What is the easiest way to build a spindle jig. I have a few ideas but I thought I'd ask the guys with spindle jig experience . Pics of your jigs would be cool.

Spindle jig?

Yup a jig - a plate, box, or open frame for holding work and for guiding a machine tool to the work, used especially for locating and spacing drilled holes; fixture.
We use 'em to line up fins on model rockets perfectly. Like a guide.
Sounds like we found your next tutorial!

I agree a jig sticky would be useful . I'll take lots of pics and maybe video if I can when Ido mine. I discovered my spindles are not the same. Its a leading arm set up. The spindle arms are at different angles. I might switch to a trailing arm set up but to do that Ihave to re do the entire steering set up. Any easy to fab jigs would help.

I know what a jig is, I've made many in my time but, personally, I don't have one for making spindles.
A jig is usually used in high number production scenarios, so that 1000 items are all identical but, given that most of us would only ever make one or two pairs of spindles in our lifetime, the need for a jig seems redundant

Wood is easy to work with. You could make something up using dimensional lumber, or maybe even MDF. I suppose the trick is to find a way to prevent the material from scorching during tack-welding... Hmm- don't want to wet it down (especially MDF). I wonder if there's a flame-resistant coating that can be applied to it.
EDIT- Fab- it's not redundant- if you have to make more than one (like... 2) identical and perfect, a jig is a good plan. Heck- frmes are very often done on purpose-build jigs even when only one is being made!

The difference between a mass production jig and a custom jig is the number of times it is used to make a perfect piece. Its not necessary but its a tool that makes the job easier .

but, all I'm saying is how many of us are that pedantic? Then again, most of you simply buy spindles & modify them to fit/work if necessary.My point remains, I'd be surprised if anyone here has made one...

I've doodled out an idea using 2x4s , I'm not worried about it catching fire since I'll only use the jig to tack the arm in place. I'll dunk it in water to retard fire. I'll take lots of pics for the pedantic folk.

Cool, that'll do it (on all points)

Spindle jigs are very important, maybe not for a yard cart. but i bet almost anyone who has made a buggy or full suspension cart has used a jig for spindles, even control arms most likely. Your cart is gonna handle like a turd if your steering geometry isn't designed properly. and if you have 8* of kpi and 5* of camber on one side, and then 4* of kpi and 0* camber on the other side, you think thats gonna help?

That's a House-Of-Horrors thing!I would not call any of this pedantic. The Kaptain makes a valid point, exaggerated for illustration. How many times have we seen somebody come on and say "My kart steers like a turd!". Around here, we advise good steering geometry fundamentals because we know what tends to work, and what doesn't. And let's face it- getting something this small and light to steer with a live axle is an uphill battle to begin with. So- does it not make perfect sense to try to eliminate one more potential problem from the equation?

Point taken &,
completely.Don't get me wrong, I'm not trying to trivialise the concept, I believe it's very important (how often do you see me ranting about steering geometry?) but, toystory actually makes my point for me; a large percentage of members don't put enough emphasis on correct steering setup.

I'm had something like that going on with my old kart. Except that it was close to 20 and 15 for the camber and about 0* and 10* forward for the caster, no ackerman. And the scary part is that the kart was built with no caster or camber. The front end was adjusted on the fly by stumps, rocks and unexpected air along with the odd intentional jump as well.
