Tail Spring Stack clamp

Post by canav8 »

Ok, short topic. I got a new tail wheel spring stack from Univair for the 52 170B. It came with black paint that came off in my hands. I wish to repaint these springs individually to color match the aircraft. Does anyone know if there is a problem with the thickness of the stack when trying to resecure the spring stack clamp around the main and the second spring? What is the best way to protect these springs? Powdercoat would probably be to thick to put the clamp back on. Any advice? Thanks, Doug

Paint them with any quality polyurethane ... (Cessna used Dupont Imron in "Gull Gray").... The only significant wear occurs between the main spring and the one just above. I am presently testing my new springs using teflon tape between the mainspring and one just above (after slightly bevelling the lower trailing edge of the spring just above to avoid it's stressing the main spring or cutting the teflon tape.)

You should have no problem with painting them as far as spacing between or total spacing of the spring stack. Remember, polyurethand IS a plastic coating similar to powder coating (without the heat.)

You don't want to bake a spring......no matter how low the heat is....A good Polyurethane will work just fine......most auto shops will match your colour perfectly....even if faded, if you bring in a cover plate or something that has the colour you want..
