Hey Keith. Love your work, thanks for posting it. Suggestion if I may. Restrain that key before you spin the shaft up, especially if you are going to touch it with the cutting tool. A worm drive hose clamp will do fine. I know it is in there tight but if it does come out it will find a way to do you a mischief for sure. Cheers from Down Under.
I'm a retired maintenance technician for a manufacturing plant. Since profit was not directly my focus, I put centers in every shaft, if possible. It gives a puller a place to center on.
I’m very impressed with how serious you are taking this transition into full time content creation. Consistently seeing new content being posted from you really brings a smile to many of us. Since it is your full time job now I’ll hop on over to Patreon to help show my support.
This monster press is gonna be better than new. Already is. Amazing to see, and you can tell Mr Rucker is totally lovin' this project. I can fully understand his enthusiasm. It's awesome just to watch the pieces we see here.
I'm not a machinist, other than as a late-in-life hobbyist. I'm a retired childcare worker, who worked with kids from the time I was one. I remember reading books by Richard Scarry to some of the first kids I babysat, three young boys. They especially loved 'Cars and Trucks and Things That Go'. I didn't know it at the time, but the book had just come out that year, in 1974. I was also a later-in-life dad; my son was born just before I turned 41. He also loved 'Cars and Trucks and Things That Go', as well as any other books about machines; the bigger, the better. The thing is, I loved these books, too. There's a boy in every man, I think. Or maybe a bit of man in every boy? I get such a kick out of watching these videos, especially the series with big old machines used to restore big old machines. The more machines, and the bigger, the better! Thanks for taking us along, Keith!
“It will be just fine.” and “No big deal.”….I love hearing these statements every…or almost every video. I wish Keith was my high school shop teacher in the 80s. I would have tried harder. Love the videos and the projects.

