It took a while for HPC to reply to me with some figures but the gent was quite helpful. I've now got a bigger problem they’ve quoted me £443 for the above belts and pulleys. That's a figure I just can't afford at the moment I've spoken to BSL and hopefully they are getting back to me tomorrow with a quote but it would have to at least half that figure to be do able. I've got my smoothstepper now and the customs added £16 Vat on top at the border then parcel force added another £8 for their handling costs?? Still it was a bit cheaper than buying the smoothstepper in the UK. I’m a bit gutted at the moment as the £400 + was a complete shocker. It’s my fault of course for not budgeting for it but it puts my project on a firm hold for a bit
. I’ll look into worm drives or something to see if they work out any cheaper as you can get anti backlash worms and I’m feeling once I’ve got the Mill up and running I can then make some pulleys myself (wishful thinking maybe) . Downside is I won’t be able to use the mill as a conventional one unless I rig up a worm engage/disengage mechanism. Hmmm maybe a car timing pulley could be used I have a couple of them somewhere in the garage.
