Looks good! Garrie has been using radiant heat with good results. His method works without need for an oven.

Well, this is a good thread. Some vacuum mold, some can not. A lil' more interesting. Maybe garrie will give some tips snd pics.

Questions:
Which one would lay down in a female mold and drape form easier??? Look a my cf canopy, i can't vaccum. I use cf canopy mold as windows mold.

Cell cast acrylic is 69$ if in stock.
Polycarbonate is $60, iam gonna drive up and get a sheet. (4x6') much in stock @ 1/16" thick.

Do you know the optics of cell-cast vs polycarbonate???

My oven is also multitasking to cure my parts too at about 140 degrees.

OK, here is a video showing how I made the "lens" for the rear tail light of Rick Wianecki's velomobile

Scroll down on the next page to read how Rick installed the lens.

This is the way i will try except " I USE FEMALE MOLD" to hopefully find an optical seat down in mold for front windshield.

Blue felt to lay on mold/tool. I have second orange mold press part made like in vid.

Todd's canopies of ft. Laud fla. was a good friend,,,, here last summer to teach me a few things. Unfortunately he was killed in his plane bout 7 months ago. He basically said kiss! He was 325 degrees for 10 mins.

I noticed this guy uses 145 degrees for 25 mins. The poly or acrylic is layed on 100% piece of cotton. U see him straightening it out with metal tube in video.

What you could help me with is trimming!!!
