I am new to welding - been at it about a year now. Started off with stick inverter, then bought a TIG torch and bottle of Argon to go with it. I...

It is important to connect all the shields to a star point at the control box. Including grounding the router frame. Only ground one end of the...

Hi again, Here are the photos I.ve promised 4 weeks ago. It is a 5/5 machine (1.5m/1.5m) made of 2.3 inches (6cm) steel tubing, and aluminium...

Don't know anything about the concentrator approach, but that kind of price could get you something like this, with enough left over for a regulator...

Great design and in-depth write up for us newbies Many thanks for sharing your hard work with others regards Mike

Thanks Neale, That has definitely convinced me to use steel as I too weld. Your design is great too, do you have the measurements or the cad...

Problem solved:barbershop_quartet_ There was no safety earth on the chassis so after adding that and an EMI filter all is well. So now I can get on...

Howdy, no problem Mike. If you're only plasma cutting, an aluminum extrusion machine is most likely plenty strong enough since there are no real...

Dear John Could you advise approximately how much you want for the machine and does the price include the software dongle? If you want to email...

A smaller Harrison 600 has popped on another forum. Worth looking at, even for some manual milling (and perhaps CNC conversion)?

Hi. What happened to the finished product? Got to the last page all exited and not a pic in sight... Cheers, Trevor.

Aluminum or steel box - your choice! My machine is all steel box section, welded, including the gantry (which is relatively uncommon). I also used a...

Well, so far it hasn't gone wrong!

Thanks Rob. Do you suggest I avoid steel plate completely ? What about steel box section ? Or just stick with aluminium plate and extrusion. ?...

Welcome Mike, I built my machine without doing any drawings just rough sketches. I used a pillar drill and a set of calipers, it was fairly accurate...

Hi Mate, Where are you based? Does it turn on ect? Thanks! (Edit - Not to worry! Saw you sold it on Ebay!) Alex

Thanks Clive. I use fusion360 but I'm really new to it. I have a design in process using some of the aluminium extrusion however after reading and...

Hi Mike and welcome to the forum. I have read your other post and see you are looking to build a machine. The usual advice is to say not to buy...

Sorry to jump onto this thread but I was looking at the same thing..... I was thinking of using c-beam with 4x2x1.5mm box section with welded ends...

And no thumbs:glee:

Heh - way ahead of me skipper - that's exactly what I'm trying to design at the moment... I have a whole heap of broken small diameter carbide...

Yes, nice. Technically that's engraving - printmakers get hot under the collar about the confusion! You can get a nice variation in the line width...

Cool tip - cheers John, will look into that. I've been reading up a bit on various techniques - I'm quite interested in having a go at generating...

Aha! Sorry I didn't appreciate that you had designed the screws to lift as well - that's a refinement that I don't think many presses have! Once...

Hi John, Hmm - that's an odd thing to throw in at this stage - it was fairly obvious from my earlier posts that I was going for a 'sprung...

Either, it depends on the jumper setting.

Well he's still got ten fingers and not too many scars, so he must be doing something right ! Cheers Andrew
