You will know.
Trust me that I have not had a true good moment to go over to my grotto and weigh the thing. It takes more time than most would think to do it correctly. The scales are not that tough, but rather sensitive instruments.
Scared! I know that its not as light as it should/would/could seem. I have not touched it even with my eyes. I don't want to fool myself either, but the next weight loss phase after I weigh it and display it here is gonna be extreme within my constraints of a full metal skin. I've pushed it a few times and its hefty. No, I do not have a spool in it, though some times I wish I did for the weight savings.
Who knows 440, you might win the prize.
In the end, I'm shooting,hootin'for a high 20's all steel(*cough*) B-body street car.
Will be back soon, soon, soon, soon, soon....................
