Crossdrilling block for lathe

Thought it was such a cool but simple tool that I just had to have one. So here is mine. Used some 2" square aluminum stock and then faced it on the lathe on 3 sides (left the other 3 alone). Mounted it on the compound in place of the tool post and made a groove in it with a 90 degree drill mill. Nice thing is that it is centered on the spindle without any effort. Then drilled 4 holes to use to clamp the round stock in the jig. I went with bolts rather than studs so I can work closer to the collet. So there it is; dirt simple but very useful.

Full credit to Foozer for the great idea.

Frank Ford posted on the Home Shop Machinist forum about his simple radius dresser:

Coincidentally, I just this week made a radius dresser for my tiny Sanford surface grinder. I just used materials I had on hand, and didn't make drawings. I'm at work now, but I'll post a photo or two here when I get home tonight.

Update, tonight -

Here it is "in situ," on the mag chuck:


I had this welded angle with a big hex nut stuck on, and I used it as the basic support. Just another item from the salvage bin. I bored the nut and angle to 1.125" to insert a couple of standard ball bearings that could accommodate a half inch shaft.



The "arm" of the dresser started out as a piece of heavy hot-rolled angle.



I turned and knurled the entire shaft from a piece of 1.5" 12L14 steel I had in the bin, and made a little flat spot to be able to lock it in place at exactly vertical so I could use the rig as a standard flat dresser as well as swinging it for radius forms. I did the graduations mostly because I could, and I can always use the practice, dontcha know.



Once I was finished, I spent some time with a height gauge and measured the center height accurately. As you can see, I wasn't so concerned with neatness as when I stamped the graduations on the knob. Oh, well, I never really expected to photograph this one. . .
