10' x 5' Plasma table design

[Kerryfisher]

Hello all, my name is Sean I live in Kerry, Ireland.

I would be pleased to hear your views of the design so far.

I have spent a lot of time studying many builds on different sites with some fantastic inspiration from many designs, this is what I have ended up designing.

It's a bolt together 2 sides and 4 crossmembers with the rail mounts bolted as well.

I might have gone for the all welded design but I think I might have bother keeping it all true, plus being on my own the weight might be a factor as well.

I have the Candcnc bladerunner 4 motor kit on its way over and I have the Powermax 45 with a machine torch.

I doubt I will be loading anything bigger than 8x4 1/4'' sheets.

The plan is to use 120 x 80 x 5 for the rails, the idea is to use 10mm flat slid down the inside to bolt into to allow a bit of clearance on the rail for adjustment, if I don't get them perfectly upright I can add adjusters as in the pic.

The rest of the box section is 60 x 60 probably go for 3mm wall?
Bolting the sides with 3 x 10mm (welding nuts inside the tube before assembly of the cross members)

I have made the tray slope towards the centre from either end, I know it makes the slat supports a bit more tricky but it should drain away fine with a cross break in the centre part, had to go that way as well with using a bolt together design other than leave it flat with no slope.

Tray and tank 2mm mild steel.

The plan is to use 25mm hiwin rails and rack/pinion drive, hoping to go for a unsprung pinion drive.

I still haven't finished the gantry design yet, but thinking of using 70mm x 70mm x 3mm steel.

Thanks for now, looking forward to starting the build after many days of staring at the screen.














With some nice grub screws rather than the bolts.
