Default Mini Tapper

Here is the mini tapper I just completed based on plans available online.
Plans call for 3/4" aluminum base 4x6", I used a 1/2" CRS 6x6" base with materials available from local metal monger. Unit works great for #2 and below sized taps.

Default Mini Tapper Plans

Believe I found the Plans in the Download section. Page 1 of the 2 pages of drawings indicate they were provided from "Open Source Tools".

Very nice! Looks like it could handle larger taps than #2.

Have you considered any sort of finish for the CRS! That is rust prevention. Ive been using tool black on some of my stuff. The trouble with tool black is that the protection is minimal.

Here is a very old post of mine that shows a little jig you could make for your tapper, perfect for getting things square to an original hole.

I've never seen such a thing but it's a great idea. Thanks John!

Thank you Al.

This was from the days I was making batches of the same steam engine, and without it, it would have taken many more hours to achieve what I wanted to do.

I just showed the item without the expanation and it fooled everyone, it was only when I showed the second picture that the light bulb was turned on.

With little jigs like this, if you are doing a lot of tapping, it can make life a lot easier.

I have dozens of little things like this I have made over the years, they really do make things simpler, and well worth the time to make them.

My shop has very little moisture issues, never experienced any tool rusting. Have large Dehumidifier that does a great job of controlling % humidity, which is currently at 30% RH. During the hot summer muggies here I usually capture about 2 gal/day of moisture, fall & winter much less and during very dry periods the DH never even comes on. DH devices are worth the investment to keep your tooling shinny.
Given my current moisture control I probably won't coat the tapper with anything beyond a light coat of oil yearly.
