I've never seen Russian Birch in 5mm, It's always 1/4" / 6mm that I see. I've used tons of that stuff for boomerangs, and it's mostly OK. The funny thing is...
WOW! Thank you Dave. So much information. I think that I will go with the Russian Birch 1/4" plywood that I can get at Home Depot for $6.95 for a 24" X 48"...
Just make sure you get a piece that's nice & flat. Chances are that a piece already cut to that size and is still flat, will stay flat. Have Fun! Dave -- "Art"...
Thank you. I appreciate your taking the time to answer my questions. Art ... From: dlhughes001@... To: Boomerang_Talk@yahoogroups.com Sent: Friday, August...
I just went and checked (Im cutting a few booms today) and In my shop right now, I have 5 ply 6.1mm Russian and 6.5mm Russian. I measured with digital...

I have, what was sold to me as.. Russian 6mm 5ply birch plywood. I have heard from several boom enthusiasts who actually claim it's all 1/4", and not 6mm....
Art, The Home Depot stores near me carry a birch plywood, which appears to be 1 thick layer of cheap wood, with a thin vaneer of birch on the top and bottom....
Dear Boomerang Throwers, I'm looking for some information for those of you who are knowledgeable of solenoid technology. This is boomerang related although I...
I'm not sure what you're trying to do, but I have considered modifying a skeet shooting thing.. the little machine thing used to throw the clay pigeons into...

Sam, I'm not attempting to simulate a throw. Related to the parameters I described in my previous post I need a device that's independent of AC that's...
Thanks Dean. Many of my boomerangs are decorated with acrylic paints. I use black india ink along with the acrylic for outline and detail work. I use spray...
The force is equal to Mass*Gravity*height... I'm used to working in SI units, so (0.05+1.8)*9.81*3.05= about 55.5N (assuming my translations from pounds/feet...
Hey Morri! I believe you've asked me about this before. I suggested a solenoid from a car's starter. It's powered by DC volts and it also spins immediately...
Tim and John, Tim is 55.5N (newtons?) and the actuator arm I'm refering to is the arm of the solenoid with 4oz attached to the arm on a vertical plane. The ...
Hi Morri! Yeah, Newtons are the standard unit for force... I have no idea what the imperial units are. A lecturer was talking about slugs per feet squared the ...
Hello all, Aircraft Spruce..... yep, thats the place I use. You can get a piece of the 12 ply there for $35 I think thats a 24x48". that'll made a lot of...

I was playing with some of my birch plywood today and found something- The 6.5mm 5 ply came in a 4' by 8' sheet and has the "red" glue. The 6.1mm 5 ply came in...
Howdy! I was playing with some 5ply Birch today and cut and shaped some booms to try a couple of different coloring methods. I posted the result photos and...
'Battery Powered' is going to be the hard part. I assume you want it 'car battery powered'? Or are you talking about two-d-cells battery powered? Since you're...
The force needed to propel the boom up into the air will depend on more that the force applied by the actuator. And I wouldn't go the pneumatic route, because...
Why don't you make us a little sketch of the apparatus you envision, which will give us a better idea what you're trying to accomplish? DLHughes -- "M. Mohr"...
Hey Tim, I've had the same issue with some wood of mine but your question has me thinking out loud... What if you traced out a "tune form" on a piece of 3/4"...
So you use the india ink to outline. Interesting. Im guessing yuo already ahve the boom finished and sealed and then do the acrilic and then the india ink?...
Morri Did you ever consider the solenoids used in rc planes. Some of those planes can get fairly large, I have no idea as to weight, but the force on the ...
