New uFonken Build Started

[timske]

Just started building them. Building with Birdseye Maple and Purple Heart. A lot of mill work to clean them down to .5 inches from large rough cut 3/4'' boards. I am going to leave the Base of the enclosure at 3/4 inch to help add a little weight to it.

Hope to get the rest done here in the next week or so.

Wow, bold wood choices. I'm going to keep my eye on this!

These will be lookers! What goes in there, FF85WK I presume?

Tim,

The freely available plans for the uFonken are for the FF85k, there are 2 minor changes for the FF85wk.

If you haven't already caught those, vent height changes to 12mm and the vent spacer should be 17mm wide.

Oooooo Thanks for the catch Dave, I am using the WK version and I didn't see that or count it in, I will make a few new cuts ^_^ (I know I bought spare wood for a reason).

The boxes are already a little modified I have the front baffle only going down to the vent plate (so I can alternate the wood colors) so what's a little more modification

As a side note once these are done I am planning a second set for my home office, these are for work. The second set will be out of African Teak with a walnut base. The teak is not a dense wood, but I love the colors

Dense is not an asset in itself. Stiffness is what is important, and sometimes high density comes along (like in stranded bamboo ply)

I finally got around to working on these a bit more (new home, new kid, new job = no time)

Finally started gluing them up only to find I had a lot of movement in the wood after letting them sit for so long. I hope some good glue and extra clamping can get all the warps out

Nice work, promising so far!

Just one little thing if you allow me: I see there is no chamfer on the inside of the driver hole. Are you planning on making one? This can still be done with an inverted chamber bit. It's really worth it, especially with such a tiny driver-to-lumber-thickness ratio.

Those look like they are going to be real pretty

So finally got them basically done, ill play with the fill a little bit maybe but for now I am going to let them break in. The base warped the tiniest bit and left an ever so small crack so we ended up placing an inlay to fill it in.

All together happy with the sound, now I need to figure out a good mini sub to fill in the low end just a tiny bit. Maybe a little tangband 3'' parabolic sub ??

Pictures to follow just need to clean them up a little bit.

Nice. You might try a little tilt-back.

So after a bit of break in they seem to have filled in a little bit. I added a little more fluff to the inside as I had it a bit light to start. overall really happy with these little guys ^_^

I may still add a small sub to fill in the low end, I may see if I can find a viable way to make something similar to this with 3'' sub drivers that can still hit 50hz.... that is small enough to sit on my desktop between the uFonkens. I know, not optimal.... but hey I can have a little fun

The Decware WO32 - High Performance HORN Subwoofer

I remember Steve's WO32 design from over a decade ago - probably moves a lot of air, sho 'nuff, but ain't compact - and "scaling" a horn based design doesn't always work

Timske: The colour contrast between the different sorts of wood are just beautiful. Wants..
