Looks great so far. 
+1 I love seeing machining set ups
Very cool mod.
Time to assemble and test. We will be making some additional mods if possible.

Is there a resistor mod that can be done with some improvement in output ?

Wow, it checked .287 thick core. That is approx .640 total under the LED.

Here you can see a doughnut hole in the middle. Any suggestions how to stop this ?
This was a 4500k XHP70 LED i think, looks soft white on the wall.

AFAIK that reflector is better suited to small die LEDs. I don’t think you can completely eliminate the donut with an mtg2.
Nice mod CNCman. 
Changing the LED to an XHP70.2 and slicing and dicing it might be a good way to go to resolve the donut hole issue and improve output a bit.
I thought that to pinkpanda3310, so after checking the reflector on Aliexpress, will this be ok for the XHP70 ?

Thanks everyone

Hoop, Yes that is a good idea so I will order one today. It should be here in time.

Looks like the same reflector to me.
I was going to ask if they spun out on higher RPMS…I usually would use a parallel as a back stop, set the part and tap it out…
nice work!
Is the donut hole only visible when white wall hunting?
.
Sorry for the late reply. I took it out for a walk last night and yes it was actually big at longer distance.
.
Also noticed it was quite a bit HEAVY. So i weighted it at……

The Buffalo was hungry over the Holidays. 
I think I gained some weight in the last few days too…… :laughing:
There’s no good way to eliminate the hole other than LED swap.
To eliminate it you can:
- dc-fix it
- find OP reflector
- (?) mount the LED out of focus
Each will significantly reduce throw.
Different LED is what I would suggest…
.
I have a XHP70.2 P2-1A 4292LM 6000K on order from FastTech to swap for the competition and maybe slice and dice. 
That is the best I can do for now. Maybe the donut will shrink some.
Thank You :+1:
Only decent results I have had with that reflector is xhp35HI
Have you tried a different led yet, CNCman ?
.
The XHP70.2 is was shipped from FastTech ( China ) Dec 27 2019, not sure it made it out before the China New Year celebration… :person_facepalming:
Also ordered some testing equipment that has not arrived yet. I wanted to get some numbers for comparison between stock and mod, so it can be put back to factory quickly get numbers, then start chopping again. 
If was actually shipped on that date I think it should be okay
“The Chinese New Year of 2020 falls on January 25th (Saturday), and the festival will last to February 8th, about 15 days in total. 2020 is a Year of the Rat according to Chinese zodiac.”
I really like that nice SS bezel. It is much more prominent than the original one. The MT07 Buffalo should be designed like this. 
Good idea to fit one of the biggest reflectors around for an awesome XHP70 thrower.
