It is a lot nicer here today tooI am eagerly waiting for the postman
R U feeling better today, mate?Nice morning here I should be out but its nice sitting looking out to the nice colours on the trees
drinking my coffee. Ahhhhhh chillin for 1/2 n hour
That's a bummer.Sun shining here as well
Just burned me porridge
does you do it in the microondes?
We do, it don't burn but it can splash it around a bit if you forgets what you is doin!
Right, oft to get myself sorted out to take the Pluriel for its MOT.
Crossed fingas!

..that I am trying to modify some Sturmey Archer Drum-Braked bicycle hubs so that they can be driven by half-shafts (like a car).
Working out possible ways "how" to do it is giving me a headache.
Different internal spacers will need to be made on my lathe.

Sounds very interesting, what you up to ?

Tricycles (pushbike ones) normally only have one rear wheel driven because they have no differential, mine will have both rear wheels driven, the 2WD "diff" will allow for one wheel to go faster in turns without scrubbing the tyres.Sounds very interesting, what you up to ?
Most bikes nowadays have disc brakes but I find them fiddly to set up and keep working properly, and so I want to use drum-brake hubs.
Now these types of hub are normally un-driven and just freewheel on a 12mm axle. I am trying to change it so that a 12mm half-shaft drives the hub through the backplate.
Essentially I am trying to create for a Delta tricycle a rear-wheel drive system that drives both rear wheels through half-shafts and uses standard and proven drum-hub brakes.
I can't find anyone else that has done it, so there is no one to go "copy" its all investigate, try, do. Which exercises the grey matter.

I have a mobility scooter chain driven diff for my model truck (not adapted yet)
Maybe a freewheel cog could provide the needed slip in the drive on one side ? (had a think and that wont work)

Sturmey hubs alone makes my head ache.
Good luck with it!

I have an 8 speed. They are great as nothing should go in the mud or chain fall off when hopping off kerbs on the town bike.Sturmey hubs alone makes my head ache.
Good luck with it!
now the speed you can get out of an 11 speed is better than most road bikes
Bettern the three we was limited to when I was a nipper. Gives a much tidier back end too

Got a dental appointment 4 a checkup at last - 23rd December. First one since pre-first lockdown .
.
Been busy fitting a noo back door to me garage today. Existing frame is slightly out of true, so it has taken a bit of careful adjustment to the hinges (fiddling). Had to cut the top hinge into the frame a bit deeper, and make a spacer to build the bottom hinge out a bit. Then had to grind a bit of the concrete off the floor as it was out of level. And a few mm trimmed from the closing edge for the final fit. Needs a tiny bit more grinding off the concrete to get it to close properly but it has started raining again. Managed to prime the planed edge - all other surface were primed n undercoated last weekend as preparation. So should be weather proof until it stops raining.
OK, I made a new spacer for one of the hubs and put together a very simplistic "Proof Of Concept" model of what I am trying to achieve.
The POC model includes:
I guess I will need to do more to work out how to implement a drive-dog/drive pin affair.
The POC model includes:
- an outer axle-tube
- a 12mm bolt masquerading as an axle
- Some 12x28x8 bearings
- A modified external spacer to allow the hub's backplate to float free.
