    Wow man! :eek: Killer veneer you got there. Kinda makes me wish I'd went that route on mine.

    I've been looking at some of the same stuff... But I can't tell you how nervous veneer makes me! Is raw veneer from a fellow on eBay really an OK way to go for one's first attempt?! I mean, yours certainly turned out pretty nice...

    Damn! You're bookmatching it and everything. You sure this isn't your first time?

    I did contact cement per LouC's tutorial. There were definitely some tense moments as the cement grabbed and couldn't be repositioned at all, but it worked out.

    Can I ask what seller you used on eBay? I've seen a few, all of whom look to offer some promising books of veneer at decent prices.

    I also bought some Walnut from a "greatdane6" and was OK with it but a little less happy because there were some pretty significant long cracks that were not disclosed. It's usable, though, and was cheap.

    Try Rosebud Veneer. All raw veneer, but good prices and accurate descriptions. I've bought several lots from them.

    Purple die sounds good. I see some natural purple hues in my batch of veneer already. Such an interesting wood to look at.

    Good progress over the weekend. I'm pretty happy with how the veneer is going, after a rough start with edge tearout and some cracking during rough cuts with a razor knife. After some practice runs, I settled on a laminate trimmer bit for all the flush cutting instead of a bearing bit.

    All these shots are before any sanding (beyond a quick wipe over the flushed edges), sealing or finishing.

    Getting close! I just have to flush trim the backs, glue on the tops, then start thinking about finishes.

    Finally an update. The veneer decision has been really tough - I've only used PSA in the past, and wanted to learn how to work with raw veneers, but at the same time not spend a ton of money and mess things up.

    I bought three cheap lots from ebay just to practice a bit and see how they look in real life: aromatic camphor (beautiful, but very wavy and some cracks, probably better for later when I have more experience with this stuff), walnut (nice for later but too dark for these), and finally 11 sequential sheets of bubinga. The bubinga is beautiful. Subtle patterns and different purplish and red color hues inside the swirls.

    The sheets are long enough to cover the entire vertical sides but not quite wide enough to do the whole depth of the speaker. I'm OK with this as long as I get good seams. Getting larger pieces looks like it would be cost prohibitive.

    The first thing I did, being an amateur at this, was to get the sheets all out of order and then spend about an hour trying to get them back in sequence. :rolleyes:

    I'm using LouC's veneering guide with contact cement. It's a LOT harder to do than PSA, and the huge cabinet size isn't helping! I've got all the sides of both boxes done now, and they look pretty good. I'm still not sure if I will do contrasting wood on the baffles.

    Also bought some dewaxed shellac, thinking it would be a good finish without darkening too much. I just want to pop the grain out, not color the wood. Is there anything better to use? I've tried a sample but it seems too dark. Maybe just poly?

    Cabinets flush-trimmed, sanded and filled:

    Good grain and colors:



    It's been over 100 degrees here so I moved inside:

    That's exactly what happened! "I'll just break them in for a few hours then go veneer shopping...." Then family swimming lessons, karate classes, cub scouts, and of course work took over.

    I've been listening to them daily and have discovered what "big speakers" sound like all over again. My room has a nasty ~45Hz null, which has improved very much by having the two big Peerless woofers spread out. That frequency was just soaked up by one sub's output.

    Anyway here's my progress:

    I have the circular grilles almost done (covered in black cloth with magnets).

    Just bid this morning on some Bubinga and Camphor veneers on eBay so we'll see what happens. I'm looking for a burl type with lots of character that isn't super dark like walnut. The "Hoss" design is an example of the look I would like to achieve. Hopefully this will not turn out as a case of "aim high and you're bound to be disappointed." :D

    Thanks for all the support guys - it does help keep me going.

    These are looking great so far -- looking forward to seeing the veneer and your listening impressions!

    Really nice work. I can't believe you got that done with 3 little helpers, I get nothing done with only 2.

    Can't wait to see your final product and listening impression. I think of pair of these bad boys in the basement would be a good future project.

    Well it's been a while since I've had time to work on these, but I put a couple hours in yesterday. After much thought, I decided to go ahead with flush trimming. I will most likely do a roundover on the top and bottom horizontal edges, which opens up the possibility of a nice run of veneer spanning from one side, across the top, all the way over to the other side. Then the front baffle will have a separate veneer piece, probably with some contrasting strips.

    I just don't think I'm up to dealing with the compound curve issue, and I don't want to risk routing a groove in the nice laminated sides to insert a solid wood strip. A man's gotta know his limitations. :o

    My 2" wedge foam arrived last night, and the cabinets are lined. I did add a couple more braces after knocking on the cabinets with my knuckles. Also got all the HDF pieces that will be used to create the driver and port grills routed and sanded.

    Now that the cabinets are lined and the drivers are broken in, I can say that I really like the sound of these speakers. They are not as "technical" as the Statement Monitors with their ribbon tweeter, but they really do a good job making less-than-perfect recordings sound good. They are not quite as detailed, but not harsh at all. The bass and midrange vocals are punchy and just fun to listen to. There's absolutely no need for a sub when I'm listening to 2-channel music on these, and they will go lounder than I could ever possibly want to go in a 22x30' listening space. :D

    All the pieces for the grill skeletons. The ones on the right are for a Nano Neo build that's waiting in the wings:



    Flush-trimmed cabinets:



    My team of highly-trained speaker building professionals. For some reason the cabinet sides look like they have flat spots in the pictures. In reality they are very consistently curved. Maybe the veneer will bring this out better:
