Pete..............You must have missed this so here it is again

Note...............this is where Pete's "selective memory loss" kicks in

I should maybe apologize for stirring the pot but I'm in between a rock and a hard place. Ken buying parts just to check them out and Pete being a real life (I hope) resource I can meet and I play boat with.

I could never be Homer but he is my idol

Ken,
There's no doubt in my mind why you were kicked out of that other site.

Todd,
No need to worry. Ken will turn it around and sell it to a customer for $600.

That may or may not be true Ken but at least you didn't fall for this one

I’m curious about the pump too but dropping $300 on it because I’m curious and want to play with it and drill it is hard for me to justify, even harder to justify to Mrs. Orlando76. Kinda like women, I see some models I’m curious about but the Mrs. really doesn’t want me buying them for $300 so I just look at my proven trusty pump under the doghouse and think how lucky I am to have a good model.

Haha, shamite.

Well it seems like there's more to this story.

I just happened to have one of these pumps show up at my house today so being curious about things like the painted bearing housing that must be cast iron, I put a magnet on it and it was mildly magnetic, but not nearly as much as cast iron

Then I drilled a little dimple into the housing and I must admit, them South Koreans use some super penetrating paint, it goes all the way through the metal.   

So I figure this is a bronze alloy that's slightly magnetic

The pump housing is non magnetic just like the Sherwood pump

Then I took it apart enough to see the difference in the cam and internals.

The Sherwood cam is separate and held in with that external screw that everybody uses to get their pump mounting figured out,

The DJ has the cam cast right in

The Sherwood uses an O ring on the pump housing and a paper gasket on the bearing housing end with the end plate sandwiched in between.

The DJ uses O rings on both housings and no paper gasket.

And if you think it's weird that the bronze alloy is magnetic, grab a magnet and put it on your rudder, strut, NiBrAl prop etc and see if they're slightly magnetic   

I'm sure we can all form our own conclusions about which pump we like better.

Cole,
A fax to McMaster? Are you still in their big yellow catalog?

Both castings are magnetic, so I guess they are both iron. . And I bought the magnets at HF instead of faxing in an order to McMaster-Carr.

The surface finish on the machined flats and threads looked like it was done out of a single piece of bronze/something soft so they had me fooled.

I can confirm that the Sherwood bearing side is cast. I was tearing down the old pump today to sandblast it and i forgot about the snap ring in between the seal and the bearings. I was trying to not destroy the seal in the hopes of reusing it. The hydraulic press reminded me that the snap ring was still there. Hope the DJ pump works out well because I no longer have a spare

Maybe since he has the pump now, Wisco could take a magnet and see if the pump body and the bearing housing are both non magnetic unlike the Sherwood that has a bronze body and cast iron bearing housing
