Baffle starting to take shape.

A lot more work to do. Hope the owner will appreciate the effort spent making this cabinet.

Another masterpiece in the making. Can't wait to see it finished.

Update lang sa AN project.

Some more details and pwede na isara ang cabinet. Had to put in place the double baffle and T-nuts next.

nice! If I may ask, paanong method mo sa veneering sir?

I noticed the box had veneer before the shaping of the trim pieces. Was the veneer applied after the basic box was made or as plywood sheets?

In the pictures, the veneer sample was warpy if you excuse the word. I thought they were bought flat. Is that how veneer is sold? Scary pala. Looks very fragile.

I believe sir Larry applied the veneer on the plywood first, prior to making the box (as seen in his previous posts). Galing ng craftsmanship, kasi kung hindi kasi marunong ang gagawa, e sisilip ang plywood layers or hindi exact fit. Kudos to the maker.

I think the veneer is a bit warpy because it is real wood veneer yata. Usually nga flat, sobrang thin siguro ang layer nito or walang sheet backing.

The veneer was applied to plywood pieces using a hot press machine. Yes warpy talaga and fragile ang wood veneer since less than a mm lang ang thickness nito. What you see in the pictures are double ply veneer applied to plywood. I was lucky to be working in an industrial facility where a veneering company is located.

If the cabinet is finished already, you will have a hard time veneering although doable naman applying veneer. We have done this when we refurbished a JBL paragon speaker pero mahirap. Rugby ang pwedeng pandikit.

May hot press machine pala, eto pa lang method na to sulit na para sa nagpagawa

Most real wood veneer is .6mm, sa western countries merong mga available na "paper backed" & double ply which I think is mas madaling i-apply.

What is the purpose of double ply veneer?

This build is really awesome and shows why such speakers are very expensive. Given the amount of work and in this heat, the craftsman deserves his pay.

I just worked on tiny bookshelf speakers and it felt like I was building a house. High respect to you guys tackling larger projects like RXV's.

Gino - from the interwebs:

2-ply or wood-on-wood veneer

Quote

Wood-on-wood, also known as "2-ply veneer" is two wood veneers permanently bonded together. The face veneer grain is perpendicular to the backer veneer which provides protection against bubbling which occurs when a veneer is improperly bonded to the substrate. This type of "crossband construction" allows the veneer to bend on moderate curves in the horizontal or vertical direction. The veneer used on the back side of a 2-ply veneer is often an imported hardwood of lesser value.

Sir Larry,

If I don't have access to a hot machine press & will do the veneering manually, how would you suggest I go about it?

Thanks!

Alam ko sir Deist, normal iron gamit e, may paper/cloth in between lang para hindi masunog ang veneer. Maybe sir Larry can chime in.

Veneering is definitely one of the skills that I will hope to learn in the future.

Timber,

May mga gumagawa ng guitars dito sa San Anton, Guagua. I have requested someone to ask one of the workers there what glue they are using and where they purchase. I will let you know if there is feedback already.

Depends on the condition of the veneer that you will buy. Meron kasi na halos flat na at walang mga bumps o bukol. If no special glue can be found, pwede na ang contact cement pero dapat yung malabnaw at madali ipahid. Apply evenly to both sides, making sure that walang magbubuo-buo na contact cement. Kung meron man, dapat alisin agad ang namuo kasi siguradong babakat sa ibabaw ng veneer yun pag na-flatten na. You can use wooden rollers katulad sa baking or kung wala kahit rubber slippers lang to flatten ung veneer na dinidikit mo making sure walang bubble sa loob. You can use plastic sheet on top of the veneer when doing the flattening so as not to damage the veneer.

Ang tricky part ay pag may mga bumps ang veneer na mabibili mo. What we do is to wipe the veneer with moist cloth, let it stand for a few minutes before applying contact cement. Dito medyo kailangan mo na i-press o daganan ng separate piece of plywood ang ginagawa mo. Suggestion ko practice muna sa maliliit na pieces. Ang dami kaya namin nadamaged nung unang gumagawa ng ganyan kaya practice lang.

Pag natuklasan ko kung ano pinangdidikit sa gitara, I will let you know. Definitely mas maganda ito.

My wonder adhesive for applying carpet liner on car speaker boxes was 3M Super 77. Wicked adhesion and no room for error. But i think the same thing can be said with two sided contact cement method. I was thinkin g of using this to apply veneer on my bookshelf DIY. But decided to cut my losses he he.

deist · « **Reply #1309 on:** May 29, 2015 at 03:00 PM »

^^ thanks for the very detailed response sir Larry, I agree with the guitar adhesive, wala pa akong nakitang umangat na veneer sa gitara. Kailangan malaman natin sekreto nyan

Got the foam from Sir Nelson for installation inside the cabinet.

Very nice vintage speakers you got there

I've always wondered how they would sound, since the design front cover is different from the usual designs..

Not vintage. May 3-4". May 8". I think galing sa mga busted speakers nila. But it's dirt cheap. Yun nakita kong 3" that looks like woofer sells for P60 only. Great for DIY projects if you initially don't want to spend much. Not sure kung new tweeters din for ambient sound like the topic discussed sa As audio thread. Hehe!
