Wow, 3 meters! Another way I've seen is to use a cable. There are
pulleys at each end and the cable forms a loop. In the simplest design a
motor powers on of the pulleys. The cable takes the price of a long timing
belt. I've seen kevlar cord used for a cord and some steel cable also.

Hi Gene
I used the Machinist toolbox to figure out what sort of speed and feed I needed
but ended up running the mill faster (thought I'd read it should be 3000 but it
was supposed to be 2000). Typo error.
OK. So tool bit 0.09375. Two flutes. HSS. Chip load 0.00551. Aluminium bar.

Greetings all;
Having discovered the settings that control the low frequency boost in
this VFD, and having rigged a pretty dry misting arrangement, I figured
it was as good a time as any to cut the end panels of the box that has
the interface cards in it. These panels are about .035" thick, an

Thanks Andy and Chris for your quick response.

I plan to reduce the servos of the Y axis about 10 to 1 at least. I would
love to use timing belts and pulleys but I preffer to avoid all the trouble

backlash is a big deal. Maybe not so much with wood routing as maybe you
don't care about 0.1 mm error.But think about a how a backlash in
the 10:1 reduction translated to linear motion. Every time the servo
motor changes direction the cutter stops moving until the backlash in the
system is

Hello to all again!
I'm defining my router design after some months of inactivity. I already
defined my steel frame and purchased the iron to start building it. The
idea is to use the router mainly for wood and melamine boards. Eventually I
may use it for aluminum but that's not the main purpose o

Hmmm, I've never had tool slippage with R8 end mill
holders. I HAVE had slippage on a few occasion
Hi Gene,
Mines a different colour with a House Of Tools label but has a single phase 2HP
motor and is good to about 2950 RPM. It has an intermediate pulley and two
belts. I don't think it should be as noisy as it is.
