HI John

You did a great repair job on the leg

, here's one more way to repair that type of rip out . but I do like to use the dovetail bit it holds better...when you slip in the dovetail spline in place ..

Thanks

John, if it's oak you could try fuming it with ammonia. It gives a slight greenish tinge to the wood without raising the grain (so no rubbing down). Then a clear coat over the top. Try it on a piece of scrap to see the result. Make a tent out of plastic sheet on a frame, put a bowl full of domestic ammonia in with the piece and monitor it for colour change.

That is a neat way to repair chip out from my router. When using oak, even with the slower router speed and a slow feed I get chip out at times. That will make my repairs easier, I know I will get them.

Thanks

Geordie

I like the idea of fuming, it falls under "simple" and the clear spray I have. I seen some posts once about fuming and never really paid any attention to them. This would be something new and worth a shot. I will test and if it looks ok, i'm game. I have mahogony and butternut pieces will this affect them?

Harry/Mike
My second choice would be the Danish oil. I have some tung oil I purchased about a year ago not opened, what would this do?

Thanks everyone, Between the new build and the finish job, I have my hands full. I want to put this piece to bed and move on. I will post the finished look, I am even excited, to see something different.

Once again I thank you for your replies. Maybe this finishing will be painless,,,not.

Thanks
John

I know it is crazy, but the son and I work like this. We leave our options open.

We painted the pieces with primer last night and Scott finished them today. We are going to start the build tonight.

I will post on the other thread
Thanks
John

John. I'm not sure what fuming would do to mahogany or butternut as I've only ever tried it on oak. I think it's something to do with the level of tannins in the wood (?). Maybe Jerry (Mayfield) can shed more light. The thing to do is try it scraps of all the woods to see the results.

Happy Fourth of July, to all members in the USA. Have a great holiday weekend. Independance Day is a proud time, and a time to reflect on the accomplishments of your great country.

John

You may want to move this post but it is 5:15 am and on my way to work.

We are going to find out, I am giving it a shot over the weekend. I will post.
I love a learning experience.

The ammonia used around 1900 was about 50% -very corrosive - the strongest normally available from a chemical supply co. is about 26% still very dangerous. Household ammonia is about 5% and while it works,after a fashion, it takes quite a while(days) and will not get as dark as the stronger solutions. Although I have used chemicals to color wood I can find no advantage,to out weigh the (known) risks and have not used any in many years. Any of these effects can be duplicated with modern finishing techniques much more safely. Give this a lot of thought before you decide to try it.

regards
Jerry

Thanks Jerry,

I will do some research, for sure. Years ago, I was scrubbing a floor and mixed javex and (not knowing) a cleaner with amonia. The gas that came off that was an experience I do not want again. That has to be 30 - 35 year ago.

Now you see why I dislike finishing,

too many options. I was going to go out and buy some house hold amonia,,,, maybe I will read first.

Thanks,
John
