If you've ever been interested in the history of Zee Toys or Maisto over the course of the 80s, 90s and into the modern day, you should come over to the Hobbytalk Ask Me Anything with Chepp going live on Tuesday, September 21st and running until Thursday, September 23rd. Don't miss out! You can ask your questions here!
Twister is long out of business so they won't be able to check it out or replace any parts. Lathes usually don't have any problems unless they are used a ton and never cleaned. IF when you move the bit left to right and it feels gritty that's not good. Getting dirt or cuttings in the gimbles would be a problem. IF the blocks don't show wear from the armature then they should be good. The cutting bit if it's carbide should be sharpened or replaced probably every 10-20 cuts. If you have a micrometer make sure everything is straight with relation to the blocks, base, and gimbles.
I heard from a good source that Chris Dosick (sp) has a business where he lazar aligns our mini lathes. I like to have it done to my Hudy. Maybe between the two of us we can get a line on how to get in touch with him.
