<DIV><FONT color=#000000 size=2>Hello from Oklahoma.&nbsp; I've got a mechanical 
question for you.&nbsp; I suspect you Canadians will welcome the opportunity to 
think sailing, since&nbsp; your ponds have frozen over by now, haven't 
they?.&nbsp; Here goes....</FONT></DIV>
<DIV><FONT color=#000000 size=2></FONT>&nbsp;</DIV>
<DIV>&nbsp;&nbsp;&nbsp; I need to attach a couple of &quot;t&quot; tracks to my 
aluminum spars to mount a rigid vang -- one to the underside of the boom and one 
to the aft side of the mast. A couple of questions: </DIV>
<DIV>&nbsp;&nbsp;&nbsp; First, what is the appropriate fastners to use, machine 
screws or self-tapping screws? If I should use machine screws, will I have to 
tap threads into the spar, or will the machine screws create their own threads 
in the drilled hole? </DIV>
<DIV>&nbsp;&nbsp;&nbsp; Second, the track for the mast will attach over the luff 
groove; should I just screw the track into the back of the luff groove, or is 
there available some sort of tapped slug available that I can insert into the 
groove and then screw the track into? </DIV>
<DIV>&nbsp;&nbsp;&nbsp; Suggestions, please. Thanks a lot.&nbsp; By the way, the 
rigid vang is made/sold by Garhauer Marine.&nbsp; It's a <U>very </U>good piece 
of equipment at about 1/3 the cost of comparable Harken, Shaefer, etc.
