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

I underestimated how much extra force it put on the cutter having it 50mm further out.

I've used the same 'extender' in the milling machine lots of times before, admittedly at a lower rpm - yet similar feedrate so probably similar cutting force.

I was wearing saftey glasses and ear defenders - got the latter for Christmas! I agree that one should be conscious of saftey with these things...
'accident waiting to happen.'

Is there something else I've said that makes you say that?

My rant over...

Your youtube videos show you holding parts while being routed and about to break free from the surrounding material, do you call that safe ?

50mm extension is just way too long and are you are gonna admit its made of soft steel

Here is a pic of an extension i made for a Makita 2HP router , on the left is the original nut and on the right is the extension, the extension is the same diameter as the shaft so SAFE anything less is dangerous.

New rant over.

I agree that's not the best of ideas - I don't think I'm the only person on youtube guilty of that, though that's no reason to do it. I was careful in that case not to put my fingers close to the cutter. I made sure the last cut was very light and plenty of clearance so little chance of anything unexpected. Generally I do put tabs on the parts which are routed out at the end to avoid that, or in the case of PCBs stick them down with double sided tape. On the milling machine I've put a bolt through the part in the past to stop it escaping.

It was made from 316 stainless steel (not nice stuff to machine, work hardens), though I'll admit that was mainly because that's what I had at the time. I made it 8mm as that's the biggest collet the router can take. The nut and collet are separate parts on my router, so it would be tricky to make a mount like yours.


The safety things I won't have much idea is where there's a difference between manual and CNC machines since we only had a very small CNC router/engraver at school...

Jonathan there is a saying expect the unexpected. Another is act in haste repent at leisure.

Ask Trend Routers if they make an 8mm router cuter that projects 50mm from the collet and see what they say. I have had a few close shaves myself so i know what i am talking about.

Point taken, I looked a couple of hours ago and only found one - a 66mm long cutter with 1/4" shank.

I'm sorry if in my last few posts I've appeared to think I know more than I do about this. I do value your advice as you clearly have a lot more experience than I have. This discussion has made me think more about what went wrong than I would have otherwise. Still I think there was more to it than the tool extension, since had the router not stalled then I think it would have been fine - it was cutting fine before it stalled.
