This is experimental, not fully proven and for discussion only.
The steering on the BSA is Pitman arm, and while some might find this system absolutely fine, I find it twitchy at speed and hard work in tight corners. My arms have got used to power steering and if I lose a little road feel, I can cope with that.
I have been trying various solutions with in - line planetary gears and not having any faith in the results enough to take the idea forwards. Too much lash and, not enough connection options have made me kick that idea into the long grass.
So, try to build a rack.
I saw a video from an American (I think) fellow who has a good deal of skill with metal (1908 rick) Rick Eggers? I think who made a rack from scratch for his kart. I don't have access to high precision tools (eyes can't pop a centre to less than 0.3mm anymore either) so I improvised around his design to allow for poor tolerances with shims. Anyway, here is a short video of it so far.
Comments please.

Morning all.
This is a short video of me playing around with a design for a rear axle.
The reason I am posting it is because, like all things, it is probably not new and, therefore, if someone has had a go at this before, you can point out the pitfalls of the design. All comments welcome, positive or negative.  (I always miss something)

Morning all and seasons greetings!
Just scored some beautiful small cast iron axle stands from Marketplace and four chassis punches for a tenner all in. Whilst collecting these, the vendor was starting to clean up a Clarke CL430 metal lathe for sale. They didn't put a price on it but it looked well looked after. (they are downsizing and need to move soon)
Has anyone got any experience with this machine and its value (or otherwise) they would like to share?

Morning all, and here I go again experimenting.

This is a winter project for me on the engine.
The aim is to widen the power band of the engine by having self advancing timing as the revs build, Like most motor vehicles.
Peak power should not be effected as our engines are designed stock to only produce peak power at about 3500 revs.
Quite a few people add 4⁰ of advance by filing the key. I have not. Doing this shifts the peak power up the rev range.

with a 7:1 gearing plus TAV overdrive at 1:1, 6000 revs would give approximately 60mph!!! on a 17" wheel + tyre so our rev range for power is probably best low down, and ideally over as wide a band as possible. If I were a Kart with small wheels, filing the key would be a great advantage where I needed it as the gearing is lower. As we state 35mph as an aim for the CycleKarts, having a wide band of power around 3500 revs should be the aim.
I have come across a fellow  in Canada who is producing basic CDI kits for our engines and persuaded him to ship me one.
If it works it should put less stress on the engine, have a better fuel economy, a wider power band, wider torque band and be easy to start.

These things are quite new and the fellow is a small business trying to establish a market. It is an experiment and I may go back to stock if it doesn't work out. If I were you and you were thinking of giving it a go, I would let me spend the small amount of cash on it first and see how it works out.
Thoughts please

So, I have acquired this. I know exactly what you are thinking, and yes it was possibly just more junk but here it is. A frame from an aluminium scaffold staging rated to 250kg, 20" wide, 61" ish hook to hook, not twisted or dinged, fairly lightweight and possibly, just possibly adaptable to chassis material. Rails are about 3" by 2".
Semi elliptical springs on the front would give me the wheelbase or there-about.

It's time to employ group think. Let your thoughts run freely please, no such thing as a bad idea, they are just starting points for improvement.

Question.
What would you do with it and where would it lead you in terms of inspiration car?

Got this in my feed today...

Simple reverse if you have a battery

The post lady dropped off my rather natty Nomex brown boiler suit today, as you can see, it brings the bad boy out in me and with a shirt and a spivvy tie, you may know me as "Slippery Jim" when the effects of the Nomex kick in. 

Feel free to take the Michael.
