Prego l'arciere che mi ha mandato delle mail la settimana prima di Pasqua 2019 di mettersi di nuovo in contatto con me perchè per errore ho cancellato tutte le corrispondenze.
Comunque il foglio di istruzioni dei limbs Super Feel l'ho trovato e pubblicato in questa pagina alla voce "documentazioni".
Grazie

                            • Questo è un Interessante articolo sulle sconosciute ultime produzioni prima del tracollo, archi speciali in esemplare unico per Sebastien Flute, considerazioni strategiche e commerciali piuttosto amare ecc. ecc. (E' in giapponese quindi anche google fa quello che può, qualcuno può riaggiustare la traduzione? link)
                            • Interesting thread about last unknown Yamaha productions before the sad stop, is in japanese... link , if someone can adjust translation thats will be appreciate.

                            Article resume. Courtesy by John Whowell
                            The article is written by Kawakami Genichi, more than 40 years president of yamaha.
                            he says by the time the super feel was thought of, yamaha was in a bad way.
                            all the good engineers had left and the sales were really low, for 2 reasons.
                            1 a lot of people had turned to compound bows, and 2 the yamaha bows were too heavy for japanese.
                            so the super feel was supposed to fix that, but instead turned out to be even heavier.
                            because it was weaker, they had to make it fatter so it wouldn't break in half.
                            the Sebastian bow he says looks like a super feel 2 but isn't, it's aluminum, and was hand crafted, no mould, and not drop forged at all.
                            He says the super feel 2 is the worst bow, and don't pay a lot for them. they are scarce, but they're not a good bow.

                            Scritto dall'autorevole Kawakami san (1912-2002) presidente di YAMAHA per oltre 40 anni.  Parla fra l'altro degli archi speciali produtti per Sebastien Flute nell'epoca post Eolla (e per qualche altro atleta) che niente avevano a che vedere con il prodotto di serie che era stato rifiutato dai testimonial perchè ritenuto pessimo.
                            Ci sono anche pesanti critiche rivolte alla direzione commerciale che ha privilegiato il profitto alla prestazione ed alla ricerca, generando di fatto dei prodotti (FF II) fallimentari dal punto di vista delle prestazioni e delle vendite.
                            Commento al commento: semplicemente ridicola (oltrechè tipcamente commerciale e GIAPPONESE) la decisone di produrre per motivi di rispamio di costi solo risers DESTRI e CORTI a partire dal Feel Forged.

                            LONG SFF2 riser
                            From one of our best contributors: Jim Spencer

                            Here 'tis photo's as talked with John Yesterday about of the mythical never produced (???)  LONG SFF2 riser.
                            I had an enquiry about Super  ceramic limbs lighter than 40# from a person I think from Holland, as  soon as he said he had an SFF2 riser I assumed he needed long limbs, so I  told him the tale of woe relating to their availability.  (it's a no....)
                            He insisted he had a 65 cm riser, so I asked for Pictures, and TA DAH !!!
                            Although he uses a 30cm ruler  showing top half then bottom half of bow, when I put a 30cm ruler  against my SFF2 short riser, it goes to the pivot point on the grip from  both directions, where as in his photo's the ruler  does not quite get to the pivot point, thus proving his riser is indeed  a couple of cm longer on each half of the bow therefore 65cm.  Hence as  he is asking for Medium Limbs, I may be able to help him, but what a  waste, the only person I have found with an  SFF LONG riser , and he only needs a 68" bow !!!!

                            Learn something every day.........
                            I want one. . . .  .  .  .  .

                            Broken YTSL2
                            From our friend John Mooney.  lunartech@ntlworld.com

                            Bruno . I am sorry I only speak english, I have visited your website  before and found it interesting. Earlier this year I was shooting my  YTSL2 when it snapped in half due to metal fatigue. Now I have other  more modern bows but I like the feel of my Yamaha. so I decided to see  if it could be fixed. First I cleaned up everything including all paint  back to bare magnesium , I drilled through above the stabiliser bush  down through the break into the lower section  I tapped M5 the lower  section and recessed the head of a 100mm long M5 bolt in the upper  section. I applied a  very strong automotive resin (JB Weld)  and bolted  the two parts together. Next I made two steel plates which i Shaped to  the form of the bow. when sure they would fit snug I clamped them on and  drilled through in 5 places 2.5mm and tapped the holes M3  I again  applied JB Weld and screwed the plates in place and smoothed off the  resin that was squeezed out. When set I smoothed off the rough edges and  gave it a coat of primer and a quick coat of spray paint  I am  currently using 39# medium carbon ex limbs . I decided to try it out  after shooting a round at my local club and had enough time to shoot 24  arrows through it with no problems and there was no signs of the break  moving or cracking at all pleas see pictures I have decided to send you  this as it may help someone who has suffered a similar loss and would  also like to try a repair... what is there to lose?

                            I  am currently on holiday and not at home  so I will not be on that email  address for another week  but when I get home I have the instruction  manual for the standard Yamaha pressure button which I will scan and  send to you for your archives. I hope you liked my repair story on my  YTSL2

                            Thanks John, sorry for very late publish. Bruno

                            YB66 - YG68
                            From one of our friends: Glen Bowley gbowley2014@gmail.com

                            Bruno, I tried to sign on the forum but could not.  I have two,  "vintage" Yamaha one piece target bows, a YB66 and a YG68 that were  bought, used in the mid 1970's.

                            I acquired these two Yamaha one piece bows in the  mid-1970's when I was in college, they were both used but not very old  at the time.  I suspect they were made in the late 1960's or early  1970's but that is an estimate on my part.

                            They  could be bought quite economically in those days because the market  here was going over to compounds and the target shooters were switching  to take downs.  I have always liked one piece bows, so this worked out  well for me.

                            They are;
                            1.) Yamaha YB66 marked 25# (it has red glass, as can be seen)
                            2.) Yamaha YG68 marked 35#

                            I  been involved, off and on, with archery since 1970 and have recently  taken it up in the spring of 2018 as a main retirement activity.  My  shooting focuses on recreational and 3D (WA Rules Instinctive for me),  so I shoot the YG68 bare, as shown in the picture.
                            The YB66 must be on the light end of the scale because it draws 28# at my 30" draw length, the YG68 measures 40# at 30".
                            These bows have always been stored properly and strung with a proper stringer.  They are only used with Dacron strings.
                            I  am shopping for another bow, but these Yamaha's shoot very well.  If  Yamaha still made bows like the YG68, I would buy another one.
                            Regards
                            Glen Bowley

                            Hi Glenn
                            Late but finally i can put you bows on the site.
                            Thanks
                            Kind regards

                            Dear Bruno,
                            Came across your excellent website quite by chance.
                            Like you, I have an interest in Yamaha Archery.
                            Over the years i have bought bows and parts on Ebay and think I might have an example of all their bows now.
                            Difficult to know as I have never been able to get a definitive answer from Yamaha Japan. your list, however, looks comprehensive.
                            Let me know if you want to liaise.
                            Happy New Year,
                            Ken Newton

                            A rare YC (i suppose) unfortunately has broken limbs

                            Here are some photos.
                            In photo #4, the knobs I can not free. In photo #5 you can see how the blade is broken.
                            If I could free the knobs, I think I could replace the blades, but maybe it is not even worth it...
                            Thank you again for the advice.
                            Kind regards,

                            I also have an SFF and SFF2,  which aren’t in that picture...
                            I attach some images of earlier bows - YA, YB and YC.
                            The  singular image is of a bow with no identification mark but certainly a  Yamaha with GRP reinforcement on BOTH  sides. Do you have any idea what  it might be?
