Got bored playing with the dremel on acrylic so decided to cut the real thing. Been postponed for way too long. How to avoid overcuts like in pic 2's top right corner? I don't mind them cos they're gonna be covered (think of the front panel 120mm below the ROM on American Apathy). But I do keep smaller burnt out discs just in case they'll work for corners.








Yes, I'm up to no good again =) But no cuts filed yet

perhaps filing that corner will make it perfect ??

dont cut into so close....use some files to finish up the corner

1st thing to do is , hold the tool correctly and pay attention to the cut ur are cutting dont gengam the tool till ur bones pain . like u wanna do that 90 deg i suggest u know the part |_ the vertical line, u cut almost to the end dont cut till de end just cut almost to the end about 0.5 cm from the end same goes to the horizontal
after that slowly speed 4,5,6[ ganas ] run through abit by bit then go to the horizontal line and slowly till u almost reach the once slight touch it will come off

in the relax way of cutting take a chair and sit and cut through it as more it will be more stable as my waist usually rest on the casing ,try it it may help
I usually take a table fan as to cool down me sometimes to sweaty irritaing

I'm still at noob speed 3 at the max lol... need to get more cutting discs.. the one i used not reinforced ones, cut that 2 holes used 2 already

its like that once u get used to it , u can put higher speed or max speed but have to becarefull lo 6 speed pay 100% attention

I do it on ground, at least more stable with elbow on the case itself or a prop (chair or box) for support. Snapped 2 discs but luckily not flying my direction. Well.. time to give my neighbour some payback after they woke me up for countless times with their home renovation before CNY.

p/s: #$*@(@&#&%(# I bloody hate photobucket. any other websites for hosting?

never expect the dremel to make the perfect corner. use files to do up the corners. another thing that you may want to bear in mind is the cutting rotation direction, then nearing a corner you might want to cut with the dremel rotating in a direction that cuts by spinning upwards to the cut... not downwards... hrmm... how to explain that... like u know, the dremel spins clockwise with the handle facing u...when cutting towards the right hand side direction, it has a tendency to climb up the surface being cut, thus possibly causing overshoots or grinding unto unwanted surfaces. whereas if you're cutting towards the left hand side direction, the dremel digs in; it will never climb up. I normally do this when nearing a corner.

I normally don't mind which cutting direction on long straight lengths except when I'm cutting intricate stuff, I always cut towards the left to prevent overshoots and jumping/climbing mistakes. bear in mind that when cutting this way, you will have lots of dust and shards flying upwards. make sure you have goggles/specs and a breathing/face mask. aluminium or steel dust ain't exactly healthy to breathe in.

I noticed the direction thing you mentioned, so I didn't drag it to the left in case the disc breaks... but when I cut I put slight pressure while taking it from right to left (lift and put, not drag) and the cut goes thru faster, but kicks up lots of steel dust in the air. Is that the correct way? It takes extra to go full cut from left to right than the opposite.

Added on June 11, 2007, 10:06 pmAh, got it... was pretty confident its a perfect straight cut (although cant see with the masking tape there) so risked my face and the disc by slipping it in the line and grind the side =)

must draw nice nice then only cut

dun cut till the edge, instead after the cut file it into the desired cut edge.....this is the best method....but this dun work well on aluminum though hehe...beware

How come they don't work well on alu?

, n00b here... what are you guys talking about file?

Wht has drawing nicely 2 do w/ overcuts�? No matter how nice the drawing, if ur technique of handling the tool is not rite, definitely there'll b overcuts


Dats true but if u can master the handling skills, can cut as close as 1mm or less w/o single error


I assume wht he's sayin' applies only to thin aluminium sheets



File = Kikir

file = kikir.. thanks for new vocab in my dictionary..juz knew it

must scetch at the side panel first bcoz
dont want over cutting. so easy on the process

hmmm .. from my experience with steel, acrylic and aluminum ..

the method just differ from one another ...

on steel u have just got to be extra focusing ...

whenever u reach close to the edges ... use a fresh disc and cut slightly more to the excessive side to ensure u have more room to move the disc without breaking it..

after u have make about 2mm more of gap to move around the disc between the cuts. slowly very slow at speed 1, move the cutting disc close by the edge.

with such precision, you won't over cut or break the disc ....
