I feel terrible now Crying Crying I paid more than you for that little piece. I really don’t want to screw this up.

On the bright side, it looks sweet after machining

Whilst that is true, I also don’t like admitting it to myself Sick

I made some holes in the pill in order to use tweezers to screw it in/out. The holes line up with the mosled holes.

Purrday colours Love

Threaded and test fit

The retaining bezel protrudes a little more than I was planning due to the not being able to machine threads for the pill right the way up to the shelf/step. I should be able to easily rectify this by cutting off 1-2 threads off the pill

I’ve stalled for a bit trying to think about how to proceed from where I’m at with this build.

I bored out the body but didn’t go right through. I tried to stop around where the tail starts.

I then flipped it in the chuck and bored the tail to suit a rubber boot

Cut off the tail section

The inside of the body looks cool Cool Pity it won’t be seen, there will be a sleeve.

The sleeve, to help extend the length a little. Made from a solid bar of ti. The wall thickness is just under 0.5mm and may require a final pass to open the inside a fraction more once it’s fitted to the body.

Ready for threading

Nice work! I need a few more years on the lathe before i would try material like that.

Thanks grin. Your comment got me curious how long I’ve had a lathe, been just over 4 years since I bought the first lathe ( a sieg sc3 ).

I have had a hafco AL-320G for about 5 years i got it to make stainless parts for a brewery I was building. As usual it got out of control then i slowed up on the drink and went back to led grow lights herb garden at first. a “mate” dumped 20 dope plants on me after a blue with his missus and never came back for them. I took the strongest one and put it in the herb garden. That then got out of control with full digitially controlled grow rooms. I was just about to set it up so i could hit it with a frost just before harvest. The day before i planned on starting the build of an ammonia heat pump. The police pulled me up. i had all these leds and nothing to do with them. So i put a 100w into a 6 D cell maglite i had, thought i could make one of those and that put me on another slippery slope. Saving now for a new optimum lathe mill combo it would look good in my dining room with the welder.
Haha dont live on the edge jump off, my apologies for going of topic

The AL-320G is a nice machine. I currently have the next model down from that one. I also looked at the optima combo because I thought I could save on space but didn’t opt for it for a couple of reasons. The work table is limited compared to a regular mill, plus it’s not designed to do 4th axis work. Didn’t really seem worth it at the time. If I had the time and money I would consider getting one and doing severe modifications to make it a 4th axis capable machine. Probably beyond my abilities though Wink

Main reason for a new lathe is an enclosed gearbox, also thinking about the combo so when i work out what i dont need i can buy a bigger table and mount the mill head on it. I already have indexing head, swivel/tilt vice and a heap of cutters. Haha I cant work out if im on the wagon or have fallen off it. As DB custom said it is good fun.

A decent table won’t be cheap Wink

Sleeve is finished. I could probably have reduced the diameter of the threads a little but width is not the issue with this build.

I came up with an idea to save space with the switch. I’ll epoxy the board into the retaining ring.

I thought I was on track to get everything to fit

…but the threads on the sleeve I made take up too much space. It’ll need to be trimmed

Luckily I hadn’t worked on it yet because I had this oveready pocket clip show up in the mail. I have 1-2 bolt on style clips but didn’t really want to be screwing tiny bolts possibly into soft copper. This clip does not fit over the threads on the sleeve so I’ll re-machine the threaded section both shorter length and narrower diameter.

Looking good pp. Its amazing how some problems have to get sorted on the run and how they do get sorted. On the home run now. Beer

I want to see a nice retaining ring, screwed or press fitted for that switch Wink

Maybe I picked up wrong but you said you were going to epoxy the switch into the retaining ring?

I meant the screwed switch module would be better with a retaining ring of some sort.
I’ve found the L4P drivers & switches like a good solid ground connection.

Aah, I see. Thanks for the tip. The board is somewhat of a press fit but maybe a secondary press fit ring would help. Cheers Beer

Yeah, a retainer ring for the inside of the retainer ring, would hold the switch PCB securely, while ensuring better electrical connection than just using epoxy to hold it in.

So I made the press fit retainer, thanks CRX Smile

Also reduced the threads on the sleeve. The o-ring sticks out quite a bit now but by the same token looks like it’ll do a good job of retaining the pocket clip while the tail is unscrewed.

I next mounted the tail in the chuck to start on the internals.

It looks like I had a minor point of delamination from threading

Threads for the switch. I had to drill some holes in the switch retainer for tweezer installation. I meant to do this prior to press fitting the switch board in place but forgot about it Facepalm

Also looked like the smaller threads had some delamination but I think maybe it is more to do with the copper being so soft rather than delamination.

Almost ready to press fit the sleeve in… but not tonight Silly Beer

My guess is it’s been put in the too hard basket. Last year’s organisation/organisers seemed to waiver. Sponsors nearly outnumbered contestants and probably didn’t have the best feeling about it, some prize winners reported not receiving prizes, I think there was a small feeling of discontent from all parties.

Hence I made suggestions after the last contest to have a review of the contest rules.

Even if there’s no official contest I still love the idea of people creating stuff from scratch. To me it’s more interesting than reading umpteen threads about led swaps and tints etc…

If an official contest starts and I’m disqualified or unable to join, it will not deter me. I like making lights on my lathe Innocent but for the sake of encouraging others to have a go I hope an official contest starts. I just don’t hold much hope.

I’m starting to think maybe I should actually go ahead and build mine too. I really wanted the official contest to go on, but maybe it’s a bust now. Oh well, nothing is forever, and we must move on. Anyone who wants to build a light can still do it, without a contest, as you’ve shown. Wink
