Started off by Polarizing this old '70s fiberglass deck I've had since I was a kid ('90s garage sale find). The back truck was always broken so could never skate it (brand is "Pro-Class"). Followed all the info here in this thread and dug around the Blender insta page and the hashtags for confirmation and tips. The fiberglass deck is super flexy and fun. It's got some wood inside but fiberglass all around.
- Sure Grip Century extended 4.5" axles (with 4 - 6 speed rings on the insides of the wheels to give clearance)
- Yellow PowerDyne Hop Up Bushings and Bones Mediums on the bottom
- Bones Super 6 bearings
- Modus axle nuts with the plastic grip - cause with all the speed rings they may still stick out a hair
- Powell Peralta Skate Aid 78a 59mm wheels -- these things grip like crazy. you can take turns going insanely fast, and if you've got your weight right and heavy on the back, you'll pull it off with no powerslides. It's unreal. Ebay had them.
I had to re-drill holes because the Sure Grips were juuust slightly smaller than what was on here. Decided to move the trucks back about 3/4" because there was too much tail happening. Wheelbase ended up being 16 5/8" from axle to axle centers.
If you're looking to bolt the trucks in to the deck check your hardware store. I used #8-32 x 3/4 inch machine screws, some round and some flat head, with #8-32 machine screw hex nuts (they seem about 6mm thick). It's a tight fit, you'll need to hold the nut in place flat against the base of the truck, THEN screw the bolt in through it while you forcefully hold it in place. It will not slide down on to a bolt that you've stuck all the way through like on a skateboard. If you can, drill your hole angle slightly away from the truck towards the board's edge. This made it way easier for me.
And if your trucks and kingpin don't come with a bottom nut I used the 10-1.25 Hex nut/Jam Nuts from my hardware store.
I really wouldn't recommend buying anything from Skates.com or Rollerskates.com (same place). Seems like it's turned in to a scam this year, apparently the SF shopfront shut down a while back. I know it's the top search on google, and you can find a lot of this stuff in one place there, but a lot of people have ordered and paid and never received anything. Some people (myself included) had mysterious charges months later. Check twitter or google reviews. If it works for some people that's great, but I wouldn't risk it ever again. Their phone number goes to a full machine and they don't reply to emails. I tried throughout March and April. Sketchy
I used sk8ratz.com and backalleyskates.com for my top half Trucks (our hangars) and bottom half Hangars (our baseplates), Kingpins and bushings. Email them if you don't see what you're looking for, they can get stuff in. That's how I found the Sure Grip Extended Axles.
Will post my homemade one next
