Putting a barrel on an AR using a standard barrel nut wrench on a tapco armorers tool. But I don't have a torque wrench. Its recommended that you go to 35 lbs, how do I judge that and how important is it.

There's really no way anyone can tell you how to judge that, since everyone's strength is different and will make it feel different to them individually.   Suck it up and buy a torque wrench, they do have quite a few uses and it would be a worthwhile investment.

It's pretty much impossible to tell you how it should feel. You can get a cheap torque wrench for about $30. I suggest you either do that or borrow one to save yourself trouble.

I use a Craftsman, but if your just doing barrel nuts I would look for a cheap one at Harbor Freight or amazon.com

I bought one a few years ago at Harbor Freight for around $20 or so, still works great. If you can, spring for a snap-on or craftsman at sears

Stand on a scale as you torque the nut. Torque=force (amt your weight goes down on the scale) x distance

Problem is, that force is modified by a lever rotating radially around a fixed point.  You'll actually get more mechanical advantage at certain points in the swing as well as modifying your body position in ways that might give false readings on the scale (Like leaning back to gain leverage on the arm).

That was funny.
And to think, we used to live in caves

Go to an auto parts store, sometimes they have tools that they loan out.
