I'm looking for suggestions on repairing/replacing the plastic lid on an old Lortone 10-inch saw. During a move and later in storage the lid was badly cracked. I didn't notice it until I started cleaning it to get it into service again. It has a 10-inch crack halfway across the top and a couple of smaller 3 or 4-inch cracks as well.
I thought of epoxy but the lid's so oily I doubt I could clean it enough for the adhesive to stick. Ideally I'll be able to find a replacement, but with Lortone out of business it's very unlikely. It's an ancient ST-10 model that was later replaced by the LS-10 (I think). I believe they use the same lid -- they look alike.
Other options are fabricating a new lid from plastic sheet or making another kind of repair. Anyone have a source for plastic? I've looked locally but haven't found a supplier so far. And how he heck do you form it?? Anyone have ideas on repairs?
All suggestions will be greatly appreciated. Thanks!

Is this a curved lid?

Yes. I found an image but am having trouble uploading it. I've just been called to dinner so I'll post it later.

If you only care about sealing it, maybe clear silicon caulk would work? Like the one used for sinks and tubs.

Yes. I found an image but am having trouble uploading it. I've just been called to dinner so I'll post it later. Posing a link is easier. If you can buy one that is probably the best way to go. If not, I think you could make one (with some effort). It is hard to tell from the video but it looks like the lid is made from flat pieces that are connected with metal angles (at least on the front) and then probably sealed with some sort of epoxy. I think you could make this with clear acrylic sheets that you can buy at hardware stores like Lowes. They have cutters that you can use to cut sheets to size (I used a box cutter) and if I remember they have some sort of epoxy or glue to connect sheets. You could use the old metal support angles on the new sheets. I have used these sheets to make plates to seal hand holes on the Covington lid that I have. I also drilled small holes and used bolts to connect magnets so I could easily keep them on the lid and take them off when I wanted. The stuff is hard to cut so it takes multiple passes with the box cutter and a straight edge to be able to cut the sheets to size. If I remember right, I cut as deep a cut as I could (maybe on both sides) and then broke it on a table edge. You could probably use a saw to cut them but I bet that makes a mess.

Pretty sure they are 1/8" plexiglass Acrylic. If you have access to a heat gun and a length of tubing or pipe that matches the inside radius of the bent corner, they are relatively easy to fabricate. I may be getting a couple LS10 baskets in a few weeks, if it happens I will be fabricating lids for both. The material is readily available, check your local stores for the covid cough screens in the back room, or FB marketplace for surplus pieces, cuts nice with a fine tooth blade on a table saw.

As far as patching goes, the acrylic glue is really a solvent that welds it. With a reasonable amount of soap degreasing and a good rinse, the solvent should cut through the remaining oil residue and hold it together, but backing it up with corner brackets like in the video won't hurt. Weld-on makes the acrylic glue, but pvc pipe cement also works if you have it on hand. The patches are seldom pretty, but they make the saw usable.

Rockoonz Many thanks Lee for your great suggestions. I appreciate the specific product suggestions particularly -- it's an area I'm totally ignorant about. There are many!

Many years ago when I aquired my vintage 18 inch HP saw, it had a large crack along the curved back and smaller cracks where the side and back of the top meet and also where the hinges mount. I ended up cleaning the area with Simple Green and then got some fiberglass resin and some fiberglass mesh strips. Did both the inside and outside but probably could have just done 1 side. It doesnt look pretty but its lasted over 12 years so far with out any issues. If there was ever anything you were going to use in a well ventilated area, fiberglass resin is it!

cut a dowel to fit in the corner where the bend in the lid is, trim it back a little so it is even with the folded corners. Get a sheet of Lexan (stronger than plexiglass and doesn't crack when you drill it) and cut a piece to fit in where the lid goes. Drill holes and bolt it to the hinge, get a heat gun and slowly melt the lexan so it folds over the dowel, you have to be careful to keep the heat even or it will get kind of warped, if you have 2 heat guns it helps. I always cut it a little long and then after it is formed I trim the end for length. It is really easy to trim using a carbide cutter on a flat surface. Drill it for the handle and install the handle.
