Good day, not sure this needs a topic, but I'm consolidating my ideas here and hoping someone can correct me, or offer advice if I am missing something please. First saw here, and I'll be working with a Water (wet) 7" Tile saw (PCE980), and using the MK-225 HotDog blade. I am assuming proper blade care would be: a) Always remove all water, wipe down submerged water basin after each job b) Remove blade, dry blade completely, spray both sides with WD-40 to protect against rust c) Once in a while (not sure exactly how frequently), dress the blade using an actual dressing stick (I'm going with Harbor Freight : www.harborfreight.com/combination-sharpening-stone-62852.html )Any correction or additional advice is much appreciated. Thank you in advance. |

Thank you in advance. I also use a tile saw. I tend to do "a" and "c." I could probably benefit by doing "b," but I get lazy.  You'll know when you need to dress the blade. The rim will have a glazed appearance (kind of brown) and cutting performance will be diminished. The need to dress will be dictated by the hardness of the material you're cutting and how aggressive you are with the cuts. I also swage my blade. Take note of pages 5 and 6 in this pdf. The technique is described there. Care and Feeding of Rock Saws |

Dave, that is a fantastic PDF you linked! I could swear I have seen some of it here, on this forum too, but couldn't find it all day yesterday when I looked! Thanks for it and the rest of the advice. Nice looking Lavic, bye the way. I hope mine looks like that in 6-8 weeks.  |

It's actually a sticky in this discussion area - right above your thread. The title kind of hides it, however. forum.rocktumblinghobby.com/thread/52499/general-lapidary-info |

If you live in Nevada you probably don't have to dry the blade; its dry and it will dry as soon as you lower the water below the blade level. Yes drain the saw tank but leaving a little water will likewise not be lethal because you live in Nevada.
I use a MK225 blade and never dress it even though its cut hundreds if not thousands of slabs, but I am using it on a slab saw and thus feeding it slowly rather than sporadically too fast as its easy to do when hand feeding. A spritz of WD40 is not bad but don't go overboard. Use a rust retardant but don't trust it. Watch your machine and if you see rust, review your procedures.

I don't do any of those things and leave my tile saw outside in the weather. If the blade stops cutting, I clean the diamonds by slicing an old brick.

Thanks all those who chimed in. I realize this topic is not as exciting as pictures of cut slabs of agate, but some day I'll be posting those too. Figured it would be educational for new people too.

Interesting. Yesterday I found someone citing that those "faux" bricks and stones used on accent walls could be used also.

On the topic of WD40 and rust:
To prove a point to my employer I cut a piece of steel in half, glass bead blasted both halves, sprayed one half with WD 40, then left it out in the elements but not direct rain. The sprayed piece rusted first. After that the boss spent a few bucks more for a real rust inhibitor.

While WD40 works okay for a lot of things, there are not too many uses where there is not a better option. My tile saw does not get the TLC some people may give them. Only real care I give is to hose the submersible pump down to try to get rid of some grit. A quick hose down and dump of the tray is good enough, onto the next job. Never had any rust issues. Of course if I had a real trim/slab saw that would be a different story. Al |

Most of the ingredients in WD-40 evaporate very quickly. So any effect it has is short-lived...including its intended use for water displacement.
