Okay this has been mentioned before but they are going for $3 dollars this weekend at Office Depot, so I thought I'd post a heads-up.
This mini USB keypad makes a good rudimentary pendant; plug and...

Well . . . I have made a few compressors from odds and ends and as already said the necessary extras add up quickly. A cheapo from Harbor Freight would probably be a better value than something that...

TurboCNC gives the active low vs. active hi option in set up. I assume this is what you are curious about.
Active hi or low when switched in the "direction" check box will change the direction the...

It is relatively easy to switch out machines if plugs are used for the connections. Mach2 allows for setting up and opening in different configurations so the dual machine idea is workable. I do it...

Okay, I know this is getting stale, but I'll pass this on.
Mr. Slowinski sent an email that rehashed the above post, he acknowledged that he "had some homework to do" and was setting up systems for ...

Well the guy is slow to answer email but a call did verify that it is the math guy. How ‘bout that?

I told him about this thread and asked about credit cards, escrow etc. He said he would post...

Thanks!
Is this the same David Slowinski that does all the work in Chippewa Falls with Cray Computer, the Prime Number Guru?!
Well CNC does attract math nerds. . . :D

Thanks for the info!

Hi bfreesebfreese,
I am sorry if my doubts offended you, I probably am too quick to judge :o

I have emailed tigercnc through Ebay and have not received any info yet; a Google search finds...

There are simple "do not buy" filters for this kind of business.
Shipping insurance and credit cards.
Legit businesses offer and use both.

A business should be run as a business, especially when this kind of money is involved.

Money Order or Cashiers Check?
Never, ever pay someone you do not know that kind of money this way, there...

woohoo! Everybody loves a compliment :D
As Chuck said there are tons of ideas and pictures out there, mixing and matching ideas from what you find is often the best route to follow if you have the...

Yup, works fine; it does get warm but a stray computer fan keeps it from being burning hot. The wire is regular solid 14ga, if I recall correctly, it definitely was not anything special. The...

It will be well over $5000 delivered. Nearest port? Like Wilmington or Oakland, or nearest truck freight terminal.
Not bad but, there are no closeups, and no pictures from the back; the "Sunny USA"...

Absolutely no "wow" factor here but CNC sure made these tasks easier. Drop a sheet of MDF/ply on the table, press "Cycle Start" and come back later to all the slabs needed for the cabinet including...

Long answer:
I dunno, I've tried all kinds of paint for metals, from automotive to some of the new industrial coatings, then back to household yard furniture paint. I've found that for small jobs it...

Googling around.
Can't find the current import tax.

Fed is 18.4¢ / gal
State tax ranges from 7¢ to 32¢ /gal
National avg total tax 46¢ /gal
Currently gas is $2.50/gal
46/250 = 18.4%...

Okay, it is not elegant, but I just use the small relays to control the high current ones.

This is what I use, so far so good. Read the entire thread for updated info. The linked schematic has been updated to reflect the advice.

My sentiments are with Ken; the time it took to take care of the red tape did not make low markup items worthwhile. Too add even more complexity USPS does not offer the same services to an entire...

Had the same thing happen to an old reclaimed Hoover a while back, skate bearing to the rescue and a perfect fit at that. Sometimes we get lucky.
The bearing has lasted a few months now; sure beats...

In the picture is worth a thousand words department . . .
The red components are the primary force and load elements in the X axis; the closer these are clustered together the less leverage there...

Okay, so I am biased, but from my experience the two huge problems with homemade routers are the flexing of the materials made worse by the lousy mechanical advantages.

The best way to minimize...

As you said, the adjustment blocks allow for very easy adjustment, then the intermediate supports can be adjusted to position to eliminate sag and flex.
Likewise the intermediate supports can be...

Allthread is cheap threaded rod that can be found at home centers and hardware stores. 5/16-18 costs less than $1 /ft.
Acme rod costs a bit more but is still inexpensive. It is more efficient than...

Sorry to have missed this post. Warren, and Jeff of Xylotex, and I have straightened out the confusion.
The Solsylva table can work with Xylotex's steppers.
Thanks for posting Gerry!

When broke and just out of school my shop was the "extra" bedroom ( a bump in a hallway) in a 10 x 40 mobile home that I lived in. Most everything was done in the yard through the door. Ahh, good...

If the sign is of wood or plastic the time could be more in the range of 3 to 4 hours as you thought. There are so many variables, the sharper the resolution of the final product the tinier the cuts ...

In my opinion 3 point contact is definitely the way to go, the added cost is negligible. I am surprised that people are even considering 2 point on the X axis.
Your thoughts regarding the torsion...
