well after 30 years I finally finished my Bill Harris steam roller. It was a fun project. Now that I'm retired maybe the next project won't take so long.

almost done, all that is left is the water tank and coal box.

More progress on the steam roller, all that is left is the coal box and water tank.

So I have been working on this Steam Roller on and off since about the early 90's. I have the rolling chase all assembled and painted. I have all the engine components made and had it parchally assembled then my basement got damp and the engine got rusty. I fixed the basement walls installed...

November, 2018 I just started to work on the steam roller again after a very long break. I had to take the engine apart it got rusty. I have most of it back together again and turning smoothly. lets see how ;long I stay on it this time. Dave

This is the lathe I baught about 15 years ago. It's gone up in price since I baught mine. I've had good luck with it so far I've done everything from small parts for Model Engeneering projects to big diameter parts with great accuracy. Dave...

Maybe this thread will give me insperation to finish mine, I've been working on this for the last ten plus years. I have all the engine components done, all I have to do is assemble and mount then make the water tank and coal box. Oh I almost forgot the water pump too. Dave

And then the alarm clock went off...time to go to work...Doh !!! Only kidding. Great story and sounds like a great bunch of people. Dave

I guess I would have to say North Safety brand seeing as that I work for them as a prototype specialest. Northsafety Now part of Honeywell

Bob, Looking at your parts again it looks like to me that the end mill might be a little dull, too long or feed too fast. Small dia. carbide end mills are affordable these days you might want to try roughing out with a high speed then finish with a carbide with higher spindle speed. Just a...

Was the end mill an import? If it was it wouldn't suprise me becouse I've ran into the same thing on my CNC Machine. I alwayse check the diameter first now and plug that number into the tool diameter offset with good results. Also I try to use the shortest flute length I can get away with to...

This is the one That I have put on my mill http://grizzly.com/products/Quick-Quill-Stop/G7316 Dave

Here is the Huff & Puff one by Philip Duclos done in SolidWorks

You are correct, but if you are going to use an end mill with a flat on it in a collet don't hold on the flat always make sure you are clamping on a part of the end mill that is completely round slide the end mill up in the collet as close the the flutes as possable and you are good to go. Dave

I have the sherline 4 jaw chuck mounted on a 5-c collet adaptor and I like it, the jaws are small enough to hold small stuff. The jaws on the little machine shop 4 jaw chuck look a little to big (just my opinion) to hold smaller stuff. good luck in your decision. Dave
