The ballscrew will have a mount either end to bolt into just laid it roughly where it's going to go, Hiwin's bolted on finally need to cut them down.
This will be the gantry (Has clone Hiwin's on)
3 individual pieces 2 * 4545 and 1*9045 will drill 5 holes through the 4545 and bolt using T nuts to the 9045 to reduce flex.
The Hiwin problem anyone who's used 15mm Hiwin's and a 1605 ballscrew knows this problem lol, it doesn't affect my Y axis because the ballscrews are at right angles to the Hiwin's but the gantry and Z axis both had this problem which I solved with a combination of spacers and recesses.
Aluminium extrusion is strong but not that strong lol
Heavy duty 6045 I found under the mess when the shelf collapsed this will get cut down for leg supports now.
I still have 2 pieces of the SBR left with bearing this will be the basis for my positive pressure vac former ballscrew driven naturally.
I can say from personal experience DO NOT BUY EVOLUTION TABLE SAW it's total shit!Last edited by Desertboy; 19-08-2017 at 12:50 PM.
