finished working on the "welding jig" today, we made provisions to insert the back purge argon into each runner individually. at the end of the day we almost finished all of the first run of welds but ran out of Argon gas in one of the balloons so more gas was ordered for tomorrow morning ,we should finish welding up the rest of the runners tomorrow and completely finish welding the whole manifold. distortion to the runners was eliminated by letting the welds cool before continuing to the next so there was no torque and all the runners fit back into their place after dismantling them this is also why we build the second jig in order to hold everything in place while removing the runners to be welded two at a time.
