回覆 (48): Further notes on Watco.....
some better quality photo taken tonight, now i have enough strings to finish the "violin grille" for the left channel too. The color may not show up well enough, but the material is of purplish brown color, a nice complement to the woody look and feel

Hi Kris,  
 
Can you give some advice if I want to make my birch into a slightly orange natural hue like on this Klipsch La scala?  
 
Is it just a plain layer of lacquer? or Watco can do too?

回覆 (45): Further notes on Watco.....
I bought some elastic strings from a market near where I work (cwb) today, and they resemble very much the type of stuff used by Sonus Faber in their "violin strings" design grille. I used to have a pair of Guaneri Homage so I know.  
 
I wanted to visualise how my baffle would look like with these strings on, so i bought barely enough for one channel and worked like a factory lady tonight in my den. Here is the result, not bad! They are of purplish brown color.

Thanks Kris for your info and tips. I am quite sure when the time comes i would need to call for more assistance from you. Be ready..:P  
 
Some of you PM me for the shop info that I bought the european plywood from, i scanned the biz card and put it up here.  
 
they have different thickness version

The other effect goes well with Watco is call "stripping" (highlights on uneven grain), a technique we used to make cheap wood look vintage and expansive. The trick is to bring the wood grain down to it's natural uneven form (like a piece of drift wood from sea) by use of steal-brush, chisel or even sandblasting. You can do just a light touch to give the wood a little age, or a full strip down. This works primary on soft to medium wood only, not recommend on hard wood. Here are samples I did on cheap pine furniture 15 yrs ago.........

Welbone, to get the color value on the sample you posted before (see Saba below), the Walnut color instead of the natural be a safe bet , Watco offers 3 different choices in weight, medium or dark be fine.

Welborne, got your message. The Watco is a real EASY PIECY! From what I gathered, both daiwok and Vash tried it with more than agreeable results. Over the years, I've experimented with it on so many different types of wood, no mishaps. There're , however, few little tips that will enhance the outcome. Ask your guy to put a side some scrape pieces of the same wood from your Bastanis Atlas, I'll walk you through. Great fun!

I suspect the grille holders on top and bottom of the panels may be causing some diffraction issues. They are in for the look as a matching touch, but may take them off during serious listening.

have two tweeter holes on the main baffle. The smaller one is the permanent one for the Bastanis's orignal compression horn tweeter, the bigger one is to try out my favourite 13cm paper cone tweeters with alnico magnet, but i am not sure if i would ever put that on, so I asked my friend to cover the bigger holes with a piece of the same plywood crafted with a "treble clef" symbol, implying this is for tweeters.

The side board of the woofer is to come off when repair is needed. The screws for access to the woofer inside are hidden behind this baroque-motif board (held in place by small magnets). I like the copper metal studes around those curly pattern. There is a "Bass" clef symbol in the middle, implying this is the woofer.

some update...really late.  
 
The carpenter (well, window displayer to be more exact) has put the work on Bastanis aside as stepping into his busy season for christmas decoration, but still trying to squeeze some time out at my request.  
 
Some more photos. This is really the final stage, the only thing left would be mounting thd drivers, and staining the wood with Danish oil, the latter which I think would only be executed after a while.  
 
I have created a front grille system that is inspired (obviously) by Sonus Faber's violin string. I have drawn out a kind of curve for two pieces of plywood that resembles the shape of a grand piano. I mount them on top and bottom of the main baffle with the butterfly screws on the back that can easily come off. Will find a nice color (violet/puplish) thread for this grille.

i have two ideas swinging in my head:  
 
1) side boards with carved baroque curves pattern, stain to give contrast.  
 
2) dark leather mounted on sideboards, decorated by antique copper studs around the borders.

1) How about putting some ideas on creating contrast inside the cello's F-hole symbol by using a darker tone color.  
 
--------------  
you are really reading my mind. I have this exact idea to highlight the f-hole.  
 
I also have a few books on "french ironwork decorative pattern", very similar to what you have shown here. I like this pattern very much, perhaps an influence from our belgium jewellery designer. I am surrounded by baroque pattern every day here...

