Hand sanding or power? Random orbit, belt, drum, disc? Shaping, finishing? Wood, metal, finish?
Hand finishing and some orbital disk
I think what matters is staying within a product line so grit changes are consistant for the ROS stages. Hand sanding I'll grab what I have.
One annoying thing when hand sanding is when the sandpaper tears. I saw the video where Steve Latta backed his sandpaper with tape. I started doing that and the sandpaper lasts quite a bit longer and can be used to sand round places without tearing.
That’s a great idea Steve uses! It’s definitely annoying, particularly on edges.
I always use two sanding mops (from Klingspor) in the finish process for my box and small projects. I have two basic drill presses, one with 220 and the other with 320 before the finish room. Otherwise, I use RO, belt/disk and hand sanding throughout the processs
Just had a look at my paper stash. It includes garnet, aluminum oxide and silicone carbide. For hand sanding I've always liked garnet simply because I grew up with it and have lots. Aluminum oxide I like on my RO and belt sanders, and silicone carbide for wet sanding.
I like garnet for hand sanding too. I like the way it cuts.
Agreed. I should have said that too.
Recently started using Abranet disks on my random orbit machine--much superior to the old 8 hole disks i was using. Last longer, don't load rapidly with paint and have phenomenal dust pick up. Just be sure to use the backer disk they recommend to avoid damaging the hook and loop pad on your sander.
I really like the abranet, Mirka makes really nice stuff. That said for the price I recently tried Maverick Abrasives using a shop talk coupon code and have been pretty happy, very happy with the price.
I do have some pluming empty cloth (it is a roll about 1 in wide) and really like it and it holds up really well, just wish more grits were available.
I have a variety of brands: Mirka-Norton-3M-hardware store brand-Klingspor-Shopsmith-etc. I like to use high grits (600-1500) for some things, so get those at auto shops. But I don't have an educated preference. Just noting that some of the 5" disks are smaller than others, and dont quite cover the sanding pad. My pet peeve is that on hook and loop disks, the grit numbers are often hard to read and I have to write it on the back with a sharpie if I want to re-use.
Find a hardware store, like Ace Hardware, where you can buy single sheets & experiment. And, get yourself a set of card scrapers. They can be found practically everywhere online.
