STAINLESS METAL vs DOM METAL

CRACKERSTYLE

Well-known member
Building new rigging soon and wanted some opinions on which metal to use. I have a 4 cylinder Lycoming and just plan on running me my wife ( 2 dogs occasionaly). Might do a little hog hunting out of it and like running the hill. What are the pros and cons of each metal. I want it light but i dont want it to break. I hate grounded off powder coat and welding it.
Stainless seems to have its benefits
NO powder coat
re-weld anytime
wont rust out (from the inside)
BUT is it heavy. If i build the identical rig out of stainless or dom whats the weight difference. I hear they us .049 for DOM and .060 for stainless
Conduit is cheap but you get what you pay for
square tubing is heavy, I AINT HAULING THE KITCHEN SINK
little help ....... anybody....dakota........predetor0470
 
I know that on DOM it is .065 thick that is what every body uses as for conduit it is only .050 thick and square tubing is .065 witch is 1/16Th thick as for stainless I will have to mic it tomorrow and see how thick it is for got to do that one.

But a square is stronger than round and (so far) I have not had any square tubing crack.
 
c chardt, I'm waiting for a call back from Praxair on different gases for stainless as it seems that there are several mixes to choose from. Here is a link for various gases dealing with stainless welding. I believe the A1025 is fairly new as the salesperson stated they had recently heard about it at a seminar.

It seems that the Helistar A1025 and Helistar SS would be good choices.

Any luck contacting Continental for stainless stock? I plan on going with 316 "marine grade" when I do my rebuild due to resistance to corrosion.

cchardt , I thought that square tubing was as light as DOM. I know that you build rigging out of both. Is there much difference in weight?
 
Cracker style my new boat has stainless rigging for them exact reason. I tend to run my stuff hard and hit trees occasionally roll on the side along with just putting alot of time on my boats. Forget about the extra 30 pounds and just make more horsepower!
 
DOM is light and strong, its a god choice for riggin a light 4 cyl.- 2 or my buddies built their riggin w/ it one has a ultralight diamondback w/ a 160 and one has a willcox (i think) w/ a 180 and both boats will get down n dirty n go about anywhere my 540 will.. i think DOM is good for light 4 cylinders in my own opinion. :D
 
Not much of a difference on weight if you are comparing same wall thickness and size. Your talking a difference of .07 pounds per square foot on .060". Figuring Weights with different wall thicknesses are easy as long as you have figured out the product with one wall thickness and have weights for the others. 8)
 
I hear this from every body square tubing is heavy (WELL THAT'S WHAT MY FRIEND SAYS) so far every one that has went with my square tubing has had not the first complaint and its not heavy if it was I would not use it It's not solid.
I have weighted a FULL stick of 1/2 in square tubing and a 24 ft stick is 8 lbs a stick 24 ft long of 3/4 is 12 lbs and 1"not sure will weight it.

I have built a couple of boats for a buddy of mine one being square tubing and one out of Dom well the square tubing boat is still together the Dom boat has had alot of brakes and bends so he just built a new boat and went back to square tubing.

I have built cages out of square tubing the weight 52 lbs and the air boat shop said there's start at 60 lbs and go up to 90 lbs

On the average my whole seat package motor stand and cage are between 150 and 180 lbs depends on how big and how high the metal works are .

One question (How many of you have weighted your metal works ) I try to weight all of mine and document it with a photo so I know what they all weight I have took Conduit cages off that weighted 150lbs and replaced them with a 52 lb square tubing cage
done a few others that took 3 people to take them off and replaced them with square tubing and put them on and off by my self

If it was heavy I would have to hire some one to work with me to help carry every piece .

I DON'T USE SOLID SQUARE TUBING AND IT'S NOT HEAVY I HAVE HEARD THAT NO ONE LIKES CHANGE!

I LIKE TO BE DIFFERENT that way no one can say that I copied them or it looks like such and such. This is my own style and no one Else's and not a copy
 
The major problem with DOM it rusts twice as fast as everything else. I see DOM boats all the time less then one year old with rust stains all over them. The only reason to run DOM is weight and it welds much better then conduit! I will never own another DOM boat! Unless I plan on building a new boat within three years! The major benefits of conduit is it's cheap and it's galvanized, done right it will last a decade! I don't care about weight so I'm going stainless because I rip up my wire alot running thru trees where we ride there is a ton of brush and woods busting!
 
I biult my riggin out of square tube stainless. Seat stand is 3/4" and 1/2" with the mtor stand in 1" brush finish. the cage is polished round stainless. i did not want to repaint every year to keep it lookin good. i am running a O435 so we will see how she goes. If she doesnt go good enough i will take water thunders advise MORE HORSE POWER!!!!!!
 
Well I just mic a 5/8 diameter piece of stainless and it was .075 thick and just got a quote from the metal distributor and 1" 304 stainless pipe has a wall thickness of .133 and for 3/4 round stainless 304 wall thickness of .113 so i guess that it would be alot heaver than any of the others.
 
Hey Dakota
Have you taken the different metals in same length and weighed them
10' conduit 1/2" ?lbs
10' stainless 1/2" ?lbs
10' square 1/2" ?lbs
10' DOM 1/2" ?lbs
you get the idea
 
Dom & Square tubing being noncoated will rust from the inside no matter
how good you prep and coat the out side. I've run a conduit rigging for
about ten years untill it rusted out. You can go stronger, you can go
lighter, or you can go more durable, but for the money good old EMT
is hard to beat. and if you need to make a repair at 8 PM on friday night
just run up to HomeDepot and your in business.
 
c chardt

I remember you mentioning getting a new bender. Just wondering what you got and how well it works. I can get a hydraulic bottle jack one up here pretty inexpensive, just not sure how well they work? :? Thanks!
 
Man,

Nothing like being stuck in the dark ages huh?

I got CC workin on my new titanium rigging for the new airboat demolition derby :D

I think cause the chicks dig it is really why he builds em' square :wink:

Basketcase
 
Thoose hydraulic jack type benders work pretty good on
heavy walled pipe like sch. 40 blk. or galv. but did not have
much luck bending thin wall stuff, it always seemed to kink
maybe I was doing it wrong.
