Guess it would be simpler to just buy the powder. It is available online (ebay e.g) for cheap prices that do not justify the hassle of diy....except maybe for satisfying ones curiosity.


Trying to powder plastic sounds like too much hassle and grinding plastics is impossible to do by hand.

Either way, it was just something off the top of my head.

I just picked up the lathe from the shipping dock. I thought I would be able to move it around in the box more, but its wayyy too heavy. Thankfully I have a largish engine hoist that will do the trick getting it out of the uhaul.

Now that the offer of teflon has been made loptr will evaporate.


Poof!

Nope, still here. I was pricing some the other day. It's not expensive, so I'm not sure what the issue is. I was looking at about 6ft round stock for ~$40-50. A number of adapters and parts can be made from that.

The metal for turning will be a lot more available because I can get it nearby with steel being $0.20/lb.

If you are interested in ptfe alone, I am sure that I can also sell my turning. I know that ptfe powder has usage in energetics.

It takes a few weeks for the curse to take effect.
Let's see if you are still here in 3weeks.

Alright, the lathe is in the garage. Not yet on the its base, and that's because I have grossly underestimated how difficult 1000 lbs is to handle, not to mention trying to roll it across an exposed aggregate driveway. I was about to pass out when a neighbor stopped by and asked if they could help. Lol!

Tomorrow I will be rearranging the garage to make room, and the chemical cabinets will be getting a dedusting and moved to make way. Also, I will be taking an inventory of the lathe tooling I purchased to make sure I dont need any other tools for this work, and then it's off to place an order doe the ptfe.

I plan to make one of the adapters in this thread and then give it to someone on the forum for a review. You must actually review the item! Pics, video, or youtube will be expected. I am a perfectionist, so only a pretty decent or higher quality item will be sent out.
