Title: Pericaud water lift pump,
Post by: Scorpion2nz on February 20, 2021, 02:13:52 am
Mutter mutter damn and blast
Silly suggestions from some one who,shall remain nameless.

There will 3 and only 3 66%. Brass ones made

Silver soldered together and when the other two are done there will be some hand filing
And cleaning up to do.

Cheers
Dennis

Great work so far Dennis, you're slave driving those elves again....be careful mate they'll get unionised :)

Looking forward to watching these come together.

Nice project, the Pericaud pump is a good looking accessory and building it out of brass should make it even better than the original.

Some more progress
3 spouts made ( no photo )
  Then highly accurate eyechrometer for 90 degree hole for the spout
Milled then some hand filing

[attachimg=1]

All 3 spouts silver soldered in place but forgot to photo
I will remedy this tomorrow night .
Now the clean up begins to make them presentable

Yes you would be right
Far superior and the DRO is a great addition.
Bigger and better it makes things a lot easier.

  Been doing some the bit I detest.
Finishing ..
I silver soldered because I want life time strength but the nature of silver soldered make excess removal  difficult.
Any way

Not sure if tonight's episode is model making or light engineering.
Time for the base
Small sheet is 6 mm plate brass
Large shet is 3mm plate brass.
Damned if I am going to hacksaw  them so out with 4 1/2 inch angle grinder

Some time later a lit of chicken scratch

Well i learn’t something tonight.
I am a idiot .
Why did i mark out 3 parts when I was going to be using the mill with DRO.
It occurred to me that i only need to mark 1 and when milling note points
Then just follow the points for others .

Anyway a start on bases

Keep the brass sheet handy Dennis, you'll need another base for the special model Pericaud pump.

I hadn't realised you were building them in a smaller scale and they look very nice at this size. 
Have you thought of adding an oil cup or oiling hole to the bearing?

Did you miss the clue in my first post “ 66% “ and the second photo in first post

Had no thought about an oiler yet

You certainly did have a full weekend. I had an uncle who was a dairy farmer, and he worked in the shop.
Cow's came first, the shop, come home to the cows everyday. 
Those pumps are looking sweet.
Title: Re: Pericaud water lift pump,
Post by: Nick on March 22, 2021, 10:12:37 am
I like traveling too much to keep your schedule!

There was an old dairy farmer near us that supposedly never slept in a bed. He would milk cows and take short naps sitting on his stool out in the barn.

 I think they have curved spokes  and then a water test

Post by: classixs on March 23, 2021, 05:22:57 am
Great progress there Dennis, well done!

...and yup, curved spokes  ;D

In hindsight you could have aimed for the square reservoir model to avoid that...but then the base/reservoir most likely would have been more troublesome?

(Attachment Link)

I think the squareish reservoir  would not be to much problem
I would start with round brass tube and a steel former then silver solder a base inside .

Back to the drawing board .
F&^%$* pulleys
Turn on lathe brass to size with recess.
Then on to mill with rotary table .

This might be tomorrow job

Title: Re: Pericaud water lift pump,
Post by: Scorpion2nz on March 27, 2021, 06:30:43 pm
Plan B


We have a central hub with 5 holes drilled.
A outer ring with 5 holes on a angle
And 5 rods bent by eyechromotor

[attachimg=1]

Insert rods through rim





[attachimg=2]

Silver solder then some trimming on lathe



[attachimg=3]

Are they perfect ? NO
Are they acceptable? Still thinking

Post by: Steam Technology on March 29, 2021, 04:04:47 pm
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.

Post by: Scorpion2nz on April 03, 2021, 10:24:24 pm
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

Post by: Scorpion2nz on April 04, 2021, 04:41:23 am
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
Dennis

Post by: Woe is me on April 04, 2021, 07:04:08 am
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.
