Re: Jack for Tcraft

Here's yet another jack design. I made this one out of scraps I had around the shop.
The screw is a 1/2" carrage bolt with the head cut off. Welded on top of the screw is a saddle, section of 1" tube, that fits the tiebar knuckle. The saddle is welded on at an angle to mimic the tail-on-ground angle of the main gear. There's a piece of bicycle innertube glued on top of the saddle to cushion its contact. The main body is just a short piece of 3/4" tube with 4 washers welded on. And the legs are aluminum angle with more of that bicycle innertube glued on the bottom.
The jack will easily lift a wheel one or two inches off the ground, and it can handle up to 3" of tire flatness. It's actuated by turning that 1/2" nut.

And following the Berle Dictum ("make it small enough and light enough to take along in the plane"), it folds up into a 2 1/2" X 2 1/2" X 10" package that weighs 350g. (about 12 oz.)
