So I’m almost done with this project. I didn’t have a piece wide enough to finish the S but it should be in the mail today.
The inlay is Purpleheart on a cedar background.

I like using tung oil but I’ve read in a few places to not use oil on Purpleheart. As it stands some of that Purpleheart had to be put in the oven to restore the purple color.

So i am asking for suggestions on how to finish this piece. I don’t need a super high gloss, but a little shine would be ok.

I’m also open to suggestions for finishing the edges, routing a border groove, etc.

Thats going to be a gorgeous sign. I've never used purple heart. I've heard it may bleed so, I'd use a water based spray finish. Water based dries pretty fast. Spraying would eliminate any transfer of the color you might get from a wipe on or brush application.
I wouldn't add a border. And, any routered profile would be as to your tastes.

NO,NO,NO,NO,NO....... No water base directly on Purple Heart. I just got through resanding off the water base Poly and putting on shellac. Maybe water base over the sealed purple heart might work, but not directly on it. It will be beautiful with the shellac, I use spraycan shellac Zinnser,and give it at least 4 coats lightly hand sanding in between with 400g.

Purple heart will turn a very dark almost black purple over time. Sunlight will also bring out the purple when it is newly finished.

Is it going outdoors, Mickey? I may be mistaken but I was under the impression that Purple Heart doesn't like UV.
If it is going outside then you may need to include UV filtering in the finish(?). I hope I'm mistaken 'cause that's too pretty a sign to be ruined by sunlight.

Gene the Problem I had with water based MinWax Acrylic was it turned the purple heart the most awful greenish black, like swamp mud color right away. I have not had any experience with bleeding into adjacent colors, Paduk is the one that really bled for me.

I will be using UV blocking in whatever i use.

Interesting, Herb. From my reading, it seems that most people recommend waterbased finishes, with UV inhibit.

Also, i appreciate the compliments. I am very new to doing inlays. This in the fourth attempt I’ve made at doing an inlay. Pics of the first three are in the Guide Bushing and Template forum.... as making the template, or stencil, is the real art to doing this. That’s what takes the most time and has no room for error. Each letter took two to three hours just to make the stencil. But i now have it and it’s reusable! Hopefully I’ll eventually have the whole alphabet and will offer them as printouts to you guys. Just gotta be sure it prints correctly. Ive learned a lot from you all.

Thanks for the correction of my suggestion, Herb. It was a guess on my part. Glad you chimed in before disaster struck. I'd really hate to be the reason for screwing up all that work on such a beautiful project.

we can blame you anyways....

So i put some tung oil on a scrap piece. I put it on heavy. Came back an hour later and wiped the excess with a white cloth and there was no bleed.

Since i like tung oil i will likely use it, then come over the top of that with something compatible and that has UV inhibitors.

I’m willing to be talked out of that, however, with some sound reasoning.

I have taken a purple heart unfinished board that was kind of Blah and set it out in the hot sun for a day and it really turned purple. Once it is finish it slowly darkens to where it is almost black.

No help here, Mickey, I just wanted to congratulate you on the nice sign.

 

[DaninVan]

Good to know, Herb! I knew UV was a factor but wasn't clear on which direction the colour change would happen.

 

[Mickeyfolse]

I was able to finish the sign and get one coat of oil applied... i am pleased with how this will look.

Congratulations on a wonderful job. Any chance of a few progress shots? I don't know about outdoors but Iv'e made pens out of Purple heart and finished as shown. The last one though was finished with CA glue for an ultra high shine.

Sure thing! Still looks the same, just shinier! Lol. Next time I'm on my phone instead of iPad I'll post a pic.

I've already started a new inlay project. Won't be too long till it's done. And planning to try to do a small keepsake box next. I've never done a box before.

It came out well, but I've learned a lot from that purple heart sign and will share the lessons soon to hopefully get input and advice.
