Cast Bronze Spearhead From 3d Print and Car Parts

[@RealProjectTube]

What do you guys think? Did it turn out ok?

I cannot tell you how long I've been looking for something like this, thank you for the vid, one thing though do you know how to cast the hole for the shaft without drilling? Thanks 👍

[@RealProjectTube]

@@jimbob9963 To cast the hole without drilling you would place a "core" inside the mold where you want the hole. I've never done it before but if I had known how long it was going to take me to drill that hole I probably would of attempted it.

@@RealProjectTube ok thank you I've watched lots of videos but no one ever shows it

Looks nice. This one definitely would have benefitted from a core. Save a lot of metal and machining that way, and also cut the weight way down... The 3D model of the inside of the socket already exists from what I see here, so the corebox ought to be easy to derive from that if you ever cast another. Hardest part would be supporting the long skinny cantilevered core. There are ways to do it. To the commentor stating nobody has shown how to make cored castings, I assure you that there are several really great metal casting channels that have shown this in great detail. A few search terms that might help here are foundry cores, coreboxes, coreprints, sodium silicate cores, patternmaking.

@@tobhomott 100% should of been a core. I should of spent the time to learn how to do a core at the time, but I didn't and regretted it later when drilling it out. Next time I'll do a core lol.

Great!! A request, can you make the center round instead of square? The original has a round/cone shape all the way up.

[@jeanladoire4141]

The original piece was hollow all trough until the tip, to save weight. Isn't 12% tin a bit much ? what about a 9/10% tin ? It would be much tougher

Anybody remember the 1981 movie Dragonslayer? This really looks like the magical spear from that one.

[@TheSpencomatic]

well done

[@warchildodin]

It's looking good.
