I have had a new lathe for almost two years now and finally made my first project. I melted down beer cans and rough cast a slug which went to the lathe.

It came out pretty good albeit imperfect. Maybe when I get the bike charging again, I can focus on making other parts.



 
looks pretty rough, would be better and easier to machine one from a solid bit of ali bar or buy one from a specialist
 
not bad. you're makin me want a lathe now man. really making me want one.
 
Why not machine a sight glass window in the side of it to verify fluid level?
 
Very cool! Did you cut threads for the top to screw on? Did you put an O-ring or something on the lip to seal? Good conversation piece.
 
I personally think the fact that you made it and made it from beer cans is just AWESOME!!! Maybe it could use a little refining, only to be taken as constructive criticism but again AWESOME!!!!
 
I like it, anything homemade (especially from beer cans) is great. It is even better when it works!
 
Very nice!


Is that beer all over the bike? You're supposed to drink it...
 
When I cast the slug, in my haste I forgot to add flux so it had all kinds of air pockets. I had hoped these would be minimal when I started cutting but not. I intend to recast it at some point and get a better polish.

The lid is attached with two countersunk screws. I haven't made the tooling for thread cutting, nor do I have the knowledge at this point. I like making the tools since they are cheeper, and it teaches me the use of the tool. Same reason I cast the stock in the first place. Very expensive to buy 3" aluminum rod.

I am looking to make Cam end caps and for certain a highway bar.

We went for a ride this weekend and I wound up with a dead battery half way out, so that takes priority before decorative parts. It's just not as fun:)

great for a first effort. you can buy off cuts from ebay of ally rod, really cheap. i made my own cam end caps with a lump of ally that cost me ?3.
keep practising and you will soon get the hang of it
 
I like that! A beer label on it to verify its source would attract attention!

Dont change it at all. You do not want some one to confuse it with a common part i.e. #xxxxxxxxx "Front master cylinder reservoir turned from billet aluminum, polished to a high gloss" on page 5714 of the HD after market parts list manual for brake parts!
Yours is unique!:clap:

What about porosity causing leaks? I'm all for home built parts but not so sure in this particular case.:-k
 
Hi,

I dig it. That's a good effort for a prototype. With a few process and materials improvements you could have a nice product. Let us know how it works and please show us the next one you fab up. Cool.


Thank you for your indulgence,

BassCliff

These are just air pockets in the metal. It has no leaks. After all, it is just a reservoir. It's not a pressurized unit.
