Does $3.65 sound like a good price to pay for 1.75 x .120 dom?

price sounds good dont know where you are getting it but tube service in norwalk has about the best price and will deliver it to youre house for free.. smallest order they will do for anything is 250 dollars, try and get some otheres to go in and get some also the price wiolll drop more
 
I paid $3.02 for 132 ft (6 pcs. 22 ft length) of 2" X .125 wall DOM at TOTTON TUBE in Azuza. The difference in 1 3/4 to 2" dia tube denting is so small you wont be able to even tell. Has anyone ever actually done a dent comparason.....NO. I bought 2" because I wanted to build my rig to some kind of spec. SCORE rules say over 4000 Lbs requires 2" tube. Even though My truck IS NOT a desert truck is does not mean I wont have a high speed crash on the freeway. So thats why I went with 2" tube. Its heavier but not by much in the end. the bigger tube looks tough too.

It bugs me when people say this about 2" just because they herd it from someone else without actually knowing the facts. Sure, common sence tells you bigger tube would dent easier, But how much is the difference in force required to dent 1 3/4 compared to 2"?. If you go by that theory the why not use 1 1/2 tube or 1 1/4 tube.

Hell use 1 in for that matter it wont dent nearly as easy as 1 3/4. Give it a rest unless you have done a dent test with factual results. I think SCORE has done their homework, their safety record in desert racing speaks for itself, hence the reason Im using some means of rules to build my cage by.

Ofcourse cage design is EVERYTHING when building a cage. If you build a cage out of DOM and its designed crapy, it could fail far easier then a cage designed and built from HREW tube which is weaker tube. My personal choice was to use atleast some sort of rules to build by and Im happy with that decision.

Assuming that the difference in denting is only based on leverage the then 2" would be 12.5%.

Its been done thousands if not millions of times. If you want to compare yourself you can always put different pieces of tubing into a press and see how much load it takes to crush them (you can use some small point load to mimic the tube hitting a sharp rock).

Safety in a crash is a good reason to use bigger tube.

I never said I heard this from anyone, I'm giving you the facts.

If you go by that theory the why not use 1 1/2 tube or 1 1/4 tube.

Most buggies use smaller diameter tubing. My chassis made up of 1 5/8" .120" wall DOM and 1.5" .090" HREW. I plan on flopping it and having the tubing remain usable. 1 5/8" tubing is 33% harder to dent than 2".

I think SCORE has done their homework, their safety record in desert racing speaks for itself, hence the reason Im using some means of rules to build my cage by.

Of course SCORE has done their homework. They plan on the vehicle being crashed at high speeds (more than 100 mph), not everyone building a cage plans for or needs that.

Ofcourse cage design is EVERYTHING when building a cage. If you build a cage out of DOM and its designed crapy, it could fair far easier then a cage designed and built from HREW tube which is weaker tube.

I agree 100%

Just out of curiosity Im going to pinch a piece of 1 3/4 HREW and a piece of 2" HREW and measure the difference in deformation and calculate the difference.

Im sure it actually has been done, That WAS an incorrect statement on my part. I just feel you build a cage for overall structural safety not to be dent resistant. 2" may dent easier but is stronger because its bigger diameter, hence has more structural integrity.


Safety in a crash is a good reason to use bigger tube.


Agreed

Where did you get the facts?

A buggie is fine with 1 5/8, their light. 33% harder to dent but how much easier to bend and possibly fail before 2" will?

I agree 100%


"Not everybody building a cage plans for or needs that" True, but I plan on wheeling the poop out of my rig and more then likely I will see a roll at some point. Hopefully not but I prefer to prepare for the unexpected worst case scinario. even though thats never the plan to go down THAT road.

You have a few different openion and good valid replies. Its good to hear your views.
 
quick hijack.

If i build a tube winch bumper, on my truck (which is a daily driver) what size tube would i want. and what wall thickness.

thanks
