Ideally, Having the block at some consistent resonable  MC level for fitting, boring & stringing woul= d be ideal.</DIV> <DIV>  The way I see it is that the end product will live in an indoor environment with RH levels in the mid 4o% in my area. So I want to work with= the block in this range.</DIV> <DIV>  Drying down the block can take a good long time because of it's density so don't hurry. There is a MC chart in Hoadleys handbook which relat= es temp & R.H. to end MC.ie 80degrees at 20% R.H.= 4.3 % MC. I'm guessing= but this is close.</DIV> <DIV>   Dale</DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: blue 2px solid"><= FONT style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size= =2>The humidity in my shop today is 63% and higher than I<BR>usually try to keep it.  I'm getting a block ready,<BR>the flange fitting is done; What w= ould be the best<BR>level for the humidity to be and for how long to<BR>enhance= the drilling/pin torque outcome?
