I don't have room in my house for a scroll saw. I want to cut vinyl records also - actually into 2" squares for a craft project. Anybody have a link to the 'hot knife' mentioned by oddartist? I would like to know what it is, where to buy it, how to use it!

On a small scale you can get away with a normal hacksaw that has a very fine blade, about 5 bucks at the hardware store.
You can try the cut and freeze method too.
Here you use a really sharp knife first to make (straight) cuts deep enough to be clearly visible.
Then you put the thing in the freezer for about an hour and break it over a straight edge like your kitchen table.
Should snap clean off.

I've had terrific luck with using a scroll saw. You can see some of what I've done at www.LPVinylArt.com. I do like the idea of heating up a metal ring and pushing it through. Will have to try that for a couple of things. BE CAREFUL of the fumes whenever heating vinyl, they are very bad for you!

You could also heat up the record (100 degrees celsius for around 1.5 minute / 2 minutes). Just mark on the record a cuttingline and cut it with scissors. A con with this method is that it cools very fast so you probably have reheat the record again. When you got the piece you want but its bent you can simply reheat it again and put it between two books to get it in its correct form.

I use a lot of vinyl records in my art. My favorite tool it the 'hot knife' I picked up at a craft store years ago. It's essentially a razor knife that heats up. Costs less than $20 but I got 2 for $5 each on sale.
Go slowly, don't press too hard, and use a cuticle remover to take the build-up off the edge. I'll do an Instructable the next time I use it.

Hot metal ring*, you'd have to get it ~250oC in an oven and give it a firm-push.

L

* you might find a steel food-can of the right diameter.

You need a 3.5 inch diameter hole saw, think that is the size of the label.  Maybe freeze or stick the record in the fridge before you cut if you see the vinyl gumming up.  Get the drill up to speed, preferably in a drill press and have scrap backing for the drill follow-through to prevent tearout on the other side.

If I was going to use an electric saw for cutting vinyl records I think I would use the scroll saw as this has variable speed so could cut as slow as you wanted without melting the vinyl and jamming the blade

i would definitely use an electric saw here most power saws like a table saw, miter box, band saw would work

My wife turns LP's into large candy dishes by "warming" them in the oven for a bit, and taking them out and using a steel gelatin "form" to press it downward into a bigger bowl.

. Vinyl is short for polyvinyl chloride - more commonly known as PVC. A hacksaw works well.
. Most electric saws will melt the PVC as you cut - you need something that moves pretty slow, so as not to build up heat.
. A gasket cutter would probably work.
