I am building a mudbrick house with post/beam frame. The windows use load bearing mullions at the sides which are in place already, now I need to fit sills. I want to cut a housing ( or is it a trench?) in the mullion and slot the sill into it so that the cut edges of the sill aren't seen.
I would appreciate some guidance in how best to cut the housings. I could use a circular saw and do multiple cuts, or I could use a router. As the mullions are already in place, I will have to hold the saw or router against the vertical face of the mullion and cut the housing horizontally across the mullion. As the mud walls are almost to sill height, whatever machine I use, I need to cut to within about 60mm of the top of the existing mud wall, so the cutting edge of the router or saw needs to be close to the guide. On my Hitachi 7" saw the blade is quite close to the edge of the base plate so that is OK, but I would have to hold the saw with the motor upwards which I think would be rather awkward. I am leaning towards getting a new router, as my current one is an ancient fixed base one permanently mounted into a router table. I was leaning towards one of the tiny ones, like the 850w Ozito or the equivalent Arlec, as they look like they would be easier to handle in such an awkward position than one of the larger, heavier, more powerful units. As the timber is cypress macrocarpa which is very prone to tearing and chipping when machined, I would have to take several light passes anyway, so the small motor shouldn't be such a problem. That's my logic anyway.
I'd appreciate any feedback or suggestions.
