just decided on my first build, the Voyageur, as it looks more straight forwards as a first one.
now back to the title, it says in the plans 1.5 inch steel tube/box, at 16 gauge, well I have spotted some tubing in the same sizes but in alloy. would/should it be either thicker gauge or larger diameter for alloy?
or should I just stick with the steel?

I built the Voyageur from 16g steel , nice easy build and rides well ( once mastered ) , easy to weld up as there is not much of it ,
problem with going larger diameter and ally would be the need to build your own head tube and then you have a little opportunity with the swing arm mount , personally I say go with 40mm 16g steel .

After you have built it its a easy modification to convert to a streetfox style tadpole ( leaner meaner thread ) or the feb 2014 newletter .

....wouldn't recommend aly for one of Brad's plans unless you really know what you're doing. One thing to consider is an aly frame must me baked in a special oven after welding to gain it's strength back, around half is lost during welding. Aly and steel - like comparing chalk and cheese :)

The type of material you use is totally dependent on the type of welder you are using. For a stick or fluxcore mig stay with steel as you can weld it. If your using Tig then Alloy is fine. But I cannot guess on thickness other than comparing strength of it. It also depend on which mix of alloy your using. Some have more rigidity than others. For simplicity stick with mild steel unless your familiar with how to weld it.
For example FrankCrank in Thailand is using 304 Stainless with his new Streetfox build. However he is Tig welding it. I'm not sure if he is using thinner than 16 gauge or not. I don't recall.

I'll stick with steel, as I have access to both mig and stick without calling in any "special" favours of my mate who tigs for a living

....just to clarify, my mk2 trike (not Streetfox - own design) is indeed being made from 304 stainless - easy to obtain where I live. In fact, could probably reach a dozen suppliers just an hours drive from my house, no need for any special deliveries etc.

The main chassis is 1"x2" rectangular with around 0.8/0.85mm wall thickness, depending where you measure. The stays are 20mm diameter tube, again around 0.8mm wall. I think in old money that's about 22 gauge.

I'm TIG welding this of course, and still managing to blow a hole now and then. Easy enough to fill, but heat spot can cause warping - definitely gotta try and keep focused on the job. Nothing wrong with mild steel - would recommend it for a first build, can always upgrade the material on a subsequent build if it's a keeper.

Anyways - have fun with your build(s) and keep us posted............

Steel is an alloy of iron with carbon and other elements...
so which alloy are you talking about as an alternative to steel?

I think it is safe to say that he is strongly recommending that you stick (weld?) with steel for your first build!!!!
I tend to agree that it would be safer to stick to steel unless yoreally know what you are doing as a welder and as a builder!
Main thing is to have fun and get a good bike to enjoy.

Hi Vic,
In my eagerness to respond to the first question, and to provide a little humour, I slipped with my manners! Sorry.
I should have said """Welcome to the group!!!!""""
Feel better now.

here's one I built earlier using 1.5" steel square tubing it took three time as long to convert it into my e-trike than it did to build it .( or 1/2 the time for my gravel rash to heal ) I never even got around to painting it .

I don't like gravel rash had enough of I from motor bike "offs" are they quite hard to master?

The only thing I had a problem with was the transition between stationary and moving , on the straight and downhill there was not a problem , uphill starts take a bit of getting used to I could do it all if I held onto something and pushed myself away , BUT hey ho I am not a spring chicken any more , I personally found the long wheelbase ( I think mine was longer than it could have been might have been another contributing factor ) but 3 weeks after I built it .... it looked like this :surprised:

But that is the nice thing about these plans ....

Problem is, this hobby is ADDICTIVE ( 4 trikes +1 short lived bike in a year )
