What disc cutters are we all using then?

[Cal919]

a rail saw would get you most of the way through, you’d just need to clean corners up/get at it from both sides. Id get a concrete cutter in that has all the gear then on the next one if you want to do it yourself you know what to get. Can also chat to their guys to see what they have/recommend for certain situations.

I used 1 in a school years ago very messey had wet vacuum as we were cutting.
You'll have to make good the Reveals as you'll struggle to keep it square etc.
Last rail saw I had a quote for in civic centre about 8 years ago I think was 6500 ish we ended up stitch drilling it

Thats mega money for a rail saw cut. We do have a decent relationship with out concrete cutter but 6500 seems alot if it was a small enough job you could go to stitch drilling instead. I think from memory those cuts i posted before plus them breaking out with a brokk after was around 2k

Mate has one of the Stihl concrete chainsaws, he reckons it's a good bit of kit when it's working but keeps having chain issues, repair place seems to be making a fortune off him in chains and repairs, might be user error though

Been handy over the years not used it for 5 years or more as we’ve been on trust work haven’t needed it

The petrol one is 50:1 not 25:1 like most so it’s a bit fuely and not fun in confined spaces

Hydraulic or electric be better, need 1-2 bar water pressure to lubricate chains, chains and bars wear quick and stretch

I worked on 1 bar and chain a big doorway so like 500 in bits

What on earth have you done to all your nice photo skills Giles?
The last few posts look like crappy screenshots from a Smartphone

That remind me that I've got a rail saw that needs some fettling before I start playing with it

That’s in brick as well, concrete and rebar wears them quicker as well

Used to be £500 a day for the concrete cutting guy he had everything in his van and would do clean cuts cut and break saw, ring saw, etc

The big rail saws are the mutts though I looked into buying a second hand one when we were doing lots of knock throughs was a hilt one for about 6k 600mm blade max and 3m rail with controller, pump etc

But then the knock throughs we started doing between steels so we’re easier just needle them knock brick out then weld a steel in must have done 10 with factory changes

Getting someone out to do the bit no one wants to do sounds like the ideal solution

I was looking at ringsaws too, look ace but won't cut as deep as a chainsaw.

Husky are the main brand for these it seems, I saw the Katsu but no idea on the quality? There's even some electric versions available on Amazon

They can cut about 300 deep, husqvarna is about 3k

I put an enquiry in with EC Hopkins who seem to specialise in these saws, their rep called me back, very helpful guy. One of the things he said is there's a technique to using them to reduce chain wear, they even offer training.

He sent me a quote, 2700 quid for the hydraulic saw then power pack, chains and bars are all extra.

I spoke to the builders again, they told me they had had an expensive quote back but it was 2k for 2 openings... I think that's fine given the wall thickness, they don't even have 3 phase on site so have to bring in a genny etc.

Certainly not worth me getting involved for that amount of money

We had some pre weakening work done on some tower blocks last year. They used these ring saws to cut panels out of 150mm thick walls.

I didn’t watch closely but they were getting several panels 1300 wide and 1600 high out each day.

I think the guy said the saws were about £3k each. No idea on blade life or cost.

Kinda want that hilti wall saw lol but you’d need all the rails and blades and covers etc and 3 phase genny.

The big floor saws look ace

When we were in the brake factory I spent so long cutting concrete floors with poor quality 300mm floor saw with tiny water tank with belt slipping, didn’t know any different then another firm who machine installers brought in hired in giant 3 phase husky saw cutters with 1200mm blades lol I
Was like that’s the way to do it. I bought a bigger 450mm floor saw the clipper 456 is it got a decent tank and good depth setting etc

I think the blades and covers are listed as separate lots.

I think the blades and covers are listed as separate lots.

They are and rails don’t have brackets in that listing etc hard to get it all if you bought the main saw

 

[groundworker]

Just picked this up for £150 as a non runner

Put some fresh fuel in it and blew the filter out and it started straight away

Fella I know has all that kinda stuff, he’s named his big floor saw ‘greta’ as it destroys the ozone when running, it’s that big and dirty! Does retrofit lift shaft pits etc
