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. 😊

Figure-8 motion, and three side-steps every 5 strokes or so, as I recall.

Came out well mate 👌 thanks for sharing 👍

Отличная обработка, я сегодня точил похожую деталь.

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

I remember that, how much time and effort would the customer have saved if they'd just done it right the first time? 😅

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😆

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!.

0:17 - Upper dim: Looks like time for a new drawing Rev. Ditto - One of our products has the same sort of geometry, but we do not spec a dim such as the 14.8" D, as it is nearly impossible to confirm. If our C/L, (correct) thickness and R dims are good, that simply becomes an irrelevant "Reference D". 1:10 - 'Nother "ain't gonna chatter on me" cutter choices.

Nice and easy

👍👍👍

I wonder how this could be made WITHOUT CNC?! Easy enough with it.

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)

do you create these drawings on a drafting table?

Let's make some chips!

beryllium copper?

Spherical lap?

I hope you charged him twice for the unnecessary added work
