I’m new to serious woodworking and to the LJ Forum. I recently demoed a Makita 2030N Planer/Jointer combo unit that I’m considering buying. The jointer seemed to work okay, but left a little deeper cut at the end – kinda snipe-like. I figure this is likely just a need to adjust the feed tables to get them totally flat. (I was using a fairly short board too – approx. 18 in., so that may have had something to do with it. Or, it could just have been my inexperience with these kinds of machines.)

The Planer was a bit more perplexing. The knives seemed sharp and in good shape, but when I passed the same 18” piece of black walnut through it left noticeable grooves on the surface. When I fed it into the planer I had it placed firmly against the side of the bed, but when the rollers picked up the piece it made the board go in at an angle.

I’m really new to these machines, but my understanding was that a surface planer was supposed to leave a “baby bottom” smooth finish and no grooves. Are the grooves possibly a roller issue? I haven’t had a chance to get a good look at the rollers, but the seller said he had it gone over by a professional used tool store and they gave the rollers a clean bill of health.

Any thoughts?

if you have grooves then there are chips or places on your knife blades that have hit metal…they will have to be taken out and re sharpened…snipe is common in these machines…unless you have an extended in feed and out feed table you will probably always have snipe…you can adjust your rollers to make it minimal but you will still probably get some snipe…yes your boards coming out should be very smooth…your knives are the one that control that…and the fact that your board twisted to one side going in..usually means your knives are dull and need to be resharpened…i hope i could help you some…grizzman

Metal for sure, Paint and even glue (jointing edge of plywood) will dull or chip your blades ! I have older jointer that I use only for used lumber and plywood. My bigger jointer is strickly for NEW SOLID Stock.

Grizzman is correct. I was getting ridges in my boards and they would go in at an angle also. I replaced the blades and they go in straight and come out very smooth.

When you use the jointer you may be pushing down on the end as it runs over the blade. This could be causing the deeper cut at the end. Try pushing down on the outfeed side once it has passed the blades and see if it gets better.

I agree with Cannadianchips. I have an older Delta planer for the rough planing (sic), and a Craftsman for the finishing. This works well for me. The most critical part of the process depends on the heigth of the tables. My table is about 1/16” higher at the end of the outfeed table portion of my setup. I think conditions you describe would be eliminated with a longer infeed and even longer out feed table. Both my planers are built into one table, 48” wide and 84” long. The infeed is 18” from the end which leaves about 54” of outfeed. The planers are at opposite ends of the table, with a space of about 20” between them. The only draw back is when running the planers, the material removed from the boards is blown toward the other unit.

I think your’re correct on the snipe issue, just make sure the infeed AND the outfeed tables are adjustable. Grooves in the planed wood are most likely caused by a nick in the blades. You could raise the outfeed roller, run a piece through and isolate the problem at the knives.

The uneven pulling is something I experienced on a older Delta 13” planer. The pressure on the infeed and outfeed rollers is often set with an allen bolt compressing springs at either end of the roller shaft. If these are not set correctly (evenly) it can cause uneven pressure contributing to pulling to one side.

As a minimum I suggest you insist everything operates to your liking before even considering purchasing it. If the seller can’t make it right, you will have an even more difficult time. And if you want more advice ..o0.. I’d pass on the thing altogether and look at 2 machines, a jointer and a benchtop planer. Here are my reasons:

When and if the motor fails you are left trying to get parts for a machine-specific discontinued product. Then both planer and jointer are out of commission. That would be a total pisser…

It’s hard to get excited about a 2 knife cutterhead. Most planers are 3 or 4. Makes me wonder if that is contributing to the surface finish problem you identified

You will want an 8” jointer at some point. Just like we all want FAS cherry at $1.50 a BF. It’s just natural…

How comfortable is the working height of the combo machine? I recall it was kinda close to the ground…

Resale (if the hobby is not your thing) is much easier with seperate machines.

You didn’t talk about price but there are lots of good deals on 2nd hand seperate machines. Good luck with your decision…and a shout-out to all the combo machine members!

The grooves in the finished board and uneven feeding have been well covered here. As for the snipe in the end of the board when jointing, it sounds like the outfeed table is a little too low. It should be exactly in line with the knives when they are at top dead center of their swing. With the outfeed table too low, as the end of the board clears the end of the infeed table, it drops down onto the knives, limited by the cutterhead. Check the machine and make sure there is a way to adjust the outfeed table height of the jointer. If not, you’ll never be able to eliminate that snipe. Also, check and make sure new knives are available for the machine. Good luck.

Great thoughts and insights. Thanks so much! I’m still looking this machine over carefully and giving it some thought. If I do decide to move forward w/it, I will likely make a lower offer than the asking price to account for some of the work that would have to be done to bring it up to a workable standard.

Thanks again!

I have this same plainer/jionter and have had it since 1985. I have run thousands of board feet of lumber through it. It will not always have snipe issues. I can get mine to snipe if I don’t adjust it correctly or let the knives get dull. There is no adjustmeit on the outfeed table for the jointer. There is no need for any. You adjust your knife hight to the outfeed table. Adjust your infeed table coplainer to the outfield table. The only time you need adjustments on the outfeed table of a jointer is if there is no way to adjust hight and level of your knives. I purchased one extra set of HSS blades and a Makita wet stone knife sharpener for mine and it will be a long time before I need to buy any more knives. I did replace my rollers about twelve years ago.

Not sure if I agree with Oluf on the outfeed table adjustment. Here is something to consider…

I’m going to chime in on this dead thread: Oluf is 100% correct. The out feed table in this model is static. You must adjust the knife depth. The knife is rather long on the jointer and has a lot of play for adjustments.
