That was the best boring video I’ve seen in a long time.
The Mennonites have taken over sorghum production here in Kentucky, and are still raising it pretty much the way it was done in the thirties and forties, and probably earlier. They still use a cane mill to crush the cane, sometimes with a horse, and sometimes hooked to a pto, and they still boil it down using the boiler off an old steam engine to produce the heat for the boiling.
Thanks Keith. It's nice to see mistakes and honest of you to post them.
As one who has "raised cane" cross the South, that boo-boo is no problem. Chamfer it as little as possible to smooth it out, and put it on the bottom.
When I was at Boeing I made a lot of parts from UHMW and other plastics and I found as you did you must keep a keen edge on the cutting tool. We also made a lot of wear parts from phenolic. That is some nasty stuff and will kill a cutting edge quick. We all make mistakes from time to time. I once leaned over a Cincinnatti mill to turn my coolant off and hit the Y axis lever so it happens to the best of us. If I remember right don't they grind cane at the museum? Can't beat some good old cane syrup on a stack of pancakes...........
What a great video. I got totally inspired on how to use my horisontal mill for drilling/boring. Thanks Keith!
Thank you Keith! I agree with many comments that it would be interesting to see a video of the cane mill in action
Yea, I want to see some cane grinding. That would be a fun vid to watch.
Video on mill in operation would be great.
Watching a sugar mill would be...Sweet (sorry)
At 70 years old and a retired bricklayer, I have seen Bozo many times and in many ways. My philosophy? Fix it! Enjoyed this video and hope you make it to the cane deal and take some video. Thanks Keith, Greg.
Charles Compton. my pal and I both did masonry. When out on our bikes we stop and admire old brickwork. It amazes me that a lot of buildings have high quality work but they were not particular about the bond or throwing a clip in. There are a lot of sand mold bricks in NW Ohio!
Yep Mr. Hefflinger, there a some of the old brick buildings down in Portsmouth, OH also. Most of them went through the 1937 flood which pretty much affected all the area down here. I've laid quite a few "sand mold brick on houses but not many commercially. I think the new Sand mold brick are not really sand mold but may come prom a pug mill with an extra press of some sort. We'll have to visit Belden Brick over in Eastern part of our state. Greg
My wife and I have a second home in Thailand. A common sight at local outdoor markets, is a hand cranked cane crusher/juicer. They resemble a clothes wringer somewhat. I can't resist buying some fresh juice every time I see one. Deelicious !!
yes they look just like a sock mangle, but sock juice isnt quite so nice
Have you seen one in the U.S.? I mean the cane juicer, not the sock sqeezer :)
ive seen the odd in in farm sales in the UK, though i dont know why, we grow sugar beet not cane, perhaps it has other uses? (apart from socks)
This viewer has gnawed on quite a few peeled can sticks when a child. Grown, harvested, and boiled quite a bit too! Another very good video, K.
Thanks for sharing the project. It would be cool to see the mill.
Keith, Interesting to see a plastic being machined, works a little different but mostly the same results. Thanks for all the projects being shown, don't know how you find time to work on everything.
Owning up to a mistake is something real men do.
Respect, sir. 👍
Glad to see some plastic. Oil impregnated nylon also makes a great bearing for low speed applications. There are many types of plastic useful in the shop.
Thanks for the video. I would be interested in seeing the cane mill. The last and only one I have seen was about 69 years ago in Oklahoma. They were making molasses. Distractions are the enemy. Old Bozo knows how to provide them.
Cool ! And yes if you get a chance the video of the part working in the cane mill would be nice if not maybe your friend might take a shot or two for you to share with us. Thanks.
Ha! A shop visitor "Mr. Bozo" came in. I like that, good way of saying a mistake happened.
Good one Keith, even the best makes mistakes...
I have been following your channel for several years now and I love your videos. It is funny but I have been looking for one of these mills here in Louisiana. I have a good cane crop and would love to make some syrup.
Not a boring video at all. Well don, Keith.
Love axis access, even though it sounds redundant! Access along an axis makes boring less boring.
Good one Keith , Bring on the cane milling
It's about that time of year here in South Mississippi too! Thanksgiving is when lots of folks make syrup here, more available free labor. You should trade labor for a couple of cans.
That mill is sweet (envy).....enjoyed the video
It's a shame that we often feel compelled to congratulate people for taking ownership of their mistakes, but it's cool that you included it in the video
scary bandsawing, stay safe keith!
THANK YOU...for sharing.
Just a friendly tip keith. Dont put a red bar across the bottom of the tag picture. I always scroll past you videos in my subscriptions because i think ive already watched them 👍
hello keith, ....i thought you said it was a boring video !. but i found it very interesting .....Lol
Another very interesting and informative video. The overcut that was made on the part, I doubt that it would have any influence in the integrity of the part as the bearing surface is quite large.
I realize it is quite randomly asking but does anybody know of a good place to watch newly released movies online?
