Jigsaws and plywood

[*kazumi*]

So, I want to cut some plywood into curved shape, and so I thought I get myself a new jigsaw from Bunnings.  I have owned some in the past, but I am not sure what the info they give means: They call it 75mm jigsaw and give

Product Dimensions

Width - 75mm

Height - 25mm
Length - 25mm

Can anybody explain?  Obviously it is not the actual jigsaw, and it cannot be the blade...

And then I am sure that the blade/s it comes with is too rough for plywood, so I want to buy fine toothed blade, but It's hard to tell from the piddly pictures in the listings, and most say wood, or metal and only one said ply.  I tried to save the picture and enlarge it, but they do not allow their pictures to be downloaded.   Nor is there any info which blades fit which saw.  I am assuming that when they bother to call it " 75mm jigsaw", the 75mm is important... I thought it might be the blade size, but when I tried to search for 75mm blade, I got nothing. 

I spent about half an hour, two times, trying to get some info from their "Live Help", then I emailed them the product names and numbers for the jigsaw and extra blades, asking if that is OK.  I got phone call back from somebody who actually has not seen my question, and when I tried to tell him over the phone, he did not seem to understand. 

Help!

you are looking at the ryobi 500 watt right?

the specifications say it has a 19mm stroke, thats cut depth

how thick is the ply wood your cutting?

i have no idea what those other measurements are about.

found a review on youtube

I was tossing between that one and the one up, and not sure if I should get cordless or corded.  I do have the Ryobi charger. 

the guy in the video tells me there are wood cutting blades, and metal cutting blades.....  YES I know but  Bunnings does not tell me which is which.  The only one that I found that actually said it is fine enough for plywood is this, but the top looks strange shape.  Will it be a problem?  With my old jigsaw, I would go to the hardware shop tell the guys what I am cutting and brand of my saw, and they would tell me which will fit and which is the right one. 

these are the blades I wanted to get

Diablo 3-30mm Wood Fine Jigsaw Blade - 2 Pack

The ply is about 5 or 6 mm

Yes, i think I know what I want = blade with 10 plus teeth per inch.  But the blades that look very fine have in the specification 2.7 teeth per inch!  LOL, just like the actual jigsaw is apparently 2.5cm x 2.5cm. 

I think I will have to wait until I can go in the store; I will not even need help, I will be able to see what I need. 

Thanks for trying anyway 🙂

Personally I wont touch Black & Decker tools of any description.

to me no real difference in cheap power tools

would i buy a ryobi? or any bottem end jigsaw

not if i wanted a tool to last my lifetime

you get what you pay for

i buy makita when i buy, but they are expensive, but i know they last and last

you can get parts if ever you need them

but if your just wanting a tool to use every once in a while cheap will do the job.

my jigsaw cost over $200 a long time ago, i suspect the price is a lot more now

but it is as good as when i bought it, i take care of it.

i dont think the OP was asking for recomendations for what machine to buy

everyone has an opinion on tools

someone else would swear by dewalt ect ect

Stihl is my go to.

No complaints from me.

However, I've never seen a jigsaw blade with only 2.7 teeth per inch. A coarse one MIGHT be 2.7 per centimetre. Even that is stretching it if using it in a jigsaw. I'd be looking at at least 8 teeth per inch for wood, and probably double that for metal.

Kazumi - wood is wood. Ply or otherwise.
