It really depends on the weight (thickness) of the fiberglass youâre using. For an enclosure with no mechanical/structural loads on it other than its own mass, Iâd say 1/16" (~1.5mm) should be more than sufficient. Youâll have to figure out how many layers of fiberglass are needed to make up that thickness though.
Polyester resin can be used with vacuum impregnation, but itâs not ideal for several reasons: Itâs really, really smelly and attacks many materials, such as rubber gloves. Itâs also hard to mix perfectly because the ratio of resin to hardener is so high (drops of hardener to ounces of resin), itâs setup and curing time is very dependent on the temperature and the amount of hardener you used, and it is pretty viscous which makes vacuum impregnation even more problematic.
Having gone through this whole process myself, my recommendation is that you save yourself a lot of hassle and just buy some good low-viscosity epoxy resin online.
Ok, Iâll take that into consideration. Havenât looked into it that much but I might run into problems having the resin shipped to Iceland. I already have polyester resin so I might do some tests with it make a small scale prototype.
If you go forward with polyester, Iâd recommend working somewhere cool or cold during the initial steps to make sure you get done with your layup before the resin starts to kick off, and also donât try to do vacuum infusion - Do a wet layup and then vacuum bag, because the resin is too thick to flow for infusion. Once youâve got everything wet out and bagged, you can warm things up to speed up the hardening.
Be aware that the volume of mixed resin has a great effect on pot life - a small scale batch will cure much slower than a large one. My last attempt at fiberglass with polyester was a partial failure because I mixed one big batch and it started to set up before I was ready.
What else do you want us to say to an absurd question like that? Itâs a lawnmower. This is an electric skateboard forum. It has literally no utility or relevance. Itâs like me asking âHey guys, I have a bag of rocks. What can I do with it?â
Depends if your board has been weatherproofed or not. Stainless steel or ceramic ball bearings, conformal coating on all electronics and on motor internals, etc.
Anyone know any battery builders in Canada? Or willing to ship at an affordable rate? Iâm in Toronto and looking to build a 10s6p using 30T cells, stacked config.
I live spitting distance from the ocean and I have done none of those things on any of my builds. As long as you donât chuck it in the sea you should be fine.
IIRC itâs 150K+ on Vedderâs 6.x hardware, dunno what the actual hard limit is. Iâm sure it depends somewhat on the exact physical board layout so the flipsky might be different than the reference version.
Thatâll protect you from most things except a direct screen-down on asphalt or concrete. If you want more durability Iâd suggest getting an action camera - A GoPro session or a chinese gopro knockoff. Cheaper than a phone and much much more durable.
And you can put it on a helmet or chest rig or etc - The possibilities are endless and you donât need a hand free.
