[Extended version] Bowl turning without electricity: on the pole lathe - Jero & Pirmin Lehr
Ғылым және технология
In this video, Pirmin Lehr shows how the bowls from "woodculture_handcarved" are made, in fact, two from a single blank. We use only traditional hand tools: a side axe, a compass,turning hook tools (here only with a straight shaft) and our self-built foot-powered pole lathe, much like it has been used since the Middle Ages.
This is the first German video here on KZread about pole lathe bowl turning.

This video is an extended version which shows the manufacturing process not fully, but mainly in real time. All in all, making the two bowls took us ca. 2 hours, of which 1 1/4 hours were needed for turning. You can find a short version here:

CONTENT:
To begin, a piece from a fresh birch log is split in half and cut to length on both sides with a one-man crosscut saw. The wood around the pith of the log is removed, as it is prone to cracking, and the top is hewn flat with a single-beveled axe so that the outline of the bowl can be circled. The same axe is now used to hew the blank into a roughly hemispherical shape, first hewing away the corners from below, then working out the outline.
A "mandrel" with iron spikes is now hammered into the axed blank, around which the cord (hemp cord) of the pole lathe is then wrapped, which is connected at the top with a rubber cord (traditionally a long wooden pole), and at the bottom with the treadle. After mounting in the lathe, the turning of the outside can begin. We use well-sharpened hook tools with which to cut on the downstroke.
During the roughing-out the blank is turned round until all axe marks have disappeared, further shaping and turning of the surface follows with a thinly ground, freshly sharpened hook, with low advancement.
The bowl is then unmounted, turned over, remounted, and the rim turned off and chamfered. This is followed by turning out a channel about an inch wide, primarily with a right-ground hook ("tip down"), with which the core is undercut further and further. The wall thickness is checked by feel and with the aid of a caliper.
Finally, the bowl is polished with shavings, unmounted and separated from the core by splitting it off with a bent gouge, so that a smaller bowl can now be made.
To do this, it is axed off at the bottom, centered, turned on the outside and hollowed out on the inside, just like the larger bowl, but only a thin core is left standing, which is then broken off. (While turning, you can see a leather strap here, which is more durable than the hemp cord). Again, the centers are cleaned by carving, outside with the gouge, inside with a large hook knife ("twca cam").
Finally, you'll see the carving of the maker's mark of "woodculture_handcarved", a simplified tree of life with a K for "Kultur" attached (German for "culture").
The two bowls are now allowed to dry for about 2 weeks and will later be oiled with organic linseed oil.

Beautiful workmanship. Proof that you don't need electricity to turn out useful things.
I am in awe. True artist and craftsman.
This is a great video - it's nice to see someone using a similar process. There were a few points that I will introduce in my work.

Thank you! We’re happy that our video is helpful for other pole lathe bowl turners. We‘ve changed a lot of details since we made this video, we hope to release some new content soon, but it‘s quite time-consuming as you may know.
The next time I see someone say 100% handcrafted, this had best be what they mean. Lol. Beautiful work, thank you for the content!
Very! nice,.... Thanks for sharing.... Never turned more than one out of a log. Going to try that!
Great video thank you for sharing look forward in seeing more turning

Nice sharp tools!! I can hear it!
Maybe I should learn to do woodworking this way. I'm both too poor for large power tools and need exercise, so this appears to serve both rather well hahaha. Edit: I also love the wooden work shoes!
Good
nice video dear

Thank you (although they aren't self made). Making wooden shoes on our own with traditional hand tools is a very interesting, but extremely demanding and time-consuming project for the far future.

Why the lathe was in the beginning of the video powered by rope and in the end by leather belt ?
@holzkultur_handgeschnitzt

Thank you for your comment. We started using leather belt during the time the video was made because it is more durable and easier to maintain than the hemp cord we used before. The turning of the smaller bowl was recorded a day later in the workshop where we used the 2 cm wide leather belt, which only runs cleanly if you use a sway bar at the treadle. For the main part of the video, we set up the lathe in front of a better background outside the workshop, and to avoid having to set up the sway bar, we did without the leather belt. In the meantime, we have a only 1 cm wide, thicker belt that also works without the sway bar and so far serves very well. Traditionally, bowl turners mainly used leather straps, rarely hemp rope.
It looked like bungee cord for the spring effect…is that what it was, instead of a spring pole?

In this case yes, but on medieval markets we use a traditional spring pole, as you can see on some photos on our instagram account woodculture_handcarved
Lovely! My friend has a treadle lathe but nothing like those hook tools. I’ve not seen pictures of English Bodgers (chair leg makers) using them either. Do you know if they’re a mainland Europe thing or a bowl making thing? Perhaps I’ve just missed them…

Hook tools are used for bowlturning and end grain turning (cups etc.) They are not used for spindle turning like chair legs. It is possible (e.g. for turning the outside of cups, especially those with a handle) but for normal spindle turning not usual. Their advantage is the long handle, cutting edge position and ability to cut without moving your position a lot. Hook tools were used in all parts of Europe as well as in Asia. They are very old tools, maybe older than turning gouges and chisels. They can be used on pole lathe, treadle lathe or even modern electric lathes. Most modern turners use them only to reach spots they can't reach with the gouge.

@@Mulletmanalive Normally treadle lathe means a lathe with a pedal, flywheel and drivebelt. It has continuous rotation (not reciprocating like the pole lathe). You don't need to wrap a cord around the workpiece. It became common in the 19th century and is much more complicated than a pole lathe
Schönes Video! 👍 Als Ergänzung zu euren sehr gut sortierten Playlisten kann ich euch noch Ben Orford empfehlen. Hat einiges zur Grünholzbearbeitung gefilmt, ua Langholz- und Schüsseldrehen auf der Wippdrehbank.

Danke für den positiven Kommentar! Natürlich kennen wir die Grünholz-Videos von Ben Orford, besonders sein Langholzdrehen finde ich sehr beeindruckend und die Videos dazu sind auch für Anfänger sehr gut. Die Schüsseldreh-Videos waren ja die ersten "Tutorials" auf dem Gebiet, allerdings unterscheiden sie sich bezüglich Hakengeometrie und Arbeitsweise etwas von dem, was sich in der Schüsseldreh-Szene größtenteils durchgesetzt hat und was auch wir vertreten, nämlich Innenfase und offene, aggressiv wirkende Form. Haken mit Außenfase und Zwieschnitter folgen leichter dem Rohling und sind oft schwierig in der Handhabung, finde ich.

But where is the pole?
М-да.. Топор то не по руке,да и не колуном надо такие вещи обрабатывать..

Single beveled short handled axes like this are the traditional tool used for this kind of work by bowlturners, clogmakers, wheelwrights etc. It is a very good axe with ideal shape and weight.

On a side grain vessel like a bowl you turn from the bigger to the smaller diameter on the bowl side inside to cut with the grain. The cut on the core (from which the smaller bowl is made later) is against the grain, this can not be avoided and works well with the right tools and technique. Only inside end grain vessels (mugs/cups and some boxes) you cut from the smaller towards the bigger diameter.
