No worries TGR... I often resemble that anatomical feature myself, and have been told so... unequivocally, more than once..
Here is a pic. of my improvised headset press, unassembled.
I actually have about three dozen of these that I made up as woodwork clamps a few years back. It was only when casting around for something to press a headset home that I realised one of them would be ideal. This one is now my dedicated headset press, given that it is likely to get a bit greasy in that application!
The studding is M8 I think, but anything (within reason) will do. You may need a longer length for big frames. A couple of washers and nuts, one of which can be a wingnut if you like! The wooden cylinders are 1" thick and 1 3/4" in diameter. Best use Hardwood if you can. If you were making these you may as well make them 2" diameter... 1 3/4" is just
big enough on my headset(s). These wooden bits are drilled to be a loose/sliding fit on the studding. Really there is no need for them to be cylindrical, or any particular thickness.. Large metal washers would do just as well. FWIW I didn't even need to use a spanner with this to press my bottom cup/top race (one at a time) home, but those cups are old...YMMV.
Just improvising, you know... I've used a sash-cramp as a headset press in the past. A King-size G-cramp would do it too..
