<BR><BLOCKQUOTE TYPE=CITE style="BORDER-LEFT: #0000ff 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: 0px; PADDING-LEFT: 5px">Now I remember somebody mentioning quite some time ago some site that had
<BR>plans for home made PCB etching gear that was pretty high grade...anybody
<BR>recall what site that might have been (I have all the plastic tanks, flow
<BR>switches, heating elements, liquid/temperature sensors, etc, etc I need to
<BR>build a lot of this stuff just lying around, thanks to a lot of scrounging
<BR>in
<BR>the bin behind a local medical dye laser manufacturer.)

<BR>Might as well ask a couple of questions since I'm posting...
<BR>
<BR>For those who have had success with printing to transparencies, what brands
<BR>of transparencies, printer, and toner are you using?
<BR>I have tried many kinds of film and toner in a Raven laser printer and have
<BR>never had any success. The toner is seldom opaque and if it is, the film is
<BR>sufficiently distorted from the heat of the fuser that it can no longer be
<BR>forced into flat contact with the board.
<BR>
<BR>I have also tried using translucent vellum but have never achieved adequate
<BR>resist exposure, even with very long exposure times. Is there a trick to this?
<BR>
<BR>For people milling boards, what kind of tool life are you achieving? Milling
<BR>seems like an attractive option to etching but small end mills are expensive
<BR>and re-pointing them seems impossible in a home shop.
