Casting Aluminium Roundstock From Free Scrap 

+1 for this one, and when you're done, use it to clean up the parts as in my other suggestion :D

i made a video about my homemade belt grinder i'm 14 years old

At the beginning yes

lol I think he's joking cause he mentioned it so many times

;-)

This question is up with the "what's the meaning of life", "is there intelligent life in space" and "how much air is it in a lays chip bag"..

Adventurer From Sweden 42... Seriously though, is there any intelligent like here on earth though

+Sean Britton did you mean "life" not like. haha sean I think not.

Every aluminium dealer :D He makes them redundant. ;)

bad people with nothing better to do than troll the interwebs

k torgs bahahahahhahahaha!

techinically he is

At least he sounds smart

google kalapappi if u have no idea what i just said

Why make a bat for fishing?

+glockfan112 a knife is slow and bloody

Always use a knife if you want to keep the fish good... You need to let the blood out of them.

its a club for killing fish right?

harbor freight has semi decent lathes for reasonable prices

+Samuel Scott thrre for woodworking I thought

lathe and well equipped workshop. This guy is just lucky having the right father. Without this, he wouldn't be able to make those projects.

A woodworking lathe should actually work fine for aluminium since it's so soft. You'll need to make your own milling mechanisms though.

try craigslist just always be looking you eventually find one cheap or David gingery it out

Absolutely sure. You can not reverse the jaws of a scroll (self-centering) chuck. For that reason most scroll chucks are supplied with two sets of jaws, one set for each direction. An independent 4-jaw "universal" chuck has reversible jaws. It is driven by a dedicated worm gear for each jaw. The scroll chuck has a spiral drive (tighter radius at the center than at the edge) requiring a very unique, precise shape to the teeth on the back of the jaws, curved in such a way that it will be tight at all points along the varied radius scroll. Turning it around means that the curves cut in the back of the jaws are directly opposed to the curve of the scroll drive gear. Just get a 6" 4-jaw universal chuck for handling larger and square stock. Under $200 US, shipped. I believe your lathe has a 1-1/2"-8 threaded spindle, but you'll want to verify that before ordering.

+Jon Miller I own a proxxon pd230/e and it came with a 3 jaw self centering scroll chuck and the jaws are reversible. I just change the order of the jaws from 1-2-3 to 3-2-1. They do exist :-)

+orpantattoo Fascinating. It appears that their documentation is poor, so I can't see anything regarding how the chuck operates. Judging by the visible appearance of the chuck (more like a drill press Jacobs chuck than any other lathe chuck I've ever seen) it has a different mechanism than any I've seen before. What do the teeth on the actual jaws look like? Teeth on typical scroll chucks are curved to match the spiral drive gear ("scroll"). Because of that curve they can not be reversed. You would have to make teeth which are an intersection of the profiles for the two directions, which would mean that they are smaller, giving less bearing surface and therefore less strength, lower precision, and less available wear surface so they would also wear out faster. And they would be more difficult to machine, assuming that the goal is precision, making them most likely more expensive to produce than separate sets. Thank you for sharing!

+Jon Miller the chuck is actually much like any other scroll chuck, the only "odd" thing about it is that the gears are external. The teeth on the jaws have an oval shape so you're absolutely right about it beeing a crossection. However I doubt it matters as the teeth have full contact on the side where the "spiral" drives them when holding the workpiece from the outside. When holding something on the inside it does however have a smaller area of contact. But i rarely do that. It is a VERY small lathe after all :-)

That type of scroll most probably wouldbn't work on a larger lathe like the 9 inch south bend the author has, which is why they don't exist in that size. Your lathe has a 2" swing (in American terms), his south bend has a 9" swing.

You can also make a crucible that pours from the bottom (think gravy boat).

Or turn between centers.

He said in the video, it was a fire brick. Same thing he used in the making of his furnace, probably a left over piece.

HaydenHatTrick you can use paint thinner or some other solvent more than likely.

true, thanks for responding (considering the number of typos I made :P)

Drill a hole off center in a piece of round, hacksaw a slot into the hole, then you can clamp in the 3 jaw and turn off center. Problem is tailstock support....

You could use a steady rest as support but otherwise you could drill holes in the end of the cam in some extra material, then cut off later....

No actually not, That is a scroll chuck, which means the teeth for the jaws are cut for working only one way. They teeth have a complex curve that matches the scroll that is turning when you tighten the chuck key. An independent 4 jaw chuck is what he really needs to open up real possibilities with that or any lathe. A little bit to learn and a bit harder to center, but a 4 jaw will allow much closer centering tolerances, and the ability to turn non round stock.

A lathe would be dreadful whilst making grooves for a handle

Andrew Cline four jaws are reverse able not three jaw

same result by just letting the aluminum cool slow, not dunking in water and tempering your writing about normalizing.

No i don't i'm talking about artificially aging the metal. You don't normalize Aluminium. You artificially age it so the crystaline structure reorganizes and settles. And no you dont get the same result with just letting it cool slow. There is list of steps to take to reach a T6 or similar. Pick up a metallurgy book, old navy manuals is the good ones for hobbyists. Good luck. =)

***** oh shit, I've made throwing stars and I live in the uk

***** k

It was flux he got on the net, it was mentioned in an another comment: Jennova Slyne100%boric acid is available at dollar stores as roach and ant killer just check the back ingredients cheeper then flux on the net and basically the same thing at least it works the same way
