I have a question about a screen door closer. Actually I'm looking to build some pneumatic props as outlined by Steve Hickman at Terror Syndicate. The majority of his home made prop designs call for storm door closers. I'm not sure if I'm going to go the route he details or just buy the air cylinders.
The question I have is what is the standard stroke of a storm door closer? And is there a particular bore size I should be look for if I decide to buy the air cylinders as opposed to modifying storm door closers? Thanks.
