Help With a number of build issues & uncertaintities

[mekanik]

Please do not buy any components yet, get a design together ask for comments and the guys will make sure you don't order anything unsuitable, if you can possibly stretch to profile rail this will make a far superior build, there is a company called FSA that trade on ebay that sell second hand rails and Jazz for one has had good results using that kit.
Good luck on whatever you decide.

Yes don't buy anything yet, It's the worst thing you can do and classic mistake.
Another thing is don't rely on the sellers to advise because they will only try to sell you what they have in stock or need shut of. Often this or some of it isn't the best for your needs so just hang fire and check with us here before ordering.

Start with design and then work from there. Motors and drives sat on a bench are just wasting warrenty and you can bet your last dollar they will be out of date by time machines built and cutting.
