Shaper problem

<< < (2/2)

Joules:
Yep you have run the nut off the leadscrew.  To protect the table from crashing and stripping/wrecking the nut.   Simply push the table at the opposite end and wind the nut back on the leadscrew, this how my Elliot 10M behaves.

Chrispy:
AMMCO shapers have the same setup. The threads stop just before you would have a part breaking bind up. Made for folks just like me.  :drool:

Joules:
Get yourself a soviet wife....  One who has done some weight lifting  :bugeye:

Actually you could try putting some studding down the centre T slot with a steel plate on the end of the studding then fashion a lever to contact the shaper some where you can lever the studding without damage.  That will put a heck of a load on the table.  Spray as much lube as you can into the slideways.  Take it steady as you go, if things start bending STOP, don't take them to breaking point.  Gentle tapping with a copper hammer won't harm either.  If its as tight as you say, you could well have stopped the nut.

Sorry for resurrecting a dormant thread, but I'll add my 2 pence worth for anyone trying to sort out a similar problem in future. mcostello and Joules are spot on with their explanation. To solve the problem, my first approach is to place a block of wood against the side of the table and whack it with a hammer to bring it up to the lead screw. If that doesn't work, I dismantle the lead screw and move the table just enough to re-engage when reassembled.

More importantly, I find that if it dis-engages while on auto feed, simply reversing the direction re-engages it as long as you don't move it manually beforehand. I have purchased one of these http://www.igaging.com/page21.html to use as a DRO so that I never have to use manual feed on the table again.
