Plz Bridgeport Y-axis Plans

[kenztasos]

Hi to all you Guys !!!

I am newbie in forum and the extreme world of CNC machining!!

I buy few months ago Bridgeport JB milling machine and I would like to convert to CNC .

I have install mach 3 with your help (looks awesome).

My problem is i can't find measurements and size for the Y-axis bearing bracket to design my own bracket for bearing and motor .

i need the dimension from the original y axis bearing bracket !!

I would like to build the X and Y axis on my bridgeport manual with hands and DRO before disassembly the machine to install ball screws and motors etc..

and something else

I buy Chinese motors NEMA 34 1700oz enough torque to connected straight to the ball screws..

What is your advice connected 1:1 OR buy timing belts and pulleys and connected 2:1

Thank you in advance .

ps : sorry for my English ... thanks anyway
