OK Got the 4460 epoxy on order now $116 a pint + shipping.
http://www.cotronics.com/vo/cotr/ea_ultratemp.htmAlso have some CF sock in 2 different sizes.
It will over lap in the middle of the rear cone.
Also some 1" tape with out tails to build up the stinger so the small sock will conform to it.
have some 3 to 1 heat shrink on the way also in the 3" size.
With the stinger build up this should gust shrink enough.
This is one pricy pipe to say the least.
This thing better Fing work...............................LOL

well here is the last piece to the puzzle.
Looks like it will take some time in the oven to set this stuff up good.
4hr at 250deg to cure.
1-2hr at 350deg post cure
Then a final 16hr at 450deg to get all you can out of it.

Can it partially cure at room temp at all?
I saw some machinable blue wax that melts at 240F.

Well the 4460 dose not set up at room temp needs 250deg to set up.
Wax test at 250deg it melted.
SO you can not use the 4460.
Will call tomorrow and see if the 4461 that sets up at room temp is gust a different hardener with the same resin to try and salvage a few $$.
So no need to ponder if the 4460 resin will work with a wax mold it will NOT>>>>>>>>>>>>>>>>

Well it dose not set up hard enough to melt the wax out and hold the shape.
So on to the next test.
Aluminum ceramic adhesive thinned down to a liquid.
http://www.cotronics.com/WEB SHEETS/989 resistor NP.pdfSo it will be a CF reinforced ceramic pipe.
Here goes nothing >>>>>>>>>>>>>>>>>>>>>>>>
I knew that purple dragon would catch up to me some day......................

Well the CF pipe did not work out as I planed .
The pipe is to big and to much transition for one CF tube to do it all.
So ordered some aluminum stock and will build it out of that.
Well that set me back a few $$ and lots of time waiting around.
Live and learn.
Will play with it later in life when I have more time.
Should have this pipe ready to go by and ready to test by the end of Oct.
