I have a 21t digger lined up just waiting for the owner to finish his current job. Machine is plumbed for a breaker so I'm looking at building a thumb for it. While I'm awaiting I'm starting to look for a second hand cylinder. I have a couple of old ones off of a 70hp tractor f.e.l but have a feeling they are in the small side. Does anyone know what would be a good size cylinder for a thumb for this machine, it has a standard stick?
Cheers
