Topic tags/keywords: help woodturning truing question tip

Hey

I recently got some wood for free from a friend but they are not completely true on each side. If looking at the endgrain the profile looks more like a skewed parallelogram without a 90 degree edge/ corner. Do i just run these through a planer and or jointer? How would I go about truing these up ?

The image i posted is the worst one (or the one where you can see what I am dealing with). All i want it to true up these blocks. Im new so please forgive the question if its a simple one.

Thanks

I wouldn’t mess with a jointer or planer … I would just run them through a tablesaw to get them approximately square. If you are going to turn them, they don’t need to be square or true.

+1 to what TheDane said
if your turning it it does not have to be square

What are you trying to turn?

I would just mount it on the lathe with drive and live center and use my roughing gouge to see what it looks like round.

When I use a froe to split firewood into spindle blanks, they are no where near square or round. I mount the piece on the lathe between centers, eyeball close is close enough. It’ll be on center as soon as it is round.

You could draw lines from corner to corner. Where they cross is the center. On a square it would be accurate, on the piece you pictured it will be close to center.

The only reason I suggested trimming down on a tablesaw is to eliminate some of the ka-chunk-ka-chunk action roughing on the lathe.

Plus, depending on the stock and project at hand, the waste you trim off could be useful for something else … that’s where I get a lot of the pen blanks I use for my Freedom Pens.
