"Finding the center is challenging"

Isn't that just= a matter of geometry or trig
to find the center ?

I've successfully used acrylic stock from a plastic supplier locally w= ith the appropriate glue. I found that while machining or cutting it I had to be careful not to get it hot. It will mel= t. I used thin sheets for the sides and round stock or a thicker sheet cut = in a rectangle/square for the center. Finding the center is challenging.Regards

Anyway, that hand drill= is what I ended up with. The EBay choices shown by Barry are interesting. Thanks, Barry.

Never-the-less, in past, I had more trouble finding = proper shaped ready-made spools or bobbins to wind a coil. And, if I tried = to construct a rectangular shaped form, I had trouble getting the sandwiche= d parts to stick together! I suppose that I did not have the correct adhesi= ve. I tried several without satisfaction.

If anyone knows the secret= to building a rectangular form, materials & glue, I'd appreciate knowi= ng it.
