Cement Mixer Restoration Overview


Randy Richard in the shop well right
outside the shop and this is a cement mixer it looks a little beat and it is
it’s old my father picked this up in the early 60s and it was used then I’ve had
it for a long time and it’s been used a lot
needs a little work I haven’t used it in a long time I just got it back for my
brother-in-law he had it for about 20 years I want to get it running again has
an electric motor that I’ve removed already comes so we need to look at that
anyway let’s walk around and take a look at it and get an idea maybe what we need
to do about it well this is the operator end of it up here this is a hand brake
and that really doesn’t grab too good we probably have to take this apart and get
that working it spins nice and freely I’ve chipped off all the old grease off
everything that was just oozing everywhere it was rock hard this seems
to have a little play up in here but not too bad I think we could probably do a
little work on this the brake part and get that to grab like says it does it
spins fine the things are pretty heavy this is a this is a casting with an
internal gear and an opinion in here the casting this arm is a casting this
bottom part of the drum is a casting so that seems to be good so really you
know but sad that paints all coming off and rust and stuff
I need a need I need a needle scalars what I need maybe a trip to Harbor
Freight or something and to really get this cleaned up better here on the drum
there’s been some welding welding probably some cracks you could see some
cracks on the inside and actually this rod is so shiny here I wonder if
somebody used stainless or something on it but it’s that that’s gonna have to
get ground down I think and rework that it’s pretty pretty bad pretty bad lots
of inclusions there it goes clear up here yeah well we’re gonna have to grind
that probably and see about maybe doing something else with it
this is the back bearing of the yoke for the drum and these bearings I bet are
plain bearings and they just got grease fittings on them there’s another bearing
in here for the pinion that goes through to drive the drum to the back this is
where the electric motor was mounted I’m gonna switch up here I removed all that
already the motor was just humming so we’ll see about that says it’s a
capacitor start motor one horse general electric motor it’s a big motor it’s
nice to have an electric you can just turn on and off when you need it real
easily otherwise I might even find that gas engine to go in here but all this
turns pretty freely there’s not a problem with all that and these little
bushing bearing blocks here seem to be awful lightweight for this but it’s been
working for a long time like this we’ll probably have to take all this out at
least get this cleaned up and working good and then readjust the end place
about a quarter of an inch and it wouldn’t even ooh belts of course
– but I think I’ll probably tear all this out and get this cleaned up a
little better this is the other side and there’s been some repairs on the housing
for the drive the angle irons and weld at the end this hole was originally here
this is probably for the smokes back where the engine used to be and general
deterioration of paint and still even on this side of course and it really needs
a new set of tires they’re pretty bad they hold air but they’re pretty tough
shape and you can see that just by turning my hand I can freely turn this
now down inside the drum here and there is a cap on the center spindle that
would probably take off looks like it’s been leaking
there’s probably bearings in there so we could probably take that off and clean
that this matters how involved I want to get what I pull the drum off or not this
is a kind of a two-piece kind of drum gotta get the echo going there this is a
two-piece kind of drum this outer parts been riveted on to the casting where
they wear the gear the ring gear is and there’s some good cement buildup on
these mixing blades inside I should chip off then there’s some other build up
with cement that got left it should be kind of chipped off and what else can we
see we could see up in here where the cracks were they welded that piece in up
and hi there we’ll have to see what we can do about that maybe clean it weld it
on the inside might be a good idea so we’ll take a look at that this is a
three and a half sack mixer these are a couple of nameplate Center on here now
it was made by the construction machinery company in Waterloo Iowa which
is pretty cool it’s three and a half s mixer so that’s standing for three and a
half sacks and they tell you how its certified for three and a half two that
connects three and a half sacks of concrete mix plus water I think it says
on there so it’s actually been certified the AGC
standard they it’s been stamped and everything looks like a little mason
symbol actually on there this is gonna be a little tough to maybe clean up I’m
gonna probably have to take those off and clean those up here’s the motor I
sent you big motor General Electric tri clad capacitor
motor yeah one horse sixty Hertz dual voltage 115 230 motor
I think they 1720 says on there for our p.m. yeah about 10 inches diameter it
still has the name plates on it the wiring for the wire is set up for the
dual voltage and it does turn freely so that’s a plus we’re gonna have to take
this thing apart though so there you go quick overview of the mixer this is
probably gonna be a little bit of a long-term project hey pretty busy this
summer but I’m gonna at least get started on it here and just work on it
bits of pieces maybe into the winter or even like I said it’s a little bit
bigger project and I have a lot of things to do this summer that I’m trying
to get done so we’ll uh we’ll plug away at it and we’ll start off with the motor
and then we’ll put tear apart that probably that jackshaft in there get
that done and then we’ll start looking at bearing caps and things like that on
the drum so stick around and we’ll catch you in the next one thanks a lot you
guys

  • I really enjoy the fact that you’re willing to fix/repair stuff rather than just chunking it and buying new. Keep up the great videos.

