So I build engines on the side, more specifically the 4g63 and Honda Variants. I took it upon myself to try to mill the head and the deck of the block. The issues I have I believe are related to rigidity. The iron block actually came out perfect. I’m having more issues with the head. I think it may be due to the fact that I dont have the proper Fixture for it and it’s rocking. If you look at the surface finish it looks scalloped. I’m looking for a mirror finish. Ive tried brazed on tooling and indexible tooling. Maybe hss ? What’s the best for aluminum ? What are guys doing to add rigidity to their mills ? This is a Mighty comet just over 2000lbs. I was thinking about adding sandbags to the base? I’m even considering bolting it to the concrete
