Machine Skates

October 24, 2021

These skates were started in a panic the last time I moved my shop. I had less than a month to find a new shop and move in San Francisco. This is not an easy task. Needless to say I did not finish them in time for the move.

I generally make shop items from whatever I have in the shop. It this case, what I had in the shop changed over the years. Honestly, if I started this now I would have just bought some skates from Amazon. The price has really come down and there are a lot more options. But I started this and I wanted to finish it.

My design involved a c-channel and some cheap bearings from ebay. I weld some mounts onto the c-channel to squeeze the inner races of the bearings. This properly distributes the load. They are smooth as butter. It has been several years and I cannot remember the actual forces these can hold. I sure it somewhere around a shit ton.

Unfortunately I made the axles from pretty hard steel. I am not sure what steel it was as I made these serval years ago. They were difficult to tap. I did not want to break a tap so I tapped them by hand.

Tacking the handle loop. The rods were some old grounding rod, hence the copper plating.

The angle on the handle looks good!

I painted it antique white with accents of anti seize. I am ready to move again!
