JB Weld for brass?

Earlier this year I bought the 'Gaunt' pillow block eq mount from Matt aka Kunama. This beautiful mount takes my 6" f12 refractor with ease. Its all there except the RA setting circle, RA gear and tangent arm for dec control.
I'm well on the way to rebuilding all these parts, at least theoretically!
So far I have partly built the tangent arm and have just made the RA setting circle.
Pics below show what it is. Two discs of 6mm brass with a 3mm aluminium disc sandwiched inbetween, to match the exsisting Dec circle. I need to bond the circle together. Will JB Weld to the job? Any other suggestions? The RA circle will then be bolted to a 12mm thick aluminium disc which in turn is secured onto the shaft via grub screws....This aluminium disc will then become a component of a friction clutch system still in the pipeline.
Photos show the mount and brass discs.
Of course there is engraving the 8" circle with the hours which is another hurdle to get over....ideas thoughts on this?
