5/8-16 Tap

SPiN Racing:
Ok sooooo

I bought a Arbor for the Peck drill. It has a 5/8-16 Thread. (So the box Says)

I checked my local too place and it was a big Zilch. Nothing. Nada. No 5/8-16 Taps.

SO then I checked John's (Bogs) place there across the pond... and nada.

Am I looking for something odd here? Or something that doesnt exist and was a Mis-print on the label?

Its an arbor that is used for chucks.. but.. I cant find a tap.


Suggestions of places before I toss caution to the wind and try some random place on the Intarwebs?

Thanks a bunch!
Scott


PS: I dont expect some goodle search of it.. cause I will do that.. I just thought if there were other places you all go to and trust.. I would just as soon go there online, verses rolling the dice with someplace.

Spin,

That size does not exist, it might do, but not in the standard range of thread sizes. Maybe it is a standard for chuck manufacturers.

I am wondering why you are going the long way around for a peck drilling attachment. See C-o-C.

Just a smaller version of this

This is what a pin chuck looks like

Im sorry.. I guess the two projects Im working with at once were bound to get things muddles for everyone, as well!  (I got confused when looking through supplies trying tog et things clear in my brain yesterday)

Im making a Peck drill... AND.. a Tapping thing.  But two different projects.  :D

The Peck Drill Im making is using a 1.75" piece of SOme form of hard Stainless. THe stuff used for race boats with a inboard engine. I guess the scrap yard got the shafts from someone who crashed well enough that the shafts are fine.. but the rest of the boats were write offs. Or they were spares.. WHo knows.

Anyhow.. I have the 1.75 Stainless that I am making a peck drill similar to Ralphs, but a bit bigger with a larger chuck, so I can drill larger holes.. but not get carried away.. I like my arm attached.. and a large drill bit biting, and slamming a peck drill lever into my chest isnt one of the things I would like to achieve with my Lathe.

So yes.. Peck Drill.
1.75 Stainless rod. Drilled the hole in front, need to turn a taper for the chuck still (Looked at your how to John, and plan on going that route) and drilled a starter hole in back of the rod. Now I just need to get a tap at that size... that doesnt seem to be readily available. But some googling around and yes.. that size is available. (67.50Pounds +VAT special order from one place)

The tap is for the Arbor I have. Its nice and beefy.. but Im not sure if its overkill, or just silliness.

I am going to contact the local bolt and screw place near me that usually has a nice selection of things... will have to wait and see.

John Stevenson:
It does exist.

Yeh; instead of saying something doesn't exist, it would be beter to say, "I'm not aware of any".
Here's another source, but it'll cost you $15.
