I am restoring a Wyco 993 concrete vibrator. It was missing a cover,
shaft, and switch. I had a matching switch in my parts pile. I bought
this vibrator as a pile of parts from an auction (along with 5 working
vibrators and a lot of shafts and other parts). It was broken due to
physical impact (plastic cover broken). It is easy work, got the cover
on ebay, have other parts etc. Vibrator runs fine after I put on the
switch. No complaints.
My only problem is that in a certain place, they use 1/4-20 nylon
plastic bolts, probably for electrical insulation purposes. The bolts
are broken, they broke off as the cover, that they held, was hit and
broke off. My question is how to remove their remains from holes.
