They look OK.
I notice you countersunk the outer edge so I am wondering why you brazed the inside rim.
From the outside only enough should run to give strength without going to the inside making cleaning up easier.
2 cents worth.

Silver solder on inside as the outside rim has a groove cut for the drive belt

It seems to have a strong willingness to lift water...and possibly not as much surge or more "even" water stream than the popular Empire unit. I believe it is the upper basin that helps even out "surge". Well done.

Well i think it might be a fail
 First run did not work as brass pulley has no grip,for spring belts .
Filled rim with lead then turned and knurled with a threading tap .
Still no work with spring belts .
But does work with a rubber band , second issue is it not happy running one way as it appears to grab .kind of works the other  way

I have been thinking ( usually not good )
I am thinking maybe brass on brass  with cold water is not good .
Maybe cast a piston . Just not sure from what . Printers lead type , or mazac , or babbit bearing metal .
Also maybe I am asking a lot from a small pulley

Hey Dennis, I was going to say, Jim's got a post in this section below yours about cutting a gear with a tap,
but it sounds like you tried that. Maybe you should just make the groove deeper with a round bottom and try
the tap thing just in the bottom. Look at a Jensen or Wilesco pulley.
Brass on brass I wouldn't think could cause a problem unless you're dealing with heat.
Heck you made it this far, you'll get it.

Mounted a David Auld engine unit on some wood and a meccano lay shaft
All running from my electric test boiler for ease of use

This is pump number 2  ( Nicks ) if he still wants it

That is great to see Dennis!!

Been wanting to ask about it, but knew they ended up being quite a headache for you, so I kept quiet. Definitely still want it  ;)
