Re: For Sale - SQ4 MK11 1958

Or fit a sidecar, then you don't have to worry too much about the weight
and Squares make excellent sidecar tugs.

Re: Frame ? anyone ?

I've just looked at a rigid frame. Now it's obvious how it's been done. Only one frame involved. Keep up Will. It'd have to be something different in the way of an engine. Perhaps an early unit BSA from a plunger A10? Somewhere in the collection of images is an Ariel with an A65 engine. It's harness...

Re: Frame ? anyone ?

I'd be disappointed if someone chopped up perfectly good frames to create that but if it's making one usable frame from two scrappers well done. Once it's a runner it'll have the 'experts' scratching their heads. There's a T110 engine in a Norton frame not far from me. I'm waiting for the Model 50 e...

Re: Frame ? anyone ?

So the saddle tube is from the rigid frame?

I wonder why the saddle and tank mountings were cut off?

Your swinging arm frame is interesting too. HS? It's the tyre pump
mountings which caught my eye.

Re: Frame ? anyone ?

Is this what's left after the front of the rigid and the back of the swinging arm have been made
into a replica swinging arm Square 4 frame?

Another thought - where does the gearbox go - in front or behind the saddle tube?

Re: American Ariel import

I'm interested to see what the Despatch Book has to say. I've never seen a 5-digit number
on a 4-stroke, never mind one starting with 3.

Caveat Emptor.

Re: American Ariel import

Apart from any identity issues there are a number of features that would put me off. The rear mudguard looks to have been shortened and I can't see a head steady. Someone felt the need to put an anti-draindown valve in the oil system too. Enough to set me wondering what else there might be waiting t...

Re: Fieldmaster and huntmaster primary case

There are at least two sorts of KH primary chaincase. The first fits rigid and plunger
frames and the second fits the swinging arm frame. The first sort is longer than the
second and has a hole through the middle for the footrest which the swinging arm
one doesn't have.

Re: Is this a Lucas lamp?

Apart from the red lens it looks remarkably like an early 50s Miller lamp as
used on Vincents amongst others.

Re: Clutch springs

There are two advantages to a cork clutch. One is that the action at the handlebar is appreciably lighter due to the lighter springs. The other is that the clutch takes up appreciably smoother than a bonded clutch. Couple these advantages with a lined clutch cable correctly routed down the front dow...
