Inch Pound to Foot pound ?

So, 3 ft-lbs = 36 inch-lbs.
The nuts for your Gold Valves need be barely more than snug at 30-48 in-lbs. You may want to apply a drop of low strength Loctite to the threads to help prevent loosening. Make sure it's dry before filling the forks with oil.
FWIW, I believe Sears has a model (Digitork?) that goes up to like 250 in-lbs, seems to be reasonably accurate and fairly inexpensive for the layman that doesn't make his living with it or require highly accurate torques.

I forgot to add that I talked to an x-motorycle mechanic and he said that he did it many times and it gives you the torque specs so you dont strip it. He said just what you said about just barley going over snug.

You can virtually tighten it finger tight and then snug it with a deepwell socket by hand, without the ratchet. It really isn't that tight.
A drop of low strength threadlocker on the post will help prevent it from loosening. Again, let it dry before assembling in the fork. Some people don't like this because they're afraid it might snap the post when removing the nut.
If you use a small drop of low strength locking agent on the post, you shouldn't have a problem
I never have!

I suggest the Craftsman 944593. It's a 3/8" clicker type that goes from 25 inch-pounds (~ 2 ft-lb) to 250 inch-pounds (~20 ft-lb) which pretty much covers 75% of the torque specs you'll use on a bike. Craftsman isn't Snap-On quality, but then again, it only costs about $70.
That's the one I was talking about!

If you guys are talking about the upper fork pinch bolts, I was told by a good moto mechanic that the reason for such low tork is so the fork is not deformed out of round or compressed in any way to allow the internal parts to be free to move in the manner designed. This is because the fork tube is very thin. Not necessarily to strip the threads.
I assumed when he was talking about Gold Valves and 30-48 in-lbs, he was referring to the nut that holds down the shims on the base valve assembly.
Race Tech called for 48 in-lbs on the last set I saw.
Most of the triple clamps I've seen call for about 14 ft-lbs on the lower and 16 on the upper. This is a lot more than 30-48 in-lbs!

Be carfull, I snapped a base valve tower once, the night before a race. NOT fun. You get to replace the entire base valve.

No one seems to have one to rent or buy really.
Pep boys rents them . . . you pay the $40 purchase price, then return it for a full refund minus the local sales tax.
