Bosch Router Plate Hole Pattern?

[johnny means]

Anyone know where a measured Drawing can be found? I'm making plates for a 1617 fixed base.

Anyone know where a measured Drawing can be found? I'm making plates for a 1617 fixed base.Got the old base plate? If so, double stick tape it to new base plate material, and use transfer punches (less than ten bucks from HF) to mark location of holes on new base plates. I have used sharpened screws, threaded into router to mark holes. You have to press down really hard, but it's doable.

I measured my Bosch 1617evs fixed router base tonight, I found the hole pattern is an equilateral triangle with the sides of the triangle precisely 4.002 inches with my calipers. I think they meant it to be 4 inches.
521512

According to the calculator, the BCD radius should be 2.3094" and the radius to the line would be 1.1547"

The following routers use this three hole patttern:
STANDARD 3-HOLE PATTERN
Bosch MRC23 Series, 1617-1618
DeWalt 616-618
Hitachi M12VC (fixed and kit)
Makita 1100
Milwaukee 5615-5624
Porter-Cable 690, 890,
7529, 97529 and 8529
Ridgid 2930 Combo Kit

The Bosch 1619 does not.

Place your router base down on a copier or flat bed scanner and scan the hole pattern. Cut it out and stick it on your new plate.

Same idea here. Use the existing base clamped to the new plate. I used a Vix type bit to mark the holes then drilled them the appropriate size.

Yep.

But if you are trying to make them in a vacuum I think Loring has your answer.

I wouldn't trust this, most copiers have more distortion in the copy than you'd think, due to all the lenses and mirrors that the image goes through. I have this same router and it's pretty fussy about the hole locations.

My favorite material for custom bases is synthetic bowling alley surface. It's a bit less than 3/8" thick, solid phenolic, flat, and wear resistant enough to get thousands of bowling balls dropped onto it and slid along it. You just have to get past the fake woodgrain.

I did not know such a thing existed.

Yup, I'm gonna need a minute to process this.
