I did a search ,but couldn't find the answer.I know I saw it sometime back,but I am wondering what grit paper everyone uses for grinding veneers?
Thanks for the help
-
Not sure about veneers but I use 50gr. - 60gr. for lams.
-
Most use a pretty coarse grit.
I think mine is 60.
-
60
-
Ok,thanks.I have 40 on right now.Guess I better lighten up a bit and get some 60.
-
I have 40 on mine now.
-
so when you use the 40, Jeff. do those deep longitudinal sanding marks remain visible after the glue up under clear glass

Wayne, generally no, they're not visible. I recall finding a few once in a light colored bow that I ground with 36 grit, but I had to really look hard to find them. 50 grit is probably a little safer as far as that goes and still aggressive enough. I mainly keep 40 and 50 on hand now.
-
cool, thanks Jeff!
-
I can't seem to find anything coarser than 80 for my Rigid.
Any suggestions?
-
Buy the 80 and cut it in half.. :)
-
Jeez, I wish you would just get over that shoulder and get back to normal (whatever that is for you) :biglaugh:
I'm working on a bow for you, Roy. It's an 80" long ASL tri lam with a 1/64" hickory back, 1/16" poplar core and 1/64" ipe belly.
It'll be tough sledding, I know but eventually you should be able to work into it. Maybe in time for sparrow season. :)

Ya sure can sense the love and affection in har... :)

It depends. If you are going to stain your veneers 80 grit. I have used 60 with stained actionboo and the lines show. More color will get in the deep sand lines. No stain 60 will work.
-
I use 80 and have no prob. I don't like to remove alot of material all at once.
-
gonna go to 80 i think!
we love ya Roy- just dont like to tell you tooo often! :rolleyes: :goldtooth:

supergrit has 36 and up

Attaboy Wayne ;)

Super grit looks like the answer. Big site and you have to dig.
Funny they never came up in any of my search's.
-
Mark,thanks for the supergrit heads up.I just placed a order with them.They are cheaper then where I had been getting paper.

I purchase all my sanding products from klingspoor, or super grit. Quality products and fair prices.
I generally sand bamboo and veneer with 60 because I have seen some lines using 40.
It is rare but it happens however I have an oscillating wide belt sander so instead of lines, it will leave a little wave.
Probably has only ever happened in maple and myrtle though.
When staining, I will sand to 120 or I can detect lines...don't stain much other than maple and this shows lines bad.
If sanding glass, I use 80g.
These are not hard set rules, but work for me.
I have no kown delams due to this... infact, I can't even remember the last glue failure. Not that my weeks go without their own sets of issues :)

The main reasons I use the heavier grit are because I got a great Craigslist deal on a bunch of sanding belts and make my own strips for my drum sander with them, and because most of the 'lams' I make are actually for backing strips, backed bow cores, and lams for trilams, and such... things that are hidden, or further scraped and sanded during construction... not things that are forever visible under clear glass. And when I do make a glass bow, visible sanding lines are so rare I don't worry about it.
You guys mentioned staining... I'll have to look through my bows and see if that isn't the reason they became visible. It's been a long time since I stained glass bow lams, about as long since I saw those lines....
