Hi there Anthony, The book is very useful - though is quite big (something like 350 pages) so scanning it is likely out of the question. Copies do come up on...

Hi Francis, the 2½" does indeed have a set of standards and I've uploaded a copy to the files section. These do appear to differ in certain areas from the...

Dear Friends If you take the time to download the 9F wheel set file from the file area, you will see that it is a special 3D drawing format that uses a royalty...

I recall somewhere seeing a 'limits and fit' table for O rings? Assuming a 1/16" O ring, if I wanted an, ID of 0.25" what depth and diameter spotface cutting...
Hi David, have a look at: http://www.barnwell.co.uk/pdf/O%20Rings.pdf That has all the info for sizing grooves etc for O rings. I don't know what you will be...

Also remember the "rubber" or elastic material of an O ring is not compressable like convential packing. So the cut out for the ring must be wide enough to...

Hi David, You're only looking at a simple low pressure static seal so as long as the O ring is compressed when the 2 halves are bolted together you shouldn't...
What is it, an oil return? Not sure on material, you can get cheap natural rubber rings, or silicone, or viton. The cheap rubber ones are better with oils than...
hallo David nice bike haven't been on one of those since i was a nipper if your crank-case is good i.e. not warped not really necessary , no science in...

Many thanks John LBSC gives the Pansyette cylinder block a width of 1-15/16", which coupled with a couple of frames at 3/32" provides a reassuring 2-1/8". (If...
