Peter: enjoy the form. I am ready to finish a fireplace mantle. It is old growth heart pine from a beam out of an old barn. Two sides are weathered and 2 sides are planed and sanded for a clear finish. This will be placed above a wood burning fireplace. What do you recommend for a finish? My main concern is what to apply to weathered sides, if anything; one is the bottom and the other is the 5″ edge facing out. The top and back edges are the planed/sanded sides. Thanks for your help.

root,
I don't think the weathered surface really needs a finish. If it were mine I would make those new surfaces match the old one.
To see what the difference in color will be between the old and the new surface wipe the planed surface with alcohol. You can also use naptha or mineral spirits but the alcohol will evaporate a lot quicker with less odor.
As far as a finish goes; if you used a wiping varnish such as watco , minwax antique oil etc. it will have a darkening effect on the new surfaces. If that is what you're looking for it's quite simple to do. If you use an oil, be sure and lay those oily rags flat outside to dry before throwing them away.
Or you could use shellac. Applying a shellac like SealCoat will minimize the darkening. You wouldn't need much either; two or three applications on the new surfaces would suffice. You could then rub it back with a maroon scotch pad for a dull look or a grey pad and a little wax for a soft shine.
Whatever you chose, less is definately more in this instance. You really don't need to build a significant finish on the mantle. If it was a formal mahogany mantle that would be a different story.
Make some samples with your cutoffs. This will tell you all you need to know visually.
Good luck.
Peter
Thank you, Peter. This is pretty much what I was thinking, but it is nice to have an expert opinion to back-up my thought process. Have a great day!
