Chris, the slots do not have to be curved. They do not even have to be angled. The angle just provides a "wedge" to increase mechanical advantage in both directions.

You can eliminate the linkage and half the pivots, as well as increase mechanical advantage, by using slots in the outer ring. You can also eliminate the bearings by using the inner ring as a pivot. ...

Mitch, what kind of scanner did you use?

The cheek rest is not made on the Bot, but all the tooling and Kydex blanks are.

Make sure that both motors are actually turning. Additionally, you should make sure the motors are slaved and both are turning in the same direction.

The drill chuck would be a dangerous solution, since it's unlikely to be balanced for high rotational speeds.

I use stubby drill bits on the lowest router speed setting. A peck drilling routine...

Climb cutting.

Get a model of a spine and cast clear resin around it to produce the "suspended" effect.

Can someone post a pic of the OEM dust foot?

Thanks

Laser or water jet.

This a job for tracing, not probing.

Tracing a .jpg will result in accurate vectors and make for a much more efficient tool path. In addition, tracing will only take about 30 minutes.

Where is the work taking place?

Marty, when you say that you're pushing on the spindle, are you pushing up, downs or sideways?

The overall cut quality of your part doesn't look very good. It appears as though you have a lot of...

The thick sealing tape (>.125) is intended to be embedded in a slot cut into the table surface. When vacuum is applied, the tape is compressed until the machining stock is sucked down to contact the...

Can you post a screen shot of your toolpath?

The only people who get sued are the ones who can afford to pay multi million dollar settlements, or pay off the lawyers not to continue. Companies that have liability insurance are a prime target...

Here's the short version: If you increase feed rate by 100%, you reduce machining time by 50%. If you increase acceleration, you also reduce machining time. This assumes that your machine will...

Nikki,

I place hot pans on my bare maple cutting boards all the time. Doesn't seem to have affected them after years of use.

The gearboxes on the stepper motors have between .006" and .012" backlash. The PC router has .002" axial play and .005" radial play when new. You're not going to eliminate backlash by adjusting the...

I've had to replace keyboards. You might try that.

In regards to table top thickness: a thin top on a large table will support the weight of plates etc., but will look out of proportion in relation to length and width. It will also look cheap.

I have been machining Ipe pistol grips using carbide bits made for cutting metal. The bits work well and seem to last.

Apparently Ipe weathers well and certainly looks nice. Wear breathing...

You can probably use 3 or 4 small dust fans in series, about 30' apart.

Stan, for the "terrace machining" you need to use CAM software that allows horizontal finishing, as opposed the parallel finishing pass that you're doing now. RhinoCAM is the one I use, but there are...
