Chester 626 mill power feed install....
<< < (2/5) > >>
John Rudd:
So having got the mounting holes done, time to try the powerfeed....
The holes line up perfectly...
John Rudd:
Now there are more issues.....

With the bearing block back on the table, the leadscrew has a shoulder some 20mm in diameter.
In the pf unit, there is a needle bearing, a sleeve takes the shoulder diameter up from 20 to 24 mm which is the bore of the needle roller......
John Rudd:
The sleeve is not long enough, and neither is the 20 mm diameter shoulder of the leadscrew....
As the pf unit is offered to the leadscrew, the sleeve slips backwards resulting in the pf falling onto the leadscrew....
John Rudd:
So now I need a workaround..... :dremel:

I could make another sleeve that will fit onto the leadscrew, stepped to accomodate the existing 20mm shoulder, with an o/d to suite the needle roller, then a further section machined to accomodate the bevel gear...

OR you guys could suggest an alternative? :lol:

I'm going to call a halt to things at the moment while I have a think..... :scratch:

Stay tuned for more ramblings and metal mangling....

There are two locating dowels in the end bearing support.....look how well installed they are!
The square gives an idea of how far out they are....

Hi John,
The dowels on mine were fine, yours do look very badly out of square.  Also the dowels on mine had a threaded hole in them, presumably so that they could be jacked out with a screw and a collar.

I returned the power feed that I bought, which is why I decided to build my own.
