It's hard to believe this is #80 video of my shop at work to show you how line shafts, steam power and old method machine work was done 100 years ago. This one continues with the fabricating of a gear box shaft for a round hay bailer, a new design cross head for the Liley steam engine build and some clips of work in the front "engine" shop. As always, comments questions and discussion of steam power and old school shop work are always welcome. Thanks for watching.....Dave

So glad to see a new video. Always enjoyable. Years ago I on occasion would run a large open side planer resurfacing cast iron ingot molds. Using the side head I would get a long "beard" of chips and dust hanging down from the tool. Everything was magnetized. We used 1-1/4" x 1-1/4" x 9" tool steel bits. Love the channel.

That crosshead is a real piece of work. I think you are right, the bearing journal was made first and the cast into the head. Is the journal made of steel? They would have locate any machining off the journal because they could never place it in the mold with that level of accuracy. Sounds like a nightmare, glad I am watching you do it instead of me.

I just found your channel David. You do great work and I really enjoy the videos. You remind me of a guy (also from NY state) who taught me basic skills on the lathe back in the 90's. State highway shop so we worked on a lot of large trucks and machinery. The shop had a several old lathes and milling machines that came from battleships and other Navy vessels that were decommissioned after WW2. Before I left that job, I was able to snag bench vice made by Reed Manufacturing Model 104 1/2. I believe it also came from one of the decommissioned Navy ships, and I still use it today. From my research, the ships that were decommisioned after WW2 were mostly built in the 1920's, so it's the oldest tool in my shop by far.

I run into magnetized chips and parts too sometimes. We always had some sort of an electric demagnetizer that we would run over the part to fix it. I liked what you did with the old 390 FE heads too. I think when I had my 360 done, they knurled the guides. I wish I lived closer. I'd bring my engine work to you. You have a lot of great projects going on!

One the one side of that cross head is pin is turned you change the setup and turn the other half of the shaft. I think it would work, but I can't imagine doing it in a production shop - would have to be slow.

Dave, try a slight angle change of the bit. You will also have to adjust the rotation speed of steel you're machining. You have reached that magical harmonic speed that will magnetize. It's caused by the heat generated by the bit coupled with the ultra-high frequency created by the contact of bit against the steel. I suggest slightly speeding up the rotation and taking less of a bite.

A treat to watch this series of jobs. And at the weld up to match a cast piece, fitted to the steam element a nice answer to the square to round assembly. Who knew my small shop needed a shaper? My South bend is a 1935 model. Where Tom's work came from a 1925. These machines have a long and interesting history, with some great photo's shown on South Bend web records as production across the years. The scraped tolerance of the ways, the early to late apron features and the change gear sets made these units useful but a little demanding to set up. Attachments included a taper device, and both British and US made mill units that clamped to the bed. The bed stamped serial number define year made. Various makers to that design and very often of smaller work piece dimension. I think from the post, both as where Tom is working and my unit, a 9 inch capacity. Most of all where I laugh when comparison to a "Chinese mini". *Durability, construction and tolerance. Tom's workpiece at near 100 years and still productive to that machine. For small shop as hobby or the waves of advance in weldment, grinding tolerance and various alloy...the age of steam gave way to more modern features but at the time (let the observer compute that year range for themselves) were the absolute best of method. In the forests of the west, steam caused a lumber production also unique. Lots of books and photo's to that interest. Dave, what's best to my enjoyment is your patient and knowledgeable comment as real work in an interesting shop, meets unique and everyday. And steam was the powerhouse of delivered force to cast iron and brass and steel real to our near past. Thanks so much for having me along. M.

We use the DCM mill with the table that pivots in the Y and X axis. We get on level to each guide using the guide mandrel and a level that fits on mandrel, then level head to guide. Then we use a core drill and drill out old guide to size, then we press in new cast iron guides and use a reamer to bring them to size. Basically, we keep the old guide in place thats casted as part of the head, the new guide gets pushed into that. Because we level on each guide before any core drilling is done, nothing is out of line of origuonal seat position because of leveling on guide. All in all, because of the DCM mill, we can have a set of v8 head guides installed and sized in under 15 minutes and were on to cutting seats. Seats i dont care for are the big john deere, cat, heads as they get really hard to cut. We do a lot of heads through out the year and the older i get, the less i like the big heavy 170 pound plus heads. Their just a tank to move around anymore.

Hi Dave, love your videos as always. I like the two part casting idea for the crosshead, cheeks and pin cast together, machined, and end cap added after in a re-cast. But also wanted to propose that a wide but narrow shell end mill on a vertical mill could possibly do the job if the crosshead was set between centers and rotated. You'd have to do it separately for both sides, but the mill could reach across the closed gap. Or on a lathe, a driven milling attachment on the cross slide would be similar. The spindle would have to be turned by hand, not powered, and you couldn't go all the way around. You'd have to retract the carriage to clear the crosshead body, but return it after rotating past. Mill, if narrow enough would fit in the gap at the cap end. Not saying that was how it was done, but a possibility, that could also explain the center drilled holes.
@davidhull6359
@davidhull6359 2 жыл бұрын
Hacksaw--you could generate a portion of the pin with a shell mill, but you won't be able to complete the enclosed portion. The unfinished angle would be determined by the height of the crosshead and the diameter of the mill shank. That means it would take handwork to complete the shape. Not really what you want in terms of accuracy and surface finish in the direction of the piston forces. I suppose that you could make up an internal grinding wheel comprised of multiple pieces. (Think of a normal grinding wheel cut across the diameter into segments, then size the hole using adjustments on the frame/housing containing the pieces, and spin it. A pretty specialized tool. Another way to visualize this would be to consider an epicyclic gear set. In the place of the sun gear you have the shaft being ground. In place of the planet gears you have grinding wheels. The outer "ring gear" drives the whole works. I suspect that a steam engine, especially if run as a low rpm/high torque machine would have lesser peak rod forces than an internal combustion engine. That would make the welded crosshead more viable than one might think. Perhaps Dave can enlighten us...?

I think you may be on to some thing there with your first idea. I took a close look at the cross head on the big shop engine and it looks like it's made the same way with center holes on the sides. A quick and dirty way of doing it, but the pin can't be replaced when worn.....Dave

Hi Dave, Another great video! That potato harvester chain conveyor is my definition of a two-person, two-jig job: The master running the torch and bending. The apprentice alternately loading and unloading the jigs. The question is how many of these links do you have to make before you are money ahead having made two jigs? Be well & Best regards, Gottfried

The conveyor was a " labor of love" so to speak, for an Amish neighbor, and guess what, I have another one to make for his friend.....Dave

Cool jig! (ahem...). Looks like you could get a little sunburn while using it... I kinda half expected you to say "Ooo! Hot!" somewhere in the middle of that! :)

Dave I believe they used the losted wax process to create a ceramic core , extremely accurate and no joint line . Example blades for a jet turbine engine no machining because of the hardness of the material . Christopher from Down Under
