For better or worst

I Have produced 350 pair's of Lansdowne dampers the general feed back over three years as been excellent..BUT i do get a odd email complaining about harsh action.
It's surprising what can be the answer..I sent a pair to the UK last month for a Seeley , the guy rang to say the forks where harsh,which normaly means they bind and stick.
I suggested he sent the forks to me for inspection...yes they felt harsh.
On full compression the fork was loathed to return, with a horrible grinding sound.
When i un-screwed the top nut it sprang to one side in the stanchion! Infact the damper had to be forced back into the centre before it could be screwed back in!
Turned out the slider had been machined OUT OF TRUE,Forcing the damper over to one side. the spring was jammed against the stanchion bore with high resistance..enough to prevent the fork from returning!
Re-maching the slider restored the smooth action needed.

Another complaint ; Rough action, this was due to the Commando slider being completely WORN OUT! New sleeves[steel inserts] and nylon bush's solved the issue.

Lastly, you would not expect a brand new £35000 manx to be poorly assembled? I had a "complaint" regarding poor fork action after fitting my dampers...

The problem was the wheel was to wide to fit between the forks! The forks had been forced apart causing the sliders to bind...thats a brand new £35k racing bike from the best builder in the UK!

SO WHAT CHANCE IS THERE FOR 40 YEAR OLD WORN,CRASHED COMMANDO FORK ASSEMBLY :!: :!:

Hi John,

Is the best builder based somewhere just north of Preston?

I hope to be placing an order in the near future for a Proddy Racer I'm building. I just hope A-N have done a good job on their 'Norvil' sliders.

I've now got to grips with the 850 I put your first set in (just caned it senseless coming back from the Garstang autojumble ), and they work very well everywhere, but It's most noticeable under braking - it's totally planted and still manages the bumps brilliantly.
I noticed your posts regarding springs binding, and I fitted RGM progressive ones in mine and have a very well behaved front end. I have considered using external springs on the Proddy racer, but as my current setup is very far from broken (nigh-on perfect) I see no point in daring to be different.
I should be able to comment on track performance later this year.

I got a bit of advice from a Kiwi boatbuilder once (in reference to a resto project): "You can never afford to buy the kind of work you are willing to do for yourself."

I think about that often when I am working on my projects and puzzling over how to solve various problems.
