I went a head a started the side project for this summer. Thanks to a link posted on the Polarstar HPA Gas Box thread I downloaded the plans from http://kuba-t1000.com/minigun/index.php?akcja=tutorials_airsoft_aeg_to_hpa_conversion_mod and bought two feet of 1" diameter T6 extruded aluminum round rod from here http://www.onlinemetals.com/merchant.cfm?pid=1090&step=4&showunits=inches&id=195&top_cat=60 .
So far I have built the external spring guide. Its a little out of spec but I think it will still work. We'll see.
