|Bridgeport T Nuts|
|Bridgeport you say? Well, I might have gone out and bought a 1973 Bridgeport. Ooops. One of the first project on the mill was to make some T Nuts. I have a hold down set for the Shoptask that is 3/8" but I think normal size for the BP is 5/16"...so I set about making a set of 3/8" T-Nuts.|
|First op was to get a chunk of steel squared up and hit it with the face mill. I love face mills!|
|Nice finish. Endmills are lame for this sort of thing.|
|I measured the height I would need...|
|...and proceeded to whack the top off. I have enough material to make 5 pieces out of this one blank.|
Yep, chamfers are nice.
I cut the steps with a 3/4" Seco indexable mill that had a bit of corner radius.
|I used this setup to true up one side on each nut. Note that I clamped two pieces in order to even out the pressure on the jaws.|
|To get them all the same length I gang milled them down with a face mill.|
|Just need to drill and tap. I set up my indicator base as a work stop and used my LC/EF to indicate in the first part. After that, just rinse and repeat.|
