Default Maybe these?

I haven't tried these but I have thought about buying them and using them. Maybe someone can provide feedback. Just be careful, I've heard others that mess up and the jack goes through the wing.

Cut a piece of all-thread or an old bolt and run it into the tiedown hole. Round off the end sticking out so it fits in the top of a HF hydraulic jack (several threads on here about jacking the airplane). Unlikely to cause issues as long as the jack is stable.

I've been using hardware grade 3/8 bolts with a nut tightened up to the head for about 20 years without issue. I tighten the bolt / nut combination into the tie down leaving no thread exposed. This transfers the weight through the bolt head / nut directly to the wing. The jack rams are countersunk.

This method was used for about 18 years on our Mooney for tire changes, gear swings etc., and now on the -8.

The jacks are bolted to used Toyota rims which make it easy to roll them around. The -8 is a bit higher so I'm planning to add some braces to make them less flexible.

Default Tie down rings

DO NOT USE TIE DOWN RINGS. I used the tie down ring for 5 hrs without incident, that is until last week as my post indicated. I wasn't even touching the plane when my ring broke. Luckily only a minor ding in the lower wing skin occurred. The nice design with the product that Walt is using is that it tightens to the bottom of the wing without marring. Without that contact the tie down ring, bolt etc. is able to break off. You can probably build something suitable with a bolt and nut but I doubt it would be as strong.

Default Jack Point

Get a 1-1/4" pipe cap drill a 3/8" hole in the end and put 2.5" X 3/8" long bolt though the hole put nut on and tighten nut. Now you have a stable place for your hydraulic jack. End of the jack rests on the bolt head nut on top. The jack can't slip out of the pipe cap. Only raise one wheel at a time or it will get real nose heavy. At least my 8 does.

Yes if you lift both wheels on the -8 you definitely need to tie down the tail...! I have a 500+ Lb tractor weight on a moving dolly that I use.
