I need an effective and non-damaging way to hold a couple of older Shimano 7 speed hubs so that I can wrench off the cassette bodies. The hubs are new old stock. I don't think I am dealing with a corrosion problem as the grease is perfectly clean and the hubs have never been used or stored in a corrosive environment. I want to take off the cassette bodies to perform a swap of HG and UG bodies. I have the required 10 mm Allen wrench, but I can't seem to find an effective way to hold the hub in the vice. I am currently trying to hold the hub in the center with wooden pine blocks that are lined with inner tubes. The hub spins before I am able to apply sufficient torque to unscrew the retaining fastener. Please share any effective methods.

I did the same swap last autumn and had no such problems. The hub is built into a wheel and I simply held the wheel with my left had and wellied the socket wrench with my right. My hub was 14 years old at the time, had done thousands of miles with only regular bearing maintenance. Are you using a sockect wrench or a smaller allen key ? You probably know this but it is a regular right handed thread so turn anti clockwise to undo.
I must confess I was expecting the job to be much harder than it was. My old body came off easily and the new one went on with no compatibility problems. I have not fitted a HG cassette yet but intend to do the 8 of 9 on 7 trick on this and my tourer (which will actually be 8 of 9 on 6).

If you won't build them into wheels for this purpose (you could just build the wheel you'll eventually build anyway), maybe you can screw a piece of wood to the NDS with a thin screw in each hole. Or, a couple pieces of wood with cutouts for the inside of the hub, properly thick to screw both DS and NDS into... -- Rick Onanian

Use about 6 spokes and lace the hub into a rim. Then use your 10 mm hex key.

Lace it to a rim with a few spokes; hold the rim.
Ditto here. I did this a little while back when I was swapping cassette bodies between bare hubs. You need half as many spokes as a whole wheel- 18 spokes and a 36-hole rim in my case.
Remember that you'll need the same thing to tighten the body on the hub.

I was trying to avoid the obvious. I even bought a special set of jaw covers with rounds in it. It came frome Sears and even has magnets in it to keep it on the jaws. However, even with this nice extra, I still couldn't get a good enough purchase to hold the hub in the vise. I finally gave up, built the wheel that was to receive the cassette body transplant, then partially laced the donor hub, and finally made the switch. It was easier than I thought and certainly made the vise routine look like "What were you thinking?" Thanks to all who put in their convincing words of experienced of advice. My old 7 speed carbon fiber bicycle is going to enjoy it's "new" HG cassette rear wheel.
I have started a collection of 7 cog freehubs because they are not making them anymore. Take some string and run it through the spoke holes and tie the hub down to something a piece of wood with two holes works great. You only need to use one spoke hole but one in each flange works better. I use a steel railroad tie plate with some newspaper between the hub and the steel. This does not damage the hub the stresses are not that great.

Take the hub and the wrench (I assume here that it's a bit that fits on a ratchet) and run down to the nearest car repair shop. Ask them to use an impact wrench to undo the retainer for you. I've taken these out with a 3/8"-drive impact while holding the hub in my hand; no vise needed.

Build a half a wheel. Doesn't have to be good, accurate, fancy or even correct. You can use an old rim, spokes and nipples.
