I saw this piece of scrap brass at the scrap yard 6 months ago and instantly saw a finished part in it, must have come from a steam plant as it is cast brass and painted Kentucky chrome.
I then turned the neck true, bored and threaded the inside. Rigged a setup for turning a nice radius for transition to facing the flange.,
All done, Sorry for the blur,
Turned it over and faced the the bottom.
Drilled and pipe tapped an intersection hole, band sawed the extra off and sanded smooth on both edges with my 30" master sander.,i
I bought these SPAX lag bolts at Menards, trued up the flange and threaded 32 TPI bastard OD. Made 4 custom acorn nuts and polished the brass including the hex flats on a hard felt wheel.
Cut the other two sides off on the band saw and then milled all 4 sides with a 14 degree patternmaker end mill and polished, drilled 4 mounting holes to the minor diameter of the SPAX lag bolts and then threaded the holes with an extra SPAX bolt and a Milwaukee electric impact wrench.,
Cleaned up the steam dinger, painted the gong.,
Mounted all up with hydraulic thread sealant to a 15 inch cast steel locomotive switched bell.,d
Don't comment about safety procedures, it all worked, the plastic pipe and a few boards held the weight of the bell while getting the 4 lag bolts started in the pre tapped holes.,o
All done, Acorn nuts look great, note the 3/8 brass tubing supply line to the bell. Several jigs were made to drill and tap the mounting holes good and square, another jig to drill the 3/8 supply line thru the shingles-3/4 plywood and 6 inch red oak post holding up the ridge pole, I then knurled a 3/8 SS rod and reamed the hole out to .381 so the tubing would slip in easily with no clearance. I now have a door bell that can be heard anywhere on the property when someone comes to visit.
