='all there means that if someone has job for tomorrow and his boss
has no money for a PCB house and the PCB house has a long lead time
and it happens to be a weekend and the job has to be done for monday
at 10:00am, then such a person may rund to Staples and buy HC200, for
$90, 30 sheets of paper by Gootee and be done with the PCB in an hour
because it was his first time. Otherwise he might be done with the
PCB in much less time.

=True, but there are many that rather pay for $90 for a laminator and
have boards done this evening. I am talking about the guys who work
in R&D at Langley, for example.

==that is a bummer. John Kleinbauer from www.kleinbauer.com once
said, and I paraphrase him with pleasure because he is a terrific guy-
that regretfully this (CNC) hobby does cost money. So does PCB
making. Time is money, and I would suggest taking a job for $5 an
hour and buy a laminator rather than do it and have an unpredictable
result- maybe, with hourly pay maybe 30 cents an hour, a year from
now. Just a thought.

==But there is, Dave. Remember, you still have to know how to use it.
The homebrew might mean 'homebrew laminator' or 'homebrew PCB'. I am
for 'homebrew PCB'.
Then you have to adjust it for thicker boards, instructions available
compliments of www.pulsar.gs, we cannot ask for more. I know that
www.pulsar.gs spent lots of time and money to develop that laminator
and conversion. He is a great guy by the way and we are just
benefiting from his enterprenurial skills. I like learning from
people- I di not come up with this combination, I just verified it
with my highly critical skills and lots of money. Maybe I should have
sold it on ebay?! hint hint.

==You are trying hard, Dave. I am looking at phenolic PCBs 8ea,
16"x20' and I am not sure if it was you or someone else who was
looking for them. I'll let you have them for $5 a piece+shipping, if
it was you. I don't recall anybody wanting to build a 3'x4' PCB using
TT. I also don't think that anyone might want to layout PCBs of that
size. And I don't think a Xerox conductor can do it either. I'll stop
here, because I think you meant something else. Also, that's why
people do cut their boards before laminating them.. However, one
thing is for sure, HC200 is for 8.5x11- they also have two other
sizes, they, meaning GBC.

==You are very correct. I tried them, all, spent lots of money on all
kinds of secret papers. I even tried to make my own paper and I tried
to coat it with dextrine. With all the expertise that I have on paper
manufacturing, it didn't help. Then I tried the paper by Gootee, from
Staples. You don't think I am making this stuff up, Dave? Thank you.
Please try that paper once with HC200 and let us know. I tried and I
almost fainted when I saw the result. I showed it to my friend and he
was sceptical before seeing it. I mean he was sceptical. When he saw
it he almost fainted. We've been trying to corral that rabbit for
long time, following every lead on this board, all there is on
internet, everywhere. And the only time it worked is as described by
me. It's that simple. You want PCBs at home and you don't want to
spend time following the false leads on this board that here is the
answer: HC200 and paper by Gootee. Why do you think I am so adamant
about this combination? Because it cost me a lot of money to be so
adamant about it. Mostly due to false leads on this and other boards.
leads are just that- leads: use it at your own risk, your mileage may
vary. But not with the HC200 and Gootee paper. This is it for
homebrewing PCBs. If someone finds a better method, better
combination, please repay the debt to this board, like I am doing and
post the results. I will be glad to try it. Also, it is possible that
by the time one makes to the store the laminators will be gone, more
expensive or redesigned. Paper will be on sale but it will be a
different kind. I have a stash of paper put aside.

==I knew you would agree with me, at least that much. My take on it
is that if one wants to start making PCBs in few hours and be happy
with it, this is what they should do.
Few weeks ago there was an article in Nuts and Volts about making
PCBs. I read that article and the author was rather ill informed, all
copiec from internet. Deception, deception.

People, please try that method and then comment on it. When Gootee
first mentioned that paper few months ago, I said yeah, right. I
tried all he suggested before and I had 70% success (once only
approching 90%) ie it di not work like he suggested. Then I tried
that Gootee suggested paper with that HC200 (that was my idea to
combine the two), my, what a change. As I rememebr he was excited
about that paper on his website, too.
Thanks for commenting, Dave. Mike
