For those asking about the horizontal alignment, I'm sure he'll mention that when the time comes. First you do one plane, then you do the next. Probably reference the bolt holes, is my guess. .I love these restoration videos. Lots of interesting problems, and interesting solutions. The end result is a great old tool brought back to life and good as new, or better. Thanks, Keith, for sharing your passion with us all.

@robinghewitt 2 года назад

Another fun video, keep up the good work, very entertaining. If your drill is trying to start off-center on the lathe there is a wicked trick. You bring the toolpost up against the drill near the end and bend it. The drill tip can no longer wobble, it cuts oversize but it cuts concentric which straightens everything out.

@passenger6735 2 года назад

I can foresee a couple of problems here Keith unless there is a method of aligning both shafts to each other as well as to the machine. 1. I think I would have turned an accurate outside diameter whilst the jigs were in the lathe so when you referenced off they will be identical on both fixtures. You may be lucky but it's worth checking before the pour. 2. The axle will be good in the vertical sense but there is no method for lateral adjustment. It needs to track true in two planes. 3. There is a lot of mass to heat up before the pour and you've already painted it. Great project all the same. Thanks for taking your time to do the videos.

@WhatAboutTheBee 2 года назад

I had the same thought. Nothing stopping Keith from doing just that. But after consideration, its probably a waste of time. The saw is very unlikely to see enough usage to ever develop enough wear to justify repouring the babbit. Reason 1: there are no guards, anywhere, on that saw. Given that a bandsaw resaw will use a very wide blade, that is a lot of scary sharp metal slinging around. Likely that Jimmy turns it on, films a video and then, with all due respect to Mr. Diresta, changes his underwear. So either blade guards are added or the saw gathers dust. Reason 2: Large modern bandsaws move the blade, not the block of wood. Moving the block of wood large enough to justify the use of this machine is a challenge, in and of itself. I can see using the saw for demonstration, but not for production. If it is for production, the moving carriage saw is far superior. Reason 3: Babbit doesn't wear out rapidly. If it did, the old timers would have used something else. Wikipedia states that in old automotive applications, babbit would last ~50K miles. That is > 1000 hours of driving. Jimmy isn't going to run it 1000 hours in his lifetime.

@kejay74 2 года назад

Hi Keith! As with ANY Sunday morning quarter-backing....I believe I would have approached this a little differently. I would have left the two pieces as one until the "shelf" was machined out of the middle with the vertical mill. Then would have split them apart. Possibly with a slitting saw in the vertical mill as well. My $.02 worth. Ken

@1903A3shooter 2 года назад

@ProfessorMAG 2 года назад

Keith, how are you going to maintain concentricity with the original babbitt bore? These supports will maintain an accurate Y plane but not in the Z axis rotational. Keep in mind the two axles need to be parallel to each other and perpendicular to the frame in both the X and Y axis. These bushings could have done both.

@kucukalika 2 года назад

Hey Keith! Nice project going on, thanks for all that. Would you consider measuring the located shaft with respect to the machined surfaces you have before pouring the babbitts? Since you didn't machine the outer surfaces of the rings, the zeros you took for second operation (milling) could result in slightly different heights for the inset of the bushings... I hope the centerline comes out great. Thank you very much for all these different series!

@pmhandymand2012 2 года назад

Would be nice to see how much the rough outer edge change the centerline!

@daleburrell6273 2 года назад

@josephkrug8579 2 года назад

And you can send the fixture blocks along with the saw in case they every do need to re-pour the bottom bearings, so that is a win win. Always love these videos...though I did have to wonder what havoc the cat was wandering along the bench edge to create at one point. :) ie maybe a 'what needs to be on the floor vs the bench' or who knows what. :)

@jbrown2553 2 года назад

As for final alignment of the shaft in the horizontal plane as well as the plane through the X-axis, I'm sure he already has a solution that we will see in the next segment. I think he maybe misspoke on the RPM he ran during the boring operation ?? He said "720 RPM" which would give around 1260 SFPM. Unless that is fine for a carbide insert. But I am just a HSS hobby machinist. (He was using around 80-90 SFPM with the HSS drills).

@TheFreshmanWIT 2 года назад

So not sure you mentioned it, but how are you going to keep it straight in the "other" axis? This makes sure it isn't canted up/down, but do you have something to keep it from getting canted left-right? I would imagine a twist there would cause problems as well, right?

@millomweb 2 года назад

Keith - I'm pretty sure that any cutter speed tables would be based on industrial cutting and hence with the use of flood coolant. Taking the same cut without coolant is therefore a recipe for shortening tool life (between sharpening.)

@lwilton 2 года назад

Very nice! I'm interested to see what you do to make sure you have to shaft exactly perpendicular to the bearing channel so you don't have twist between the top and bottom wheels. It looks to me that the current setup can let you move either end into or out of the throat by about 0.100".

@paulcopeland9035 2 года назад

@MyLilMule 2 года назад

Really enjoying watching this project move forward. I am curious, what are you going to do to make sure that that shaft is not askew? Seems this will solve the problem of keeping if level with the machined surfaces, but what about making sure the shaft is perpendicular to the plane the wheels will eventually be in? The upper shaft would also need to be in that same plane.

@jservice6594 2 года назад

My concern also. While the table probably have some adjustment, the upper shaft does not. It is most important that the axis of the upper and lower shafts be exactly parallel in all 3 dimensions, otherwise the blade will wander off. By comparison, the table being off by a smidge really doesn't matter.

@johnfriend240 2 года назад

Two concerns: Machined surface is painted with what I believe you said was 2 part epoxy paint. That can be pretty thick (0.010-0.030") and not necessarily evenly distributed. Second, what controls the left to right alignment?

@markbernier8434 2 года назад

I second that thought and also wondered how he plans to keep the two fixtures tight against the machine. Perhaps F clamps?

@lwilton 2 года назад

Assuming the paint is the same thickness on both ends (yea, I know, "assuming" :-) then I don't think it matters a whit if the axis of the shaft is exactly on the machined parting line of the bearing halves. It will end up moving with use anyway. It just needs to be about parallel.

You really need side shields on your glasses. Granted I have one of those mini-combo lathes/mill thyngies, and that may present hazzards you won't run into with real machining tools. But I just had a chip form the mill bounce off the upright and hit me in the left eye. Umm...No I wasn't waring shide shields, but fortunatly I was only cut in the cornor of the socket, and not blinded. I do have side shields now but not terrified into using a full face shield, unless I think there is a chance of an explosion. I enjoy your show and presentation, we'd both hate to lose that because of a errant shard of steel.

@robertginther9248 2 года назад

My thought also. Would put a strap clamp to push down on the fixtures at each end as I saw the collar "wiggle" when you set the shaft in, which would improve the vertical alignment.
