Has anyone had their gear leg get stuck in the attach bracket? We got the right leg in with a moderate amount of wiggle jiggle twist and turn effort, but now its wedged in tight. I think that some of the powder coat material chipped off and got between the leg and the bracket. We heated the bracket with a heat gun and we can turn (with a lot of effort) the leg about 10 degrees while pulling down on it. We've sprayed some silicone in the tube. This baby is really stuck. My next tactic might be a very large brass drift and a very heavy hammer to drive it out but the opportunity for doing serious damage scares the hell out of me. Any ideas??

I don't know if its any help but those legs fit with a pretty close tolerance. If just a little residual powder coat worked its way into the areas between the leg and bracket it made it even closer a fit.I don't think you would have any issues with the hammer and punch. If the leg rotates. I would do it but that's just me..I'm blessed with the midas touch!! A light tap will tell you how bad its stuck, if it moves down a little your probably OK...Rick S.

DId you put any lubricant on the two parts before you slid it in. Vasoline would be a good idea. 
This issue is very important to me because I need to get my grear legs off in order to get the plane out of the basement C so I am very worried about putting them on in the first place. This is my next step.
You might need to try cold C nitrogen or dry ice C before banging on it.

Liquid nitrogen on the leg shaft. Shrink tube heat gun on the mount, set to 975 degrees until a handheld IR thermometer confirms even heating. Don't use force, use physics.

You can use a common thermos to capture the liquid nitrogen from wide range of easily available sources.

You might try Silkroil from Kano Laboratories. I have been amazed at what it will loosen. www.Kanolabs.com. No affiliation. About $10

The leg, she is stuck no more! Today we sprayed some Aero Kroil on the stubborn right gear leg bracket and packed the leg in ice. We let that set for about 10 minutes and just before adding some heat to the bracket we gave it a try and it rotated quite freely so we pulled as we twisted and it came out in about 1 minute. Last Friday we worked for about an hour to get it the first half way out. The differences were that on Friday we applied heat and cold (as appropriate) to expand the outer and shrink the inner parts, and we lubricated with silicone instead of penetrating oil. It was the oil that made all the difference, so much so that we didn't need the heat. Physics and chemistry won out over force once again. - OH that was one other difference: Today we had a huge double jack standing next to the fuse in plain sight, but we never had to swing it.
