First time lightstand/B800 user... what is wrong here?

Got my light stands in. Ravelli ABSL background stands that I'm using for my light stands for now and trying to attach the B800 to it and although it tightens up the pin design allows it to wiggle. I'm certain this can't be the right pin setup to use.

what am I suppose to be using here. help! lol... thanks

Did you loosen the AB screw out fully so it drops completely onto the light stand shaft?

Loosen the screw till it slides all the way on there then screw it tight and it should be wiggle free.

Have you tried flipping the threaded stud around? One end is actually longer than the other and looks like you are trying to attach to the longer end in your photo. If that doesn't work, I'd suggest purchasing a female stud (pin) without the threads.

I have a dozen stands/brackets/monopo​ds/etc to screw these onto
for the most part, its tight, but there are a couple that have a little bit of wiggle... still feels safe and has no impact on what I'm trying to do...

A little wiggle is not really an issue unless you are working in hurricane force winds. The weight of the light and modifier holds them in place unless there is some force providing lift.

Yeah, the little wiggle is really not an issue once the set screw is tight, but some of those receptacles on the newer alien bees really are cruddy. I don't know if it's a bad batch or what, but a few of mine don't fit well at all with any of the stands I've used.

How are they different? How are they failing? Its a set screw in a round tube, it cant be that much different.

LOL Now you know how frustrated I was when the new lights showed up and they just don't fit as well as before.

I haven't taken the time to figure it out for sure, but I suspect that the tube tapers a little bit towards the top/inside. Basically, the round tube isn't really round.

Measuring on my monitor, the brass spigot is 15mm long to the upper wide area, while the threads add about 4mm to the length. Meanwhile the AB mount hole appears to be 15mm deep, so unless there is sufficient smaller hole for the threads, the spigot is sitting about 4mm out of the AB mount and prevented from seating fully by the length of the threads.

If you have no use whatsoever for the threads on the end of the 5/8" spigot, then simply use a hacksaw to remove the threaded portion. That will make it easier to mount a light to the spigot.

Not to put too fine a point on it, but I checked it with the back end of a drill bit, and the bit gets caught by a little ridge inside the hole (preventing the light front seating properly in every stand I've used). Just a little bit of deformation inside there, and I will just bore it out so that inside diameter is more uniform.

I took some pics of the old and new parts on the strobe. Old is on top, and it used a thicker metal liner. New is on the bottom, and the liner appears to be plastic. The "ridge" is just inside of where the liner ends.

All plastic? That saddens me.

So this is called a spigot?

This has threads because it's for a background stand. The cross bar fits over this then you use a washer and wingnut to lock it down. I do not want to cut the threads.

I need to order a spigot that will work out better. It wobbles pretty good. I don't want any stress

screw it i can get a piece of pipe and use it. be stronger than anything out there.

topic done.
