    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    The footplate serves as the basis for mounting the boiler, cab and burner assembly. It also provides additional rigidity to the rolling chassis. By this point a few errors have probably crept into the Regal chassis, making it difficult to fabricate the footplate in one operation. Do the...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    Hi DW. The short end of the wiggler goes into a center punch spot on the work piece. On the cylinder, it was a very small drilled hole. As you rotate the chuck by hand, the center error on the work piece is magnified by the wiggler on its long end. So if the short end of the wiggler is 1...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    With the cylinder block centered in the 4 jaw begin drilling out the bore. Step drill with about 3 or 4 drill bits to 3/8". Then switch to a boring bar. Take several light cuts until the bore is about .010" under 7/16". To size the bore exactly to 7/16" use a reamer in the tailstock chuck...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    The motor for Regal is a single cylinder, single acting oscillator. The bore is 7/16" with stroke of 5/8". Oscillators are easy to build and very powerful. "Chip" is the first oscillating locomotive I built, its been running strong for years. Here is Chip at the National Summer Steamup, I...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    The flywheel is a two step turning job. Here is the drawing: Any metal, except aluminum will do for the flywheel. Aluminum is probably too light. The flywheel has to be a bit robust or the engine will run very "jerky" on the track. This flywheel is bronze. Chuck a 9/16" length of...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    The wheels on Regal follow the Gauge One Model Railroad Association (G1MRA) recommended practice. G1MRA's practice is available from their website. The G1MRA practice calls for a 3 degree taper on the wheel rim and 20 degree taper on he outer edge of the flange. Wheels can be either steel...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    Make the end beams from the same material as the frames. Here is the drawing for the end beam and other parts used in this section. Use the same general method to make the end beams. Regal uses a brass screw in eye hooks as couplers. Drill the end beam exactly in the center for a tight...

    "Regal" 0-4-0 Oscillator in Gauge 1, Progress and Updates

    Many years ago I built a Gauge 1 version of Ernest Glaser's "Cracker". Cracker, originally Gauge 0, is a single cylinder, gear driven, single acting oscillating engine with a gas fired boiler. Here are a few examples of Cracker. The plans for Cracker are available at...

    Cutting Spur Gears -- A neat technique

    I did not mention it, but my forming cutter is 30 degree total for a 15 degree pressure angle. The forming tool was made using the "V" notch in a screw cutting gauge as a guide. I guess that's close enough to 14.5 degrees. I had no idea how many faces to put in the cutter. It has 8 (?)...

    Cutting Spur Gears -- A neat technique

    Thanks Al. The 16-tooth pinion cuts in the same general manner as the 52’s. The notable difference is that the hub is integral, rather then hub less. Change out the 52 tooth indexing gear on the dividing head and replace it with a 32 tooth. During machining, skip every every other tooth...

    Cutting Spur Gears -- A neat technique

    Several years ago, I did a series on cutting spur gears using the methods in the “Workshop Practice Series” book #17, “Gears and Gear Cutting” by Ivan Law: Mr Law's method works great. You can follow his techniques without deviation. However, recently I found another...

    Editing an old thread

    In May 2011 (5/16/2011 to be exact) I started a thread on Harold Hall's basic dividing head. I plan to re-do that build, so I would like to update the original thread with new photo links. How do I edit that thread? Did not see a way to edit (unless I missed it) Thanks, Bob
