When building my latest table I needed a torch floating head assembly, in the past I used "V" bearings and rail. Seller did not deliver, plan B print a new design of my own.
This is what I came up with it uses 8 MM linear bearings and rails bought from eBay (3-D printer parts). There are small holes that can be taped with a 10-32 thread for mounting to a plate and also hold the torch in place. the switch is a standard Micro with a roller but the roller is not required for this project. The bearings and shafts are push fit you could put a drop of super glue if you like.
