Information about a Hinawajyu Bajyou-Tanzutsu

[Gilles Lavandera]

Hello friends, 

 

Allow me to introduce myself Gilles Lavandera. I am a French craftsman specialized in the making of functional miniature weapons.

Here is my website > https://www.atelierarmesminiatures.com/

And my YouTube channel > https://www.youtube.com/channel/UCLDdQQLQ6fDK_n2oUqtgE2g
I am making a Hinawajyu Bajyou-Tanzutsu, spelling found on the Japanese website, is it the right one ? I saw that it was often written "Bajo-zutsu", abbreviation ?

This 1/3 scale replica will fire .177 caliber pellets. It will be exactly the same as the following model > http://world.seiyudo.com/product/gu-010122/

Reading your posts, it is surely a modified weapon. The belt clip and barrel band are extremely rare on this type of weapon.

I think this gun received a replacement barrel. The pins and clevises (filed) on the barrel are missing but the holes are present on the stock.

The thin front brass barrel band holds the barrel (not very mechanical). If there is among you people who can give me information on this weapon any help is welcome.

I have a lot of nice pictures from the Seiyudo website. They allow me to have a precise idea of the dimensions of the parts with a scale ratio.

 

On the other hand, I am in the complete blur on the lock mechanism. I'm going to make a simple system like on the attached picture.

I also have many questions about the pan, was it fixed by dovetail. The stock seems to be split on the whole length of the ramrod!

How did the craftsman make such a thin slit? Does the ramrod force its way into the slot and spread the sides of the stock or is the slot glued?

You see my questions are numerous because I try to make miniatures as close as possible to reality.

 

To give you an idea of my work the steel barrel 52100 is bored (for convenience .177 lead pellets) precisely to 4,5 mm = 13,5 mm in scale 1 (4 monme).

According to the description Seiyudo site, the real caliber was 3.5 monme (13.2 mm). It will receive as on the photographs an inlay of brass and copper at the level of the muzzle.

To make this 4-wire braid, I watched tutorials of girls making bracelets!

Once braided, stretched, flattened and inserted into the snout, this 0.6 mm wide inlay will receive a layer of protective lacquer like the original Bajo-zutsu ...

 

I'm a bit crazy it seems! Thanks for your help Gilles

Hi Gilles 

Amazing project!

The shortest ones were called 短筒Tanzutsu, for wearing and carrying by your side. (Like the one above)

馬上筒 Bajō-zutsu were a short/medium length carbine for horseback, not as long as a normal Gunyōzutsu army long gun.

[Gilles Lavandera]

Merci pour les précisions Bugyotsuji, 45,3 de long et 25,7 cm de canon, c'est ni long, ni court. C'est peut-être pourquoi Seiyudo l'appelle "Bajyou-Tanzutsu" !

Je vois que tu résides au Japon et je me pose cette question.

Dois-je traduire mes réponses en Anglais ou je peux directement écrire en Français ?

Car ta réponse apparait pour moi directement en Français sur ma page. 

Le forum intègre-t-il un traducteur automatique ?

[Bugyotsuji]

There are smaller ones of course but that one is a Tanzutsu. The police in Japan today do not like the word Tanzutsu, so sometimes it is safer to say Bajōzutsu. (Most people do not know where these definitions cross over.)

 

I can understand your French, no problem. If this site does not have a translation facility, perhaps you could find one on the web… translate and then post here(?)

[Brian]

Beautiful work! As a lover of miniatures, I love these. Your work is amazing.
Piers will correct me if I am wrong, but I want to point out that the Hinawajyu/Bajyou/Tanzutsu are still Tanegashima/Teppo, just of a different style. So they could all fall under the same classification and are essentially made the same. Just method of carry/use differ.
It's like a carbine/pistol/rifle classification.
If I win the lottery, one of your products will be way up there to acquire.

Il y en a bien sûr de plus petits mais celui-là est un Tanzutsu. La police au Japon aujourd'hui n'aime pas le mot Tanzutsu, il est donc parfois plus sûr de dire Bajōzutsu. (La plupart des gens ne savent pas où ces définitions se croisent.)

