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

[Jonathan]

I don't think Jonathan can complain considering how much he paid for the router as it was never intended to be used as aggressively.

Yes exactly, it was only £8 or so from the car boot sale so it's not a big loss. I would have liked it to last a bit longer though as now the router might be out of action for a while whilst I save up/sell a few bits for the proper spindle. Maybe I can get a loan from the Bank of Mum :lol:. I just wish my chuck for the brushless motor had arrived - it's been ages.

Increasing the effective length of the cutter will exert more bending action on the spindle, which now seems to be bent. This is in an even more dangerous condition and the end could just fly off with serious consequences.

I'll check that with the indicator today.

Jonathan regards to your original question i would stick with 1.5Kw as your machine has some flex issues which you yourself have mentioned, going for an even more powerful motor will allow you to think you can push it further than it wants to go.

Ok, I will do. It's still twice the power of my milling machine and I've never run out on that. As you say the router is not as rigid as the milling machine, so I can't see it being able to use more power. I may well lower the gantry to help with the rigidity issues.

HSS cannot bend, only break that is what makes them a safer bet than an extension made from anything other than HSS which Trend will not make that type of extension as it would be dangerous.

I'm trying to machine a block of MDF thats 3 sheets of 18mm glued together. I need to cut to about 50mm deep...maybe I'll have to do it one sheet at a time then glue them together.

I checked my router with dial indicator. It's now holding the cutter at an angle such that there's more runout the further you get from the chuck. I'm not going to try running it like that - clearly not safe.

I've just looked it up and found that the ER11 collet chuck will only hold up to 7mm diameter. That's not good enough for reasons detailed in the last few posts! I'll have to get the 2.2Kw spindle as it has ER20, so up to 13mm. I can't accept only 7mm since to make wind turbine blades, the main reason I made this router, I will need cutters protruding perhaps 4" from the spindle - unless I use A axis.

You can get bits designed for slot mortising - see the second cutter down at http://www.amanatool.com/bits-fv/45500.html or http://www.machines4wood.com/mall/pr...sargeant/CM103

I've used them on a manual machine to cut beech and they worked well but you need a light final finishing cut due to the flex.

On the other hand, one of the big advantages of CNC is that you can stand well away from the scene of the accident

Problem with standing well away means I'm too far away from the stop button!

Those cutters look useful, but still a compromise. I'm cutting 50mm deep to clear the material around a mould.

A secondary emergency stop button?

Maybe a dead mans handle style one so all you've got to do is drop it as you run away :-)

Good idea.

Jonathan on a machine your size you just need an EStop on every corner. Hitting the button should cut power to everything except the PC and you should not rely on the PC to do this it should be hardware based.

That collet extension is similar to what I made, except I held the cutter in with 2 grubscrews to keep the diameter down...the whole idea was to extend the cutter without the extension colliding with the material above.

Yes I'll sort out the Estop buttons soon. Two should be enough considering where I'll be standing...
