Default pulling a dimple

Okay so I've read the entire "soldering ss" thread and I'm ready to order the parts to build the dimpling tool for a 1/2 coupler.

Most people use a 5/8 bolt for that but you need to enlarge the butt reducer for this (which is 1/2). What's the best way for that ? Otherwise I could use a 1/2 bolt but it seems to be harder to center the pull

Pulling a dimple? enlarging the butt? I'm watching this thread closely . . . .

How much does it need to be enlarged by? - sch40 pipe is 0.622 ID / sch10 pipe is 0.674 ID.

i used a file. a drill bit or a dremel would work as well. just had to knock off the casting marks.

That's what I thought, your looking at 0.003" difference. Worst case scenario is spending 30 miins in the hardware store trying different fittings and bolts to find the set that the tollerances are in you favour

i soldered a washer to each end of the reducer to make sure i was always pulling the tool in the correct orientation. so i guess technically you could find 1/2" ID washers that did the job and just use 1/2" bolt. whatever you use, make sure to lubricate the threads. saves wear n tear on the threads. i had to replace my first bolt because i ran it dry.

[mother of god, there's no way to talk about this **** without inuendo is there]

found these on my phone. no pics of the washers soldered to the ends, but that's pretty self explanatory
