I placed an order with McMaster-Carr a year ago from Canada, and it was declined with the usual excuse, even though I used my company name. After reading one of the comments here, I tried again last week, and the order was shipped. Hopefully this means I am now one of their good customers, and I won't have problems in the future. Time will tell.
Xnaron, I have the required spacer shims, and two sets of bearings from VXB to do a bearing conversion. If you would be interested on working on a bearing conversion together, and doing two mills at the same time, I'll supply the shims, since I have 10 of each. Since we are both located in Edmonton, and seem to work on similar projects, I figured we might get along quite well, and it might be useful to have someone else to bounce ideas off of. Let me know if you are interested.
