Hammer weighting...Was Arbor Press

[Ric Brekne]

Hi David I.

I have had the same thoughts as Joe for quite some time.  Especially 
since I have several jobs here at the university I've had a chance to 
keep an eye on through some years. I've done no formal studies, but it 
looks like hammers leaded only halfway through develope loose centers on 
the opposite side of the flange as a result. Could easily be just me 
projecting a suspicion onto things... but then again perhaps not. Given 
the usage levels here at the UiB, and the amount of heavy play... well a 
more formal look see would have to be in order.

I dont find boring all the way through a problem. You dont need more 
then a very slight tap to anchor the lead in the hammer.  In fact a good 
way to get the feel of how much you actually need is to use a small 
piece of lead that will fill up only half the hole and tap it only very 
lightly on one side, then flip it over and tap the other side... repeat 
until you cant move it in the hole anymore. Takes no time to get real 
quick at centering the lead in the hammer.

Cheers

David Ilvedson querries:

What does the List think of 1/2 way holes rather than all the way 
through? 2 1/2 holes equals one through for about the same weight...."

David,
I should think that the 1/2 way through would put the hammer in a bit of 
a inertial imbalance. <G> (worth a thought, I think.)
