The rod I ordered arrived today. It is "multipurpose 01 tool steel, tight tolerance rod, .2460 diameter, 3' long, Macmaster Carr Item
8893K202. I purchased 2 3' pieces and with delivery and tax it cost me $19.86.
I could have saved the shipping if I had gone and picked it up myself but it worked out swell as the gentleman that delivered it bought 2 dozen fresh eggs which was a dollar more than the shipping. I live close enough to McMaster that they use a local delivery service instead of one of the big 3.
I know I can get at least 3 mandrels out of each stick and if I watch it close I should be able to get 4. I just hope that the material is strong enough that it won't bend easily and get to shaking.
If anyone lives close to 30122 I'll be glad to share a piece for a visit and idea sharing lesson. I'm still new at this and could use some local hands on advice.
