The
eagle Steib has landed! Now in my shed and looking great. It will be a while before I get around to it as I have the little BSA C11 to finish - it's nearly there - and still struggling a bit with the Electra although that is so much better than it was.
The Steib is mostly there and is in very sound condition. I plan to have the body (or boat as it's known) painted by a local sprayshop to match the B'Zuki tank, and will paint the chassis black with coach enamel. I can see me producing huge piles of swarf as I make the mountings......

I'm excited for you!

I'm slowly cracking on with this and am making split clamps for the bike frame out of alloy blocks. The front upper will go on the downtube just below the steering head; the lower on the tube going beneath the engine. Rear lower will go on a 10mm plate bridging the swinging arm spindle, rear brake pivot and pillion footrest bolt, rear uppers (2) on the seat tube and rear diagonal going up to the suspension unit. I'll have to chop the toolbox about a bit and modify the cover for clearance.
The body is booked in for paint at the beginning of March by which time I should have the chassis all hooked up. I hope.....
Machining and producing vast amounts of swarf in progress:

All looks exciting stuff Ian. Can’t beat playing around with lovely chunks of ally.
Best of luck & look forward o seeing the chair once painted 👍
Cheers, Michael

I was getting a very poor finish on the bore using carbide tipped tools. I've reverted to a HSS bit holder and it's so much better. I generally stick to HSS anyway but was pesuaded against my better judgment to use the carbide type. Waste of money in my opinion, although may be good for turning tool steel and the like.
It just shows what can be done with a small "hobby" type lathe as long as you take your time.

I've been occupying myself with B'Zuki sidecar attachments and think I have it all sussed. The attached shows them on the bike. The rear lower one isn't finished - it will be a 10mm mild steel plate picking up on the hollow swinging arm pivot and the conveniently positioned rear brake pivot just below it. It will also have a 3/8" bolt through the pillion footrest mounting to the rear of them.The others are all clamps made out of alumimium alloy.
Most of the vertical load is taken by the 2 lower ones, and probably 75% of that by the rear one. The top 3 act as triangulation points both to brace the whole thing and to allow and set the lean out. They will connect by means of seamless tubing with threaded inserts in the ends to allow for that adjustment.

Looking good Ian. Look forward to seeing the next progress report photos 👍

From a man who can't do anything without at least 7 attempts which all go wrong I would like to say jolly nice work sir. Its looking like its going to be a fun machine.

7 attempts? Sometimes I need far more than that. I call them prototypes.......

I'm now starting to get an idea of the setup. This is the chassis in position with 9" sidecar wheel lead, but a bit further away from the bike than it will end up to allow adjustments. As I thought the forward mounting on the chassis is far too far forward to be of any use so will need to make more split clamps. The body will be going off for paint at the beginning of March so no rush.
Mr Waitrose's grocery boxes are ideal for this job!

Looking good. Taking shape.
Curious onlooker: 'scuse me, what geometry you using on the sidecar?
You: Oh, the Waitrose geometry.
Curious onlooker: Ah. Right.
(Sculks off to consult Google AI) 😂

Reply to the curious onlooker: initial setup will be 9" sidecar wheel lead, 3/4" sidecar wheel toe-in, bike lean out 1/4" measured at the wheel rim. All except sidecar wheel lead seem very sensitive so my mountings will allow plenty of adjustment.

Some pics of my various struts / tie rods in position before welding the ends on:

Looking good Ian.
I was just watching an old episode of “The motorbike show” yesterday man. Henry was sampling a sidecar outfit for the first time man, he loved it man. He was waxing lyrical about the joys of riding one man and how we should all go and buy one man.
His was a Ural….. man
Looking forward to the next instalment of photos 👍
Cheers… Michael. Man😁

Oh no, if Mr Cole likes outfits then I'm in real trouble! Man......

Just a quick pic showing struts all welded up, painted with toolstation's finest satin black and cutouts made in the side panel to clear the mounting clamps:

Proper posh Ian, with the Suzuki that's going to be a nimble bit of kit.
May ask, who is going ballast? Or will just be a removable dod of lead ingot?
All the best, Bill
