Look up robotunderground on eBay. You can find cheap parts from him often.

isnt it just magnet wire wrapper around an aluminum tube?

Yeah but it's very tightly wrapped and its all glued together lol you would need a machine to do it

where would one buy said machine or is it something that has to be built custom?

If you are very patient... Not worth the effort though. Some good softparts, motors and frames to be had on forums. My .02$ get something with a 3" coil since they're the easiest to find parts for, and get a GOOD motor from the start. Coil/cone/spiders/tinsels/glue will cost you 50$+ regardless of whether it's on a flea market motor, or something monstrous. I wouldn't even bother with a sub that isn't worth at least 200$ built up.

I have some odd ball cones/coils/spiders here I'd let go cheap (1 of stuff that I'd never find a pair for, etc.) Hit me up if you are in the market.

Not rocket science, but you will probably break a few before you get a good technique. Use CA glue ONLY and keep a gallon of acetone. You can recover a coil a lot of the time if you only have mechanical failure.

You coming to the Sanford show this weekend?

From what I'm told it's like a lathe.

I've talked to a guy who has wound his own. You need to use aluminum flashing (forget how thick? I can ask him if you are really serious) and wrap it around a tube the correct diameter. You do a few winds at a time, then CA glue... repeat as needed. Very tedius, and you are limited to round wire only. Considering say a big *** 8 layer coil will cost you 55$ or so, it'll take you more time/materials/effort than that's worth to try to DIY.

ill be working this weekend unfortunately your probly right i should just stick to putting prebuilt parts together if i build i honestly just wanted to do it for the learning experience.

There is plenty of experience to be had in building a sub, but winding your own coils, if anything, is a waste of time.

i can see that i just tore one apart and i already understand them a bit better.

even with a machine winding ur own coils is for the pro's in FL.

Hey, SPL, isnt there some math involved in that as well as far as inductance?

winding isnt something you want to attempt, unless you know what your doing, but you dont technically NEED a machine to do it, lol if you wanted to start practicing winding start with a stater or armature.

yes length and diameter,material set the inpedence.

there is different resins (glue) to hold the wire and the good coils have 500F resin on them vrs china with 350f or lower...

This is a topic of much interest to me... I get old blown subs all the time, would like to do more with them then leaving them laying around.
