Looking at getting some small parts machined using Brass.

I doubt the accuracy is that important. I think these are just weights you put in an RC car to compensate for the low mass of LiPo batteries. Brass is not much more dense than steel, so you could use steel...perhaps stainless. That does loose the eye candy which is the main selling feature on most model car parts.
I've not used them - I prefer to just fill every available space with batteries for more power :naughty:

I could remove the rounded edges off the parts no problem, they are purely aesthetic. What I've done with those parts is simply take the original plastic part and replicate it, the design could be simplified no problem.

The reason for brass is as Jonathan highlights, the eye candy factor... Steel weights are starting to pop up but they simply lack any style or bling factor.

I will revise the designs tonight for simplicity, if anyone would like the files please let me know. Maybe someone with a bit of brass knocking about could machine one for me to try? Paid of course.

The other option to save money on materials is to sand cast them. Then machine or just buff them ... You can cast with scrap brass, like plumbing fittings.

Nothing hard or compicated to making these.
Nobody really has brass just knocking around given the price.!!. . but as it happens I do have some brass knocking about and if the right dimensions I'll have crack at doing them for you.
Thou Warn you now brass aint cheap so don't expect the parts to be cheap by the time you have added machine time.?

Can't give any price untill full dimensions are known and machine times worked out.!

Jazz, I can send you the .ipt's to take a look at. PM me a contact email and I'll send them straight away. As mentioned in first post I simply need a prototype of each part to check fitment and from there it'll be onto quantities of 10-15pcs minimum, that number could easily be higher but all depends on the interest I receive from potential buyers of the parts.
