I've tapped my 1275 block, all the waterway holes, with the goal of using the three front studs and dry decking the block.My question is - what material should I use for where the new threaded stud holes overlap original block and "filler" material? My feeling is brass might cut similarly to cast, enough not to affect the machining anyway?

From memory (and I would have to check the notes I made from when I did it) I used EN1A bright mild round bar and threaded it with a 3/8 unc split die to get a nice “fitted” thread in the stud holes.

Use cast iron bar, why mix two different materials unnecessarily? |

Hmmm, why - because threading and screwing cast iron bar in is new territory for me, but appreciate it would be preffered. |

I wouldn’t be deterred by it, it’s free cutting and easy to work with.

I used low grade steel bolts but use a 2-flute mill to ‘drill’ the hole and the same chucking to tap the hole. On 17th Nov, 2014 Tom Fenton said:
