A few 10-lb sandbags on the HS and a padded sawhorse under the tail (low enough that the nose will come off the ground but not too far).

Use a Concrete Anchor
I drilled a hole in the hanger floor under the tail eyebolt and installed an expansion anchor. To lift the nose, I screw a forged loop over the bolt in the floor and use a cheap Harbor Freight mini-block and tackle to pull the tail down. I have a piece of chain with hooks on both ends to hold it down. You don't trip over the anchor bolt because it is under the tail. No danger of denting the sheetmetal this way.

Well, I crawled into the back of my fuse to install a comm antenna and whatta you know, the tail went down and the nose came up. No damage but now I have a tail STAND! Otherwise, like Mel I use an engine hoist to mess with the nose wheel. Expanding on this, it is not my engine hoist but a neighboring hanger partner's hoist. Between the airplanes, cars, trucks, boats, trains (well, maybe not trains but who knows) at the airport we are never far from hoists, lifts, jacks, fork lifts and any number of tools and helpers. Airports are great places.

One person push down on H-tail and another puts block of wood under the end of the nose gear. Takes 10 seconds and can actually do it by myself, if I have too, by pushing down and then rolling it forward a couple inches to get it on the block.
Push down on spar. Only takes a few lbs to rotate the nose up.

A few lbs?
10-20 lbs. That is a few. Your mileage may vary depending on your FWF installation.

An engine hoist will work but then of course you have to remove the upper cowl and then later put it back on again. Then there is the time consuming issue of gingerly rolling the rather cumbersome engine hoist into and out of place, especially if space is limited and other high dollar airframes are present you prefer to avoid. Tic toc, tic toc. By far the quickest, easiest one person way to raise the nose I know of is simply this:

Guess I'm missing something as it took 200 lbs of salt to get my nose off the floor, and that was still not teetering. I'm done.
Math
Weight empty: 1000 lbs
I have 250 lbs on the nose gear from my weight and balance
Moment arm from mains to nose is 55"
total moment to over come weight on nose (250 X 55) is 13750 in-lbs
Distance from mains to tail 110" (guess as I do not have drawing in front of me)
Weight needed to raise nose 125 lbs (13750/110).
OK more then 20 but less then 200. Seems less as pushing down from above is a whole lot easier then pulling down from below.
Yep on the "laying on it" to get it down...specially when it's your butt (not your arms) doing the work
Take care
