Here is the video of the same part made from some scrap piece of bronze. I guess it didn't last long because I'm already making a new one. • Spherical Seat | It di...
Quite a job! Reminded me that I used to grind telescope mirrors to spherical or parabolic curvature. Thanks for letting us watch. Enjoy your weekend, Chris. 😊
manual lathes use a "ball turning" to cut smaller to medium concave radius. Somewhat larger radius spherical seats can be machined on manual lathe by inserting a rigid "pump rod", of radial length, between tailstock and tool post. pump rod usually had small spherical tips, similar to an engine's valve lifter pushrods. The carriage is free to follow the arc of the pump rod, along the Z axis, as the tool feeds along the X axis. Some manual lathes also used flat metal tracer patterns mounted on the ways, with a follower on the carriage (or cross slide, depending on shape to be traced)
Chris, with all due respect the next time turning brass I suggest you should try uncoated inserts, Ceratizit or Iscar would be the best. Increase tool life and better surface finish. Kind regards from Comombia!.

Beautiful job mate
Did the customer supply the material for the original part? I hate it when the customer insists on supplying parts/materials.
They sure did
Nice job 👍 fun to turn, but not so fun to clean after that 😬 and i always feel that it is al over my skin with brass or bronze😆
Отличная обработка, я сегодня точил похожую деталь.
I wonder how this could be made WITHOUT CNC?! Easy enough with it.
Cutting spherical profiles is easy without CNC
@@canonicaltom Thank you for that uninformative assertion
@@paulwomack5866 Use a radius bar.

Let's make some chips!
Nice and easy
Where is your shop?
beryllium copper?
do you create these drawings on a drafting table?
nope, they are supplied
Привет Крис! Vc?
I hope you charged him twice for the unnecessary added work
I remember that, how much time and effort would the customer have saved if they'd just done it right the first time? 😅
I know, right. 14 minutes vs. 2 minutes. 😅😉
@@ChrisMaji can cut it down to 1 and a half if you want 🤣
Came out well mate 👌 thanks for sharing 👍

Spherical lap?
🤩🤩🤩👌👌👌
