Topic tags/keywords: jointer

I am looking to replace my 6” jointer with an 8”. The parallelogram jointers cost a few hundred more than the standard bed jointer. My old 6” jointer gets moved from one side of the garage to the other every time I need to use it but I have never had to readjust the beds since I got it. I’d like to hear from those of you that have used both and get your opinion. Which would you recommend and why.

when I was buying a big jonter, I had the budget to either get an 8” dovetail with shelix, or a 12” parallelogram version with hss knives. In the end I went with the 12” for a couple reasons. One I wanted that capability to adjust my tops in more than a single plane. Now if you ahve the dovetail and it’s perfect then odds are you will be fine. However if you have an issue the only way to adjust is with shims. That concept did not appeal to me at all. I’ve had my 12” for 9+ years now. Never adjusted it. It’s been moved across the country into a basement so it’s been bounced around. Other than a knife sharpen, I rarely change any settings. However I would want that capability.

I think in the end it comes down to budget and whats important to you.

For me I wanted the biggest jointer I could get. I thought I’d get the 12” and upgrade to the shelix head later. Never done it as it does what its supposed to do so I’m good with it the way it is for now.

Thats my opinion but that and a buck fifty will get you a cup of coffee. Good luck.

Hello Julian,

Maybe this helps. On this side you can download and /or see planer documentation. The world biggest manufacturer of proffesional woodworking machines. Only the big types have a parallelogram system.

It is worth it to me. I’ve had to adjust for coplanar a couple times on a dovetail style jointer, and once on a parallelogram, and it was sure nice to dial it in so easily and perfectly on the parallelogram.

It has made a difference to me. My old 6” dovetail way jointer needed periodic adjustments to stay coplanar. When it would sag, it would start cutting tapers again. Some adjustments need to be made by adding brass shims.

Now I use an 8” parallelogram jointer, and it stays dead coplanar despite heavy use. Adjustments are made by turning cams at each corner of the infeed and outfeed tables.

Size is the biggest factor. Any 8” jointer is better than a 6” jointer. Bed construction is a close second for me.
