Newbie Question - Getting sawdust off/out of the wood
I had asked this in the long thread I had going but decided to pull it
out of there into this subject specific post. In the other thread, someone had warned me against using tackcloth and had advised me to make my own using old shellac. I responded with: So, if tackcloths are out and I don't want to make my own as you describe, what about wiping off the wood with mineral spirits, thinner, or alcohol? Do these raise the grain and require light resanding after use as water does? I don't like the idea of having to sand again AFTER wiping sawdust off with water -- it seems like an endless cycle -- water -- sand -- water -- sand... |

Mineral spirits does (do?) not raise the grain the way water does. I'll not say it does not raise the grain at all, but not enough to warrant resanding. Alcohol in the shop will always have at least a little water in it, but probably not enough to be a problem either. -- FF |

I have never had a problem with it in the last 25 years. So, if tackcloths are out and I don't want to make my own as you describe, what about wiping off the wood with mineral spirits, thinner, or alcohol? In some cases like when using an open grained wood like Red Oak, the liquid used can actually cause the pores to fill with sanding dust and cause an uneven appearance. Do these raise the grain and require light resanding after use as water does? Petrolium pased products do not raise the grain like water does. I don't like the idea of having to sand again AFTER wiping sawdust off with water -- it seems like an endless cycle -- water -- sand -- water -- sand... I would not either. You are apparently wetting down too many times. Sand through all your grits and then lightly apply water to raise the grain. Then do a final light sanding to remove the fuzz. This most often will be all you will need to do before applying a water based finish. I prefer to use compressed air over anything to remove the dust of the project and out of the pores of the wood. |

Thanks, what I'm getting at is that after I wetted and sanded I've got
a little bit more sawdust in/on the wood. I've got to get rid of that, somehow. BTW, no air compressor here -- wish I did have one. |

And if it's an oil-lubed, do you have an oil filter on it? I've heard that an oil-lubed filter can spray minute quantities of oil which can cause problems with the finish. I just bought a small (read: cheap) oil-lubed myself, and I've been hesitant to do what you describe for fear of what I just described. Am I worrying too much? Thanks. |

CORRECTION:
The above should have been: "I've heard that an oil-lubed *compressor* can spray minute quantities of oil..." Filters almost never do any spraying themselves... |

Converting to waterbased finishes has raised a whole bunch of issues.
I was raised with oil based stuff and was happier than I was when waterbased shtuff first came to California. People have reported contamination from tack cloths, presumed by me to mean WB finishes instead of oil based. My suggestion was based on what I believe to be a Jeff Jewitt suggestion for possible win-win use of expired shellac. Avoid off the shelf tack cloth and avoid dumping expired shellac down the drain. Makers of finishes have made GREAT leaps in their finishes and oil based shtuff is out of my inventory. I don't use waxy shellac as dewaxed is more universal as an undercoat and anything can be used on top. Furthermore this is Thursday.

Try wiping off the dust with your non-slip router mat. Shake the mat
after each wipe. |

Probably more of us use them than make their own. The prevailing theory of those who rail against tack cloth are that they can't crowbar the 99cents out of their wallet to buy one. I am curious about giving a newbie the advice about making one out of old shellac. How much old shellac do you happen to have lying around your place, rbrandywine? |

Uh, well not a lot. ;-)

I don't like the idea of having to sand again AFTER wiping sawdust off with water -- it seems like an endless cycle -- water -- sand -- water -- sand... I generally use mineral spirits if I will use varnish. With oil, nothing is necessary. |
Newbie Question - Getting sawdust off/out of the wood
Are you saying you go water--light sanding--mineral spirits when
applying varnish? That makes sense, if it works. But why wouldn't an oil finish require the same treatment? Is it because the oil flows through any small amount of sawdust *on* the wood and sinks into the wood? |

Leon, Is your compressor an oil-lubed or an airless? And if it's an oil-lubed, do you have an oil filter on it? I've heard that an oil-lubed filter can spray minute quantities of oil which can cause problems with the finish. Oil lubed. I have never had oil come out of the hose. More often I have a problem with moisture condensing inside the hose and spraying on the wood but that is only a slight mist and quickly evaporates. IMHO your finish will probably hide/blend with, any specs of oil if any comes out. I just bought a small (read: cheap) oil-lubed myself, and I've been hesitant to do what you describe for fear of what I just described. Am I worrying too much? Probably, I never have had that problem. |

Oil does not form a film, so any dust just comes off with the oil rag. It is cleaning and applying at the same time. Some people like to sand while the oil is fresh, thinking the dust fills pores; but authorities say it comes out as fast as it goes in. |
Newbie Question - Getting sawdust off/out of the wood
That's great! Either way I go now, varnish or oil, I've got a
reasonable method for cleaning the wood up before finishing. |

That's a very good question somewildmon -- I'll be interested in
hearing the answer. I've heard of sanding sealer and will read up on it here but I'm trying to keep this simple as I've got a LOT of wood to finish. |

Newbie Question - Getting sawdust off/out of the wood
Hello,
I use those pastel dusting cloths with the surface with all the cut fibers. I looked on one but did not see a brand name. They hold an amazing amount of dust can be cleaned over and over. . Especially good for final wiping before finishing. I was using used dryer sheets. I do a lot of spray finishing and they seems to work well, get very smooth surfaces. I also use a compressor which works fairly well but seldom seems to get the last bit of dust. Sometimes I use a vacuum with a soft brush. Don't use tack cloths anymore. Mike R |
Newbie Question - Getting sawdust off/out of the wood
By pastel dusting cloths do you mean something like Swiffer Sweeps? I
think I may try those, too. I'm guessing that if a tackcloth *does* put a little oil on the wood that a quick wipe with mineral spirits would clean it up. |
Newbie Question - Getting sawdust off/out of the wood

I was just having a quick re-read of all the replies here. I'm a
little confused, now, about the use of water -- I thought you *had* to use it to raise the grain at some point in the finishing process. But -- it's almost sounding as if you only need to do that if you are about to apply a water-based finish (which I'm not). Is that correct? With oil-based products do you just use mineral spirits? |

Thanks, I'll try both ways and see what results I get.

Newbie Question - Getting sawdust off/out of the wood
Actually, on 2nd thought, I'll just clean with mineral spirits -- to
keep things simple and save some time at the expense of some money. |
