New Tool Day: *HEAVILY* tricked out Mori MS850

[Alberic]

I sometimes sit in a rolling chair when doing long face milling...with a custom made .250 thick lexan shield between me and the spinny thing

There were all kinds of guards of various sorts. They all got set to the side, and moved in a batch, by themselves, so it's hard to figure which ones went with what, but there may well have been one for the Bridgeport chair setup. I'm pretty sure there were one or two for the Mori that I never ID'd.

FWIW,
Brian

I knew the owner of the Mori and other tools. I installed his phase converter and connected the Mori. It has a NEMA D motor and no clutch so it is started and stopped regularly. It requires an over-sized phase converter.

Yes, Roger was short and slightly built. He was extraordinarily talented. He raced motorcycles at the old Hayward TT track, a very short tight dirt track with multiple turns and a jump. He served in Viet Nam as a welder but got interested in machining and hung around that shop and learned everything he could. When he returned to the States he parlayed that experience into a machinist job for Hewlett Packard, that became Agilent and then Keysight Technology. As the OP noted, he was the lead/foreman machinist.

He could imagine and make almost anything. He built a mechanical variable stroke attachment for his KO Lee hand surface grinder, converted another KO Lee to a cam grinder for model IC engines, and converted his Clausing 13" lathe from hydraulic shift varispeed to 3 ph VFD which I wired. He also did gunsmith machining for a local gunsmith.

Last I have heard is that he is in hospice.

Thanks Carl/Lathehand for the very nice description of a outstanding man.

I have an interest in both electronics & machining and I admire the work in both fields done by HP in what I call the "electro-mechanical" era, when both elements were taken to a very high standard.

In my little "museum" of artefacts that interest me is a HP 536A frequency meter; in pre-digital days, these relied for accuracy on a very precisely-machined piston & cavity.







No doubt this man would have been involved in this precision-machining project.

"A simple swing down support that just clears the floor when not seated would take up all the weight and the connecting links would just position the stool so little or no load on the machine. "

True enough. Then, once you had the simple down support in place, you could remove the arm that attaches to the mill. This fixture would then provide full vertical support but also allow for movement in any horizontal direction. This is the sort of spitballing that produces great inventions, not just good ones. I've piggybacked on the Mill-Chair idea and come up with what I believe is a device that will revolutionize milling operations. I've already applied for the patent, so I don't mind posting a pic of the prototype. Feast your eyes, boys!

This is entry-level German.

Advanced level German it would be stainless and incorporate more obscure mechanical devises.

The compound tray is probably a beer holder.

Man I never knew a chair on a guys personal machine would upset so many people... machinists.

The problem for me isn't the chair, it's the way it's mounted. You guys admiring that really think that won't apply any side forces to the screw? Which won't apply any to the table/knee? Not on my machine. I'll stick with GregSY's novel invention.

There was a line of shop stools made just like that, with a drop foot.

Yup, I really think it won't make a significant difference at all. The mounting ring is way down at the bottom of the support casting and unless the sitter is bouncing around while cutting (really gotta go, or something) its a non-issue. Some of us are so small we have to run around in the shower to get wet. For you 'man-size' men I suppose it might be different.

Being my luck, I'd go to sit down and flip the BP on it's side with me on it!!!! I'm quite happy with my high back Craftsman swivel chair with a busted foot on it! I just have to be careful on moving it around. Damn Chinese crap!

I'm amazed by all of the neat things this guy made for his machines. I find myself making similar "things" for use on my machines I have, too.

Not when the knee is locked. Anyway, it was his personal machine with his personal solution to a problem. I would expect that he tested whether sitting on the chair did anything, with a tenths indicator, I know I would have. Just part of knowing your machine.

Yeah, I am pushing 220, and just getting on and off tha seat would flex things pretty good I am sure - that's cantilevered way out. But nah, not for me regardless. I've seen the difference even tightening the lock to different levels can make. Not many machines I've run across are in pristine, fresh-scraped condition. Goes back to the "everything is made of rubber" bit for me. A support foot under that seat would be a very good idea IMO.

That chair reminds me of Abom making a skyhook mount for his toolholder on the lathe. People on the gram just flipped, its like dude calculate the forced of .5" DOC cut you idiots. This stuff is also why people who can't calculate shit make everything out of 1/2" plate steel.

1/2" is kinda skimpy, don'tcha think ?

 

[Tyrone Shoelaces]

For sure. Some people would complain if they were hung with a new rope. Never just let it go, always finding fault.

I only got hit once with a job. I was rushing to complete a smallish counter bore on a pillar drill. Instead of clamping the job down I held it with my left hand. Mistakes I have made. Drill snatched, spun the job around, broke the drill and then the job was thrown at me. It hurt but not as much as if I’d have been sat down.

Regards Tyrone.

This is Practical Machinist.

I swear, the drill press is the most dangerous machine in the shop. We all do that stuff, and we all know better

I guess this is the point where I mention that yes, of course there's a tool post mounted skyhook for the Mori. I didn't bother mentioning it because I've seen that particular trick so many times before. Even had one myself, on a past mori-clone. Looks like the company that makes the skyhooks actually makes CXA mounts specifically.

Now make a CXA chair mount.

Just the other day I was trying to drill out a copper fitting...attached to a 18-24 inch piece of 3/8 wire...holding it by hand. Of course it wrapped up and I accidently put it in reverse and got whipped a few times before it wrapped back up...ouch lol

I think that comes down to the cantilever again. The cutting tool in normal use on a lathe is not far outside the ways. A 100 pound chuck lift usually would be. It's called leverage. There's a lot more than 100 pounds of force applied to the compound when using one of those. Same goes with a long boring bar. Say on a certain sized lathe you might be able to take ½" DOC tucked up tight to the compound, but that same machine won't like ½" DOC with a long boring bar that's cantilevered out far from the compound. But you do what you like with yours, I'll do the same. All good.
