I finally wired up my Grizzly G0453PX 15” planer today. This was the first use of a planer ever. It produced a lot better finish than i ever expected, but I really dont know how to uset it…
Today, I needed to make a repair to a cabinet and needed a plane a piece of wood down to a certain thickness. it was difficult for me to get the exact thickness. is there an easy way to do this other than a lot of trial and error?

Im used to my Incra table saw fence where I can just set it and rip it and its perfect every time…

Thanks

There must be a scale on it somewhere… with an indicator on the table telling you what thickness its set at.

yes it has a scale, but i wanted it to be more accurate than eyeing the scale. I dont think its possible to eyeball the scale and get it within a 64th? and really want it to be a lot closer than that. Maybe a Wixey digital scale is the answer?

when i am doing repeat work

i find which setting is closest
and keep track of the handle position
some planers are 1/8” full turn
some 1/16”
i keep the handle to the same place
(if on top then towards me or away)

if on the side
then up or down
each 1/4 turn is for fine settings
(or 1/8 turn)

that way i can come back to the same place
if i need to move it for other stock

for custom you have to go by measure
till you get it right

i use a block that is the one i want to replicate
and lay them together and feel the differences

If I am planing a piece down to 3/4”, I would set my planer scale to 3/4 and plane all of the pieces at one time to the scaled 3/4 inch and accept the scale. I have a stop on my planer for various thicknesses. If I am trying to match it to something else, and as I get close to that dimension I start to use a calipers to verify the accuracy. If the piece I am comparing it to is a free piece and not glued to something I will lay the two pieces next to each other on a flat surface to compare thickness after each pass as I carefully plane it to the final thickness.

At least I see that I was not totally going abou it wrong. I was having to take a little at a time until I got to the right thickness. I did figure out that turn is about a perfect 1/16 and this helps a lot. I guess the first pass I just need to make sure I am too big rather than too small. DAH…
Has anyone installed a Wixey scale on their planer? I have to use technology to make up for the lack of skill.

I know there are some digital scales available for some planers. Might be Wixey. I’ve never used one, but they should get within the tolerance you want.

Don’t know if it will work on your planer but if I know if I have to return to a setting later on in a project, I just draw a line in the dust on the cutter hood to index the position of the handle.
Best thing you can do though is plane all your timber that’s required to be a certain thickness at the same time.
Get a feel for your machine, If one rotation of the handle is an 1/8 inch of a cut, a quarter turn will be 1/32, an 1/8th of a turn will be 1/64 etc.

I have a Wixey on my 0453. You have to manufacture your own mounting. I think they were originally made for the table top planers. Mine works very well, but I will usually back it up with a set of digital calipers, if I’m trying to repeat or duplicate a thickness.

When planing I always have my 6 inch calipers in my back pocket when planing. Just keep checking. Snowy River has it right.

I have the Wixey on my DW745 planer and it works very well.

There have been several times when I had to plane another board to exact thickness. It has a caliper setting that allows you to measure the thickness of a board and then I just plane down to that thickness.

Otherwise I do as Wayne and plane all my boards at the same time. With the Wixey I often don’t have to turn the planer off between boards as I can just watch the digital display as I crank down for each pass on the boards. Saves a bit of time.

I also have a Wixey on my DeWalt 733. 95% of the time I do not use it. However, when I do need it, it is great to have. If I think I may need to come back and repeat a particular thickness on a piece, but I need to set the planner at other thicknesses in the interim, the Wixey is great.

^I’ve done what Patron and the others do. I’ll put a piece of blue painter’s tape on my depth gauge as a “target”, then ease up to it. I’ve got a digital meter too and I’ll usually zero it on the desired cut, then sneak up on it. Why? It’s because I’ve forgotten the target thickness before, lol. I can’t rightly forget zero:)

Take the time to calibrate the index scale on your planer. That will get you into the ballpark. Mine is surprisingly accurate, but I rarely can cut directly to the finished thickness. It usually take several passes.

I do like others do and note the handle position for the depth adjustment. I almost always stop the handle at the quarter turns, which handily stops every 1/32” of thickness.

If you need to be VERY precise, you should sneek up to your line on a test piece then run your entire batch of boards.

Many thanks for all the help. I don’t think its going to be as difficult as I first thought as long as I go about it the right way. I cannot believe how good the finished product looks. The spiral cutter makes a great finish. The only thing I noticed is that on the softer wood you can see the pattern of the outfeed roller. I was going to loosen the tension on the outfeed roller, but a little sanding is all it took to make it disappear.
