This week work on the B16 has continued to flow.
The lubricators are on and although you get plain castings I drilled them out to add the pipework inside some microbore tube that I picked up earlier in the year from Barry of MetalSmiths fame.
There was a thread on the Guild site discussing drilling brass castings and one of the suggestions (besides buying proper drill bits) was to heat to a cherry red heat and let the casting cool naturally. I have used this method before and it has to be said without much success. I decided to try again and I have come to the conclusion that previously I just didn’t get it red enough – this time the cheapo Microbox type drills went through it like butter. I did you my Proxxon Mini Pillar drill though.
You know when something niggles at you that there’s something not quite right? Well I had the feeling and finally pinned it down to the fact that the chimney was just not quite on square so I heated it up and attempted to nudge it. I must have been a bit vigorous because the next second it was on the floor. The good news is that in knocking it off I had spread the solder a little in the right direction and putting it on square was a simple matter of putting it in place and then heating it with the microflame until it sank down in the solder. A little cleaning up and I was happy
