I need some help. So far everything I’ve done has had a perfectly circular milling layer. How do I do other shapes accurately? Like an SRK driver with the tabs, or a tailboard in the SRK “flower” shape or for a ZY-T08?
Hey… I am really stuck on the same issue!
Draw your basic outline, then use the split, miter, and meander tools.
Easy for you to say Richard! But this comes from a guy that build a D01 contact board and could not make a basic FET driver fit on board… I really suck at that program.
I’ve never touched any of those tools… I’ll have to play around with them and see what happens.
Thanks for the tip. Now that you know somewhat of the extent of my inexperience, feel free to keep the tips coming 
For tabs I make them first and use arc to get the rest of the circle.
I just draw wires on the milling layer. If I need part of a circle I draw a full circle in the reference layer, than draw an arc in the milling layer and trace the part of the full circle in the reference layer that I want. I’ve never used the commands RMM suggests, I’ll have a look at them next time I need to do something like that.
A few more options, all basic BLF designs, but with added stability components. Part lists are on the various OSH-Park project pages:
—
DDm17 rev03 - Built and tested.
—
DDm17 rev04 - Ordered, but still en-route.
Rev04 is a slight modification on rev03 to get more clearance for the programming clip.
—
DDm20 rev00 - Just ordered.
—
DDmY3 rev00 - Ordered, but still en-route.
For the Yezl Y3 (1S).
—
DDmM6/SRK rev01 - Built and tested.
—
DDmM6/SRK rev02 - No plans to order.
This one gives the option of one to eight 7135 chips for the regulated channel.
—
1400m rev00 - Built and tested.
This one is a favorite of mine for Convoy S-series lights! It is what I use in my EDC S3. Two regulated channels, based on Harlequin’s HQ4D board. Note: Only good for 1.4 A.
Thanks DEL. The latest items I’ve ordered and just received thanks to this thread is the 15mm 7135 driver boards and the boards for momentary switches. Hopefully I can get a driver to work. :person_facepalming:
I got a bunch in already, and a bunch more due in this week, including the Y3's! Thanks DEL!!
Wow. What a mission. Well for me it is anyway. I have just happily, after many failures over along period of time, managed to build my first working driver. Its the 15mm SK68 driver by WarHawk here.
I used an old 7135 driver for parts that never worked, flashed the MCU with TK’s Biscotti and we had light. To everyone involved, a big thanks. Yes there were lots of you here that has helped me over an extended period of time from soldering, flashing and answering many questions. YAA HOO.
You finished! ;-) I guess you have better luck with drivers than with motorcycles. That driver looks great, by the way. Congratulations.
Thanks Richard. Now to assemble it into a light.
Usually, with you it is "now to machine a light from bar stock to fit the driver..."
Not quite this time. I’ve used this light peering down machined holes for along time now. Its ideal being a small zoomy being able to adjust the beam pattern to suit what your looking at. However it had a next mode memory driver with the dreaded flashy mode. The pencil mod on the capacitor only made it cantankerous. Due to a suitable driver not being available put up with it until now.
Another chip was added to make it five in total with an XPE2 Torch led used for lighting purposes. Shims were added to only allow the zoom I required. Dont laugh to hard at the flashlight itself. Yes it was cheap and very nasty. 
Congratulations, I have mixed success building them. Bad eyesight and short, thick fingers but still game.
I've done a few of those a while back using different drivers, FET and 7135's. They go pretty fast, hard to keep them around. I shorten the sliding piece to create a wider zoom area - works for most of them.
Nice Tom. So there are athers thatspend far to much time on crappy lights. I’ve got an Ultrafire that seems a lot smoother on the zoom and slightly larger lens that will get the same treatment next.
Not to mention shaky hands RBD.
Nice. I also have a few of those lights around...stock, FET, FET+7135, and boost (AA). Nice little lights.
Any 30mm FET+7135 Driver boards ??
