Chet Posted December 31, 2014 Report Share Posted December 31, 2014 I am just curious of what some of you do as far as grit progression when sanding a piece after it has bee run through a surface planer. Also I have used both the Aluminum Oxide and the Garnet sand papers, do any of you have a preference. Pros, Cons? Quote Link to comment Share on other sites More sharing options...
bushwacked Posted December 31, 2014 Report Share Posted December 31, 2014 Curious as well From what I have seen though 80-120-150-180-220-320is a very popular progression. With 220 and 320 optional depending on what you are going for. Quote Link to comment Share on other sites More sharing options...
Boatworks Today Posted December 31, 2014 Report Share Posted December 31, 2014 unless I have a lot of knife marks / chatter to remove I'll typically start with 120 and quit at 180. super smooth surfaces I usually do with the finish and not necessarily the wood (sanding 320-400 between coats and building it up) 2 Quote Link to comment Share on other sites More sharing options...
Doomwolf Posted December 31, 2014 Report Share Posted December 31, 2014 My last couple of projects have been 120-150-220 and they have come out fine. Anything below 120 is reserved for major damage. I also have some 400 and 1500 reserved for wet sanding. Note that this is all done by hand, not sure if power changes anything. I find that 150 is my most commonly used grit, if that helps.

..Kev Posted December 31, 2014 Report Share Posted December 31, 2014 Most of my stuff goes thru the drum sander first but, 80, 120, 180 and I'm done. Couple grits higher on end grain if it's going to show and get a finish. Quote Link to comment Share on other sites More sharing options...

wdwerker Posted December 31, 2014 Report Share Posted December 31, 2014 120 or 150 to start then 180 and maybe 240 then 240 or 320 between finish coats Quote Link to comment Share on other sites More sharing options...
phinds Posted January 1, 2015 Report Share Posted January 1, 2015 80 120 180 220 (or 240) and for a small piece of really hard wood on which I want a glass-like finish I'll add 320 and maybe 400. I may skip the 80 if the surface really looks good and the wood is fairly soft Quote Link to comment Share on other sites More sharing options...
wtnhighlander Posted January 1, 2015 Report Share Posted January 1, 2015 100 - 150 - 220 works pretty well on the domestic species I have been using. Occasionally up to 320 if I need a high polish. A lot depends on the species of wood and your desired end result. I find softer woods benefit from higher grits, especially if you are adding color of any kind. 1 Quote Link to comment Share on other sites More sharing options...
Mzdadoc Posted January 1, 2015 Report Share Posted January 1, 2015 I follow what everyone here has stated and the rule of not skipping grits. I also go 220 or 320 on end grain to keep the finish absorption equal. Quote Link to comment Share on other sites More sharing options...
phinds Posted January 1, 2015 Report Share Posted January 1, 2015 I follow what everyone here has stated and the rule of not skipping grits. But we ARE skipping grits. For example, my 80 120 180 220 skips 100, 150, and 200 Quote Link to comment Share on other sites More sharing options...
rodger. Posted January 1, 2015 Report Share Posted January 1, 2015 150, 180, 220. Sometimes use a smoother instead. Quote Link to comment Share on other sites More sharing options...
TerryMcK Posted January 1, 2015 Report Share Posted January 1, 2015 80 120 180 and maybe 220/240 - life is too short for me to do the intermediate grits. Upto 320 on any exposed endgrain. Sometimes just a finish smoother plane and/or scraping works for me - no sandpaper. Then when finishing 400/600 wet and dry up to 800 1000 and 2000. Remove nibs with a brown paper grocery bag.

Eric. Posted January 1, 2015 Report Share Posted January 1, 2015 Whenever I can hit a surface with the #80 cabinet scraper then a quick round of 180 or 220, that's what I do. Otherwise, just like everyone else...80 or 120 to start, 180, sometimes 220. 320 on the end grain. And hating every second of it. Quote Link to comment Share on other sites More sharing options...
dwacker Posted January 1, 2015 Report Share Posted January 1, 2015 3m show a great microscope video at KBIS showing how skipping grits actually cost you more time and nearly 50% more abrasives. I'm going in two weeks I'll see if I can get it on my phone. There is more to sandpaper than sticking it on and running a sander. Quote Link to comment Share on other sites More sharing options...

Tom Cancelleri Posted January 1, 2015 Report Share Posted January 1, 2015 It depends on what I'm doing. Standard hardwood stuff out of the drum sander I start with the grit that was on the drum (usually 100) then go to 120 with my 5" ROS, switch to my 150/3 with 120, then 150, 220, and that's usually enough. If it's a turning project the sky is the limit. I try to finish up the piece with a light shear scrape on a bowl, and for spindles I use a light pass with my skew chisel. If the surface is even and smooth I'll start with 150 and go to 600. If it's a pen and I'm doing a CA finish I stop at 400 otherwise you get separation from the CA and the wood, then apply CA finish and sand to 12000 micromesh followed by scratch remover compound, then blue ultrafine rouge on a muslin wheel. For friction finishes and waxes I'll go 150-240-320-400-600-Abralon 500-Abralan 1000-2000-3000-4000 Quote Link to comment Share on other sites More sharing options...
