SOLD! The Last Valentine Nano Bee

Post  ukanduit on Tue Nov 27, 2018 4:56 pm

I have a legendary Valentine Nano Bee for sale.

Honestly it is more of a novelty than an actual usable engine IMHO.

It is like new.

I purchased it from Ronald and he told me this was the very last one.

I recently paid $500 for it.

Price is $500 and you pay Paypal fees and shipping.

Thanks for looking Smile

Neat!

I have to ask why you are selling for the exact amount you paid?

You paid $500 and are selling for $500. Usually people try and make a little money when selling.

It’s not a big deal or anything, I was just curious.

Got it, is it possible you can post a picture of it sitting on a quarter? Some people might not realize how small that engine really is.

It would be cool if he had made some these small ones with TD .010 glow plugs for those that don't want
to fuss with diesel fuel. Little RC carb and muffler would be shaweet.

I've never seen an engine that small, could power a peanut scale or Bostonian!  Shocked  Tired w/ Coffee Read  Smoking

It's a real jewel given its rarity and so small.
It could be mounted on a ring, bracelet or dangling from a gold chain. Beer Cheers drunken Popcorn Babe Bee lol!

The steam engine I designed and built, it is even smaller than Ron's engine. It is a 1/16 inch bore and stroke so that makes it 0.00019 cubic inch swept volume.
It runs and runs well.

My own design and from scratch.
I was inspired by Dr Senft's Thimble engine.
My design is less compact but in my opinion a (slightly) better layout.
His design has an ever so slight unwanted torque moment... but, still an excellent design nonetheless.

That steam engine is really cool!

I too have always wondered why Valentine didn’t make Glow Nano engines. I realize they are just for show, but they do function. From what I hear they break quickly if run.

Diesel engines cause more stress on the working parts so at that size I could see it not lasting long, that’s why I was wondering if glow wouldn’t have been a better option.

Anyway, I hope it goes to a good home. Maybe Crankbndr will buy it, he is already in hot water anyway... lol!

one CEF member across the pond has many of Valentine's micro engines.....some where here I think he discusses running one

IIRC the small propeller was a pain to source or make...not enough mass for easy starting

for life of me I do not remember if it was Ian or who(m)

Thanks Eric...Yes it was indeed Ian..I miss him dearly and hope his health has improved...hopefully he is lurking

regarding Ron making the nano engines for glow fuel....Glow plugs would need to be exceedingly small

I seem to recall there is a chemical or some practical limitation on how much Platinum is required for the catalytic reaction with methanol ---also glow plug in nano miniature--- the element would probably need a special heater voltage

Diesel made more sense in a lot of ways

With the right tooling Ron could halve the size two more times and still have a running engine

No mater how small we think this nano work of functioning art is---- it really is thousands of times bigger than the smallest working machines we have created in the 21st century

SOLD! Glow engine

Post  rszanti on Thu Dec 13, 2018 1:15 pm

Ron did make a glow version - I have one of each, a  glow and a diesel. I have not run the glow but did discuss it with Ron and he assured me it does function well, we  did not talk about longevity.

I have run one of these wonderful creations.

It is hard to imagine that it was created manually (no CNC) on one of these:

A Triumph 2000 lathe

http://www.google.co.uk/search?q=Triumph+2000+lathe&hl=en&rlz=1W1MXGB_enGB524&tbm=isch&tbo=u&source=univ&sa=X&ei=AuwsUfO0I-mX0QXQu4CABw&ved=0CD0QsAQ&biw=1673&bih=843

The box proudly displays "Made in U.S.A." even though Ronald used a British lathe!

I would advise against running one as it is difficult to find a small propeller. The smallest I had was 2", Ron fires these up with his custom made all aluminium job.

A 2 inch propeller is difficult to flick over with big fingers and it will run on a larger propeller but great care is needed to avoid a hydraulic lock. This tiny beast would not survive. Mounting an engine this small is also difficult - i had to make a special mount.

The larger engines .098 cc could be fitted out for glow and were using, as mentioned, a turned down Cox TD 010 head but the Nano Bee only has a a 2mm bore.

The smallest glow engines I have are 0.98cc and I have often wondered "Why not smaller?".

However, a glow plug can only be made so small - whether .049 or a 60 they are more or less the same size. Making glow plugs is difficult  and I can only imagine that the cost of specialty plugs would be horrendous.

When you are down to 4mm bore things get difficult.

For the .098s with 5mm bore the glow plug is a modifed Cox 010.

Here is a range of Valentine engines from .098cc down to the .006cc Nano

The Last Valentine Nano Bee Rv_tin10

Compared with a Cox TD010

The Last Valentine Nano Bee Rv_tin11


Lower than 5mm and there would be not enough metal surrounding the element.

Also, the recess for the element will affect compression and there isn't much volume to play with in one of these tiny engines.

Imagine the palaver shimming and deshimming one of these. Better off with diesel.

One day you will try diesel for control line and experience the delight of the aroma, the sound, the mess and the easy starting! That should give you PAWs for thought!

I think that producing threads this size is amazing but there is another element to it.

Assuming you have the tap and the die - the "screw" is so slender the process of cutting the threads must be time consuming and require patience with a steady hand to avoid breaking the needle.

Likewise, when tapping the hole, accuracy is paramount to avoid breaking the tap. Just getting the hole straight and true, prior to tapping, in those dimensions is not easy. The smaller the drill the easier it is to wander off course.

On the small engines - busting the NVA is my big worry. That is the most delicate part!

I wouldn't even dare try to start a twin cylinder Nano

Good to see some more of your collection Ian , If i remember correctly you have meet Ronald Valentine ? That is one big lathe to build such small engine but precise measuring is needed for sure and can only bee obtained with them . Small Cox Logo
