Same as above with a few exceptions -

I sheet both sides at the same time. Not really hard to do and keep straight. One trick is to put building pins (the T pins you use) through the foam shuck, into the balsa and into the core). This keeps the sheeting from sliding around on you. As for misting the cores/wood. This is necessary in dry climates - i.e. Arizona, Nevada, utah, etc. OR in the north during the winter when the heat is runnig most of the time. Since you live in a very humid climate (Seattle), you do not need to mist the cores or wood.

What size plane are you doing? I just finished up a 40% Edge. I used about 400-500 lbs on each wing panel. Be sure that the base board and top board are flat. many building surfaces will bend under 500 lbs of weight. Even the floor in your basement or garage may have a slight curve to it so double check. I have two pieces of slate that I got from a pool table repair guy. They have chips out of them so they are useless for pool tables, but are great for sheting wings. perfectly flat, strong, and HEAVY. My bottom peice is thick and weighs about 250lbs. My top piece is only about 3/4" thing and weighs around 100 - 125lbs. Total cost for the two pieces was around $75. For weights, I used the slates, plus weights from an exercise set, plus I got some lead steel disks which are considered waste from a local manufacturing company. I have an engineering friend who is into large rC and got them for me for free. You can also use concrete pavers, sand bags (Play sand is around $3 for 50lbs), or anything else you can find. Leave the weights on a min. of 4-6 hrs. Overnight is better - a full day is overkill and wasting time.

I like the polyurethane glue (I use Pro-Bond found at home Depot and other hardware stores - Gorilla Gule is similar) better than epoxy because of the foaming described above. I am lazy and hate edge glueing sheets! Vacuum Bagging is nice, but unless you have someone who has done a few to show you how, I would avoid it (plus you are looking at around $300 in equipment). If you vacuum bag, count on using epoxy. polyurethane glue WILL work, but drying time goes up to more like 24-36hrs.
