A good reason NOT to cut plastic with a bandsaw and reminder to me why I used to use a router to cut my plastics.

Making a cake turntable for my daughter I rough cut the 13mm thick copoly plastic on the bandsaw and wished I hadn't as it took the rest of the day to sort the mess out and get the blade free for replacement.

Having just replaced five bearings in my Big Band Saw I notice your bottom bearing especially on the LHS has given up the struggle. Around this area is a mongrel to keep clear I am fitting a fish tank pump to blow that area clean in my saw. Does the build up cutting plastic problem result in too much pressure I find thats my problem always in a hurry at the wrong time.Aluminium can do wonders as well.

Felt for you kneeling under a bandsaw ....not fun.

All sorted now Mark but I put this up as a warning of what can happen, I was totally unaware of what was going on underneath the material.
I walked away from it after I had cut the shape and wondered why the thing didn't wanna move next time time I switched it on.
Soon found out why init?

It's a bugger Brian. I used to cut a lot of Perspex on the bandsaw, been there got the tee shirt. The plastic fuses back if you're not careful. It's a lesson learnt.:sob:

That's nasty Brian. I'm glad I didn't send you any or I'd have got the blame :funny:

I've never had a problem tbh and regularly cut polyprop which is copolymer without issue. It's only 3mm thick though not 12 so clearly much less heat build up. I'll watch mine carefully in future.
