Look on the bright side: that would still be $800+ cheaper than the nut off the shelf…

Here is a closeup of the Norton Diamond wheel. Because I am cheap. No, in all seriousness: the rectangular stones were very economical from Harbor Freight and it was going to be an experiment. They do not have them in the round format at HF that I could see. Here are the links for the...

I agree with your statement 100%, Don. I use the 3/4” shank version of those in my boring head on the mill very often. They work really well and leave a very good finish. Disclaimer: I did switch out the supplied inserts with ISCAR branded ones for better tool life and material compatibility (I...

For sure, his are top shelf quality and Robin-precision flat.

No, not taking orders. Sorry. I was in the US and bought them in person.

I’m in the wrong business. Maybe a retirement opportunity?

A little while back I bought two of these. They are the Asian knock-off of the Norton bench stones. Reviews say they are quite soft - I would agree with that. Are they flat? Well, when rubbing them together, they seem not too bad. Each one had some high spots and the reverse side had some...

Just updated my post above with local distributors. Maybe get a rack with a matching pinion. Slice off (turn down) the worn gear off your shaft and replace it with the new gear?

DP=(N+2)/OD; (14+2)/1.343”=11.913, rounded to 12DP. Your math is correct. I have some 12DP involute cutters; all are 14.5* pressure angle though. I would guess that in the 1990s they would have switched to the “new standard” of 20* pressure angle. BostonGear sells 12DP gear rack...

- using carbon paper to make duplicate copies - Gestetner Cyclograph machine for duplicating - cap guns and home made bows & arrows to play Cowboys and Indians - original pezz dispensers - going to the cigarette dispensing machine with $1 to buy an 80 cent pack for my dad (got to keep the 20...

Thanks all for contributing to a great event. Too many to list - so I won’t bother as I am sure I’ll forget someone. Unfortunately I did not get to show the dividing head as I (we all) got severely sidetracked… If there is demand, I can leave it set-up for a bit and demonstrate it on an...

Thanks for educating me on the proper name and function of “that thing in the corner” behind my late @Chipper5783. Much appreciate your pictures. Now I just have to find the missing parts for my Catheotometer…

Glad to be of help. For the ones that are concerned about alignment of a weldment: one can always turn a ”pin” on one part and a close fitting socket on the other. Chamfer each well (weld prep), stick them together and weld around the circumference. Turn down the excess weld and you should have...

How about a grade 8 bolt (or similar strength) welded onto any type of steel rod? As has been mentioned, it is the threads that take the most abrasion and thus lose form fastest. If they wear out, cut off the bolt and weld a new one on. You’d be back in business right away.

Places like that are beyond cool. Thanks for sharing.
