the brass ones would be easy to make something to form them i agree
I just sent him a text to see if he can grab a picture of the tool that they use to form them.
could use a grommet hole punch Attachment 7092 I have a matco gasketAttachment 7093 making set it would work good
As he described it to me, its a machined steel block with a round steel form. You place the brass disc in the block, sit the form on the top and smack it with a hammer. It forms the "cup" and trims off the excess material. These screens are pretty sturdy. I'm not sure one of those punches could make its way through the material these particular screens are made from.
Is it just the addition of the screen? I thought there were differences underneath, more/finer holes for the argon, etc.
The screens are finer than normal screen and $1.75 for a gas lens is much easier than cobbling something up. ;)Quote:

I've never used a setup like that but I think after the gas leaves the lens it would collimate against the ceramic cup so a screen at the end would difuse the column.Quote:

What kind of scotchbrite is he using? A quick google and it looks like 3m is using scotchbrite for a whole line of products. If someone uses scotchbrite closer to the arc, do they even need a gas lens collet body? Looks like the close the diffuser to the arc, the better it works.Quote:

Any good general hardware store will have several grades of plain scotch brite pads about 1/4" thick. I think there are plain consumer pads, but most are bonded to sponges or plastic handles and are not what you are after.Quote:

But anything even close to that will work as you are not using it for it's abrasive qualities.
He never specifies, but he talks about cleaning aluminum with a scotch brite pad and then talks about cutting a piece of scotch brite pad to use as a diffuser. He uses it on mig guns as well, reducing gas usage by 5 cfm.Quote:
