Hello. I'm new to the forum, and I know next to nothing about CNC machining.
I have a CAD program (Autodesk 123d) and I'm trying to make a metal yoyo.
Yoyos have changed considerably in the past few years. The wooden toys you guys might remember have changed into high precision, CNC machined (On a lathe), expensive novelty toys that go anywhere from $50 to $250. They are usually made from Aluminum (6061 and 7075) and also Titanium.
The project I have been working on is pretty simple:
1.Use CAD and design a yoyo.
2.Go to a local machinist and have him/her make me a run of about 50-100 yoyos
3.Have them anodized by an anodizer.
4.Sell them to other hobbyists.
Although price varies, I'm aiming for a $100-$150 selling price. I'm most likely going to use 6061 aluminum. Machining tolerances have to be pretty high (0.003mm or maybe a bit less.)
The outer diameter of this yoyo will be anywhere from 50mm to 56mm, which means I'll be using a bar of solid aluminum with a diameter of 2.5 inches to machine this.
The weight will be 64-68grams.
The yoyos are machined one half at a time. Therefore, one yoyo consists of 2 halves, an axle (Usually a grub screw),and a bearing.
This is where the question comes in.
I am aware that lots of factors can change the price, and I need an official quote, but how money would it cost to have it machined? Let's say that I'm going for a run of 100 yoyos, so that's 200 halves. I want it made on a lathe, and not a mill. I don't really care for anodization and other things, but I want just the price for machining+base price for the metal (6061 aluminum). I just want a ballpark estimate of how much that would cost before I go out and bug my local machinist. Tell me what other factors I need to include if needed. Thanks!
