SKERVESEN Guitars (Poland Inside!!!)

Arg, ça fait envie !!!!!

Mon build doit commencer ce mois ci !!

PS : je n'ai pas oublié pour les photos de ma 7 j'espère pouvoir ce week end

Pour moi il l'est

De nos jours, le tout fait main est une piètre excuse pour pas se mettre derrière un PC, sauf boutique full custom.. mais les vik blackmachine et compagnie, on y gagne rien, et on a aucune preuve que tout est fait main, c'est la parole du luthier, que vaut-elle ?

Tu peux pas dire que que ceux qui ne travaille qu'à la main sont des flemmards de pas se mettre derrière un PC, une CNC c'est déjà un sacré investissement, faut être calé en programmation et on peut pas en vouloir à certains de travailler à l'ancienne.

A ce sujet je suis tombé sur l'explication d'un luthier qui utilise une CNC, au moins c'est clair

First off, there is no shop, large or small, that is entirely CNC. It does not exist. I think most individuals would be surprised by what a guitar component looks like when it comes off a CNC. It is no where near complete, there is still plenty of hand sanding, fitting, etc.

Here's a break down of what I do with the CNC and "by hand".

CNC:
Fretboards - you asked "why
they've gone to the CNC and what aspect of things is better". The fretboard is so brutally important that it is ideal for CNC accuracy. I perimeter, slot, radius, and rout for inlays all in one set-up on the CNC. Than insures spot-on fret slot placement (VERY important to the quality of the guitar), consistent radii including compound radiusing, and inlays that are very tight and free of sloppy filler/gaps.
Total time on the CNC: 20 minutes

Necks - Once the blank has been bandsawn ("by hand") to an oversized shape the CNC will machine the neck carve, perimeter the neck and heel, shape the headstock, drill for tuners, rout for truss rod and rout for logo & purfling. This is done through 6 different set-ups.
Total time on the CNC: 1 hour, 45 minutes.

Bodies - The CNC performs all cavity routing (top & back), neck pocket routing, perimeter, top carve, and bridge location holes. On a pivot style trem, such as a PRS trem, the location of those 6 holes must be perfectly inline to prevent binding of the trem during use.
Total time on the CNC for a body with carve top: 3 hours

Inlays - Production inlays, such as my Firesuns and "T" logo, are cut on the CNC for a perfect fit into the routes on the fretboard and headstock. I also "rip" my purfling strips on the CNC too.
Total time for one guitar's worth: 15 minutes

Components - I machine my own 1-pc. brass tremolos, pickup covers and rings, knobs, back plates, truss rod covers, and jack plates.
Total time worth: Approx: 10 hours.
Granted, all of these parts are "custom" for my guitars exclusively. I could purchase all of these parts from guitar supply shops but prefer to make my own.

None of the above times include any programming, set-up or material preparation...all of which are done "by hand".

_____________________

"By hand"
This term, I assume, includes feeding or pushing the component through a power tool such as a planer, jointer, drum sander, bandsaw etc.

Fretboards:
Pre CNC: The wood is bandsawn to an oversize thickness and feed through a drum sander to flatten.

Post CNC - The fretboard needs to:
Have the side dots drilled and glued in.
Inlays and purfling glued in.
Glue the board to the neck blank.
Level and true the board.
Fret and fretdress.
Total time "by hand": 13 hours for the above operations. My fret preparation (cutting to length, nipping the tang, grinding the tang), fret installation and dress is a total of 6 hours alone...no CNC for any of those operations.

Necks:
Pre CNC:
The wood is milled and rough cut to shape, using tracing templates, on a table saw and bandsaw before it gets to the CNC.
Post CNC:
Install the truss rod and filler strip,
blend the neck into the fretboard,
inlay logo and purfling,
final shape the neck carve to spec using rasps, spindle sanders and lots of elbow grease sanding then sanding some more,
gluing the neck into the body.
Total time "by hand": 8-10 hours easily.

Body:
Pre CNC:
Split top, joint edges, bookmatch glue together, sand to thickness.
Mill/sand body to thickness.
Locate and glue top to body spread then sand and drill locating hole for the CNC.
Post CNC:
Inlay purfling.
Drill for controls, side jack, wiring channels.
Radius back edge on router table.
SAND from 150 grit to 320/400
Total time "by hand": 10-15 hours depending on the wood species.

