What's the best way to avoid bevels when curve-cutting a piece that's 1.5" thick?

My jigsaw puts too much bevel in when I cut a long curve in a piece of pine even if I use light pressure.

And the worst part is the bevel is opposite on the opposite side of the piece I cut – not good. So I get tired of sanding and planing the bevels off to get 90 degrees.

A thicker blade would help – and just a better jigsaw would help – like a Makita high-end?

Just curious which direction I should go – high-end jig-saw or small circular saw. A circular saw is hard to cut a curve but it would give 90 degrees. But I lean towards just a better jig saw – is there one with thicker blades or a better guide that doesn’t allow the blade to bend? My jigsaw just won’t cut it – but it only cost 25.00.

please tell us what saw and blade you are using now.

that is the same issue I had for years until I finally asked the
Dewalt tools salesman and he said I need to get away from the
“up and down” action and buy a jigsaw with the reciprocating
“swooping” action and a coarse blade. worked great.

That’s a job best done with a band saw. If a jig saw is to be used, you could sandwich the piece between thin plywood if you can get a blade long enough. The plywood would take the bevel leaving the work piece with square edges.

I had the same issue until I bought a Bosch jigsaw and Bosch blades. As mentioned that oscillating feature helps as well, and going slow. The other option is cut the waste with saw and then use a router with flush trim bit with bearing on top.

+ 1 MrRon. The best way is with a band saw. For a piece that thick even a good jig saw will wonder.

Maybe stabilizes the other end of the blade somehow?

I will try some of the ideas that you’ve presented here – and I will get a pic of my jigsaw for John Smith’s request when I next go out to my garage. But one idea I will add to the mix since I’m still at the experimental stage is a small either 4 1/2” or 3 3/8” circular saw. The curves I’m cutting are gradual – I can probably use a circular saw – but I have to first prove this for the 54.00 it will cost me. If it doesn’t work, the next thing I’ll try will be the Bosch per SMP’s response. And as for the bandsaw – I need to find someone who has one as I do not have one. But I know of a guy who advertises that you can use HIS tools – in his shop – perhaps he has a bandsaw – or perhaps I need to buy one. I currently have no place to put a bandsaw – no room at all, which is a shame. My first piece is now planed and sanded and at least it’s doable with a junky 25.00 saw. I say junky because the blade-guide doesn’t do a good job – I’ll post a pic – perhaps I need to tweak some adjustment with an allen wrench to the guide?

One huge problem with circular saws though – most of the 3 3/8” or 4 1/2” saws can only cut a depth of 1”.

There IS one by WORX that cuts to 1 11/16” – but where to buy it? WORX WORXSAW WX429L Compact Saw

I think Home Depot might have this – but is it in the store? I have to have it shipped – which is ok.

I’m sure this family handyman link makes it look easier than it is although they do give you some warnings about blade depth, bending, heating, etc..
https://www.familyhandyman.com/woodworking/how-to-cut-curves-in-wood/

My curves are about 25% or more MORE gradual than in the pic in that above link which helps me some.

BY THE WAY: I plain and simple would not be able to do this job with a router. I just don’t really have the means to do a good routing job other than the simplest. I would make a mistake.

BTW, I got an older model Bosch used on ebay. IF you are patient, you can get a good deal there or craigslist, offerup, etc. I think I paid around $50 for mine. THis one the guy is charging an insane amount of shipping, but you can surely find a deal if you wait( I have this models, works great):

I had similar problems with my cheap old B&D jigsaw. It would not cut at 90 no matter what I did. Finally gave up on it and bought a PC jigsaw. No more problems. Cut curves on the tails of of 2X6 redwood pergola pieces without a hitch. Restored my faith in jigsaws.

Thanks for the blade info SMP, that should help.

And Little Shaver recommends a “PC” after ditchin’ the B&D. Does PC mean Porter Cable? And where can I buy one?

So I will do my next one with either a new jigsaw/blades or circular saw, but lean towards the jigsaw once I get a new one.

Below is the tools I used, including the B&D JS 515 Type 1 (in answer to John Smith’s question) which doesn’t stay straight enough for me so far.

So I would give myself a B on the top and a D- on the bottom (scale of A to F, but those are BOTH passing grades lol, even the D-). The top is actually almost perfect. The bottom is a piece of … well I won’t say it.

It’s pretty near an equation of:
Shi’‘y tools = shi’‘y job
An F but one more try might work.

The car is not for sale. Everyone always asks cuz it’s nice.

So far, I see a PC at Lowe’s but it’s cordless, can I get a better one?

Porter Cable PCC650B 20V MAX this is on Lowe’s.

Yes, PC = Porter Cable and I did buy mine at Lowe’s about 6 years ago, but it has a cord. I am partial to PC tools in general, but limit my cordless tools to drills.

I did find this one on the Lowe’s website: https://www.lowes.com/pd/PORTER-CABLE-6-Amp-Keyless-T-or-U-Shank-Variable-Speed-Corded-Jigsaw/50249023

I;m at the office now, so I can’t verify that this is the one I have, but it appears to be close.

Not sure what you have but I think I need a PCC650B – they have a thin vs. curve setting and safety features and the LI ion battery charge they say lasts 18 months. Well anyway, I need to find that tool.

Yours is the PCE345, which might be good enough for me, particulary if I can find it. But I might even order two of them?

Hell, if the PCE345 cuts 2” redwood, it’s good enough.
