Got myself a sheet of aluminium today from the local hardware store so that I can make an air box for the pod filter. I've got the template all trial fitted so the only thing left to do it transfer the design onto the alu sheet. The only problem I see left is cutting it. The sheet is 0.5mm thick so it's not too thick. Any suggestions?

I was thinking of tin snips, they'd be fine for 0.3mm ones but i'm not too sure about 0.5mm...

Will hack saw work? theoretically, they are somewwhat "manuverable" for cutting odd shapes.....

I would use a tin snipper or an angle grinder. Depending what types of shapes you're cutting out, the hack saw could be some help if you've got one lying around. I wouldn't use a hack saw myself, I'm such a newbie using one. Snapped about 3 blades trying to cut one little piece of metal rod. :P

you sure its half a mil. thats heaps thin. wouldn't be very strong??

use a saw of some kind (jigsaw, hacksaw). aluminium just clogs up grinder discs and then they don't cut properly, the metal is too soft. if you have to use the grinder because you have no other choice go and get some 1mm stainless cutting discs, they work ok, not the best finish.

This is a weekend DIY thing so what every tool I have will have to suffice. So plasma cutters are out of the question.

yeah I'm sure they are 0.5mm and the reason I got it because it seems thin enough to cut by myself without having to enlist the help of expensive workshops and just strong enough to be useful. This is afterall just for fun. I'll try the hack saw and see how that goes.....if I can't find a hacksaw i'll have to get a tin snips....it seems to be a tough job cutting with tin snips though. We'll see tomorrow.

if you want to cut allumium with grinder you will need the "green" cutting disks also known as silicone cutoff wheels. I personally would use a jigsaw with the appropiate blade. Ask bunnings for which blade. Or use your head and rear the packet

got a circular saw?

as mentioned the alloy can clog a grinding disk, then over heat and (for want of a better word) explode. these flying parts can kill you, it has happened before.

you could get yourself a drill powered Nippler, these will not warp either side of the cut so you dont waste material.

if ur in perth pm me i can cut it for ya at my work. or else you using a hacksaw (will take some time) or jigsaw (just make sure your using a metal blade which is for metal and for the 0.5mm thickness)

Tin snips are the go. But there is a trick to it!

First cut out the piece fairly roughly leaving maybe 10mm of material extra beyond the cutting line. It will be tough going, and the sheet will buckle and wrinkle along the cut, because a big sheet cannot curl as it is cut.

Once you have got that far, the edges will look pretty rough wrinkly. Cut again, but this time leave only about five mm of material beyond the line. Because the piece being cut off is now very narrow, it will curl easily and the cut edge will be very clean.

Go around a third time, but this time cut right up to the line. It will be very easy to cut around fairly sharp curves, and come out with a nice clean cut with an undamaged edge, right on the line.

If you want to avoid scratches, stick wide masking tape all over the sheet, and mark out your shape with a ball point pen. Do all your drilling, cutting, filing and folding. When the whole thing is completely finished, peel off the tape, and it will have an unblemished surface.

    • Hello Liam - HA - somewhere in flies - possibly I have an update, but I have been so busy, projects have taken a back seat to getting business back on track.  I will let you know the outcome, but I think I am going to go for the 8HP,  CHEERS.  ELVIS
    • Thanks Joshuaho96, yes - as someone else also suggested, the 8HP seems the 'smart choice' - HA - and ZERO to do with cost, but I am sure 8 speeds will be better than 6 speeds - HA - maybe.  I will purchase a new 8HP,  Thanks.  ELVIS.
    • Nobody said anything about getting a "...cheap Falcon box..."- it was JUST a question about a specific transmission.  And YOU may have a problem with not enough $ - HA - I do NOT - so please keep your comments like you are some financial guru to yourself.  BUT - much appreciated re the cost of a new 8HP and I twill probably be the way I go.  Thanks.  ELVIS.
    • Most people I know in the BMW world are swapping 6HPs for 8HPs. The 6HP has a big issue with one of the clutch drum bushings wearing out shockingly early which leads to them going into limp mode going into 5th/6th gear as the oil pressure loss from the worn bushing causes clutch slip. Even with the adaptations in shifting the TCU can't bump line pressure enough to keep the clutches from slipping and burning. I've personally looked at a 335d with 6HP28 with one owner and ~90k miles on it and the transmission adaptations were way out of spec and even though it nominally drove ok I'm confident it would have needed a full rebuild sooner than later. Other than that they're fine, but the 8HP doesn't really have weird issues like this to my knowledge and they're in everything these days so pulling them out of crashed cars isn't too hard.
    • There is an ABS pump and a few solenoids. You could trigger the front/rear solenoids with a pressure bleeder attached with a Consult 2.
