We all come up with our own versions. One of my pet peeves...I HATE MAGNETIC INDICATOR HOLDERS. So here are a few homemade dillies I made up. They cost nearly nothing, and work quite well. The first is a tool post mount on my SB 9" I used the articulating arm from a magnetic base, and cobbled it together.

Here's one on the Grizz...It fits in a .500 collet, or a drill chuck.

I was forced to modify the downfeed handles on a Delta drill press...Yes, I forced myself because I wasn't happy with the origional. Here is the before shot.

And here it is after. If you read my earlier post about drilling ball bearings, here is the end result. Instead of trying to drill and tap, I used my MM251 to tack weld nuts to the balls. Quick and painless.

Now let's see some of your gadgets!

Here is the tap guide that I built last winter.

Ewan...I like your tap guide. But one question: How do you keep the taps from spinning in the drill chuck?? Or do you just get enough threads started to be sure the rest will go straight?????

Wheat:

I normally use a milwaukee drill to tap holes.

Usually it is sheetmetal, A good VSR drill and you can tap easily without breaking taps.. really thick metal is not so easy.

When I am building back panels for mounting devices in a control panel I get the drill hot tapping holes.. I run it without a load and cool it down. Sometimes I hit the trigger and push the hold button. I have a drill I bought 24 years ago that still works great, the chuck is wore out now thou and it slips on the taps.

For large taps (3/8" and up) I use it just to get the tap started straight. Smaller taps don't slip in the chuck.

IBEW:
I too used a Milwaukee for tapping holes for control panels. Usually 8-32 but occasionally as small as 4-40. Before I began doing my own machining, I would design a fixture and give it to a machine shop to build. Most of the places I dealt with were uncomfortable tapping any holes much smaller than 1/4-20. They regarded a 4-40 as extremely difficult and were astonished when I would do it for them, sometimes with the Milwaukee hole shooter.

Here is fixture I made to cut small gears on my lathe. I have no mill yet so I devised this for temporary work. It is held in a milling vise and I use it with a cutter held on a mandrel between centers.

Arbo:

From the "great minds think alike" department, I have several older indicators, lever type, and ALL came with a toolpost holder like the first picture.

Clearly you are on the right path!

Now, if only we were back 100 years ago, neat ideas like that for machining could be the basis of a new company.

BTW, why on earth would "great minds think alike"? You would expect them to have some originality and differing views if they were so great....unless there truly is only one answer.....

I have seen (but don't own) a small 4 jaw Jacobs chuck. How handy would that be!

Arbo, my pet peeve is vises that get in the way so I made this "gadget", it is an under the bench mounted vise. The slot allows adjustment in and out and I mounted it under my regular bench vise so they could be used together for holding small items to be soldered or brazed. I also made easy adjustment "wing nuts" out of nuts with flat stock welded on. Scott.

That was exactly what I was thinking as I read this post.

Wahlstrom automatic keyless chucks have 4 jaws.

Very expensive, but can be had cheap used.

Once you get used to them they are really fast.
