Metal Stuff / Re: Tig tungsten
« Last post by WeldingRod on December 10, 2018, 08:49:44 AM »Yep, that's it! I'm 99% sure mine isnt 3800 rpm. I put one in at work too, so I've run two of them. It's a brush motor, so you could drop the speed further by going to half wave rectification of phase control.
If there's interest I could publish my sliding table for it.

So I'll probably bore you to death with the fettling and machining over the next day or two
You can keep trying but we are made of tougher stuff here

Btw, if you have access to harbor fright saw grinders, buy one!!!! Put on the diamond wheel and revel in moderate speed grinding awesomeness. It does great on tungsten and carbide, and is slow enough for steel (really).
This one?

3800 rpm / 140W?
thank you,

« Last post by awemawson on December 10, 2018, 05:33:51 AM »I received two emails from Migatronic in Denmark this morning:
The first one said that as I wasn't a "B2B" customer (what ever that is!) that I couldn't use their 'Webshop' and sent a link to their dealer network map.
The second was a bit more helpful, said that they did have both the feed and pressure rollers in stock, and giving the number of their UK Parts Sales Manager in the Midlands. Ringing the (UK) number I ended up speaking to Denmark anyway
After a bit of chasing through the system the result is good - two rollers on the way to me by courier expected Thursday - not cheap but the welder doesn't owe me anything having given good service for many years - I got it second hand about eight years ago, but it was made in 1995 so 23 years old.

Today the postman brought me
THE BRONZE DRIVE DOGS
They look splendid as cast - obviously they will require a little machining, at least on the bore, but the actual teeth mesh beautifully with their opposite number on the machine.
I was surprised to be able to see the actual build lines from the 3D printer, as crisp as the original though more visible due to the colour.
So I'll probably bore you to death with the fettling and machining over the next day or two

If I understand correctly the vibration comes from having the fan out of balance by the insertion of the 2ba nut n bolt. With the fan bolted to the underside of the table balancing on the springs it seems to me to be a nice simple and low noise solution.
Glad I asked.
Thanks for the reply.
