Pinning a round object

[haldir]

So I've always have had problems pinning a round object, more or less trying to get the pin vise/drill into the round part of the piece. In this instance, the round part is the hand of the river troll 14008 (Warlord line). The wrist has a perfect indentation for the "ball" of the hand. With having to travel to play & such & of course actual gameplay I don't trust superglue alone.

 

Any tips?

Take a file and make a flat spot.  Then drill on the flat spot.

Thanks! I've tried to do a rough spot on the surface, so maybe I wasn't flattening it out enough.

 

Again, thanks for the advice.

I have that river troll, and what was suggested by @ttuckerman is how I pinned it.

 

If you ever need to keep the roundness (like a custom mace head that you need to attach to a handle), you can take the tip of your hobby knife, press and twist gently to get a notch started until your drillbit can bite into it. Just be careful that you don't slip and slice a finger on the hand that is holding said round object.

That's what I do. It's basically the same thing as a center punch.

My preferred, less hazardous, method is to score a small X on the ball and use where the lines cross as the point to drill. This also saves tje knife tip from the risk of breaking

To Everyone, thank you for the tips. Spaced doing this over the ccx weekend & did it this morning. 

 

Sanded the ball a bit, then X-ed it with a Xacto, then drilled. That hand is going no where!

 

Again, thanks!

Yeah, this is how I do rounded or balled bits.  I generally try to avoid flattening if I can so that the rest of the join retains as much surface area connection as possible.  Probably the difference is not an appreciable one, it just makes me feel more confident that it will hold.
