Thanks Sporty & Stan.

The small stuff, like 1/8" dia, is very brittle. It breaks easily when held in a vice and hit with a hammer. The break is not well controlled and, if not restrained, the pieces broken off will fly across the room. I slipped a length of latex tubing over the free end to keep mine from flying off!pwrd by tungsten wrote:You should be able to get tungsten welding rod in the right size.

Sporty, I'll blank out that post if you wish. Let 'em figure it out for themselves???
Just a few minutes spent using http://www.stanpope.net/cmcomput.htm, building up piece by piece. The 0.24 and 1.96 oz numbers based on weighings of "similar parts" here. My grandson and his daddy weighed them carefully for me! But recognizing that "similar" is not "exact", I identified the numbers as "approximate!"sporty wrote:No, Stan, thanks for doing it.pwrd by tungsten wrote:... And thanks Stan for the breakdown.

Thought I saw a trim weight under the rear axle area???sporty wrote:I usually have a tad bit of weight on the top for fine tuning and adjustment. Those were old pictures though.
Thank you.Nate wrote:Thanks for the advice guys!
So Sporty, what you're saying is that you've the COM being lower is way more important than it being concentrated? That makes sense.
I think I'll attempt that weighting style this time around, with a couple modifications to the body. I ordered about ten yards of 3/8" carbon fiber tube for another project last year, and still have some left. I should be able to get a tad less mass in the front end by using that as a mid section without sacrificing stiffness.
Out of curiosity, what size cubes are you guys using, Sporty & pwrdbytungsten?
Stan, that's a sweet little web tool!
Cool!Nate wrote: I've used carbon fiber before and have a method developed with little to no construction failure risk.
