I've been learning to TIG weld and one of the tricky parts to master is feeding the filler rod with my non-dominant hand.  It's been a while since I've done the challenge, so I thought I'd see what I could rustle up in way of an automatic rod feeder using just components from the TechShop bin wall.

Step 1: Raid the Bin Wall

For you non-TechShop members, the bin wall is a library of broken junk, odds and ends, and random components donated by and available to general use.  The Bin Wall Challenge, hereby designated, is to see what you can jury rig together without resorting to outside sources.
<p>As an experienced welder of all processes I see this as total waste of time and effort. But, don't beleive me, just ask any welder. </p>
<p>im so confused what does this do?</p>
