Thread: Surefire boring service

  1. #1

    Default SureFire® boring & machining services

    I can bore, ream & hone your Fury/6P/C2/M2/C3/M3/U2/M4 (and most other models) to accept the AW18650 or similar diameter 18mm cell. The smaller tube L1/A2/E-series can be bored for either a 17mm protected cell or for a standard size 18mm cell (like the AW2900 mAh or AW3100 mAh) but they cannot be bored for the much larger 3400 mAh cell. PM's are disabled so please click on the "contact" page at www.PrecisionWorks

    PLEASE NOTE: This is the original thread started in May 2011. Some services that were offered before are no longer available (trit slot milling, bead blasting, etc.). Please refer to the current thread for up to date info on boring: http://www.candlepowerforums.com/vb/...itanium-lights

    Please refer to the separate thread for info on mechanical mods: http://www.candlepowerforums.com/vb/...dding-Services


    NOTE #1: most machining mods don't require the entire light. Please ship only the parts to be machined. Removal of the clip, O-rings, combat rings, etc. is greatly appreciated.

    Please note ... you now have two options for speed of turnaround:

    1) I now offer 2-week turnaround for twice the delivered price I've always charged (i.e. $100 for a 6P, $120 for an E1 or E2, etc.)

    2) Or indefinite turnaround for one-half the price of 2-week service (i.e. $50 for a 6P, $60 for an E1 or E2, etc,). Indefinite really means just that, I will not give a time frame or quote a date/month/etc. if you choose this option.

    Do you offer any bulk discount, or combined shipping? I assume at this price it will be bored the same day, and shipped the following day? If so, I could be interested, as I am very impatient.

    That sounds great, Chris

    Do you offer any bulk discount, or combined shipping?
    For 5-9 lights that are shipped together, take 5% off. For 10 lights or more, take 10% off.

    I'll certainly combine shipping whenever possible. Just a wild guess, but probably 10 lights would fit into a Medium Flat Rate box, with substantial packaging, for $10.

    I assume at this price it will be bored the same day, and shipped the following day?
    I will guarantee that ... just double the price

    Seriously, my normal turnaround is 2-3 days. Your light (or lights) will be shipped no later than the day following machining. I appreciate what you say about impatience, and every job that comes into my shop is important to the person that needs their work done. At the same time, enlarging a thin walled tube is not a job that any machinist wants to rush through. The method I use is not the quickest nor the easiest, but it consistently produces high quality results, while maintaining both the integrity and the appearance of the light.

    Can you bore a 3P?
    The 3P should bore out just as nicely as a 6P (or 9P). I am set up to bore to an inside diameter of 0.738" (18.75mm), although other ID's can also be bored. What battery are you planning to use? Can you measure the battery outside diameter & post back that dimension?

    For those that are unable to measure a battery diameter - would it be wise to ship the battery with the light being bored out?

    It certainly would, Will. That allows me to accurately measure the battery & then add a very slight allowance for clearance.

    That's a great suggestion

    Ken asked if a 3-piece body could be bored, and I believe it can. If anyone reading this is unsure about the body they want bored, please send it to me along with the batteries that will be used. I will measure the body & bore if possible. Or I will return the body and batteries at my expense if the body cannot be bored.

    No problem to work with international customers. The International Small Flat Rate box is a bargain, and probably two light bodies would fit inside with good packing. Shipping rates for international go up fast for the larger cartons.

    I can also bore/ream/hone longer lights like the M3 or M4. They involve more machine time, so the cost is a little higher. $48 for the M3 and $56 for the M4, plus shipping. Same turnaround time, about 2-3 days in my shop, and return shipping within one business day after completion.

    And returning your M2 in the mail this afternoon

    My shop will be closed for the holiday (5/27 - 5/30) & I wanted to get the M2 back to Chris without the holiday delay. A few "after" photos ...









    The last photo shows the small lip that was left in the bore. This gives the 18650 a positive forward stop. The RediLast battery is just slightly larger than an AW18650, but there is still .010" total clearance (or .005" radial clearance) which is more than enough room for an easy, drop in fit.

    VanIsleDSM makes them. 5.6A quad XPG 1600+ OTF Lumens. It's insane for a light that small to put out that many lumens.

    Any thoughts on doing E2 bodies to 17670? They should only need 20mm in the tail end bored.

    doing E2 bodies to 17670?
    I haven't handled an E2 in some time, but the external appearance of the tube looks like it should work (for securing in the lathe). Pretty sure I'll have to bore a custom set of soft jaws for that size tube, but that's not a big deal ... my soft jaw collection is growing

    They should only need 20mm in the tail end bored.
    Are you saying that only the first 20mm of the tube, on the switch end, needs to be enlarged? That can certainly be done. If you don't mind sending the complete light (plus the 17670's that you plan to use) that would be best ... I can measure, bore/ream/hone, and verify operation of the light. Same pricing as a 6P, $40 plus return shipping.

    Thanks Barry, great job and super fast service!! When I threw that Redilast battery in there it was honestly wishful thinking on my part. I have a couple other bored Surefires from various modders and these fat Redilast cells usually don't fit well. But you made it fit perfectly, thanks again!

    Euroken sent a message asking if I would "provide a boring service for non SF host ...and, second, whether you would bore a three piece body." The answers to those questions are YES and YES

    I was initially concerned about maintaining adequate wall thickness, but measurements showed that the body could be bored/reamed/honed while still leaving good wall thickness. It took a little while to figure out the fixturing on the lathe, but nothing insurmountable.







    these fat Redilast cells usually don't fit well.
    +1

    They measure quite a bit larger in diameter than my "standard" AW18650. The AW cells end up with about .010" radial clearance, while the RediLast cells have just .005" (about the thickness of a business card). .005" is plenty of room, as there is .005" all the way around the cell. Happy to hear that you are pleased

    LOL, that means you are NOT the member from London Which is better, as Priority Flat Rate is only $5.

    That tube is nicely made and all the threaded joints fit together very well. You'll have fun with it, whether you use it as a 6P or a 9P.

    Yeah, the tail threads are small (CR123 won't fit through, about the same diameter as the threads), the batteries go through the head end. A 17670 fits 90% of the way but the body narrows near the tail threads. You will have to bore from the head end.

    Cheers,
    Nova

    Nova, that shouldn't present any problems. My first concern on boring any light is to leave adequate thickness, especially at the O-ring groove (normally the thinnest part of any flashlight tube). Surefires have a (relatively) thick wall to begin with, and I use the minimum bore & ream diameter dimension that allows the battery to fit with just a bit of clearance.

    If you want to ship your light, I'll be happy to examine it & determine if it can be bored (which I believe it can). If for any reason it cannot be bored, I'll pay the return shipping to Australia. The fastest way to contact me is an email to precisionworks AT frontier DOT com.

    Got my 3P body back today, not bad, one week from shipment to receipt, with a holiday to boot.

    Very clean work, no evidence the body was ever toouched, and the bored tube is super smooth, with a nice lip to hold the battery and make contact with the drop in.

    Thanks Barry!

    Got mine yesterday.

    Very well done, with buttery smooth bore. No sign of any anno missing on the body as PSM mentioned. The bore fits all my 18650 batteries, even the ones that are slightly largeand would jam in my other bored hosts.

    In addition, talk about communication and prompt responses! Great experience as a whole.

    Look forward to possible e series bores!

    Cheers!
