Hi everyone,

I am restoring a Johnson Thunderbolt that's missing its square rubber feet.  Does anyone have a rubber foot substitution that you recommend or some spare rubber feet that I could purchase?  I am trying to make everything look original. 

Thank you and 73,
Tony W1TTL

This doesn't help you much but back about 4 years ago there was a guy on eBay selling repro exact feet.  I needed more recently and can't find him now!

What I found after a lot of looking is plastic corks at Home despot. They have them in all sizes.  I glued them on with the large end to the chassis. I think I used a hot glue gun to affix them?

They call them rubber stoppers and here is a link. Go to the hardware section and you'll find them in the pull out drawers with all the other misc items..

   Let me know what you think about this solution?

I went through this several years ago with my first T-Bolt. The original feet are no longer in production.
I opted for these shown below from Grainer, 5 for $10. They also sell a similar one, same diameter but not quite as high.

Those look nice Pete! I guess I should have come here first rather than looking at everything in HD?

Mine had round feet with I think #10 threaded screws, they looked original.
Make sure when you replace you put those screws back in so they dont stick up
on the rail. The screw head ought to be on the rail side. Otherwise a little thread portrudes
and makes it hard to slide the chassis in on the rails.

I put some fine oil on the rails to make it slide a little easier.
Also check out the IO group I made for the Johnson Linears,
someone there may have some.

I have a fair number of heavy transmitters, amplifiers, and receivers, and I rotate onto and off the ops bench fairly regularly, so having rubber feet that "grip the road" so to speak, are certainly not an asset, since they virtually prohibit moving the monsters around on the bench.   

I install self adhesive Felt pads to either replace the rubber feet on the bottom of the cabinet, or attach them on the underside of the rubber feet.   They are available in a variety of sizes and shapes and easily cut to size if needed.    These big heavy old BA's are certainly heavy enough that even with the felt pads they don't move without a fair amount of push being applied, but they move fairly easily so that positioning them on the bench doesn't require calling for reinforcements.

For future reference - McMaster-Carr sells a variety of "bumpers", also for use as equipment feet.
