One of these popped up on craigslist today and I was thinking of taking a look at it after work today. The guy is asking $400. It includes the planer, stand and mobile base. He said the knives need to be sharpened, so I take that as they probably need to be replaced as he said they’ve been sharpened previously and I don’t know how many times they can be sharpened. It has some minor surface rust, but he said he used a 220 emery cloth on part of it and it it took the rust right off.

From looking at previous threads, I gather that there’s a knife setting jig, but I looked at some parts websites and didn’t see that listed, so I’m unsure if that’s something that should come with the planer or a 3rd party item. Any info there? Also, if I have a oneway multi gauge, would that work for setting the knives or is it too large to get where it needs to get?

The planer has what look like particle board in/out feed tables (not the steel rollers). Is one better or worse than the other? Is there any reason why this wouldn’t be desirable?

He said it has a 4.5” dust port with a 4.5 to 4” adapter he bought from rockler, but he said it doesn’t exactly fit 4” flex hose. Any idea if there is a different adapter out there that would fit 4” flex?

Other than testing all the adjustments, making sure the two speeds work and running some boards through it, is there anything else I should look at before making him an offer? Oh, and speaking of, any thoughts on the fairness of the price? I figure I’ll take the cost of replacement knives and subtract that from his asking price and offer him that? Am I on track there?

Price seems decent if it is in good shape. Not sure of specific things to look at on this model, but look for general excessive wear, slop in the bed raising mechanism, and sound/vibration when it runs. I would run a pretty wide board through it and check it for evenness of cut by measuring thickness from side to side. Also check for snipe produced on the leading and trailing edge.

On the dust port, I wouldn’t worry about that at all. It is always possible to convert one way or the other. 4.5” to 4” shouldn’t be difficult. You might need to make something to convert to a standard 4” dust port first, then attach your flex pipe to that. Could be something as simple as this: picture 4 pieces of 6” x 6” x 3/4” MDF. Cut a 4.5” hole in three of the pieces, glue them together into a sandwich, and slide onto the 4.5” dust port. Then cut a 4” hole in the 4the piece. In the 4th piece, mount a short section of 4” PVC pipe using construction adhesive. That is your new dust port. Then screw the new port to the MDF sandwich adapter/converter, attach the flex tube to that, and you are suckin’ dust. That is a worst case scenario if you can’t find a simple adapter, or replacement port.

Thanks for the info. It seemed to be in pretty good condition so I ended up buying it. The spec sheet is not lying when it says it weighs 488 lbs. It was pretty easy to lift into the bed of an f150 with 4 guys, but getting it back out with only three took about 30 minutes of head scratching.

You raise a good point about running a wide board through it. Unfortunately I didn’t think of that and only ran about a 6” wide board that I had previously jointed flat on one face. One of the knives must have a knick in it because the planed side of the board has a line all the way down, but I was planning on replacing knives anyway, so that wasn’t a big deal.

It did come with the knife setting jig, but I haven’t had a chance to download the manual to read about replacing the knives yet, hopefully it is not too bad.

There are some areas where the paint is scuffed, so I am thinking about repainting it. It looks like Delta sells OEM paint although it is pretty expensive, but I found some good info online about the formulas you can take to Sherwin Williams to get an exact match.

the knick in the blade is no big deal, even if you are planning to replace the knives. If they are not dull, you can just slide one blade a slight bit to one side and it will make the ridge go away by offsetting the knicks. I don’t mess with touching up paint on tools, but yes, easy enough to get a custom match.

Paul, that is a good suggestion about sliding a knife to one side or the other to fix the knick problem. I had seen that recommended before but had forgotten about it. I am not sure how to tell how sharp the knives are. What I do know is that the finish on planed boards is not as smooth as boards I run through my DW735. Does that indicate dull knives? I assume it does.

Also, not sure if it is best to post here or start another thread, but I have seen prices ranging from about $45 all the way up to $200 for what look to be the same thing – HSS knives. At this point I don’t want to put the money into a spiral cutterhead or carbide knives, but once I verify this machine checks out and I sell my DW735, I plan to look into one or the other a bit further. I am not sure if it would be worth the money yet as my planer gets used maybe 2-3 hours a year.

These knives on Amazon say they are for the DC-380 planer:

However if I scroll down it says they fit the 22-677 and I have a 22-675. When I searched for 22-677 on Google, I didn’t come up with much except replacement knives, so I’m wondering if 22-677 is actually the part number for the replacement knives for a 22-675 planer.

At any rate, I would appreciate any feedback anybody has about these knives and whether or not they will fit.

Also, I know I can probably find a bunch of info on this by searching (haven’t had a chance yet), but since I’m asking questions I’ll go ahead and ask…as far as sharpening planer knives, is there a rule of thumb as far how many times you can do it before they need to be replaced? I know the knives in the planer have already been sharpened once. There is a sharpening place about 15 minutes from my house, so it probably wouldn’t be too bad to get them sharpened, but from what I’ve seen online, it’s probably easier to spend the money to replace the knives vs taking a chance on having to change them twice if for some reason the sharpening job doesn’t fix the problem I am having with the planed wood not being as smooth as I would like.

Global Tooling carries a set of knives for the Delta 22-677 for $54.

What you probably have to do is get the measurement of the knife blades for your planer and match to that.

I would suspect that even if Delta had made a 22-677 planer and a 22-675 that whatever the model differences the planer blade specs would probably be the same.

The best knives I bought for mine were branded “Titan” and I got them from Holbren’s for $45 (as I recall, this was quite a few years ago). Sharpening costs can vary from 50ยข to $1.00 an inch for the cutting edge, so check before you leap. Mine is a 22-680 (bought 11 years ago) and it has the rollers for infeed/ outfeed…I seriously doubt they are superior to to the melamine that was on the earlier models. Don’t get wrapped up in the various model numbers, a Delta 15” is essentially the same planer regardless….the model numbers seem to indicate minor changes like the infeed/outfeed, color of the paint, and other such stuff. Changing and adjusting those knives isn’t that hard…remember to tilt the motor forward. BTW, I think you got a very good deal; congrats.
