Some good advice there chaps thanks.
Well I still haven't heard from BSL but my box of bits turned up this morning from AFC. Before ordering I asked them for a price on machining the bores etc and confirmed the sizes I wanted, but alas they couldn't do it and a gent down the road that could was going to double my costs so DIY it was. Only thing is even though I had confirmed the bore sizes with them ie 9.5 mm on all the small pulleys I got a 10 tooth pulley through the post where the boss and bottom of the teeth only turned out to be about 9.8 mm so I cant use it grrrrrr. HPC had told me I needed T10 on this axis but then I was told no you don't, T5 will do, just make the belt wider. OK I thought that sounds logical for increasing the power capabilities but won't having a smaller pitch mean that the diameter for 10 teeth would be too small for a 9.5mm bore? Nope I was told the max bore is 13 mm on these. Unfortunately the person giving me the details read the wrong bit in the book or something. Anyway no complaints about their customer service as they were quite apologetic and promise to sort it out first thing on Monday it looks like I can get a 10 tooth and 72 tooth pair with a 1/2 belt if I go for imperial (3/8 pitch) so that's what I'm doing. I did have another radical idea on the keying front and that was due to me not using the handles on the axis any more Id either fix the pulleys to the handle some how or turn down the handle and bore out the pulley to get a nice tight fit and a spot of weld to finish off.
