Can you imagine wet sanding with varnish? I can, I have done it, 2 stocks week average. I WOULD NEVER EVER DO THIS AGAIN.
Period.
While I have no experience with "huffing" I can only compare it to "huffing" paint fumes though the concentration is somewhat less if its summer and you can have a window open. I have done something in the region of 100-150 1874 Sharps stocks in this manner for C. Sharps alone. I worked over a year at 2 a week. Almost all precarved stocks some filled finish on open grain production guns, a couple of "Gemmers".
I have tried about everything on the market and various mixtures. Then Mad Monk sent me some boiled oil while I was at Shiloh. Took a little experimentation to get it right. But its like night and day to anything else I have ever used.
Adding the Grumbachers simply makes it impervious to water spots. Basically makes it into a soft varnish that is probably 90% (?) linseed oil.
The photos are of the American grown English walnut stock on my 16 bore rifle. It was pretty light colored with some visible figure before oiling, about the color of unstained hickory in the lightest areas.
This stock was final finished in June 07. It has been hand carried at about 80-100 miles hunting, well over a thousand in vehicles I suspect, many rounds, 500?, of shooting etc etc. Low crawling in dirt rocks and grass. Falling on snow covered mountain sides. Hunted with... it has scatches and dings but shows NO WEAR aside from perhaps a slight, virtually unnoticeable dulling in places. Handling actually makes it look BETTER in most cases.
It has had no further work since June 07 and I think I probably have 1-1.5 hours total labor in applying the finish once the wood was ready.
In getting it out and looking I see it could stand another coat for maintenance but it still looks good and I just never noticed.
it is finished seal and top coat anyway, with home cooked linseed oil mixed about 50-50 with Grumbachers Oil Painters Medium III. I think I used a couple of coats of heavy oil for fill this is standard practice. Maple needs far less.
This is why I keep thinking a lot of people over work stock finishing.
Does anyone really think the English spent months putting on a "London" oil finish??
I cannot begin to tell you the frustration of wet sanding American walnut with store bought varnish. The fill pulls out of a few "pits" at some spot and then needs another day or two of wet sanding to complete an otherwise finished stock.
I gave up on Tru-oil for complete finishes the first stock I tried it on. I used to use Linspeed for a "shine coat". I have also used "Homer Formbeys" low gloss tung oil for top coats.
I really need to rust blue the barrel. I just plumb browned it for 07 hunting season intending to have teh breech color hardened and blue the barrel by spring 08....
Like the shoemakers kids....
My personal guns often get left partly finished.
