    draw bolt rod

    Glad to be of help. For the ones that are concerned about alignment of a weldment: one can always turn a ”pin” on one part and a close fitting socket on the other. Chamfer each well (weld prep), stick them together and weld around the circumference. Turn down the excess weld and you should have...

    draw bolt rod

    How about a grade 8 bolt (or similar strength) welded onto any type of steel rod? As has been mentioned, it is the threads that take the most abrasion and thus lose form fastest. If they wear out, cut off the bolt and weld a new one on. You’d be back in business right away.

    Places like that are beyond cool. Thanks for sharing.

    Hopefully I understand you correctly… you are saying that if you were to take off the nut (red arrow) , you can not just slide the combo gear off the shaft and turn it around? Have you tried it? That gear has a 6203-2RS bearing in it. The axle runs through the inner race. The bearing / gear...

    @Brian H : do you mind doing a little experiment? 1) can you take the 91T/86T combo gear and turn it around 180* on it’s shaft so that the 91T portion is closest to the headstock (opposite to the way you have it in your picture in post #13 above) 2) mesh the 45T ”F” input gear with the 91T...

    I believe those compound gears are used for feed reverse. Looking at the main gear table in the manual, both are 45T/40T (40T/45T) combos meshing with a 45T on the spindle. I would think that it is physically impossible to install them “backwards” because of their size difference.

    Is this how you measured the 1” carriage travel when you did your “pitch validation” as you posted in #68 above? I can see your method to be a bit problematic: a) typically, one does not use a 1” capacity DI to measure a one inch distance; you should use a 1.5” or 2” capacity one b) the...

    WTB: Prvomajska Milling Machine

    Hi Andreas, welcome to the forum. We met at the auction just south of Olds a few weeks back. You were getting ready to load out the lathe while is was waiting for the forklift to move the pallet of steel by the mill. If you can make it, we have a meet up at my shop on April 20. You are welcome...

    I noticed that as well. My guess would be for our friends running 50Hz motors to get the spindle speeds as posted. At any rate, the location of these “alternate” gears do not influence in any way your threading problem as they only affect the spindle speed itself.

    There is a discrepancy between the King instruction chart and the Grizzly reference table. King instructs to mesh F-gear with 86T of the compound 86T/91T. The Grizzly table tells us to “always mesh the F-gear to the 91T portion” of the 86T/91T combo. King chart: Grizzly table: We know King...

    The KC–1236 does not come with a 127T transposing gear. They use an approximation with the 86T/91T combo. I believe @Brian H ’s change gear setup is correct for the required 1.5mm pitch. He also just confirmed that the threading lever 4 is in the correct position. Therefore either something is...

    Also from your manual: make sure lever 4 is in the threading position vs the power feed (turning) position.

    Thread indicator for Clausing 100 Mk 3 lathe

    Maybe they were stripped out and thus the dial went AWOL? Or a threading dial was an option and the hole is the taping drill size for the SHCS? Since you are making a dial from scratch, you can choose the bolt size to fit the hole you have after you re-thread it or repair it with a helicoil.
