Hi Ernie,
I have the same shear that you adapted to pneumatic operation and I'd like to do the same to mine.

Do you have templates of the brackets that you fabricated and would you share them with me (yours looks awesome... no point me reinventing the wheel!)
What are the specs for the components and where can they be had?
I'd be grateful for any tips you could pass on, too.
Thanks.
Michael
