    Just picked up a horizontal Mill, what kind is it?

    Re the collets, Maybe a y size double taper? or the old Schaublin e style if so maybe you could use er collets. Also. I think GregSY here on the forum had a set of Schaublin collets a couple of years ago and no way to use them.

    Finishing Babbitt Bearings

    This engine is a 4 cylinder 3.375" stroke. And yes the rod journals are long about 1.5" so are the mains at over 3". Although not much different than a model t. I did the pattern work Dakota Foundry cast the ductile iron crankshafts one should be aware some crankshafts are not easy to pour and...

    fusion 360 or something better?

    I don't use it much but I don't care for the sketch I import from a CAD Link product that is way easier to create a sketch in. It sucks switching between different software but I spend more time fucking around trying to sketch something in fusion than just doing it and importing it. Maybe I just...

    Finishing Babbitt Bearings

    So this engine I'm working on had parsons bronze it was a cheap white metal bearing not as good as a traditional babbit I had one of mine tested contained mostly tin and zinc. Perceval Parsons had an interesting career in metallurgy and engineering so parsons bronze may also have referred to...

    Finishing Babbitt Bearings

    Joe and 99 Thanks for the comments. Joe, my questions weren't for me I know the answers as I've done a few of these I don't know it all by any means I'm always willing to learn. I was being a smartass as I didn't care for tdmigets reply maybe nothing was meant by it but it rubbed me the wrong...

    Finishing Babbitt Bearings

    What do power plant bearings have to do with it? I am not very familiar with them, except that they are very different from die-cast, pre-war car bearings which is what I was referring to not lasting. When you mention that plenty of shops make them last, I am assuming you are referring to...

    Finishing Babbitt Bearings

    Hi tdmidget, I have learned through experience on this type of thicker non non-adjustable babbitt to shoot for near-zero clearance. The max clearance called out is .0012 There is a certain amount of break-in that occurs even a mirror finish line bore job has some peaks and valleys as we all...

    Finishing Babbitt Bearings

    It is ground to size but of course it doesn't need to be. It is also relatively soft. The draw scraping seemed to work well.

    Finishing Babbitt Bearings

    Thanks for all the suggestions. I have also heard of using scotchbrite on bearings it's probably fine but I decided to avoid abrasives. I did something similar to what Joe Michales described above with the parting blade. I had not thought of draw scraping the full length at once I clamped an...

    Finishing Babbitt Bearings

    I Should have been more specific it's tight about ,0002 so it won't go on the shaft you could maybe gently tap it on but being 3.5 long if it hung up or stuck that could end badly. This engine is set up with initial clearance of slight drag after run in most guys end up with about ,0007 -...

    Finishing Babbitt Bearings

    This is another automotive question but should be relevant as many old machines use Babbitt. Is it acceptable to sand or hone a babbitt bearing? I assume NOT as I would be concerned about it doing its job and embedding the grit. Then it could act like a lap on the new crankshaft or, can it be...

    Heat treating terminology

    That's interesting considering Edison and Bell were friends and shared an interest in helping the deaf. Then consider that Edison and Ford were good friends. One would think that Ford should have had the connections to get in. Even in today's world sometimes it's who you know. Do you happen to...

    Heat treating terminology

    Thanks for mentioning ALAM sometimes I forget about all of the political BS that can control who succeeds and fails regardless of the quality or lack thereof of a product. I learned a fair amount about that case at the Henery Ford Museum. All of that corruption in the early days certainly did...

    Heat treating terminology

    Not sure what this has to do with bone-hardening Nevertheless, it's an interesting viewpoint. As someone who has owned early Ford's I currently have a 1919 T along with other early cars. I sure can't see where Ford was at the forefront of tech and steel any more than any other serious car...

    Heat treating terminology

    Very interesting information I never knew about the use of entrails, The bone meal in pack hardening makes sense for the bone-hardened reference.

    Heat treating terminology

    Thank you for the detailed response. We did have to make one gear but it's only engaged in reverse so I just used a piece of 4140 and oil quenched it. It'll be fine for reverse. I wasn't really concerned about recreating the process as much as what it was and how it was done back then I like...

    Heat treating terminology

    I have been working on a pre-war car and they often mention bone-hardened parts. I have heard that term often with regard to color case hardening using bone-charcoal or even just a term used to describe color case hardening usually associated with gunsmithing. However, I'm certain they were not...

    Runn and Start Capacitors for Doerr 5HP 1740 RPM motor... Nidec bought Emerson which had bought Grainger which had bought Doerr everyone says buy new

    Put a 30 uf in and check the draw you'll probably be done. 30 is very common in 5hp 230v 20ish amp compressor motors replaced lots of em. eKretz do you remember what you ended up with? ALso don't worry about the lowest current just get it to the rated fla.

    Is Monel suitable as a thrust wear surface?

    Good point about the copper I don't know why that didn't occur to me. maybe it doesn't matter but that's enough of a reason not to use it. I will just make a small order for something.
