Cloth Cabinet
This I would do over if I had more room. It works fine but since the bulk of the material is cut on the diagonal it would work better if you have about 6 feet of table to pull the cloth out on. Keep the top at 36" high to match the bench. If you somehow have the room, allow 24" between the cutting bench and the workbench but in such a way as you can put in a filler piece to bridge the two tops and do longer cuts. Yah Chrissi, dream on. Just make sure it can close up nice and dust tight.

Make sure on the tabletop you put guide lines for alignment and cutting at 45
o etc. 
We also ended up making a covered roller holder for large rolls of peel ply above the cutting top. This stuff comes on 60" wide rolls so it would be a pain to put into the cloth cabinet.

The discussion of what tool is best to cut the different glass, kevlar, carbon and peel ply materials with comes up on a regular basis. We can safely say we tried them all (plans scissors, rotary wheel pizza cutter) and gave each a fair chance to prove itself but nothing came remotely close to the joy we get from the Dritz electric scissors.
Electric piranhas! 
Dritz electric scissors will cut through multiple layers of wet glass, if you go clockwise around a part with the upper scissor blade on top of the part you can wet trim with nearly zero overhang; no need to wait  for just the right moment to knife trim.

Wicks aircraft carries them as well as the spare cutter heads which are cheap. You can probably build the whole plane with one spare. 
We wrap them up in saran and then cover them in masking tape, then slit around the battery pack with a razor and cover the joint with a single wrap of tape. Clean up just the tips with a bit of acetone. The cutting edges have carbide inserts for long durability. They hold a charge for quite awhile and also come with a cheater cord in case you forget to charge them.

Cutting BID on the bias
Awhile ago someone asked us about this and I realized back when we first started how we spent an inordinate amount of time fussing with BID getting it set up and cut.
Every piece of BID you are going to use will be cut on the bias; setting the weave 45 deg with respect to the orthogonal axis of the part.

First thing we did was set up the cutting table with some guide lines like shown here at the right, click image for a larger picture.

There are side lines for the cloth width to lay it straight and at the end of the table lines at 30, 45, 60 degrees on both sides. Make these dark with a medium Sharpie and you will be able to see them through the cloth.

Next the BID cloth is pulled by both corners straight out till it reaches the end of the table. In the picture shown below it has already been aligned and cut on the 45 degree bias, click the image to see how the bias lines are clearly seen in the cloth.Click for a larger image

Rather then fuss too much trying to straighten the cloth out, make the first cut following the bias line of the cloth, then adjust the cloth straight down the sideline and then adjust the bias cut portion to the 45 degree line, now your cloth is straight. Depending on whether your cloth is on an original mill roll or cut to length and re-rolled by a supplier the bias lines could be from left to right or the reverse.


Measuring width of cut is perpendicular to the bias cut line, either make a small mark at the edge or a snip with you new Dritz scissors, then run them straight up the bias line of the weave, it will become obvious when you do it the first time. No fuss, no straightedge, no marking lines.

That's pretty much all there is to it unless you are cutting out a specific shape otherwise most of the time you keep the roll trimmed on the bias line.

Straight cuts of UNI we cut 1/2" wider, then peel out 1/4" of strands on each side to give it a selvage edge. This prevents loose strands from gumming everything up later.
