What is it, Icarus, that so makes you want to radially lace an old hub, one for which the designer and mfg reduced that all-important "rotating mass" by placing the spoke holes as close to the edge as design calculations and experience told him/her tangentially laced spokes would permit, without tearing the holes?
What is so odd to me about radial lacing is how much of the safety margin is reduced.
Seriously, I'm interested. As I am with the historical drillium phenomenon. Have hammer: will pound. Have drill press: will lighten. With spare time, I am actuarially reducing my lifespan polishing those rims and hubs, rather than taking the risk of weakening them.

-oOo- My radially laced 28 spoke Mavic OR10 front wheel held up under time trialling conditions (around 1982), but after some retensioning (by my very expert wheelbuilder, he liked tight wheels) the rim started bulging and cracking around the spoke holes. I used 32 hole OR10, (2X cross laced) wheels for some nice tarmac criteriums, but was never really happy with a feel of unstability, compared to GP4's. I weighed (and still weigh, hehehe) around 180 lbs (just under 80 kgs).
