The fellow that did it said he wouldn't use the milling machine if he had to do it over. He said that he wore out the milling bits pretty quick on fiberglass and their cost ended up being more than having them done. There was also a pretty big mess to clean up too.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> Synth-diy [mailto:synth-diy-bounces@dropmix.xs4all.nl] <b>On Behalf Of </b>john slee<br><b>Sent:</b> Wednesday, December 30, 2015 12:15 PM<br><b>To:</b> rsdio@audiobanshee.com<br><b>Cc:</b> sdiy<br><b>Subject:</b> Re: [sdiy] Personal Pcb milling machines ???<o:p></o:p></span></p></div><p class=MsoNormal><o:p> </o:p></p><div><div><div><p class=MsoNormal>On 31 December 2015 at 06:09, <<a href="mailto:rsdio@audiobanshee.com" target="_blank">rsdio@audiobanshee.com</a>> wrote:<o:p></o:p></p><p class=MsoNormal>I believe it's a lot of work to master the many steps required to finish a board this way.

As you say there was a substantial investment of time, but only once while he was figuring out his workflow. He seems to turn them around fairly quickly now. It's no cheaper per area than OSHPark, Seeed or similar, but the turnaround time is plenty better. He's generally only doing one-sided boards, so no registration holes required.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I suppose with registration holes you could mill both sides.
