here is some of the best shit i have found
check out this instagram, they always post good shit
@skatediy
the best shit to use i have found after working on our DIY is the following
when you are doing the final layer and your ready then add in portland mix cement to the concrete mix. i dont really use a set amount just enough to thicken up the conrete and give it the smooth layer you want
when you are working with cement it need something to hold it together. i use chicken wire because its cheap. you can use fencing, wire, rebar is what your suppost to use but if you cant cut it then your fucked. if you dont use something like this then your shit is going to fall apart and break over time.
its best to have your tranny cut out of plywood to use at a template and help you get the perfect shape
a few things you will need to get the job done
wheel barrow
shovel
LOTS of water (you should have a water supply near by or else you are going to have a shitty time mixing the cement)
finishing trowel
wire/rebar
something to cut your wire
lots of homies to help
pretty much you can do whatever you want and working with quikcrete is pretty easy. the more you do it the better you will get at it. a few links below for better how tos and shit. for sure check out that instagram though.

cement is cheap like 5 bucks a bag. to build the quarter at our DIY i think it was less than 100 bucks. there are pictures of it on my instagram @joshyoungmi
