I’ve had great success with this stuff. Been using it to make fiberglass enclosures. Havent skinned a deck with it but have skinned other things. Holds up well.
Also have this stuff on a table that sits outside year round (hot summers and very cold winters, rain shine and snow) and its yet to fade or crack or anything.
I’ve had this issue on 2 focbox can-ed together. What fixed it in my case was just going into the vesc tool, selecting the side that is running sensorless and selecting it to run sensored. Wrote settings and was good to go.
I’ve heard good things about Raka epoxies. Several different resin/hardener combos to choose from. 127 resin and 606 hardener should be a good combo with a working time of 25 minutes.
They also have a sample kit with 12 oz of epoxy and a few extras for $23. If you’re careful not to waste too much epoxy you should be able to do a board with that much.
Drill/cut/abrade a hole in the enclosure, insert male side (with prongs, not with holes) and epoxy it through the enclosure. Solder wires on the back of it to the ESC.
Alright, thank you. Seems a lot better price for both. Does it tell you how much to add? I know the West Systems has a measurement of how much to add with each coat
All the Raka epoxies are 2 parts resin to 1 part hardener, except the special 631 hardener, which is 5:1.
Measurements are by volume.
They sell dispensing pumps for ease of measurement if you’re interested.
I suggest getting a scale and measuring by weight.
It’s a real shame to do a bunch of work and have your resin not cure properly from bad mixing/mixing ratio.
The Raka epoxies are designed to be mixed by volume, not by weight. Sure, you can calculate based on specific gravity, but it won’t give you nice round numbers. It’s easier (and cheaper if you don’t already have a scale) to just get some dispensing pumps and go with e.g. two pumps of resin and one pump of hardener.
The resins have a s.g. of 1.12-1.14, and the hardeners have a s.g. of 0.96.
The weights are close enough that you could probably get away with a 2:1 mass ratio and still be within the margin for error, but I’m just going by what their website says.
Pretty much. It’s better to mix too much and have some left over than to run out halfway through a coat and have to mix up a fresh batch. I’d guess somewhere between 3 and 6 oz per coat depending on how thick and how absorbent the carbon is.
