    1950 South bend lathe restoration.

    I have the apron and saddle fully assembled. Sadly the previous owner did some heavy modifications to the handle side of the cross slide lead screw. I did my best to fix their handi work. I replaced the cross slide brass nut also. To my surprise the cross slide only has .005" backlash, and...

    Bench mill column

    Anyone check how square their column is with their table on their bench mills? If so is there anything you did to straighten it up if it was out? I have a precision Matthews pm-30-mv that has been converted to a CNC mill. I was able to put a tall granite square on the table and check the...

    1950 South bend lathe restoration.

    1950 South bend lathe restoration.

    I've been wanting to replace the belt myself. I saw some glue together belts online, but they are pretty pricey. That sounds like a good alternative! I bought a new cross slide nut as the old one had a lot of play in it. I think I figured out a way to make an antibacklash mechanism utilizing...

    1950 South bend lathe restoration.

    A couple of years ago my dad and I were able to pick up a 1950 south bend 9a lathe. It was in really good shape for it's age, but at the time I didn't have room for it. It sat under a tarp in my dad's woodworking shop collecting dust literally. I finally have the room for it, but I figured...

    Shop equipment options

    He used centroids acorn board with centroid cnc12. The spindle still isn't hooked up to the CNC. When I do that I may add an encoder since the board allows for one.

    Shop equipment options

    I bought a mill this week! I have been debating the bigger vs smaller for awhile now and decided to just wait until the right one comes up. It's a pm-30mv that the guy turned into a CNC by himself. His job has him building plc boxes regularly, and you can tell. The mill has also hardly...

    endmill

    Typically if you use an end mill to bore out a hole it will cut bigger than the end mill size, so even if you find the end mill you are looking for you may not be happy with your results.

    Measure internal taper

    I would probably indicate the bottom if I were you. You can put the indicator on the bottom and then use the x axis to find the low point. You don't necessarily need a full inch of travel to figure this out. You could trynto move a half inch or .25". The only issue is .002 is already a small...

    Measure internal taper

    When measuring make sure you are on centerline, you will get an inaccurate reading if you are off of center.

    Press fit dimensions?

    An interesting debate going on. Although I can achieve the same precision at home as I can at work (to a certain extent) I find it much easier at work. Many hobbyists are using used equipment from schools or long closed job shops which sets you up at a disadvantage right off the bat. That's...