This is a sample of corbels suitable for your Bastanis Atlas. Make sure they are made of wood and glue them against the bottom corner.

Evening Welborne,  
 
 
Vash is correct on the shop, same one I gave daiwok. Ask for the lovely young lady Alky, she'll look after you well. The Watco product is really a no-brainer, unless you drink it, very little chance of screwing up. Should this be the final say, my pleasure to help anyway I can. But before you come to a decision, other little things:  
 
1) How about putting some ideas on creating contrast inside the cello's F-hole symbol by using a darker tone color. Or doing some inlay tricks with different wood veneers like the top of a Union square end-table. A dark Walnut burl (like they used for the dashboard of the old Rolls Silver Shadow) be wondeful. And if you want to be really BAD, apply the same inlay to the right side of the dipole woofer bin (inside the sunken surface).  
 
2) From the side view, noticed 2 pieces of rectangle plywood boards are holding up the baffle on each bin, a fun way to jazz it up is by adding a pair of antique wood corbels (upside down) at the top edge of those boards sitting against the baffle. It'll extend the flow of the "curves" from the cello's F-hole symbol to the whole piece. Be gorgeous!

HI Kris,  
 
I did not know you had so much experience in restoring heritage buildling...wow! x 3  
 
I know about the Danish Oil from a few years back and I bought one can but i forgot where i got it from. Perhaps...Temple Street Yau Ma Tei if my memory serve me right. That was the time when I first met Daiwok when I sold him a pair of Coral Beta blh box made from the same type of plywood. Please let me know where i can get those again.  
 
Honestly speaking, as creative as I can be with my brain, I lack confidence in doing anything with my pair of hands. I am afraid of screwing up my baffles with my clumpsy hands and a can of danish oil.....  
 
Perhaps you can give me some consultation

Morning gents.  
 
 
 
Welborne, enjoyed immensely in your diary on the Bastanis Atlas project, your conviction is inspirational. Couple points on finishing may be of some assistance:  
 
1) Unprotected plywood generally don't rest well under HK humidity, and will degenerate the resonance of the cabinet. It is of paramount importance to seal off the air from entering the ply - regular stains are unreliable (one of the main reasons why the color of most clear coat stains often turned yellow is because of the moisture entering into the wood fiber). In the old days when I was restoring heritage houses, the one product that impresses me most over the years is the "Watco Stain" - a penetrating oil that soaks into the wood and seals from within; will not crack, chip or peel. Extremely easy to apply, can be used as the final coat, or as base before applying further coats of "clear and wax" for a more sophisticated antique effect. Almost idiot proofed with no chance of 'fuck-ups', produces a warm, natural hand-rubbed appearance. Not too easy to find in HK, got the contact for you if needed, comes in natural and a dark walnut color. Same advice I gave to Bobby Chan on his ply-horn project and most recently, daiwok with his Saba.  
 
2) The other option is the old Chinese hand rubbed lacquer used on Chinese antiques, also a penetrating agent that soaks into the wood and protects from within, double sealed from the outside too. Takes about 10 to 20 layers to get the job done right. The good thing about this is that you can play with your creativity on color and contrast. On that note, imperfection is perfection. The only trouble is only a hand full of guys that qualify for the job and will cost you shit-load more than a can of Watco.  
 
Again Coleman, congrats!

this diy (i doubt) reso cabinet is really stunning. I like the use of the purplish violet fabric behind the two "f-hole". the color of the fabric must have been deeply inspired by the same fabric color found in most violin/cello storage case.  
 
The shape of the front and side baffles which also form the supporting legs has its root in "violin bridge", the small piece of wood supporting the 4 strings just above the tailpiece. A nice touch.

One of the side boards of the z-frame dipole bass bin is to be removable, as can be seen from this angle to gain access to the woofer inside in case of repair needed. The board will be where my further creativity lands upon. Would CNC some baroque period pattern.

the opening for the two 12" widebanders have been machined to give a 45" degree bevelling according to the original plan. The layering of the finland woodboard are the sexiest thing to touch and see of this project.
