Rear i am using factory point so far but looking to add another on there possibly on the rear bar of drews.

There is no way I would use one of those two holes to snatch from.

Thats what i was thinking. What are the two holes on either side on the main uprights for? I have a hook here (fits perfectly but dont use it as one of the chassis mounts is broken on the bar.,

The point that is being missed here is not how tough is a tow ball, the point is what is the best practice ?
IF the tow ball breaks you have a 1KG lump of steel wrenched free with a very substantial force.
You want try to minimise the weight of the projectile if (when) something does go wrong.

If an entire tow bar gave way, hopefully it's very poor aerodynamics and it's own weight will keep it pretty low and rather hopefully entangle itself with the ground, bullbar or bonnet before it reaches the driver of the stuck truck (this is unlikely with a tow ball in a slingshot)..

Also I would not use the eyes on a bullbar even if reinforced, as I have seen them tear open on a few occasions, the recoil from the snatch strap, with the d shackle attached put a large gouge in one of those triangle anti inversion ARB spring shackles sheared the head of the grade 8 bolt on the spring shackle and proceeded to rip a good 8 inch hole in a fuel tank. The actual damage the strap itself did was not that bad (If only the strap had hit a person, they would be pretty sore but OK, if the shackle had hit em as well ... you would have to pick up bits of human to hopefully be sewn back together)

Ahhh physics.

44 Years ago was the last lesson I had on physics ... didn't mean much to me then & it still gets my brain in a tangle.

Newtons.

Only Newtons' I know of are Sir Isacc Newton & Bert Newton. The former could possibly solve this puzzle whereas the latter would be as usefull as a bridle on a vaulting horse.

You lot are much more knowledgeable & experienced than me - by the sound of it - what little I do know tells me NOT to use the tow ball for ANY type of recovery. I guess that's simply common sense.

Keep at it you blokes - I'll check back in a couple of days.

who uses an 'air brake' when snatching?

It has a 10,000lb rating and is held by 4x12mm grade 8 bolts.
These hooks were designed to replace the D hook for Nissans but they run 4x10mm bolts. I had to reem the holes out a bit to take the Paj 12mm bolts. As I don't tow or have a HD tow bar it was a good option for me.
Most of the guys I wheel with have winches anyway so extreme snatching is hardly ever done. I only carry an 8,000lb snatch strap so that will break well before the hook or bolts.

These are a good idea BUT, if the original weld nuts are used they will be soft and may fail in the threads. Use new nuts behind the plate.
