RE: Tympani IVA

Hi Satie,
In '95 Magnepan refurbished my T-1D's & it was amazingly inexpensive. I would much rather do it that way again, but frt nowadays ruins the repair deal & they don't make 'em anymore.
I almost feel like getting a patent since I couldn't find any info anywhere at all.
Magnepan's video shows a square machine pressing up from underneath so I thought they must know what they're doing.
Being a BSME major/EE minor, I know there is almost always a cheaper, EZ'r & better way 2 do things.
I thought & I thought & I did & I did & each time I felt finished, damn another even EZ'r idea/method came 2 mind.
1st I used Mags way but w/o having that massive machine or the room, I used upside down w/weights. It worked so-so but was never quite taunt enough.
2nd I made a picture frame & laid it ontop of my 1st way. Then I stretched the picture frame on another fixture & Viola!!!
This made me think of when I do plaster work: U can almost never sweep it perfectly in one step. It almost always comes out better doing 2 steps & w/o the sanding YUKKK. Well I thought I was finished & AGAIN, damn I figured an even EZ'r, quicker & a (ONE STEP PROCESS).
Think of a round swimming pool cover, a rectanguler trampoline & a bedspread.
One person can slowly go around & around & get it tight cause it's a circle w/totally even tension, but a rectangular trampoline usually requires 2 people cause tension's not as even.
3rd, 4th or maybe 8th time, think of blowing up a balloon: it expands evenly from a beginning point or edge.
U have 2 pull 3 sides away from the initial fixed side.
I seen somebody on the web looking frustrated as they were looking down at the mylar laying on a table. LITEBULB: bedspread method.
My EZ method requires only ONE 3/4in thick, 6ft x 20in sheet of plywood & no weights at all.
Glue & clamping has been conquered.
This should be enuff 2 get U going w/o all the waste of time I & many others R still going thru.
I can give U the finally EZ details if U can get me info on WHERE I can get voice coil wire &/or the newer aluminum ribbon tape.
I C alum tape in the local stores but I need 2 know which one works correctly & w/time!!
Thanks,
Steve
