Hey, All. So, I picked up a Ryobi AH 115 Planer/Jointer combo unit the other day for $100. This was a complete impulse buy as I have been in the market for a heavier planer for a while. The jointer is just a bonus. It needs a little work and is similar to the old Makita combo units.

The question is… Does anyone know anything about these machines? There’s very little on the interweb that I’ve been able to find.

I have owned one since the mid-late 1980’s and I’m still in love. I’ve made a few modifications for dust collection and it is kind of low but a handmade stand would take care of that. Changing knives couldn’t be easier. It runs true and is easily repaired. I never could understand why it was discontinued.

Looks very similar, in many respects, to the Makita 2030 and Hitachi F1000A combo units of that era… (and all were made in the same country as well).

Ryobi used to be a pro brand and may still
be in Japan. 110v combos of this type
were designed for use on Japanese construction

Ryobi also made a 6” beam planer (I have one)
and a bandsaw that takes a 3” wide resaw blade.

Makita made a little version with an open sided
6” planer that could surface 12” in two passes…
I saw a used one on Craigslist once.

That’s a hell of a machine, especially for a $100.00 bucks.
At one time I owned 8 of these machines and as far as I’m concerned its the best tool Ryobi ever made.
Ill never figure out why they discontinued making them.
I still have 2 of these machines that I use daily, if you need advice about where to get parts let me know.
Since they discontinued them I have gotten pretty crafty in finding what I need.

I have a Ryobi AP-12 thickness planer. I get a lot of snipe and washboard effect on boards. Is there something I need to adjust on it to get rid of most of this or time to move onto something else?

If you machine is old and the feed rollers (both infeed and out feed) have never been replaced, they get hard and brittle and sometimes even a little out of round and they also start slipping just a little. Its hard to notice but its one of the big causes of snipe…. Don’t panic the fixes are easy and not that expensive.

Your post doesn’t say where your from but UPS goes everywhere so it shouldn’t be a big deal.
There is a place in Bend, Oregon called Western Roller ((800) 541-2317) and they can strip and re-coat your rollers with an even better material than the machine came with. Just call them, tell them what you have and they will give you a price. Their absolutely awesome people to deal with, they can do any kind of feed roller like for planners and power feeds.

I get the coating that is semi-soft and it really grips the harder slicker woods like White Hardrock Maple or Northern White Oak and it REALLY grips any softer woods like poplar or anything else.

When you remove the rollers, there will be a square block at the end of each roller. You’ll need to check these blocks, there’s a hole in each one that a spring goes into, and make sure the hole isn’t ovaled out and that the spring is still in good shape. If the blocks have the holes messed up you can’t buy new ones from Ryobi but ANY machine shop can easily make you some. Order at least 1 extra set because with machine shops its all about the set up time !! Once you have new rollers re-installed preferably with new springs but that will depend what kind of shape yours were in, the only other adjustment to eliminate snipe is the rollers that are inserted into the
planner bed itself. They should be set just 1 red cunt hair above the actual bed surface.

Another thing that helps eliminate snipe is when your feeding your material into the machine, give the material a slight bit of upwards pressure, not a bunch, just a little. And then do the same thing as the material exits the machine.

Let me know how it works out for you. at one time I had 8 of these machines, I’ve sold all but 2 to friends and employees and believe it or not every single one of them still works fantastically !!
These are by far the best tool Ryobi ever made.

The only replacement part that takes some due diligence to find is
the field and armature. You have to look in the schematics of older like 1990’s Makita planers cause they used the same armature as Ryobi AH-115. Sorry, I used to have the exact Makita part number written down but I somehow lost the little piece of paper I had it written on. It was always one of those things I wanted to get around to filing in my tool parts folder, but I procrastinated too damn long !! Now I’m gunna have to do the search thing again. Once I come up with the part numbers I’ll post them up on here..

I absolutely love these machines. I love the way they cut and stay true. I love the simplicity of the design and truthfully there just isn’t that many parts that can break that can’t be easily fixed and the fact that you really don’t have to rely on Ryobi to get parts cause if you cant find the replacement part, there easy and inexpensive to have made or you can find similar parts that fit locally.

I’m starting to think about stalking up on knives cause I’m worried they will stop making them soon but I haven’t really looked into the availability lately but from what I’ve been told their still readily available.
I think if they stopped making the knives we would all be in trouble cause they have a lot of notches and slots cut into the knives and would probably be pretty spendy to have to have them fabricated by a machine shop.

Fortunately, with the newer and smarter CNC machines that are out there today it probably wouldn’t be as big of challenge for them as it was 20 years ago, but I still bet it wouldn’t be cheap, It would be the CAD drawing and program design that would cost all the money, cutting the knife would be nothing.. . I guess if that day ever happens, I’ll have to sell them online since I’ll already have the CNC program and all they would have to do is load the machine with a High Speed Steel blank and hit run..

I did have 3 sets of knives done by Farr’s Custom Carbide Cutting in Santa Ana, California, (714-972-1600 ask for Richard Farr and tell him Shaun Ragland referred you and he’ll take good care of you) where they slotted in a good thick piece of solid carbide edge into the stock knives. Ryobi never offered carbide as an option, but man do they they stay sharper longer. I would guess 4 to 1 with HHS vs Carbide, its an amazing difference.

