I’m asking this question here for two reasons the first is that it’s two rail (On30) the second is I find this side of the forum to be pretty well mechanically inclined. Ultimately, I will post this over on the modelers thread on the three rail forum. My question is in the assembly of these trucks. I find you need a third or fourth hand to really make this happen. However, I’ve come up with a way that seems to work reasonably well, the pictures should explain below. I would like to know if somebody has a better method or a jig of some sort to hold the wheel sets and the truck side frames in place while you set the bolster from the top. I used a combination of set up blocks to hold things in place while I assembled the trucks.
