Thread: How would you cut these perfectly level with each other?

Can you mount the track from a tracksaw or any other straight edge (long level, rigid aluminium extrusion, etc.) and use that to reference a saw, router, or other cutting implement? Otherwise you could snap a chalk line and cut to that. I'd prefer gluing or double side taping a straight edge on the wall, I don't think I would cut particularly straight over 2.5m with something with a small reference surface.

If this is lining a wall, could you not just add a small tri mould (or similar) once the ceiling is in place? This will cover the gap and the saw toothing of the boards.

Thanks.
The problem is getting a tool to the area. I have between 6mm and 35mm of clearance and the only tools I have the will fit are the multi tool and a couple hand saws.... but I could buy something. Circular saw would have been perfect, but it's clearance is 40mm.
I like the idea of creating a fence for a hand saw, but I still think I will stuff it up given the small amounts I need to remove.

Sorry to say, I wouldn't even try to do it.

Mainly because you of the range you specify: if 'twas 7mm overall it could be done, sorta, but trying to remove 1mm... [shudder] That's where I suspect you'll run into problems attempting to keep any form of 'straightness.'

What do you want to accomplish? Lining the ceiling? If so, there are alternative approaches, especially if you're going to apply quad, trim or moulding to the joint.


If I absolutely had to do the job, I'd probably cut a length of scrap to about 7mm(*) by about 25mm and tack that in the corner to the ceiling joists. Then I could press the multi-tool blade up against it and have some assurance that I'm cutting straight & square. It would not be perfect, but probably as good as you'll get.


(*) Actually, it'd be 7mm minus the kerf that the multitool leaves. But If trying to fit something above I'd ignore the kerf to leave myself the wiggle room. If anything, I personally would ADD a cm or so to leave an expansion gap for the wall boards and cover it with trim. But that's assuming you're lining the ceiling.

I can't get the ceiling boards in without cutting, and it would be good if they sit level... I am analy retentive, and I really don't want to add to the stuff ups I've already made

I would attach something straight and hard like Alumimium Extrusion to your boards along the cut line, could be attached with double sided tape if you have no other fixing options, then run your multi tool along it. Scoring the cut line with a knife first might also make for a cleaner edge.

I think the scrap spacer might be a winner...

It's probably not going to help where you only have 6mm of clearance, but the clearance of my tracksaw (TS75) is 12mm. I'd imagine other tracksaws would have similar clearances.

Uuuooowww nice, if only I had more kidneys to sell, when's Ozito making one? I could prbably hack one for even better clearance.

They already do.......... or buy new from Bunnings

You would also lose the width of the blade, so more like 14-15mm. However you forced me to go measure my TS55 and that is 10mm plus 2.2mm of blade. Having owned it for a couple of years I never twigged just how little overhang there actually was.

You can't tell from the photo, but the ruler is to the inside part of the kerf so clearance is 12mm.

Both the spacer and metal fence didn't work well.
The multitool introduces a lot of vibration and the blade (Diablo 65mm) has a lot of flex and will dance around when it hits the fence, so it's easier free handing it.
+ it's overhead and really hard to follow the line, so I stuffed it up... looks sooo bad, at least the trim should over it up.

@KahoyKutter when I went to get the multi tool blade I almost got excited until I could read the description...

Straight edge stuck on with double sided tape, multi tool with a round edge blade, a complete round one would be best, cut half way then finish with a sharp, 5/8” chisel if there’s a plate behind the panelling to stop it splitting. The better way would have been to fit the ceiling first then cut and fit the wall linings up to it but of course you know that now.
