Cement Mixer Restoration | Disassembly P2

[@dwightkrauss]

Had one just like this!! Replaced hit-miss engine with electric motor and building a couple brick buildings, then finally installed a modern gas engine. Ended up giving it to some peeps in Mexico rebuilding after the earthquake. Keep it up, this is a GREAT machine.

[@RRINTHESHOP]

Wow the only two in existence. There is enough room for both the motor and a gas engine. Thanks Dwight.

[@badgebadge8946]

Very good presentation . I have a a much older John Deere 400A. One small tip, put the the nut back on before knocking a threaded shaft. That way you are hitting the nut, and saving the threads.

[@RRINTHESHOP]

Thank you for the info.

[@sharkrivermachine]

You are giving that brass hammer a good workout on this project. Interesting project, looking forward to fixes and reassembly.

[@RRINTHESHOP]

I use it all the time, love it Steven. Thanks.

Watching youtubes like RR to relax & pass the time today while we still have power... Dorian is heading straight for us. We are dead center of the 130 mph wind zone, and the 4+ inches of rain. Fingers crossed. Randy, really cool to have a project with a long family history. Strange to think of a cement mixer as a family aireloom & antique, but that's exactly what it is. And soon it will be ready to keep on serving the family for another 60+ years. Cheers!

[@RRINTHESHOP]

Good luck Arthur with Dorian. Looks to be headed to Nova Scotia. Yep a funny aireloom, but a good one. Thanks.

G’day Randy looks like the yoke bearings are a challenge, possibly line bore it with a dummy bearing in one yoke to support the boring shaft and the other end supported by another external bearing / bush mounted to a frame clamped to the yoke. Have a look at how people machine earth moving equipment bushings in-situ for inspiration. Cheers Peter

[@RRINTHESHOP]

Yep i am thinking on this issue. Thinking for leather bearings. Thanks Peter.

[@pgs8597]

I saw that comment and thought why not as it only turns 1/4 turn most of the time but then seeing RR take on a line boring challenge would make a good couple of videos, being selfish I suppose:-) Cheers

[@aserta]

Built like the proverbial brick dunny. Man, that's a well made mixer.

[@RRINTHESHOP]

Thanks the project is coming along great.

[@TimothyGack]

I'm really enjoying this series so far. Nice progress. It'll be fun to see how this all comes together.

[@RRINTHESHOP]

Thanks Tim. Lots of work to go.

[@RosaStringWorks]

A lot of work but will definitely be worth it.

[@RRINTHESHOP]

For sure lots of work, progressing. Thanks Rosa String Works.

[@billdlv]

Good job Randy 👍👍Looks like a fair bit of work ahead.

[@RRINTHESHOP]

Happy New Year

[@metalshopwithtroy5755]

Hi Randy Great video it mirrors an upcoming project of breathing new life into a similar cemet mixer. Thank you Randy

[@RRINTHESHOP]

Good deal Troy big job. I still have lots to do.

[@ericrichards5862]

Nice progress Randy, that's quite a solidly built machine, I have some large cotter keys if you need one.

[@RRINTHESHOP]

Thanks you Eric, I have the keys. Do you have a HBM that the yoke would fit on, to machine the journals?

[@ericrichards5862]

BTW I have been watching "The Essential Craftsman" also, it's been a great review of construction techniques for me.

[@RRINTHESHOP]

@@ericrichards5862 Scott is very nice, next time I am up there I will go see his Blacksmithing shop.

[@ericrichards5862]

@@RRINTHESHOP Hi Randy, The only HBM I have is a small Hardinge with a 3" x 12" table. Can you set it up perpendicular one end at a time on your mill?

[@CraigLYoung]

Morning Randy! Great job getting it apart.

[@RRINTHESHOP]

Morning Craig, having coffee. Lots of work but coming along.

[@AmateurRedneckWorkshop]

Love that John Deere. I see you have good taste in tractors. You certainly have a big job ahead of you getting all of that stuff restored.

[@RRINTHESHOP]

Thanks Harold. Lots of work ahead. Trying to get it all cleaned and at least primed before winter comes, and it is coming fast here. I love my tractor.

[@outsidescrewball]

enjoyed....surprised you don’t have a roll out work table so you don’t have to put tools on the ground....just me thinking since I am older and the ground is SO FAR down...lol

[@RRINTHESHOP]

Something I will have to work on. But it keeps me young. Thanks Chuck.

[@MaturePatriot]

A worthy project. That John Deere is a back saver! Take the yoke to the shipyard, they can turn it. Be careful and watch the pinch points.

[@RRINTHESHOP]

Thank you Vernon, I am a bit far from a ;yard, The JD was worth every penny.

[@donmittlestaedt1117]

Thanks Randy. Appreciate that. Metal working is where it is at.

[@ActiveAtom]

Nice to be here for P2 Randy, a very happy Saturday too you. Happy Birthday Aunt Randy 90 wow why to gooooo. We like that you could visit the tool grinding company that made the one yellow one you restored we really liked that rebuild. That mixer how many yards is way bigger then the one Patrick Lance use around the property, ours is a through away. Lance & Patrick.

