Hi Gang,
(First an apology/explanation; I have not posted many of my projects because I’m lazy when it comes to documenting my work. Over the next few months I’ll try to get several of my projects presented here. Another excuse I have is that my picture taking skills are very poor, but I enjoy woodworking, so who cares?)
One of the Docs I work for asked me if I could make some speakers for him based on plans he downloaded from a DIY audio website. The model called Sashiko looked simple, The majority of materials was 3/4 Cherry ply edged with with Cherry. I made the bases from book matched Alder. Both front and back cradles are bookmatched and the stretchers (unseen, but necessary for stability ) are also made from Alder. The most difficult part of the project was creating the phase rings. I glued up segments of Alder , bandsawed the circle and used a router to smooth the circumference – including the cove – and finished sanding them on my lathe. The internal baffles were secured with floating tenons and glued. I determined that the tenons were the best way to secure the baffles were I wanted them while the glue sets up.
The Sashiko plans are no longer posted on the Frugal Horn site but if you look at the Kirishime plans you can see the number of pieces needed inside the carcasses. (http://frugal-horn.com/spawn.html) All pieces except for the Alder were finished with Bartley’s wipe on poly gel.

I made these speakers in 2011 and they survived a move from Baltimore to New York.

My friend purchased the drivers, all cabling and connectors, and the brass feet I know very little about drivers but was impressed to discover they were made from banana skin pulp.

Well, thanks for looking, maybe some day my picture taking will improve

Very nice work and a great result Marc. I wouldn’t worry too much about the photography. Most of us just use our mobil phones to take photos and do the best we can.

Hi Jen,
Thanks for the compliment. I’m a persistent fan of the music (asterisk) of Frank Zappa so I got to hear Hot Rats (the cd version, too bad it was not the original LP mix) played through these and it sounded better than I can remember on my old stereo system. My friend enjoys a mix of tunes and he played some jazz pieces that had some very nice bass lines. The low ranges seemed to come out slightly delayed as compared the higher frequencies. I was really impressed. Too bad I did not go over his house very often from that time . .. .. Marc
(asterisk) I thoroughly enjoy Frank’s music, some of the lyrics just get in the way.
(asterisk) instead of the real asterisk, because a real one caused all of the fonts between them to become bold)
