    Help to ID engine

    A friend of my father-in-law was going to pitch this in the dumpster while cleaning out the basement of his business and then remembered that I mess with this sort of thing. After a lucky save I'm trying to ID the engine. It has a 7.6" diameter flywheel, bore of 1.4" and 2" stroke. Any help...

    Collet Sets

    I have two collet sets that I figure someone on here may have use for. First up is a Pratt & Whitney #3. The sizes should be visible in the photo. I'd like $50 for all of them. Second is an Erickson 100DA set that still in in the shipping cosmoline. It is missing the 1/2" collet. I'd like...

    Sets of riffler files

    I don't do paypal, sorry. Answering other questions, they are US made. Also note they are the larger 7 1/2" long ones, not the smaller size. Thanks for the interest. Steve

    Sets of riffler files

    I have a few sets of these files available. They include Nicholson Style 3, 6, 9, and 12, and two AM Swiss Style 10, all in cut 0. These are NOS and in pretty nice shape. They are $25 for the six files. They can ship USPS priority for $5.86 in the small flat rate box. Steve Roskowski 317...

    Bill, It started out great, but this past spring and summer wound up kind of rough for me on several fronts. The last of the issues was the bonus of enjoying a 100 year flood that wound up with about 8" of water in my shop. Here are a couple of photos. They were after the torrential rains...

    Now that we have trued up castings, machining can move forward to get it to be a subassembly. The next step was to mount the front plate in a four jaw chuck and face off the mounting spigot that goes into the crankcase as well as its mating flat surface. As before I used a center in the...

    No crash that time and it all stuck! Looking at the castings it seemed the the round boss inside the front cover was favored low in comparison to the crankcase. I put it under the crankcase aligned the two and then drew the ID onto it. The photo shows the offset. Since I had the plug to locate...

    That was really strange. I didn't do the manage attachments and the photos were still there from the last try. The session crashed, but the stuff stuck. I will try to move on to the actual facing operations once we have established the flat datum. The first ones show decking the front...

    I am trying this again. For some reason the site crashes when I attached photos. I am making progress again. I am doing things a bit differently from the method that Juraj used on his initial engine. He glued the parts together with epoxy to gang drill the holes all at one time. I made...

    Things have been a bit slow around the shop with some house projects taking precedence. I am working on the crankcase cover and the sideplates opposite that carry the main bearing as well as the cam gearchest and cams themselves. Stay tuned for some new posts coming soon. I should have these...

    Hot Rod Arbor Press

    Last year while using a "top of the line" Harbor Freight arbor press, I wound up having a broach wind up shattering. The wobbliness of the press was the largest contributing factor. In the broaches defense it knocked out probably around 100 or so 12mm square holes in 1 3/4" couplers for boat...

    We are doing this build as a verification of the castings and proofing of the plans. Rather than have Mr. Kadora offer the stuff as not verified, we are going to complete this build, make any necessary adjustments and then I'm sure he will be offering the stuff for sale. Please be patient and...

    Once the features were completed on both faces it was time to make a home for the cylinders. I put the crankcase on the same dowel "hangar" and then leveled it with a digital protractor. I double checked the level by using the feeler gage between the deck and a mill cutter. A slight tap with a...

    It may sound somewhat corny, but my rotary table is a special tool to me. My dad's best friend gave it to me about 10 years ago. Alex was actually who inspired me to get involved in machining and doing things just like this. Every visit to our house was accompanied by books or magazines for me...

    I was able to proceed with some more work on the crankcase as for cutting the cylinder decks, tapping the holes and boring out the cylinder bores. There are multiple ways to attack the next steps. One is to do it on the mill. For this method I am showing the setup for the flycutting the decks...

    The one running was simply glow ignition. It can be adapted to anything you would like though. I may do mine as a battery spark. I did get help getting the rotary table on the mill and made the centering spigot for the crankcase last night. I will get more work done on it this weekend and...

    Kadora, the designer and builder of the first one has. I am simply doing a build forum for him as English isn't his first language, although from all my correspondence with him you wouldn't know it. I'd say his grasp of the language is better than many Americans you meet in public these days...
