Post by: downlowmatt on November 30, 2005, 02:36 PM

Ok, here's what I started with... a mullered floval in need of some good old fashioned loving...

Looking a bit better after a good old fashioned rub down with fine wire wool and autosol... (don't worry I know they are the wrong forks I've got the non stamped ones)

Don't worry chaps, thanks for the offers of help, but I contacted Graeme around a year ago who put me on to his talented mate Mick...

Mick lives way up in the North East but wey-hey man he knows how to work metal... this is what he did...

First an oversize piece of ally was machined from a block...

.. it was then roughly fitted to the frame....

.. tig wleded in and then ground down to size ...

.. and the slit cut in...

... pretty amazing in my opinion.....

yeah looks good but i didnt trust just having the top bit replaced
as it is still the weak point .hence why i got donker to
make me a whole new tube .so at least ive harf a chance of not breaking it
lol
