Chassis - Racking
By: robinhoodguy Date: December 16, 2025, 3:49 am

Has anyone ever made a chassis from this sort of racking? I was
wondering if it would work to make a weld free chassis?

The problem with these types of fabrications is that the
fasteners are at the points of highest load and subsequently are
very prone to wear and becoming loose. The stresses can be
lowered by adding triangular webs at the joints, fish-plates,
etc which also allows many more fasteners to be added. All
holes should ideally be close tolerance, but wear and becoming
loose will always be a problem.

thank you, yes that makes sense. I suppose when you reach the
point that it requires more work then steel section, (unless you
have lots of sopare racking hanging around) it isnt worth doing

I am experimenting with a (mainly) no weld aluminium chassis. Be
aware that it is an experiment but here is my process so far.
The chassis long members are a heavy duty ladder with
[font=times new roman]D [/font]section stiles. The cross members
are 40x40 mm aluminium box and held in place by 40 x 40 x 6mm.
aluminium angle. The main joints are then fish plated. All the
joints are first well prepared with the oxidation removed and
glued with MMA structural adhesive on all parts then riveted.
Properly applied in good conditions MMA will have the shear
strength of 2 number 8.8 grade M8 bolts on a 80mm x 40mm surface
area (my typical area of each joint). It is more resistant to
shock than most commonly available epoxy resins.
From the construction I have completed so far this seems to
providing strong joints. Time will tell.
This fellow has a video of bonding aluminium with various
adhesives, although his pronunciation of Methyl MethAcrylate
might be a bit suspect...

As I mentioned at the start, experimental!

Having used this sort of racking to make channels on my trailer
it's surprising how flimsy it is. It would be alot of hassle to
make it work id have thought.
If your reluctant to weld because you can't, I couldn't before I
built a Cyclekart, and just practiced a bit with a cheap gasless
mig welder. Ive now made 2 Cyclekarts and a trailer and non of
them have fallen apart yet 😁

Have a look at Peter Lloyd Austin 7 build journal :). Its a
Bolt together Aluminium Chassis. Not exactly racking but
definitely an over the counter component sectional system.
