im gonna try build a tube chassis, wanna make it outta stainless, what i was wondering is if 1/8" rod is enough or should i use 3/16" rod?

PEDEcrawlerguy · 03-31-2009, 04:01 PM

what scale are you wanting to make it?... 1/8" would be good if you want to run TLT, or Axial axles... if you want to run axles bigger than those, you might want to consider bigger material.

Yup, what he said

Might look a little small depending on the over all size of the rig, but it should be strong enough.

if this is your first attempt at a tuber i would use 3/16" brake line from you local auto parts store, its cheap, about $6 (CDN) for 5 feet of it...

unless you have a fair bit of previous fabrication experiance you will probably end up wasteing a bit of material so get some practice with the cheap stuff first. just my $0.02

side note: i live on an "island" (not a small one by any mean) so things like steel tend to be more expensive then on the main land... so maybe price of material wont effect you enough to care about

in which case just for looks i would use 3/16 for the main body lines and 1/8th for things like roof hoops and "X" braces

Solid SS rod, is a little on the heavy side, not anything wrong with that. 3/16" brake line is easy to bend and holds up pretty well. For 1:10 scale,3/16 is about the right size to duplicate 2" tubing used on full sized tubers.

yeah ill be using tlt axles, and i work with metal, never tig welded before but im a fast learner, and a 12 ft lenght of 3/16 is only about 8 bucks and 1/8 is 6 bucks i think ill do the main part outta the 3/16 and the braces and whtnot with the 1/8 thanks for the tips

ultimate_monkey · 03-31-2009, 10:48 PM

haha wow that is quite a price differance, 12' SS here would be more like 20-25... so ya id just go for the SS at that price..

TIG welding is easy! way back when i was getting my welding tickets, it took me about 3 minuters of trial and error befor i was gettin good welds so i dont think you should have any problem picking it up, and its not like you have to lay down nice beads either just meling two rods togeather with a little bit of filler added

yeah i never priced meatl before, when i called the supply store, i asked for the 3/16 rod, he told me 725, and said $725.00, and he laughed and said no, 7.25, and i dont think i can get brakeline for that cheap
