Looking like more progress Pete. From your previous work I bet it will be far from agricultural.
Is there any pitch to the suspension pillar or is the trail in the pivot at the bottom?

Thanks Jim!
As regards caster or trail, the pillar will be vertical - no lean. However, the steering has 2" of trail designed in (with centre of rotation behind the axle), and I am making the axle attachment adjustable so that if necessary I can slightly lengthen the wheelbase by packing the fixing, most likely no more than an inch

Re: Bédélia - steering and nose

I am been consistently busy, but haven't been updating my build journal.

I now have two spreadsheets: one is a record of spending, the other a running total of the weight of the build.

I have made my quick-release steering column with main drive sprocket, which will drive a chain pulling my steering cable.

Also, I have made the nose section supports, which need to be able to look solid, but also need to accommodate my feet in boots and allow my toes through the front. (you will see why in time). So I made these out of angle iron. They are bracketed and welded to the removable nose suspension unit. This allows for the possibility of changing the front it I later change over to Ackerman steering.

Chuffed with my car horn. Got it for Ł16 incl p+p on ebay.

Very nice, loud parp!

Re: Bédélia - sliding pillar suspension

I have been working on my nose suspension

 I made a sliding collar which will bear down on the main spring, once I know how much it should be compressed; it will then be fixed in place. The collar and spring will be housed in a tube which the collar has been made to fit. But I won't cut the tube until I know how much compression I need.

Next I need to make the steering block.

I have been holidaying in Portugal, where Lucy (my other half) has been performing in a music festival, while I have been exploring Roman aqueducts etc, so there has been a bit of a interruption in the build.

Since getting back I gave been experimenting with wood bending, which has been quite successful. More details pending.

Re: Bédélia - stub axles on a larger axle
« Reply #50 on: 17 Aug 22, 12:08 pm »
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.

Re: Bédélia - sliding pillar support structure at the nose
« Reply #51 on: 17 Aug 22, 12:16 pm »
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.

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)?

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
« Reply #59 on: 20 Aug 22, 12:24 am »
sliding pillar tubes finished

Next I am making my axle mount box, to which the axle gets bolted (with the sliding collars as the main bearings)
