1- Put each grit in a separate container.
2- Work through each grit in a different direction. (P600, 800, 1000 (or 1200), 1500, 2000, 3000, 5000)
3- Use soap.
4- Use a new piece of paper towel to wipe away residue for each grit.
5- Have a good light source.
6- Use a hard block (ply and cork work well) as a sand paper backer.
7- Sand each grit in a different direction (which makes it very easy to see if the last grit has been totally removed).

When I was in junior high school industrial arts class we made resin poured chess boards. We used the technique of sanding in different directions for each grit. This was back in the early 70’s.
Excellent!- i'm surprised I've not seen this simple method mentioned anywhere else.
This video just came up in my feed as I was sitting down to eat lunch here in the shop. Fantastic tips on rubbing out. I have always used the same P-grade grits as you, but never went to the 3M 3000 and 5000-I'll give that a try prior to buffing. Love the idea of different sanding directions for different grits. Thanks so much Beau for making these Luthier-tip videos. They are so helpful to me. Here's one that I can share with you: I use a separate spray bottle for wet sanding that has distilled water and a dollup of Murphy Oil Soap (perhaps 1/2 teaspoon?). I put just enough soap that the water feels a little slippery rubbed between your fingers. That way, I never forget the soap.
Thanks- its my pleasure :)
Great tip- thanks - i've been meaning to buy another spray bottle !
Thank you for this video.
@@jukejointjack my pleasure
This is wonderful. You have improved my sanding technique just like that. Thank you!
My pleasure :)
Good tip Beau. Also like the separate tubs for each grit.
You bet!
Good tip Beau, You always have great finishes.
Thanks 👍
thank you so much
My pleasure
Thats why I prefer urethane and use it whenever possible because I can get a very flat finish and start sanding around 1500 most of the time. My nitro finishes always come out just like yours and I have to start sanding at 1000 or 600 too.
Nitro be nitro! I use a poly base sealer coat which is nice.
Great, and right on time for me!
Why don't you keep hand sanding on the last two grits/why don't you use the orbital sander for the whole process?
When you use machinery , you can sand through the finish quicker.
Also, I always have got those little pig tail sanding scratches from RO sanding with coarser grits (coarser= P600)
@@BeauHannamGuitars Thanks! I just wet sanded my first guitar, using various sanding blocks. I saw all the pros using machinery for this part - but it was just too nerve racking for me.
It's very encouraging seeing that hand sanding is not only for the losers 🙃 or just for beginners.
As always - it's joy seeing your work. Your videos are always fun and helpful. Thanks for that!
@@BeauHannamGuitars Pigtail scratches have nothing to do with grit size. They mean you are either moving the sander too fast or pressing down too hard. An RO sander is meant to be moved about one inch per second. At that speed, it will not leave pigtails. Try running your finger across a 12 inch rule and take 12 full seconds to get from one end to the other. Is that the speed you move your sander? Pressing down on a sander can slow it down, and that, too, can create pigtails.
@@michaeldresdner5061 great tip...still a little nerve racking worrying about sanding through a finish
Another great video!...How long do your cure your nitro before sanding?
Thanks. I wait as long as possible- MINIMUM 4 weeks, but 6-8 weeks is better. Im not really spraying nitro anymore (ill do a video explaining why) but i still use this sanding technique.
@@BeauHannamGuitars Great! thank you for the response. My cure time is way shorter...(2wks)hahaha. Nitro is all I know, but never too old to try something new!...Will try a longer cure time & look forward to your video. (My friend restores old cars...he waits up to six months for the Lac to cure before final polishing!)
@@LiloUkulele Your car friend is smart- In a perfect world, i'd spray an instrument and wait 6 month too, but i gotta get paid! hahahha
Very helpful! What do you do when you do sand through a small spot?
Do you mean, when i sand through the finish in a small spot???- that sets you back 4 weeks which is how long it takes nitro to cure for buffing.
Given your stated interest in reducing toxicity in the materials you use - have you tried any of the hybrid water-based finishes from Target coatings? I’ve tried many products in a quest to get away from acetone and their hybrid varnish and shellac are both excellent. The varnish even “checks” like nitro if you get it cold!
Hi Peter- I have some water based nitro to try but I’ve not yet. I just started using (trying) urethane finish- I only have to spray 6 coats rather then nitros 12-15 coats (thin varies according to how much you thin it).
I’m yet to buff the urethane but I like it so far and I’ve halved my chemical exposure.
thank you
:)
can you remove only the top laminated layer of spruce top guitar without stripping the actual colours using this method?
It depends on where the colour layer was applied. It the actually wood was tinted, then you can remove almost all of the finish. Usually colour is sprayed close to the wood then clear coats sprayed on top of that .
@@BeauHannamGuitarsthanks for the quick response... yes the colour is sprayed close the wood, then there is a lamination kind of clear coat, i just want to remove that lamination but i am afraid the the colour will be sanded... i have an old ibanez guitar, it is aged for 15 years, i have so many memories with it, i just want to make it sound more bright by removing the lamination...
do you have any suggestions for it?
btw cheers you gained a new follower/subscriber ☺️
@@surajshrestha4418 you could sand it a little bit. The amount just depends on the totally thickness of the clear coat OVER the color. Just be careful.
@@BeauHannamGuitars i will take that in mind
one last question, which grit would be best? i can have extra patience being extra careful..
which grits would you suggest for that?
@@surajshrestha4418 I wet sand 600,800,1000,1200,2000,3000,5000 then buff.
Why does grain matter after clear coats?
I’m talking about using the sand papers scratch patterns in the finish to see if you have removed the previous grits scratches
@BeauHannamGuitars ok so your using it as a reference
@@guitjolin yep, sand in different direction s for each grit and if you can still see the scratches going in a direction you are not sanding in, you know you haven’t removed the previous grits scratches
too hard to watch. If you didn't pause between every word, this video would only be 10 min. long.
I get it. But I like to give a super informative video on any given subject so you will know as much as possible- it makes a boring video, but I don’t care as information is more important to me :)
