Hi everyone. I recently sold my Alpine minor mill ( clone of RF25 etc) which I had owned for 25 years & bought a Chester 626 mill. I had retained an Align power feed which was bought from Axminster tools as it was nearly new & 240 volt. This clamps horizontally on the left hand side of the table unlike the 626 which hangs vertically on the right hand side. I saw no reason in principle why my unit couldn’t go on the left hand side horizontally, saving me several hundred pounds. The only problems were that the original clamping bolts were too far apart for the 626 table, necessitating an adaptor plate made out of 10mm alloy, countersunk for longer hex bolts & tapped 8mm for bolting to the power unit. A second problem was the differing diameters of the leadscrews, 17mm for the old mill & .625” on the 626. This was simply solved by making a bush & pressing into the gear. I could have bored out the gear & turned a larger bush, but I wanted to keep it standard. The grub screw already in the gear fitted into the keyway providing a weak point in case of any table jams.
The power feed now works perfectly, & apart from increasing the length of the table, appears to be just as good as the vertical unit.
I see that there are other units for sale on eBay cheaper than the Align units, but they are still 110v requiring a transformer.