  • Amazon needle scaler.On a recommendation from a colleague , I have been using this one for about three months pretty steady. Still going strong. ref=ppx_yo_dt_b_asin_title_o04_s00 worth the $28 bucks. No idea how long it will last, I know I have gotten my 28 dollars worth of work out of it and then some. Aa a welder by trade it is certainly not my preferred method of tool buying, I tend to buy top quality tools for the long term. However that is becoming a gray area these days! Anyway…. I needed something quick on a low budget.  It's cheap enough to throw out if need be and get another. Cheers have fun with the cement mixer, I try to avoid those things 😀

  • 👍👍 need to redo mine as well. I couldn't get mine slow enough with a single phase motor. Tossed a 3 phase on it and ran it from my vfd….kinda limited distance from my shop but that's where I use it mostly… prevent folks from borrowing lol

  • Hi Randy, nice mixer compared to our HF orange one, we rarely use, yours is important because you have had it in the family and it after you, it is to head over to your sons place following you someday, so a great project indeed, thank you for sharing it.
    Lance & Patrick.

  • Morning Randy! Be careful when disassembling that mixer, it's alot heavier than it looks. This will make another good series.

  • It's in very good shape for close to 60 years. I wore out my mixer. It looks similar but probably not near as well built as yours. Take care Randy.

  • hey Randy,
    i concur with many of the other folks that this would be an excellent project to follow along. there's some real potential to make the ol' gal shine like when she was new. those old machines were built to last and something like that is worth restoring back to working order…

  • The mixer is well worth saving.  You won't find anything new like that.  Am looking forward to seeing you rework it.  Thank you.

  • I have that same motor in a 2HP version on my 1957 Devillblis air compressor. You can find the capacitors on Amazon for about 10 dollars each.

  • This will be a great series, looking forward to it. I know Mr. Rucker swears by brazing cast iron. I wonder how that would hold up on that drum?

  • Most of those cement mixers had a Wisconsin engine on them. It's been a very long time since I've worked on one.

  • Very cool Mr. Richard. I enjoy watching restorations for some reason, looking forward to more.

    Speaking of HF I hear nothing but good things about their predator engines if you decide to go the gas route. No personal experience so just hearsay.

  • Sure looks its age but … hardly surprising!
    Was just thinking needle gun then you mentioned it. Lot of potential – an old Briggs might serve for power – the old one I had long ago was a Briggs powered. Maybe elec motor might have some life left.

  • This going to be a great resto Randy! Looks like a really nice mixer, can I borrow it when your done, hahahah…

  • Graet project Randy, but beware, the greatest "Shock of my life was grabbing on the handle of an electric cement mixer⚡️. It's not a ship Randy, cement mixer have an exhaust pipe.🚢

  • Hi Randy,
    Looks like another great project to document and share.
    I'm going to look through my pile of motors and see if I have a 1 horse 1720, 110/220. I know I have a couple of 30 HP ones maybe a bit too big!!! lol

  • so here is my take, randy. Mr Pete has a Hercules engine he's selling.. that might be fun to tidy up and fit. lol. just making it interesting. you're welcome 😀

  • Just thinking out loud here about your order of operations. Perhaps before you paint and clean the outside, get the motor working and put some dilute muriatic acid in the drum to eat the concrete off the parts. By having the motor operative you can let the mixer provide the elbow grease for that step.

  • The welds on the bottom of the drum were probably done with nickel rod since the drum is cast iron. As far as the motor goes, where is the capacitor? I’d check that and the centrifugal switch that takes the capacitor out if the circuit when the motor gets up to speed. Capacitors have a habit of failing due to age, and that motor looks to be 1940s or 50s vintage.

  • Yo Rando! looks like a fun project, will be sure to follow along. Years ago I bought a used Stone Contruction cement mixer for $800. Used it (abused it?) for a lot of years, built my shop, etc., then sold it for $1800. I live for deals like that. All things considered, I'd say your mixer is as much a family heirloom as it is a tool to get work done. Randy for President 2020!

  • If it's too nice and clean, it may end up in the kitchen as a food mixer… 👩‍🍳👩‍🍳😋
    Yah…!!! Summers are always too short… 😎😎

  • I wonder if a wet sandblaster would be a good option the clean up the mixer before you paint it. Keith Rucker had pretty good results with the unit he purchased.

  • Just started to watch part two of this one and just as Randy said "I'm a Trump suppor…" black screen, "video unavailable"! Now that is fast "conservative shadow banning" !

  • Why has the Red Trump 2020 hat video been taken down? I watched it on YouTube on TV and wanted to say kudos to you Randy for having the balls to say what you think. If YouTube took this down because of politics then YouTube sucks.
