Dan,

I like the idea of making a tap to do the threading. Seems way easier than cutting internal threads over and over! Also, thank you for the link. I'm trying to figure out all this stuff without any experience or hands on is difficult for me!

Manny,

I saw those. good price for sure. do they need to be sharpened repeatedly?

Lewis,

Note that the minimum bore for the LMS tool is 1/2".

As far as sharpening goes, It's HSS after all: Your mileage will vary.

Bill,

Good to know! I wish you were closer to Ohio. Are you going to MPG?

Default Making your own specialty taps. Bock 5mm

Dan,

You referenced your thread with the above title which I read.

I must be missing something. . How does 0.253" relate to 5 mm ?

I calc that 5 mm would be 0.197"

Mal he is referring to the nib size which has a bigger housing thus the bigger thread. Have a look at the writing on the taps Beaufort sell for the Bock housings and it will make sense.

Thread taps for Bock nibs

Well ... OK, Pete ... I have had one quick read and I still don't get it.

One thing I did get, though, is that Beaufort uses "plug" to mean "bottoming".

Seems to me that "we" use "plug" to mean "intermediate". . Or am I screwed up ?

"Two countries separated by a common language" George Bernard Shaw.

We are a UK based company, therefore we use the UK nomenclature, however, we do put the translation there for you colonials too

What you call a bottoming tap, we call a plug tap. What you call a plug tap, we call an intermediate tap. We also put the pictures there for the avoidance of doubt.

I happen to think that bottoming is a much better name by the way, but don't let on I said so. I don't want to upset the natives on this side of the water.

I meant a Bock #5 nib and feed. Not 5mm. Sorry for the confusion. It is a strange thread size to use. It seem to be a poor mashup of 1/4" thread with a Metric 0.6mm pitch. Easy enough to re-create on a metal lathe but expensive to have made. I used these homemade taps for a handful of kitless pens, and they work quite well for aluminum, brass, and acrylics. They worked ok with stainless steel. I thread on the lathe with a tap guide in the tailstock to keep everything straight.

I've since joined in on the last group buy and purchased a set of plug taps for #5 & #6 JOWO and Bock feeds as well as some triple start tap and dies.

Making my own taps taught me how to thread on the lathe and got me into making kitless pens a year sooner than had I waited for the Group Buy. After threading on the lathe for a while I switched to taps and dies with the tailstock holders and guides. They are SOOOO much easier and quicker to use. The finish of the threads are also better and the mistakes are much fewer.

There is a great satisfaction in making your own tools too especially when starting out on a budget.

Danny
