Thanks for the feedback and suggestions. Lego?! I didn't know about that option. I did decide to redo the little loop, with much better results.
And I am now ready to fill and leak test!! Can't believe it :biggrin: Please don't leak...
Here's the progress from today.
First a little local shop saved the day and sold me a G1/4 stop plug for the top of the reservoir. That was going to be a show stopper obviously. They don't sell custom cooling parts but they do custom loop builds for people. So I took a chance and asked if they had a spare they'd be willing to sell, BINGO!
Next, fixing up that little loop. This is how bad the pinch was, couldn't life with that, so redone:
And I was able to adjust the offset of the two ends a bit so it isn't touching the pump mount; didn't want any extra vibrations. Installed:
Next was the output of the CPU block. Again here I had to switch to a 90. Unless I had done several more complicated bends I definitely couldn't get the sharp turn to the left. I did experiment a bit with more elaborate bend combinations with both the CPU tubes but I just could get something I liked the look of. Much more practice would be required. But in the end I am pleased with the end result. It is the clean simple look I was hoping for.
The output tub is a very slight amount off square to my eye. However not noticeable enough I didn't think to redo the whole tube. I don't think I would lose too many points for it but you guys can be the judge... I can take it!
And last the final bend up to the CPU input. For this one I wanted more tube visible rather than fitting so I stuck with the straight fittings and a simple 90 bend (still took me two tries... :doh

to the CPU. I tried a set of step bends from the GPU up to the CPU but again, beyond my current skills. Couldn't get the bends and the lengths right. Old K.I.S.S. principle won in the end.

and overall completed loop :thumb:
Off to do some filling!
