then it's not because of the experience!
what model ring saw do you have? the old model was worth it's price in scrap metal, but the new models are neat! you can cut with the ring until there is no longer diamonds on it, without any major adjustments. and the adjustments are really easy to do!
we have had some "professionals" working for us that never did learn that you can't load and push the ring saw like a direct hydraulic unit, the RGC S16 for example. thats the reason we always use the softest rings for concrete, they wear more but needs a lot less preasure to stay sharp. in brick walls we use the medium ring.
also cutting with to little water wears out the wheels faster!
do you use a 4,5mm (1,77") wide pre-cut disk to open up a 15cm (6") deep cut first? it really saves money and nerves!
we only use the ring cutter when it is absolutely nesesarry, when the concrete walls are thicker than 15cm (6") we usually mount the wall saw. the cost of using it is a lot cheaper and the amount of time is the same or less if you hit a lot of reinforcement.
but then we use the ring saw to prevent over cuts (in combination with the chain saw), and when it is not possible or nesessary to use the wall saw.
but then again, when thinking back to the -90's, i still remember how MUCH i hated the old ring saw!!!
i had to cut a 60m (196') long horisontal cut in heavily reinforced concrete at a steel factory, i will probably never forget that one...
