Very nice and I love your fixture. Ya know, flanges could be machined on those elbows by using larger material to start. It would take a bit more work but the flange back sides can be cut in with a parting tool. I'm filing this away for future use...I'd make the radius on the outside of the elbow larger, using the inside corner as the center point. That's just me. You're really moving this along.Pete

You're really moving this along.PeteI think you are right about the back corner, its too sharp. I should be able to take them back a bit more without breaking through to the passage, worth a try on one to see.For the flanges, seems like they would block getting as far to the inside corner of the opposite arm. I am thinking of turning a shoulder into the end of the arm, and silver soldering on a disc for the flange, that could solve the issue for the larger ones that have a bolt flange at the joints. Worth some experimenting...
How did you get the original two elbows to multiply? Dark room nice music and maybe?Just kidding, great job on them! I also find it fun, or at least, very satisfying doing multiple parts of something once a method and fixtures order of ops etc are worked out. Your method is certainly less work than Kozo's built up method for complex ones and I'll keep it in mind for similar elbows I will need to do for the Erie B-2 shovel.
So, about an hour to make the jig and the parts, worked out very well, very happy with them!

A little math...Given:a) About an hour to make the jig and the partsb) 1st post was October 2017c) My rate is about 10xChris (at least!)'a' and 'c' means about 10 times 1 hour = 1 week'b' and 'c' means about 10 times 1 year = my lifetimeIf you disagree with the math...keep in mind the 10x multiplier is a zee multiplier and hence completely bogus.Now back to that word problem involving two trains speeding towards each other.

You are not taking into account that you are in that silly 24-hour-per-day universe, while I side-slipped into one with many more hours per day. Or more shop elves per furlong. Something like that. Hard to keep track...And are the trains steam or diesel? Only makes a difference when they meet on the same track...
