I will have to look back into that. The chassis is out away right now as it’s the only one I did and the tank is not built yet.
I'm thinking you will have to. So yeah, keep that in mind if you go to assemble the tank eventually and are wondering why your track is sitting kinda funky.
But otherwise what I'm doing is basically same as you. Drill it out and put 2 bearings in each wheel. Except you drilled all the way through and secured everything with glue. I'm just gonna leave the front bearing seat as it is and just use a Mato bearing in there. Then drill a pocket from the back, not quite all the way through to fit another Mato bearing in there. Leaving a small ledge sandwiched in the middle between the inner and outer bearing to secure the wheel to them. Basically exactly like the Taigen wheel was originally designed just narrower after shaving back the center of the wheel.
Your way is a bit simpler because you just drill a single new hole for both bearings to sit in so you know they will both be aligned with each other. I'm drilling a separate new pocket for the inside bearing that has to line up with the existing pocket for the outside bearing so that both bearings end up sitting centered relative to eachother so the wheel doesn't end up cockeyed or wobbling when spinning. I don't have a lathe to make sure they are lined up so I ordered a counterbore bit to be able to do it on my drill press. Atleast that's the plan, just waiting on the bit to arrive.
