Again finding myself the recipient of bonus free time, I've been able to apply the tung oil finish and do an extra little job.
I'm using 100% pure tung oil. No polymers, no accelerators, nothing. Nothing but a dash of mineral spirit to reduce the consistency a little.
I mixed up in a container and used a foam brush to apply the mix. I love those foam brushes. Don't ask me the mix ratio, it's what I call "dat's a nice consistency".
You can kind of make out the streaky swirly marks of the oil there.
I applied a thin even coat and left that a little while to begin to penetrate before wiping off the surplus oil, and then I did the thing that some people might shout at me for doing.
I grabbed my 18 volt cordless sander and some 800 grit disks. Maybe you shouldn't do this, I don't know, but it works perfectly for me. I do take the precaution, when wet sanding oil, to ensure the punched extraction holes in the disk do not match up with the holes in the sander's platen, to avoid gumming up the insides of the machine.
Obviously you can't machine sand every little detail, but the time saving is significant and I think the results speak for themselves. It's impossible, of course, to convey tactile sensations online but believe me when I say that the resulting surface is dolphin smooth. It's a joy to touch.
This won't be glossy, it will be a sheen. Not a true matte and not a satin, just a subtle sheen, enough to keep the good stuff in and the bad stuff out. Oil is my favorite finish for more reasons than I have time to list.
I did both sides, all the edges and details being done by hand with 1000 grit Norton paper, and left it a while to set up supported minimally on dowel rods.
That will take a few days to fully cure but as long as I'm not left with wet oily hands when handling the body, I'm perfectly happy to carry out minor work on it. It's not like paint. You won't wreck it by handling it.
Minor work such as fitting the string thru body ferrules. As I have already mentioned, I'm not going to use the ferrules supplied by Babicz. They are unneccesarily huge, requiring a 1/2" mounting hole. It's one of my few quibbles with an otherwise outstanding piece of enginerding.
I'll use these instead...
I'm going to use metric sized HSS twist drills, as the 9.5mm in my particular set actually measures out to 9.42mm, which gives me an interference fit.
I worked through several sizes to embiggen my holes. I don't know if embiggen is a word and I am really not sure about applying it to my holes even if it really is a word but I did that, deal with it, move on. I went through 6, 7.5, 8, 8.5, 9, and finally 9.5mm. between each drilling I used a countersink to lightly chamfer the lip of the hole to minimize tearout.
After not really very many minutes I was able to install the ferrules. I'm happy with this result, and other than the stacked tone pot it's one of very few visual indicators that a beast lurks just beneath the beautiful skin.
You absolutely can (and maybe even SHOULD) complete a parts bin build like this in a single weekend, even with a few modifications having been necessary. I'm keeping track of my hours spent and at the end of the project I'll tell you how long it took.
