what is up guys, in this video i will be showing how you can restore an old rusty handsaw with a bit of sanding, polishing and replacing an old broken handle with a 3d printed one. ok, so lets get started. as you can see my saw was in pretty bad condition due to a long term exposure in a very humid areas furthermore, the handle was broken so we need to replace that with a 3d printed one. i firstly remove 3 screws, that were holding the handle in place and after that i measure it and started modeling a new one in a solidworks.
old woodworking hand tools for sale, a great trick when modeling a copy of any part is to take a picture of most detailed surface and trace the edges of a model in the picture so we can extrude it to a needed height. i also applied a few chamfers and made 3 holes for the screws. moreover, a 1 mm groove was cut in the middle of the handle so we can fit in the saw blade. after that i just slice it and print it with my printer.
the estimated print time was around 3 hours so in the mean time lets clean and polish our saw blade. firstly, i tried removing the rust with 200 grid sandpaper that did the job perfectly but there was still an unusual oxide layer on the saw blade, so i tried using a dremel but there were not much difference so the last idea that popped into my mind was to use a vibrating sanding machine. it removed most of the oxide layer, so we can finally polish it for a nicer look. i should have use a sand paper to remove more deep scratches but i was ok even though the finish was not 100% perfect. so when the handle was printed i clean the support material and install the handle back to the saw blade. and there we have it i am really happy with the results, the saw looks pretty aesthetics but the only thing i would change is the thickness of the handle where you hold it. it is a bit too thin for my hand but if you put a hard foam around it it should be ok. thank you for watching, please subscribe, like, share and leave some comments and ideas about new projects , so i would know what you guys think i should do in the near future.
