Neat idea John ! Not something I'd like to try to knock up whilst out in the woods ( it takes just too much effort and sooo much charcoal to smelt decent steel :lmao: ) but as most of us carry our kits made up, including our favourite bearing blocks, I think that's an idea that will catch on fast witha lot of guys.

Am I right in guessing that your set is hazel drill and lime hearth ? Good combination if it is.

The bearing will be specified for a reasonable load on a steel axle probably at 1500 or 3000rpm. Bow drilling won't give it any abuse. Once upon a time I was after an axle for a Trebuchet and tried a bike sealed bottom bracket. The bearings were a little tight so I thought it could do with a little breaking in, so clamped it up in the pillar drill and left it at 1000rpm for an hour. Horribly over speed for an hour and no sign of wear at all. Sealed unit bearings are brilliant.

Great idea, sorry but I'm going to have to steal it!

Although this sounds like a good idea, don't you think it takes away the theme of ancient fire lighting methods.

Stick to using a bowdrill as is without modernizing it, your bound to get more satifaction from making fire by friction than:
'Oh, I made fire by friction with the help of sprucing up my bearing block with a bearing, maybe next time I'll use packing grease to make it a little more slicker and maybe I'll dip the tinder bundle in a bit of petrol to help it catch from the coal!"

IMHO some things should stay the way they originally are.:22:

I have tried using cord made from palm leaves and it worked quite well! How about you?
I also use hemp rope most of the time too. Which I believe is very natural!
