Hello from Yorkshire (another one !)

Hi,

I am from Leeds area of West Yorkshire and I am mostly carrying out work on Classic motorcycles (Jap crap to the British bike fans),

I have no formal training on machining but went to a decent school (blagged my way in !) that had Lathes, milling machines, welding equipment etc so learned basics at school and then during my early working life was making and reconditioning parts with the above plus other machines like surface grinders,

I now need to start being a bit more proficient with my lathe and milling machine, my first job is to bore out some carburettors from 26 to 28mm and need some advice on boring bar size etc,

Can someone tell me which section to post in for the required advice,

Thanks Jeff

Welcome! Lots of expertise and help available on here.

There used to be a thread relating to motorcycles on the Forum.

Welcome Jeff, there seems to be quite a number of bike rebuilders on here so hopefully one will be along soon with advice.

My advice would be to go for the biggest bar that will fit your lathe and the size of hole you wish to bore.

Is the material that the carbs are made from aluminium or Mazak?

What sort f lathe do you have?

Welcome Jeff from a fellow newbie and Yorkshire man.

I'm just along the road from you in WF15

As for boring bars, I'd ideally go for as large as you can without being crazy, to reduce the chance of chatter.

Hi

Thanks for the replies,

I understand the need to get a bar as big as possible to eliminate flex and chatter, I wondered what size I can go to before it gets too big to fit inside the bore of the carb which is 26mm so only needs 1mm off and depth to bore through is 90mm maximum, I'll put the question on the beginners questions,

Brian, thanks for your reply,

I think the carbs are alloy but will check, my Lathe is an Axminster C6 which I think is manufactured by Sieg ?

Thanks again

another yorkshire man, cracking,

I'm just down the road in wakie, i will be no help as i dont have any experience on mill or lathe yet.... but its great to see so many locals on here.

Re the locals, I am in Tingley so not far from Wakie either, one of those funny areas where my postcode is a WF one but I pay coucil tax and get my bins emptied by Leeds council,

You guys from West Yorkshire might like to consider joining a local club, I can highly recommend the Bradford club.

https://www.bradfordmes.uk/

We have members from all walks of life with many varied interests, not just railway loco's like a lot of clubs seem to concentrate on. Obviously things are on hold at the moment, but hopefully in a few months we can resume.

We have regular monthly meetings during the summer at various outdoor venues, and guest speakers during the winter months, along with a couple of auction nights where you can top up on junk tools and materials.

+1 for joining a club.

You meet fellow enthusiasts, learn from them, get shown things and techniques, and sometimes can borrow a Tap or Die for a one off job.
