Well after the terrible news about the landing incident I decided to check thetoe-in or out on my project I'm trying to complete.as usual I find more than Iwanted to. the Cub gear I got from D.J. looks really nice with the white powdercoat finish.I know I had to modify the mounting holes in a couple of locationswhen I mounted it.but figured all was well. good thing I went back and checked.there seems to be almost a full 3/8" toe in from the front of the tire tothe rear.that is what I call a pretty significant amount -especially when Ihave been told that if anything it is better to have a slight toe out on conventionalgear.not sure whether I'll have to use heat or just what to adjust thisbut if anybody has advice concerning lining up Cub style gear I'd appreciateit.I'm glad I found it now rather than later. I am doing the check with the tailup in near normal flight attitude.RaymondRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

Can't help with a Cub gear, but for a Cessna 180 or 185, at flight weight, there's supposed to be zero toe-in or toe-out.I'd think that would be a good starting place.Mechanics use grease-plates for this to account for gear flex. You can use plastic trash bags instead of grease. Get a couple large aluminum plates (1/8" thick works okay) and either put a trash bag between them or a handful of grease, and then roll the main wheel tire on to them. The upper plate will side around a bit and that'll change the indication of toe-in somewhat.As memory goes, on a 185, the maximum toe-in was 1/8" across the wheel rim itself, not the whole tire. But I could be wrong about that - the zero toe-in at flight weight is a reliable data point.David Paule> >> Well after the terrible news about the landing incident I decided to check > the toe-in or out on my project I'm trying to complete.as usual I find > more than I wanted to. the Cub gear I got from D.J. looks really nice with > the white powder coat finish.I know I had to modify the mounting holes in > a couple of locations when I mounted it.but figured all was well. good > thing I went back and checked. there seems to be almost a full 3/8" toe in > from the front of the tire to the rear.that is what I call a pretty > significant amount -especially when I have been told that if anything it > is better to have a slight toe out on conventional gear.not sure whether > I'll have to use heat or just what to adjust this but if anybody has > advice concerning lining up Cub style gear I'd appreciate it.I'm glad I > found it now rather than later.
