Hi,
I am in the process of replacing the door gasket on my Marvel fridge. The gasket corners were mitered, not rounded as in some other models. I am having trouble getting an even miter at the gasket corners. I am sure everyone runs into the problem of the gasket deforming as you press down with a razor cutter and the result is an uneven cut. I have also tried aviation snips and scissors with mixed results. I even flipped it over and that seemed to help but only in one direction.
I am left with drawing the pencil line, and then clamping the gasket on either side of the cut line with two bar clamps. Cutting would be done with a razor blade paint scraper in a guillotine fashion on the cut line. That's all I can come up with. I can't figure anything else out.
Is there a hack?
Cheers,
Rod

Not sure if I will be of help, but I just did the door on the garage fridge not too long ago. I just used a small 45 degree square to mark the gasket & cut with a sharp knife. I made each gasket ever so slightly longer than I needed. The corners were not perfect, but when I melted them together, they turned out pretty nice. I used an old olfa blade to do mine. An old butter knife would be fine as well I suspect.
I made 2 L shaped pieces first, then dry fitted them both on the door card. I made final adjustments to the 2 remaining corners before melting together.
Maybe practice on 2 scrap pieces first.

I'm new to this forum, but just went through this with my fridge. Like you said, any two-sided cutting tool deforms the gasket and ruins the cut. The only thing that worked for me was a (sharp) box cutter, using a light sawing motion so the gasket didn't compress. I considered stuffing the gasket with something like foam dowel or balsa before cutting.

Hi Everyone,
That is really a cool tool, Coldspaces! I love how you could use it for 22 degree cuts as well as 45 degree cuts. On mine, the corners were really tight and not as rounded as on your Frigidaire. So, I just mitered all four corners.
I modified my technique to cut the gasket material. To minimize the squish, I took some scraps from the excess gasket material and placed them within the gasket body to help support the gasket so as to reduce the amount of squish going down when I cut. Instead of a box cutter and cutting with that, I found an older flat razor blade scraper and plunged straight down. The miters turned out adequate. The gaskets are now screwed onto the door now.
The original gasket had oval holes cut into it probably with an oval stamp to allow the screws to go through them. I took a leather punch I had inherited and marked the screw holes with a Sharpie and then made several punches around the Sharpie mark to make sure the screws had a hole to go through.
The original gasket corners all appeared to have been mitered. Though worn out and frayed on the corners, that was my guess. So, the result is that the top corner miters actually protrude about @1/4" over the door top edge. Not sure it was supposed to do that, but that's what it took to make the miter work. It's not that noticeable, especially at first glance. The width of the new gasket material was the same as the original from what I measured. Theoretically, I would have thought the miter would not show above the door top edge.
Now, I have to seal the miters. For those of you who used a knife blade to seal the seams of the miter, did you use an open flame like a lighter or just place the knife in an oven to heat it?
Coldspaces, what did you do to the miters on the bottom corners of your fridge? How did you seal those seams?
Cheers,
Rod

Just a minor tidbit. In researching how to replace the broken and brittle interior trim I found a photo of the original gasket corner on this model fridge and they are not fully mitered. The corners were cut with a 90 degree angle, but the cut didn't go all the way to the edge severing the edge. Instead, the cut went about 4/5 of the width of the gasket material leaving it connected much like the tool that Coldspaces tool creates cuts. The result is a more rounded corner which had I done that wouldn't have ended up with protruding corners from the full miter.🙄
Maybe someone coming after me can use that info. I am leaving it as. I don't have the time or money to redo this again. I doubt the Gasket Police will be coming to my trailer anytime soon.
Cheers,
Rod

That is a neat tool. I saw one on eBay and bought it and it arrived this weekend. It uses an unusual size blade that I need to find somehow. |
