--I'm going to build a rotary surface that's being turned by one of
those worm drive windshield wiper motors. What I need are some supports for the surface so that it won't sag when there's a load on it. What I'm looking for are those things that have a short threaded rod with a clevis that holds a bearing on one end. I could make 'em but I'm thinking they're probably available from someone's catalog if I only knew what they were called. Anyone got an answer? --Thx, -- "Steamboat Ed" Haas : Steel, Stainless, Titanium: Hacking the Trailing Edge! : Guaranteed Uncertified Welding! www.nmpproducts.com ---Decks a-wash in a sea of words--- |

I need one with the bearing turned 90 degrees, so that the load is pushing along the long axis of the shank.. Hmm, The older Ford Escorts with the 1.9 engine use roller cam lifters. I've got a pair floating around here somewhere but can't locate at the moment. IIRC, they were around $16-18 each. A block with a bored hole, side slot, and clamp screw would hold them. If your design offers axial access, a separate adjustment screw and lock nut would allow adjustment and prevent it from pushing away from any load. Hope that explanation is clear... Jon |

A love of truth and a veneration of virtue. These amiable passions, are the latent spark.
