I have decided to use one of the bamboo boxes from Wal Mart to house my 832A stereo amp. How do you cut neat holes in bamboo without splintering it? My Forschner bits have saw teeth around the edges and that`s not good. Thanks, Robert P.

Hi Robert, any chance you could post some more details on the bamboo boxes from WalMart (photos, size, cost)? They seem like something us DIYers may be interested in.

Sorry, I have never worked with bamboo. What if you used a circle template and a sharp know to score the wood first?

Don't use a hole saw or spade bit; you'll splinter the hell out if it. Your best bet is probably drilling a small hole, then using a coping saw or scroll saw to cut out the actual hole.

Hello Gio, These bamboo boxes are made from 1/4 inch thick flattened and cured bamboo. They are 6X12X2&1/2 inches and are finished nicely. Thanks, Robert P.

Another 832-phreek!!!! :up:

I know there's a speakproject in German Klang&Ton where a bamboo bowl from IKEA is used. I have to check if I have that issue and if there's anything written how the hole was made.


They are using a router to make the big holes for the 4# fullrange speaker.

I found how to cut the bamboo. I used a Roto Zip spiral cut tool that cuts with the side of its drill bit looking cutter. It is like a larger version of a Dremel tool. It cut my big tube socket holes with no splinters at all. I also found that the deck of the bamboo box is only about 3/16 inch thick (3.6mm) so I will mount the volume control between the driver tubes as close to the front side as I can. So far I have all the passive parts and the iron on the way. I just recieved the Edcor iron for the Pete Millett Engineers Amp so I guess I`ll work on it while waiting for the rest of the parts for this 832 project. Tubes are cool!! Robert P.

Thanks for sharing that info Robert. Hopefully those bamboo boxes are also available in the Canadian Wal-Marts.
Cheers

I've used the bamboo boxes several times for headphone amps. My sweetie picked them up at Kohl's. I've never seen any this big, though. Nice idea.

Cheers, Greg

Hi All,

I purchased the same box from World Market to house my PS for under $5.

I'm not sure if it's real bamboo or just finished to look like it. It drilled and cut like wood.
