Hello
Sorry, if this sounds kind of dumb but I wasn't sure what to search. I am running some leads from caps,resistors, etc and I noticed on a lot of other builds that guys will cover/insulate them with cloth, tubing etc. if they have long runs. I can't believe that they're just stripping from excess wire that they already have so wasn't sure if there was something you could buy in general to cover over bare leads/wire. Im aware of heat shrink but was thinking of some other tubing/cloth.
Im guessing as well, if build is arranged correctly, there isn't a need for this because everthing will kept short but I am not in that boat right now.
Thanks

If you're gonna "fly" leads around in the chassis then they should be insulated. I cut the component lead short, solder my wire to it then shrink-tube that connection.

Old folks called it spaghetti. Teflon tubing is more modern and much better. Everybody should have several sizes. 22AWG is what I use mostly.

Here's a pic showing some I used on a recent project. Look at the two pots next to the input jack in this pic (upper right)...

Sometimes I use solid-core wire I have on hand for buss-wire duty. In such cases, I wind up with a lot of excess insulation sitting around. If I'm inclined to insulate a component lead, I do just re-use the otherwise waste insulation.
But Sluckey is right that the old stuff is called "spaghetti" and that you can buy tubing of various materials for the purpose.

That's exactly what I was looking for/thinking about.
Thank you.

Another useful product is teflon/tefzel/ptfe spriral wrap. Look on eBay or in closeout bins of aircraft websites like AircraftSpruce.com.
This stuff lets you pop out a wire from a bundle at any spot, nice for pot wiring.

I miss it, I've seen only images of the inside (or I didn't remember I've seen and this will be more serious (http://www.diyitalia.eu/forum/images/smilies/Trilly-18-39.gif))
Many Thanks Steve
