100mm through mortises, machine options?

[vibraphone]

Hi

I regularly have to through mortise 105mm softwood planks which I currently do with my side mortiser. The problem is it only goes to 75mm so I need to flip the workpiece and go from the other side to finish. When I have 150 of them to do it eats up the time and I'm looking to speed things up.
I'm looking at the possibility of a hollow chisel mortiser but I'm not overly familiar with them and am not sure on the availability of 100mm+ chisels. I would appreciate any advice as this is a repeat job and I'm starting to go round the bend. Thanks

Although I have never used one and have little knowledge of one it sounds like a job for a chain morticer, have you investigated that option?

Vibrating head chisel morticer, like the Wadkin DM/V.

By side morticer, I guess you mean a slot morticer, face side down.
That's exactly how you're supposed to use a morticer, set Just over half depth and turned end over end to ensure the same side is kept to the fence.
Same for any morticer, plunge, chisel or chain.
For starters the chisel would easily get trapped, badly over heated generated by the continuous amount of waste chips etc and the break out at the outer chisel/chain exit which would be the outer edge of a door stile for instance, if the usual face and edge markings are used whilst machining.
Chain morticer's are usually used for wet and hard wood prefered by the green oakframers also gate, hurdle,
and so forth.
I suggest you check the chisel's for set up and sharpness and you can speed up by buying better quality bits and remember not to knock the crap out of you're machines, 150 stiles to mortice? I would have Trolley loads, around 2 days of solid morticing in the door factory,
Then I would be on a haunching machine for about the same time and then a wedge making machine, Up to 6" wide,
planed to the right thickness, in on the left, in on the right, pull back, touch foot switch, wedges cut, they drop in a very large box, Hour after hour, I am very familiar with work stress, but that's when accidents happen!

Thanks for the replies, especially the input regarding hollow chisel Rodders. Your right I'm talking about a slot mortiser, I have a horizontal machine, very nice but time consuming and doesn't cut square. I think I'm gonna grab an alternax as it fits the bill and will see plenty of use generally. Thanks again for all the feedback
