Bosch Colt Runout

The Colt router that I purchased from Rockler with my Pro Plus had a high runout, as much as .006". I read about an alternate collet and nut design for the Colt on this forum which is made by PreciseBits.com. They have a package that includes a 1/8 collet, 1/4 collet, nut, spanner wrench and a colle...

Re: Pro Plus Table Flatness

Thanks for the responses and your findings. As I previously stated, I am a Mechanical Engineer, so I took some measurements, made some assumptions, and did some calculations. Here's what I got. Measurements: The two round steel bars that go across the gantry (X direction) are 31 inches long and are ...

Re: Pro Plus Table Flatness

Here's what I did so far: I decided to use a square aluminum extrusion, 3/4" x 3/4" x 1/16 wall. The square shape makes it very stiff and it was easy to drill. Also, it fit over the Y-motor with no alteration. After I bolted it to the slats with it clamped to the base, my indicator told me I needed ...

Re: Pro Plus Table Flatness

Mike, Nice job. My table mapped out a little different than that with about half the table, X0 to X14 within .020, and X14 + gradually falling off to a minus .060. But I do like using the aluminum angle to get the flatness across the X. I got the indicator and the angle and some time tomorrow to try...

Re: Pro Plus Table Flatness

Yes on the individual slats reacting, well, individually to the clamping pressure. If the supplied clamps are used they must apply pressure over the same slat that they are mounted on or you can get a major deflection from two adjacent slats. I guess that's why so many have come up with different cl...

Re: Pro Plus Table Flatness

An update. I got a Federal electronic indicator with resolution to .00005" and mapped my table. Starting in the front left corner, I set 0,0,0 and zeroed the indicator after clamping it to the router holder. I moved across the front indicating about an inch from the front of the table. I moved about...

Re: Pro Plus Table Flatness

Jim, Thanks for your information. Both practical solutions. I want to do some measurements. I actually laid a good flat straightedge across the X-plane and couldn't see any gaps. So I think a few measurements will confirm if the Gantry is parallel to the bed. The aluminum table should be pretty flat...

Pro Plus Table Flatness

First off I've had my machine for a couple of weeks now. Only one issue it was missing the Router hold down collar, but Tim Owens took care of that immediately. I've only cut about 3 jobs so far and I notice that the table goes out of flat about halfway across the X-axis. It gets lower as X increase...
