| Ginger Nut:
I am on making V-blocks the block is 55x65x140L I will cut into two. I have already marked out everything drilled at the bottom of both V's and milled out the clamp slots on the sides. The ML7 vertical mill is a great attachment as are my hold down clamps. I am cutting two V's one large one small. Large will be approx 1" deep, small approx 1/2 deep. My dill-ema is in doing the V's. In all my web searches on making V-blocks each one I find has either another set of V-blocks to set the angles with for milling or an inclination/angled vice. To do this without using the above I have so far come up with. 1 Hand cut rough the V then mill on the ML7 to finish 2 Use the 4x6 BS in vertical mod again rough cut and mill I still need a way to mount and clamp the block on the lathe to mill it. Any suggestions |

Either turn the virtical slide to 45 degrees or clamp the block in a vice at 45 , and use an end mill . |

Have look at Harold Halls web site , |
| SwarfnStuff:
Harold Hall's method will work, his books are a great source of helpful info. At a pinch, if you can mill your hold down slots by holding in the vise first, these can then be used to clamp the block to the table. Then, If you can mill a slot (Say 3 or 4mm) to the depth you want your vee it is possible to use a woodworking carbide edged 45 deg Vee cutter to cut the groove. This must be in very gradual increases of depth with lubricant. Of course you may prefer to get a milling vee cutter. But if you already have the woodworking cutter It will work. At least in my opinion. -- I have used woodworking bits in the past but admittedly only in aluminium. So something for you to think about. John B |

It would be nice to have a some sort of template. How accurate you need? Just for fun/looks_ http://www.craftsmanspace.com/sites/default/files/free-knowledge-articles/steel_square_layout_45.jpg Or 3-4-5 formula and then establish 45 degree within this triangle once you have a square. You need a method of checking accuracy, if you want any decree of certainty. Therefore I bought mine V-bloks, because they are used fairly often. There are some disc/button or template/pin methods that will allow you to verify by measurement that you are reaching the accuracy for setup like using a sine bar without sinebar. I tried to google it, but didn't figure out correct catchphrase. Pekka |
