But the result is that many many people love the D4 now, which is for an important part thanks to all those hours that you spent on it 
2nd batch Q8 is here .
Left 2nd batch - Right 1st batch
Tube now has rounded edges , inside & outside :
Springs are identical :
New screws with round head as already mentioned :
Head , they sit lower than 1st batch ’s screws for sure :
Rounded edges , pcb sits better this way :
Wow, nice George! Just a few mins ago I got a new one in my hands and seems to match what you got there, but didn't do a tear down - I'm at work. The beveling of the drilled holes is a nice touch! - takes me a lot of time manually trimming with an Xacto, then sanding.
Hope the driver thread holes are done the same way.
Bad news on the springs though, least for me. They apparently did not deliver on the springs we were shown in pictures - probably would have delayed shipping because it all happened on the late side, so probably dropped. If 100% identical, then the same stiffness I suppose. I'll check some time today, taking full measurements of wire thickness, etc.
Tom, sounds like you need a deburring tool.
Ohhhh - didn't know they existed, yes I do need one! K, gotta do some searching...

This one seems popular, good reviews: https://www.amazon.com/Deburring-tool-Blade-Extra-Blades/dp/B01L2XR4P2/ref=sr_1_1_sspa?ie=UTF8&qid=1507904289&sr=8-1-spons&keywords=deburring+tool&psc=1
You could just use a much oversized drill bit. It’s very quick.
Or a countersink bit
I was trying to suggest tools people may already have.
I simply use my Fiskars scissors. Scrape the edge away and carry on… takes mere seconds.
Not sure how to use scissors on those tail board drill holes, but I do have countersunk bits on order, so maybe will wait til they arrive and try them.
The mechanical modding stuff is not my area of expertise for sure, but it's more fun doing to me. Just wish I had more of a "machinist" background because a lot of the language, tools, methods is not familiar.
Damned smart post. Yesterday q8 was a half hour away couple towns over. Now it’s in another state and pushed back again a couple more days.
Can’t wait until monday!!!
Smart post seems to take the dumbest possible route 
Tom now you get Barry and my position a lot of the times
Well said about Banggood, once they actually ship the package… the ball is in the shipping companies court.
I did not know that about the “algorithms”. That explains a lot. :+1:
Thanks for sharing that…… 
Good… glad it worked out in your favor nvanlaar!!
Where did you get that little folding chisel/pry bar in your pictures?? I sure do like the looks of it……
I have never intentionally bought one, but have 3 or 4 lying around because they often come with a set of drill bits, same goes for centre punches, more people have them than would ever think to buy one deliberately.
I have received the Q8.
When in max brightness mode, after 3 seconds it blinks 3 times and goes to lower brightness. Same thing happens at lower brightness until it gets three more lower brightness mode.
It is not related to temperatures because it happens when it is cool as well.
Maybe it is related to battery? This did not happen at full charge. But this is now happening with 3.4Volt charge. Batteries are 4 button top 18650-30Q
Yes that is normal, Low Voltage Protection
Just finished sending PMs to those with issues, IF YOU HAVE NOT GOTTEN THIS PLEASE PM ME
My third Q8 beat the second to California, the 1st is still lounging around in Sweetwater, TX. Funny, this 1st one must have an affinity for water as it first hung out in Palm Springs before taking up temporary residence in Sweetwater. Hmmmm, a dive Q8? lol
I have three pairs of scissors I use at the bench, the smallest has blades 1 3/8” long, the next 2 1/4” and the largest 3”, the two smaller ones have very sharp pointed ends. So even a small threaded hole is not a problem to debur with the finely ground steel blades of quality shear’s. I use scissors to strip wires, cut wires, clean epoxy (cured) off a toothpick so it can be used repeatedly and whatever else they seem relevant for.
Dale , can we bet on the Q8 race ? Haha
I’m fully qualified for through hole soldering. My experience level with SMD is limited to building Reprap electronics using solder paste & hot plate. Then I’ve also repaired a Nikon flash by replacing a SMD diode and inductor. So you could say I’m a novice with SMD work.
I’ve got a nice Weller Digital Iron. I’ve been wanting to buy a hot air rework station, this might be just the project I needed to justify the purchase.
