JB weld

personally I wouldn't rely on PVC for a RC Kart...

Yes I know last years PVC Kart and I remember that it was cheated a bit ..
still awesome... but to add rigidity he cheated a bit

So I'd use steel tubeing for a project like this..
and if you don't want to or are unable to weld the tubes..
use connectors... there are nice railing connectors ou there.. they should take 1" tubing and with a few setscrews (and through bolts) they should provide enough strength for an unmanned vehicle of your desired size.
something like this
Also: it'll look cooler than PVC

No honestly.. as soon as you find someone willing and able to weld it up, you can remove the connectors and weld everything up just as it should be

Pvc does flex
Over 8 foot its really bendy

Ever got a 1 foot section and tried to bend it

Its pretty ridgid

And u don't want a totally ridgid frame anyhow

You need to get the thinest walling 1 inch tube you can and use these 'key clamp' brackets. There designed for express handrails but you only need an Allen key (6mm).

Where are they for sale at?

 

[davidbooth1991]

F.h brundle sell them and steel stockists do them b&m steel or fabricator workshops might let you have some. Just Google one inch key clamp for handrail.

They're really expensive fittings, for little more than decrative approach to them.

Just for fun i may even build a pvc r/c about 3 feet long with a weedwacker motor just to see how it works. 3/4 pvc pipe elbows tees and misc fittings and good to go.

Hmmmm, I always wanted a boat..... I could do an r/c pontoon boat with a weed eater shaft down into the water.....

Go for it and post a thread

Thinking the servks are going to be the most expensuve parts
I might have to give this a shot
Do some reasearch on prices when I get home

Got a spare 35cc wipper snipper motor and a whole pile of pvc pope abd fittings left over from my retic fit

I obviously can weld and have a welder so it wont be a true complete pvc chassis
