I am currently tooling up to make some glass blowing lathes. My 1970 glass lathe used a box way with a cast iron tail stock. My current plan is to use mounted linear rails, the linear rails i ordered came with the bearing slides and they are an aluminum housing with a plastic insert with ball bearings. My concern is the radiant heat from the glassblowing process to melt the plastic so i have two options with step up to the more expensive stainless bearing inserts or use somethin like an oil impregnated bronze bushing. The reason for using the linear rails and bushing is that down the road they can be replaced if/when damaged. These are not high precision .0001 type tools as the glass we use are out of round or tollerance lucky if the tubes are within 5-8 thou of eachother. Any advice on the bushing over higher end bearing would be great.
