    Building my own high quality seals...

    After reading the chapter in Bob's book and watching his video on building seals for the WTCs, is there a good source for the cup seals and oillite bearings? If you happen to have part numbers to share, that would be great too!
    Now if you'll excuse me, I'm going to go on an overnight drunk, and in 10 days I'm going to set out to find the shark that ate my friend and destroy it. Anyone who wants to tag along is more than welcome.

          I used to run the aquatics programs for one the Boston YMCAs when I was much younger. My boss could never remember names, so he called me "that fish-boy" for the first month I worked there.

              You can do all that, or keep it simple stupid.

              5 minute assembly, Rulon bearings, Pushrod can can angle off center.

              I NEVER have moisture in my boats.

              A simple 1/8" pushrod seal

              FWIW, yes you can put Oilite in the wet, but Rulon (Also McMaster Carr) are designed to BE in the wet. NEVER need re-oiling. More forgiving in angular and concentric misalignment over time. Berfect for shaft component not only for shaft alignment, but thrust bearings.

                  Suppliers and part numbers were posted to the video that I put on my channel talking about how to build the seals.

                    Next time I'll actually watch the video instead of letting it play in the background while I work...

                      After Dive Tribe, I finally got off my butt and ordered some U-cup seals (1/8" ID x 1/4" OD) — the same ones from Bob’s video. I had to place a minimum order of 88 pieces, so I’ll have plenty of extras if anyone’s interested. They should arrive in about a month.

                            Compression fitting is merely a holder.
                            Adding compression could deform the cup seal causing it to grip the shaft and destroy the delicate sealing lip.

                            Make it simple, make strong, make it work!

                              That's an 'X' section O-ring, not a cup seal. Rommel's above explanation is right on point.