 

Je peux comprendre votre français, pas de problème. Si ce site ne dispose pas d'un outil de traduction, peut-être pourriez-vous en trouver un sur le Web… traduisez puis publiez ici (?)

 

Merci Piers, si tu me permets de t'appeler par ton prénom, c'est plus pratique et court que Bugyotsuji, mon prénom est Gilles.

 

Je comprends mieux, pour moi aussi il s'agissait d'un "Tanzutsu" par la taille. Merci pour l'info sur la police, je nommerai mes créations Bajözutsu. J'aimerai tant avoir un client Japonais, j'ai eu un Coréen du Sud en 2020.

 

Je viens de lire la réponse de Brian qui est Administrateur et réside en Afrique du Sud. La communauté du forum est éclectique et répandue à travers le monde.

 

Je pensais que le forum était principalement lu et suivi par des passionnés Japonais. Je ne veux pas m'isoler en écrivant en Français je vais employer l'Anglais.

 

A très bientôt Gilles.

Beau travail! En tant qu'amateur de miniatures, j'adore celles-ci. Votre travail est incroyable.
Piers me corrigera si je me trompe, mais je tiens à préciser que les Hinawajyu/Bajyou/Tanzutsu sont toujours des Tanegashima/Teppo, juste d'un style différent. Ainsi, ils pourraient tous tomber sous la même classification et sont essentiellement fabriqués de la même manière. Seule la méthode de transport/d'utilisation diffère.
C'est comme une classification carabine/pistolet/carabine.
Si je gagne à la loterie, un de vos produits sera là-haut à acquérir.

 

Thank you very much for your compliments on my work Brian.
I would be delighted if you could one day afford one of my creations without having to win the lottery. They are certainly expensive but not overpriced.

For a Bajözutsu like the one in this project, I have at least 300 hours (2 month) of work (research, plan, manufacture of special tools, etc.).

At the minimum Australian hourly cost, this Bajözutsu would be worth AUD$ 6300 = 4300€.

2000€ is a reasonable price for work close to jewelery and to own a unique example in the world. You do not think ? 

I know what it's like not to have "big money". I offer all my customers payments over several months by Paypal transfer.

For example 2000€/6 = 333€ or AUD$ 486 per month.

Our world is far from perfect. I like to make sure that the exclusivity of a unique handmade object is accessible to everyone.

Gilles,
Oh, no worries. Your work is not expensive at all. I follow all the major miniature firearm makers, and your work is very well priced.
What I mean about needing to win the lottery is that I am unfortunately in South Africa.... about 18 of our Rands to ONE Euro.
It's not your work that is expensive, it is our currency that is worthless. It prohibits much of the good things in life. Didn't mean to make it seem I was commenting on the price.
At an hourly rate, it is a steal. Looking forward to watching your new projects.

Gilles,
Oh, pas de soucis. Votre travail n'est pas cher du tout. Je suis tous les principaux fabricants d'armes à feu miniatures, et votre travail est très bon marché.
Ce que je veux dire par avoir besoin de gagner à la loterie, c'est que je suis malheureusement en Afrique du Sud... environ 18 de nos rands pour UN euro.
Ce n'est pas votre travail qui coûte cher, c'est notre monnaie qui ne vaut rien. Il interdit une grande partie des bonnes choses de la vie. Je ne voulais pas faire croire que je commentais le prix.
Au tarif horaire, c'est une aubaine. Hâte de voir vos nouveaux projets.

 

A thousand apologies Brian! I did read South Africa and looked at the cost of the Australian dollar.

I'm a bit tired ! The euro is a strong currency, it is a real handicap for the exchange rate with many countries.

I am confused by my mistake. Gilles

Hi friends, 

 

I was hoping to have precise technical information on this Bajojutsu, but I see that no one has answered.
Looks like there was a scholar on the Forum "Donald Watson" I believe, His avatar is Stan Laurel.
In the absence of advice, I made the following technical choices:
I mounted the flash pan (hizara) on a dovetail as well as the sights.
The sealing of the flash pan (this miniature will fire) is made by a series of 1 mm holes filled with tin. After heating with a blowtorch, the tin melts and fills the intertwinings.
The barrel protector (ama-ooi) is mounted as originally with a wedge (ama-ooi kusabi). The sloping groove is 0.5 mm wide.

