What kind of clearance between axle and wheel bore should I have to locktight 5 guage wheels to the axles? This is for my Simplex.

Ron, I don't know what "5 guage wheels" are, but you want a slight clearance fit (call it LC-5 class fit) for loctite-type adhesives to work. They need to expand as they cure -- so .002/.001 diametral clearance is about right for most things less than .50 inches in diameter. Machinery's Handbook has a pretty good section on fits.

Thanks for the response Lew. They are Model Locomotive wheels. I think it means the distance between the rails is 5in. The axles are .670 dia.
I was using the term "locktight" generically as I seem to be able to find the permatex brand as sold by NAPA easier than the real Locktight brand. I have some permatex that is for sleeves and bearings and is supposed to be permenant after it has set up. Has anyone got any experience with this?

Ron I used loctite on my loco 3 1/2" about 0.001" to 0.002 is fine. Use to have a lot to do with loctite at work (now henkel) the rep said they fix full size loco wheels with loctite using an interference fit.

Thanks Stew, thats good to know. If it works for the bigguns it'll work for us.
