Concrete vibrator info

I need some information regarding concrete vibrators. Does the head and shaft come in one piece, or two? Are there places where one can have longer shafts fabricated? Are they serviceable? Do you know of any sites where I can find information regarding these questions? I come upon millions of sites, and they are all full of information, but I haven't really found one that answers these questions.

I don't know squat about the workings. . . But after my brother-in-law brought his 30A work 'donkey dick' to the house the day we poured 40' of footing, I became a believer.
I spent $80 on a HF job before I poured any more concrete. although it doesn't get used as often, it ranks right up there with the compressor on things I can believe I didn't buy years earlier.
No serviceable parts on that one-- but I've grabbed it once or twice a year for the past 5-6 years and it works every time.<g> [and it is worth *way* more than $10 every time I use it, so I'm ahead of the game.
One of these days I'll see how it works for 'fiddling' night-crawlers, even though I don't fish anymore.

I worked as a concrete form setter in my younger years, two of which were pouring high rises in Houston. A concrete vibrator is one of those things that you didn't know you needed until you see how damn well they work.
I want this one for underwater use, and I have already discovered that there will be too many problems from a very long cable, and the inner workings, so will go with an air actuated vibrator. No moving parts, replacable in five minutes, and cost around $175 per unit. A cable driven unit would require its own engine, have a long cable, that cable would be subject to fraying and breaking, and it would take someone with half a brain to keep the whole thing operational if it did take a dump and require repairs.
One of the parameters of this venture is to keep everything simple enough for a teen ager, standard sized everything, simple design and function, fewest moving parts, and easy replacement in a modular fashion.
I thought of the concrete vibrator, as well as another poster, but on investigation, it's just too many moving parts, it needs upkeep, needs a dedicated engine, and if it is dead in the water, so is your gold recovery operation.
But I still want one for working around the house. I've tried using a rotohammer on rebar in a form to shake out the bubbles, but nothing works like a vibrator, and the finished project will attest to that.

Hit yer local tool rental business. They typically rent to contractors doing one-off jobs and probably have some info. Once I saw one in action, I understood perfectly. Twenty to thirty seconds is all it takes for you to know all you need to.

My experience is with Wyco vibrators
The Wyco vibrator that I used (for 10 years) consisted on a motor, a shaft assembly and the vibrator head. My original use was on 14' tall by 24" diameter columns so we got a shaft extension that gave us a bit more length.
My vibrator is similar to a 992A http://wycotool.com/index.php/all-products
so to answer your original questions (as related to unit above)
Does the head and shaft come in one piece, or two? motor, shaft, head
Are there places where one can have longer shafts fabricated? Wacker sold them as stock parts Are they serviceable? yes, very
Do you know of any sites where I can find information regarding these questions?
Wyco is a professional tool (ie $$$$) I don't know about the Makitas, Dewalts,etc
Take a look at ebay Item number: 180770871685
If this is just for some DIY work, consider renting on Or buy one on ebay or CL and flip it when you're done.

I bought a Wyco vibrator about 11 years ago. I don't know if mine is exactly this model, but it looks identical:

I think I paid $600 at the time. They come with shafts of different lengths - so if you're going to buy it new then buy the one with the shaft length you need. As Bobk says - you can remove and install different shafts (I've never taken mine apart). Mine has either a 6 or 8 foot shaft.
As for vibrating too much to cause segregation, that shouldn't happen if your mix has the correct proportions (of sand-to-stone) and doesn't have an excess of water.
The point of having a vibrator is that you can make a more thick mix (not soupy mix) and the vibrator will do the job of helping it flow where it needs to go when it's placed.

I'd say that is a very personal decision that the user should decide if a longer shaft is needed. I'd think though, that concrete would chafe and possibly irritate the inner linings. Be sure to lubricate it well.

dont over vibrate or the aggregate will all move to the bottom leaving the top area weak. aggregate creates strength

Years ago, a young woman told me a joke she said she didn't understand. It went, "Where to macho women get their vibrators? answer: Black & Decker." The young gal knew there was a joke in there but didn't get it. ^_^
