hello, i am getting into casting because there are specific unique parts i must make, some of these parts need to have threads in them so i can screw them to plastic resin parts. if anyone knows how to do that, or if it can be done, please let me know? i dont know if that is possible in the casting stages or will have to have a machinist put it in or can i do that myself without a metal lathe? i do have a drill press.. thanks.

i used to term hood ornament wrong, but i just wanted to give an idea of what i was talking about. i am building a trike, a bicycle, not a car. and its a one of a kind statuette of a goddess.
the threaded rod thing you mentioned might work just fine. however i am planning on casting lots of parts for this bike some of which will involve brazing to connect them to bigger parts.
this is a cargo bike i will use as my main transportation, i am also casting a head light to attach to my front fender. i will be making the headlight out of LEDs.

For starting out and ease of casting I too would recommend starting with the pewter. Why must you braze it on? You could cast a piece of threaded rod into what you are making and fasten it that way.

terrific, thanks!. i will look into these. would you know off hand if castings from these metals can be chromed and brazed?

Brass or aluminium are relatively easy to do on an open forge with minimum tooling

The pattern part is the most difficult bit

thanks for responding! i was looking at pewter on an ebay. a store seemed to have a nice little melter, the molding stuff, ingots. i asked the store owner if i could braze with pewter, he said no. i want to braze the hood ornament on he said i couldnt braze pewter. so i cant use pewter for this project although i am definitely looking at using it in the future.

For just getting started with no background or assistance I would suggest a no-lead pewter!

hello. I need to cast a hood ornament for a project. it will be about 3-4 inches high, i will like to paint it or get it chromed afterwards. i might even braze it to my project in this cast a bike. i dont have any casting materials yet, but i was thinking of sandcasting, because i cant afford lost wax. my question is what kind of metal can i use? i dont want to fool with anything that has lead in it of course. thanks.
