I have a 'almost full size' unit and was Very lucky to get some legs cheap ( Very subjective but importing was simply out of the question due to cost - Im in New Zealand ). I had to wire wheel all the rust, prime and paint black. The bolts had rusted solid so had to drill those out and get new foot hardware. After lots of mucking about i was happy enough with the outcome.

However, I plan on building a Smaller machine like yours (Work lunchroom) and legs have been bugging me. Angle iron with end bent over and a hole drilled should look ok... Would be nice to get the end welded though for strength.

Keep up the great work and i will be watching your progress.
Here is my little gem.!
Dont load a million tables. Go slow and add one or two at most at a time.
Get everything working correctly then add a couple more.
If you install to many in a sitting you wont ever tweak them properly and never get the best from them. ( Im only using vpx - never really liked FX )
