Gaskets

[Homemade]

Don't know if this should go in chainsaws or repairs or mowers and more. But I'm repairing a mac325bp backpack blower. It has leaks by the crankcase gaskets and the intake gaskets. I'm wondering if you guys ever make your own gaskets or use a sealant with gaskets, or just sealant with no gaskets. The gaskets are still available and will probably just order them regardless but I'm also asking for my solo 667 that I want new gaskets for but there no longer available.

Never thought about the hole punch set. I've done the gasket paper but bolt holes are the hardest part. Do you add anything to the paper? RTV or form-a-gasket. Just to help it stick.

A leather hole puncher tool is nice too.

permatex has a product called "spray a gasket." I used it to make a paperboard head gasket for a brigs mower. I used a couple .30 cal rifle cartridge to punch the holes, but ended up bending the cartridges.

If those HF hole punches are like the ones I got then you should get a piece of brass plate to prevent dulling and get cleaner cuts. They do come in handy when you just need a gasket or need to add or enlarge a hole. I make several smaller gaskets every month especially those NLA ones.

@JMoney. Thanks for the thread redirect. Lots of good ideas in there.

Anyone use "high tack", whether permatx or loctite, to help a bare paper gasket stick better.

Indian Head gasket shellac.....
great stuff

The high tack is what I used for the head gasket on the mower. I do believe the copper spray-a-gasket is preferred though due to the higher temp tolerance.

Lock Tite 5900 rtv is the standard of the world in automotive sealants .It's used by about all the major manufactures in the world .Indian head has been around since the days of the model T Ford and works as good today as in the days an automobile was started with a hand crank .
I seldom use any sealant on a head gasket .Some never seeze or Kopper Kote maybe .
As far as paper gaskets,in my life time I've made everything from oil pan gaskets for a D4 Caterpillar to carb gaskets for an antique chainsaw engine .Anything that will punch a clean hole will work .
