Painting works are coming to the end. Last days I finally got some lack cans to do the final coating. Not an easy task due to COVID'19 lock down. I sprayed most the prepared parts and this is the result: Overall, the finish quality is really good. The enamel used is of semi-gloss sheen and gives a really silky touch to the surface.

The last owner shouldn’t be very proud of it… After disassembling, the general state observed is good enough for a maybe 50 or 60 years old saw. Most of sliding parts are well fitted.
