Jetbeam TC-R1 MCPCB dimensions

I just got the TC-R1 in the mail. And what a beautiful light it is!

Our missing dimension, the height of the reflector is 12.47mm. I can also verify that the shelf can accomodate a 16mm MCPCB, with 0,65mm to spare.

That makes the original reflector + original MCPCB a total of 12.47mm + 1.92mm = 14.39mm

I am intentionaly leaving out the centering gasket, as I will also use one with the new assembly.

Now, the parts I ordered are reflector + MCPCB 13.4mm + 1.5mm = 14.9mm

That is half a mm more than the original. I ideally need a 1mm MCPCB. I will see if the bezel has the tolerance to screw down as it is, or sand the MCPCB to 1mm and I am done.

I am also wondering if the 1mm thick E21a MCPCBs (2 of them) I am expecting from Clemence will be a perfect fit… I will have to center it carefully, as it is a 10mm board (the 16mm boards are out of stock) but it will be interesting to try!

I used a KD 3535 gasket and 1.5mm mcpcb and this is the difference I get from a factory RRT-01 which the TCR-1 is the same.

If you belt sand the mcpcb down to 1mm you shouldn’t have a problem fitting the factory gasket. As you have mathematically figured out there’s not a lot of difference, and anything you do to lose a little height gets that bezel screwed down further. Using the thiner KD gasket and a 1.5mm mcpcb always worked out for complete coverage of the bezel O-ring with the KD replacement reflector, so I never tried anything else.
