It's Rohr wsme-250

Not sure if this the right place for this but here goes

I bought a cheap Chinese tig foot pedal for my tig welder the first time I tried it it was working backwards so I changed 2 wires around and now it works the correct way round

However when the pedal is fully depressed I only get a max of 100 amps and the max of the machine is 250 amps do I need a higher or lower resistance pot?

Thank you all now just need to order the aluminium and make patterns

Hi all I would like to attempt to make a seat base for my triton I would like to use aluminium but what grade would be best for forming the seat I would want to bend and weld the pieces together any help appreciated

Woops

Hi Tim yes it is for steam I have several small steam engines ie Stuart beam etc I've made several small steam engines just simple stuff

But would now like to make a bioler to run about 60 80 psi vertical about 100mm dia and about 250 high gas heated

Hi all I would like to make a simple vertical bioler can anyone point me to where I could get some free plans

And what would be the best solder to use

Couple more questions

What pressure should the boiler run at

And what should I use to seal the glands on steam chest and cylinder

Many thanks

Hi all ran it up on steam today for first time lots of steam leaks bad one around the glass tube on the boiler what should I do to seal the leaks dont want to break anything

I've recently acquired a stuart beam engine dont know much about them it's been sat in a garage for a few years I've had it running on compressed air for a while there is a very light tapping that seems to be coming from the eccentric there is a tiny bit of play ?

Also should there be compression at both ends of the cylinder if I open the top drain the engine will carry on running if I open the bottom drain it will stop

Any help appreciated as I am new to live steam

Thanks all it was as said adjuster behind

Ah this maybe the problem will have another look tomorrow

The screws are slotted will try some heat and see if I can get them out

6inch abwood machine vice it's got some play in it but I cantc shift the gib screws any advice on this one

It looks like a dp16 14.5 pa still not sure how many teeth yet as I can't all the bits

So if someone can confirm that would be great

While drilling a large hole in back gear the small gear broke into pieces it looks like it's been broken before and locktited n the shaft

My question is how many teeth should there be and what is the pitch is what cutter would I need to make another
