All - I have a few specific questions on 2 projects: 1 is a USGI and 1 is a Dupage purchased unfinished. I have read, and re-read I think each post on the above subject by "M1Army" and "Doug Carlson", corresponded some with them. However, since these questions below may be of interest to others I make this thread.
Both stocks clean, finish-free before I did anything else.
USGI Stock - The USGI "steam ironed" numerous times to raise as many bumps and dings as possible. I lost patience with steaming each dent individually, and whether best practice or not, I just steamed the entire stock several times. I was pleased with the results.
After it dried I sanded to 320, and then I wet sanded it 3-4 times at 320 with Teak Oil, allowing it to stay on the stock for over night (first application), and the 2-4 applications for a couple of hours, before I wiped it off with clean, lint free rag thoroughly. Grain was filled. Then I wet sanded with Teak Oil at 400 (2-3 applications), 600 (2-3 applications), and 800 (3 applications). Based on my readings on the forum, I intend to apply a mixture of Stew Mac alcohol based dyes next, and then wet sanding 2-3 times at 1000, etc., etc. up to 2000 or 2500.
Dupage Stock - Sanded to 400, then TransTint alcohol based dye (ebony) applied, then PTO (15+) hand rubbed in applications. Stock felt great but was an ugly, muddy mess to look at: blackish, but not a "pretty" ebony, etc. I abandoned it for a couple of years even. I came back to it and wet-sanded with Teak Oil starting at 320 (3 -4 times), then progressively finer grit (3-4 times each), and next will be 1000 grit to wet sand . . . up to 2000 - 2500.
To my very pleasant surprise, the teak oil drew out a lot of the black-dyed mess, revealing soft browns from the walnut underneath. It has started to look really nice! (at least so much better than it did before).
To my questions:
M1Army - assuming you are doing a presentation type finish since you are filling the grain of the stock, I have outlined answers to your question below in Red (based on a lot of experience).
Question 1: When wet sanding (after grain is filled), how much time needs to elapse before wiping off the excess? Minutes? Hours? Until it "feels" cured? (They feel "cured" within a few hours. I've usually waited 24 hours for the next application, but sometimes only 10-12 hours). I wipe off the excess teak oil immediately. You just want to wipe it lightly so you have consistent coverage over the stock. I recommend letting it dry for 24 hours before you start your next progression. Also, in this process you should apply a thin coat of Teak oil to the entire stock before you begin wet sanding. Don't just dip your sand paper in the teak oil and start wet sanding on the dry stock.
Question 2: When wet sanding at the progressive grits, how much sanding should be done, how much pressure, how vigorous, etc.? Is it just enough to smooth any imperfections in the last "layer" / "application of Teak Oil? Think of the progressive wet sanding as a very, very light sanding. You need to learn to have a very soft touch. When going from 800 to 1000 the grit is so fine you can learn to feel just a slight drag when you start wet sanding and the paper will slide smooth when you are done [but is a very soft process]. You are really not sanding at this point you are gently moving the paper around. The sanding for imperfections should have been done during your dry sanding at 150, 220 and 320 [I refer to this as the tactical sanding phase] - everything after that is not really hard sanding or removing wood.
Question 3: When I apply the Stew Mac dye, I presume I want to start light and increase it isn't quite what I want? Or, since the Teak Oil is going to remove some of the dye, should I apply a little heavier? Or? I do not stain the stocks at all until I have finished wet sanding at 1000 grit. If you add the stain early you loose too much color as you work up the wet sanding progression. The beauty of alcohol based stain as you can add it late in the process [e.g. at 1000 grit] then you will retain most of the color up to 2000 if you do your wet sanding with a light hand.
If you need more color add it after 1500 etc.
Thank you for your consideration in reviewing the above and contributing what insight you may have.
