maybe old knowledge, but in the process of fitting ski axles,decided to make external box to fit blade to ,and weld tubes to this box to insert into the square ends of axle (couldn't find appropriate size box section) had no tube of appropriate size,so cut a tube length wise into 2 c sections welded them back together which formed an oval tube which fitted exactly into the diagonal of the square box , when the bolt(fitted to the v of the box)was tightened it forced the welded side of the tube into the opposite v of the square ,locking the tube in the correct position ,careful positioning of the ski box to the oval tube meant alignment perfect each time refitting ski .

I'm planning to use skis for my next build, so this would probably help. But I'm afraid I'm struggling to visualise what you did. Any chance you could post a photo or diagram to complement the text?

Sounds complicated. Have a look at the pictures in my album for easy methods of using skis.

I was just about to say exactly the same,Only reason I did it my way was because I wanted to retain the ability of reusing my original tubed stub axles in case of a breakage on the skis,and I didn't want to cut my skis down to fit into my 50x50x2m stainless axle.But having used them and hit several deep gullies and potholes without damage then probably would have been ok cut down to size .If I was building from scratch would just simply fit straight to frame into a u section, of the appropriate sized axle'. However having gone down the line of splitting the tube ,to fit into a box(because no suitable size ),I would do that again since,after the metal loss of two cuts,on rewelding forms an oval which fits into the boxes diagonalcorners,and as long as the fixing bold is placed on corner of the box ,on tightening up locks the oval into the opposite corner,impossible for it to move,and negates having to over tighten the bolt.
Don't see me ever building another where I used tubed axles,after using skis would always go down that route, undoubtedly by far the better system.No more shaken eye balls as well as others lower down when hitting rippled beaches, Good luck with it

Thanks folks - sounds like it's a lot easier if you're starting from scratch. I've studied Bynorthsea's photos, and come to the conclusion that I need a lot more practice to achieve workmanship like that!
Bynorthsea: do you ever get up to Redcar? Miles of largely empty beach, and next to no obstacles like pill boxes or tank traps. I get the feeling that the sand is smoother too, though I was maybe unlucky when I went to Fraisthorpe.
