| 'Poppin' Flame Licker |

Hi all, I've had a bit of a break from the workshop after the trials and tribulations of getting my Jan Ridders Internal Valve Flame Licker running. I decided towards the end of that project to make a 'Poppin' flame licker which is a more conventional design> I decided on that incase I was utterly disappointed and couldn't get the other one working, but now I intend to go through with it, mainly as I am intrigued to see how different they are to make and how differently their running characteristics are. It will also introduce some new machining / modelling techniques that I haven't used before. So I bought enough materials to do two when I had my pessemistic head on, basically so I could make anything twice to get it to work if need be! :lol: Now, the plan is to learn from previous experience and carefully make two of everything so I end up with 2 engines! I was going to try to keep this shorter and sweeter than my other build logs as I tend to ramble a bit and it takes twice as long to finish a project! Not sure whether I can do that though - lets find out! Last night I made a start with the cylinder - no pics at the moment but it's still in the lathe so I'll get a couple of snap shots tonight. If I get things right, it shouldn't take twice as long to make two engines as I should save a bit here and there on set up times. So I'm planning on completing these in a month - knowing me and my past predictions, that could easily stretch to two! Nick |

I know - :worthless: I wish I could get pics as good as yours Tim but I don't think they ever will be! Nick |

mine is still on the back burner :( got some home work to get done and i'll get it done :lol: |

Made a bit more progress last night. This was how far I had got with the cylinder. Simple really - face end, centre drill, support with revolving centre, turn to diameter, turn grooves with parting tool (I didn't grind a special tool to width, just recalculated the number of grooves and widths I could do with my tool), drill and bore out 5 thou undersize to leave for reaming with adjustable reamer. Next I needed to polish it a bit and part it off. Then I thought while I had the right diameter I would part off the two cylinder covers. I had already drilled 1/4" through to that part of the bar before hand so all I had to do was countersink each one first then part off: I then got the 2nd cylinder to the same stage as the first so this is where I am up to: I still need to face the cylinders, ream for a nice finish in the bore and drill and tap holes on each end and for oil cup. For the cylinder covers I need to drill clearance holes for screws that fasten them on and lap both sides, one to seal with the valve nicely and the other with the end of the cylinder. So far so good but don't think I'll make any progress tonight, Leeds vs Tottenham game is on (4th round FA cup replay)! Nick |
