No I haven't, Paul. I've made sure the spindle is up good tight.
As the swinging arms moves left and right the nuts and spindle doesn't move at all. So all I can think is the rubber is gone soft.
I want to get it sorted this week for the Castle rally. I'll report back.

Good news, 50 miles this evening and no seize. Not sure if it helped but I've put some two stroke oil in the tank.

I'm getting confident things might be OK. I did 3 Jobs yesterday in Lee on Solent, Southampton and Frimley. I kept off the motorways doing around 120 miles. No siezure. Great stuff.
I was going to get at my swinging arm today before leaving tomorrow for the Castle Rally, but I've hit a snag, Alan who got the metalastic bushes out for me last time was saying he couldn't understand why I was having all this trouble. I've got new ones in my Huntmaster and they are fine. Well they aren't,!l

Here's a video
https://youtu.be/tTop18jL01g

I've ordered some bronze bushes which are 32mm OD and 22mm ID by 50mm long. Now to get a tube with a 14.25mm ID and a 22mm OD this is actually the same dimensions as the center spacer in the swinging arms but instead of being 4.5 inches long I need it to be the exact with of the swinging arms plus a bit.
I got the bushes from here https://simplybearings.co.uk/shop/Beari ... index.html

So that video is showing lateral movement on new bushes?

As someone contemplating fitting swinging arm in the next few months, I shall be watching closely!

Very puzzling.
My '56 swing-arm is still on its original bushes and seems fine - certainly good enough for me to wear out my rear Roadrunner in 4k miles....

My 3 other swinging arm bikes have only just a small amount of lateral movement, I've not changed those bushes, I'm guessing they are all original. It is entirely possible though that we've done something wrong when fitting them.
It will be a week or two before I'll be able to do the job as I've still to source the tube.
I should have said that David Anderson has previously posted on this mod. I'm doing it the same way. Thanks David

Looks like a damp ride to Wales this morning :D
I'm getting the bottom end of a spare engine done by SRM in Aberystwyth so as it's the Castle Rally close by I'm going to get the engine over to them on the way.
It's going to be a long slow ride as I'm still nervous after it's niipping up. At least I've got some water cooling today :D

I once converted a Featherbed swingarm to Manx spec .
It involved shortening the main tube of the swingarm, only possible by mounting the whole thing upright on a milling machine.
Lot of work to set up right.
Advantage was that the bushes have a shoulder so they cannot move inwards.(thats why you have to shorten the tube)
They where held against turning by a grease nipple.
It used the standard spindle.
I think I bought the bushes from Unity Equipe (I dont go there anymore.....nasty people )
Paul Hamon from Alton fame also did make conversions.

Cheers Vincent,
I've made it over the Severn without being blown off the bridge, water cooling is working. The extra weight of my spare engine is keeping things steady
