Do you mean the parts total price is in the ballpark of Priest's kit or finished product? I've dealt with McMaster and yes, they have quality stuff, but you can equal their quality for less money by shopping around. They are, after all, just a mega industrial hardware store. Shopping around takes time, but you learn a lot doing so.Once you price out the parts you are pretty much in the ballpark of the price,
Someone above mentioned that the TTS is a hard no for them. I respect that but for me consistent tool length registration is a must,
YMMV but the PDB + TTS is convenient, fast, and gives reproducible tool heights.
What is TTS?
How does a power draw bar give reproducible tool heights? Is the TTS a tool holder system like what is found on a CNC machine? In that case I understand how using high tolerance tool holders will give repeatable accuracy in tool heights. What kind of jig allows you to place the various milling cutters in a tool holder system in order to get the same tool height when installed on the mill?