@Khalil Ty I watch on FlixZone. Just google for it :)
Golden's Cane Mill? I had to look it up...built right here in Columbus, GA @ Golden's Foundry!!!
Perfect Patterns South (local too) seems to be their go-to foundry castings pattern maker.
They still grow a lot of Sugar Cain in Louisiana, its a major agricultural crop there.
Keith - you can use those shavings to put on your outside window sills for Christmas! Georgia Snow! Makes me cold just thinking about it! 😨
Indeedy! I like that idea for fake snow! ^^
1:05 -- As a Northern boy, I'd heard of sorghum, but I never really knew for which purpose(s) people used it. I was watching a cooking video yesterday, where the cook was complaining that some recipes for apple cake included molasses, which tasted too strong (it overwhelmed the taste of the apples). But sorghum syrup sounds like the sweetener that was intended -- stronger tasting than honey but milder than molasses.
The cane mill would be interesting to see. Where I live sugar is made from beet which is a single step process.
Hi Keith I found a type of plastic that is great for bearings and abraisive wear surface from mcmaster carr. Its MDS infused Nylon and it found it will outwear any thing even teflon in some if the harshest aplications. Ine apokication it outlasted teflon that hadn't to be changed every six nobths by seven years
Hi
I guess I am surprised you did not lower the table insyead of fooling with the band saw.
I still watch every vid you put out.
Thanks
Dennis Williams , Boring bars are great for boring and enlarging existing holes, but fail at creating a hole.
Dennis, I wondered the same thing even though it probably didn't take much longer if any longer to use the band saw. I don't understand where
Tom is coming from though. He is correct that a boring bar is not used to create a hole but Keith wasn't making a hole in this video and the boring bar would have worked fine used as you suggested, which I'm sure you already knew =)
Great video. I'd be interested in seeing the cane mill. Mr. Bozo gets around :)
Yes, enjoyed that and would like to see the cane mill in operation too. What was the shaft clearance you were working to. Not sure of what’s recommended for that plastic however it’ll have a low melting point so care must be taken. Regards.
I mess with a fair amount of Delrin and Nylon.. I find that a nice sharp high speed tool with a lot of back rake works well.
I think for cutting plastics it is beneficial to have a much bigger rake angle on the tool, so that it does more cutting and less scraping. Should also get rid of the fuzz.
There was a vertical roller cane press near here, last time I looked at it in passing the old hedge tree that was fastened to it for turning it had fallen off. It looks like it has been removed ... or the brush around it has grown enough to hide it. I hope someone took it to restore it, and not some scrapper. It was in pretty poor condition, it would likely have been more of a challenge to rebuild than the Vance.
Hi Keith
Wohlhaupter? Brazed Carbide insert tooling is really semi-finished; I've always had to finish the grind.
Keith, I find that carbide tooling used as shipped, especially with coatings, isn't sharp enough for plastics - especially UHMW Polyethylene. A sharp HSS tool with a high positive rake will do a much better job. Just have to get the speeds & feeds right afterwards. You should try machining Delrin plastic. cuts beautifully. just not good for bearings though.
Looks like the shaft of the bit was jumping around. Will it jump and ride on the surface above the area to be cut?
I noticed you set the center for the boring bar just a touch below the top of the block. That would make the bore a bit low (i.e. the legs on either side of the bode a bit long). Or did you surface the two legs to be on center after?
it only pushes against a gear shaft, one block only not a pair, a bolt pushes it and thus it gives adjustable clearance for the sugar cane you are crushing
Hi Keith, having never used a Horizontal Boring Head. before I have 2 questions, 1) for the roughing out, how would it work if you raised the bed up into the cutter for hogging out the bulk and then adjust the radius for finishing? Although I'm thinking the answer there is as you stated in the video, you wanted to become more familiar with the boring head. And 2) could you not leave the “fuzz” on until your finish pass /s, letting each pass remove the previous passes fuzz
Thank you again for giving us a great video I enjoyed it very much!
1.Would have worked fine
2.Yes
They seamed logical to me, thanks for your input Steve.
Keith, are you making moonshine or something? :-) Love these videos.
So what holds that bearing cap down? I saw a dimple in the center of the original cap, is there a dog or setscrew that holds it on?
a bolt, that pushes it to a shaft in the machine, it only uses one bearing block, and you adjust the bolt to give the clearance you want to crush your cane
the guys from planet Bozon get around to every shop
keith how did you measure for the finished bore size? did you mill the block down to the center mark before boring so you could use the distance across as your bore size.. the horizontal spindle realy makes a easy job of this. thats a mighty impressive boring head you have there. glad to see you able to get back on matching videos. looking forward to more .
I'd bet money he just used calipers to measure at the widest point being that this was not a job that required tenth tolerances. What do you mean back to making videos? Keith has put out 3 or 4 vids in the past week over 15 in the past couple months....