The barrel eyelets are also brazed with tin, then filed on the barrel to the correct size.
For the barrel signature (Mei) I engraved my initials G (Gilles) L (Lavandera) in Rõmaji letter (Japanese Latin alphabet).
It was quite hard to do with a 0.2 mm chisel. The barrel is in Stub 100C6 (52100) steel. I hope I haven't made a mistake, this is my first engraving in Japanese.
Finally, I remember reading a post by Donald who explained that the "real" pan cover pins (hibuta) were drilled right through and held together by a thread.

Mine is 6 x 1.5 x 1 mm the partial bore of the ends is 0.6 mm, the passage of the locking brass wire 0.25 mm. The brass wire is 0.15 mm.
I hope you will find the whole coherent because it took me more than 100 hours of work to get there. I redid the pan cover, the first one not compliant and it broke.
Here is a series of Goopics links that will allow you to follow the manufacture. The first link is the start of production, the last link the last works.

Hi friends,

 

Very few people have reacted and responded to this post. I made technical decisions without certainty of authenticity.

Nevertheless, I think I stayed very close to the original model and the spirit of a Hinawajyu Bajyou-Tanzutsu of the EDO period.

I made a cherry wood stand for the presentation of the Tanzutsu and its 2 powder flasks. 

This model went to join its owner in Canada. It is accompanied by 2 primitive arquebuses at 1:6 scale.

Here are many links to pictures of the making of this model while waiting for the videos. The precision and the shooting power of the Bajo-zutsu (forgive this ellipse) are incredible !

 

Gilles

Fantastic work all round, Gilles. Wonderful. 

 

(The larger coarse powder flask is a blend of two types, though, which is creative! Can you show the smaller priming powder flask in more detail?)

[Brian]

Fantastic work. I love it!

[Gilles Lavandera]

Bonjour Piers,
Merci pour votre gentil compliment sur mon travail. Cet ensemble a demandé plus de 350 heures de travail (450 avec les 2 autres arquebuses).

Oui le "gros flacon" (seulement 108 mm de diamètre à l'échelle 1:1) s'inspire de nombreuses photos de flacons à poudre japonais vus sur le net (photos jointes).

Le petit flacon à poudre est fabriqué à partir du bout de corne de cerf. Son originalité consiste en ce que le capuchon est muni d'un clou en laiton qui empêche l'obstruction du trou par la poudre noire.

Vous avez toutes les photos détaillées dans les liens Goopics et surtout celle-ci.

Cordialement Gilles

Travail fantastique. Je l'aime!

Thank you very much my dear Brian,

 

I hope with all my heart that you can one day offer you one of my miniatures.

On my side, the lack of new orders forces me to take another job to live.

While waiting for the editing of the YouTube videos (I'm in the process of doing it) here are some test shots taken with my smartphone (for the sound recording).

The power and precision are really incredible! The Tanzutsu pierces 2 1.5 liter bottles filled with water or penetrates 12mm of pine plywood with only 7mm of black powder.

The bullet is a 4.5 mm round lead and 0.53 grams! The tests were carried out before the finishing touches (barrel bluing, decorations, wood varnish). 

Regards Gilles

Superbe! ❤️ 

Merci beaucoup Piers, mon client Canadien est ravi. Comme je le dit souvent, l'éclairage artificiel de mon atelier (tube fluorescent) et le zoom macro écrasent les vraies couleurs et intensifient les défauts.

Sur les 2 photos jointes on pourrait se dire il y a des défauts. Mais quand on sait que la tresse bicolore à 4 fils fait 0,6 mm de large et que le guidon laiton fait 1,3 x 1,5 x 0,5 mm, tout est relatif.

En lumière naturelle, les miniatures sont bien plus belles et rien ne remplace le toucher pour apprécier certains détails, la finesse du bois, le fonctionnement d'un mécanisme ou la puissance et la précision d'un tir !
