Help with bridgeport X & Y powerfeeds not working

$

Hi

My names Marc and I live in the uk & I am new to this site but have been reading a few threads here and there for info and just general reading about other people’s projects

I just bought an Adcock Shipley bridgeport which is in need of some tlc but it was picked up from a friends friends yard where it had sat outside for 6 months for just £300 so I bought it without seeing it as I thought it was worth a punt and like reviving good old Machinary

Anyway I got it in a fairly sorry state as fully expected and have so far been very surprised how good it seems to be underneath

I have stripped the head and spindle and have already ordered rebuild kits from H&W machinary repairs in the states who I see are users on this site?

I have tested all electrics and everything works as it should except the power feeds

They are both original Bridgeport X & Y feeds,

The X feed motor was badly bent I’m guessing during transport long ago and it won’t spin properly as it jams due to a bent shaft but it does try to spin so I know it’s not a dead motor

The Y feed motor when bench tested on its own does run fine when connected on its own direct to 110v

But although my boards and contactors etc seem good I can not get anything working when wired up but the wiring could well be wrong as it’s been crimped here and there blatantly

It has the Quinton Crane board and the erskine changeover relay duel long/cross board

Just to start I am trying to soley get the Y feed working as I know this motor runs fine,

I have tested the 50k potentiometer which seems fine, the rapid traverse switch tests ok as does the forwards/reverse switches

What I’m not sure of is how it all wired up?

I can follow the diagram I have but it doesn’t show clear enough for me how to wire into the forward and reverse switches?

Is there a way to bypass the duel feed changeover board to just attempt to get the Y power feed working through the Quinton Crane control board just to eliminate the duel feed board

I am not sure how to add pictures? But will post some photos as soon as I know how

Many thanks
Marc