Just wondering.... Would it not be best practice to have chucked that plastic block between a couple of thick big width ( exceeding the height of the block as located in the vice ) parallels on the outside to spread the pressure of vise jaw across the whole of it? Of course I don't know the material so perhaps it stays dimensionally accurate being nipped in the vise that way. I'm just asking because I have to make some parts in plastic (unknown what actual plastic) for an electronics project soon...
Wondering if you considered hogging by raising table in small amounts rather than sawing?
a Keith.. on your kalamazoo p 45. is there a reason why you picked that model? that model was a mass produced? is there a better model with the same style.... not in to modern things i like the the history, looks of the older machinery . thanks
hello keith
I certainly understand the frustration with your untended association with Mr. Bozo as we are all perfectionist when it comes to chip removal. The finished product is a direct reflection on us as we would like it to always be positive. Use this as a learning experience and develop a means to prevent accidental engagement of the x-axis so you don't mess up an extensive project during the very last step. BTW, you are forgiven.
Keith,
Is that material self lubricating or will it. be lubricated when it is in the machine?
Ian Butler Depends on the rotational speed and some food processing do not allow to use any kind of lubricant.
another video on yourube used lard, its a very slow rotating part, and lard is edible anyway
Thanks.
That horizontal mill sure would look good if it was green
Not a fan of plastic my self keith , Bozo is always around every shop ..LOL.. You did fine man .. Thumbs up !!
Material like that cuts better with a Tool Steel cutter rather than Carbide.
Nice job. I have a stool for Mr. Bozo, But he has not been here in a bit, I guess he has been to the South east.
We need for someone to take a wall map and track his movements. He got me good this last Sunday, got Bruce the next day. I suspect he's got some kind of pocket teleportation device, stolen from some top-secret lab. We should get that away from him, and use it to exchange our surplus tooling..... ;-)
I find myself surprised that you can obtain a super accurate cut when the boring bar and, especially, the heavy head is off center and rotating at a high RPM. Plus the possible deflection of the long boring bar. I suppose there are two mitigating factors. The material is soft as compared to steel and the heavy casting of the boring machine is the stabilizing factor.
The same accuracy is easily obtainable in steel as that is what the tools were made for. Yes the bar does deflect as does every tool and material to some extent, but this is mitigated by either keeping a constant feed rate so the deflection is consistent or by taking a smaller finish pass.
I’d like to see how you measured the diameter of it.
hemiram05 I wonder as well. Perhaps by placing a flat block on top of the flats, measure with a snap gage and double it? Seems that would be more accurate than using a caliper alone?
Charlie Romeo that would work as long as the top of the piece is at exact centerline of the circle but I don’t believe he was.
Distractions cost so much. I don't know how many times I have suffered because of distractions.
My dad always said if you never met Mr. Bozo you never did anything.
Watching the video, I see the cutter is going through a period of wobble and then settles down a little smoother and then repeats that sequence over and over again. And that seems odd to me. IDK
I find that when using a Dremel on plastic (as close as I come to machining) light and fast is what works best. Don't dwell because it gives the plastic time to heat up and melt.
Mishn0 fast yes, light depends on the tool, .050 per pass may be about the minimum depending on the radius on the end of the carbide.
Please, Keith... Show us your screw-ups! We all make mistakes, even accidentally engaging a feed screw. It would add so much to your channel to show us, rather than simply owning up.
Or include them as an outtake reel at the end of the video.
THE PLASTIC IS CALLED DELRIN .
the trick with plastic is lower rpm
I would have just put a big chamfer in there
Nexfero , on both sides!
10/4 on the cane mill and I doubt a mule will burn that bearing up. And watch the Bozo's and Brian is in hot pursuit!
i heard moo tech needed a little help and you blowed him off, whats wrong with helping some one out or do you not do that
he also contacted abom and mr pete, none of them got back, the big guys get too big for their boots, enjoy all the freebies, but as you notice, dont even come into comments anymore, keith used to pride himself to reply to everyone, which of course was unsustainable, but to suddenly go to none at all....dissapointed, lets hope at least the fan base isnt rabid and tribal like mrpetes and abom has become ,where you cannot even mention anything bad
WD 40 will help...it doesn't cure it but it will reduce the fuzzies that hang on the edge like that
Keith,
Fine video. I would have used two blocks and bored down the middle. The customer would have a spare in case it wears faster than expected..
I don't get it. This is not boring at all?
WTF! Don't tell me that you forgot to lock the X axis.
Judge Judy will yell at you if you say basically one more time.
Eh, don't sweat it.
@11:15 Good practice is to work out the travel of your tool before you start. A moments thought would have presented a useful and solid example to your viewers. Why do you present yourself in this way?
The quality of that boring bar is horrible. Seems BENT. AND yes I know he is using a boring head.
What a boring video.... What do they power the mill with? Animal or electric. I helped at a demo one time with a horse mill on it and you had to time standing up... And watch where you walked.
@11:32 you risk over-riding the plastic chips on the vise ways. Poor example of workmanship for the sake of a moments thought.
A little too much time on this one.
