|
|
Ok lets see which of you knowledgable chap (and chapesess) can answer me this!!
I have bought a set of risers for my build and they are obviously of a Harley and an Imeprial M12 not a Metric M12 as there is very little in it but they won't go through my top you. I can't drill the yoke out cause its got rubber vibration mounts sleeved with metal which is too thin to cut back.
So question is is it possible to get an imperial thread on one end, unthreaded in the middle and threaded the other end metric M12 ie
Sorry its a crude drawing only have paint on the work pc!! _________________ Anything you say may be taken down and used as evidence in a court of law, or boxhill forum!!
The only reason I'm fat is because everytime I f&*ked your mum she gave me a biscuit!

I'm sure I could make you such a thing...
"imperial M12" is probably a 1/2" UNF or UNC thread... they are both (Metric & UNF/UNC) 60 degrees cut _________________

Count the "threads per inch" on the imperial end 13 = UNC, 20 = UNF _________________

Seriously!! that would be amazing, and definetly worth a couple of beers and a guitar lesson I reckon I've got all the original bolts etc so can work out the lengths and what not then show you the threads etc.
Will give you a bell, bit tied up this weekend as gotta go sort me mortgage out maybe weekend after? _________________ Anything you say may be taken down and used as evidence in a court of law, or boxhill forum!!

Yeah np... any excuse to use my lathe next w/e probably better for me too as out on the beer this w/e.
BTW....
M12 usually is 1.75 mm pitch. i.e. the distance between 2 peaks, however, a lot of the Jap bikes use finer variants, such as 1.5mm or 1.25mm pitch.
1/2" UNF is 20tpi i.e. roughly the "peak to peak" (pitch) is 1.27mm, which is very close to the finest M12 (1.25pitch)
1/2" UNC is 13tpi - about 1.95mm pitch - therefore slightly coarser than the standard coarse M12 (1.75)

Because I earn over 10x what I did as a mechanic 15 years ago (working for someone else), & my father said he'd kill me if I went into the motor trade, he's still very much alive and capable of carrying out that threat... My enjoyment of tinkering would I expect be considerably less if I had to do it. _________________

I thought UNF/UNc were 55 degrees cut and metric is 60 degrees. |
