Okay so today I needed to make a few gaskets......drawing them out was not an issue....cutting the outside edges was simple enough.....used a hole puncher for the bolt holes......so moving along pretty good.....then pulled out the old family exacta knife ( not sure that is the name ....but it is the one with teh razor looking blade at the end)......now it may not have been sharpe enough....but when I finally finished cutting out the middle it was a little ragged around the edges....I am guessing I could buy some small snip type scissors to do the smaller more detail cuts....anybody got any suggestons or ways that you would do this?

I use a sharp wood chisel on a piece of 2X12" pine board, not to dull the chisel. It will cut the cork cleanly. I have 3 different sizes, 1/2" 1" and 2".. Hope this helps..

I use a really sharp, new blade in my exacto knife, a set of chisels, and I have a couple of broken curved wood lathe tools that are sharpened up good. I have found the last items to be a good tool if the curve is close enough for what you are doing.

I have almost quit using cork altogether and have switched over to the thicker stuff they sell at automotive stores that looks like charcoal colored paper. (or posterboard sometimes) Much easier to work and rarely rips out.

I have a pair of sissors I use on most stuff. I think there made by Fiskers (not sure if I spelled it right) they are a little heaver than normal ones and have a serated outer edge. I also use a punch, some of which are just rifle brass honed or filed a bit to sharpen the edge more and my pocket knife (I keep it razor sharp).

This is what I mostly use. Sounds likely to be what Alan uses.

Instead of plain cork, I use the rubberized cork. Much better seal & life.

I use what is commonly referred to as a box cutter. I use the Olfa brand cutter with the segmented blade so you can always keep a sharp edge. I've used that rubbarized cork that Daniel is referring to and it seems to seal well.

Industrial supply houses are also a good source for gasket material in many different thicknesses.

Gasket thickness is critical in many applications as it sets the internal clearances.

to cut alot of pieces I use a ball peen hammer. Set the gasket material over the metal and tap with the round end lightly on the gasket at about 45 degrees to the edge of the metal. It gives a nice sharp cut avery time.