[@RRINTHESHOP]

Thank you Lance and Patrick. This is a big project. Trying to get it painted before winter, lots of work.

[@ChrisB257]

Sure helps having the tractor... more great progress for sure. :)

[@RRINTHESHOP]

Yep love the tractor Chris. These parts are very heavy.

[@woodscreekworkshop9939]

Having a tractor is so handy!

[@hilltopmachineworks2131]

Either that or a forklift. Not sure which one I want to buy next.

[@woodscreekworkshop9939]

Hill Top Machine Works why limit yourself get both 😂

[@hilltopmachineworks2131]

Woods Creek Workshop Oh I do want both. My bank account says otherwise. 😄

[@RRINTHESHOP]

I love my tractor. It is also my forklift.

[@bcbloc02]

Was there babbit in those bearing housings or did they just run cast on cast?

[@RRINTHESHOP]

Cast on Cast. I am thinking of a bit of an up grade to leather. Thanks Brian. If you were closer I ould send the yoke to you to have the journals machined.

[@TraditionalToolworks]

I started watching the Essential Craftsman a week or two ago, he's very helpful and his vids are XLNT.😉

[@RRINTHESHOP]

Good channel. Very nice people.

[@pierresgarage2687]

The great news about that mixer is that not much is over worn or broken, it should get back to full duty with minimal work and a good coat of paint. OK....!!! I have to admit, it's heavy... 😝👍

[@RRINTHESHOP]

Just a bit of work? This is a hugh amount of work and the parts I have to use the tractor to move. It is progressing along. Thanks Pierre.

[@griplove]

The essential craftsman is awesome. Enjoying the restoration thanks for sharing. Sorry to hear you had to edit a video.

[@AWDJRforYouTube]

That mixer will be well worth it when it is restored. NOTHING is made that well today!

[@RRINTHESHOP]

Happy New Year

[@josephmagedanz4070]

Well, at least it's not rusty under all that grease. How will you redo the yoke bearings? Thanks for sharing.

[@RRINTHESHOP]

Yep Joe the yoke bearings are a big question right now.

[@windyhillfoundry5940]

Coming along nicely👌, I wonder if the yoke bearings were babbit

[@RRINTHESHOP]

Thanks Clarke. There were no bearings, cast iron on cast iron. I am tempted to put in bearings. But I have no way of machining the journals on the yoke. There is a slight amount of wear on the bottom of the bearing housing and a small amount of wear on the journals.

[@windyhillfoundry5940]

@@RRINTHESHOP I wonder if you could get away with line reaming these with the caps bolted back on. But then you have the roundness condition of the yokes ends to contend with if you added shim bearing material. My great grandfather used leather as bearing material for a bearing surface on a cane mill I have and it held up great. I guess he saturated it with grease prior to assembly. I would try that no more than it will swing, id even mix in graphite with the grease

[@RRINTHESHOP]

I will show all the issue there. This would be a big job and I don't have the equipment to do what is really necessary. The journals and a bit out of round and tapered all due to wear, I could bore and the bearing caps and make a bronze bearings, I would make them with tapers to self align. The journals would need to be turned, that is where the big problem would be. I need Brian Block to set up in his big lathe to turn true. Now I like the leather idea, I will look at that.

[@RRINTHESHOP]

I think the leather idea will work great for this, check this out. theoldmotor.com

[@scrout]

That mixer is a beast. Your tractor have some kind of portals on the front axle? Nice wide stance and ground clearance.

[@RRINTHESHOP]

The tractor is a JD 1070, 4wd, 40 hp. Great tractor.

[@webtheweb]

I have mixer that has a cap in the drum. Anyone know how to remove that cap on the drum? It's a issick model 350

[@RRINTHESHOP]

Ok.

[@smithbadwin8937]

hi I am looking for the parts manual for this mixer

[@RRINTHESHOP]

Good luck. I could not find anything.

[@henryunderwood1220]

Bought one just like this. Do you have the bearing number or size of the bearing by the large pulley? Mine is completely gone.

[@RRINTHESHOP]

I made my own bearings. I have no info on the mixer.

@@RRINTHESHOP Thank You! Enjoyed the video.

[@garyjones7198]

Randy how heavy is the bucket on that mixer? Btw.. very nice job...

[@RRINTHESHOP]

Very heavy 100's of lbs.. The lower portion the gear down is a casting about 3/8" thick plus the shaft hub all one piece. The upper portion is sheet metal about 3/16".

[@HolzMichel]

this has been an interesting follow along Randy, by the way have you seen or heard anything from Don Cossit recently? i got to meet up with him 2 years ago in moscow but there has been very little going on with his channel and you don't see any of his comments in other machinist channels...hope he's ok

Ha ha, "bearing clearance".

What bearings? lots of clearance, thinking of leather for bearings. Thanks Phil.
