Lookin good man! Those chains are nice and beefy. I made a set out of jewelry chain for my TL-01 copy, but the jewelry chain rusted and didn't hold up very well. Had to make quite a few repairs last year. lol Those are a much better deal. That motor sleeve is a neat idea, just as long as the vent lets enough heat out, but you'll also have the winter cold temps on your side to help a little. Nice work!
