Re: Bringing Boyar-Shultz 612H back to life

With all the adaptors and spare motor I gave him a little more than he was asking. The drill is a small taping machine, someone gave me it, and I put it away in the container thinking it was a drill. Found a post somewhere showing what it was. The table moves up and down, with a ratchet handle. When...

Re: Bringing Boyar-Shultz 612H back to life

Thanks for the timely info in your post Conrad. I just picked up a 612, but I think older machine in really good shape. Mine has a belt drive, I've seen mention of these but any literature shows the direct drive. The spindle on mine uses two deep groove bearings the rear one has the Belleville washe...

Re: File cleaning

There was a container of File Sharpener at the local hardware, been there for years so he pretty much gave it to me. Think it Phosphoric acid, it actually seams to work. The file isn't like new after a soak, but better than dull. I use a piece of flattened copper pipe pushed across the cut of the fi...

Re: Heating and bending metal. Need advise

You'll get it around the pipe that way but the bend may not be real smooth, a little too much heat here and there and that section will bend more than beside it. If you can get access to a slip roll and bend it cold you'll get a far smoother bend.

Re: Engraving Bit

These graduations were done with a cutter I ground, should have twisted the spindle to show the cutter profile.

Re: Engraving Bit

I've had good success making cutters like this from broken carbide drill bits.

Grind to a point as you did then grind away half the thickness.

Re: Best Tool to Remove Small Concrete Hump from Floor

If you have a 7 inch angle grinder one of these cup wheels will eat concrete. http://www.homedepot.com/p/RIDGID-7-in-24-Segment-Turbo-Cup-Grinding-Wheel-HD-TAW7024P1/202884372 I've rented them before I finally bought one. You can try and run it wet to keep the dust down but you pretty much need a ga...

Re: Turning 1" axle between centers

For the lathe I keep the cutting edge straight, it only contacts the work at a narrow point anyway. With a straight edge I can raise and lower the tool to get a fresh edge. For the shaper it needs a rounded end to only contact at a point in the middle of the cutter.

Re: Inexpensive small machinist vise options?

Not sure where to look for one but this is by far the best drill press vice I've ever seen. The clamp on the arm can be cinched down or left loose to position the work, either way it carries the torque of the drill. There is a step in the top of the jaws to hold thin work flat and off the table for ...

Re: Turning 1" axle between centers

Glad it worked for you Glen. Maybe try a little more angle from the vertical, but if you go too much it starts to roll the chip rather than shear it.

Re: Turning 1" axle between centers

I'll have to respectfully disagree with you Russ. Its my go to cutter for long slender shafts. It will even remove a chatter pattern thats developed. Needed a smooth finish on a 2 inch shed 40 pipe for a make shift grinder head to index sideways on to rough grind concrete counter tops on my sawmill ...
