Monster Shear

Recommended Posts

I was just down at the salvage yard, looking for some rebar to make some anchors because the hardware store wanted $20 bucks for a little piece,

anyways while i wondered around looking at all the odds an ends i decided to take a picture of this giant old shear setting out there,

i know the shear came from a previous salvage yard that had been here since the late 30s but I’m not sure exactly how old the thing is,

at one time the previous owner had a giant antique diesel engine running it and the next owner hooked up a PTO shaft to try and run it off an industrial tractor,

but I’m pretty sure when it was new it probably was ran off steam because this thing is massive I’m guessing 10 tons or better my pictures don’t really do it justice

Ooooh, that's a beast Billy, I'll bet it'd fit in your shop nicely. Did you make an offer? Were it to fall in my lap I'd power it with a 10hp Wisconsin and pipe the exhaust outdoors.

the series ran up to #5 which could cut 6-1/2" round stock

Holy Mackerel!!! That’s a serious shear! I read that it said it could cut railroad track cold as well, thanks for the link Larry!

nah i didn’t even inquire about buying it, I talked to the owner a couple years ago about it because i recognized it from the auction of the previous scrap yard in town, he brought it thinking he’d use it and put that pto shaft on it and only used it a couple times before deciding it wasn’t worth the hassle of messing with, it’s set there ever since,

I was at that auction years ago i bought some really nice old stuff, 

i remember it was pouring rain and 30 something degrees outside, the mud was a foot deep and there wasn’t a whole lot of folks there, 

stuff sold cheap, if i remember correctly I think some of those giant machines only brought  a few hundred bucks, the local towing company with big crane trucks was the only way to get that stuff outta there and hauled 

I’m sure this guy would sell it but he’d want scrap price for it so it’d be more than I’d wanna pay,

as far as running that thing I think a 10hp Wisconsin would probably do well as a pony motor for something bigger lol

Didn't Larry say above that this one called for a 7 1/7 hp. motor? If anything a 10hp Wisconsin would be underpowered. HP ratings on electric vs. gas engines don't match, elec. is significantly torquier.

As the old saying goes, "horsepower sells cars, torque makes them go."

Slow running diesel, as it was designed for steam.

your right!

i didn’t see that part of his post, when I first replied, 

I was just basing it off motors I work with, there’s just no way a modern 10hp could turn this thing over without some sort of gear box helping it out,

these modern ones stall out under a much lighter load than that thing would put on I would think, I can bog down 20-30 hp Kawasakis just putting heavy loads on them in the field mowing grass if it’s tall and thick enough 

your definitely right again,

old hit and miss engines that said they where 10 hp from what I’ve seen are much larger than a 10hp or even 15 hp gas motor now days, and I’d assume have much more torque, 

I’ve got a 14 hp kohlar running one of my compressors in the shop and I just don’t think it would have the guts to pull something that big

but I could be wrong, I’ve been wrong lots of times and I’ll be wrong again in m sure! Lol

next time I go back to the Clara yard I’ll spend some time looking at the drive and the gearing on that thing to get a better understanding of it and I’ll get some pictures too, 

I’ll ask him what he we would want for it to although I have no clue what I’d do with it, I don’t make a habit of cutting 3” stock or forging anything that thick

The math is simple

Power = rpm x torque.

So 10hp running at 100 rpm has more torque than one at 1000 rpm.

And the use, fit very nice as a conversation piece next to your driveway.

Oh I don't know George, maybe if you had 200 penny nails to trim?

There is one minor typonic correction to my above post, I meant 7 1/2 hp motor rather than 7 1/7 hp. motor.:rolleyes:

It would require serious gear reduction to make a 10hp gas engine suitable. It's been many years but we drove our portable Moyno pumps with 10hp Wisconsin Robin engines. Were relatively low rpm. engines but plenty torquey. Moyno pumps develop a lot of pressure without stalling or blowing fittings but don't like high rpm. They're designed to pump thick fluids like peanut butter (literally) and when we were using drilling mud we needed the push.

Sorry for the stroll down memory lane but I developed a serious affection for the Robins. I'd rig a jackshaft and mount one right up to one of that shear. :)

After freeing it up so it moved smoothly of course.

I don’t hardly see Wisconsin engines anymore, occasionally the new robin engines pop up, I think they are made by Subaru now, 

most of the engines I work with are way higher rpm, I’ll have to check my tech manuals in the morning when I get to the shop but I believe that even the Briggs and Strattons are running 3k when your testing the charging system,

Most definitely not! I’m pretty particular about the cut on my cigars! lol

firewood cutting service

Firewood has become quite the hot commodity around here lately, just five years ago a Rick of wood was only $50 bucks now it’s $75-$80 local and the larger towns it’s $100 on up,

it’s actually becoming cheaper to run natural gas than burn wood anymore unless you cut your own or burn saw mill cut offs

Jerry 

yeah those older engines were a lot more stout,

I’ve often wondered how they claim a v twin lawnmower engine is pushing 36 hp when my Kubota 3 cylinder diesel is only rated at 15 and same for my air compressor engine claiming 14 hp and it’s not to awful much bigger than a tiller engine

I think it's marketing and donations to the right committee members. HP is torque x rpm. Anymore they measure rpm at the point the motor / engine self destructs.

I believe where it really matters HP is measured by amps or kw.

I do like cigars! But nothing that big! Lol

sitting in my front yard

Scott

ill check am see what he’d want for it, but even at scrap price that thing would probably still be a few Grand!

  I can afford a few grand on a giant shear to sit in my front yard.  I bet I smoked more than $10,000 dollars worth of ciggarettes before I quit.  Calculate in the beer I drank when I was young and all the collateral damage and I suppose I could afford 10 of those shears.  How much is shipping?

I wish that's all I spent. After promising Deb I'd quit and working at it for a couple years I sat down and figured out how much I'd spent. If I'd quit when I said I would we could've bought a new car and most of a new pickup by time I counted it up. I spent another couple years working really hard at quitting, cold turkey worked pretty well for a week or two but cutting down wasn't. 

My endocrinologist prescribed (Wellbutrin IIRC) as an anti depressant, insurance companies wouldn't pay for meds to stop smoking but don't bat an eye to spend hundreds of thousands to treat you for cancer. Anti depressants? No problem, have a nice day.
