I'm using Artcam Pro 8 and Mach2, and am now trying to create g code for a rotary axis which spans X and unwraps in Y. The rotary axis works great in MDI, but g code files have y values that are way...

What a quick, inexpensive, and functional solution to your problem. Thanks for sharing. For my cnc router enclosure I lucked into a pickup load of 4" thick 4 x 8 foot rigid foam aluminum faced...

When the parts in a design are cut from thin sheet and include holes, sometimes it helps drilling the holes first, then securing a screw in each hole, then cutting the outlines. Be sure the rapid...

Thanks, this is just the information needed.

Thanks, mactec54. Checked out your link to Automation Direct 120/230v inverter. For a little more money, 230v working voltage, a manual that actually is comprehensive, and parts and customer service...

393988 Now I'm really confused. As you can see the spindle of interest has 4 pins. Some of the listings for this model actually state that the inverter output is 3 phase 100hz to 400hz at 110v. Of...

Don't by the 800w 120v spindle, get 800w 220v spindle if this is the size you want, you can get a VFD Drive that is 120v input and 220v output for your spindle this is much better to do it this way

Thanks guys for the spindle recommendation and the connector information.

I need a source for the electrical 4 pin connector that screws into the top of the high frequency spindles such as those made by KY. Someone posted the source for waterproof ones recently, and...

I'm no expert, but some things that worked for me. For the Y axis gib that slides out: At least one of the setscrews should have a dimple on the back face of the gib it seats into. This setscrew will...

Check out this video which explains the whole process in detail and in plain terms. A big part of doing this right is heating both pieces to full temperature before adding the rod. That was my...

When I did a heavy lift like this by myself luckily there was also a chain hoist available. I looped a heavy chain around a ceiling beam and attached the chain hoist and made a straight pull upwards....

To double nut properly, first tighten the original nut until there is no play and no binding. Then put a wrench on this first nut to prevent it from moving (and also make sure the shaft stays...

I built my own power supply from parts without knowing much about electronics. If I can do it, you can too. I used this diagram from PMinMO's excellent site and it works great.

Simple Power Supply

The handpiece on your machine is a clone of a Foredom #30 with a 3 jaw Jackob's chuck held on with an interference fit similar to a Morse taper.. As mentioned it is not suitable for milling.

The small carbide drill will not dissolve, but will fall out when the tap dissolves.

When I replaced the balls in one of my ball screws I purchased the new balls from a company on Ebay. They had balls in increments of 0.0005 above and below the 0.1250 standard size

zoefie, For what it's worth, here are some quick and dirty methods I use.
First, if possible cut your designs from vector art which has smaller file size, cuts much cleaner, and can be easily...

I run a Hitachi M12VC also and find it an excellent choice. It is quieter than a laminate trimmer and does not lose rpms under load. It has very good speed control built in to it and a soft start...

I have an HP scanjet 4400c, but other scanners are similair. What I do is make a preview scan, at which point it asks if you want advanced preferences. Click advanced and all the options are...

Sounds like you are using blue layout die which is made to dry fast to a very thin film to allow it to be scribed. It's just like water, or even thinner.

You should try Dykem High Spot Paste which...

Have you considered making the mold from aluminum? Easy to machine and it should hold up for extended runs. You can also water cool the mold after each pour to reduce cycle time(like they do with...

I'm a rookie, but I'll throw this out for whatever it's worth. I have only had slight experience doing this, but when I did it turned out nice and sharp.

First I ran the art through the scanner as...

I have the N model. I looked up the W model and all specs are the same as far as I can determine. Be sure to check those 9x20 sites as well as the handful of yahoo 9x20 sites on the web.:cheers:

I bought that model from Jet 18 years ago and have been using it in my business ever since with few problems. It cost me about $1350 if I remember correctly. I think it's a great lathe for the money...

Check out this site which has free software to convert 3-d files to sheets of material so shapes can be cut out and folded into true 3-d objects. The fold lines would be cut part way through and the...

I would go for it if you could get it cheap (that is, for a little above scrap value) . then you can sell it for scrap if it does not work out and only lose a little. Sounds like it would be more...

There are several ways to reduce and/or eliminate the oxidizing scale that regular heat treating produces. Hardening in a liquid salt bath eliminates the problem, but may be as expensive as a...
