Any special way you pin??

[james9487]

I have been pinning a lot lately, and I have come across some mild problems. When drilling a deep hole in, lets say, the arm and the body section where you glue it on to, do you find it hard to match the holes perfectly? What I mean is a lot of the time the two holes don\'t exactly match up, so when you place the pin in to hold the parts together, the arm shifts in a direction (other than where it is supposed to!) and it doesn\'t look good. By that time it\'s extremely hard to drill two more holes because well, it just is. Is there some kind of a trick or something? If so, please educate me. Thanks,

I usually just go about making one hole bigger, and then use two-part epoxy instead of superglue to do the gluing. Yeah, I pin a lot too, but have found no special tricks other than to take care right from the start.

One trick that works fairly well is to make a pin just a little longer than the hole. Put it in the hole without gluing. Put a touch of paint on the end of the pin and hold it where it should go on the piece it is to be mated to. Once happy with the position simply move the piece with the pin toward the other and touch it with the pin. This should leave a small dot where the hole should go. Replace the short pin with one the appropriate length and there you go!! Good luck.

Well I have yet to actually pin arms to the body. I would think that I would have to drill one hole and then place the pin in with a bit of paint on the tip to mark the other hole and line it up that way. I hope that this helps. I am sure that there may be other way\'s out there, but this was the one that came to mind.

Edit: Well it looks like I was beaten to the punch. But on a positive side my idea looks like it could be used.

Thanks for the replies. The paint on the tip of the pin sounds like a good idea.

If the parts line up tightly and the parts are beefy enough I drill right through from the outside and cap the hole, once pined and glued, with a bit of green stuff. Makes for a super tight and strong joint

The paint trick is good.

But it only works well on joints that are well-mated and it is fairly obvious where the second hole should go. In more difficult cases I cut the pin (again only slightly longer than the hole - this is also a \'waste pin\') at a sharp angle with side cutters. I then place it in the hole I have pre-drilled and fit the two pieces together twisting slightly until I can feel a good fit. When you separate the components it is normally pretty obvious where you need to drill as the sharpened end of the waste-pin has almost started the task for you.

An even better, and more secure method, is to drill completely through the smaller component and then place it in the desired position. Then fit your drill through the existing hole and drill into the main body. All one needs to do then is apply some glue, push a length of wire through the two components and let it set. You can then cut off the protruding wire flush with the model using some side cutters. A quick touch up job with a needle file and Bob\'s your Uncle!!

EDIT: Bugger! Garyo hadn\'t posted when I put this up, now it looks like I am stealing his idea

Very carefully....

No really- sometimes I\'ll use a paper clip for odd angle pins since it\'s easy to set one side and then bend the pin into the shape necessary for the second piece.

drill 2 holes insert pin (i go as deep as possible without hurting the poor baby :innocent

another way is to flare the holes a bit.

then if the holes are off a bit you can bend the pin slightly to make up for it
