Curved Volt 6's

With Erich temporarily shutting down the DIYSG site, I figured I better hurry up and get around to making rears. So now I'll have Curved Volt 6 bookshelfs to match my Curved Fronts

Materials: 3/4" MDF + 2 Layers per side of 1/8th Hardboard

Finish: Cherry Veneer with Mahogany Stain

Outer Measurements: 12 Tall X 8 Wide X 8 Deep

Internal volume: ~ .26 cubic feet (not including Woofer, brace, Port)

Port Size: .5 Tall X 4 Wide X 4.75 Deep (comes out to 9.5 Cubic Inches which is about the same as the kit's port. @mtg90 Said this should be fine)

Kits are ordered, but haven't arrived yet. Hopefully I can get the main parts cut up over the long weekend.

I just did some double checking of the port tuning, looks like it might come in a little low. I had assumed you were staying with 0.2 cuft. I would either cut the port down to 3.5" deep or make it 5" wide. Wider port has benefit of reducing port air velocity.

Hmmm... Just checked and if I go wider it would run into the curved walls before the port ended, so I think a shorter length is my only option.... Well that and the Golden ration of 6.5" is ~4"

Ha! My fronts were my first real woodworking project and I had a ton of help and fancy tools to learn with. Now I don't even have a table saw so this one will take a lot more patience and quadruple checking my measurements. I'll probably start making the dado router jig this afternoon.

Worked on them some today. Got the fronts and back cut out and their dados cut. Also got the top, bottom, and braces cut out (still need to cut out the middle part out of the braces though). Since I'm not using my buddies shop this time around and just using a circular saw, it took me a while to get the angle cut (20*) on the back panels. Lots of little nudges and test cuts.

To make the curved pieces, I had to rig something up with my sander. So I cut a slot out of my bench and then shimmed it up to 90*. After I rough cut with a jig saw, I just sanded it down nice and slow.

(No idea why some pictures are sideways or upside down???)














And this just my garage where Im doing it. I dont really even have light besides that one flood light. And my trusty TV tray for cutting

Bravo! This is my favorite kind of DIY. Don't have the tool....make one.

I'll have that same 5 channel setup eventually. Although I ordered the newer alchemy towers instead of your converted MTMs. the volts were out just a few days before I ordered so that'll have to wait. Mine won't be curved either. I imagine there is a build thread for those? I'll go look for it.

Great job so far! Your finished veneered MTM's are gorgeous so I'm happy to see your drawing from the same design. My wife saw this thread and said to me "You shouldn't have bought the flat packs (for the Vokt-10's)." HAHA. That's ok, I think all curved 1099's and curved SI 18's along the front are enough!
Keep up the good work, man!

Thanks @Samps ! This is definitly more challenging than when I used my buddies $75K Table saw, but it's more challenging and is pretty fun coming up with all the little jigs and what not.

@dtsdig , your curved 1099's were part of the motivation to get off my butt and get these done. That build is coming along stellar thus far. Tell your wife that while you may have flatpack rears, you at least have a curvy SI 18. My SI 18 is just in a big cube. I might rebuild it one of these days though...

Here is the sketchup file:

FYI, the speaker cut out is just for visual representation. I don't know what the exact cutout size is since my speakers aren't here yet.

Update!

Speaker kits finally got here today. Do we even need to talk about the impeccable packing anymore? I means besides the minor inconvenience of chasing my lady friend's cat all over the living room with some of the packing material, couldn't be happier.

Will probably start cutting the driver holes this weekend and trying to finish these guys up. Just picked a Sony VPL-HW40ES Projector, so I'm building the 102" screen tonight.




(yes, I know I need to sand and veneer the marty still :P)


(Just sitting on my lap about 30 seconds after I walked in the door )

That looks deeper than I thought it was. I was imagining the CD sitting flush. It's going to be tough to build shallow cabs for those unless you angle them. My wife is not going to be happy when I hang those suckers off the wall. But I'm gonna do it anyways. Looking forward to this build.

I really like your curved builds. I'm inspired to do a Cinema 8 curved and veneered like yours some day.

Thanks Michael. I'm hoping to get out to the garage tonight to work on the front baffles. I pretty much slacked off all weekend. Unfortunately, my time is going to be limited coming up very soon as one of our main client's busy season is VDay and have lots of traveling lined up. My Goal is to have these built, veneered, and stained (along with my minimarty) by the GoT season premier.

Holes for the drivers cut. Thank god I did a practice cut on a piece of scrap. I was off by almost 3/16 the first try. I really should look into a proper hole cutting jig soon.

Got them glued up last night. Was not as smooth as I had hoped it would go but should be ok. I have also just realized that I haven't cut the port opening yet.... whoops!

Got the slots cut out, ports made, and mounted in.





Also learned not to to jerry rig your router with clamps to the work bench as a make shift router table. Bad things happen.

Spoiler!

Ouch!

My worst accidents seem to come from the drill press, though I have had some close calls that could have gone much worse with the table saw and router table. All three are tools where you handle the material and the tool remains stationary, much easier to get your hands in a position they should not be vs. handling the tool w/stationary material.

Router scares me more than my table saw or chainsaw. The image of losing control and my router bouncing around with a spinning bit pops into my head every time I pick it up.

Really nice work so far though! Are you going to use the screw and glue method like dtsdig or straps? I couldn't find an easy way to do it with just straps.

Whenever I did my towers, I used titebond with staples and then used packing clear stretch wrap. This held it extremely well and didn't have to worry about any shifting (and that was with 56" of height vs 8.5")

@aaronlinkous You've mentioned that you used staples to hold down the curved layers in addition to the stretch wrap? How much holding power do the staples have in an application like this? Do you think they would hold down my curved layers adequately or do I need to stick with screws? I see there are 18 gauge narrow crown staplers available for around $30 so if that would work, I might do it to save the time (and my shoulders killing me) compared to using 90 screws.

They should be plenty. We had zero issues with mine but in reality it's probably more the shrinkwrap that is doing the holding. After about 5 or so wraps of that stuff, it has plenty of clamping power for the glue to grab hold.

Thanks! I am going to pick this stapler up tonight and give it a try. Besides, I love buying tools!

If the staples can hold the panel down while I work from front to back, then I can use ratchet straps just as backup if need be.

Awesome build so far. I sketched up a very similar design to that but still have yet to even start building, even though I bought all the components.

So long time, no update... Been traveling just about every other week since mid January and been sick. However, I have gotten these guys pretty much finished up. Learned a very valuable lesson: Always buy paperbacked veneer! I bought the same stuff (or so I thought) as I did for my other speakers. Same shelf at the same store. NOPE! This was just raw veneer without any backing and was brittle as all hell. Thankfully, most of the splits and cracks are on the backside edges just because of the way I laid it down, but still... quite annoying. The particle board you see in the back is there just to make sure I had something a bit more solid to attach the XO to. Kind of ran out of room with the port at the bottom and the curved sides.

Should go off to my buddies shop this week for stain (where I will try to find out what brand/colors he used last time are) and clear.

Now I just need to get off my butt and unhook my sub and get it sanded and buy more veener :/
