... Let's look at http://www.vxb.com/page/bearings/PROD/Tapered-Roller/Kit14233 and think about that as a spindle bearing. Static loads of 480 KN (100,000 ...
Hi: I've been lurking for a while and thought I'd offer some comments on this thread. You folks might want to compare the giant lathe under discussion in this ...
Here is a link to a company that does the type of work that these guys seem to want to do. They do it onsite and much of the time with large portable machine...
As I wrote earlier and Chris is saying the same thing here a fairly substantial amount of engineering would be required to see a project of this magnitude...
I first read about a huge turn of the century lathe a few months ago. It wasn't until I read Chris Green's post about the modern largest lathe that I...
... Update: The big SNK lathe runs 500 KW (670 HP) on the main motor. With common efficiencies, we would need 1 MW (yep, a million watts!) just to run this...
I don't think a conventional lathe is necessary (or appropriate) for this sort of thing. Currently the work is done by equipment trucked in from the US. A...
This is what they are doing: http://www.metallisation.com/videos/library/arc-spraying-video.html Well, they are doing that on a large scale. The person who...
In addition to spraying finishing the surface of the main body I'm sure much of their work will also entail refurbishing of the roller journals for remounting...
... Those are amazing: a 10.5 foot long spindle with a 30" spherical babbit main bearing, plus a 20" plain bearing at 9 feet to fight the torque , 18"...
back a hundred yrears ago or so, large lathes with faceplates 8-12 feet wide were set directly on the ground, with a large pit dug out to clear faceplate and...
http://www.knuth.de/produkt,10755.html It's a link for a heavy duty lathe, you may have a look to get some ideas for what you need. They are Chinese made but...
After further thought on the subject, using long pipe rollers is not necessary. (See previous post.) Rubber tired rollers would work. After I thought of that I...
I think that this type of work may be what they are trying to accomplish. http://www.riten.com/industries-served/roll-manufacturing-and-repair.html and this...
Hello everyone, sorry to delay answering but I didn´`t realize this method was available and just figured out how to join. The Metallisation video is the...
We have had a new transformer installed by the electric power company here, it took forever but it seems to be working okay. It is 220V 3phase 60Hz. One of my...
Hi, I may have said what we need incorrectly, sometimes I make mistakes, but the longest workpiece we need to turn would be 10 meters in length and 1.5 m in...
We have made overhead cranes to handle heavy pieces in our machine shop and thermal spraying areas and can certainly build more. As far as hydraulics, I think...
Yes, Bruce, the first link shows part of what we are trying to do. But we´re not in a country that has companies that can come out and do this work. We´re...
Hi Shannon, you´ve made a number of posts here and it took me a while to go through them, but my engineer Anibal says that the idea for the rubber tired...
Alexis, You gave the dimensions of the parts to be turned. How about the mass? Are these solid cast objects, welded rolled steel or something else? How ...
... I don't think so because the surface will be so hot that I think the rollers would degrade. That was why the head and tail stock. With that kind of load...
... Not a problem at this time. I am an "olde phart" who thinks better in feet. So 4 or 5 feet in diameter and 30 feet long (roughly.) Is this solid or cored...
... Your guys are right, 25 RPM is really fast. However a smaller shaft may be machined, and smaller means faster. Ask about a 1/3 meter shaft 3 meters long...
... Question, how difficult is getting asphalt on the ground outside the workspace (to limit dust)? How difficult would it be to put up tarps to keep outside...
... And contamination is an issue. Also how hot will the surface be? My guess is that the spray will make it very warm, maybe hot enough that the rollers...
... If you knew of another, it might be cheaper and less risky than making his own. A scrap 20 ton lathe might need a full rebuild, but it would be a good...
Hi David
 I have seen flat bed trailers , most of the ones I have seen have camber in them.
 The ones my friend had, has about 4 inch on hump up in it.

Hi Brian, The pieces would mostly be solid, thus the max load of 10 tons, those would not be as long, however, maybe up to 4-5 meters. The longer pieces mostly...
