Unfortunately I'm not able to secure a reliable source for the spur gears anymore -- without 'minimums' (at outragiouse prices). I don't have the resources to buy the low number of units I need. Sorry. Spur gears like what I had used for decades are no longer within reach. So, the gear reduction units I once produced are no longer available from me.

Kinda sucks when companies chase the long dollar and leave the little guys behind, but we always find a way and where least expected sometimes too.

Wow, 112 o-rings per pour. That's got to be tedious work prepping the rods.

About how far apart are the two o-rings for each seal? Also, do you just spray the rods and o-rings with mold release, or do you grease them too?

1/8" spacing between the O-rings. I only grease the mandrels before sliding the O-rings on. Yes!... tedious work, but rewarding. These pushrod seals have proven to be near bullet-proof; a major improvement over the single O-ring versions initially produced.

David, while at Subfest you looked at one of my SD's to figure out water intrusion and immediately mentioned they were single o-ring seals. What gave that away?

The color of the resin bodies. Periodically, every couple of years, I change the color of the resin so I get a rough 'machinery history' on our products. I can identify large lots by rough date of manufacture.

Want a few more 'improved' seals, Ken?

Sure, the stubborn Skipjack SD I'm going to spend lots of time one of these days before Cabin Fever trying to figure out where that tiny bit of water is coming in. That was the SD you looked at. Might as well replace them with known double seals before I start. Will shoot you my address? You've sent me so many things you should have it.
