I'd just chuck em, in the back of the cupboard for a rainy day! or if i really didn't like them I'd give them to my Neighbour!
Good luck! I'm look forward to seeing it!
If you need any parts I have some you can have:
hazel drills (very dry!)
Poplar (which was cut recently needs drying but will do you well).
and some flints with dips you could use as a bearing block.
And remember the bow, don't make it too springy or the string won't grip the drill!
Any problems just ask!
Yeah made the Bow today kinda snapped the drill i had set up
got a couple pics i will post soon
