Being creative...And work my ass off...
 

So, its another new block from me, actually 3 but they are all the same. Did a clip too, but with a horrible finnish, I will fix that later:

:D

WOOOT! Man you do some beautiful things! I love the clip, reminds me of 'Space invaders' some 20 yrs ago...:p

lol, don't you have it when that happens? lol

nice work though!

(what size of millbit is that?>

may I also recommend some 2 flute mills? they don't clog as easy...

Nice work:drool: and the broken end mill... OUCH :(

Nice work :)

...and, a little J.B. Weld and that mill bit should be good as new :D ;) :p

Clog? 2? why not 4?

4 flute endmills clog up easy with soft materials. The groves will fill up with copper causing a serious lack of cutting ability, thus breaking the endmill. 4 flute cut faster but at the cost of clogging up and breaking. I have yet to have a 2 flute clogg up. Thats all I use on Copper and AL. And now that I found a good mail order suppplier near by all I use is 2 flute tin coated and carbide endmills. :) Use whatever works for you though!

nice work...

do designs like this perform well compared to jet on die area blox?

Fecking nice Chrion.

How deep passes are you taking?

How long have you been playing with the mill now?

My dad just got a full set of beatufil number and letter drills. I broke one :(. It will probably be salvagable. Damn you cloggy copper!!!

0.33mm/pass
i've been playing for some weeks now, sadly I only have the time on weekends :(
but it is fun! :D

Are you going to solder them all or use screws to mount the lid on some?

I really like that hold-down! Sweet!:cool:

:eek: :eek: Thats not helping the breaking problem.:D I usually go .03125 on the first pass and .125 on the rest. No matter how big your mill is you don't want to go to deep or the endmill will break. Unfortunatly the endmill is the weak link not the mill in most cases. I can easily break a 3/16" endmill on my tiny desktop CNC mill.

Are you planning on trying a center inlet version with two outlets (as might be suggested by the hole in the center of the hold down)?

WTF. I can do much larger passes than that easy (unless you are talking in inches which ChrioN is not).
1mm passes are like a hot knife through butter.

I can't wait to see that all polished up :D

.. you are gonna polish it, right? ;)

Yes, I mean inches not mm. Keep forgetting I am in the US and quite a few here are not.

i would use
 

2 flute mill bits by niagara
with TiAIN coating

those are the shiet servive way longer then generic

Ok, understood.

Endmill breakage is also of function of length. You always want to use the shortest EM available to get the work done with. You'd be amazed what kind of stock you can hork out with a short EM.:eek:

back in my uninlightened days, I took a 1/2 inch pass w/ a 1/4 inch endmill and got a good finish...

but sweet jbus those are nice looking!

I can't get my CNC mill to go slow enough to go over 1/4" deep without snapping the endmill or causing the stepper motor's to slip the shaft. It's slowest settings are just to fast. If I use the hand wheels and leave the CNC off then I can go pretty deep, but it is sloooooooooooow. I ran a 1/4" deep M channel design out it one pass in Copper once. Took for ever but it did turn out nice. Which reminds me I need to dig that one out. :D

, I suppose it helps to have a 1 HP bridgeport... lol

I wish I had a CNC!

GAH!
This block didn't perform as good as I wanted.
Only a couple of degrees C better than a Maze2...
Guess I got crappy coppar...or the fact that I didn't go for the inlet over the core.

I'd say its the design. No inlet over core and a lot of the block isn't really doing that much.

Heatsink are big cause they are slower to get the heat away. You want the heat out of the metal as quick as possible, therefore a die inlet is best. See Cathars block for the current best WB design, and you can make something not too dissimlar. (Including G design etc.)

I was doing .09inch passes on my mini mill today with 3/16inch ball end mill.

-edit- can do more than that, but its faster to do less,

so you can just fly througg 1 tenth? how fast about?

pretty nice, but kinda slow, .05inches seems best for speed to depth ratio
