    Longboy's "THREE BELOW" Model Engine.

    Hi Longboy, Very nice tip on using painter's tape. I really admire your work and watched the videos on your you tube page. The remote valve block concept looks radically different than what I have seen. Could you explain how the intake valves and block work? Is it similar to hit or miss engines?

    1916 65 HP Case Traction Engine 1/16 Scale

    Very tedious and repetitious work. I finished making 36 good grouters with 4 rejects and two spares. Cobbled up a rivet cinch and set along with the lower anvil out of 1/4 0-1 tool steel. Made a few trial length rivets and settled on 0.375 length as best. A scrap piece with a 0.350 deep hole...

    1916 65 HP Case Traction Engine 1/16 Scale

    Hello again, the grouters on the original Case tractors were drop forged parts and either bolted or riveted to the rims (not sure which). I have seen pictures of double cleated chevron pattern and single cleats like the picture I am using. The number of cleats varies, but I am going to plan on...

    1916 65 HP Case Traction Engine 1/16 Scale

    You are welcome Wheat47, I believe there wouldn't be near as much twist if I had used regular silverbraz 55. You are right about the order of operations. Definitely braze the spokes into the hub first as they are free to expand outward into the through holes in the rim. I also left the rims wide...

    1916 65 HP Case Traction Engine 1/16 Scale

    Thank you Green Twin, I'm going to try and take my time on this build and add some extra details Thank you Johnmcc69, The cleats are going to be tedious the way I'm building them but I think it will look authentic. Here is a model that matches the rusty old image that I'm using for detail work...

    1916 65 HP Case Traction Engine 1/16 Scale

    Hello again, Completed the other front tire and started the rear tire. I continued the all steel approach as brass is really expensive and I didn't see a need as the plan is to paint them red. First I CAD rendered a "realistic" wheel with my interpretation of the cleats or grouters and a...

    1916 65 HP Case Traction Engine 1/16 Scale

    Hello, New project is a 3/4 inch per foot scale model of a Case steam traction engine that is located nearby at a fairgrounds in central Florida. I never gave much thought to these tractors until a colleague at work told me about the Case 150HP that was recreated in the Midwest by a young man...

    Muncaster Joy Valve Steam Engine 1/2 scale

    Good eye KVOM Yes I was holding off on drilling the lower mounting hole until I completed the reversing wheel. It runs on air and reverses direction so I disassembled everything, drilled the exhaust hole and made the exhaust pipes and elbow. I only made a top cover gasket thinking that I would...

    Muncaster Joy Valve Steam Engine 1/2 scale

    I was also thinking of that because I have been researching Case Steam Traction Engines as the next project, and that's what they used. Never knew it was called a Johnson bar. In construction, a Johnson bar is a heavy metal bar used for prying on and digging out rocks. I thought the name was...

    Amazing work Foketry, How was the mold for the flywheel removed from the sand?

    Robs Howell V4

    Hi Rob, I used this coil on a TIM-6 ignition for a small V-8. Trimmed the fat spark wire near the coil tower and soldered a smaller gauge hi voltage wire to it. Used a few different sizes of heat shrink to seal everything up.

    Muncaster Joy Valve Steam Engine 1/2 scale

    Thank you for the likes and comments Estimated the radius rod at 4.050 by centering the valve over the steam ports and measuring from the valve spindle eyelet to center of the trunnion, and then followed your lead on the radius in the curved trunnion blocks. I believe there is a lap of 1/8"...

    Muncaster Joy Valve Steam Engine 1/2 scale

    The next parts to make are the little guides that run inside the milled arc on the brass "shoes" and the potentially ignominious upper links. The upper linkages are not dimensioned on the Muncaster plans. Most probably due to numerous dimensional tolerances that affect them working correctly. I...

    Muncaster Joy Valve Steam Engine 1/2 scale

    Hello again, Last weekend I made the valve rocker "shoes" out of a 1/4" piece of scrap brass shim-plate. I sure hope that the estimated radius of 4.050" is correct as several pieces will need to be remade if it isn't. Milled the radius slot on the rotary table on both sides because of the...

    Muncaster Joy Valve Steam Engine 1/2 scale

    Thank you Peter, Coating more of the part and using insulated brick helped. Have to order some real insulated fire bricks, this stuff is actually calcium silicate pipe insulation and it falls apart above 1000 F. I think I had the torch cranked up too high previously when I did the valve rocker...

    NYLON MILLING MACHINE GEARS

    here's how it looks installed, with the stock motor cover removed. The cover needs to be raised about 1/2" so the belts are aligned. I made a thin spacer to cover the gap.

    Muncaster Joy Valve Steam Engine 1/2 scale

    Thank you for the comments and tips. I will try the white flux next time, seems I was misinformed about the dark flux by the label and other forums. I think my new "hard" fire brick may be robbing some heat input as well. Steamchick suggests the insulated properties have a large effect. Perhaps...

    NYLON MILLING MACHINE GEARS

    Please refer to the below material list for toothed pulleys and hardware that was used to convert my G0704 mill about 2 years ago. I was stripping the gears also. There is a compromise because I lost some top end speed, to gain low end rpm. I believe there is some improvement in surface finish...

    Muncaster Joy Valve Steam Engine 1/2 scale

    Hi Peter, I used Harris STAY-SILV black high temperature flux, Harris SAFETY-SILV 56 brazing alloy and map gas turbo tip. I had success earlier when brazing small components such as the 5/32 SS valve spindle on this project in an earlier post. Copper and brass seem to be no problem. I brazed the...
