The proverbial brick shithouse is alive and well. All 3200 lbs of it. It is setup for ID and OD grinding. What was supposed to be a cam grinder was actually a pair of bench centers with a chuck on one end. It could actually make a nice cam grinder with some work.

Does it need a plank wedged in some where just right to get it spot on and its handling? Turbo profile is not same as belt driven need.
 
Nice. Would a tool like that clean up the slider bore wear in my stanchions? Brilliant guy in that video.

No, A lathe, a reamer and a hone would be best for that. Jim
 
Ugh ya mean not a long dowel with sand paper wrap on a hand drill? I do notice the good lighting in the climate controlled mice dropping free interior, cool.
 
Nice. Just add a couple servos, a few circuit boards, write some software, and you're in business. Shouldn't take more than a weekend, right?

Hi comnoz.
I can appreciate your excitement at the acquisition of new equipment. My query relates to the appropriateness of the thread line chosen in all the excitement. My lack of verbosity in my query may appear undiplomatic even harsh to the more delicate amongst us but rest assured that the sentiment is benign although I do still consider the point a valid one. :D <- sensitive & caring smiley face.

Hi Jim
That looks like a good buy, and as Ken suggests CNC control would allow you to make many more parts for NORTON COMMANDOS, looks very ridged.
Also it looks like there have been some modifications already ie, an extra internal spindle, and what looks like a drive to the X axis, (longitudinal)?

Best Regards
Burgs

Some CNC control would be nice . Maybe someday.

The ID spindle was obviously added later. It is far from new -but younger than the rest of the machine. It has a date of 1968 on the motor and bolts to factory mounting holes.

The feed motor is for the Y axis. It was original equipment when I got it but I had to replace the fried motor. It was originally a 2 speed motor with a 3 step pulley. I replaced it with a variable speed DC gearmotor.
It has a microswitch sensor and a pin that flips out to stop the Y travel at a preset position.

The first job will be modifying a batch of Harley starter armatures to fit in the CNW starters. I used to do them with a carbide bit in the CNC machine but getting a proper bearing fit was a tedious process. This machine makes it easy. Jim
 
Well the grinder worked great on the armatures. They finished within 1/10 of a thou easily. No more stopping when they were still too large and then carefully working them down to size.

You showed me yours so I'll show you mine. It is a 1963 Haro H2y made in Switzerland. It was purchased new by Boeing Aircraft in Seattle and appears to have been ordered with every conceivable option and attachment.
It has power rise and fall on the grinder head and the vertical lead screw has been damaged due to a failed microswitch.
Other than that, it is said to be in very good order. I bought it to use as a surface grinder, but it is capable of much more than that. How much more, I'm not really sure. Jim probably has a good idea. It has hydraulic stroking for surface grinding.

That looks like you could grind about anything you could imagine.
And a fun project that should keep you busy for a week or two.
 
Apparently this is what it will look like when all reassembled and cleaned up

A friend found it and was going to haul it for me on his single axle bike /cargo trailer, rated for 1400 pounds payload. The shop manager thought it weighed around1200 lbs , so they were going to load it, except my friend was unsure if we had 440 volt three phase needed to run it, so he held off.
We do have that voltage in the shop so he and I went in the next day with the 14,000 lb stock trailer. When the grinder was loaded on the back of trailer, just before it was pushed forward over the axles, it nearly picked the rear end of my 1 ton SuperDuty off the ground!
On looking at the manual, it turns out the machine weighs 1860 kgs with attachments. Good thing they didn't drop it in the light trailer.

Glen, did you get that from Boeing Surplus? That is a great place...

No, I bought it from a smaller shop. They had purchased the grinder from Boeing Surplus a few years ago. Their business has changed a lot and they no longer need a grinder.
