I’ve used carpet tape, worked but $ added up.
Diy double sided tape, worked better but time added up, and tape is getting pricey.
Clamps work well as long as your not doing a cutout.
This is my go to now for anything i can leave a tab or 2 in. Pins are fast and cheap.
I use the gel tape quite a bit I get it from the dollar store. It’s thick tho so you have to pay attention and it can also give you depth inconsistencies if you using say a bevel bit.
Here is some of me using it on some Eva foam. This was a bit of a task as the original backing was too slippery for tape to stick so I had to transfer that off and put a paper backing on. Some of the clamps ppl have are very cool as well I really need to look at adding those in.
It’s Eva marine foam flooring. 2mm grey ontop and 3mm black under. It comes in a lot of sizes. I am hopefully about to try doing some peanut butter brown and black in a couple mins. And thanks it’s a design I did.
It was a cheap 1/4” router v bit. That worked best for me. And my router was set at 5 and iirc I think it was about 14mm/s. A finishing pass is really what makes it nice. A couple spots I used a soldering iron. That was mostly for my pocketing as I had a tram issue.
I am doing more on Monday and I will post it and take note of feeds and speed.
What are you running your step over at? I am sure in that material it can handle a lot, but backing that off will probably get you a much cleaner finish, even more so with tram issues.
I am not too sure, I would have to look back again. Thanks for input makes sense I should have had it tighter. It kinda was nice on the feet tho for some grip. Next time I do it I will tune it in a bit better.
