Boring Head - Test Cuts in Steel Pipe
Переглядів 22614 днів тому
After finishing the Jig-Bore style boring head, I wanted to do some gentle test cuts in steel, so I repurposed a scrap piece of Sch 40 4" pipe. In the worst steel imaginable, the boring head did pretty well, so it's on to the actual machining of the Rockwell Radial Arm casting.

    Howdy from central Michigan. I have a Dawson, evolved into Royal Oak. My tool head is crude in mounting and or missing a tilt table. So that needs to be made. I hope to learn all i can from you, as my Grinder unit is decent quality and condition. Sadly my air bearing seems to be designed for a right of the wheel travel, and my grinder table is designed for left so i need to make a table extension i guess. I would buy a different work head, but i have all the cams for it, the locating rings and a full set of collets including squares and hex, and a face plate with many mount points drilled, and a 3 jaw chuck. Howdy from central Michigan. As an added bonus, my themac7 tool post grinder mounts on the rear of the grinder tower, which rotates 360 degrees. So i can really cut any angle, or helix grind, but... still a ways off from end mills and drill bits.

      It was the condenser from my parent's original A/C. Had all the parts mounted on a galvanized pan under their rear porch. Wish i saved more of it, there were cool things like brass sight glasses, 300 psi accumulator tank, etc. Still like your bearing conversion idea, will do that on the other motor when I'm not under the gun to get it fixed so fast.

    The LED upgrade of the old flourescent fixtures will be really nice. For the HVAC blower motor, when mine failed in a similar way, I took out the oilite bushings and turned aluminum adapters to hold sealed ball bearings. No more needing to oil the motor and quieter. After that unit was replaced, I kept the blower assembly and used it for my attic fan as it was much quieter than the crap propeller fan. It didn't need to make any static pressure, so it ran cool and used less power than the prop fan. Used that for 12 years and took it with me when I sold the house. still works fine and will use it for the exhaust system on the new shop eventually.

    • @EngineersWorkshop
      @EngineersWorkshop 3 місяці тому

      I hadn't thought of a bearing conversion, might be an option here. We're using this for our heatwe in the barn. The old AC condenser is copper coils so we run the boiler water through it.

    • @EngineersWorkshop
      @EngineersWorkshop 3 місяці тому

      Thanks! No, torque and stretch of the rods locks them in place. No vibration here, double nuts are often misapplied where vibration is suspected. There are no double nuts or lockwashers in engines, such as connecting rods and mains. The clamp load alone through proper torque keeps them in place.

      @garychaplin9861 3 місяці тому

      @@EngineersWorkshop I will be interested to see if it does make a difference. I think it likely that the extra distance that the cutter is from the spindle will tend to counter act the effect that the extra mass provides. As a side comment, the joint between the shank and the main body of the Bridgeport boring head is a fine thread and is probably the weakest point of the boring head. I agree with your opinion that they are a nice head to use but in my opinion, not a good head to use for heavy or interrupted cuts.

Long term i'd like to make a shank sleeve held on by a cap screw that increases the size to 1-1/4" or so. Won't be able to use it in the 2D then, but my Rosenfors mill has 50 taper holders for bigger stuff.
