I always wondered how often you got to sharpen your tip on that lathe

@@robbykwizz555 what do you mean with tip? The Carbide inserts?

I'll try to translate .... Everything is fine, but welding the handle is like a fly in the ointment in a barrel of honey. By simple welding, I ruined everything.

you chose a great line of job. i’m sure you’ll also become one of impressive machinist.

Thank you, yes i know the welding is bad but it its working very fine

How long did it really take you to turn round into square? Could have saved time and wear and tear, on your machine and inserts. .03 is a small cut, it must have taken you a day and a half to make a round blank square. Feeds and speeds, also material selection save time and money. I know this is a shop project, it just seems to me to be alot of wasted time. Time is money atleast in the 🇺🇲!

There is no way this project was made in a day (unless your talking 24 hours). And I would bet it was closer to 40. It's crazy to think someone with baby cuts could make this in a day. It is a great part high quality. But to think this was made in a day is ridiculous. Mabe if he started with the right material to begin with. I'm not knocking the part, I'm just not satisfied with the process.

@@albertpierce6263 i can't exactly tell how long it took but this was the only option for me at that time, because i dont have the Equipment to cut that efficiently. By the way who told you that it was made in one day lol, it took me weekends after weekends since i have a day time job

You need to look at your tool cutting height. Those blue 60 degree cutters are not on the same plane. You seem to be high on tool location. It's always better to be slightly lower than above center. Also invest in a good drill sharpener, or atleast a machinist drill guage.

если он на таком выносе вал точит с писком остальное уже понятно..........

@@user-fh2iy9ug9p резьба это отдельная тема у всего видео. Эт капец

Заводская резцедержка (с термичкой,шлифовкой,годовой гарантией) стоит чуть дороже 100 американских рублей. Думается сам по себе процесс,как таковой,стоит во главе угла. Или человеку делать нечего.

Вопрос токарям:для чего или почему шляпки болтов на резцедержателе квадратные?

@@user-ow6eu1dj1v Чтобы неповадно было их где-то использовать:)

Look up vids of making cubes on a lathe. Nothing is impossible on a lathe.

The lathe is such a universal tool, its just an amazing invention. But yeah i admit, most of the time i have to ask myself "how can i do it using only a lathe? " haha

I know ahha

He's a machinist not a welder😆👍

Ủa thợ máy là không biết hàng hả bạn

If my welding was not good and with his skllls I would’ve drilled and tapped that piece for the handle. Would’ve looked better.

@@khangtrankhangtran9430 thợ máy nào cũng phải biết hàn,nhưng hàn tốt hay k là 1 chuyện

Thank you, yeah it was difficuilt without a mill but not Impossible 😏

Would have been sensible to use a saw (if available) to get most of the waste off, before making the stock accurately square in the lathe. Getting that amount of waste off using a lathe, in an interrupted cut, is not a nice operation.

Thank you for the comment. Yes i know how horrible the welding was😂 but i have to learn alot

e o parquímetro sendo usado para riscar

Thank you 😁

Oorale.. suena interesante amigo ,🔩

🤣 well i was scared too at the beginning

😁 this is very nice to hear, thanks 👍🏼

Well alright, cool!

No problem and thank you

Thank you

Thank you for the advice. Right now im feeding only manually so its hard for me to get the right speeds and feeds but most of the time it does the job

@@yak-machining it's not your fault. See while facing, the outer regions have a great finish, but as you move deep into the circle, the finish gradually starts deteriorating. That is a tell tale sign of work not spinning fast enough. As tool moves inward, the rpms remain same but the linear (tangential) velocity with respect to cutting point decreases. (V=r x theta) Sorry I'm an engineer 😅😋

Thanks for the advice, sadly i don't have the equipment for brazing and at that time my old lathe (from late 1800s ) couldn't do threading. However i got a newer lathe (from 1919 lol ) and i have to restore it so i can thread

Repeatability on tool clamping? The tool should rest firmly against the inner vertical edge of the tool post (otherwise you increase the risk of chattering or the tool shifting), the slight angle on the bolts help pressing the tool against it. The bolts alone shouldn't be the only thing supporting the tool I was thinking to myself when he made the threads "hmmm. those threads aren't exactly straight", but then thought that it actually serves a purpose.

@@HepauDK Having the tool rest against the vertical edge is handy because the tool is aligned, as for clamping by definition vertical bolts do not exert any force in the horizontal direction. Also I don't think it is necessary as the main cutting force is pointed in the downwards direction. If a true two-surface clamping was desired then I guess the bolts should be at 45 degrees which is difficult because there is little room, only set screws would fit, and also there would need to be a 45 degree flat surface on the tool. One of the problems I see with the design here is that the bottom surface is very thin. On my current 4-way post this is 15 mm and even this I consider not much, in fact the block is warped from the clamping force. Unfortunately the dimension cannot be increased because there is simply no room. The only way would be to lose the compound slide as some do but I can't do without it. I will first re-machine the block and finish the bottom surface with clamping bolts tightened with 'dummy tools' so it is corrected for distortion. Lastly, I see many 4-way posts which fit on an accurate cylinder as well as the bottom interface. These two can never be combined (the cylinder will never be perfectly perpendicular) so it is better to have the post spin on a cylinder of very small height (only a few mm's) so that clamping force will always join the bottom surface solidly. Hope this makes sense.

Thank you

I just really don't see the need to weld the lever handle as it's already threaded in.

😂 yes i know but im not motivated enough to correct that right now, maybe someday

@@geoffdl03 no it wasnt threaded in, no thread was involved at all, only the thread for the center bolt but the handle was loose, so i had to weld it

@@yak-machining I am not a machinist, but in both cases where you used welding, I can see easy solutions without welding and a lot better looking result. Just threads, to special made washers, special made screw and some Loctite. Or instead of the screw, a little welding, but it will be in a position that doesn't matter how ugly it is, it will be very easy to correct in no time, so the welding will no longer be possible to be seeing.

Thank you very much

Согласен, портит все изделие

Thank you

@@yak-machining broo you halp me

Thanks mate, i wished i could threaded it but it was very difficuilt to thread the big nut without a milling mashine or proper clamping setup

@@yak-machining I just noticed your profile picture; it's awesome bro!

Thank you but I sold everything I own and basically gave up this hobby. Maybe in some years or not

@@yak-machining thats the last answer i was expecting. Sounds like you had troubles. I hope one day youll be back cuz you are a pro

@@Vigopl thanks, yeah it cost me so much money that even my family had to intervene 😂
