Hi All, thanks for all the comments and  I have now attached the gear to the gate rim ..I had to use two pieces together to get the depth.. When I silver soldered them together I used a centre punch on the faces to create room for the solder to penetrate  fully .
it is larger than the prototype  as I do not haven gear cutting equipment ..so used what I could find ...it will all be hidden so no one will see it ??!  I will also have to use some JD Weld to fill some of the gaps .

It may not be exactly to scale but it looks really good and gets the point across! :) :ThumbsUp:

The gate is now prepared by milling the slots with a 5/16th slot mill and then sawn out and filed to rectangular shaped openings. The piecing saw is quite old and made in Germany  the different parts are stamped  '77' ? and these may be hand made and numbered to keep the parts together ??

Great looking work, Willy! That saw is certainly a fitting tool to do that kind of work with. I love that hand made wing nut!
Regards,
Ron

The turbine mounting plate is now chain drilled and filed to shape and fitted to the flume ring ...next job is the lower skirt and bottom bearing support . on the prototype the lower bearing was a big chunk of Lignum Vitae...as this was always immersed in water !!!

Great work!


And I will have my shop elves guarding my old Lignum Vitae deadeyes to make sure your elves don't try to carve them up for bearings!   :Lol:   


Don't think I have seen that wood in the shops, though ebony is close and available, bet you have some of that in your instrument wood stockpile...

Does the gear segment move the flume blades to open and close the openings, or is there another gate to shut off the flow? Very interesting machine!

Hi Chris, the outside flume blades are fixed and the gate is the part that is inbetween them and the rotating turbine blades . the gate is the part that has the 4 spokes and they only move the width of the slots .. So  4am and am off to bed !!!..more work tomorrow ..G-night....!!

The flumes have now been made and they now need to be soldered into the support plates,,,however holding them all in the correct alignment to slot the plates together will be quite fiddly..about like assembling watches and clocks  together ??!!! I may need a few people to help with this ....

Looks like a good time to put in some small brass screws to hold things for soldering, easy to file off flush.

Hi Chris , I managed to  get all the flumes in place eventually and bolted the two plates in place and soft soldered everything together.. so everything going to plan ... the next job is the bottom skirt and lower bearing.
