Good video bro, thanks for posting, this is the 3rd video I've seen designing the same frame, but yours is really easy to understand while still keeping it short. 👍🏻

StreetFlow Skateboarding thanks for the info it cuz I saw your video and wanted to make my own rail so I did but I forgot about the side walls thats why I asked.
