Hi
I am making a hood for an aquarium, which should be really simple if it wasn't for the fact that the aquarium has a bowed front.
I have a jigsaw and the softwood I am using is 44mm thick.
Do I need to get a special blade for this? The curve is very slight.
Any advice appreciated!
thanks

Hello and welcome!
To manswer youir question, not really. Just get yourself a good quality blade, such as Bosch, Irwin, Makita or Festool, turn your orbit down to 0 or 1 and go slowly. Best blade for the job is probablt a T244D, although they can be hard to come by so a T144D will do almost as well. A coarser tooth blade will clear the chips better than a fine tooth one.

Wosser problem exactly?
Needs to be a reasonable quality saw. Do a trial cut on some scrap. Either your saw will cut OK or it won't, in which case you look at replacing the blade, or the saw, or another method altogether. Make sure not only that you can follow the line, but also that the cut is perpendicular without the blade wandering.
One simple trick is to use a bit of the off-cut as a sanding block. It will be, mysteriously, exactly the correct radius! If you do much shaping with a curved sanding block, work you way through the grit sizes starting with 40 or 60
cheers

Welcome to the forum Molmol  Not a lot to add to the above other than if you do find the blade wanders cut away from the line and use a plane to shave to the line . |

If the curve is very slight, you could do it all with a plane. Given that the cut with a jigsaw will probably need cleaning up anyway, you might as well do it with the plane in the first place and not bother with the jigsaw. Cheers  Paul |

two thoughts, if it is not structural, why not kerf the back in the middle and just bend the wood otherwise, make a former, and rout the shape using a bearing controlled cutter. paul |

former is made by bending a thinner section of wood, for instance 6mmply  paul |
