Core Profiler

[ggardner90]

so i am going to warn you i am really pissed right now.

i have spent the better part of 20 hours building and thinking about this core profiler. i started to assemble it after i had built 3D models in Solidworks, spent nights without sleeping lying in bed thinking about how it was going to come together.

I am now at wits end and almost want to smash the whole F***ing thing. some how i am off by about 2mm on the supports so that the supports i have made probably wont work.

does anyone have any ideas on what i should do?????????
or stories to make me feel like less of an idiot????????

Did you make a planer crib or a router bridge? There's lots of ways to f'up every step along the way. post some pics and more details on what an dhow you made it.

Post some pics
If your supports are 2mm too short you could contact cement tip spacer to them. Would turn out pretty close.

i will post some pics

drank a couple beers, watched some TV and i am now read to work on this, again. how do you guys get wood to be precise and is it necessary to have a jointer when making the planer crib because my planer seems to be slightly inaccurate +/- 1mm across a board the size of the crib but not in a repeatable way.

great idea about the tip spacer by the way.

There is a difference on the order of millimeters across the width??? Maybe you need new blades, or to adjust them. That's too much error laterally. Are you actually trying to read numbers on a scale on the planer and using that to judge how much to cut off? Cause that will never get you close. You just need to do lots of passes, without lowering the planer at all,, and slowly shave off tiny amounts until it is spot on. No jointer necessary.

This is good, gotta get you used to failure and frustration early on so you can build up a thick hide of patience. This won't be the first hurdle .

the planer we had was about a .5mm off laterally so we rough passed them there and take them to an industrial sander to finish them up.
I then found I should just do one core at a time, still not as accurate as was needed.

You don't have to have a joiner. And beware of the joiner. They flatten 1 side and it's not in relation to another side of the board. I had a problem using a joiner that was off by .5 mm from 1 side of the table to the other. After a 1/2 dozen passes I had myself a wedge. It's posted in the forum if you want more details about joiners. If you have an expensive parallelogram joiner you can get flat boards on all sides and square to each surface of the board.

Once you know the limits of your power tools you can start working within their limits and make adjustments, or by better tools. It's all part of the process.
