Yea I used a body filler.
Good catch baseballer. Had to move shop. Still set up out at my parents house, just in the garage instead of their "shed". There is a batting cage in the shed that has to be put up, because softball season is approaching and my sister will start working out here soon. So to be able to have room to build boxes and me not be in her way/her in mine, we did some moving around. It works out nicer actually, much smaller space, so I can afford to run the propane space heater now. In the old shop, it was pointless to turn it on, because it was so big.
If I remember tomorrow, when im finishing up on the box, Ill take some pics of the new setup.
