This is a holding and precision alignment tool I designed to use when I engrave custom watch dials on my fiber laser.  I am offering this tool to assist other dial makers needing a similar tool and wanting the convenience of purchasing it premade.    If comes with a 35mm opening on the clamping plate.  If you want to make your own opening, I can include a top plate with no opening that is available for your custom finishing.  
Approximate size: 60mm x 50mm aluminum brass blank work-holder, heat sink, and and precision placement clamp with ETA 2824-2 and NH35 dial foot positions and 4 M5 screw down tapped holders for top plate.
Will fit up to a 50mm watch dial blank for workpiece holding and is excellent for heat dissipation and for work piece holding for precision dial foot alignment and placement.
Please note that these products are custom made when ordered and as such we are unable to accept a return on these items.    Please allow for up to 5 business days before shipment.  
Being a handcrafted tool, please note there  will be minor variances in size, appearance, and finish during the process due to these being handcrafted.   Also, I am an inventor, and may make novel improvements or changes to the final design that doesn’t change the functions, abilities, or quality. I do guarantee the function and operation of the tool will be as per the capabilities I have shown on my YouTube and Instagram videos.  As this is a production tool intended to be used as a workshop tool it will come with a 90 day limited warranty strictly for manufacture defects. Wear and tear and any physical alterations to the tool are not included and damage resulting from such is not covered.
Included: one 3-in-1 Dial Tool (Made of aluminum, 4 thumb screws with hex style head)
Instructions For use:  remove top plate (4 screws) and place dial blank centered on holder. If using a blank with dial feet, align the intended 3 oclock position with the 3 clock positon.  Dials with NH35, ETA2824-2, or both will fit into the holder as designed.  If using a very thin metal (less that .6mm) consider using a zinc oxide or thermal paste behind the dial back and the tool to provide a better thermal bond to more efficiently transfer heat.  
Replace top plate and secure with screws in a uniform tighness; do not over tighten.  A light finger tightening of the screws for dialed feet dial is all that is needed.  (The dial blank should be secured and not move under hand applied pressure.)
Each tool will have  a LightBurn template file emailed to the original purchaser of the tool and this file is setup to provide an alignment template. Place your dial art within the 35mm area and the dial 3-in-1 tool aligned in the laser. Confirm alignment and adjust as needed before starting the laser engraving process. 
By using a physical setup of metal guides and the holding tool, and leaving the dial blank in the holder, and laser focus, and physical setup unchanged during production, one can make multiple placements into the laser and achieve precise placement and engraving results. 
To mark foot positions for blanks without feet use an end mill, drill bit, mechanical pencil lead, or other marking device of your choice to place a mark on the metal before removing from the tool holder.  If needing to mark feet that were not produced while in the holder align those perfectly with the 12, 3, 6, and 9 hour markers and center the dial on the center, and then secure the dial using the 4 bolts. Mark the holes with preferred method.
Remove the dial and confirm markings and weld, glue, or use whatever dial affixing method preferred. 
Note to exercise safety precautions: Be sure to incorporate all safety precautions recommended for your laser or machining equipment: wear safety equipment, and follow all safety operating procedures for any tools used with the 3-in-1 tool, to include eye protection.  Never touch the tool during or shortly after laser operation as it may be very hot.  Avoid laser engraving the tool unless you are intentionally modifying it.
