Uneven thickness when planning

When planning 8' boards, there is a difference of 40/1000 inch between one side of the board to the other side in thickness. No apparent adjustment on the planner. It is a Ryobi 10 inch.

Surely you have some mounting screws for the Knives, don't you? You may have to loosen those and Re-set your Cutter Depth & Level. I use a "Step-Gauge" to do that with. In some Rare Cases you may have to shim to attain the desired results.

My Jet Molder/Planer cuts the last four inches of the piece slightly thinner. The piece is straight and fully supported on the table. The feed rollers seem evenly adjusted. What's up?

The problem you are describing is called "snipe" and it can be caused by alot of different things. Even the best woodworkers have to fight this problem.
- you did the right thing by making sure that the matrial is supported, but if the oppisite side of the board is'nt true it will carry over onto the face. The only way to "true" a board is to use a jointer.
-when jointing a board you only want to do one side(face or back) and one edge,then it is ready for the planner.

-Now for solutions other than jointing-
1) Make sure that the infeed table and bed plate are clean, and wax or lube so that the board moves freely.
2) Try taking a lighter cut.
3) try a different piece of wood to see if it is only affecting that material (wood that is bowed is more likely to snipe) If it is bowed try feeding the material with the bow down..
4) make sure material is supported
Also your machine may have a bedplate adjustment to help with snipe you will have to look at the manual to find out.
If you take a close look at your machine you will notice that the length of the snipe is also the distance from your rollers to your knives, This means that the board is not laying flat and is being pushed up into the head until it can be supported by the next feed roll.

I hope this helps

The planner nips the end of the board

My planer does the same thing.

1) I don't make the final cuts on my boards until after planing.

2) I discovered why the planer does this. I don't have a planer table. I use the two metal stands that came with the planer, and they don't really hold the board flat & steady like a planer table would. The planer has 2 rollers >>> one roller is on the feed-end and one roller is on the finished-end. When the end of the board goes past the feed-end roller, it is no longer held flat by two rollers. The weight of the board causes the board to tip up into the planer blade on the last 3 inches. So sometimes I just hold up the end of the board as it finishes ... but it still takes a nip out of the board now and then.

Up-vote if the information helped you. Thanks for the feedback.

Where do i find a belt for ryobi 18v planer model cpl 180

If you have the remnants of the old belt, take it to a well stocked hardware or auto parts store. If the belt is missing, you will need to measure the width of the outer 'V' on either pulley, the diameters of both pulleys, and the distance from shaft center to shaft center. The folks at the store can compute the proper belt width and length from that. Be sure to set the motor position so that there is about 3/8 to 1/2 inch deflection of the belt at mid-point and that the two pulleys are in the same vertical plane. This will greatly increase the belt life. Hope this helps!

Planed board has a lower step than the rest of the board after passing thru planer , not equal amount planed off.

I think you are talking about what is commonly called "snipe". This is an inherent problem with all planers, but especially with heavier cuts. You can take lighter cuts, or you can start with a board longer than your intended finish length. You can also put the board you are planing on top of a longer board, then feeding them through together.

Uneaven thickness when planing. how do i adjust

You mean you're getting speed bumps? Do you have the blade setting tools that came with the planer? You need them, it will be hard to do without them. It is a little C shaped jig that rides on the drum over the knife, you have your knife sharpened and set in the drum, snug, not tight,under the knife are adj screws, you run the knife setter around the drum and just scrap the top of the knife, do not pull the knife, just go over it barely scraping it, then snug it up, do not tighten anything yet, move on to the next screw, do the same thing, then the last screw, then go back to the first, still good? second, third, now, tighten them up, the setter doesn't pull the knife, just barely scrapes it, but it does hit it. Now do the other side. Both knives will be set the same, no more speed bumps, or uneven cuts. To move the knife back in, if you brought it out too far, use a block of wood to tap it down, make sure you put the elevation screw down first. Do not answer the fone while doing this. It is serious stuff, when those knives start flying. Hope this helps.

The knives on my Delta jointer don't contact the trailing edge of the board. As a result the board has a convex edge (high in the middle) The tables are parallel and the outfeed table is flush with the...

The knives could be dull, you would have to be the judge of that. If the bevel & face are rusty they are probably dull. They can be honed or taken to a sharpening shop.

The outfeed table could also be too high. I usually adjust the knives above the outfeed table. I use an aluminum straight edge & adjust them using a sheet of printer paper on the outfeed table so that they are about the thickness of the paper above the table. I place the paper on the outfeed table put the straightedge on the paper & rotate & adjust each knife so they just slightly hit the straightedge when I rotate the cutterhead by hand. Needless to say the jointer needs to be unplugged while doing this.

The board could also be convex to start with. To fix that problerm start jointing at the start of the convex part and not at the end of the board.

Good luck,

How do I change the drive belt? On a Ridgid 13" thickness planer model TP1300.

You need to remove the right side cover, indicut knob, crank, and cutterlock knob. Remove the top cap (4 screws) crank the motor asssembly to the top exposing two hidden screws in side wall, remove those and the two at the top and remove sidewall. . Tension adjustemnt screw is right near the motor pulley. Loosen it and push motor inward while sliding belt over pulleys. It is a little tough getting the belt in between the pulley and main carriage. If you attempt to put the belt on one pulley at a time, you are working a diagonal, which is longer that the inline dimension. Apply a drop of liquid dish detergent to each pulley for lubrication. Start the edge of the belt onto both pulleys; making sure the splines & grooves are aligned on both pulleys. Slowly work the belt on, 32nd of an inch at a time one pulley, then the other. Wash the soap off when you are done'

Blades won't engage on my ryobi planer

It can be fixed....I assume when you say the blades won't engage that the motor does come up to speed.
It's been years and years since I took one apart, I think they have a newer model out now
At any rate, there's a drive belt on one side and a chain on the other. You could have broken a link in the chain. You might have burned the belt..
You're going to have to start pulling covers off and take a look. If you're not mechanically inclined, there are usually small tool repair shops associated with most major metro areas that have factory certified techs who can do the repairs for you.
If you are handy, and feel up to it, here's a link to a site that will help you find parts and see diagrams of its innards.
Good luck, and I hope this advice proves remotely helpful..
If so, please take just a moment and rate this posting...thanks.

Jointer Usage

A jointer has 2 uses. 1. it is used to make the edges of boards straight. If you look down the edge of any board, you will see that they are not straight. This is called a crown. by feeding the board threw the jointer, you will take the high ends down to make the board straight. This is necessary, excuse the spelling, for glue ups. 2. It is also used to flatten out a board. Same as the edge, the face could have a cup. By sending the face through the machine, this will make the board flat. Then you send it through the thickness planer to make the board symetrically even. You can use the jointer to make rabbets also, but there are other machine that will do the job better and faster, such as a router or a table saw, with or with out a dado blade.
