Re: Bédélia - stub axles on a larger axle
By: Tinworm Date: August 17, 2022, 6:08 am
---------------------------------------------------------
On Jim Tanner's recommendation, because my axle is going to have
some unusual forces on it (with its sliding pillar and steering
all on one point), I have up-rated my axle to a 40mm CDS tube,
but that creates its own problems for how I am going to fix my
Gemini stub axles in it. I may solve it all just by fitting a
shaft collar (plug welded to the stub axle's spigot), then
butt-weld straight to the side of the tube, as the collar with
the 25mm inside diameter has an outside diameter of 40mm.
In the meantime, however, Gemini has been waiting an inordinate
amount of time for their machinist supplier to deliver their
stub axles, so I will have to concentrate on other things,
myself.[img][/img]

Re: Bédélia - sliding pillar support structure at the nose
By: Tinworm Date: August 17, 2022, 6:16 am

Last few days I have been crushing and drilling tube to make the
support structure for my sliding pillar steering centre. It is
now pretty solid.
It all looks very agricultural, but then, so did the inspiration
car at the nose. Looking forward to this thing looking like
something nice to look at.[img][/img]

Note to self. You can get a split collar with a 17mm ID and an
OD of 36. Weld this on the right hand side of the spigot,
inserted inside the axle, with the 25/40 collar welded to the
outside of the tube!
If Gemini are unable to get a supply, get someone to turn a
thread on to some 17mm stock (if it exists?) and weld a couple
of 17/36 collars on and insert both (spaced out) inside the
tube and cross bolt, as on original car.

Looking like a plan coming together there Pete. :-)
It wont be long until you have wheels on it. I found things
easier in the cluttered garage I have when it rolled around.

Pete, would these be of any use. They are currently 20mmx71mm
stub and 22 o/do shoulder.
I can turn them down to 17.

Oh mate, that could be superb! Thanks for the suggestion. The
distance from the start of the shoulder to the end looks short.
It might take some working out. (like, how much shoulder I need?
etc)
The question is, if I welded a 17/36 collar on to the end and
then welded that into the end of the tube, would it be strong
enough? I'd have to do some really good welding (not my usual
pigeon-sh*t).
How does this look (see scribble)?[img][/img]

I can't wait for it to start looking like a car instead of a
bridge.

Hi Pete, I can turn a collar that is a press fit on the stub and
weld it both sides. It will just need to be welded
to your tube. I can also test it on my pit bike wheels to make
sure it's all good.

That would be absolutely amazing, Jim. Thanks very much!

Re: Bédélia - nose sliding pillar suspension structure done

sliding pillar tubes finished[img][/img]
Next I am making my axle mount box, to which the axle gets
bolted (with the sliding collars as the main bearings)
