To fulfill my Clever Quota for the week...
I have been trying to figure out how to use spoolgun spools for short pieces of small diameter wire for TIG welding.
After buying a real wire straightener off of eBay I finally figured it out.
The photo Album is here
The wire guides are 1/2" bolts with 10-32 nuts TIG brazed off center. A 1/4" x 10-32 screw is loctited into the nut. You rotate each guide to adjust the amount of deflection you need to end up with a straight wire. The final guide is a short piece of 3/8" square stock with a 1/16" hole in it.
The eye screw keeps the wire feeding into the guides. The spool itself is kept from free spinning by tensioning the axle bolt with a nylock nut against a lock washer. There is also a nylon washer between the the spool and the wood to reduce friction.
My rack has 5 spools.
0.035" 4043 Aluminum
0.047" 4043 Aluminum
0.035" Silicon Bronze
0.024" 308L SS
0.024" ER70S-2 steel
This will go on top of my TIG machine. Just grab the end of the wire with pliers and pull out a short piece, snip and there you have it.
Let me know if the album is not accessible.
