Can I suggest that you add a detachable post to the opposite side to the cutting tool. This will allow you to set the tool position precisely using a gage block or spacer of some kind. Also you can use it to determine what point on the cross slide is exactly right for the ball to be perfectly round. A simple depth stop for the cross slide will also make it easy to avoid cutting too deep and getting a non round ball. I hope that makes sense and is useful. I enjoyed your video. Well done!
that was beautiful. I operated a lathe in high school and made my measurement tools, all my cutting tools, and made an all metal small ball-peen hammer, but didn't have access or knowledge of this tool to make the rounded end of my hammer.
Bonjour Doktor Phinn, Voilà un travail magnifique, que j'admire sans réserve. De plus, vous donnez suffisamment d'informations pour que chacun puisse reproduire votre outil. UN GRAND MERCI ENTHOUSIASTE pour votre altruisme. D'autre part, merci pour cette musique classique qui confirme, s'il en était besoin, l'excellence de votre travail. Enfin, je vous souhaite, ainsi qu'à vos proches, une excellente année 2022, avec la satisfaction de vos projets, et une santé exempte de soucis.
Fascinating! I'm not a metal turner, but I'm a wood turner, I'm sure you won't mind a small negative comment, made with no disrespect. I was always taught, not to use a cloth when polishing, but to use paper towels, as they tear if caught in the chuck or the work, it's safer on the fingers!
I made a boring head adapter that mounts on the side of my cross slide and accepts a 3/4" shank boring head. The micrometer adjustment makes things pretty easy.
Looks like the measures app. I’ve used it for years to talk to engineers while on remote jobs. I’d draw the parts I wanted, edit the measurements in, email or text them back to the shop to have them make modified or new parts and gold or red streak them to me. Cool jig! 👍 And it’ll last plenty long enough lol.
He sido mecánico fresador...durante casi 50 años y tuve un taller propio 12 años...mi especialidad eran fabricar moldes para termoplásticos de inyección y soplado tales como teléfonos las cajas de plástico que contienen 24 botellines de cerveza o banastas de plástico para frutas o verduras en bronce al berilio . También fabrique las hormas de cintrado para sacar los parachoques del Renault 12 y moldes para botellas de leche o aceite ... Hice en grafito para erosionar la hembra del teléfono línea Teide un electrodo que era grafito puro ( buen conductor de electricidad )
Um meio mais simples seria usar uma serra copo na medida da esfera que se pretende fazer e adapta lá na furadera manual. O torno gira e a fresa também proporcionando a confecção de esferas perfeitas.
Now this would have been done in minutes in a CNC , but where's that fun of doing it with our own fixture ,Our own Tool Mechanism , our own Tools , Take flowers 😇🌸🌸🌸 it was a good technique
O companheiro, só um palpite. Troca o parafuso do centro de fenda por um allem, aí o negócio fica 100% profissional. Fenda para um forte aperto em serviço de torno fica com cara de amadorismo. Mas a ideia foi legal. Parabéns.
Hello new here, Doktor Phinn. We have seen a few radius and ball turn for the lathe builder heck even one for a milling machine a knee mill that one amazed us sense he the gentleman has no lathe. Your ball turn attachment looks really nice however we would like to see (for wear over time purposes) a bearing in the base for smoother flow of operation and as for mentioned wear factors to both the ball turning unit and your lathe cross slide. We see you know it will not last forever (your text) but we wish you would it is really neat to see and want it to be around for ever. Not criticizing, just our wish, a desire for the finely made unit, Thank you. Lance & Patrick.
For smaller diameters, it works fine. But I see your point. I will however try to avoid the use of bearings to keep it simple, affordable and easy to make. Thanks for the comment.
