Mine just have a wedge to hold the handle in and can just tap it down some more if it loosens. Good knowledge you have passed on there.

Well after the success of repairing the other set of bonnet louvers, thought I would try making some from scratch for the side of the cowl that better matched than the ones from the FJ45. Transferred the shape of the louver to some 8 mm/ 5/16" flat I had. Used a holesaw to get a start and then nibbled away at it with a jigsaw and then a file. This is a little thicker than the height of the louvers, but would allow for some spring back. The middle part was cut out just using a angle grinder. Tig welded it onto more of the same flat to get a good base to it and stop the sides from spreading. Filled it with oil to cool as might add a little hardness to it without getting brittle like a water quench. Using a great tip from Per, MetalMan Sweden, I used a wood chisel sharpened with a curve to the end to cut the metal. https://www.youtube.com/watch?v=vIPZUUPPTFk Could also drill a small hole at each end and use a thin cutting disc, but leaves a bigger hole not covered by the louver. Used a bit of very hard red gum to shape into a forming tool. It is important that it is the full width of the louver. First louver done on new metal. I made sure the thickness each side of the lower form I cut out matched the spacing between the louvers of the bonnet ones. I found starting in the corners and lots of small taps to just cut through the metal and no further worked best for me. I scribed lines to follow where to cut and made sure the metal didn't move on the form. You need to hit down right on the very edge for it to work. Halfway there. Quite like just the three as would match the ribbing, but have done the calculations and not enough area to match the intake of the A/C unit. I kept the form straight to get consistent shape. The corners need to be a bit ahead of the rest and use plenty of light taps with the mallet working back and forth like a reciprocating machine. Matches the shape of the template pretty well. One thing that did show up when I did this one starting from the top, when forming the next louver, it tended to pull the bottom of the louver above it into the form. I have just started the second one and doing it the other way and stays straight and flatter as have more metal above it. Seems to be matching quite well so think they are will be good enough to use. I will redo the first one though to get it to stay in better shape. The bonnet ones taper in length which is not needed for the cowl sides. So took the length of the middle one which was 152 mm/6", to make the new ones. That is an inch longer than the original side ones from the Landcruiser.

Thanks for the write-up. I'm sure I'm going to try it the same way. Greetings, Frank

Marcus....very good job you doing here!
I have follow your work and your solutions to tackle problems is nice! Cool that you find a way to create louvers, you can not dream about how many Fiat Topolino bonnets I have repaired and replaced, they have plenty of louvers to make, I have just used this simple handtools Keep up your fine work! |

Great Job Marcus. I did some small ones on my beadroller electrical box also using Per's wood chisel abuse method.

Just saved your louver work, to a PDF format, on to my computer.Great results, and something I have been thinking , to try.
Question: If I would like to do the louvers to a curved shape, would I just bend the template plate, to the radius of the surface, where I am going to make the louvers?? ..Hard to explain
