    Induction forges

    I don't think temperature is controlled with an induction forge. They are most often used for melting metal in a crucible that sits in the coil. Frequency can change the induction which would change the temperature, but I don't think it would be very accurate. I use the heater mostly for...

    Induction forges

    I've gone back to my induction heater project. The previous 2500W module stopped working, so I ordered a replacement module which is 3000W. The power supply is 3000W but I can tell that it's working far too hard byhow fast thefan is running even when the module is only drawing about 1Kw by using...

    2x72 sander

    I'm not sure if I've already shared this, but I've definitely improved my belt grinder both in terms of electrical and mechanical operation. Instead of using multiple square tubes to build the frame, a single large rectangular tube was used to keep everything in line, and the adjustable...

    Drill press repair

    The remaining amount of the taper that you see is excess taper where the rest makes full contact inside the chuck. The draw bar was long enough for me to cut off the end od the taper up to the point that made contact at the top of the chuck. From there I machined the draw bar to make full...

    Drill press repair

    I managed to shape more of the drawbar to fit more of the face of the arbor against the inside of the chuck to hold the chuck securely in place collinear with the draw bar.

    Drill press repair

    The spindle is hollow. One long tapered draw bar runs up the quill through multiple pullies on top. I don't know if any of the drawbar could be removed and still remain inside the pullies when drawn all the way down.

    Drill press repair

    Yeah I do have a lathe, and I tried using it to shape the arbor. I did get it straight, but the arbor didn't have enough material near the end to make contact with the chuck. Only about 1/8 an inch on the top of the arbor makes contact with the chuck which is what allows the chuck to move easily...

    Drill press repair

    The arbor on the end of the shaft of my drill press is in terrible shape and doesn't hold the chuck well enough to keep it at the center of the shaft. If you look at the original arbor in the first picture the arbor is part of the shaft, so it is a tapered shaft. In this case I will need to cut...

    Tubing roller

    That makes sense, just the same idea as a hydraulic press with the use of three round dies.
