Drilling a composite helmet?

[Caspian]

I swapped an extra skirt for a helmet that a friend won in a raffle a while back. The helmet is a Rock Hedz Waterweapon, and now I have two of them. I'm thinking about putting a face bar on the second one and using it for creeking. I actually have an upside-down T facemask (think 1996 or so) from an ooooold helmet, so that would be the attachment. Is it a stupid idea to drill a composite helmet and bolt a facemask to it? I'm thinking it would be a lot cheaper than an FNA Extreme or something like that.

I hope it's not a stupid idea, cause that's what I did. Fortunately, I haven't yet thoroughly tested the ability of either the helmet or face mask to move rocks.

Follow up...I asked Mike Mather about this at the DSI class yesterday. He said that you should seal the insides of the holes with heavy nail polish or fiberglass resin, and if possible use rubber washers against the helmet in addition to the normal mounting hardware. He also said that due to the fibrous nature of the helmet, it would eventually weaken where the hole was drilled, esp. if subjected to a lot of from in the facemask.

I think I'm going to go ahead and do this with mine. It's an extra helmet and since I rarely flip creeking, I think as along as I don't crush the helmet in my gear bag, it should last for a good long while. I'll report back whenever I get it done.
