Well here it is:

Tang buckle on the strap.

Back side of buckle. The leather end of the strap has been pushed down a bit to show the end of the pin.

The special tool with the “U” shaped end engages the pin on its collar an pushes it down disengaging it from the hole in the buckle.
Always do this on the back side so that if the tool slips it may mar the back of the strap rather than the front.

The pin disengaged showing the end and the collar. You can see the hole in the lug just to the left of the pin.

The pin can be seen passing through the strap end.

Here’s everything out. If you don’t have a separate pin for the deployant you can use the one for the tang buckle
since they are identical or very close.

The deployant laid out with the strap and prefitted and properly oriented. Make sure you don’t put in on upside-down.
Also check to make sure the end of the strap and deployant are the same width (ie 16mm).

The pin is placed in the strap and pushed down so that it protrudes out of the strap as shown. Doing this helps seat
the pin in one hole of the buckle (deployant or tang).

The bottom part of the pin is seated and now I am pushing down on the collar the top part of the pin to bring it under the lug.

The pin is under the lug. It's difficult to see since my finger is pushing down on the lug to hold it in place.

Sometimes the pin will pop right in the hole. Here it is under the lug but not yet engaged in the hole. Carefully and slowly move the pin and/or lug until it drops into the hole. Make a mental note of where the hole is in the lug’s underside so that you can more easily move the pin into it. But even at the best of times, the pin will pop out the other side of the lug and you have to try again.
Pin engaged!

I prefer those types without question. Soooooo much easier to use. I have not seen that tool but it's a very clever idea. BTW I looked at kits in the Bergeon catalogue. There's a really great one that has everything including a high price (about $1000 !!) Regards, Joseph
Thank you Joseph

I had a Bergeon tool but snapped the end off (don't ask)... Guess I better just go get me another! But what make are you using there? Cheers again Gary
It's also a bergeon, Gary

You can't tell from the photo but one side of the "U" is missing a little piece. It still works though. :-) Best, Joseph
