I used double sided tape 3m

Depends on the mod and location but zip ties and dble sided tape are good.

Thinking about adding some figures to one of my pins as well. I know this has been mentioned in another thread, but it would be fantastic if Pinside had a section under each game to show off mods!

Just do what Stern does with most of their newer pins use "Zip Ties"

I've begun to use some of the tapes they advertise for hanging stuff ... you know the ads where it peels off easy with a tug but holds good.

I used double sided tape 3m ...

I think this is the best way to go. They make a clear tape that is quite strong. It's perfect for this type of application.

If your damage your mod piece or change your mind you want something you can get off without damage .. don't glue it imho. Use something that can be removed even if you need a little alcohol and elbow grease to take it back off. All the suggestions are great about tapes and ties.

EXCELLENT QUESTION!

I bought alot of miniature Star Trek ships from amazon.com and have been putting off installing them
in my pin.

I was thinking about using zip ties, I have small white ones, just been wondering how well I can conceal
them, which is going to be impossible, and still have them look good at the same time. Guess I'm
going to have to take the plunge and just do it and find out.

There was a pinsider, Fretlord, who had a ST pin exactly like mine for sale on Ebay during the timeframe
I was looking to buy mine. He had two versions of the Enterprise, ship mods, that he installed on his.

I sent him an email through ebay and asked him where he got his ships. He responded and I found the
exact ships, once again on amazon. Bought them, and they are snap together, and have ship decals
that have to be soaked in water, then applied. Those decals are a pain to deal with. Like the old school models
from the 70's style decals. The other sets of ships I bought were made by Micro Machines, no decals required.

Long story short... I gotta get those ships installed and see how they look.

Museum putty is another option. zip ties will certainly work but not a "clean looking" option IMO.

U-Glu works great and it is what I used to mount figures on my LOTR LE, TSPP, and IM. It holds very well but is still easy to remove with no trace of residue whatsoever.
