Tips for cutting door gasket?

[BryanH]

Ok somebody help me... I'm trying to replace the door gasket.  How the '>  do you cut straight miters on the door gasket corners?  I've tried a utility knife, tin snips and scissors.  Doesn't matter what I use, the gasket rolls enough that the miter is off and the edges don't line up well.  There has to be a clever way of getting a good edge.

I use a razorblade and push down on the cutline, rather than pull across it.  This keeps the rubber from rolling. Once you get a clean top cut through the bulb the rest does not show.

One trick I use is to utilize a combination square.
This tool provides for 90 degree or 45 degee angles and once I press down on the gasket, I can usually get a very straight cut that will line up nice...

Are you talking about a framing square?

Here is what Jim is talking about. Very handy.

That's not exactly like the one I use eventhough I do have the one pictured, but this type will work as well...

I like jim use a combination sqaure. I also cut a couple of 4" squares from sheet metal and insert them into the corners when gluing the rubber corners together. I use loctite super glue in the pin. If you have gaps in the rubber they can be filled in with glue. '>

I had been using a combination square also, and I even tried clamping the gasket down to keep it from rolling.  I tried Glen's suggestion of pushing down on a razor blade rather than pulling it across and that seemed to help the most.  Even found a neat, and cheap ($2.50), window scraper in HD that uses standard utility knife blades but exposes the full 2" of the bade. Between the pushing and a little bit of super glue filler I think I've got it licked. Just hope the next one is easier and cleaner.

Thanks again for all the tips.

Terry -

I had found the Loctite glue when I restored my liner for my Cavalier 55D, works great doesn't it? But, I think your use of the small squares of sheet metal as a jig is an excellent idea.

That will definitely help during my next restoration project! '>

The squares were a great idea.  I had been using my metal bladed putty knives.  Thanks again guys.  My gasket and newly restored door liner are installed.  I'll be out of pocket all weekend, which is going to kill me, as I'm only about 8 hours away from having the machine COMPLETELY FINISHED.  Will try to get it done next weekend but may be disctracted by the Westinghouse cooler I'm picking up that weekend...  Anyway, whenever it does get finished - I couldn't have done it without the help.  Thanks.
