Hi gryphon,
walnut oil, mac'oil, olive oil, time for lunch!

I'm aware of walnut oil for wood finishing but have not tried it yet but the amber varnish I have is made with walnut oil and I have mixed that with linseed to rub on some of my offcuts. I am going to post about it soon. I just don't have the energy to make the post any quicker.

I trust juglans opinions and reports about it. That's what I mean by my previous comment that he knows more and has more experience with these finish's than me. I still have plenty to learn about linseed finishing and I don't know when or if I will be able to make stocks again so I have plenty of time to try other finish's.

Regards,
gabe
