Butt joints in chassis rails

I had someone distraught over me having but joints in the side chassis rails of my build. Sure as anything that the car could break in half at a serious bump or drop. I have been building my chassis based on the bood desing but with changes. I have but joints in the places the bood does and one extra one where I dropped the side down at an angle to where your elbow sits.
Has anyone ever heard of this happening - I would be concerned more if it was a standard 3000-4000 lb car. But Safety is an issue for me so I like to look into any concerns.
Here is a shot of the areas - just tacked together in the pick.

Prat then obviously...as cut n shut welded tubes are far stronger than bent round or square tubes. You just have to be canny when dressing the faces you want panels to fit against and leave those that don't.

Prat = bulls#$t? A Canadian here so not 100% on the term. I assume the design is ok or there would be a 1000 locusts sitting in the scrappers in 2 pieces.

Prat = fool, idiot etc.

I can't see anything wrong with your chassis design. As long as the welds are up to scratch then you should have no problems.

Thanks for the replies- I was pretty sure that it was good. I also believe in not having single points of failure if at all possible so I have every intension of putting extra braces,gussets ect to prevent any chance of an accident.

Thanks

if you

if you are not sure you can also cut an triangle from 2mm sheet size you prefer
(bigger= stonger but heavier)

and weld it in the corner it wil make the union as strong as it can be...

Lighter prettier way to gusset a corner is to cut a piece of the same size box section at 45degrees both ways ...making a triangle shaped channel(if that makes sense)......weld that in but make sure you don't weld it all in one hit as the heat will bend the chassis like a nana

piece of sheet is stiffer

but maybe also it weigts more..

will do an calc one moment..




ok an 100mm bij 100mm cut in half (45degrees) weights in at 0,079 kg
2mm sheet (mild steel)

an boxes piece with 1,5mm body an lengt of 150mm (both sides angled at 45degrees) weights in at : 0,139 kg

if we use 3mm sheet if weigts 0,118 kg
same seize.. as before

sow make conslusion
