Willy that cylinder is turning into a lot of work mate, but you look like you have it all in hand. Amazing work........ Don
Clever use of the reamer, I wouldn't have thought of that. Much longer cut than a normal end mill bit. Using the reamer like that is a new idea and in use the swarf was like dust and took quite a long time to do..... some more pics..........
If the issue is not melting apart any previous parts, can you go to an even-lower-temperature solder for this, like Tix jewelry solder? Any possibility of a screw fastener somewhere between the two? Though it doesnt look like it - lots of parts in that assembly. It is looking incredible - sure you will get it sorted out.
I'm still having trouble envisioning all the ports and passages in that thing..... I understand the compound principle and the reason for the steam jacket but how they are all positioned in there, along with those removable cylinder liners, is very confusing!! Certainly a pattern makers nightmare!!Pete
