Sweet looking how much??
Hey ricky, your evaps are much better than your English; just joking. I think I do not need to tell they look superb :toast:. If performance is as good as cosmetics, then it´s a winner ::cool:
well, if they dont perform better than my english i'll shot myself :S
anyway my engish have had worse than now i think :D
|RickY|, I want one for testing :D
Awesome job, hope it perform well !
holst: here is the pic :)

lukeXe, for sure
Negative Rake? Must be one powerful lathe... :)
jinu117 what do you mean with negative Rake?
(my english sucks)
I guess he means the angle the cutting tip attacks the machined material.
Gotta be better than the lathes at my school :D. They wouldnt' cut into my copper without it making the loudest grinding noise i've ever heard... Even with a very sharp tool, fast rpm and very slowly...
how deep were you going?
i has cut copper on a tiny 12"X6"X4" table top CNC meant for plastic or wood.
just go in slowly!
I was trying to make an evap from a bar of 38mm solid copper.Quote:

This is the lathe I was using. Sorry I only have this and 1 other picture a little closer up. (Phones are banned from our school so I have to be quick so I dont get caught :p: . Its also only a 2mega-pixel camera on the phone :) ).

I looked in our garage and found some of that isopropyl alcohol. Do you need to soak the evap in it? Or does it just need wiping with a cloth with a small amount on?Quote:

Here is the lathe I have, it's more for R&D and for finishing up not so good finished evap or sleeve for exact fit I like. Backlash has been adjusted to about 2 thousandth... Only bad thing is, I have some play on the table itself which I can't figure out how to fix short of making new gib for it that has better tolerance... -_-; I believe this probably is cheapest lathe you can find ahaha...(it's commonly called 7x10 mini lathe)

Here is what I played around with recently just for toying around using it. Of course, I was cussing myself every minute or so complaining how underpowered this lathe is. I ended up grinding the tool to reduce friction as much as I could so the small dinky motor won't just keep stop. It has self preserving feature to prevent major disaster from happening which in this case was slowing me down a lot.

Nope, I have no intention of doing more than few once in a while just to remind myself not to use this lathe for this use... :) But for those with patience and want to DIY, lathe is relatively inexpensive to toy around until you start upgrading things... :)
Im sure the parting tool was set correctly. My teacher checked it many times and said it should be fine.
Anyway, this is what I ended up with after running out of time. I had to take the bar out the lathe and saw the evap off with a hand saw:mad: . Thats why you can see a small ledge on the right side.
Btw this was supposed to be a stepper evap. I didn't bother using it because I doubt I could find a sleeve to fit it properly.

I have been looking for some pictures of the bar while it was in the lathe but can't find any :(. If I find them I will upload and post them.

undercharged of course, need to put on a cpu to see how good it is :)
Wish I had brazing equipment that could get that hot :p: !
Sweet pics Ricky... What a job! Amazing! ;)
that evap looks good ricky, if you can when drilling those holes throught the bottom layer dont make them too large as it wont be restristive enough.
Be interesting to see the results between a normal evap and one with the channels same size etc.
more 2 alrready shiped

brett looks like your bit ground wrong or height is wrong, its chattering for you.
are you using the tail stock?
sorry my english dont help-me can you explain better? :SQuote:

No he means the spindle that is at back of actual spindle turning for lathe job. For parting cuts, it is recommended NOT to use tail stock as part are meant to be fallen off instead of getting crunched in between when job is done and potentially breaking parting tool, flying, out, hurting someone, etc.Quote:

looks like bit may be dull or ground wrong.
sorry can't teach that in words.
