DIY Expanding Hone

But for something like an engine cylinder bore, the between centres bar is the way to go, and even after boring it to a few tenths under size I will make an expanding hone/lap to finally finish it to size (I DO NOT mean those three legged glaze buster contraptions).

Hey Phil,

Is your diy honing tool written up in another thread somewhere please ? Or is there a book or website I could look at ?

I have used a piece of wooden dowel with metal polish on it – that seemed to work ok on the very small amd simple things I have built so far, but I'd be keen to learn about how you experienced people make hones for cylinders.

You could do worse than have a look on MEM at Ramon,s post on lapping and honing.
