I see a lot of good tips here. Thank you.
Food for thought.... I have seen a lot of stainless steel lines get chafed and fail before the aluminum it was chafing really showed any signs of it. We were always patching lines on the A-10 but, to be fair, I must admit I do not know the temper nor the specific alloy of aluminum in those parts. I think it is likely those parts were harder than any aluminum parts in a Thorp but aluminum is very abrasive. Just look and see what the grit in sand paper is made of...
