If it is anything like the receiving dock where I use to work, no one saw it happen, no one knows who did it, as matter of fact are we even sure the lathe was ever here?

Dave, First, that is some very nice machine work you are doing on that engine. Second, a HUGE THANKS. You helped me greatly from seeing those images. I think I have a new plan of attack. The image below is what I have in mind...... I clamp the casting on it's side and use the upper edge (red...

Being stubborn and dense, I decided it was time to take on an engine from castings. I bought the PM Research #5 Coke bottle engine set, and now I am lost........ I figure the best place to start is fly cutting the frame base to be flat and square. To do this I have a 9x36 mill and a Southbend...

Wow. Who ever came up with that idea for advertising deserves a raise.

I had a member wanting to see the EZ Engine that I had built. The images in the build thread have been deleted so I am reposting some pics of the engine here. Sadly the little guy has been sitting on the back of the work bench neglected, I do have plans to polish it up....some day.

I had to learn the metric system in college, and you are absolutely correct.

I came across a unique tool yesterday at the local pawn shop, and to help pay back the forum members for all their help I thought it would be nice to loan the tool out to who ever may need it. It is a quality Japanese made wood auger in 4/16" diameter. You know, when a 1/4" hole is just a bit...

Years ago (1990) I use to be a security guard at a company that built gas burners for steam boilers. They had what they called a testing room which was a large room full of various sizes and models of boilers. They used these boilers to test the various burner designs. Since there was always at...

My Grandpa started out on the AT&SF as a engine tender. His job was to sit in the cab of the steam locomotive and maintain the boiler so the locomotive would have a head of steam for when it was needed. The railroad was paying for one man to sit in each idle locomotive, plus the fuel being burnt...

My lab where I torture machine tools and turn useful metal into chips, is a 11'x15' building. The building came from an old refinery and was built for industrial use, I am probably the only home machinist with explosion proof electrical system in my shop. It has a heavy metal outer skin, 8" of...

When I was working at a factory there were a couple times I got to go home to get to work. I was running a CNC punch press that decided to break down during our busiest time. After waiting a week the high dollar part shows up, a flanged ring with a few slots milled in the flange. Of course the...

Very interesting post. Learned a few new things... :bow: 1. horological suppliers.... had to Google that one, learned what that was. (if anyone else doesn't know I ain't telling) 2. Wax chucks.... I had never heard of this and find it so useful yet so cheap and simple. I could have saved a lot...

Amazing. Great build. :bow:

My Dad always told us there are two types of plants, weeds and trees. A tree is anything to big to mow over. ;D

I wish I could tell you the answer, but my knowledge of extruding metal is very limited. Hopefuly someone with more smarts will chime in, like Bogstandard.

My mostly uneducated guess is that the aluminum was extruded. The markings show the direction the metal was extruded.

Thanks for the link. Brought back some old memories.... My Grandpa was a Army Air Corp mechanic during WW2, and was assigned to work on the old Radial engines. When I was about 12 or so I asked him how did all the connecting rods fit on the crank without hitting each other.... Grandpa did his...

You might want to check the run out on your set up. The smaller the bit size the more sensitive it becomes to run out. Somewhere in my buying/trading of shop treasures I ended up with a small Jacobs brand drill chuck mounted on a 0 morse taper arbor. It was meant for a Sherline or similar...

That is my thoughts as well. Use a .75 dia wheel with maybe just a bit extra thickness. I think the smaller diameter wheel would still look in porportion with the engine.

A few nights back me and the head of engineering, my bassett hound, were sitting on the porch. I was smoking a fine cigar and had polished off a bottle of Bushmills when my bassett said, "Hey! Why don't you build an engine in that empty whiskey bottle?" I of course said it would be to difficult...
