Here's a list of the stuff you'd need to make your own:
**Supplies**
- Vintage water ski
>If you're going to sand and paint it, one that has some dings or imperfections in the paint will be fine, usually those will have a lower price (or will be easier to get for a lower price).
-Double King-pin trucks, I used 10" Gullwing Sidewinder II's found on Amazon for $70-$100.
>100% worth it, they're awesome trucks for a super long longboard like this. Single king-pin trucks won't get the same turning radius as doublers, unless they're really close together, and then it just looks odd.
-Mounting hardware, I used Fireball 1.5" flat-top hex screws. ~$10
>1.25" also works. Make sure to measure yours first to make sure.
-Bearings, I used Bones Redz. ~$20
>Longboard, skateboard, roller skate, rollerblade, and scooter bearings are usually universal. Same goes for the wheels.
-Wheels are 76mm cruiser wheels, I might get bigger ones though. ~$25
-I used a couple of rubber riser pads to reduce jolts that might mess with the electronics, they're about $6.
-Grip tape. Try to do a pattern, solid grip tape on this doesn't look right, and the wood underneath is pretty.
-For painting, I used Rustoleum protective spray enamel, blue, light blue, white, and for a final protectove coat, clear. I did 1 coat of the colors, then for protection, 3 coats of clear on the top, and 7 on the bottom. I used blue painters tape to do the stripes.
-RGB Lighting is the same as the ones you can put on your walls in your bedroom, they're about $30
-Battery box holds 8 AA batteries, here's the link because it was a pain to find.
**Tools**
-A drill, or a drill press. Drill press makes it a lot easier to get the holes straight down. May want to have someone help you with this, it can be tricky to balance the board on the drilling platform.
-I kinda just eyeballed the bit sizes, you just need two. One for the screw holes and one for countersinking them if you use flatheads.
-razorblades for the tape, cut it from the back, as it'll destroy your razors if you cut from the sandpaper side. It still ruins them, just not as fast, so buy a bunch of blades.
A random orbital sander paired with a shopvac or a dust collector makes sanding extremely easy. If you don't have one, this will be the longest step. You don't need the dust collector though, and make sure to wear a dust mask, with or without the vacuum.
-Soldering iron for the electronics, hacksaw for cutting a slit in the battery box for wire management, and if you have access to one, a 3D Printer. The files can be found on Tinkercad, just go there and search "RGB longboard"
That's about it.
This build took me about a week, working on it here and there, don't rush it.
