- - - Find Your Center - - -

I was inspired to make a Center Finder as I did not want to drive 20 miles or pay extra bucks for a store-bought model.  

Upon doing a search, I found https://www.instructables.com/id/Make-a-Center-Finder/  posted by Phil B.

I just like to minimize my time working with metal, so I built a drawing, used MDF (can you imagine?) and cut the pieces out at TechShop in San Jose - www.techshop.ws.

Above, you see what the completed finder looks like...

... and cut it!  Here's the Corel Draw file...


... and here's the 1/4" MDF after cutting...

This (fuzzy) pic shows a spline on top of the two pieces.  The splines get glued-in to the top and bottom "ELLs".  They assure alignment and connectify the whole thing together.  That's right - I said connectify.

It's altogether now. (All Together Now!)

Now we get down to business.

This Center Finder will work with round pieces up to 5" in diameter.  The drawing could easily be tweaked to enable larger Center-Finding.

Mark a line along the 45 degree bar.   The ELL without the 45 degree bar is on the bottom, and I placed the Center Finder on the round piece.

Rotate the piece and run another line across the first line...

The lines will intersect in the middle of the round piece.

If you're a 5" piece (or smaller) piece of wood or other material...


Cheers!
