New Machine Tool day! Have you seen these tools before?

The circle cutter actually works pretty well, but the fore/aft adjustment is critical. The point has to be right at or very slightly ahead of the blade teeth. Also on my DoAll I use the on/off as a master power switch for the saw but I added a foot switch for the blade. I figured that if something goes bad with the saw I didn’t want to try to get out of the blade and over to the switch. Something happens, I step back, blade stops.

Steve, in the late ‘70’s I worked in a pre-CNC machine shop. My friend worked as a tool and die maker and so he operated one of the SFM-type grinders. Our company used some extremely heavy-duty multi-spindle turret machines like Wickmans. He routinely would precision-grind tools with machines such as these. I remember him using the profile viewer as well. Cool tool indeed!

Seeing Cora enjoying herself made me smile. Lost my shop buddy this week

Amazing tool that I didnt know I wanted. Al comes through again. Bet even Stan was envious.

Holy Cow! that must have been one expensive tool in it's day. Nice addition for they guy who does not mind making his own tools. Outstanding Steve.

Steve I love your shop videos, but ive absolutely feel for your dog Cora, shes a real sweetheart and reminds me how much I miss my dog Lady, one of the best dogs that ever lived. Cora seems like such a well behaved good natured pup, Id love to have one just like her

Truely skilled men that designed and made those machines.

That grinder performance is jaw-dropping. Amazing machine.

First thing that came to mind seeing that was rifling broach fluting. That built in optical comparator is the neatest thing since sliced bread on a shop tool. It's really a tool station. Good investment

That RO grinder was really something! Your demonstration spin-up of the grinding wheels to tens of thousands of RPM was amazing. Sort of like DARPA testing a new kinetic energy weapon.

When I saw how much those balancing stands cost, I went in another direction. I bought an accelerometer sensor ($5) for an Arduino microcontroller and was able to dynamically balance it. I made a plate so I could add weights around the perimeter and moved them until the vibrations were reduced as much as possible. It really improved the surface quality of my ground finishes.

As an apprentice I had the opertunity to use a machine similar to this. Was very satisfying to use to turn a tray of dull drills and end mills back into usefull tools.

Spent many hours running one of those !

I like a man with so many machines that he has to use a stick to reach the on/off switch of some of them!

Christmas day makes a return! New machine tool day yippee! Good morning from the UK Cambridgeshire fens on a cloudy day!

Great shop also like the square body in the back round .

That’s a very fancy grinding machine, I think you will enjoy learning to use it to it’s full potential. Good girl Cora. 👍

"Steve Gets a New Toy!" 👍🏻😁🤣

Nice new tools! Thanks for sharing.

Hi Steve, as an amateur machinist I was so relieved to see how you balanced those grinding wheels. I made a balancing jig that works on the same principle as your commercial one and used it mainly on those horribly unbalanced wire wheels with excellent results. As there isn’t much to dill on a wire wheel I would add self tapping screws to the light side to even it up. What a difference that makes. Anyway I used the same jig to balance the wheel on my surface grinder and like you I drilled the stone to balance it. I thought it was probably a very shoddy way of doing it but I feel a whole lot better about it now. That grinder is an amazing piece of kit and I shudder to think what it cost new but I’m sure neither you or I could afford one. I love those Do-All accessories. Cheers Stuart 🇦🇺
