Wall chaser

[Kakys2]

I am in the market for a low dust alternative too a disc cutter for chasing out my walls. My last house was about 75% engineering bricks (I think they had been overcooked aswell as you could see grey crystals in them), there was a lot of dust created when I used a disc cutter. I am about to start the rewire on my present property which is black mortar and lath & plaster which is a lot softer but a lot messyer, I have never done a house this old before so any hints/tips would come in very handy.

Afraid there's no such animal!! ....Your going to get clouds of dust with wall chasers as well, maybe not as much, but still enough to coat everything in the area!! lol!!

Lump hammer, bolster, dust sheet and enjoy.

If you find one, let us all know as it would be a first.
Welcome to the site BTW.

do it by hand. on an older house, you may well find that the plaster is thick enough to sink 25mm boxes without going into the brick. if you must use wall chasers, evacuate the house for 3 days and buy some masks.

I thought I'd seen something at a trade show a few years back where the blade vibrated (a bit like what they use to cut the plaster off your arm with) but I could be imagining it. I cant evacuate the house me, the wife and the dog live there.

That sounds like a multi-tool, but would not hold hope in using it on brick as it would cost a fortune in blades.

Sorry for deviating slightly off here but on the subject of multitools.:-

My Bosch (POF) blades will last only a few seconds if they hit hard surfaces like brick. I now re-cut 4 teeth in my worn-out toothless blades with a small triangular needle file held at an angle. Slightly set the teeth by bending in alternate directions with snipe nosed pliers and the jobs a gooden.

I well reprofiled blade cuts wood/plaster far better the a blunted toothed Bosch blade at £7,50 a time.

I just sharpened my chissels.

I've used a twin diamond blade chaser with a vacuum attachment before with pretty good success. Its never going to stop all the dust but will make a significant difference.Make sure you keep the vacuum duct clear of debris or the dust is pure hell

and you think its all going to be a lot "softer" and easier going because its black lime?...Think again because you will see/feel how tough them old bricks can be once you start sinking boxes.....and forget about an EBS mate....wont touch em wont that..lol....best advice i could give you for a lowdust chase is the tried and trusted mate.....good hammer with some effort behind it ...and a good bolster n all.....dont be scared of a bit of manual work mate.....a machine aint always the answer.......

Got a wall chaser with vac attachment and its crap. Dust is inevitable when chasing/sinking boxes.

diamond cutting edges perform better on hard materials.......its the softer-more abrasive stuff (asphalt) etc that does for diamond blades ......

I have looked at box sinkers and have always wondered if they worked and I have come close to buying one a couple of times but I have stopped myself as I just couldn't beleive they were ant good.

ive used a box sinker before and theyre quite effective on the hard stuff, worth it if youve got alot to do.

not worth using on softer block/thermalite as they tend to just destroy it!
