This is what happens if you dont use the CMS correctly  [crying]

I had to take my mate to A&E to day  after he decided to do a climbing cut on the wrong side of the cutter between fence and cutter.  

It ended up pulling his hand into the cutter from one end of the CMS table so fast that he didnt have time to blink.  

It has shattered his knuckle  the picture below doesn't show how bad it actually looked when he did it as there was no blood just bone on show and his skin was all open.

He has two options the hand specialist told him have part of his finger removed or let it heal in a fixed position.  

Happend on my job so I feel kinda bad like little my fault.

If he wasn't on my job he wouldn't of had this accident.

thats horrible jmb.
they can do serious rebuilds todamage like that. my festool dealer did something similar to that and they wraped it in something to keep it from drying out . everything nitted back fairly good. you wouldnt notice.
get him to a specilist straight away.
 
JMB,

I think that I can speak for all of us here, please let him know that we are thinking of him and hoping that his recovery will allow him to continue to help produce some of the projects that you have shown here.

Godspeed!

I did!  I took him derby Hostpital he's being seen to by one of the top uk hand specialists.  He called up his mate who is a face reconstruction specialist  who contacted the hand specialist for him.

For one second we thought of going Stafford Hostpital but then thought he would most likely have his arm removed if he went their being one of the UKs worst Hostpital.  So decided to go derby was bit further away but is a very good Hostpital.

He's still their he has to stay the night apparently.

Yeah they might be able to make it look good but the router cut up all his bone underneath the skin  and chattered his knuckle bone. They took an x-ray.

I recommend him to get back in touch with the hand specialist and get a titanium finger printed and remove his bone to replace it with a new titanium one.

Like this old 83 old woman had done with her jaw.

Brett,

Why was he back cutting like that ?

John

It was a piece off european oak  600mm long  20mm by 30mm    he wanted to take out 15mm from the centre leaving  the ends 30mm wide and the middle 15mm  the ends where only 20mm long.  So looks like a U shape.   

Ill do a sketch up now take 10 seconds
 
Yellow  section is the CMS fence.

Brown is the OAK piece

The red section is the section he was removing

Green arrow is rotation of router cutter

Purple arrow is where his damage hand was holding which is the part which dragged his hand into the cutter and ramming his knuckle into the cutter as he pulled his finger out that was caused more damage down the finger towards his nail because the wood was constantly pulling towards the cutter.

This is how I believe it happened I didn't see it happen but when I came back and cleaned the blood up etc  I checked out his setup and where the wood was which was still on the CMS table.

If he had asked me how I wanted it doing I would of been happy to have the two end pieces glued on after because where it was going it wouldn't of been noticeable and they are so small.    He said he did it cus he wanted rounded corners as it looks nicer and didn't want joints in the wood.   My CMS was already setup so he thought he could just quickly do it and go onto the next job.  Unfortunately it wasn't a quick job.

I suppose he did it like that because the fence isn't long enough to do it the correct way?
 
JMB, Truly sorry about your friend.  A real bummer.  Hope he comes out without too much stiffness. They can do wonders today. 
Don't get down on yourself because it was on your job.  I'm sure he isn't blaming you, for that matter.

I have a router table (WoodRat) that can safely do climb cuts on the wrong side like that.  I keep cursing it for throwing dust all over the shop and that sort of cut is the worst.  But it is atleast safe and i don't have to get my hands even close to the cutter nor my body in line of force direction.

Wayne:

Can you please explain how to safely do a trapped climb cut? I would think it would always want to shoot the work piece out.

Tom, The Rat is a wall mounted frame with Router mounted on the top.  There is a sliding bar with clamping surfaces mounted n the front of the frame.  The sliding bar is controlled by a crank handle on top of the mounting frame. A cable goes from the crank to each end of the sliding frame.  That cable and the clamping to the sliding frame are the secret. The material can be cut on either side of the wood in any direction and it is always under control.  I was quite nervous the first time i tried cutting on the "wrong" side of the wood, but it is really quite safe. I have made mortice & tennon joints (both tennons and mortices with basically one setup.  I go completely around 4s in either direction with one setup.), DT's (thru & blind), fooled around on scraps with making various sized DT's on same joint, sliding DT's with limitations on size of material, rabbets, tennon stock, and some other joints in trial setups. It is great for fluting.  It takes some time to set up and a long learning curve.  I don't use it enough to call myself a craftsman with it, but it can be fun to work with.

The tool is made in GB and you can go to WoodRat.com to see how it is set up.
A somewhat copycat tool is made in USA that is actually a better tool and supposedly does not throw so much dust and chips and there seem to be more options for cutting.  That is Router Boss and can be seen at ChipsFly.com

I would use the Rat a lot more but for the dust and chips cleanup.  I have just looked over the CMS @ ToolNut and it looks very interesting.  I have been spoiled by Festoys with the superb DC and Would love to not have to use the Rat anymore except for maybe making odd or irregular dove tails and for fluting.  It's an interesting machine but i don't think anybody who has gotten used to the clean working with Festoys would be thrilled with using the Rat.

Thanks, Wayne! Now I remember seeing that...

So, you're basically moving the fence with the work piece clamped to the fence?

Brett,

Dont beat yourself up on this one, was this guy a chippy? If so i cant understand why he would do it this way. Hope the guy is ok but , this is his own fault.

Yeah he is a chippy a better chippy than me in a lot of ways.   I my self would not of attempted what he did on my CMS and im not sure why he did.   I think maybe cus he thought he was only taking 2 mm or so off it would be fine.  I think he had taken a large section out before he did it and just wanted to clean the cut up and just thought moving the fence back and sending it through job done.  

I know its not my fault BUT still doesn't make me feel like im not partly responsible.  

Another picture  bandaged the entire hand and arm for just a finger?!?!?!?!?!?!?!?! lol

That's sort of the case, Tom.  The fence is actually keyed in to the base (table) in a great big T-slot.  The material is clamped to the fence.  The cable that moves the whole thing is completely encased inside the "table".  There are ways to use stops in various ways, but a pencil is the main way to limit cuts and do them all exactly duplicated. 

I'm not trying to advertise the Rat here.  I think it would be best for any further questions about it be put onto a different thread or direct mail.  I have looked over the CMS and for a lot of applications, i think it would suit my needs much better.  Not everything, but for most.  I have not watched it in use yet, but I am expecting the biggest advantage will be in DC.  The other big plus would be the ability to swap toys for different operations (Black market???  ::))
