Hollow Handlebars vs solid handlebars

[DoGoodDrugs]

WaterHawk, why do you come on here acting like you know anything about engineering or strength and materials. As an engineer, anything you "designed" or even thought about would be completely suspect. At first I thought, well maybe since I'm an engineer not everyone knows the same stuff I know. But it seems like everyone else gets it but you.

It seems no one mentioned that the most likely failure force would a moment force on the bars. Little shear, no tensile, no torsion.

yea, sneaker wave.

When dealing with the same material (like we are, extruded 6061), the bar is going to be stronger than the tube just for the simple fact that there is more material there. Both are made the same way, by extruding hot material. Now if we were talking 6061 extruded bar VS stronger alloy tube (2024), we'd have a different scenario. The 2024 is going to be stronger pound for pound, but when comparing 2024 tube to 6061 rod, we are not talking pound for pound, we are talking inch for inch strength.

As an example of same material in solid and hollow form:

In automotive applications, you can gun drill your axles for a weight savings. Racers will do this because you can (for example) remove 50% (or more) of the material and only suffer a 20% (or less) loss in strength. If you could gun drill your axles, loose weight and gain strength, they'd just be made that way.

Now, you take some very tight tolerance seamless alloy tube, and you can engineer a tubular axle that is stronger and lighter than a solid or gun drilled axle. This is becoming popular in the 4x4 community when you start talking about 1.5" diameter axles that weigh a $hit-ton.

Now if you compare bending a tube and a bar, you need to consider that if the two are made from the SAME amount of material the tube will be more rigid.

Solid handlebars would be a waste of material, to me. I'd prefer to use a stainless tube, if I were bending aluminum tube bars.

thanks kurt. this is what I trying to explain.

Sure wish Charlie was on to read that right now. Loaded gun.

yeah, charlie is a genius of a "loaded gun" for sure. for some reason he thinks when you switch over to premix from oil injection, you should leave the oil injection pump hooked up pumping oil to the engine while running premix, and jets sized for fuel only. wow.

Not going to get into this. But, Travis, Charlie was only talking about doing that just for a few seconds until all the lines were primed with the new premix. Then you disconnect. He was not talking about leaving the injection system on there.

yes, I'm aware of that. the thing is, it can still put way too much oil vs. fuel through the engine while you're waiting for the lines to be primed. a waste of time, when you can just scrap the oil injection system completely, and flush the lines and the carb with premix, and get it over with. not to mention the situation about the jets.:cool2:

You do realize you can do it both ways............ You dont have to argue every point. If someone disagrees with you, that is their choice. This crap is getting old. Right now it the score is Travis 5, Charlie 8. First one to 10 wins an all expense paid trip to Neverland. Thats right, you can go visit Michael Jackson.

 

[the WaTeRhAwK]

yes, you can do it both ways, if you want to put too much oil though your engine, not change the jets, get a lean fuel condition and burn up your motor with too much oil. you're right harrison.

aside from that point, and "keeping score"..lol I was more concerned with the dude not trashing his setup than I was arguing with charlie. arguing with charlie is not my concern at all.

 

[the WaTeRhAwK]

harrison, it's cool how you are able to post replies in "locked" threads...LOL

I rest my case. You still did not read or listen. Have a good day.

No, it was obvious your main concern was to argue. You made it very confusing and difficult for the OP in that thread to understand what you were talking about. Probably same thing that is going on in this thread. If you do know what you are talking about (doubtful) you do not convey your message very well at all. You remind me of when I was 5 and I thought I knew everything, but couldn't put all the pieces together.

Why do I keep feeding the troll? You are good my friend... Hogwash

first off, I am NOT a troll, secondly, you obviously like to argue.


this is what people run into when someone is trying to make a technical point to avoid someone destroying their equipment. it happens all too often, and it's gotten very very old.

Harrison, I would like you to point out where I did not "read" or "listen" to you.

you are correct, I do NOT "have" to "argue" every point, and if someone disagrees, you are correct, that IS their "choice". however, if I see someone taking inexperienced, dumb, and stupid advice on how to "tweak" their motor, etc.. I'm not going to just sit idly by and watch them destroy their stuff just because someone "disagrees"...LOL

sorry.

Argue this point.
