bosch gof 1250 LED light

I wanted a LED light for my Bosch GOF 1250 CE router. 
(There is a version that has LED included, but i don't have thist one.)

I wanted a switch, so I can use the light, also when the router is not running. And I wanted to be able to switch the light off, when changing the bit - without sunglases ;-)

I didn't want a battery solution.

So I designed a case for a LED-Driver (Self Electronics SLT3-350ISC) and a switch (opening 13x19mm) to mount at the outside of the machine. Only one screw is needed - the hole does already exist.

The power supply I took from inside the handle - at the power button. There is a way for the two (L , N) wires inside the machine. I had to take off the top and the base of the machine to put the wires inside. 
!Take care about the motor-brushes when taking out / reassembling the base together with the motor-rotor!

I didn't redesign the original black cover around the shaft. But I had to adjust it: holes for the input and output wires, creating some more space (with dremel) for the solderd wire-connections.

As I used a LED Ring there was the Problem, that it coverd the two screws of the original cover. The first attempt was to use a bigger (70mm) LED ring, giving space for the screws. But I didn't like it, because it was so big, that the visibility was worse. So I used a 50mm LED Ring. I designed a “holder” witch is mounted with slightly longer M4 screws together on top of the original cover. The LED ring sits on top of it an is hold by a “cover”. There are two holes in the side of holder an cover to secure the cover with small screws. But the screws are not needed as the cover has a tight press-fit. The roughness of the print helps to hold the cover in place.

The whole setup messuers +9mm - so it is still enough space for the wrench.

!It was neccesary to use the thiner wires (came with the LED ring) to realize a slightly flexible connection around the corner! I secured the wires with some hot glue.

The “case” needs support-material for printing - for the “holder” the result is better with support.

Assembly:

1. Print the three parts
2. Put wires L + N in the machine
3. melt two M3 Threaded inserts in the case
4. screw the driver in the case (there ar two channels under the driver for the wires)
5. put the wires for the switch through the opening - solder the wires to the switch (due to limited space, keep the wires short)
6. mount the ready cover on the machine
7. prepare the original black cover with the holes and the space for input and output wires
8. put the wires in the original black cover
9. mount the LED ring in the printed “cover”
10. put the thin wires in original black cover
11. solder the input and output connections and cover them with shrinking tube 
    !limited space! 
12. mount the “holder” together with the original black cover (2 longer M4 srews are needed)
13. clip the “cover”  - with the LED ring inside - on top of the “holder” 
    !wires have to be short!
    !hotglue helps to avoid breaking out of the connections on the LED platine!

Result:

Bright daylight under the router :-)

May it be useful…
