Have you made an air deflector for the bottom of your router ?

One of those small plastic 6 inch frizbees will work. Hold it on to the router with a few pieces of some very light chain.

Do you have a photo?

With plastic, the bit manufacturer might be your best bet on information on the feeds & speeds.

So is a 5 hp spindle more for heavy duty cabinet work ?

What determines if one would need a 2, 3 or 5 hp ? Does it make a difference if one has an alpha or not ?

The aluminum below / for holding the track...

Seems to be only 6 chains left at that $25 price.

When you install it, move the Y to the zero position before attaching the stationary end of the chain ... that way you can do in right the first...

I thought I should at least post a photo of the final carrier chain assembly.

Ordered this a few days back from Amazon and it arrived today..

I can only say it is of Excellent Quality for those of you who might need a 3 meter piece of it for your Y axis.

As before, it might be best to just mark the hole locations with a router and drill them out later...

The router is made to cut sideways not up and down.
