• 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
  
  Cheers

• 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