Richard Farr is an amazing talent when it comes to shaper cutter designs, Router Bits, or specialized saw blades for cutting anything special. He is also a sharpening GURU, the guy sharpens anything even spiral cutters for door planers and before I found Richard, I had to throw my dull spiral cutters away and they ain’t cheap !!!.

I was having a really, really hard time cutting white rift oak plywood for a huge cabinet project we did (1.2 million for just fabrication and the delivery and installation was hourly) We tried every blade on the market and everything splintered this plywood to the point that it looked like a dog chewed the cut for us… It was just way too slow to have to tape and razor cut everywhere we needed to crosscut this material. I mean we’re talkin units and units of plywood and thousands of cuts. Richard made me a 12” saw blade that had the thickest steel and the widest carbide teeth I’d ever seen, I think the kirf was a full 3/16th wide but that blade was as smooth as glass. I thought he had lost his friggin mind when I first saw it while picking it up, but when I tried it I was blown away how clean and smooth the cuts were, it was almost as good as sex, but not quite !!!.

Richard also designs and builds his own multi purpose shaper cutters with removable and interchangeable tips that save tons of money cause your investment allows you to do 4 or 5 different stick and cope cuts off one cutter head and their extremely safe and of the highest quality you’ll ever see. The thing that I like about Richard is that if he makes you a shaper cutter, he’ll make sure to get you set up with all the different slot cutters for the different door thickness’s like for interior or exterior doors, even a slot cutter for french glass doors and he also sets you up with all the necessary rub bearings for any radius or elliptical work you may need to do.

If you buy a production cutter, first off its only going to cut one profile and then you have to shop around and piece meal all the slot cutters and bearings before you end up with a workable and complete set. Sometimes its really hard to find the right diameter slot cutters and bearings and you have to do all kinds of extra funky shit to make everything work and that can be a real time killer and a genuine pain in the rectom !!

I’m probably sounding like a salesman but I don’t get anything by referring him, I just like his products and I like to see other people use really good tools. Farr’s Custom Carbide Cutting (Richard Farr) is definitely a number to keep in your little black phone book for that special shaper cutter, router cutter or saw blade you may need some day, I just can’t say enough about Richard and his talent as a blade maker, hes just a really incredibly talented and also a genuinely nice guy.

I’ve got cutters that he made for me in the early 80’s and they are still just as perfect and easy to set up as the day I had him make them for me !!!

Hi Shaun,

Love the post. Inspired me to pick up a local Ryobi-ah115. Got the planer knives sharpened at Farr’s. Farr moved to Placentia.

I don’t have a manual, and there’s no guide for setting the planer blades. Any suggestions?

It is now December of 2017… and at this point in history, I am unable to find planer blades for the AH 115. I am hoping that you or someone else out there can point us to a source for blades!

Hello all,
I bought a fully operational Ryobi AP-125 Planer. It looks just like the AH-115 above without the jointer on it. Does anyone have sources for an owners manual and replacement knives? This post is the most recent I could find anywhere on the internet. Any hints on tuning and setting the knives? I may just have to sharpen and run the knives it has.

I know the Ryobi AH-115 inside and out and although they are discontinued, parts are still available. During that time period there were 3 planer/jointer combo units made, Makita, Hitachi and Ryobi all made their own version of the units but ironically, they were all made under the very same roof. Many of the parts are interchangeable especially internal parts, belts and knives.

I’m not familiar with the AP model although I think I’ve seen them. Check for similar versions thru Makita and Hitachi. As far as the knives go, I’m not sure about the AP but the AH version has the knives screwed into a blade holder and then bolted onto the cutter head with 8 bolts after the knives have been set to the correct cutting depth using the provided knife setting jig. I’m guessing you don’t have that jig with the machine ??

If the AP knives are first held in a knife holder and then bolted to the cutter head, you can remove the knife holder without loosening the knife and a machine shop can make you a setting jig out of a piece of aluminum fairly cheaply. Another way would be to measure from the lip of the knife holder to the sharp edge of the knife before you remove it from the knife holder to be re-sharpened. After re-sharpening you’ll have to reset to that measurement, it will take more time to get it right but it can be done.

Hope this helps,

Wow, thanks for the quick response and suggestions and greetings from Maine. Given the similar appearance of the AH-115 planer portion to the AP-125 planer I would say they are the same unit except that one has the jointer option installed. the knives are 12.5” long, 1.25” wide and .125 thick with 8 bolt holes for the blade holder. Holes #2 and #7 are actually slots cut through the back of the blade. the reason for that is not apparent. There are 2 smaller holes that screw the blade to the blade holder and they are of course elongated slots to facilitate setting the knives. Do you have a source for the AH-115 knives that you can point me to? Do you have a source for operators manual for either of these machines?

Thanks in advance.

I found these on Amazon, they are 12” not 12.5” but the hole pattern looks about right.

For use with Hitachi Planer/Jointer (no.P12R and no.P12RA). Is that the machine I need to look for and are these the blades that fit the Ryobi AH-115? I can’t find any information on the Makita.

thanks again.

I was just digging around in my spare parts box for my Ryobi and thought that some folks might want to have digital copies of the parts list and manual.
