"D" Mag Mandrel... Image heavy

Thanks Dale.... I'll post some images. I'll scratch something into it!

Agreed, I enjoy lathe/mill/etc pictures as much as the build pictures. So, keep them coming. :)

Not busting your balls, your machine work looks very good but by the look of the threads in the picture your compound was set to the wrong angle. It should be at 29 or 30 degrees from perpendicular to the work.

The threads in your pic look like |\|\| instead of /\/\/\/\

Yours looks to be set to 30 degrees from parallel from the work. This is very common since the protractor scale on lathes are not standardized. Some read the angle from perpendicular. Some read the angle from parallel.

Mine reads from parallel, so I have to set it to 60 degrees instead of 30 when I cut single point threads.

mrpete222 on Youtube is an excellent resource. He talks about setting the compound at about 4:30 into the video.

Here is a Mag heat sink I made that screws into the head.

Cheers,

Love it. I find so dramatic to see such industrial machinery works. :smiley:

11

I thought the same thing, I figured it was just the picture

12

Looks great! Keep up the good work. :wink:

13

Thanks for the note... it is the image, we run 29 degrees perpendicular to the work. You are correct though, this is a common mistake and it does depend on the machine. Thanks Again. Dan.

I saw that as well but didn’t understand any of the degree lingo as I don’t do threads. But when I saw it, I looked at it closer and saw the angle of the picture, the angle of the light, and realized that the forward pitch of the thread was on the shaded side and the camera was centered on the face of the chuck itself, so the optical illusion came into play that the threads pitch was off. A closer inspection shows the typical inverted V shape.

Gimme more!!! :slight_smile:

I hereby officially apply for a handmade HD2010 with exacting fit and finish made in Titanium grade 23. :slight_smile: (T6061 would work but I AM a Ti freak :wink: ) With a caveat. I ask that it be a production in miniature, utilizing an 14500 cell. This cell is a good down scale of the 26650. Can do? :slight_smile:

Copper pill, of course! :stuck_out_tongue:

15

That would be a neat looking little light scaled down to a 14500 size. But Ti 23!!! Yikes! I just felt my tooling budget rip my wallet right out of the o'le pocket!! I might play with that scaling though... I like lights with the larger head like that HD2010. Hmmm... you're doing it to me again aren't ya! Dan.

16

7075 will work. Doesn’t have to be oxygen free 6Al4V. Besides, the piece of that I had in 1” bar is now the light in my avatar and hanging around my neck. :slight_smile:

You get serious about scaling that one down and I want a shot at it, ok? :wink:

17

Dale, I'll play with it and since you are the one that gave me the headache....errr... had the thought of doing that, you get the first shot. I might do one in Ti-4, I don't mind working that too bad. I'm behind at the present but I am catching up slowly...of course, that's what I thought six months ago!! Thanks for the thought!!

Encouragement, you’ll get there…

What if you machined the reflector as an integral part of the head? The pill could deliver the emitter into the reflector from behind, with the battery tube threading in right behind it. Just because it’s Externally the same, doesn’t mean it has to be internally the same as well. Then the head/reflector would be one solid piece, adding to the heat sinking effect. For this reason alone, it should be made from at least 6061 if not 7075.

I have found a way to polish the aluminum such that it is a mirror, with virtually no markation. Now wouldn’t THAT be cool

20

Speaking of trying to catch up, there is always something else pops up to interrupt. There is a certain member out there has given up on me. :_(

21

Here’s a better example, with different lights for size. And more what if’s…What if? You made it out of solid copper? :slight_smile:

Who gave up on ya Steve? :expressionless:

22

I cant embarrass myself needless to say progress has been made today.

I’m still waiting on this mandrel to turn up. I hooked the fax back up especially and nothing has come through yet. Glad to know I’m not the only unreliable thing around here. |(

23

i still think an m3 head with a 14500 body would be mint.....

just need to match the dimensions on the head and tail of the body. last i checked, it would be like $60 for the battery tube to match solar force dimensions

24

Churn em out and we’ll buy em! :slight_smile:

The Scaled down HD2010 could even be made smaller for a 10440 as far as I’m concerned, now wouldn’t that be neat. :slight_smile:

So there ya go guys, a challenge. 3 of ya yappin and no lathework showing up! Dan, Nick, Steve, spin em up and lets see what ya got! :slight_smile:

25

Wow... that's one ugly red light!! At least it hasn't melted!

Dan.

Whew! I'm sending you my lathe! I wouldn't want to do the reflector as part of the head.... but I do make a lot of lights that the pill pocket, head and short portion of the body are one piece. Then, the tube screws onto that. This can make it nice for changing battery sizes on the same light. That's all probably clear as mud after I re-read it.... an image is in order, I'll scrounge one up. Making that reflector part of the head means of course that you have to shape it into that head... working in a hole!! It can sure be done but would... for me anyway, take awhile.... Steve did something like this I think.

I make almost all the aluminum parts in 7075. I use 6061 sometimes for internal parts like lock rings & etc... but the 7075 T61 or T65 seems to hold a finish better after blasting. It certainly holds a high polish better and for much longer than the 6061.
