Hi Grumpy, you are correct, I do have a lathe, milling and welding equipment as I have a small 'sideline' business making and selling parts for lawnmower racing which is how I came across the HD8. I originally bought it with the intention of stripping it for racing but when I got it I saw that it was in such good condition I just couldn't treat it that way!
Regarding getting parts to me, I fairly regularly import alloy wheels from Australia, Ross Edwards, so I guess that if I found the parts that I needed in Aus I could get them sent to Ross and he would included them in my next import batch.
