Well I put the new metered oilers in and tested them. I'm not getting oil to the outlets for the table ways, despite checking that the ports are clear. I decided that as these face upwards, the path of least resistance is with the oilers for the saddle ways. I'm hoping that once the saddle is on and the gib adjusted that oil will then flow upwards. So, in order to do this, I needed to drill the roll pin holes for the yoke from 6mm to 8mm to accommodate the new yoke I bought.
This necessitated some creativity, as the drill press table isn't exactly large and the saddle is heavy. These are all the ingredients you need for disaster! So, I moved the drill close to the mill, and then places a thick piece of wood across the knee and the drill table. Using a level, I cranked the knee until it was at the same hight as the drill table. Next I positioned the saddle, using a 6mm drill to locate the existing hole and then clamped the saddle down. After checking the location again with the 6mm drill, I drilled the saddle with a 7.5mm drill before finishing with an 8mm drill.
I then noticed that the actual bolt holes are slightly off on the left-hand side of the yoke. The M8 is very tight and I couldn't get the 8mm drill in the location hole as a result. The M6 is more of a problem.
I still need to pick up some 8mm roll pins (I'd like to buy less than a box of 500). and use them to locate the yoke. I'll then check how far off the holes actually are. That will determine my approach to that issue. For a moment there it was looking closer to completion.
I then turned my attention to the quill feed and went from having feed but no trip activation, to not having feed, nor trip activation, and then to feed with weak trip activation. Part of that was me adjusting the clutch the wrong way and because I was making slight adjustments I didn't realize until I'd gone about a turn and a half in the wrong direction
Part of this may be due to the quill spring, which I have no idea what is going on with. Before the evil noise induced tear-down, I had the spring adjusted perfectly, with the quill staying exactly where I positioned it. I followed the Bridgeport setting instructions and it worked. Not this time however! The only thing I can think of is that the spindle that drives the quill was in a different position, either 90° or 270° off, as there is only 180° of adjustment of the spring. The PAITA about this is that the motor, belt housing and back gear assembly all have to be removed, so that the two screws connecting the quill skirt to the quill can be undone. Oh well, no point rushing things now.
