dobbers trike

[morrag]

Never bother with such troublesome clamps myself, preferring a prefabed box welded to the axle tube with a vertical flat mounting plate to receive the trailing arms. Morrag

Like this................. no chance of it revolving, and the load spread over a larger area of axle tube, simples..

had to force my self to drag the trike out today as a space in the depot opened up. went to my mates engineering shop and got him to cut and hole punch two steel plates to beef up my axle mounts which were too flimsy. he also turned down the end of a piece of tube which i intend to cut down the middle and use as a spacer, load displacer under the reliant ubolts to stop the axle tubes crushing. he has all the gear, instead of drilling he just punched the holes with a 40 tonne punch. cut the plate on a machine that made it look easy like cutting a loaf
took off the wheel and mudguard to get access. loosened the ubolts on the near side and took them off the off side, while the trike is sat on axle stands i jacked up the axle and slid in the new plate. luckily  i had another mount nearer the center of the axle which makes it easy to know the axle is sat in the exact same place.

.the new plate is to sit on the old plate and weld on. made it wider so the bolts dont foul in the old holes.

when i slice this pipe in half, [[one half on the top of each tube under the ubolts]] how do i measure to mark it so it is exactly two halfs

[dobber]

note the ubolt nearer the diff. wasnt really needed but came in handy to keep the axle in the same position

when slitting a tube lenthwise 

i lay a lenth of angle iron down it then chalk or marker pen a line down it ,, then measure equelly each way around to find the centre on the other side then mark that.

try it and youlle find it easier then i explain it ,,

As spanners says, a vee block or piece of angle iron is perfect.
Using proper axle u bolts and is way better than the ones that were fitted Are you welding on axle saddles to resist rotation.

got the tube cut down the middle but didnt notice that the bits we turned down to fit the ubolts were not done far enough in so had to be redone. gonna get it all put together. i intend to tack the half tube to the axle and to the ubolt to stop spinning. is there a easy way to make a saddle?
no photos as i have got grit in the camera lens by the sounds of it. second one in a short time.

[Olds]

You can buy saddles to fit escort axles. Not sure what dia. they are. For a light weight, low power application I would think that a couple of bits of angle welded each side would suffice. The main object being provide a flat, stable base to stop the tubes rotating under power or braking.

Hi Olds
Would you know where to get them from ?

this the sort of thing

[Olds]

Yep 

[dobber]

had a few minutes free so put my new set up on one side

[dobber]

remembered i have to sort a clutch pedal bush or bearing out. at the mo it just has a compressed rubber bung in the middle. any ideas or can some one lathe up a bush for a undisclosed fee?
