Default Stinger 1 Air Assist Connection Question

Hi, I have a first generation Stinger 1 and think I am missing a coupling between the air assist and the router plate (see attached photo). Also, I am not sure the air assist cylinder is attached properly.
Thanks for any help on this.

Pat, this is what it should look like. The assist rod should screw directly into lower swivel piece with a locking nut. It looks like you have some extra hardware.

Did the rod shear off?

do you know if any modifications have been done on the machine - specifically in the z mechanism or router plate, etc.? like added z height or something similar?? history of the machine, like mods or accidents, would be good to know.

it does appear that the linkage from the cylinder end to the plate mount is missing. if that is all there is to it, i suspect that all you need is a coupling length that you need to achieve.

does the air assist cylinder look damaged or misaligned??

Default Stinger 1 Air Assist Question

Thanks everyone - the picture really helped.
I think what happened is that a nut connector was used to connect the rod out of the cylinder and a short piece (2” or so) of additional threaded rod. I believe the couple nut vibrated loose. The bolts were not sheared - just uncoupled.
I have since removed the coupling nut and extra length of screw rod. Now it looks exactly as in the posted picture.
I’m the original owner, but only recently noticed the link was open.
Thanks again to everyone for such a helpful and fast reply.
Pat

resetting the linkage is critical. the air cylinder will have more travel than the z axis does. if you disconnect the air hose to the cylinder, you should be able to pull the shaft out and determine its travel. just to make sure that the z axis travel is within the travel of the air assist cylinder. otherwise damage may result, or the z travel will be restricted by the air cylinder travel. they might align the travel limit at bottom or top, check in with CAMaster techs

glad you figured it out.
