Need to take a 510 down to its component parts for complete restoration. Cannot remove the carriage lock assembly. I have driven out the roll pin that retains the handle to the threaded shaft, but cannot remove the handle. Have soaked in penetrating oil, with no luck.

Is the shaft threaded on to the handle, or just press fit?

Any suggestions are appreciated.

Yes, the handle is threaded onto the rod.

AND a left hand thread(righty loosey lefty tighty).

Has a nasty habit of getting stripped.

I can understand that; penetrating oil, heat, torque, no progress.

For sentimental reasons, I was trying to keep it as original as possible. Looks like that won't work. Can't get the way tubes out of the hinge casting either. Bummer.

On some older machines the way tubes are held by set screws . To find them, set the casting into the upright position and look up through the casting web. ( up from the "bottom" ) The screws are visible but you may have to use a bright light. I have had a few that were difficult and I had to resort to strap wrenches to get them to move.

Is there a difference in design between the older units and the newer ones.

Are we discussing Carriage Assembly 514328.

Is it absolutely certain that the handle handle needs to come off of the rod to do what is needed. It does NOT have to be removed, at least not on mine, to remove the rod from the carriage.

Now there is a nut at the other end that needs to be removed but it is NOT a reverse thread. Here again, is there a difference between older units and mine.

All models retain the way tubes with set screws. The newer ones are on top. The older ones are behind the hinge pin. They s/b serrated cup, so the tubes will not slide out easily due to the set screw scarring the tube.

Have removed the set screws, but the tubes will not budge. They were immersed in water during a hurricane, and bimetallic corrosion is the villain I believe. Have soaked in penetrating for months, heated, broken 2 strap wrenches, and have run out of ideas. What kind of business could provide assistance; machine shop? Getting to the point in the restoration that the tubes will need to start cooperating.
