Hello to all the inhabitants of our sites, the weather doesn’t allow me to do it now, so I want to get good advice from young masters in advance, maybe there are some aspects or nuances that need to be observed in creating a wood lathe, I want to create it correctly from the technical side, and take care of the appearance of the machine. I am also attaching a video, you can respond there too
[media = // www.youtube.com/watch?v=TDNUNt9Bkbw]
To a greater extent, I wanted to hear advice regarding the front headstock, the rear and the bed itself, and of the engine attachment to it. Cooling, for example, I have already decided and added a cooler for this.And what about the front headstock, I also tried to solve this issue, but with centering, not everything is so smooth, since there are two, not three, bolts. Who has any suggestions about this, some photos are in the video, I also advise you to look. I will be glad to your advice and various tips.

In ancient times, they came up with a simple scheme for securing a workpiece in a lathe. The main centering support is the spike-type cones (hence the word "bearing") from both ends of the workpiece. The rotation of the workpiece was transmitted using a belt or cord thrown over the workpiece. Another option - one stud was inserted in the center of the axis of the drive motor, a spoke was attached to the workpiece, movement from the engine was transmitted by another L-shaped spoke fixed to the axis of the motor. I hope I clearly wrote.

Well, I had in mind that if so, then they must be sharpened very sharply at a very small angle. To deeply eat. And all the same, it may not be possible to clamp if, say, a knot gets into the workpiece. Well, alignment, at least approximate, is needed of course.
.. And with "my" design, the blank with a cut is clamped to the end with an end face in the coupling. At the same time, the stubborn teeth do not allow her to jump sideways along the cut.

Thanks for the advice, in principle, yes, I saw such a principle on a lathe at school, I’ll try to repeat something like that.

And with this design, even if you sharpen all the teeth well, when you clamp the workpiece, one will rest against a harder area and will warp the workpiece sideways.

The first mistake of such a comb is that there is no center. The second, to arrange the teeth around the circumference so often will lead, at the slightest load, to a “breakdown”.

"Muse" she does not go to every fall. And does it even go ...
 
Among poets and other prose writers, she usually flies, not walks! ))))) And with us, masters, she, as a rule, is also home-made, so it can be either skilaryas, and on wheels, and even on tracks ....))))
... But, in terms of "walks" ..... Well ... Unless, try to collect the walking muse on arduino ....: smiley:

And what prevents you from adding a third? Drill, thread and that's it.

Although, in general, in my opinion, I would not do such a design of the headstock. I would make a flat “fork” with three teeth - then you just do a diametrical cut in the workpiece and the “fork” enters into it and then bites your teeth into the wood. It’s more reliable - it has a stop area with a torque much higher. It is not difficult to make it - if you wouldn’t cut this part, but just make a diametrical cut in it, then you could then put in it a flat trident tooth fork made of steel, say 3mm, and grab it with welding.

And with this design, even if you sharpen all the teeth well, when you clamp the workpiece, one will rest against a harder area and will warp the workpiece sideways.

Well, something like that, only symmetrically and not crookedly :))))

Smiled ... from the "Young Masters" who do not know the basics of sopromat
Here I look that it is necessary to take (exams) to the University (architectural and art)
1. Figure sculpture
1.2. Still life drawing of geometric bodies (spelling from their dumb site)
2. Architectural composition
3. Russian language
4. Social studies.
