CAREFUL!
Make sure you purchase wheels with SDG in the description as
they have a much greater variety of bearing availability. To get
good bearing choices, 35 mm bore is what you want. The link
Stefan has posted has that, but always check before buying, or
ask for a bearing number and check against dimensions. 37 mm
bearing OD doesn't have a lot of choices.
Chris, please post your spreadsheet.
Bearing boys are a great source, and very helpful.

I spoke to 'fun-bikes' earlier in the week, they said 17" wheels
should be back in stock in about 2 weeks.

Hey Rhys. I see we have a forum for bits and pieces, you could
kick it off?

Amongst everything else, I have been looking for some suitable
wheels for my project, the 1908 French GP winning Mercedes.
Interesting when I scale the car down to have a 66" wheelbase,
the wheels come out at 17" in diameter! I was thinking about the
1906 GP Renault and got very into that because in practice, it
ran on wire wheels, changing to Mitchellin rims for the race.
The Mercedes however only ran on Mitchellin wheels with
detachable rims on the back and non-detachable on the front.
I decided I would make the Mitchellin wheels myself and use a
steel 17" rim.
I have just come back from 'Central Wheels' in Coleshill, with a
set of four brand new rims, without the spoke blisters and
undrilled. Perfect for what I need, £236. I recommend them, they
can do anything, great shop.
I want the wooden spokes to be 30mm wide but that's way beyond
my laser cutters ability so I am going to cut some 15mm thick
Hickory (I bought for the purpose) on my laser-cutter and try
that. If its OK then Ill cut two, glue the two together and see
how we go then quick dabble with a spokeshave and see how it
looks. If it works OK then work can commence on the remaining
47!
The wooden rims will be made in a similar manner on the laser
but will need four laminates of 12.5mm thick in American Yellow
Pine.
I will use the rims as the outer section of the building jug
with a 1" dia rod supporting the spokes in the centres.
I'll then drill the rims to suit, get them powder-coated, then
screw and glue them to the Mitchellin wheels.
I'll start with the back wheels because they look great and I
can't wait to get started to prove the design really.
The chassis is all aluminium as is the bodywork and whilst I
have drawn it all up, my pal at Shapecraft in Hinckley is going
to make the chassis and when I have done all the loops for the
bodywork he will English wheel the body panels, wire edge all
raw edges and weld it all up. Seems years away but it won't be
I promise.

I've attached the bearing tabulation as requested by Rhys,some
additions to the original one with info on the Honda ANF125
wheels which are readily available, new or second hand. What
struck me is it should be possible to use the 32mm o/d bearings
in wheels that use 35mm ones, with a sleeve of 35mm o/d 1.5mm
wall tube, might need some bearing lock. That means there are
25mm bore bearings that could be used in rear wheels.

Bearings in rear wheels Chris? Why?
Can you post that to the "Getting Started" section so it stays
visible.

For the free running one, with the pit bike wheels it's then
only a matter of removing or fitting 4 bolts to change over from
fixed to free. It's also a cheap and easy way to locate the
wheel on the axle radially anyway.

TBH Chris, I would recommend forgetting the idea of a free
wheel, especially if there is to be almost zero friction. The
car will drive hard one way with drive, need considerable
steering input to stay straight, and equally vicious the
opposite way on braking. The only time the CK runs straight is
on a neutral throttle input, ie no acceleration, no lift off.
It's not a great idea, except if you have the need to turn tight
circles slowly. Most have abandoned that idea some years ago.

I have to agree with Rhys, from the limited use I have had with
the MG to date, I will definitely be changing the rear drive to
both wheels.
When accelerating and braking hard, the single driven wheel
causes a lot of pull on the steering and hard cornering between
left and right is unpredictable, (could be my driving of
course!).
