Реставрация молотка для выделки кожи
Creating a copy of an old leatherworking hammer in brass. This is a very common shape of hammer for leatherworker and shoemaker, I’ve always thought it looks super cool!
The 3d model is designed in Fusion360 starting from two reference pictures I took myself from the original hammer. It was then 3d printed in green PETG on my CR-10 at 0.1mm layer height,
unfortunately I forgot to add rafts in my model so then to make it release from the mold I had to add those by hand with wood filler and wile I was at it I also primed the whole pattern with filler primer and sanded smooth.
The sand I’m using is petrobond, the core is made of the same sand aswell, it’s sticky enough for a simple shaped core like this one.
Index of operation and materials:
1:34 Making the core in petrobond sand
