Texas has been hit by a bit of cool air awhile ago, and we actually had to break our propane heater to warm things up (I know what you're thinking: In TEXAS?)
Next up is our work on the spar. The jig is finished, and I cut out all of the foam pieces and LWA aluminum pieces. I also sanded down the wing attach points on the urethane pieces.
Last but not least, we're finally getting around to getting weights to hold things in place while curing. We decided lead shot bags would be too expensive, so we chose sand. The sandbags are made from polypropylene bags (If you need some, contact me, we had to buy 1000) filled with sand. The bags are then closed up by use of a food storage machine. It's one of 'em fancy gadgets that suck the air out so food lasts longer in the freezer. Mom gets it when we're done. We've calculated that a 60 lb. bag of sand fills about 20 bags, so each bag is about 3 lb. We've already made around 40 in one night.
