HELP! thread gage removal

[TheInspector]

I've been given the task of calibrating some of the Thread Gages at the shop where I work. I'm having trouble trying to remove the GO thread from a double-sided thread gage (pic1).
Normally on this type of handle, the tapered end of a special drift-punch (pic2) is used to remove the GO thread, then the reverse side of the punch us used for removal of th NO-GO thread.
My problem is that the back end of the GO thread doesn't extend into the handle far enough for the drift punch to hit it (pic3). Any suggestions?

Thanks in advance,

TheInspector​

Drop a small ball bearing in through the side hole to take up the distance,* insert drift and hit

*A little grease will hold it in place.

+1 on the BB. Used that trick a number of times. It will sit in the grinding center on the gage member ok with a spot of grease.

Same thing I'd suggest x2

The handle is aluminum. Dip it in 300 degree F hot oil. Expansion of alum Vs Steel will release the plug.

Before I learned of the BB trick, I just set them under an incandescent light for a while.

Forrest's hot oil reminded me. Hot oil would certainly be quicker.

suggestions on type of grease? we have about 50 different types here. (or does it even matter, as long as it's semi-sticky?

 

[Tony Wells]

The grease is entirely uncritical except for it's sticktion.

A brief visit with a torch, I use that to remove collets from my little mill, works every time...I keep a Benzomatic handy for that purpose.

sticktion

The grease is entirely uncritical except for it's sticktion.

Sticktion is a word now. we should all add it to Wikipedia as follows:
sticktion (adj); the ability of a given product to make something stick.

see also: coefficient of friction​

 

[Tony Wells]

Opposite of lubricity, maybe? Or would it be Teflonicity?

Solution

so, i was unable to find a ball-bearing of the proper size that I could pound on, but I cut the short end of an allen wrench down and used it in a similar way. no time for pics, sorry.
thanks for the suggestions, guys.

insufficient

sweet coincidence, but the existing definition is insufficient.
we all need to add an additional one.

 

[Tony Wells]

Slightly different word. Static + friction is stiction. It's more fun to make a new one for grease. Anyway.....don't get too serious here.

Inspector...you got the late shift, eh? Glad you found something that worked.
