I think the most important consideration is the length of the bed. There are a few 8” options that don’t require 220v service and there are a few “long bed” 6” jointers that can give you some additional length, but those of the 8” variety, if space isn’t much of a factor, would probably serve you better in the long run. Finding an 8” jointer for less than $300 bucks might be the hard part.

You never need the extra capacity of any tool, until you do.

Truer words have never been spoken.

On that note, what do you think is the minimum length bed to avoid buyer’s remorse? The JJ-6CS models look to have about a 4ft bed.

If you can get a decent JJ-6CS for less than $200 that’d be a hard bargain to turn down. On the other hand, there are plenty of folks that use their table saws for jointing boards. I’m a big fan of Jimmy Diresta and watch his YouTube vids all the time. I’ve never seen him use a jointer. I don’t think he even owns a jointer.

Dustin, you are asking a lot of different questions about a lot of things. Let’s take your thread title to start with. Difference between 6 & 8 jointers. Simple, 8” gives wider capacity, stronger machine and motor due to higher capacity, physically bigger machine so you have longer bed to work with. There it is, question answered. Now, there are tons of people who own jointers so they have no need for a planer. Jointers can and will joint edges and faces of your boards. Next item, I have been playing with wood most of my life with the last 18 y, being more “Fine woodworking” I don’t have, and never will have a need for a jointer. I never buy wood from the borg or milled. All rough, mostly left over center slabs from a veneer company. Veneer is cut from green logs that are soaked in ponds for weeks to soften then for easy cutting, just think about what the leftover slabs are like. I have a planer that is the most important tool I own. It does all the smoothing out and thicknessing of my wood. I use a simple router with a straight edge to joint all my lumber. My lumber from the main source requires 2 years drying time before use and I am cafefull on how I stack and sticker it to prevent warpage and cupping. On the rare occasion that I do have some, I use tablesaw and planer sleds to clean up the mess. With 2 sleds I built I can take any rough lumber and turn it into S4S ready to assemble lumber with just my Ridgid planer. You can do the same thing with your rough lumber with nothing but a jointer, and yes, 8” is better and 6” for many reasons. OK, my Pneumonia is still not over, so I’m done for now. Dustin, Read and understand the answeres everyone offer to your questions, then use followup questions to continue.

Posted while I was typing slow. You are trying your best to make the small stuff your major concern. 6 or 8….8 is bigger, bigger is more capacity. Benchtop 6” give you about 3’ width and don’t even make a good anchor. Floor model with 4’ bed ain’t much better. ANY MACHINE CAN USE WORK SUPPORTS TO LENGTHEN THE BED The strength, and cut capacity are the main factors and what your decision should be based on.

Dan,

Yeah, I suppose I could’ve been a little more dialed in with the title. Mainly, I was wanting to get people’s opinions on the feasability of 6” floor-standing (not even considering a benchtop) models, but was also hoping it would open up the conversation on alternative approaches different woodworkers use. So for that, I very much appreciate your detailed response. I have considered going without a jointer (I have for this long, but that’s been due to a lack of time in the shop and using mainly plywood and BORG hardwood), and transferring that portion of my budget to a good planer is a definite possibiilty. I’ve seen a few sled designs, but looks like I’ll be looking up some more tonight when I get home.

A jointer is not necessary. There are easy to make planer sleds for flattening, and edge jointing sleds for the table saw for that. The jointer just does it faster. It is far from a necessity.

Planer is a non-negotiable.

I have a 6” craftsman jointer. I don t do a ton of big projects either, but the few times that I have needed it, I REALLY needed the bigger capacity. With that being said, I m waiting for my new Baileigh 16” x 86” jointer/planer combo machine to be delivered later this week. :)

It s almost impossible to buy too big of a jointer. The bigger units (even an 8”) are heavier, which means it s safer to joint large boards / beams by yourself. E.g. my craftsman 6” only weighs maybe 200 to 250lbs and if I m trying to joint an 8ft 4×4, it starts to get a bit tippy as the weight of the whole 4×4 is on the outfeed table. Most 8” jointers are going to be 400-600lbs, and my new 16” sits right around 1000lbs. That makes a big difference in stability and prevents vibration as well.

<sigh> So much envy…

Again, folks, thanks for all the replies. Considering that flattening anything wider than the capacity of whichever jointer I got would require the use of a planer sled anyways, it certainly seems like that’s the way to go. I’m thinking I’ll keep an eye out for the next used Dewalt that shows up. I’ve used a few lunchbox planers in the past, from cheap (Porter Cable) to heavier and more expensive (Makita), but man, the 735 left a nice finish.

Considering that an entire wall of my shop will be bench/cabinet space, edge-jointing fairly long boards with a router and straight edge shouldn’t pose any problems.

On that note, anyone have a suggestion for a preferred planer sled build?

I lied just a little, when someone asks for simple book shelves I do use the Borg S4S Oak or Poplar. But I learned many…many years ago that those boards need to be edge jointed before use or you will have lousy looking shelves.

Have your say...
