I just purchased my first Mill, an HF X2. It is assembled and on my bench, but not trammed. I’m waiting on an order from LMS with a DTI, air cylinder, wiggler and edge finder. While reading Harold Hall’s “Milling, A Complete Course”, and “Lathework, A Complete Course”, I came across the Cylindrical Square. I want to make a few for use with the mill (I also have a 7 x 14 lathe). My question is how do I get two or more to the same length the easiest? Un-chucking to measure would negate the squareness. My idea is to use a carriage stop as a reference. Hall also says to make the cylinders no less than 3 times the T-slot width. Is this real critical? I don’t have steel round that big. And last, in the mill book, the cylinders are used to square a casting of an angle block. The Cylinders are shown secured to the mill table, I assume with studs through the center into T- nuts. Is this correct? Neither book mentions drilling the cylinders for studs. Chuck in E. TN |

Hi Chuck Bogstandard did a thread on making squares you'll find it her. http://madmodder.net/index.php?topic=2175.0 As John showed best to make them from tube that way you have a hole ready made just use what tube you have available. To get them all the same length you'll need a back stop and as you said lock you saddle. Hope this helps Stew |

Thanks for the link, Stew, I'll study that. I have some heavy wall steel pipe (.250") about 1 1/2", will that work? Do I need to make some kind of cupped bush to center the stud? Chuck in E. TN |

Hi Chuck The 1 1/2" pipe sounds OK but don't make the squares over long say 4.5 " max (3* Dia), to clamp them to the table they don't have to be centered on the stud, but the clamp plate needs to locate across the diameter. A good book that shows the use of cylinder squares is from the workshop practice series No 35 :- Milling a complete course ISBN No 1-85486-232-4 Cheers Stew |

As I said in my origional post, that's where I first learned of them. Read Bog' write up to. As soon as it warms up in the garage, I'm going to make several sets. Chuck :hammer: :wave: |
