Been an avid reader of some of the projects on this forum but guess it's time to ask some questions.
I've been doing some consultancy work for a power electronics company in London recently and treated myself to an R-Tech P50HF (having played with a friend's P30C cutting off various bits of my 110). There were a number of reasons for going for the bigger one:
- It's bigger and therefore better
- Has a pilot arc and I'll probably see about building a CNC table for it.
- The tale below...
One of the clients of the company has had delivered to them a 12ft long, 2ft diameter, 20mm walled 'pipe'. He asked if they could see about cutting it in half to turn it into... - a barbecue
As I understand it the plan is to cut it in half length ways, presumably he'll then need some hydraulics to open it!
So I thought I'd draw on the collective wisdom of the forum and see if anyone had any neat tricks or tips they can think of. My current thoughts are to build up a jig that can be clamped, or even tack welded to the pipe to guide the torch. As I'm new at playing with the plasma (only had it a week) will the length of the pipe affect things - i.e. if I put the earth on one end I'll at some point be approximately 6ft away from it. Too tired to work out what the resistance drop over that would be at the moment. I plan on probably doing it in a few stages since it'll be pushing the machine fairly hard.
Not afraid to fabricate some tools if anyone has any bright ideas, got a decent collection of stuff in the shed including a lathe.
I guess I could have gone up to the 100A version but then I'm limited to using it nowhere useful (i.e. not at home ) since it's three phase. Power won't be an issue as they've recently had the supply upgraded to in excess of 200kW (3 phase 400A main feed now). Compressor wise my normal one should keep up but failing that I have a backup in the form of an engine driven one on my Defender .
So am I mad for attempting this... probably but it'll be fun.
