Cutting with a Dremel Tool

I need to trim a piece of 1/8" plastic that's been vacuformed. What's the best bit to use and how do I do it without melting or gumming up the bit. I've cut tubes and things using a composite wheel in my Dremel but have never cut large piece like this. I'm still getting the hang of using the thing. :confused Ideally I'd like to use a band saw but this is all I've got. Any pointers or what not to do would be great. Thanks in advance.

Score it with an x-acto close to where you want the cut to be, pop it off, and trim with a fresh #11 blade, maybe? how big is this part, and how thick is the vac plastic?

On my clone armor I used the little buzz saw shaped blade. Took a little getting used to but I found it to be quicker than using the abrasive based cut off wheel.

Yeah, I had thought about doing that with a utility knife but since it's 1/8" thick and roughly 30" sq. I thought it might be to beefy to do it that way. The part I'm cutting out is about 10"x18".

Size matters not. The score-&-snap technique should work just fine. It will help if you have a good table edge handy.

I've used the reinforced fibreglass based cut-off wheels... they don't "cut" cleanly, more like they grind the plastic down and you end up having to trim off this flakey excess with an exacto but I've been able to be extremely accurate in grinding the plastic part down to fit.

That is SOOOO cool. Unfortunately my house was built around the time when the automobile was still just catching on (1906) and have no garage so I have to use things that I can take out and put away easily. I definitely will get one when my wife and I buy our next house, the one with the two car garage and workshop. :thumbsup
