I need to use my late husband's jigsaw but can't get the old, bent blade out. How do I do it and which blade do I replace it with? I need to cut a few cms off the width of a kitchen worktop.
It depends on whether you have an older or newer model jigsaw. Bosch makes the newer ones with a button you push that will release the blade.
On an older jigsaw, look at the handle from above the jigsaw directly in line with the blade. You should see a screw in the top of the handle. Use a screwdriver and loosen this screw, don't remove it, and when the screw is loose enough, you'll be able to pull the blade out. When you put the new one in, slide it in the slot until it seats.
A rule of thumb is to use the blade with the wider gap and larger teeth on wood, the smaller teeth on metal. Most blades will say bimetal on the metal cutting blades.
Now, the courser the teeth the rougher cut you'll get. So, if you want a nice cut, don't use the blade with the largest teeth. Move down to the next largest.
I don't have a Bosch, so am not sure which codes are for which blades, but you can't go wrong if you go by the size of the teeth.
You didn't say what material the worktop is made of. If it's wood, the second largest toothed blade should be fine.
If you've never used a jigsaw before, I could suggest a couple tips that would help you get a nice job done.
First, put a piece of painters tape or masking tape over where you will cut, draw your line and go easy. The tape will keep the blade from giving you a roughed up top edge.
When you get near the end of the cut, hold a piece of scrap wood flat against the back edge to prevent tearout.
Also, let the saw do the work, don't push it.
Hope this helps, If it does, I'd appreciate a 4 thumbs up, Thanks,
