Rkeller, I fully agree! I think I just jumped the gun. Got to excited to use my new 'toy' and didn't think about how 'wiggly' the jigsaw can get.
*Update*
Worked on rolling the BT today with a little help from my dad. He was very interested in the process, and I was glad to learn something new with him. We'll find out in a few hours whether or not I did everything correctly, but it was a great experience. More work than I expected, for sure.
Details:
I am using 8 Harness Satin Weave 'glass. I used a piece ~30 in. long by 32 in. wide (giving plenty of extra room in BT length for a bit of first timers forgiveness). I used a little over 1 set of 3 to 1 pumps of US Composites Medium Epoxy/Hardener. As of yet I do not have a digital scale to weigh items, so I used 6 pumps of epoxy to 2 pumps of hardener, and ended up with just under half of the amount mixed left in my butter bowl.
I laid everything I would need out on a side table, and covered a small portable bench with butcher paper (which is a witch to tape down, btw!). Using Jon Cokers method, I laid the 'glass on top of the bench and poured a portion of mixed epoxy onto it. I spread it around the cloth with an old Subway gift card and removed as much excess as I could (I checked by squeegeeing in different directions, looking for lines of epoxy that had not soaked in). After the cloth was saturated the glass was no longer shiny and white and had the same dull silver color throughout. Had some air bubbles but I got those out as well before placing my parchment covered mandrel on the fabric.
The rest is pretty much history. I left a portion of the butcher paper so that it wasn't taped to the bench so I could use it to help lift the edge of the cloth to the mandrel. Stretched and straightened the cloth as I went and kept a constant tension. Smoothed my hands over the cloth to continue to work the epoxy into the 'glass. I chose to do 3 wraps of cloth, and 3 wraps of porous teflon coated release film after. I set the tube on end and let it cure for 8 hours before taking the film off and as of right now am very impressed with how it turned out. It is a tad bit sticky yet, but our temps have dipped into the 60's so I suspect that to be the culprit.
