Cascamite, now called Extramite or Polymite. I've seen wood rot outdoors and the glue still be there.

I think Resorcinol type glue is still used by boat builders, not sure of the brand names for it.

Thinking about a second-hand Multico PM20 or similar...

Yes they were popular, should do windows ok no problem.

Hi,

Good luck Nick. I've always disliked attachments and have never used a square chisel attachment for a drill press. I've owned and used industrial Wadkin and Sagar square chisel morticers which were big; heavy and very accurate. I would recommend a second-hand stand alone morticer over the attachment any day. At the moment I have a Startrite combination woodworker with five functions one of these being a very useful slot morticer.

I'm with Big Al regarding waterproof glue as seen at the above link. Once mixed this glue needs using because it cannot be saved.

Out of curiosity what oak are you using?

Kind regards, Col.

So far as I can make out the Multico can be easily converted to a slot morticer.

Hi,

One solution would be to modify David's excellent radio back slot cutting jig designed for use with a router. Once such a jig was made then it would be easy to cut mortices (slots); for deep mortices the work would need inverting thereby cutting from both edges but once set up this wouldn't be a major problem and a production line with forward planning would speed the work up.

I have a brand new 2,100W router bought from Screwfix which will be excellent for such work but unlike a dedicated square chisel morticer the router will do so much more making it of more use especially in a home workshop where space and funds tend to be limited?

The link above shows my router and when I bought it the router cost just under £100 being on special offer making it an absolute bargain and for peace of mind it comes with a two year warranty.

A router of this size is not a toy and capable of serious work whether freehand or mounted into a table; Obviously any mortices cut with a router will have rounded ends but this also applies to my much more expensive Startrite slot morticer.

Just a thought but a router can do so much more than simply cut slots.

Kind regards, Col.

You could do it all with a router but it will be a struggle, slots apart there is all the profiling to do if you want decent weather resistance.

Here's a spindle moulder used to make windows:

How about a bit of DIY?

Years ago I built a contraption out of wood for making T&G flooring boards from PSE stock using a small slitting blade mounted on a drill, it did the job but what a hassle, we were skint at the time so that was our only option, I only ever made a couple of house windows, they were done by hand, all the other windows I made were shed windows for the sheds I used to make at our sawmill, they were simple half lap joints, glued and screwed.
