Too many people accept "it's good enough". Thus, when folks strive for perfection, it makes it that much better. I love seeing old equipment properly restored the right way vs. half assed. Well done.
You clearly are not a machinist. Everything is finished to "good enough". There is no such thing as perfection as perfection is an unattainable standard.
@@Katchi_ I think he's using the ah it's good enough in the colloquial sense, which I think when most of us hear that it's not being used to indicate this job is now in tolerance. But rather they're leaving it short maybe even well short of factory or the appropriate tolerance range or specification. Then using the colloquial "it's perfect" to mean it's meeting or exceeding the tolerance and specification for a given item. I'm sure the majority of machinists get the difference and understand colloquialisms.
I said "strive" for perfection vs. doing a half ass job. One thing I know about machinists is many are lacking in people or social skills like you.@@Katchi_
I've found myself watching a lot of your videos and have subbed. One thing I have to say that I like is that you're not afraid to make a long video. I really enjoy these longer ones.
“So it wasn’t crazy.” Really? How about just slightly insane? I’m pulling your leg. You are a master of your craft and do beautiful work. Thank you for sharing, and good health in the New Year.
There was a ton of instructional material in this video comma and you did an excellent job. I will confess. I never thought there could possibly be such nuances to the operation of an arbor press. Well done!
That is some serious next-level work. I appreciate your thorough explanation of why and what you're doing. Using your OCD to its fullest 😂!! Beautiful job! I winced a little when the air gun blew some paint off..
I loved it! I'm a perfectionist too so I feel your pain and even though we make things harder on ourselves than it needs to be when your struggles pay off and everything comes together its an amazing feeling, excellent video and excellent work!! Keep this great content coming, I love your refurbishment/rebuild videos, its nice to see another person go WAY above and beyond striving for perfection! Hope you and your family have a Happy New Year!!
This is a great video. Making the components for the line boring fixture were excellent. These types of repairs take the time to get the fixtures right and work properly. Like you said, having the large amount of hours up front made for a short but quality repair. Great work. Thanks for sharing.
I just love your videos. Just to give a comment on this video. In my mind you solved both issues by taking the play out and taking a little off that gear. Had you addressed just one of the two it may not have worked. Just awesome to see a way to line bore with a mag drill. Great video showing your thought process along the way. That's what keeps me at the edge of my seat.
I wish more RU-vidrs had your OCD! I love your attention to the aesthetic and ergonomic details that others often dismissed as trivial. The end result is well worth the effort. Forty hours of work is nothing compared to the years of looking at an eye sore and struggling with its operation.
Another cracking job. I must admit I wouldn't have been brave enough to drill holes in the casting. I would have made up a bearing support on the angle to bolt to the 4 big threaded holes on the front and worked from there.
Nice fab of a magdrill line boring tool! 2 mil tolerance on a cast iron arbor press is serious over achieving. Perfection young man should always be chased achieving it can be manic. Your repair and refurbishing isa serious success. Kudos to your approach to repair. Now pour a reinforced concrete pad to level and bolt the press down.
Very nice. I wouldnt have been satisfied with these issues either, so good job 😊 And the magdrill line borer is a very nice idea! 😎👍 Greetings from Germany, Chris
I agree with you, that issue would bug me too. It was very interesting and informative to see how you managed to line bore. I know some day I’ll have to tackle a boring job. Great work.
31:46 PERFECT!! one time I had a job (I am also a Certified Millwright) .. drilling and taping, multiple holes in a paper mill .. exactly like this, on cast iron. and our goal ws for every hole we tapped, to go JUST like this! :)
First time I have watched your channel, which I have thoroughly enjoyed. Thank you for taking the time to create interesting content. Most importantly thank you for pronouncing Knipex correctly. That alone earns a subscribe!
At 49:43 there was a glitch in the Matrix! First time watching your videos and I enjoyed it enough to subscribe so I hope you didn't mind me picking on you! ❤
First off... DAMN! What kind of freezer you running! Back in the 80's I was being taught how to line bore. The set up was very much like yours. The only real difference was that where you installed a spacer bar we had a double U-joint in line to allow the magdrill some offset. Sometimes you can't mount it totally flat and square to the bar. Good looking job!
Excellent video and explanation on every step I am surprised you didn't step the cover and shim the rack and loose the set screws but what a nice size press plus the compound leverage I have a dake compound but not large enough, thanks again for sharing hope you have a great new year ed
When you honed that oil lite bushing, it could have been possible to “impregnate “ honing grit into the bearing. Making it more of a “self lapping” feature now. But honestly i dont think an arbor press would see that much rotation for any amount of discernible wear. Just a thought. I wouldnt do that on a bushing that sees alot of rotation. Great video, great content.
The construction screws you used is a solid idea, we do that in field machining alot for line boring or portable milling/lathe equipment mounting. Though for future reference, you can weld your bearing blocks to most grey cast iron if you absolutely cannot add additional holes. E7018 rod or 309L will get enough adhesion for the bearing block leveling screws or you can braze them on if you are setup to do so. Wouldn't advise doing it on ductile iron tho.
Excellent job! Especially as it's your first time line boring. The three bearing block idea was definitely the way to go. I could not see you getting the concentricity using a cone to line up the hole to be bored. You reckoned that the drop in the worn hole was around 40 thou. Was that 40 thou of ovality in just the vertical thrust ie downward side, or was the hole oversize in the horizontal axis as well? I ask this as you didn't show you using telescoping gauges to measure the bore. A very interesting video. Happy new year to you from England!
Hmm not sure I think they are brass at least when I filed them down they looked the same color but who knows maybe it caught some metal dust or something anyways I added a strip of brass behind the screw to distribute the load. Sorry didn’t show that.
Nice job, some thoughts on your proces. I have rebuild or modified existing machinery a lot and learned that the more cautious or accurate you perform the better the result. I know you're aiming the same way. However; why didn't you check concentricity on bearing fixtures you made when you flipped them? I know a 6 jaw chuck should be pretty good at this but a check with a dial indicator and a light tap on the part would enhance your self confidence along the road (I made this like so en so and it's solid as a rock instead of maybe I had to check the runout before cutting the backside because it's not working as I had in mind) You stepped into this loophole before as you explained in the beginning and added a struggle in the end too. A press fit on a a thin bushing changes the inner diameter also. This can be predicted quite well with accurate measurements before mounting. The amount of press fit on the outside is translated quite linear to the bore on the inside I experienced. I probably sound arrogant but's that not my intention. I travelled exactly the same road you took and learned of it. Checking all play on bearing surfaces (and indeed wondering how the axial grooves originated) and measuring everything moving in relation to each other. You ended with a perfect job but took some shortcuts which added more work in the end and could, thankfully not, destroy the desired results. In process building as accurate you can adds just a tiny amount of time but it's a) really rewarding to know that an eventual fault or bummer cannot be addressed to the parts you modified or remade and b) saves you a lot of time just as you experienced in modifying this pink (?) arbor press. Just my two cents. You get there. I promise. Just take notes ;-) All the best, Job
@@VanoverMachineAndRepair Any case you’re all set up for line boring missions now. Good work love the content! And I hope the new year brings good fortune!
Hydmech s-20 manual great saw would buy again 30 years old works flawless. One of the only machines I brought into my shop and didn’t work on just put it straight to work
