I believe those "brass tubes" are for making bearings. Invaluable to someone who needs them and knows how to use them.
i was watching e-bay for a week or two, and similar items are selling pretty much by weight at scrap value and surprisingly even less. rather than try to find someone who will actually make something out of them, it's just a 3 minute ride to the scrap yard for the same money, no commissions to e-bay, no shipping costs to the usps.
What town are you from and how many pounds of brass do you have.
Might be good to keep around if I need to make something.....Chuck
