I picked this up off a cool guy just south of Wyoming last night and spent all day today getting it running. It was made in W. Germany back in 85 but sounds like it just came out of the factory. If you don't know what a cold saw is think mitre saw for steel. It can cut perfect bevels in a fraction of the time a horizonal bandsaw takes to give you a rough cut.

My first test cut was on a 1.5" diameter alloy steel bar that took under 5 seconds and left a perfectly square end that was cool to the touch. Capacity on this one is 5 or so inches of steel.

what does the blade part look like?

Looks like a mitre saw blade, but it's like 14" diameter, made from solid carbide, and has fine teeth. It rotates at 50 or so RPM. Also is bathed with coolant. I first saw one of these at my local steel mill, but this one is nicer. The manufacturer is considered the best cold saw makers anywhere.

Oh, it's a Haberle ! Lucky man.

Ding ding! You are correct!

Ding ding! You are correct!

Although I am a custom woodworker, I sometimes stop by a couple of used machinery warehouses in the Cincinnati area just to browse. Lots of crazy old iron in that city. I would love to add a few thousand sf onto my shop as a metals shop at some point.

A lot of great iron came out of that part of the country back in the day. It's so sad we don't build any machinery here anymore.

Guess you have to have one of those to cut the raw stock to make gun barrels from :D. What else do you use it for? And when are you going to get that 40 in the background put back together?

Use it for cutting anything other than sheet steel, the CNC plasma takes care of that.

I'm almost done reassembling the CNC mill in my new shop. Then I'm going to turn out a hydraulic roller lifter cam for the 2F and concentrate on getting the 40 back together.

Now that would be way cool if you could make it work and keep it cost effective too. Wasn't the issue always that there was no source of pressurized oil to the lifter galleys to keep hydraulic lifters pumped up?

No, that's the easy part. I'm replacing the lower portion of the galley plate with a manifold. You just drill into the block above the oil filter to source the line.

The hard part for me was you need to make a cam blank from scratch and the distributor gear had me stumped, but I just got a new program that allowed me to generate the tool path to cut that helical gear. It does 8 passes with a very small endmill as a 4 axis job.
