Dennis, Your guy sounds better than the offer I got from Chesapeake Rigging. They wanted $800 to do the seals and said the cylinder may be worn and may cost even more money.
You remind me I need to place a sun shield on my ram seal also. I was thinking of using a hole saw to cut a wafer out of 3/8 PVC foamboard and slip that down onto the rod. A stainless fender washer might work better if you can get the hole close to the -10 rod diameter. Or a combination of the two. Third idea: sacrificial O-ring on the rod above the seal. > On June 27, 2018 at 3:57 PM "Dennis C. via CnC-List" <cnc-list@cnc-list.com> > wrote: > > First, thanks to the list for all the helpful advice, on and off list. > > OK, decision made.
