Got on with making the valve chest, this was fabricated and silver soldered, I used some hex bar fly cut down to size. The bits for soldering I losely pined together with 1/16" brazing rod And soldered together I squared the fabricarion up as you would a casting, then centre drilled for the valve rod position, and set it up in the four jaw with a wobble bar Drilled it through 3mm then drilled and tapped 1/4* 32*8mm deep Marked out for the bolt holes drilled these through 3mm then used the chest as a jig to spot through and drill and tap the cylinder, and drill the cover 3mm. Slide valve milled a bit of brass to size and milled the vlave pocket in the base flipped it over and milled the cross slot for the rod and cross bar. These are the bit for assy. Slide valve in the chest. That valve cover is just calling out for something. |

Hi Stew What did you do to get the silver solder to run into the joints ?? If anything .. Did you flatten some or does it just run in? What was the grade ? BC |
