Danke sehr! Ja, das hat länger als einen Tag gedauert. Ich habe etwa Anfang November mit den Arbeiten begonnen, habe aber nur jeweils an den Wochenenden einige Stunden daran gearbeitet. Und das Filmen nimmt erstaunlich viel Zeit in Anspruch. Insbesondere die Einstellungen für die Innen-Senkungen waren sehr aufwändig. (Stativ irgendwie zwischen Fräse und Säge eingeklemmt, 200er Tele-Zoom mit Zwischenringen, Baustrahler mit Messuhr-Haltern montiert ...) Edit: ich habe mir soeben mal Deinen Kanal angesehen und gleich mal abonniert. Sieht sehr interessant aus.
Very nice video Harald! Maybe i should have borrowed you my 75mm Drillbit for these bores 😉 Overall a nice project, i hope you find time to upload a video for the finishing steps, i enjoyed that length of the video 😊 Greetings from bavaria, Chris
Yes a 75 mm bit would have sped up the process considerably. Currently I am waiting for a grinding wheel. I will certainly do a follow up video showing the balancing of the wheel and the first grinding attempts.
thanks for your suggestion - however, I am not sure, if I understand you correctly. I am aware that turning an outer and inner cone with identical compound slide setting leads to matching cones -at least as long as the headstock is aligned correctly and the tool is on center height. In my case I did not machine the cone of the spindle nose. It was given by the manufacturer of the spindle. Thus I had to sweep it with the indicator to set up the compound slide. I turned the OD of the initial "reference cone" with this setting and used this cone to check for the correct cone angle using the inner cone of the flange. (Which came with the spindle and matches the spindle nose.) The ID of the pulley was turned with the same compound slide angle - as you suggest. Edit: sorry - I got your point: you are referring to the 1° double cone of the pulley crown. Yes, you are right, that would have been possible. Thanks.
Great video thanks for uploading. New to your channel and will be coming back for more if they are all like this. After all that cast iron I bet your handkerchief looked a tad black.
Thank you very much for your kind comment. I am glad that you enjoyed the video. Most probably I will do a few small videos with "tips and tricks" and a follow up to this one showing the spindle in action in the near future. It will take a while until I will be able to publish an other "full" video. (I wonder how other machinists manage to publish a weekly video.) With regards to the black handkerchief: yes, indeed, you are spot on. Machining cast iron is a messy business but it machines really nicely.

Lovely work Harald. I do like these old German T+C grinders with the really long work tables.

Thanks very much! All the best also to you!
Kudos for your patience opening those bores! Happy new year!
Excellente Arbeit. Da war das ganze Programm fällig. Hat wohl länger als 1 Tag gedauert...😳👍👀

great work next time use a boringbar for the seccond cone takes just one crosslide adjustment and both the same (pouli)
