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.

      Are you an oil nerd?

      I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet.

      Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
