[modeleng] Re: Myford belt pulleys

Hi David

I am using a lot of cast iron in the construction of my little lathe (and 
producig masses of swarf and black carbon!)

I buy this material from College Engineering.   Their web site 
www.collegeengineering.co.uk lists all of their material and prices.   The 
cast iron is continuously cast and a joy to machine.

I also wish to use polyvee belts on my little lathe.   I should be obliged 
if you would give me the number of the ME issue containing this Hemingway 
article.
Thanks for your help.

Cheers!   Hubert
