Shop Made Tools

[The Artful Bodger]

I just made one of these, but I can't get it any more accurate than >003" Can anyone help me, I am at wits end with that.

You may need to scrape the slider bit.

I recently found myself needing to apply straight knurls to a small part, my first need for knurling since selling my 3-in-1 machine. My square shank knurling tool went with the machine when I sold it but I still had a few stray knurling wheels hanging around. I was skeptical that a single wheel holder like this would work very well (or at all) but it actually works quite well.

I was fooling around with a finishing technique known as "snailing", on the two retaining screws. Needed something to practice on, so I figured it might as well be on something I use. I haven't exactly nailed the technique yet, but I've learned enough so I think I can get really nice results when I need it.

You can also do straight knurling on an edge with a spiral cut knurling wheel. Just rotate the bar holding the wheel so that the grooves are lined up with the lathe spindle axis. It works like helical gears work.

Nice looking parts, by the way.

Thanks very much!

One of my stalled out projects is an improved handwheel for an old shop made dividing head, and engraving graduations around the zero-able collar was really the only thing left to do to make it usable. Today I counted the teeth on my lathe's bull gear and wouldn't you know it ... there are 90 of them. The dividing head ratio is 120:1, so that works out pretty nice. I rigged up a little tool to index off the bull gear, and the only convenient spot I could find to mount it was the threaded hole for the rear spindle oiler. Sort of weird but it worked great. The little plate is A2 steel, the pillar and indexing pin are crummy hardware store steel, and the handle that slides through the top of the indexing pin is just a piece of music wire.

I'll add that the holes for the oilers are 1/4" x 32tpi, so I single pointed them.





And here it is in use, as well as the completed graduations around the collar:

Finally got around to making some step jaws for my vice



First time ever using a dovetail cutter

[quasi]

Nice work Corey, a slob like me just uses a hacksaw for corner relief!

[legendboy]

heh I thought about it but I have 5 dovetail cutters I have never used, when in rome as they say
Maybe I can make some bxa tool holders like paul posted above. that would also be extremely useful

Nice work Corey, and hope your'e nice mild weather comes back and stays for awhile!!

Shop made brazed carbide tooling - You cant buy quality brazed toolbits here anymore (Used to buy Sandvik, but no one here stocks those).

Made two flavors:
6x6mm square with fine grade carbide endmills brazed on and ground:




That one is for very fine work.

10x10mm Shank with a tougher carbide for roughing:


I machined the pocket for the carbide tilted at 5° so i get my clearance angle by default and only have to skim the carbide on the grinder. The carbide bits I use already have a angled side on them that creates the top rake - Also very little grinding needed there. Only thing that needs more attention is the front clearance angle and an optional corner facet or radius.

Safe angle grinder

To use it safely, I fastened my angle grinder to a plywood board using a metal Ω (omega shaped) 2 inch metal bracket, and a single bolt through the board. The metal rod I want to cut is placed on a v-grooved board and fastened using three socket head screws. After cutting, and with the switch depressed, the board with the grinder pop up due to a spring located at the base. Disassembling is quick, and the hand-held grinder is there again.
