new front fork slider
« on: 29.02. 2016 10:30 »
does anyone know where i can get a new LH front fork slider for an 8 inch full width cast hub, mine is worn out and even though i have fitted new bushes and stanchions i have far to much play in it. or failing that does any one know who can machine it true and make new bushes for it, the RH is OK

Cant seem to get into their website presently but I have a vague recollection Draganfly had some made, might pay to drop them a line.

I had some new ones made from hydraulic pipe, partially as I wanted to adapt them to run a fork brace to stop them twisting (on the race sidecar).

Appalling that they only last 50 or 60 years, what were BSA thinking  *whistle*

2nd hand ones are about, but most are getting fairly stuffed by now. Later A65 ones allow for a damper unit

tried them, no stock and it does not look as if they will have any more.

One option would be to cut off the bottom of the slider (there is a hydraulic bump stop in the bottom) so you just have a plain tube which you may be able to get bored true?

from my post on "the road rocket racing sidecar project" I posted this pic showing the sliders my engineer knocked up. I also wanted a leading axle and fork brace which influenced the decision. Sorry the pictures emphasis is not the sliders

As I mentioned mine were made from hydraulic tube and we migrated the rusty old slider fittings across so it looked BSA

Daft idea maybe, but how about sleeving? To start with, this of course would involve cutting the bottom off and welding it on again afterwards. Anyone any idea about the wall thickness of the sliders?

They aren't very thick to start with

Mmmm... as I said, daft idea. If one chooses to go trough all that trouble it may be wiser to true them up and make oversize bushes

trouble with second hand ones you have no idea how good they are when on ebay as you can't see them, going to the VMCC jumble at Shepton Mallet on Sat and have a look there, lots of bits and normally a good bike jumble.

Ok this is not rocket science.
You need to find an engineering shop that does line boring.
You then ask them to bore the hole in the slider true for the full depth
If the shop hads the gear to bore your legs then see if the same shop can turn you up some oversized bushes.
This is SOP for old fork legs.
If there is some one in the BSAOA on the list I am sure they have lists of shops that regularly do this work.
I got my B40 bored out by the local gunsmith ( how appropriate ) who also turned up the new bushes out of LG2.
So finally after several years of fetteling I had this bike all sorted & turned my attentions to the A 65 then some ******** stole it. *sad2*

well i found some good second hand ones at the VMCC Jumble, but they were chrome plated, so i had them blasted and took them back to bare metal now away for painting, tried assembling them first just to make sure.
