Shaper problem

Also pull apart and check the ratchet feed mechanism. Maybe somebody previously has been in there and things are not as they should be. When you've got that far, check the feedscrew end float (Should not be any), taper locating pins and thrust bearings if any.

Mike.

Thanks Mike - I have doctors this morn but last thing I tried yesterday was to try and dismantle the ratchet end before trying to remove the feed screw. Before I did that I removed the retaining nut and lock nut from the other end of the shaft. The ratchet cog itself has a cross head retaining screw bearing down on the shaft but sometime in the past someone had naffed the screwdriver slot on the head of the screw so the only thing for it was to drill out the screw in situ.

That done I attempted to remove the ratchet from the shaft by engaging the ratchet pin and winding the handle the wrong way. Only with the greatest effort was I able to move the shaft within the bore of the ratchet. Conclusion? It looks like the ratchet has been pressed on. Humbug!

Had to go down and have a look.

The cog is a sliding fit and the rachet rides quite loose on the shaft.

Took a cell phone pic with both removed.

Today I managed to remove the traverse shaft which sidestepped the problem of the pressed on ratchet after which it was a simple matter to detach the cross slide and pick up the drive nut where it had dropped of.

After a thorough clean and lube I could see that the drive nut had taken damage over the years at one end of the thread.

I was able to thread the nut onto the shaft from the good end of the nut and all was well until the shaft thread approached the damaged end where it became very tight. I had found the cause of the mystery tightness.

What I really needed now was a bloomin' great acme type tap to clear out the thread in the nut but.....!

As I pondered my next move it suddenly dawned on me that my "tap" was staring me in the face in the form of the threaded shaft itself. With the nut in the vice I dolloped some coarse grinding past on the end of the shaft and with a few turns using the handle on my "tap", lapped the nastiness away. A quick sluice with white spirit and a re-lube and I was able to spin the nut down the shaft with zero resistance. Oh happy, happy day!

Rick,

Nice bit of lateral thinking there.

A relief when things come together.

Another solution would be to cut a groove across a few end threads so that they act as a form of cutter.

I've done this on many occasion when cleaning out/tidying tapped holes, and it works a treat.

Geoff - Back on the FeedRod motor now that all machines are up and running.

Yngvar - Thanks for the pics. Your machine seems different to mine. Mine is the "NEW ALBA 1A". I have a copy of the Elliot 10M Operators Manual which shows an exploded view of the ratchet assembly and it has components that my machine does not. Even the clutch handle is different. I suspect that you have the Elliot 10M - have you?

I can only repeat that the ratchet cog on mine - even with the securing/safety screw drilled out is virtually unmovable on the traverse shaft - it was almost certainly pressed/shrunk onto the shaft.
