Cutting MDF window board ??

[aveatry]

A table saw would be ideal, but not worth the investment for the times I would use it

For a few years now if I need a tool for a job then I buy it because I have always struggled in the past with using the wrong kit cause its 1 job but then soon enough I have another job I could of used it on - and then another and so regretted not buying it in the first place.

None of the clamps I linked are long enough for that. Find a straight piece of wood and screw or clamp it.
I have thought about this for a straight edge as finding a perfect long straight piece of wood is not easy

Yeah, I thought about that too, as well as using my long spirit level as a straight edge, but with the board only being 24cm wide, needing to cut it to about 22cm wide, and the saw plate being quite wide with the motor housing overhanging, it just wouldn’t work

the best thing to do is cut the window facing side which will not be seen.

I think i under stand the issue - my saw one side the motor overhangs low to the deck but the other side with the plate is too wide to cut 22mm from a 24cm wide board as well as fit a straight edge -- something like that anyway

If the saw is not sat on the piece you are cutting, there is a risk of the saw tilting.
Lower profile clamps may allow the motor to clear the straight edge and clamps.
Another option is to have another piece of material the same thickness next to one you are cutting to act as a support for the deck/plate.

The best option is to man maths a track saw

As mentioned before, the boards come as bull nosed, and I want a straight edge facing.

I like things right, and get frustrated when they aren’t perfect, but I’ve also found that once something is done and you’re not focusing in on the little imperfections, things look good enough in general

That sounds perfect justification for a tracksaw

Yeah, the way I had it set up I was stretching right over my work bench with the circular saw, doing it freehand on a board 1.8m long !! . Not ideal, and I couldn’t do it without changing position. No doubt the pro’s will be cringing, lol

A table saw would be ideal, but not worth the investment for the times I would use it

The next board is 2.3m long…..can’t wait for that one

leave the board full length, then screw a straight edge to the board, putting screws in the bits that will get cut off.

Well….it might not be everyone’s cup of tea, but this is how I like my window sills. No overhang, straight edge, flush with the wall. Looks nice and modern, which is what I was going for

Unfortunately, it doesn’t look as good as I hoped, as the paint I was using is very hard to work with…Rust-Oleum, All Surface Paint, Dark Grey. It’s a pain in the ass to work with, leaves ripples and shows slight imperfections like sanded screw holes . Hopefully, a second coat next week will sort that out

Thanks again for all the advice everyone, much appreciated
