how would i make some bc platforms?
It really depends on what materials and tools you have to work with.
I think that Evan Byrne had some plans on here somewhere for ones made out of square tubing.
have any idea what i can search to find it?
I just did a search for BC plate and found these for you. not the threads I was looking for but they should help you get the idea.
evans design looks really strong just needs to be a bit wider looks a little skinny. Ill give that design a try once my Nieghbour comes back from cuba (hes like pro at welding)
i made some like evans that worked really well. he also made some things out of angle iron that bolted on to catch his feet for jumping. he was going to make one with a brake before he dislocated his shoulder but idk how that turned out.
