Where's the cheapest place to buy a Kress 1050?

Yes it would cost more but cheaper in the long run. Like a lot of people they use or buy a cheaper option to start with and end paying out again for something better....save your pennies? all good things come to those that wait :-)

Hmm, I thought by getting a Kress spindle I would be getting the better option! At the moment I'm using a router that was £6 from the local car boot sale. I guess I'll have to try and save pennies...that's a LOT of pennies though. I got my milling machine for £300 and yet that spindle costs a similar amount, which is more useful...if only my student loan was bigger!

Its £128 inc vat plus shipping but i agree with 2e0poz that the Chinese spindle would be the better option in the long run.

Why, well the minimum speed is 5K on the Kress but i read on the zone of people using the Chinese spindle being used at 200 RPM

also the speed would be fully adjustable within Mach UNLIKE the Kress

Also a lot quieter than the Kress

Thanks for the link, though I think you've both persuaded me now. Persuaded me to wait at least.
I'm not too bothered about <5000rpm as my brushless motor spindle will do up to 6000 at much higher power. Having said that I don't know what the runout will be like. Maybe I should make it, flog it and then buy the spindle you're suggesting.

What power rating do you think would be suitable? 1.5kw? I take it they're rated by input power, not output - if so what is the efficiency?

£700 for a Bridgeport sounds good. They had two at school (sold 1 last year ), no comparison between them and my milling machine...I'm jealous!

My mill was 300, plus 20 and 2 cups of tea for them to deliver it. Another 20 for a massive milling vice, and yes...lots lots more on tooling. Not bad considering it's £800 new:

Well i would go for the 1.5KW as that is 2HP like i say someone used his at 200 RPM and they can run up to 25K also the higher the HP the more expensive the inverter.

I might be buying one of these sooner than I thought. My really cheap router stalled today for no apparent reason, and emmited a little smoke. It still runs, so the motor is fine but I think the collet chuck is damaged. It's not holding the cutter on centre now.
When it stalled I couldn't stop everything fast enough so it bent the 8mm steel bar that I was using to extend the length of the cutter - shows how powerful the steppers are to do that!

Anyway, I think I'll get this one from this seller:

It's the cheapest I can find. He's not got much feedback though...

Maybe get a 2.2Kw one:

Or is that overkill?

Does anyone here have a dimensioned drawing of one of these spindles? What does the 180mm length correspond to exactly - as in does it include the chuck/wire etc?

Jonathan i think you need to learn some safety. Extending the lenght of the cutter using an 8mm bar seems an extremely dangerous thing to do. You are not wearing any safety gear (Full Face Shield) would be a good idea and ear defenders, i know to my cost how stupid it is not to wear ear defenders .

My guess is centrifugal force took over and bent the bar not the power from the stepper,there is a reason that the cutters are not too long, and that is for safety/stability reasons. I'm sorry if i seem to be having a go at you personally but you seem an accident waiting to happen.

So this rant is also aimed at the people who think machines running at high speed are safe, they are not especially when you modify them to be even more dangerous.

The last thing people on here want to hear is of you having an accident or anyone else for that matter.

Rant over
