Line reamer for fork bushes

Post  falcone on Fri Jan 02, 2015 10:07 pm

Does anyone know whether the club has a line reamer suitable for the tufnol fork bushes on a Falcon 58? I think that the size is 1.095". I am also looking for some bushes, although I assume I will have to get them made. Does anyone know what grade of tufnol is suitable?
Thanks
Marcus

Marcus have sent you a p.m. with regard to line reamer,
I always used "whale brand" tufnol when I made new bushes

Line reamer

Post  Mike Cambray on Thu Sep 28, 2017 7:53 pm

I am in the same position with my forks. I need to source/make Tufnol bushes and line ream them. What is the position with borrowing/hiring the line reamer?

Unfortunately the reamer was with a man from Hertfordshire who died suddenly, I contacted the family, but it could not be found, sadly we do not have it anymore

Marcus / Mike,

Please find below a copy of the reply I received last year from Tufnol when I enquired about the correct material for fork bushes.

Hope it helps!

Cheers,

PeterW

Peter
Apologies for the time taken in responding to your message.
With regards to a suitable material for your motorcycle, I would suggest the existing parts is based on a cotton fabric laminate.
Of this range of products, Tufnol Carp Brand may be the one to consider, which has higher mechanical properties in comparison to the other grades in this group, also the fine weave cotton fabric reinforcement lends itself better to thin walled components.

http://www.tufnol.com/materials-full/fabric_laminates/carp-brand.aspx

Im not sure where about youre based, but there are a number of resellers and machinists of Tufnol products around the country. I would personally look at buying tube(s) for this item rather than solid rod, and you may find that resellers are limited with their availability of tubes.
Wed have no problem with supplying tubes of a suitable size, and/or the actually finished part, however, a minimum order charge would be applied to the finished part, so quantity could play a factor.

Thanks Peter, what a great reply from Tufnol. Did you take them up on their offer? Or source tube elsewhere? I'm in Cumbria so a local reseller or machinist would be very helpful. Many thanks for your post.

Just out of interest what size is the required reamer?

Can you not use an adjustable reamer with a guide?

That is exactly what the original factory tool was, there are 2 sizes if bush 1.096" and 1.120, the tool is an expanding reamer with an 18" long guide tube screwed to one end which is about 20 thou down on sixe and a second sized tube behind of a similar length with a tommy bar hole in it

The outside diameter of my sliders are 0.85". I haven't plucked up courage to knock the end caps off the fork legs yet but from a rough measurement I'd guess the inside diameter of the fork legs is around the 1.096" you describe.

dimensions

Post  piston 197 on Sat Sep 30, 2017 4:52 pm

The dimensions I gave of 1.096 and 1.120 were for sliders on 1949/54 Falcon and Merlin , if your sliders are .86" I guess you have a Kestrel with the smaller forks ??

Kestrel 66 sliders should be ⅞ (0.875) inches outside diameter.
