Or deep space probes, system defense batteries, cosmic listening posts, what have you. I was always amazed at these things in the ancient long ago and am glad to see some preserved!

Thinning the ends of tubes, engine bells, etc.

For years I've used various sizes of countersinks to thin round open ended parts, especially engine bells. For a current project I needed to thin the open end of a thick plastic tube. I only have a 90 degree countersink in that size, and the end still looked too thick. So I broke out the step bit se...

Conductors punches

Yes, yes and yes. But for your application you don't really need music wire. What size drill are you using? Ordinary straight pins are about the same size as a #70 drill bit, can be cut with nippers, and when chucked into a Dremel will nicely bore their own hole. For some more variety, use paper cli...

Are you just drilling in and cutting them off for antenna? If so. just use wire chucked into the drill- it will bore into styrene just fine, and is easy to cut.

I use 60 year old decals all the time- sunlight will bleach out any yellow carrier, and a light spray of Krylon Crystal Clear over the sheet will keep them together- just cut the individual pieces apart before soaking. Soak 'em, Slide 'em, Stick 'em as the Jaco-Lac sheets say.

Those are a lot tougher than the silicon carbide cutting disks, but cut a wide and messy kerf. After learning patience I really like the brittle carbide disks better. Any side load and they will disintegrate on you, but make a nice cut.

That is nasty! One thing that will work is to fill holes like that with baking soda and then solidify it with crazy glue. You can flatten and do some shaping of the powder as you are packing it in. I've never had problems with this method-I have one model that's 10 or 11 years old and is still solid.
