i wish i had a lathe!
i learned to work with them - but have none to use if i have an idea.
so it takes looong to build something from old parts than just making what i need….

Nice. I feel for you when you mentioned boring a large hunk of aluminium out taking all day. Even turning the outside would be a marathon effort. Thanks for the update.
Nice!
Do you have a closeup of the driver? What did you change to make it run at 4s? What firmware are you using?
Great to see another of your creations! I love knurling. Just love it.
Nice work! The knurling looks spectacular and I can’t wait to see the final product.
You might consider running 26650 LiFePO4 cells to reduce the power slightly and have less voltage sag. I did that with direct drive on 3 XHP-70’s with terrific results, over 15,000 lumens.
Also looking forward to seeing what this XHP-35 does at those levels. I have components on the way to use with an LD-2 for a build I’m doing with one of these emitters, should be here today actually. I was planning 2A but now I might go a little higher…
Thanks for sharing, and for the words on Josiah.
Typically you center the part between the two and run an "X" pattern on the part, but I have found I get better results ( especially on a long part) by running one wheel and then the other.
A close up of the result.

Nice work. The knurling looks fantastic.
Thanks for showing how the knurling is made. The tool and the knurling you created are just too . Sure seems like it would take a lot of pressure and consistency to get it right.
WOW!! Fantastic work! Thank you for sharing VOB. I dig the Grizzly
Excellent work really and it was interesting to read how knurling is achieved too. I wondered how it would be done in simple manner. I’ve never used a lathe but I can see how useful it can be for such work.
Another knurly beauty from VOB’s workshop. Looking forward to more lathe, and tooling info… very interesting.
Coming along nicely!
Quite a large update added to the OP. Including LUM 5-90 and more on the head.
Gr8 build man! Your reign has started!
looking good!
I like the reverse tapered head. I dont think Ive seen that done in a light of that size before.
Thanks for the update. I'm glad l'm not a mini lathe in your hands.
that is a bad * club!
great work…
That is going to be one big light! Thanks for sharing it all :-)
About the abandoned XHP35: if at 2.5A the led is at its maxiumum output and 3.5A is well over its max , PWM-ing down from 3.5A will cause the led still to run at 3.5A, just switched on and off by the PWM, and so it will have the diminished output that goes with the 3.5A. In your battery set-up you need true current regulation to get the max out of the XHP35.
