Hey I enjoy seeing people put their theorise to the test. I have a budget but I also like do the best I can. As I already have the screws then thats fine. The upgrade to a water cooled spindle was good advice and still stays , just, in budget. If I cannot afford it then as you say I will save. Biggest problem is deciding in what order to buy stuff.

I will do a sketchup of my gantry redesign and get some coments. probably at the weekend.

Thanks again
Bruce
