Am I missing anything? Thanks!

One more project I am considering. Any suggestions would be greatly appreciated. I'm thinking mild, soapy water and a soft toothbrush, and maybe some metal polish for the decal. Any other ideas? What about the case? Thanks![ATTACH=CONFIG]504096[/ATTACH][ATTACH=CONFIG]504097[/ATTACH][ATTACH=CONFIG]504098[/ATTACH][ATTACH=CONFIG]504099[/ATTACH][ATTACH=CONFIG]504100[/ATTACH]

So, after three hours of cleaning with denatured alcohol and linseed oil I'm not sure im making any progress. The machine feels the same but now I have streaks and scratches. Help, please![ATTACH=CONFIG]504111[/ATTACH][ATTACH=CONFIG]504112[/ATTACH][ATTACH=CONFIG]504113[/ATTACH]

I went back and compared pictures this morning. I do think she is looking better! A couple of places are a little cloudy, and one place really shows marks where I worked on it. I went back but can't find the post where it says what to do. Do I keep at it with alcohol and oil or should I move on to oil and shellac? Thank you so much for all your help, miriam!

You can repeat the alcohol and shellac a couple times then you might need to go over it with the linseed oil and denatured alcohol if it doesn't go smooth any more. I'm good at messing it up and getting in a hurry and making it blotchy. Glenn is the king of slow and patient on the finishes.

Shellac flakes are disolved in alcohol to become usable. Most of us skip this step and buy the premixed shellac. I think I saw such a thing in one of your pictures. To spread it evenly - we add a little linseed oil. It helps it glide. Shellac wants to stick.
