fork slider woes
« on: 23.10. 2009 22:46 »
Hi Chaps,

Just as I thought I was making a slight bit of progress with this bl**dy project another problem.
Had me tea then, off to the sancturay called the garage to rebuild the A10's forks.On with the radio,out with a beer ,lay all the new parts ,stanchions ,bushes,seals, shims etc on to a nice clean bit of cardboard, take the freshley painted sliders down from their hooks.Get the picture so far so good.Reassemble the first fork in 15 mins flat ,this is easy the second one will be even quicker ..........................3 hours later I leave the garage 2nd fork still unassembled and headoff to the sanctuary of indoors!
To cut along story short after much micrometering assembley and dissassembley the lower fork bush wont go all the way down into the slider and despite desperate attempts with rotary wire brushes on a long shaft ,metal polish, a worn out flap wheel on a long shaft  dimple I still couldnt get it to go to the lowest position.I concluded that there must be a bit of corrosion or a little dimple internally caused by an external knock to the slider down in the lower part of the slider which is doubly diff to get to because of the damper thingy rod sticking up a couple of inches.
So is it another bit for the scrap bin and another few months looking for a replacement,or any ideas?
Cheers Spyke.

Hi Spyke,
I had a similar problem due to a dent in the leg,
I used an old forkleg and bushes without the bottom nut, I cut a notch in the bottom of the bush and leg
and brazed in a piece of tool steel,a little proud of the end of the bush
then I ground this to the inner diamater of the fork leg
then a cutting edge on the tool steel !
reasoning it would only cut where the dent was  *idea* *idea*
I put the fork leg in the lathe chuck and held the outer leg with a shaft through the wheel spindle hole and held on the toolpost,
slowly turning the fork leg it machined away the dented portion
It took quite a whiile to remove the damaged patch!!!!!
