Скачать или смотреть Leatherworking Hammer Cast

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
2:00 Making the mold with petrobond sand, baby powder as releasing dust
4:33 Inserting the core in place
4:52 Making risers, help to improve casting quality by increasing static pressure in the mold
5:30 Melting brass in my (now improved) forge and using a brand new graphite crucible
6:06 Removing sprues with metal cutting bandsaw
6:20 Sanding with 2x72 belt grinder to remove imperfection and flashing
6:50 Tiny hole in the face
7:00 Filling it with solder
7:25 Sanding smooth. Off camera also hand sanded up to 1200grit
7:42 Polishing with cotton wheel and fine polishing compound
7:57 Handle material, used ikea cutting board, hardwood.
8:12 Hand planing all sides
8:30 Reference lines
8:57 Tiny finger plane. I love it.
9:17 Shaping the handle with bandsaw and rasps
9:34 Cutting slot for wedge
9:43 Burning the wood with propane torch, looks cool and offer a great texture to grip
10:01 Boiled linseed oil (later applied to whole handle)
10:13 Same cutting board wood wedge, left natural for contrast
