Anyone know what these old lathe tools are?

I bought these like 8-10years ago as a "lot", since I wanted a set of carbide reamers what was part of the lot. I actually had forgotten I had these until this weekend when I was looking for a piece of leaded steel for the gas check seating die I was making. Anyone know what these are for?

These look like some sort of knurler:

This one I don't know:

Another one:

A variation on the one above? (20H vs 20HA)?

20B I think ...

They're all variations of adjustable knurling tool holders. Most are missing the knurlers themselves.

My old B&S catalogue agrees that they are "knurliers and flutters", but I don't know the difference. They are listed prior to 1940.

Wow. I would love to have photos of those catalog pages, please???

I had no idea these were that old, specially since the fitment and finish on some areas are superb - all done prior to CNC machines I suppose.

Just a FYI type question Will; what coolant do you run on your Mill. I'm thinking a Mister would be ideal for my needs.

Gary,

I have played with/experimented with 3x different systems in the last 10+ years:
- kool mist

- Accu-Lube micro mister:

- Traditional flood coolant (what I use today)


Each one has plus/minuses. Kool mist works well enough for basic needs and it is a good place to start. Nothing wrong with that route.

The mister was not as good as the Accu-Lube, which was also the least messy and most advanced (hands-down). But the Accu-Lube is terribly expensive, a little complex with many parts/adjustments, and not quite as effective on Titanium.

For years I resisted traditional flood for the mess, but once I found the Accu-Lube not good enough with Titanium, I converted fully to the flood coolant and have not looked back - ever. It is (for me) the best thing I have ever tried on the lathe. Some of my insert tools seem to last forever :)

Thanks, Will. For my 7x14 I'm going to add a Kool Mist system soon, especially for drilling and boring. Just using brushed curting oil, parts get hot enough with multiple passes to change dimension enough to casue problems. Chip removal is also a constant nag.

Flood coolant is the way to go no doubt, but I want something that's cheap, easy, clean, and can be left unattended for weeks or months in a very hot shop without spoiling.

Ordered the Kool Mist fluid. Already have a cheapo mister setup and I'll change it out if it doesn't work very well. Ian, I see the Tikka made it to San Antonio and should be at your dealer tomorrow.

May sound funny but get an old fire extinguisher tank and valve at your local junk yard. Drill a couple holes for some small eye bolts,then a small hole for 1/8" pipe fittings and install a small compression valve as a vent. Where the regular valve goes just bush it down so you can use a small valve and a piece of copper tubing. Hang it from the ceiling sort of like an IV bottle,but leave it so's it can be taken down and refilled. Gravity does the work and just crack open the vent valve to maintain a flow. But if and when you decide to do this,first clean all the crud out of the tank. Most fire extinguisher bottles I've seen were for dry chemicals. Some liquid Dawn and hot water should clean it out and rinse a few times. Frank
