In the market for a new tool rest. Was wondering if anyone had any experience with nova Teknatool tool rest? The only reason I am considering the nova tool rest is its changeable post. Would prefer a robust tool rest. In the near future I plan on upgrading my jet 1221 which has a 5/8 tool rest post. I’m sick of flattening my tool rest. New lathe will more than likely have a 1 inch tool rest post. I believe I will be able to change the post out without changing all of the tool rest. It looks to me like the nova tool rest has hardened steel instead of cast iron. One of my concerns is the threaded tool rest post may loosen and spin the tool rest while turning. Any help would be appreciated. Thank you.
