To Mike Cuy, and any of the rest of you with brakes. I machined the 4130 1.5" OD straight axle today. I have cutthreads for spindle nuts and turned the bushing section to accept myconverted motorcycle wheels. I noticed that your pictures Mike, have a shaft protruding downthrough the bottom block. Is this bolt preventing axle rotation andacting as a travel limit? How is the bolt fastened to the axle and ifthis is what you are doing is it working out well? I guess what I'm asking is how do you stop the axle from rotating asthe brakes absorb the wheels torque? John Mc________________________________________________________________________________

Is this bolt preventing axle rotation andacting as a travel limit? John- Yes and yes. In addition to those two issues this shaftalso prevents the axle from moving left or right as you bump along the ground. Frank Pavliga had this happenearly on and every so often they would have to shove the axle back to it's proper position under thebungees. ***as a word of caution, no matter what design you end up using to get the job done, a good thing to do is loopand nicopress a length of cable around each axle/gear leg so that if your bungee lets loose the axle won'ttravel all the way up to your belly and cause extra damage. Mike; how much travel did you allow with the stop cable? you are doing is it working out well? Actually what's happening here is that bolt or shaft is welded tothe bottom of the axle. The shaft is then run thru a collar or 'tube inside of a tube' that's welded to theinside lower steel gear fitting. A little grease there helps it not to squeak. I was wondering how loose the fit would have to be, so that theaxle could tilt and allow one side to move more relative to the other? So far the setup works very well and I'd do it again. Many solutions though to this dilemma. The WWI guys were ingeniousat solving this very problem. For more clarity I can mail you (and anyone else interested) a .jpgformat picture that shows exactly how this thing works Mike C. Yes! Please and thanks

Mike, I don't know what a .jpg format picture is and whether you're referring to snail or E-mail but would sure like to see anything you have that shows meyours works. I have an anti-torque devise on mine that was designed by a friend but feel there might be room for improvement. Easier to make changes now, if needed, than later.!! Thanks, Don________________________________________________________________________________
