Next task, the bearing blocks, just a little bit of
milling work, the aluminium profile was nearly perfect in size. The
seat of the bearing was drilled and grinded in the 4 jaw chuck it is a
H7 fit and the bearings will be fixed with a little drop of loctite 243.
As I mentioned before it turned
out that the drillings for the blocks were in the right place, the axle
turns without resistance :-)
