Now now boys, Real men know that Kawasaki's aren't evil,
Everything worth writing about those other brands can be found on a T shirt





wait til you see the heat guard i made for the husky...15 mins, a jig saw and a rule of thumb...im giving it 1/2 to 3/4's of a lap around blackwood...

1/2 to 3/4's of a lap eh?
Are you intending on crashing out or breaking down?
If you are able to define the spot a bit better it would be a great help to the sweeps that are going to tow you out :o

I put a subliminal message in it that will make you want to make Paypal gifts to me ;D

Next step is to work out what size piece you really need.
Laser cutters quote their work based on the total length of cutting and how many stops and starts.
This piece looks to me to be bigger than what is needed so it would be wise to trim it down otherwise you will be paying for the cutting of a lot of holes that you are going to throw in the bin

Gotcha;



Also 1.2 sheet will most likely measure 1.1mm

Something like this?

Also most places have minimum charges, fair enough when you consider the guy on the fork lift has to get the sheet out of the rack and take it to the machine where it has to be lined up and then the program loaded into the machine.

Its not usually economical to cut a one of but laser cutters are happy to cut any shapes out of the same material so the more bits you need the better.

While you can scale close from photos you would be better to go from measurements where you can.
Obviously you want the shields to look like originals so best to get it as close as you can otherwise you could use any old thing.
No ones going to notice whether they are 10mm or 3/8" holes but a different pitch will stand out.

As Momus says 1.2 =18# and 1.5 = 16# however the US may run different specs?

Perf sheet is usually punched out a row of holes at a time, you can get perf made in a turret punch but they will only punch one hole at a time, even though the sheet will be moved around by CNC it is still a slow process and needs to have the right size punch fitted to the machine.

Laser cutting is great for cutting out intricate shapes but there will be a small dag where the laser stops and starts in the hole but it is usually very minor. A plasma will leave a bigger dag
It will produce what ever size hole you draw, any difference is not worth measuring

My CZ heat shields I have laser cut in 1.2


Plenty of laser and water jet cutters these days, water is slower and best suited to thick materials
Most will charge you a programming fee
I get stuff laser cut all the time and draw up my own CAD files, can easily draw up your perf if I have the dimensions and get a quote for you or you can use the file to get your own quotes

"it's satisfying to make a tool and have it work the way it should."
I'm hearing you, I have made a few bits and pieces over the years although some a bit more crude than your work.
A pair of dividers I made from stainless that don't flex like the 'bought' ones, made in my apprenticeship and still used to this day.



"You realise that they didn't stop making the wooden planes because the performance was not as good as the metal planes, it was just that the metal was much quicker and easier to produce."

Same as my belief behind aluminium frames

Agree, very nice work Zane, I'm even more impressed as I don't do wood

Hope these tools don't turn up as an ALDI special buy next week ;D

If you don't have anyone locally to do it I can organize it for you
I would need to know the pitch of the holes in both directions if they happen to be different

Bit difficult to measure thickness as its edges are folded and I cant get the Mic in there as its too close to the pipe.

If you can push something through one hole to hold behind another hole you can measure the depth with the end of a Vernier

My guess would be 1.0 or 1.2mm, I highly doubt they used 1.5mm

Large holes like 3/8" or 10mm would mostly be made with a thick material like 1.5 because most perf is made for industrial applications.

If you really want it to look original then get a piece laser cut or go through the pain and drill a sheet, most of the work is marking out the centers

Apologies Mike, I meant to reply but got sidetracked, due to the distance I put it in the too hard basket.
Good luck with moving them on.

I have a a broken Brobo blade here (Doh) your welcome to for the cost of postage, I'm guessing $13.80

500 too much for me at my advanced age ::)

From what I hear an 80 would be too much for you at your age ;D

i note carefully the Honorable member for Broadford has failed to mention the miserable performance in the mx section he is responsible for...

Suppressed memory
We were supposed to watch the flagman to drop the flag for the start but dickhead me was watching the wrong flagman, was wondering why everyone was jumping the start then realized I had been left behind.
It was hard work coming from behind on the KLX
