I've heard that "a shaper will make everything but money". Got no experience myself.
That phrase likely coined by contour bandsaw manufacturers. Demise of one, very close to rise of other. Both do things other cannot quite as well.
Not only tremendous size and general facility, but note the floor. World's best industrial surface; wood bricks, they're set on end.
At lower left is what appears to be a drain, probably isn't. It's a cast iron floor plate, near certainty of mounting in front of portable boring mill, large radial drill, or functions as serious assembly table.
oh thsose are just 1/2 boards, thats somebodys diorama dream shop......:idea: entirely too clean, not a scrape on the floor, no wear trails, nutten.no oil stains, no dick stains. cant be real.
I wouldn't go so far as to say too clean by any means.
Expand the picture to its fullest then scroll around there is some small cylinder laying on the floor not too far away from the electric motor mounted on the cast iron bricks Also around the shaper there is some debris as well as the swarth from the last or current shaping project.
yes this diarama is quite detailed even the stuff laying around. I bought a 1 inch tall bridgeport years ago to add to my collection.
Look at all of finger/appendage crushing things exposed, an OSHA mans nightmare!
My brothers friend was partners in a machine shop with a WWll vet in the 70's, One night after some adult beverage had been consumed my brothers friend was riding the ram of a very large shaper like a mechanical bull:cool:

Even in black and white that looks red hot...
It does indeed look to be glowing hot. I like how it follows the first rollers, then less and less until it is flat on the last rollers
The rollers look like they maybe glass.

Post *452, pic of near molten glass sheet.
Examining pic again, wondering if they are actually 'rollers' at all. There isn't an apparent pillow block or saddle bearing.
Might they be just forms that glass moves smoothly over? Seems with travel a bit acute to axis of those forms, would impart something like skiving, to reduce the corrugations.
Not sure a perpendicular feed would do that.
so what the one above that apparently comes down...are they making corrugated glass sheets???
That would be SOME product Corrugated glass! Haul that into the local window guy "yes, I'd like this little bathroom window re-glazed with THIS" right before whipping it out of the box......
Anyway, I think the wrinkles appear as it slides/ rolls out, almost like making home made pasta, has to be cradled and laid out to dry. Factory wise, the methods are completely automated.
I'm far behind in google quests; satisfying those (+ me) who want to know.
JUST THINK OF THE SEALER TO SEAL IT TO A FRAME!!!!! possiably snazzy roof pannels or some decreative stuff.
we got off the rong off ramp in texas last week, almost went to wacko. my nagravator was nagavating....

Hmmm. That may be a Texas thing. Headed for Frank S's place, also happened to me, navigator was mislead by places with similar names. Overshot only 280 miles southwest.
Past 3 years, my forays have all been unaccompanied, someone has to mind the pets.
In the car, I take a dog, gets whole back seat. I stop for gas, fill one tank and empty two others, he eats when I do, and never wants 6 hours at outlet malls. He loves running all over property at machinery dealer though.
that makes my wife feel better!!! and she( the nagravator) can now just say it was all the gps...with a smile.

They look like old axles being refurbished
I think those may be rough forgings that are being machined.( bar stock with the ends forged for greater strength)...or not.but thats what it looks like to me. or partial machined then some heat treetment then more machining....or....somethin..
Somebody pinch you-know-who....THIS is infrastructure.
Not day care centers and public murals.

Such attention to detail!

Not likely to get accidently touched. 42" lathe. That is 7-8 feet from the floor and would require you to lean in over the headstock and feed shaft.
I mean the twin coils are "sexy" - that's an engineering term that means "extra effort was given to make this object aesthetically pleasing".
There used to be a fantastic book in the local library called 'Victorian Engineering' and it had many full plate photographs of machines, buildings, bridges, canal locks etc and what always struck me as a young fella was the use of curves, arches and 'unneeded' decoration in all.
Everything seemed to be a work of art tat not only looked right but looked beautiful as well.
I know - I hate how everything in the modern world has been "value-engineered" such that there's no room for beauty.
The 1880 hand-cranked apple-peeler that we still use is a thing of beauty; many castings, even freakin' hearts in the main gear wheel for spokes. Our modern equivalent looks like it wouldn't last ten years. We've got a cider press as well; heavy iron castings; looks like it will last a thousand years.
The curves served a purpose. With cast iron being brittle the curves gave just enough give to prevent things from breaking. This was from the moment it was cast because even the cooling process set up stresses. With steel the material is elastic enough you can make everything straight and let the steel take the strain. It might warp but it is unlikely to just snap.
Right. Handwheels are usually cast with spokes that are curved so that as the casting cools the spokes don't have stress that can cause them to possibly snap.
The exposed dry gears of the lathe engine is scary!
I found two books on eBay, Victorian Engineering by LTC Rolt and Victorian Engineering and Science by Anthony Wilson so I ordered both (used) for $15 and change. I hope one of these is the book you mentioned. I just also found (and ordered) another called "Wonders of Victorian Engineering: An Illustrated E... by Andrews" and another I may 0rder as well.
I also highly recommend reading books on such subjects of The Great Eastern (ship) and the Brooklyn Bridge, two of the most fascinating Victorian era engineering feats I've read up on.
Another fascinating subject is the accurate re-creation of a 150 hp Case steam traction engine by a young man who obtained copies of the original prints from Case and spent a million and a half dollars and thousands of man hours building a replica so accurate that it has some of the same problems as the originals (of which none of the nine originals survive). It is scheduled to be at the Tri-State Antique Engine & Threshers Assn. in Bird City, Kansas from July 29-31 this year. It's a show I've been associated with for decades and I'm really looking forward to seeing that engine run. There are you-tube videos of it. Its HUGE! I understand it to cost over $18,000 to get it there and home! I'm involved mostly in the letterpress print shop and somewhat in the blacksmith shop. I have one of my Linotypes in the print shop which is running (usually) to demonstrate that technology.
