So I'm making a ROTF leader Megatron Custom, and doing some research, frenzy_rumble used a ball joint for the Murder Arm, and I was wondering what ball joint would be big enough.

F_R says he thinks something from beast wars, but can anyone shout out any ideas of what toy(s) I could use?

Thanks!

 

Lego Bionicle joints work well, the big ones are 10mm.

 

Yeah Bionicle is best for larger balljoints, I think the only thing I've seen that's larger is the ball joint on ROTF Leader Primes feet, but even then it has that weird socket and such.

 

I totally forget about Bionicles! I'll try that out; Thanks!

 

Pick up some Struxxs from TRU, Huge ball joints work great!

 

yeah, the bionicles are a good size, but make sure you buy a set w/ black.
The BW (i think) figure I used was some sort of crab with claws and rubber treads...

 

It was most likely Rampage, I also have a question, how would you attach a ball joint to something that's never had a ball joint before?

 

I already cut the arm in half, and I'll put the ball joint on one end and the socket on the other.

 

Thanks, I was think of trying it on an extra G1 tf I have

 

Check out Sorlac333's megatron, he used a ratchet joint from movie scorponok. Its probably the cleanest megatron arm mod I've seen.

I used a balljoint but will change it to the Scorponok joint when I get a chance.

Just checked Scorponok, the joint doesn't have a ratchet because there are some mechalive gears in there. That shouldn't make any difference though. The shaft its on also rotates so it has motion in all directions.

I used a balljoint for a Starscream hand mod, it was way too small so I glued 2 rubber O rings to the socket to tighten it up.

Hakka.
