Hi all, Well, I've finally got my butt back in the workshop and started my next project. I am on leave all week so the plan was to spend 2 hours in the morning and 2 hours in the evening each day, the aim being a completed project. After a bit of deliberation I've decided what I'm making. Here are some of the materials: Any ideas? This pic might give a better clue: The wheel was an old casting I got many years ago and machined quite badly but never used it on anything. I thought I could probably put it to some use now so I set about trueing it up in the lathe. Not quite finished, it'll need drilling and tapping for a grub screw. That's all I got done today, I couldn't do the morning session due to other things getting in the way. I am going to do my best to make sure nothing else gets in the way as otherwise I definitely won't achieve my goal. Nick |

Almost right Rob! A few other members will know I've been banging on about making a flame gulper for some time now so this is going to be my attempt! It's going to be based pretty much on Jan Ridders internal valve one just with a few simplifications. I was planning to do a 3D model and draw it up on CAD but that would take some time and I have a good opportunity to get in the workshop this week, so I'm keeping most of his parameters. A few things will need to be altered to accomodate the flywheel and burner though which will save me some time. For about the first time ever I've actually been and bought some materials for this project, they normally come from off-cuts of scrap I've collected over the years but I thought I don't have much time to mess about. I went to a local model engineering material supplier - I only found out this place was about 7 miles from me a couple of years ago but have never been. The materials in the first photo cost £12.50 which I thought was reasonable. 3/8" x 3" HE30 alloy, 40mm cast iron, 25mm cast iron, 2mm stainless and 10mm stainless. Just about to order my bearings from Arc Euro Trade, hopefully postal strike won't affect their delivery! I just hope it works. I managed to make a working stirling engine but I think I'll need to pay more attention to the fits on this one. Nick |

Hi Nick Great price on the materials ,,,,,,,must be great to have some were local,,,,,,,,,Jan Ridders has some great designs ,i have a few of his engine plans ,one day i may get round to building one ,,,,i have a flame gulper there a good engine to run ,mine sounds like a 2 stroke motor , i wish you all the best with the build Regards Rob |

I thought it seemed pretty good, it will be really handy having them just down the road. Here is their website, just incase their prices work out better for anyone, they do deliver and take cards etc. http://www.m-machine-metals.co.uk/index.htm Yes I like Jan Ridders engines too. I've always been fascinated by flame gulpers so it's been on the list to make one for a long time, hopefully I will be ticking it off shortly! Thanks Rob, I think I'll need it! :lol: Nick |
