    I change the direction of the power feed (cross to longitudinal and vice versa) under power all the time. There really isn't any problem doing it, because of the slow speed of the drive.

    Now, the...

    I imagine that the speeds listed are for a factory installed motor and pulley. If an end user installs their own motor and pulley, especially pulleys of different diameters, the ratios will be the...

    I guess that it is what you would call complete, as it shows all the speeds available. Here's the chart from someone's posted .pdf of HTRAL. It is from the 55th edition.

    Why did you add the Gitts oiler on top of the bearing block? The spindle lubrication system is one of the few on a SB lathe that isn't flow-thru.

    There's a chart in HTRAL that gives the approximate spindle speeds in RPM. It's on page 23 of the 56th edition. It shows the top speed of a 16" to be around 980 RPM, so you may be just fine. And...

    This is what I did when I recently made some spindle nose protectors for Heavy 10s. You have to make it as near identical to your spindle as you can! This will mean many measurements over wires as...

    Yeah, it's the three slotted screws holding on the back plate. Take them out and put in their place threaded rod (that matches their thread) as far as they can go and tap them in a sequence to...

    Yeah, mine is kinda crude. There's just nothing like 35 to 40 pounds of chuck suddenly becoming free from your spindle. At least we don't require a crane to put on/pull off chucks like Abom79 does...

    The model number indicates a tool room model, thus it should have a taper attachment.

    BTW, a 14½" lathe will require a 12" (or greater) level. You'll want accuracy of 0.0005"/10", which is 0.05mm/m, or better.

    I thought it was a "buy-it-now" offering. You're right, the price will probably go to $120.

    I think you mean "mounting plate". The spindle thread for a 14½" is either 2¼-6 or 2⅜-6, depending on the bore. Neither of these should be hard to purchase. A mounting plate is shipped (new) with...

    It's not a problem. Some people have replaced all their cheesehead screws with SHCS. The only problem with a cap screw, is that the hole will hold turning swarf. If they stick up too much for your...

    Jim has given some pretty good instructions.

    I would add:

    1) A belt sander also makes a good device for tapering the two cut areas. Make sure you taper the TOP on one side and the BOTTOM on...

    For any SB lathe with an undercarriage drive, cutting and gluing the belt is the ONLY way it can be done. There is no way to install a continuous belt on those.
