Masking update

I've been doing a bunch of cutting on the 1/8" birch from WoodCraft for a design I'm perfecting, and after trying the plastic masking film someone recommended, I decided that paper film would be better. Well lo and behold a friend just happened to have two large 12" rolls of paper transfer tape for transferring sticky-back nylon laying around his shop that I happened across. It's labeled Masking Angel Tape. It's the same cream color as standard masking tape and has a medium tack I'd guess. I tried it out today and while it masked the char well, it also left behind a nasty residue from the burnt glue at the edges which doesn't come off easily. So... strike two. Plain old blue painters tape has been working the best by a long shot, so I picked up a 3-inch roll and will be using that from now on. Stick with what works. I've seen on some 3D printer groups (they use it to print on) that they bulk order it in larger rolls ... 6 inches or more... so that might be the way to go for larger cuts in the future.

I've updated the materials database with the above mentioned birch... and have some 1/8" bamboo ply on the way from Not cheap at $8.56 per square foot plus shipping, but I used the $20 gift card that came with the laser to buy it, so we'll see if it's worth the money. It can be had for cheaper in much larger sheets.

Masking no go

I tried the masking film I ordered from SignWarehouse on the 1/4" Birch Plywood and it mostly doesn't work. It's not tacky enough and as it melts it peels back away from the cut so the board still gets charred. It works where it sticks it just doesn't stick around the entire edge. Bummer... that was a waste of cash. Will have to find something else. [UPDATE] After a quick search on SawMillCreek forums I realized ordering plastic film as a mask was one of the least brilliant purchases I've made in a while. Don't know why I didn't think about it... I saw someone else recommend it on Thingiverse and just blindly ordered. Turns out plastic melts! Shocker. I've tried masking with blue painters tape before and it worked great. So now I need to source some PAPER transfer tape... or just buy a bunch of 3" blue painters tape. Hmm.