Paint:
Prep, mask off, stain, seal, color, top coat, lots of sanding in between, lots of sanding after, buffing...the list goes on. No CNC for these ops.
Total time "by hand": 28 hours if all goes right the first time...it never does.

Assembly:
Installation of components (tuners, pickups, bridge, etc), wiring, cutting the nut, set up.
Total time "by hand": 6-8 hours

The above is only visually productive acts, not including ordering wood and components, e-mails, shipping, and just plain running the business.

_______

So, if we deduct the custom components and use off the shelf bridges, pickup rings, etc. The average total time is:
CNC: 5 hours, 20 minutes.
"By hand": 69 hours, 30 minutes.

I consider my shop to be fairly state of the art, I have a large HAAS CNC for the woodwork, and 2 smaller CNCs for the pearl inlay work. The only additional automated CNC-type machinery would be a Plek and a robotic buffer. I could see that only reducing the "by hand" total by a couple/few hours at most.

Not mentioned would be a custom one-off inlay that I, or my father, would do "by hand" with a jeweler's saw and a mini router. The time spent on that could be from 45 minutes to 100s of hours depending on the design.


However small in comparison those 5 hours, 20 minutes seem...they are VERY important to the outcome of the guitar. Accuracy and consistancy are unmatched. There are features, such as my double offset purfling, that just can't physically be done by hand. Fretslots accurate to within .0005" of an inch...heck, the wood will expand or contract more than that by the time I turn the lights off in the shop at the end of the day...but it's good to know they are as accurate as can be.
Inlays that are gap free and clean are important to me. I'm not a fan of filler and I don't want that to be a part of my product. Even with hand cut and routed inlays, I feel we are one of the best at making them tight and clean.

Can I build a guitar with out a CNC, sure.
WOULD I now if I didn't have one...I doubt it, because I would always feel the guitar isn't as good as it can be WITH the help of a CNC.
There you have one take on it from a CNC builder.

Interessant tout ca ! Merci!

au moins c'est clair !

Il dit pas tout le temps qu'il gagne à pas se farcir le boulot du CNC au même degré de précision et il serait plus honnête de pas compter le temps de collage, mais bon, faut bien qu'il se vende un peu. Bizarre qu'il ne programme pas le profil du manche, étant donné la rigidité de ses modèles.

Une CNC ne coûte pas tellement cher, y a des premiers prix sous 3K qui font le boulot, bien sûr c'est pas de la 5D au micron avec changement de fraise à la volée. Quant à la "programmation", c'est pas si difficile, juste un investissement. (et en partant du principe qu'un luthier désirable a une bonne "intelligence spatiale"..) Pour un Ron Thorn c'est très profitable.. Je pense qu'ils sont nombreux à jouer sur l'ignorance des clients et les mythes du CNC pour gonfler la note. Personne n'a envie d'avouer que c'est plus la mer à boire que ce fut. Les logiciels sont de plus en plus faciles, et la techno de moins en moins chère..

la raptor 003 est à nouveau à vendre







Ne pas craquer, ne pas craquer !

a quel tarif, si c'est pas indiscret ?

le gars en veut 1600 € + fdp

c'est raisonnable

bon prix!

je profite puisque ici on est un peu une petite communauté de geek de belle guitares de poster la video Teaser de mon groupe pour trouver un chanteur, c'est fait avec une mayones et l'axefx2 en autres. et joyeux Noël!! normalement ma 7 cordes de luthier arrive fin janvier mais je préfère ne pas en dire plus avant de l'avoir

Très bien Vaihalen, ça le fait.

merci mec!

bien trop technique pour moi mais y'a du niveau

Super ton groupe VAiHalen ! J'aime beaucoup ce mix de styles, ça rend très bien.

Dites-moi, est-ce que vous connaissez des revendeurs français de mayones où l'on pourrait en commander?

Amps guitar à Cambrai est l'officiel.

merci Aldras!

oui c'est Ampsguitar shop le revendeur, c'est sympathique et j'ai commandé la mienne par son intermédiaire.
