Drilling and taping M3 holes for 15mm rails

[Tom J]

Drilling holes - M3x16mm socket bolts. They tall enough to use entire thread depth and goes inside 25mm wide profile. There will be only 4mm hole left outside to insert the allen key:)

[Tom J]

Errors are inevitable - forgot to cut the slot for the belt - grrr.
Had to grind and mill 20mm slot - wasted my precious time.

[Tom J]

Base for legs: 2mm profile (2.5 before planing) 5mm plate plus m8 nut, so total of 15mm thread depth for vibro-damping stands.

Frame almost done.
Y motor bracket need to be welded in place
Detecting plate for Home and Limit - this will have slots, so can be adjusted accordingly - should be done before was welded - now need to buy angle drill. I should finish design to last bolt first before starting fabrication - always do the same mistake - just not patient enough.

Had to shortened the RM1605 ballscrew by 14mm.

My tip for turning exact diameter is to leave 0.1mm and use sand paper on the end to get nice fit to bearings.

Looking good Tom keep it up can't wait to see it Rattle n Roll. .

[Tom J]

Planing base for ballscrew - base is 60x5 mild still (as we know is far from flat, unlike cold rolled - bright steel)
As always got some distortion after welding.

Updated design - new colour, few minor changes in Z plate


Welding the gantry - was waiting for another precision angle from Amazon - Happy with the result 0.5 mm off i checked against one side - spot on from other side. When all will be welded together (base for rails, ribs, etc) than will machine the base to have straight angle. I will leave the rails on the block, as this will be reference surface to the angle plate when fix to the mill - confusing now, but will show the picture soon.
Meantime - how I achieved accuracy before welding - spot how I use the straight angles (Gantry legs, than against table and Base for X axle) All surfaces has been planed each time I weld something - this was my error, should weld everything first than machine to avoid distortion.
