Final boring pass, bar run in reverse to eliminate deflection caused when machining titanium.
Surefire M600 Scout LightŽ bored for 18mm cell (Please note - Scout Lights use Surefire E-series dimensions & may not work with oversize cells like some 3400 mAh. Cells up through 3100 mAh are recommended.)
Surefire C2 bored for 18650 + custom machined spacer for CR123 cells
This machining service provides bore, ream & hone your Fury/6P/C2/M2/C3/M3/U2/M4 & Weapon Lights to accept 18mm cells. Your light body is first bored to near net size (three to six boring passes), reamed twice to assure dead on straightness & triple honed for final finish. Honing is first done with 320 grit & then 600 grit ball honing tools. The final ball hone operation leaves a super smooth finish but it is not a mirror finish - for that you'll want to polish the bore with a metal polish like Flitz or Semichrome applied on a snug fitting paper towel. Final inside bore diameter is 18.90mm & will accommodate every current 18650 cell made today.
The smaller tube L1/A2/E-series & Scout Lights can be bored for either a 17mm protected cell or for a standard size 18mm cell (like the AW2900 mAh or AW3100 mAh). There's no excess of material to work with so the small tube lights are minimum bored, meaning that the cell will just slip into the bore. The newer AW3400 mAh cells are larger in diameter than any prior AW cell & may not fit in the E-series ... AW2900/AW3100 are the best choice.Final inside bore diameter is 18.50mm & will fit many but not all 18650 cells - you'll need to sort through your cells for best fit.

NOTE #1: most Surefire machining mods don't require the entire light. Please ship only the parts to be machined, usually just the bare body. Removal of the clip, O-rings, combat rings, etc. is greatly appreciated.
Note #2: The newer X-Series from Surefire have thread locker sealant (glue) at the body to head joint. Their website offers this caution:I can bore the X-Series lights with head attached but it is much more complex & time consuming & cost is 50% more than a normal (head removed) boring job. Full details in post #199.The heads of some SureFire flashlights and WeaponLights are fixed in place and are not meant to be removed. If the head of your illumination tool cannot be unscrewed with moderate hands-only effort, then it is not meant to be removed.
Note #3: My shop primarily provides trouble shooting, emergency repairs & fabrication. Flashlights are machined whenever the time is available, meaning that your light may not be machined for some weeks after arrival - lights may be here for 15-30 days & sometimes longer before they can be machined. Please don't send your light if you need it back by a date certain. Lights are machined in the order in which they arrive.
Boring (with head removed)*:
Two cell lights like the Fury P2X/6P/C2/M2/Z2/etc are $42 + shipping.
Three cell lights like the Fury P3X/9P/C3/M3 & any E-Series or L-Series lights are $52 + shipping.
Four cell lights like the M4 are $62 + shipping.
*Recent X-Series light have required boring with the head attached & cost is 50% more than shown above. The Fury P2X is $63 & the P3X is $78
Spacer to fit CR123 cells:
$10 each or $15 for two to fit a 2-cell light
$15 each or $25 for two to fit a 3-cell light
$20 each or $35 for two to fit a 4-cell light
Weapon Lights require a much longer set up & cost more. Unlike any other lights a WML may require as many as three separate custom fixtures, three setups, etc.
One cell WML's are $57 + shipping.
Two cell WML's are $67 + shipping.
Three cell WML's are $77 + shipping.
Elzetta 2-cell or 3-cell (including the Bravo & Charlie models) can be bored from the head end & stoping slightly short of the tail end. I believe this is the best way to preserve the unique tail profile & standard rates apply (see above). On Elzetta please send complete light so I can verify function after machining is done.
Custom titanium lights: single cell lights like the Ti McClickie Pak (1xCR123), Mac's EDC, etc. are $150. Other custom lights priced on request.
Boring the body for either 17mm or 18 mm cells is $63.
Boring the extender is $32 for either 17mm or 18mm cells. Removing the hex & matching diameter to body is $22. Grooving the outside to match the body is $15.
Battery sizes vary widely.
AW18650/2900 consistently measure .725"-.726"
AW18650/3100 measure .722"-.723"
Panasonic 18650/3100 button tops are .729"-.730"
Panasonic 18650/3400 run very large, .738"-.740" (18.8mm)
Please keep this in mind when having your E-series bored for 18650. Those bores may not accept the 3400 mAh cells.
PAYMENT is not due until the work is completed. An invoice will be sent as soon as your work is done. PayPal payments are accepted in USD only. You may prefer to send a check or money order with you light & that is perfectly fine. You may also pay using Visa-Mastercard-Discover-American Express.
