Been making a set of the different sizes of distro plate this week. Front, Rear, Pump Mounts and Flow Meter.
Some of you are probably interested in the details so here you go.
Since I have switched to a
Whiteside 1/4 Inch Solid Carbide O-Flute Cutter which is specially designed for routing plastic I had to get a new dust extraction system. The router was producing more dust and also throwing the dust everywhere as the feed speed is much higher than I used previously. Now running at 3810 mm/Min 18000 Rpm. 1.5 mm depth of cut.
I still have to do a finishing cut with a 3 mm cutter to improve the cosmetics of the water channels but this can be done when the all the screw holes are cut.
I also figured out a way to improve the setup time for machining the second side of the rear plate. I can flip the parts over but leave the Perspex sheet bolted to the table with the zero coordinates set to the same point. Then with some 1/4 inch dowel pins inserted between the parts and the surround which is the size of the cutter used to rout it out the part is in exactly the right location to machine the second side. This way I should be able to do multiple parts at a time instead of setting them up one at a time.
Only three sets of Pump Mounts were needed because the fourth distro plate is for a DDC Pump which does not need these parts apparently.

Flow Meters
I have to machine a second setup on the flow meters to make a nub (high point) for them to spin on. If they were left flat they would stick to the distributor due to surface tension of the liquid.
