Making bogey mounts

Before I can have a rolling chassis, I  need to make the frame mounts for the 3 bolts that attach the bogies to the frame.

Here are the mount  pieces:

They will be welded to the frame like this:

Bolting the bogies on, to hold the mount pieces in place while I weld them on:

Here they are, all of one side bolted on, ready to be welded… they really make this chassis start to look like something.

Once the mounts are all welded in place, I will remove the bogies, add the spacers, bogey arms, springs, upper rollers (which support the track), and finally the wheels.  I am currently using 1/4″ bolts.. I’m a little worried they will be weak, so I might drill them out and replace them with 3/8″ or even 1/2″ bolts.  I could also just replace the bottom center bolt making it the load bearing bolt.  We shall see.

One other note… the wood hull will also need to have these same holes drilled, so the bogies can mount on the outside of the hull.
