[Froneck]

Looking for a Jacobs 33 arbor to Moore Jig bore So as to use my tapping head in my Moore Jig Borer.

Post the jt dimensions, I have a few unknowns

I would be interested in taper 0 too have a like new Albrecht 1/4" chuck I think is a 0, have one for my Moore but another new one will be good to have. Then I will have to find my chuck as I'm sure I put it in a safe place!

My spare is a JT2.

I'll double check the heads, being they were very cheap I purchased 5 of them. One has the 35NMTB taper to fit my SPI quick change, another I installed a Morse #3. One is clearly marked Jacobs 33 but other 2 are not marked. The one with the quick change taper is made that way, no possibilty to remove it, all one piece with housing so it's possible others were made with different Jacobs tapers. I do have J6 but defiantly too big. However looking at the chart the J6 should almost want to start in a J33 being there is a chamfer on the end but don't. If I'm lucky the unmarked units are J2. I'll also check the one that has a #3 Morse, maybe it's J2, if it'd the only J2 I have I'll remove it, J33 to #3 Morse is easy to find!

Checked all the Tap drivers, they all are the same! Used a .610 gauge pin, It went in about 3/16". That eliminated all other possibilities. They all are definitely Jacobs 33
