Sorry if I'm asking inane questions....I'm just curious as to how you've solved issues I've come across before
How have you got all the threads the right length/orientation so that all the fittings line up parallel when they're tight....or are the posts just done up tight (and thread-sealed) on the fitting and only far enough into the pillar so that they line up and relying on the tubing g to keep the fittings still?
Hi
More than happy to answer questions.
The core p3 corner posts were machined at a cnc shop.the drilled the holes in them,every 67mm apart.each hole was drilled and threaded to a depth of 6mm
With a diameter hole of 5mm
Each brass peg screws in and stops.all same length when they are all in each peg sticks out 14mm from the pole.all bang on.
The 3mm diameter threaded end goe s into the inside corner of each fitting.
A jig was made and the fitting sat it the jig.clamped each end.
Then a cnc drilled and threaded a 3 mm diameter hole in the inside corner.
We had to machine a small flat surface on the inside corner of each fitting.so. The led ad a flat stop to go up against.
We just tread the fitting on until tight.all fittings are 31.5mm from the post to outside of the fitting.no jigging about.just thread it on and they are all the same length from the post.
I've done a trial fitting,used liquid ptfe and screwed fitting on,I let it go off for 45 mins and connected some PETG up.put some DI water in it and no leaks.
The fitting is tight and level.
