I had some free time this weekend with my mill. The mill is rough shape. I tried making a new mini pin block but the effort was futile. So instead I dug out the Lumpy Channel base (the top got destroyed by USPS) and decided to make the R-Type 2 out of it. This time I designed a new top with a Center inlet with a jet.
This is a pic of the original base:

Here is a pic of the modified base:
As you can see I milled in the pins and removed a row of pins on both sides of the block. I felt those were mothing more than unnessary restrictions.
Here is a pic of the new all copper top peice:
And here is a pic with top in place:
Next step is a trip to the hardware store for some copper connectors to solder on and some more screws.
