Good to see you are using accurate measurements there mate, but I think you need a bigger one 🤣👍🍌

[@ShainAndrews]

Hey... it's that guy! LOL.

[@ChrisMaj]

I know you metric guys have a hard time with inches, so I thought that might help. If you ever have a bigger one in your store, let me know, I'll be the first one to get it 😉

Bananas 🍌 r used Kurtis is somewhere not far behind 2 give his Input ! 😁😁 🇨🇦

[@thepubliceye]

First, his tool post reminded me of CEE then came the scale.

[@tomtd]

As a young design engineer in the rubber and plastic industry I designed rubber mills for Francis Shaw & Joseph Robinson. This was everyday stuff back then 800hp gear sets, huge bronze water cooled bearings on the journals 90” wide 24” dia rolls some micro finished other’s helical grooved. Loved every minute before I went or king for Loctite. Then of course we in the U.K. began our great decline and deindustrialisation, now there’s no trace of these once colossal companies and all that skill base is almost all dead and buried. Makes me so sad that so few today have work they can take pride in, beats the work in a call centre by some margin and what’s the point of burger flipping by comparison. Nothing like the smell of cutting oil.

A banana ruler, did Kurtis send you one, they are very accurate, good to see you using it for layout work. 8mm grooving tool working well too!

[@ChrisMaj]

I bought it from their store, but they did send me some extra goodies.

[@mrz80]

I still say I want a micrometer that reads out in thousandths of a banana :D

[@tomtd]

Don’t mock the inch, fractions are absolutes, base 12 is a pretty good mathematical system, ask a mathematician. More difficult no doubt than base 10. Engineering wise the very first standards were set by Joseph Whitworth in 1841 and he measured to one millionth of “a banana” and designed the most efficient threads in terms of clamp to applied torque, to that date. His measuring device could show the expansion of a metal bar by the heat from a finger, 140 plus years before everyday accuracy of “a thou”. True engineering genius. Remember too that with base 12 and fractions there’s no rounding errors commonplace in metric, the blight of pcb layouts.

That was one of the most stressful jobs in a long time. I don't know if it was the size or the price tag for the forgings ($70,000 for two pieces)

[@richardeholder]

Yes. Both.

Nice work man. Those forgings are mint. What baffles me is the lack of scaling on the diameter tolerances.

Measure twice cut once, in your case it's magnified! Nice job, from a non- machinist!!

[@shawnhuk]

@@steelwheelsminnesota the bars have clearly been rough turned somewhere else.

[@sicstar]

The combination of "oh sh*t thats expensive" and "oh sh*t if i break it it gonna take 3 months to get spare material and we never hear from the customers again" also maybe "oh sh*t if i drop that thing we gonna need a new machine or workshop floor/crane" is quite gnarly yes. Only had 2,75 tons on the machine so far but that thing was stainless so price wise some muscles were clenching indeed :| Excellent job as usual there man!

[@stephenvindich7532]

Got a fix8 on order right now... when I saw the gear on floor I thought I was looking at my old workplace :)

Loved seeing the banana rule from CEE Australia. Been watching you for a long time and love what you do and yes I'm from Tasmania Australia.

[@ChrisMaj]

Yeah, I've been watching Kurtis probably from the beginning, so I thought I'll use their banana ruler in my video. They gave me a few pointers with all that KZbin stuff, but I just don't have the time to spend on all the editing.

Great workdone💯

[@oxtoolco]

I'm curios the reason why you finished the center section diameter after the milling work? And on a different machine. Was there something special about that center section that I missed? Was it because the Hankook didn't have enough X travel to reach that section? Love your work. You are certainly making the most out of the Fanuc control. No CAM required! All the best, Tom

[@ChrisMaj]

Yeah, the Hankook didn't have enough swing.

[@oxtoolco]

@@ChrisMaj Bummer. You had to use the old clunker to finish that nice arbor shaft. That old girl looks like she was rode hard and put away wet. Blue chips and chatter for days. Cheers, Tom

Hi Chris happy Sunday. Thank you for this new video of machining a huge axis of five tons probably intended for the navy or heavy industry? I saw that you put the banana ruler of Kurtis the Australian from the EEC on your piece, it's funny because I follow his videos like yours on You Tube, it's no coincidence. See you soon to see your great videos Chris thank you.

[@andrewtetley3883]

Wow that’s a big lump of steel, Chris am I reading the colour of the steel correctly?? Has it been case hardened? Or is that just the colour of the steel as it came to you? Also a shout out to Kurtis of CEE for sending you a banana ruler love it 😊😊 As always Chris just wonderful work that you do, I never got to play at stuff that big.

[@4418CARLOU]

It wouldn't have been case hardened.

[@ChrisMaj]

I think the forging company did some sort of heat treatment after roughing. Yeah, I bought one for CEE store just for fun. They did send me a few other things.

[@currentbatches6205]

1:52 - Curious regarding the centers' ability to hold that weight. 1:57 - Is that weight conditioned upon some tail-stock spindle extension? 4:17 - Curtis will be amused. 12:06 - Starting at 5" and ending at 11-1/4", there appears to be a taper with the base dim of 20.424", but I don't see a major dim. Illusion? 14:39 - Didn't think the 'floor' of that groove was going to stay in that condition. 16:26 - Do you keep your mics under controlled temps?

[@ChrisMaj]

It says in the book 11000lbs max, I'm sure there's some room to spare. Kurtis said that I'm finally using some real measuring tools. 5" that's a center of the bearing 11 1/4" center of a radius. Mics are on the shop most of the time.

@@ChrisMaj THX for the reply. "It says in the book 11000lbs max, I'm sure there's some room to spare" - Probably a good guess; their legal department doesn't want to argue over a couple of kilos. "Kurtis said that I'm finally using some real measuring tools." - Pretty sure you speak both Imperial and Metric, as does Kurtis, but it's a point of amusement for him as it is, I'm sure, with you and me. "5" that's a center of the bearing 11 1/4" center of a radius." - will have to take another look; rare to miss a feature datum on a drawing but it has happened. Would you please give link to a drawing/time where that is clear? "Mics are on the shop most of the time." - Hope you understand this is NOT a criticism of you or your techniques, but if a customer spec'd +/- .001 on >20", I'd want to know the measuring specs or ask for the use of the customer's mic. Bit of background: Grew up where kids learned how to run machine tools by osmosis; absorbed from the air. By age 14 or so, was using a 20"X 60" (memory, but close) flat-belt-driven lathe and learning how to deal with worn out head stock babbit bearings,. And learning to use a KT horizontal mill. At 18, a major machine tool mfgr gave me the responsibility to do the final inspection and sign offs on machines worth (at that time) ~$250,000. I Had no idea what that responsibility meant at the time, but not a one of my machines ever got questioned by any customer; they WERE within spec. No brag; fact.

[@victimovtalent6036]

arbor for bench drill?

[@michaelarias7324]

How do you go about running such heavy parts? Seems kind of terrifying, what would you set your pressure and is there any tips you can give to roughing heavy materials? Currently at my shop we have a guy that will retire at the end of the year and he roughs huge heavy shafts. I want to learn how to deal with such big parts but they seem intimidating any tips?

[@ChrisMaj]

The chuck and the tailstock are all manual, so kind of go by feel. Keep your jaws tight, or the piece might spin on you when taking big cuts. Don't drop it on your lathe.

[@franz_k6000]
