Hi there. I had asked a question in a thread I started, and some of our lovely members suggested I post here. I have a new to me Pfaff 130 with some serious crazing (I word I just learned) on the bed. I've read this thread carefully, and am wondering if the French polishing technique will work for me. there is a "bald spot" in one area, and some of the flakes feel kind of loose. Here's a picture. May or may not be as bad as I fear.
Thanks!

You can help this machine with french polish. You will need denatured alcohol and linseed oil. Use the technique as described only start with alcohol and oil (stay away from the decals). Dip cloth on finger in alcohol and then add a drop or two of oil. Now lightly go over the crazing in a circular motion smoothing out the crazy. This will take some time and may take longer than a day or two. After the finish is to your liking you can proceed with the shellac french polish to shin it up. I recommend you practice on an old machine first. Remember to move fast or your cloth will stick to the surface. You can also sand with fine wet or dry sand paper and sewing machine oil to smooth but don't cut thru the black finsih. Then french polish with shellac several times until the finish is even and shiny. Please read the instructions carefully and practice on an old machine before working on your good machine.

I inherited my great grandmother's Davis sewing machine. It isn't valuable, but it means a lot to me. It goes without saying that this machine was put to good use for many years. I remember my grandmother using it in my lifetime when she had something difficult to sew like leather. The machine needs some TLC. The cabinet is in fairly reasonable shape, and I have a lot if not all of the attachments, but some are rusted. However, the decals on the machine are completely black. If you stand at the right angle, you can see where they were and tell their shapes, and you can read the word "Davis." However, I don't know if they are just tarnished and dirty or totally missing. any ideas? Thanks in advance.

I have done something like this on vintage machines before it brings out the old glory of the machine. You must be patient when doing this. Rushing things especially drying times can make a good thing go terribly wrong. Also be sure you have good ventilation. Thanks Glen for these great tips.

I can not for the life of me find denatured alcohol, are any of the other sort of similar products useable for this? I can get methyl hydrate which says it is often used to thin shellac but I don't want to start messing around with something I don't understand. Also I've read that fondue fuel is typically denatured alcohol but with a bit of colour added, any idea if that would effect the process? Thanks
