What is the Total Cost of Conversion (Excluding the Mill)

[Muzzer]

dazp - when you say "AC" bearings, what do you mean by that - are you referring to the seals? To minimise the backlash you presumably used back to back or double row bearings?

Angular Contact.

I made my own bearing blocks (23mm thick with 2mm wide internal ridge) from 1 inch alloy stock.
Fitted 2x 7201-B-2RS in each for use on 1605 screws. Back to Back.
Adjusted preload on DFU with bits of 0.01mm thick alu foil between the nuts.

These are the screws and seller I used on x,y,z

(I think I got a slightly shorter 700mm one for z)
Haven't tried their 2005 ones. My 25 mill was fine with all 1605.
