Why exclude collets in the comparison?

Ignorance/Stupidity you choose! Made the assumption that I wouldn't buying enough collets to bring down the price difference significantly.

I don't see the point of 1) and 2) since if you use a very cheap router to start with (suggest going to car boot if there's one near you and getting a variable speed one) you wont need to buy a Kress.

I did say I'd shot my self in the foot! Even in the light of my foot shooting proposed strategy I would like to know the answers just out of curiosity.

3) I've used the WC spindle at 5000rpm to drill aluminium with a 4mm drill, so although the torque is limited at that speed there's still enough to be useful.

4) It's just a matter of tweaking the settings on the VFD and having good cooling. Although it helps to buy a better (more expensive) VFD.

3) Ok the spindle I found stated 8000rpm minimum, I guess from this there are VFDs that do 5000?

4) More money = better, that figures

5) eBay

6) Yes.

5) As expected, is there a preferred sell like there is with Ballscrews?
6) LOL! Would you be so kind as to post them for me or PM them to me?

7) Here's one or two I made earlier:

I'd advise using 1/2" thick aluminium.

Nice work! Several leagues ahead of what my 43mm Hole drill and extrusion clamps will be! Once I know I can work my machine with the router, I'll make it machine its own replacement a new home!

Problem with that one is it only takes ER11 collets, so you're limited to up to 7mm cutters. That's one excellent reason to get the 2.2kW spindle - it uses ER20 collets which accept up to 13mm tools. Bear in mind several sellers here have used 'best offer' with these spindles to get them cheaper.

Thanks for the collet info, I have stored away for a later date.
