Hi,
I quite recently bookmarked (thought I bookmarked) a UK source I found on the web for HE15 which thay had in sizes including 2 1/4". But now I want to buy some I can't find the bookmark :-( Can any perceptive person guess which supplier it was ? It was a fairly normal model engineering type of supplier but I've just waded through all my links and I can't find the one I had in mind and none of the others seem to sell HE15 in 2 1/4 inch diameters.
Thanks,