The key at 27:50....is that not just in there with a friction fit? I would have been scared to spin it that way and either taken it out, or put a set of hose clamps on to try and retain it from flying loose. Hopefully later in the video it stays in and does not cause issues.
Fun fact for math geeks - the small gears have 13 teeth, which is a prime number. This makes the small teeth meshing with a new tooth on the big gear every revolution. This evens out the wear on the teeth.
@ I guess I should have been more specific. 13 is prime and is not a factor of 77. Therefore, every tooth on the small gear meshes with every tooth on the large gear before repeating, leading to an even wear pattern on all teeth for both gears. If the large gear had 78 teeth, then any given tooth on the large gear would always mesh with the same tooth on the small gear leading to uneven wear. Setting this up is simplified if one or both gears have a prime number of teeth.
thanks for the video . just talked to my cousin in Montana he had his pine trees thinned . then the wind came up and blew down a bunch more trees. the loggers were out of the area so he is cleaning it up.
Keith, i wish you had removed the key from the second shaft you turned it in the lathe. Or at the least placed a strong hose clamp onto it. Take care, be safe, and carry on..
I was thinking if just the rotation of the shaft didn't send it flying, the slight contact with the cutter would bang/vibrate it loose enough for that to happen. Angels were watching.
Video Recommendation! Next time you swing from the press handle do a super long loud Tarzan yell. It will increase the pressing power by 35%. Thats your life hack of the day.
WOW! This has become a major project. Certainly there are a limited number of facilities in the US that can tackle a project of this complexity. While this methodology was standard at the turn of the century it is to day a lost art. Very enjoyable to see the process thru. Hopefully at the conclusion we can see this mill in operation.
Thanks again for tripling your workload just so I can sit here sipping coffee while you work. Seriously, its quality work all around. I also see an upward curve on the videography. Ain't learning fun?
Make me think of "The Chain Rule" when you were talking about the gearing. I hadn't thought about that for a while. I am waiting to see how the shafts are positioned for the pour that keeps the pinions properly meshed with the ring gears.
Baby steps.... I told one of the old men in the shop that one time and he said "Babys take baby steps but remember this, they fall on their baby butts while taking baby steps until they get it right." The moral is ??????, or it is, little screw-ups are learning steps to the finished product. Over the 72 years of my working life, I am still taking baby steps on new projects as technology is always about two steps ahead.
That is a monster mill ! For a single person shop that’s a lot of heavy rigging to get everything done to your standards! Well done I am enjoying following along ! Thank you for all the efforts you expend to video and edit this for us!
I put a ¼ HP blower motor on my Happy Valley cider press grinder. Optimum speed of the grinder is about 60 RPM (determined empirically). I originally used pulleys and a jack shaft. I used a spreadsheet to calculate pulley sizes using available pulley sizes. It worked great, but seemed kinda dangerous. I'm in the process of replacing the belts with a ½ HP Boston Gear 30:1 worm gear that I bought on eBay. That reduces the 1725 RPM motor to 57.5 RPM. There are eight blades on the grinder, so a blade cuts into the apples every 125 milliseconds. Faster, and they bounce around.
If the bar you used to press the axle out was not faced (not flat) on the end(s) it will cause the piece to bind in the bore when the piece being pressed gets close to the end and almost out. I've had that binding problem before but our press was a 150 ton unit so the binding showed up as an increase in the hydraulic pressure.
So based on my math and assuming the engine pulleys are a 4:1 ratio, this thing would have roughly a 76:1 gear reduction. If the cane mill steam engine operates at 55-60 rpm, which was common for cane mills of the day to control crushing rate, the final drum will rotate at .75rpm. If the steam engine has 330nm of torque, then the final output would be ~25,000 nm at the drum. Does this sound right?
That hanging on the arborpress shaft is a no-no .. did that on a sheet metal shear once .. smacked my head so its a miracle im alive today ... heavy stuff and if it lets go the pipe will smack you in the head .. and it hurts =)
It appears from the camera angle that the spacer you put on the shaft when on the arbor press was not free of the gear. You had no chance of pressing it out when you were pressing on the gear.
Hi Keith...love your channel and thank you for sharing! Quick question from a non-macinist. Since you had to do all that turning would it been just as easy to replace those shafts and recut the keyways or is there a lot more to doing that vs what you did?
Luckily the key way did not fly out!! Should add a bronze thrust washer to each side of the drum shaft and idler gears to prevent the drum and gears from rubbing into the bearing side surface?
@@Frank-Thoresen I think you may be right, but I think I'm right about the pressure being applied to the gear and not the shaft when he was using the arbor press - or it could be an optical illusion.
@@stumccabe The end of the shaft was sitting a bit proud from the gear. There would have been a little bit of movement if the arbor press could handle it. The spacer was right on the edge but wouldn't have been pushing on the gear.
Interesting ratios. I note that each pair of meshing gears has no prime factors in common. This maximizes the time between any given two meshing teeth on the gears coming in to contact, I guess so that there is a minimal chance of a damaged tooth causing a wear issue on the gear it is meshing with. It certainly isn't because setting up a 77-tooth pattern is easy on the mathematics!
Morning Keith, As always I enjoy your repair videos and appreciate very much your time, effort and knowledge you put into sharing this work with all of us. I would feel guilty if I didn't mentioned as others may have already seen and mentioned, (Keys left in keyways during turning) we all know, and you know the danger of centrifugal force can create with parts coming loose. The higher the speed and heavier the weight the more dangerous of becoming a projectile. Watching you turning that shaft area and then clipping the end of the key with the cutter made me cringe even more. Obviously it didn't come loose because we were watching the video, but we all know we may also have been reading about you being very badly hurt or being killed from a very bad accident. Heck, hose clamps, even several wraps of good tape around that key would make sure it would never come loose. Thankfully it stayed in place. None of us want you to become a statistic. We love your work, your videos and your help too much to see you fail in this way. This is just a warm safe hint from one of many of your faithful watchers wishing you well and not a criticism of you. We all are human. Thanks for sharing.
Great video! What ever happened to the Victor safe? I was catching up on your old videos (9 years) and this series really fascinated me. I was looking forward to the dial and lock the whole time, but the latest video I can find is the pinstriping. Did the safe ever get finished?
23:10 Mr. Rucker with all respect here, a shorter bushing that is closer to pushing out that main shaft should have been tried out. You are only increasing the chances of that bushing launching out like a dangerous projectile. Safety!
One reason for having a shaft with a 2 and 11/16" shaft is that ball bearings are usually metric sizes and less metal is needed to be removed to get to a metric dimension such as 65mm or 70mm.
Keith, aren't you concerned that the open keyways are going to chew up the Babbitt bearings as the shaft spins? May not have been a bad idea to fill the excess part of the slot with weld and turn it down, since you were turning the shaft on the lathe anyway to clean the pitting.
Would it have helped anything to cut off the oversized keys and avoid the collision with the bearings? It would be more work and you would have to weld out the unfilled keyway. Probably more effort than the result would justify.
Having recently discovered this channel I occasionally wonder how any or all of the traditional machines have survived our gov’t. People at OSHA must lay awake all night dreaming about regulating and guarding them.
I would guess that the reason that shaft sizes tended to be on the sixteenth is that back in the day the shafting wasn't that precise so it was common to design bearings a sixteenth under common nominals so they could precision turn all their shafts in house.
Since you knocked that gear off, it sure seemed like a good opportunity to weld up that over-cut keyway. Especially given that it will interfere with the babbit- it sure made me curious why you didn't decide to weld it up.
That was my thought too. I think the key way would touch the babbitt bearing and cause it to wear out faster, same thing he said about the pittings on the shaft.
@@Frank-Thoresen The keyway only extends a short distance into the babbit. Once it has worn a few thousandths clearance it won't continue to wear on the babbit. The pitting on the shaft was over a much larger area. In a perfect world, it would be nice to have the keyway filled in, but if it were a perfect world it wouldn't have babbit bearings
Were you comfortable with the keyway interacting with the Babbitt? I see you didn't bother welding up the keyway and turning back to size. That's a big mill! Cheers.
Why not just turn the keys with the shafts, then fill the excess keyways with damming material prior to pour? That would save the hassle of making a pouring mandrel.
I really love your videos and watch all of them. I have a question. Sense you had to turn the shafts anyway, Why didn't you weld in the key way slot ends?
If the keyway slots will interfere with the pouring, why do you think they won't have a reaming affect on the poured bearings after pouring? Since you are making a mandrel anyway, why not just make a new shaft and slot it right? Just thinking.
Hey Keith. Love your work, thanks for posting it. Suggestion if I may. Restrain that key before you spin the shaft up, especially if you are going to touch it with the cutting tool. A worm drive hose clamp will do fine. I know it is in there tight but if it does come out it will find a way to do you a mischief for sure.

