I mentioned in a previous post that my next engine would be a flame licker, I am aware of how fussy they are to get going, despite that I have decided to double the trouble and build a twin. I have downloaded Jan Ridders plans for his "Flame Eater, 2 Cylinder, Internal Valves"

I will start the build shortly.

Interesting looking design; do the pistons move the valves? It appears that there may be a detent ball but I don't see any linkage to operate the valves.

Dave
 
Hi Dave, yes, the pistons move the valves. There is a detent ball with only the slightest amount of pressure to help the valves work. Everything has to move with no friction at all, it will be a nice challenge.

Paul.
 
Looks like this one is being built from the ground up, made the base and feet.
The materials for this were at hand, I have to have a scrounge around for material for the other pieces. I will stain the wooden base a darker colour.

I already found a small mistake on the drawings, it pays to be careful.

A mistake in Jan's drawings? Will you describe it?
 
It relates to the holes in the feet, they specify 3 mm, but a 4 mm screw passes through to fasten onto the aluminium plate that everything is mounted on. I liked the look of the feet protruding out slightly from the timber base, as he shows in the assembly drawing, but if I made them to the sizes on the drawing, they would be hidden underneath. I altered the diameters to get it the way I wanted.

No further progress at the moment, I've had the worst cold / "man flu" for several days now. Itching to get back into the garage shortly.

Paul.
 
Managed to cut out the flywheel blank from some brass plate, using my rotary table, and started to turn it. However, I have been in hospital the last few days having some vascular surgery on my arm, I now have a cut from my inner elbow to my arm pit, don't know when I can start machining again. Maybe I should use the time to do some design work.

Paul.
 
Sorry to hear about the surgery Paul,

Take care and get well soon!

Dave
 
I'm still recovering from the surgery on my arm, still very swollen, but I want to get back to machining. I managed to finish the flywheel, so here is a picture of it.



Ready now to tackle the rest of the build, sorry for the long break.

Paul.
 
I have done most of the work on the cylinder, just have to finally lap a smooth finish in the bores.

Here is the turned blank.


And here is a picture after I turned the grooves in, and getting ready to part off.


Next, I bored the cylinder holes in the mill. The boring bar had a bit too much overhang and caused a bit of vibration as you can see. I have already honed out the chatter marks and will lap a smooth finish shortly.


Here is the nearly finished cylinder block. I only have to machine the air inlet ports in the 2 sides.

Looking very nice Paul. I've always liked flamelickers. I toyed with the idea of building a 4 cylinder horizontal flywheel 'radial' flamelicker as my second build. Maybe I'll revisit the idea once I clear up a few projects.
 
This flamelicker has 2 different sized bearings and uses 2 of each, they are MR63 and MR105, 3mm and 5mm ID's. I was going to drive to a local bearing suppliers, but decided to check eBay first, I was very happy that I did. I can but 10 of each for A$5.04 total delivered to my door, I can't even start my car and drive to the suppliers for that price. For an average of 0.25 cents for each bearing, I'm delighted. I just have to pop the seals off the couple that I need and wash the bearings out to reduce any friction.

Paul.
 
Hi Nicolas, been a bit busy lately to do much, but I managed to machine a few small bits today. My friend Eddie, who is also a member on this site, dropped in a load of graphite so I can machine the pistons soon.

That's looking good Paul, and you are lucky to have a supply of graphite. It is messy stuff to turn but the lathe works really smoothly afterwards.

Jim
 
That is really a great work. I'am struggling al the way around too build the one cilinder from Jan Ridders.
But keep the good work going on & I hope you have a great runner.

Barry
 
A little bit more work done inbetween interuptions. I now have an aluminium sub base plate.



Some cylinder mounts and a roughed out fuel tank. Jan made his fuel tank from 2mm sheet, not having any available, I made mine from a solid block and I intend to solder the lid on.



And here is a rough assembly of some of the bits.



Paul.
 
G'day Paul, been meaning to come on for a look/see and find out how the build is going. Sorry I had to leave in such a hurry the other day. Wish I could have hung around a bit longer, but I am sure you understand.

I am really looking forward to seeing this one come together, as I find the flame licker's very intriguing.

Don't forget to mask up when machining that black stuff.
