Fellow Kolbers,



A few months ago, the check valve in my cheap hydraulic jack failed so I put my thinking cap on and designed a cheap, light-weight (even portable for field repairs) quick to use axle jack for Kolbs or other aircraft with axles that extend away from the  wheel a bit. I've attached an image of the drawing/sketch that show the working dimensions. If anyone is interested in more details, I'll be happy to provide them, including the build dimensions and materials I used. I plan to make a short video of it in operation on my Slingshot and post that too.

Thom,

I have nothing on your post that will open to show a sketch.  It may be my computer or browser (firefox).

ss568,



go to the KOLB Forum website and you should be able to see it there. it is a .tif file type.

For those who can't open a tif file, attached is a jpg version.

Thanks , George. I thought about posting it as jpg but it was another step and assumed all browsers could display tif files. Assumptions frequently are false.

why not invent a twofer gadget:   does both an axle and lifts the tailwheel.

BB,



The need or a "twofer" has not yet arisen in my hangar so I've not rigged one .



Just before flying out to your place this morning, BB, I made a short video of the axle jack at work. Note the little triangular piece I cut off of the 2x8 corner is used as a security chock, if leaving the jacked airplane for awhile with the wheel off. The over center is enough to keep it locked in place, unless someone gives the Kolb a big push. This little triangular piece prevents it from coming back over center and falling, even if someone tried to knock it off the jack.



To jack higher or a Kolb with larger diameter tires, just place a 2x6 under the jack and it will raise the axle another 1.5" higher. I used the handle from my dysfunctional hydraulic jack but one could use a hardwood dowel. 



I know this is simple and nobody asked for this but I've found it to be quite useful. Worth what you paid for it, as at least one Kolber often sez.

You will notice in the video that the 3" dia. wheels on the jack do not roll much. This is because the asphalt surface  in my hangar is very rough and not much better than course gravel stuck together with a little tar.