At 23:47 it looks like you were pressing on the gear, not on the shaft - that's why it wouldn't budge!

Great philosophy! The kids I teach get so overwhelmed and it keep asking them, How do you eat an elephant, I bite at a time.
Maybe a 5 gallon pail to catch the shaft?
Would it have helped anything to cut off the oversized keys and avoid the collision with the bearings? It would be more work and you would have to weld out the unfilled keyway. Probably more effort than the result would justify.

The pitting on the shaft was over a much larger area. In a perfect world, it would be nice to have the keyway filled in, but if it were a perfect world it wouldn't have babbit bearings
Because he is an even worse welder than he is a machinist, if that's possible!
Were you comfortable with the keyway interacting with the Babbitt? I see you didn't bother welding up the keyway and turning back to size. That's a big mill! Cheers.
How were the keys captured when they were spinning on the lathe? Seems risky if there was only a friction fit holding them in.
The Engine restoration project. Is it on RUclips?would love to watch that project. I have a 1913 Stover K.
I'm not a machinist, but I am an engineer and though that key stayed in place, I think you were lucky it did so
Why not just turn the keys with the shafts, then fill the excess keyways with damming material prior to pour? That would save the hassle of making a pouring mandrel.
I really love your videos and watch all of them. I have a question. Sense you had to turn the shafts anyway, Why didn't you weld in the key way slot ends?
Welding would cause tension in the shaft and make it pull and no longer be straight
Isn't it a bit risky, spinning that shaft with the key still in it?
What's preventing the key from flying out?

Nice 😎😎😎👍👍👍
If the keyway slots will interfere with the pouring, why do you think they won't have a reaming affect on the poured bearings after pouring? Since you are making a mandrel anyway, why not just make a new shaft and slot it right? Just thinking.
...Doesn't that big arbor press have a back-gear on it?
Nice
