CNC Router V1.0 (For Cutting Multiple Materials)

Yet again, thank you for all the help! I think I may end up going for something like 60 x 40 x 3mm box section as this is within the capabilities of my welder and isn't too expensive.

If you can go with 4mm all the better for drilling a tapping. ..Clive

Hmm if I can get away with 100A/2.5mm electrodes then maybe. Although it is an added cost...

The rail I have takes M4 bolts so thats 4.28 threads for 3mm and 5.71 for 4mm... I think the rule is 1x the diameter?

Started work on the base...

Better just put some triangle plates on the front uprights and your sorted.

Still need to sort that gantry thou and put the bottom profile flat with vertical one above it.! . . . Hard to see from drawing but what size profile is it.?

[biketrialsdave]

3mm it is!

Yes, still a bit of work to do on the gantry (motor mounting etc). The profile is 80x40. If I can mount the motor on the outside of the gantry end plates then I was going to put another piece of horizontal profile in to enclose the back completely.

While I'm here, what brands of welding rods do you guys recommend? There's plenty of "Super 6" ones on Ebay (6013) for a good price?

Dave,

See screen shot, i had 5 mins spare. The red and green sections would fix to your side plates and then to each other, the profile is 80x80, the plate is 20mm, note the datum for the rails on the front plate.

Listen trust me it will be fine. One more added point My machine was mounted vertical for well over a year and other than hanging from the ceiling you couldn't put more stress on the bolts has they had all the weight of the gantry bearing down on them and they didn't even flinch. Go for it won't be problem.!
