Didn't know this tool even existed!

[bp122]

Never even heard of such a thing. Perhaps another way to skin a cat!

 

[Lefley]

I use one quite often in timber framing in Canada high end houses here in the mountains.and thats a good price!

 

[baldkev]

Never used one but i understand they are a bit vicious

You don't need one.

I can see all the XL 700 Domino's shaking in fear at the sight of such a beast, you would not want to slip with that.

Right you are. I'm man enough to admit I'm not man enough to operate that contraption.

 

[baldkev]

I guess if the clamping setup is good, its probably fine, you just wouldnt wanna put your pinkies near it, or operate it at waist height just in case it caught your trousers

Festool made one but think it's now discontinued, Mafell still do one for about £3,500+

need? what's that got to do with it?

 

[MikeJhn]

Safer than using a regular chainsaw to cut a mortice.

 

[Adam W.]

I have one, I think it's wonderful as it cuts accurate mortices in no time.....Lovely!

 

[bourbon]

used a lot in restoration. you don't want to be cutting a mortise in an oak beam 16'' thick by hand!

I use a Ryobi version:

Also know as the Ryobisaurus by those posh enough to use the red Germanic version.

Is that a chain mortiser? Looks like a drill chisel mortiser with that big handle on the side?

Defo chain, one of the the levers is for clamping the others give you lateral movement, side to side and front to back, better picture showing the chain more clearly, you do need both hands to hold it and switch it on.

or operate it at waist height just in case it caught your trousers

Your quite safe, you stand this side so your not going to get anything caught in it

 

[MikeJhn]

Ah I thought the bellows shown in post 13 was the cutting head, the better picture does make it easier to understand the functioning.

There's a festool that has the chain fixed. It is mounted to a plunge saw gearcase and such, so runs on their rail. I have used one to mill lumber (not large pieces). You have to cut the very tip off the riving knife, but it works well enough. (BTW, I didn't pay for the saw, so couldn't say if it's better value for money than any other milling technique. I really only tried it just to see if it worked.)

This is the device that I have seen a fencing contractor use for mortice in fence posts for the arris rails.

You are describing a beam cutter unless I misunderstand.
