or small-radius corners. Progressively, you can cut all the way through the gasket material without any damage to the work or the body-portion of the gasket. Fish out pieces that go into holes with and awl or tweezers. The gasket will be an exact fit, as if it had been die-cut. LLoyd |

There is a trick that is rarely needed but sometimes helps. If your Exacto knife, surgical scalpel or other Very Sharp Blade isn't cutting the gasket material -- gasket paper, cork, whatever -- cleanly, there is a device used by dress makers that may work: a fabric cutter, sort of like an Exacto knife but with a razor-sharp rotating wheel instead of a static blade. Cool device. (Do remember to use it on a surface that won't blunt it in one rev.) 99% of the time, scissors, Exacto knife or Bard-Parker scalpel plus a cheap set of hole (hollow) punches are fine. -- Mike Spencer Nova Scotia, Canada |

Not sure if it is still available as a spray, but the msds for the brush-on indicated it is Acetone, Methyl Ester of Rosin, N-Hexane, Rosin, and Acrylonitrile Butadiene polymer Because more recently, a few years ago, I had to seal a problem settling bowl on a Wisconsin air-cooled. Leaked like a sieve. Experiments showed that gasoline quickly dissolves and cleans off HiTack very well. New can from store, same. New can sent directly from Permatex, same. Is it new gas additives/composition? Changes in the produst that even the engineer at Permatex didn't know about? My memory has a huge hole in it? Yes, most likely. It's probably being dissolved by the alcohol in the fuel, and maybe even some of the new, highly-toxic additives. None of that was around way-back-when. (And it shouldn't be around today, damnit. I lost over fifteen percent of my gas mileage to the bloody oxygenated fuel we use today. I'm just glad it's E15, not E85. I can't imagine how gutless engines would be on that.) Is there a similar, alternative non-hardening, spray-on gasket sealer that's impervious to gasoline (and diesel, for that matter)? ObMetalworking: The Wisconsin was intended to drive a 300# air hammer but turned out not to be big enough. A 3-cyl Deutz diesel *is* big enough. Pictures, man! Pictures! |

The VG4 doesn't make as much power as its size might make you expect!! The Wisconsin 4 (I forget the model#) is about 24 HP, enough to run the hammer at idle but not under load. The Deutz is ca. 40 HP. The hammer was originally run from a 15HP 400V 3PH motor. I salvaged the motor's shaft to use as a jackshaft between diesel and hammer. Used to run the flathead VG4D engines on a lot of swathers and balers. Heavy slugs. Fairly torquey, but about 1800 RPM wide open. |
