Sounds good though, real good!

Thanks Tim

Amazing Ray!!

Sometimes I surprise myself.

Yeah that sounds great! How long can it run with the Oh-no rings?

Thanks Robert
The viton o-rings last a long time as some of them are over 4 years old.

I think it sounds pretty good. Next step cooling system?

Yes water pump next Chris

Sounds great! Great video.

Thanks Jamie

Sounds great Ray. Did you anneal the brass before trying to bend? I always do, as it makes it so much easier.

Thank you Jeff
I don't think the pipes are made of brass but just coated with something to look like brass. Very cheep!

Soooo cool. Sound’s great!
Congrats on yet another successful build.

Thank you very much but I am not done yet so don't leave.

Thanks to all for the kind words.

Cutting out the water pump impeller.


With a shaft installed.


Thanks for looking

This is the water pump housing I machined from a block of aluminum.


I turned it over in the lathe and bored out the cavity for the impeller to fit in.
I don't know what I was thinking but I went too deep and cut the base right off the stem.
Tomorrow will be a better day I hope.

Thanks for looking

Ray, I appreciate your occasional blunder (very occasionally) as it reduces my complete feeling of inadiquacy when reviewing your work. I realize that you are such a nice person that you make the occasional error just so us mortals will not feel so bad.

 

[rdean]

Jeff, I have a different design in mind for the next one that should be easier to make. I am concerned that it may leak around the shaft seal but will give it a try anyway.

Boswell I make mistakes every day but I can usually work around them. Case in point is the gas tank. If you look closely you can see a red spot on one of the ends. That is where the epoxy didn't get spread evenly and the gas just ran out there. I was able to work some form a gasket into that hole with my finger and seal it up nicely.
Thanks
Ray

Start over on the water pump housing with a 2" X 2" block of aluminum.


I turned the end down to 1" diameter this time and shortened it up some.
I Drilled a 1/2" hole all the way through and then bored out for the bearing.


I flipped the part around and bored out for the impeller and the inside bearing.


Drilled for 4 mounting bolts, made and installed the outlet pipe, and gave it a little shine.


Also cut a land on the front just for looks.


Now before someone asks why are there are two holes on the side of the pump I will explain that the first hole was a practice hole and since it looked so good I thought I would just add another.
Actually the first hole was a mistake so I will put a brass plug in there to give the pump some more color.

Thanks for looking

Any seal to keep fluid out of the bearing?

 

[rdean]

Jeff I have never tried this before but since there won't be any pressure in the cooling system I thought I would give it a try and see just how good the sealed bearings really are sealed. I have my eye on a couple of oil seals that could be easily installed by moving the bearing back in the housing if need be.
Thanks for asking
