I’m trying to cut some vinyl upholstery on the Lowrider. The laser cutter has this annoying habit of releasing chlorine gas so I’m thinking about a drag knife but I’m not sure the vinyl sticker one from Ryan’s shop is going to work. I also need some way to keep the material flat. Maybe stretch it ov…

There are some thingiverse mounts for a box cutter type blade that might work. Not sure how those will work turning sharp corners …

I saw those, I will try printing one tonight. The main problem is the hold down. Maybe a vacuum table? I would love to go the tangential knife route but I don’t have any more drivers for another stepper on my mini rambo. Thanks

Yea i would think a vacuum table would work - i’ve seen one built for cutting foam board for model airplanes. Just an idea – take a look at the needle cutter used to cut foam boards for model airplanes. Depending on the thickness of the vinyl it might be able to perforate the material enough to tea…

Pure conjecture since I’ve only read about this “trick,” but consider using contact/shelf paper. It works just like the painter’s tape “trick.” You apply the contact paper to both the spoil board and the back side of the material then glue them together. I think the blurb I read said they used Su…

I was going to suggest trying one of the sticky mats they use for Cricut or Brother machines, but I don’t think they come a yard long. You can get just the sticky glue from online suppliers and make your own. Maybe repositionable spray adhesive ( 3M Repositionable 75) onto a foam core backer?

I have cut some vinyl on my mpcnc. Ryan’s drag knife and instructions should work. I would tape the vinyl perimeter down to a flat rigid surface.

I think the Roland style vinyl cutter(similar to what Ryan is selling) with a 60deg blade should work. I have just added one onto my MPCNC and still have a bit of fine tuning to do, but it seems to work well for vinyl. [20200819_192201] [20200819_192307]
