I have recently obtained a Bridgeport Boss and I now need to sell my Sieg Kx3 CNC. Running Mach3 on a Mini PC running Windows 10 and an Ethernet Smooth Stepper. I replaced the original C11 style interface board with a C25 Breakout Board with screw terminals. Wanted more inputs for limits and...

I recently found this site having small fasteners - Hardware - Machine Screws - Page 1 - orchidsound electronics - for example - 100 2-56x3/4 Phillips head screws $3.65. They have a nice collection of small inch and metric screws and nuts, all at very low prices. I have looke other places and...

I have a Hardinge UM from an old Navy vessel that is missing the power feed. I have an idea of the size to the worm wheel and wor. It would appear that the original had a 2 start worm and 30 tooth wheel. Bore on the worm was 5/8 and fit over the table lead screw with a key driving the screw...

Recently got an Enco 12x36 lathe and I would like to be able to use collets in the spindle. I know I can get the whole setup from Grizzly, but like many others, the money can sometimes be in short supply and I think that I can reasonably make the rest of the parts save for the #5MT to 5C adapter...

Decided to do some 3D modelling - Starting with Elmers #1 Didn't include fasteners and such. Have the Drawing in AutoCad if anyone is interested. Decided to draw it up because the pictures with the original download didn't show up very well, and sometimes a good rotated view can make the...

Picked up a new toy this weekend. Esco Marine Salvage at the Port of Brownsville had a former Navy Hardinge UM Universal Milling Machine. I had been sitting outside for a while (no rain to speak of for the past 18 months except for the past month) so after cleaning up the surface rust it looks...

I am neding some 1/8 endmills and not wanting to pay a high price for something I know I am going to break (dmb thumbs on the CNC...). I got my last batch from a vendor at NAMES a few years back and have managed to bust the last one. Those I got for a buck a piece (plus the drive from South...

I have been working on a VBA application that runs inside ProgeCAD or AutoCAD that helps write CNC code as you select eh elements to add and make a few descisions along the way. Is there anyone out there who might be interrested in playing with it? At the present time it is basically 2D with...

Just got a new KX3 CNC mill here in my room at the school where I work. Been getting it all setup and working and hope to make some real cuts tomorrow. Had to play around with the configuration so that it will display on inch and I am hoping I can get some more RAM for the computer so I can play...

Here's another book I found on Project Gutenburg - Oil and Gas Engines Simply Explained by Walter C. Runciman dated 1905. Talks about the old 1 lung gas and oil pumpung engines with lots of good illustrations. While not dimesioned, the drawings give enough detail of how they did it that one...

Found this browsing through Project Gutenburg - The Packard Aircraft Diesel of 1928. An interresting history, description and a few good pictures. http://www.gutenberg.org/files/31023/31023-h/31023-h.htm Pete
