Topic tags/keywords: sander sanding

Howdy,

I used to watch DIY shows all the time. Nowadays I watch occasionally. I still learn and get new ideas but I don’t immerse myself.

There is something I have never seen on one of those shows. They don’t show the correct handling of an ROS.

What I see time and time again is people using the sanders with rapid back and forth movements. Wow, that looks like a lot of work! I’ve even seen some of them straining!

We all eventually learn that the rapid movement causes spiral marks. We also learn that applying all that pressure bogs down the sander, messes up the sanding pad and create pits full of spirals.

I would love to see them showing us how to move slowly across the wood. My personal prederence is 2 seconds per inch. I’d like to see them overlapping the sanding by at least an inch. I would like to see them just relaxing as the sander does the job for them.

I’f like for them to show us how to sand a tough spot like a knot with glue holding it together. They can start by showing us we never turn the sander on edge. They can show us to circle the tough spot slowly with the outer rim of the sander. That way the tough spot gets the concentration and surrounding wood is consistently sanded to prevent visible depressions.

I believe that if you do a very careful job with 80 grit, the rest is just a relaxed pass where the work turns to a smooth, beautiful, ready to finish, pleasure.

One more belief. Showing us how to do something the wrong way, can make us believe we suck at woodworking, have no talent, etc. I’m very hesitant to discuss the “right way” because I am a student. I try to solve hard problems on my own. It rarely means my solution is optimal. It does mean I will probably understand some good advice a little better.

Back to the original point, shouldn’t these DIY shows be slightly more responsible? Wouldn’t the tool makers want to give a demo to the shows using their products? I’ve actually read posts where people on this forum swear off effective products because the best teacher they had was the television.

Please comment about how to spread the right advice. If you have any comments about my ROS suggestions, please help improve all of us.

-- Thanks for all the lessons!

Mark,

I agree that everyone expects a TV show to show the viewer the correct way to use a tool. hat said, somewhat recently I did find a YouTube video where Joann Liebler demonstrated the correct way to use a ROS. I can’t find the video at the moment but she’s currently associated with one of the woodworking magazines I believe.

Hi Mark…

Charles Neil has shown sanding very nicely… Don’t remember which one of his many videos that cover it… Just go to YouTube search for him… and start watching… You will learn more as you’re watching them too…

Mark, when you started out, I expected to see a short video on how to do it… Possible to do… would be better than just Reading how it’s done.. :) ??

Thank you…

Hi Mark. Thanks for the post. I’d like to add that I found out there are dual mode orbital sanders out there but not sold everywhere. I have a friend ( Tim the Toolman- not Tim Allen) and he let me borrow his Festool dual mode orbital sander to take down an edge board that I was having problem with using my finishing sander. It worked so well that I bought a Bosch # 1250 DEVS Dual Mode orbital sander on E bay and I love it. It will take 1/16” off a surface so fast in the aggressive mode w/ an 80 grit Abranet disk. But you have to take the slow passes with 100 and 150 grits to remove all the swirls.
You don’t have to bear down with the sander. Let the orbital motion do the work. If you find that you have having to push down hard to take anything off with an orbital sander, the paper is most likely worn and dull!
Good topic for Lumberjocks!!

Cheers, Jim

I hold it by the thick part of the cord where it meets the body and go slow. The sander seems to spin onto or dwell on high spots. I don’t get much vibration either. About 25% is used holding the sander itself. The rest is sort of guiding it in the direction I want it to go.

Howdy, you’ve been there and done that I see.

Dave,
The video is perfect. Someone like her had to correct me as well. All it takes is for someone to show us the right way once. Our finishing immediately goes up 5 notches.

Joe,
You already knew how to do it. There’s no doubting that you would. I could make a video. I just thought you already had one.

Jim and Rob,
Thanks for the additions. This post has over 200 views. I wonder if 5 of them got the message? That would be way cool.

-- Thanks for all the lessons!

I would love to see them showing us how to move slowly across the wood. My personal prederence is 2 seconds per inch.

Proper technique, but would make for boring viewing, esp. for the short attention span crowd.

Sure, but that would look even faster, I think. Show the start with explanation then the completion.

Not gonna lie, I go way too fast and have seen the curly q’s before, going to need to slow it down.

Howdy Joe, I wish you the best of luck. I think you’ll be surprised how much faster you get the sanding done by slowing it down.
