Anyone using this to mount carbon fiber motor mounts? What is everyone using for the twin cf mounts in these cats?
Scotch Weld Black for Carbon?

That is interesting. I have been just using a good 24hr epoxy by System Three. On the current build I added cloth support on the corners of mounts but this is the first I have done this on. The others have held up fine with no broken mounts even after the flips at 70 or so MPH
This stuff should work fine. Except for the 20 minute work time. -
I have used JB on a few mounts on hydro's, an never had an issue...But It can be difficult to use sometimes...in the "Neat" department.YOUTUBE-HyProBuildv1

JB weld has worked very well for me in my CF mounts. Even on my SAW boats that have had numerous blow overs at 90. Scuff the CG good with some 120 grit and wipe clean with alcohol. For clean lines, throw down some masking tape before applying. Apply the JB and your mount, run your finger down the bead if necessary to make a nice fillet and then remove the masking tape. The JB will sag a bit but you will have a nice clean install.
But to tell you the truth, I've never seen any epoxy fail that wasn't attributed to lousey surface prep.Attached FilesMike Chirillo

I have been hearing of this "G/Flex" epoxy on a few build threads lately, it was on my list to research, not sure which version people are using but I'll take a look again.....http://www.westsystem.com/ss/g-flex-epoxyMy private off road rc track

I just mixed up some JB with a pinch of black mortar pigment, certainly made it black!
The pigment is plain old carbon, anybody think it will effect the epoxy?
I'll post back later to let you know if/ how it cured and if a can feel any difference in bond using the highly calibrated hand pull test!

I use 30min. Zpoxy mixed with ground CF for strength and to make it black. Tape the edge and you get a nice finished line when set. Or if you're using with regular Epoxy fiberglass mix it with milled fiberglass to make it white. DSC02678.jpgComment

Epoxy pigment works great with G/Flex. You substitute it by weight for the resin. For black I've found that just a VERY VERY small amount is all you need.
