Conduit and box channeling in QCON

[claynlr]

Hey Guys-

 

Looking for advice on the channeling of conduit and electrical boxes in QCON. Anything better to use than the grinder and chipping method? The boxes are done the same way, as in cut the box outline and chip out? Eyecatcher had a neat looking hand tool for raking out the channel smooth after it was chipped out.

I use a grinder with a masonry cutting disc to cut the edges and a rotary hammer with a broad bit to chase out the channel.

The grinder makes a shed load of dust. But at least the rotary hammer is easier on the wrists than a bolster and mallet.

I know there are specialist wall box cutters available in the UK ( like below ) but doubt they are available here.

Rotary Hammers  are available for about 3K baht - I bought a Hyundai from HomePro.. Good bit of kit.

With a broad bit it eats thru Qcon and other lightweight  blocks. Used it so many times since I bought it. Worth the price and no bruised knuckles.

I used the grinder, chisel and hammer, but next time I'd use the specialist bits if I can get them. Lots of dust.

Don't bother with an angle grinder for the channel, use one of these.

 

it it is designed for the job

Thanks STWW. That's the same tool Eyecatcher had. I will look in Global for it.

You hold the bottom handle with your left hand and the triangular handle with your right and run the cutting edge (bottom left in the pic) down the wall where you want to cut the channel.

 

If you have to do a lot of  channels it's quite slow and hard work using this tool. I found it a lot easier and quicker to first cut five grooves with an angle grinder, and then subsequently use the tool in the picture to clear out the debris.

Hold it with your dominant hand on the big loop and pull it down or across the AAC blocks, it's use is rather like a draw knife. The AAC blocks are quite soft.

Does it do a better job than cutting many groves with a grinder then knocking them out?
Probably lot less dust but.
