Just a quick observation about post #63: as we all know, a resistor labelled 560 IS a 56 ohm resistor:
The final digit is the number of zeros after the first two digits; 0 means no zeros, so the...

Dear John:

Thanks a lot for another prompt and incredibly detailled and complete answer.
As always, you are very generous with your time and expertise for the benefit of
us beginners.

Dear John (microcarve):

Please, allow me to return to the distant past (04-12-2011, page 58, post #692).
I was reviewing this fantastically useful and informative thread and found there...

Dear John (microcarve):

I've been considering the possibility of a "steel A40", ie: an A40 in
which the MDF parts were replaced by steel plate, say 1/2" thick.

I know it would be heavy - so be...

Thanks for the explanation regarding the touch-panel.

Also, thank you for Melvin's pictures - I love golden retrievers. Please
post a close-up, if you have - I don't care if it is...

In post # 2 you mention:

"el cheapo 15 in lcd that I converted into a touchscreen"

Could you explain how did you do this conversion? I'm quite interested
in doing something similar...

Dear Mr. McKenna:

Thank you so much for your kind reply.

I'm certainly interested in your offer: You could post a link here or PM me if
you prefer

Dear Bob Shaw

Thanks a lot for your kind reply - Now it makes sense... I had to idea
the tool doesn't rotate, specially after seeing it mounted on a router...

Nelson

Dear Bob Shaw:

I enjoyed your video at http://www.dragengraving.com/ and am interested in one of
your "drag engraver"'s. However, I have a few doubts and questions, if you please:

- I...

Dear Mr. McKenna

Sir, you're a great engineer and a great artist - actually, this is a pleonasm:
great engineering is mathematics+physics+a great dose of art. Just look
at a SR71 - a work of art...

Dear Harpye:

Absolutely amazing craftsmanship - Could you tell us more about the
machine you're routing this with? A few pics and specially a short movie
of those "spiderweb plates" being routed...

Dear John (microcarve)

I'm in love with your A-10, and would order one in a heartbeat, if I lived in the USA.
However, down here, a heavy and large box like the A-10's would cost me something...

This discussion might give you a few ideas:

In particular, this seems to be an interesting homemade contraption:

Dear John (microcarve):

Congratulations on a beautiful, well built machine...

Would you be willing to disclose a little more about this router:

.size of the guiding rods
.type of linear...

Dear MadMax:

Thanks a lot for your kind and thorough reply.

I'll use your method... of course, I'll also wear my faceshield and welder's apron and
gloves - you can never be too careful...
...

I have several used shock absorbers that were replaced from my cars.

They have beautiful chrome shafts that could be used on a CNC router - at least in the
z-axis.

But, I hear they are...

I confused citric acid with acetic acid... sorry... it was citric acid all the time...

Nelson

Dear diyengineer:

I'm amazed with the results you've obtained with your acetic acid bath
to remove surface rust, and I'd like to use it on some parts I have.

So, I searched about "acetic acid"...

Dear serriadh:

Thanks a lot for your great contribution, particularly your summary and the explanation by Gary Giddings.
I understand now much better how a threading dial works, and can go ahead...

Just a crazy idea, if I may:

I bought a very nice old lathe, but it came without a threading dial - I think it never had one...

This got me thinking: could an electronic threading dial be...

I understand... Thanks a lot for your attention.

Nelson

Dear RomanLini:

Congratulations on your beautiful and original machine... I'm particularly interested in the nuts:

"The leadnuts were cast from a special slippery plastic that I work with and...

Adam:

Would you or your friend be willing to post pics of the finished model? It would be awesome! The Dora/Gustav was so huge that even a 1:35 scale model will be quite big...

Nelson

Hei - may be this is not just a curiosity for the rest of us...

I think every amateur CNC'er dreams of playing with a 5-axes machine, but very rarely
have I seen a working sample here on the zone...

Dear Mariss:

Thanks a lot. I'm already sitting on the stands...

Nelson

Dear Eclipze: Please forgive me - I'm not hijacking your very interesting thread,
which I'm following closely, but in face of posts #66 & 68, by the
great Mariss, I...

Dear Eclipze:

Fascinating project - you must be a master machinist, with a very well equipped shop-
quite out of my league, but I'll follow your progress closely, as there will be a lot to...

Dear Casainho:

Thanks a lot for your kind reply.

Unfortunately, I am far away, although we speak the same language...
MakerBot store was a great tip. I'll try them, since they say they do ship...

Dear Casainho:

Congratulations on your 3D-printer. Very impressive results...

I'm also thinking about this, but my main problem is how to get the supplies: what
kind of material are you...

Beautiful design, edward.ford.

Do you intend to sell the plans or make them available somehow?

I would be interested...
