Pumped diesel furnace burner
Just a quick lash up to test my ideas on a pumped burner system using a mini gear pump to feed pressurised diesel to a standard boiler nozzle.

Rider Ericsson 1/8th Scale Hot Air Pumping Engine
Переглядів 2,3 тис.Рік тому
Construction of a 1/8th scale Rider Ericsson Hot Air pumping engine. Originally produced in the late 1800's for domestic water supply. The water pumped also served to cool the cold side of the cylinder and improved performance. Any form of heat supply coal, wood, gas or oil but this scale model runs on a spirit burner. Constructers in the USA can purchase castings but these are prohibitively ex...
Horizontal Twin Cylinder Steam Engine
Переглядів 24 тис.2 роки тому
My second steam engine and is a slightly modified version of a design by Julius De Waal. The plan is available free online and is one of many designs by JDW. I revised the eccentrics to make it easier to produce and added a hatch on the valve chest to make timing of the slide valves easier. There are a few errors on the plans but not insurmountable to resolve.
DC Sabre (1.5cc) test run for auction
Переглядів 653 роки тому
This is my DC Sabre originally from mid 1970's which I have decided to auction so a test run was in order. Many parts are not original (NVA assembly, Prop driver and comp screw) but she runs and can still be flick started. Video for Ebayer's benefit.
Clanford Clan 0.24cc Aero engine
Переглядів 5604 роки тому
My first two stroke aero diesel engine and I picked a tiny one! Although quite challenging it was a very rewarding build. Small engines like this can be troublesome to start and run so I was greatly rewarded when this one did run! I admit that I cannot get a really smooth note from it but I do not intend to fly it so I am well happy it at least runs.
Gerry's Beam Engine
Переглядів 12 тис.5 років тому
I started this project well over a year previous and finally got around to finishing it.. The plans are freely available and the designer is Gerry Dykstra aka OldBoatGuy on the HMEM site. I chose to use casting methods with machining to utilise recycling scrap plumbing as the material. even machined parts were from cast bars of the same. The only purchased Brass stock was square bar for the cyl...
CNC router
Переглядів 3588 років тому
This is a project that I originally started over a year ago and finally got back to it. It is very (cough) similar to the Blue Chick design elsewhere on the web and uses chain drives for translation and a power screw on the Z axis. It still needs some work but this is an early test run to establish feeds n speeds etc.
Vega V Twin Aero Glow Engine
Переглядів 3,6 тис.9 років тому
This is my version of the David Parker V twin model aero engine from 1986 issue of Model engineer. Capacity 9cc. Approx 100 hours work machining from stock material and countless hours to master I may add! There are still carburation issues to sort but otherwise a finished project.
Vega V twin trial on one cylinder
Переглядів 4809 років тому
I have been struggling to get my Vega running so decided to concentrate on one cylinder at a time. I am now certain the problem is intermittent leaking of the valves so these need re-working.
Hit and miss Kerzel engine..finally finished!
Переглядів 4,3 тис.10 років тому
Finally, after more than 18 months of on and off working on this project, she is finally finished. Flywheels are home cast aluminium with lead rims and capped with stainless tyres. Main housing was crude cast and machine finished for with cast iron liner. The original cast iron piston and rings were temporarily replaced, whilst playing with compression ratios, with an aluminium version and a vi...
Stirling 60 - variation
Переглядів 2,2 тис.10 років тому
This is my version of Jeroen Jonkman's Stirling '60' engine. Jeroen kindly offers his plans free and you can find them at www.machinistblog.com/free-plans-jeroen-jonkmans-stirling-60-2/ I decided to make a single tier version and found an excuse to finally cast brass for the base plate. not perfect but I am more than happy.
Brass Casting - 2nd attempt
Переглядів 40710 років тому
My second attempt to cast a brass base for my Stirling engine project. I did not record the first disaster. Not a perfect result this time either but workable and encouraging. By up-ending my home made kiln I managed to create an electric furnace and get to 1000 deg C in around an hour with a 1kg melt load. I really need to get my pouring shank finished for the next run though! Apologies for th...
Kerzel Hit n Miss Trial
Переглядів 2 тис.11 років тому
After months of trying, I am finally getting this model engine to run, albeit for short periods! Before finishing the project I needed to know if it would run and it has taken considerable time finding all the variables that can stop it actually running. It sounds Hit and Miss even though I have not fitted the governor mechanism so there is still work to do. When it does run reliably I can work...
Hi does this come in a kit. Rudy
No. It was all scratch built including the castings by myself. The plans for the bigger 1/4 scale version are on my GrabCad site. There used to be a supplier of the castings but not available in the UK
nice :)
Beautifully made love it
Thank you 🙂
❤😊
Excellent work! Utterly beautiful! This may be my next Blender 3D build :)
What a job !!!!🙄 Congratulations 😉
This is different, good👍👍👍
Awesome👏👏👏
Very good job sir ...awesome👍👍👍👍
Good job sir....
Very very good👍👍👍
Very nice👍👍👍
Very good job...
I want this, give your no.
Good job, love from India🇮🇳
Thank you 🙂
i need it
it's so cute
BEAUTIFUL
Thank you 🙂
Very well done. 1/8th scale of which original pumping engine? What's the beam length on yours model?
Thank you. It's based on the Ericsson 8" version so my working piston is 1" dia. The beam is 98mm long centre to centre.
@@creast56 Very nice. Unfortunately the casting kits from Myers are to heavy to ship to UK at an economical cost. I'll have to work something else out.
@@rogtallbloke Yes, as I mention above, it is too expensive to ship from USA which is why I did my own castings. It was quite an ordeal over many months.
I want to buy it
This is fantastic! Xxx
Amazing job!
this vid bouta blow up
Bro about to get 5 m views
Awesome, glad to catch this video before it blows up.
Nice job, it's a great runner!
Thank you 🙂
Nice one Creast. Merry Christmas buddy.
Hey Foss. Merry Christmas to you too! 🙂
That was fast and quiet cutting 👍
Very nice work. Runs great.
Thanks. I did pick quite a complex project for my first aero engine! Was satisfying to complete it.
Not much aluminum in cans. Try going to an engine shop and asking to carry away old pistons. They make great castings for model engines. Used transmission cases are also good.
It was just a bit of fun. Not serious. I do my regular castings from cast alloy wheels and other scrap cast parts. :-)
Hola como la hizo los materiales?
That's awesome Rich. Did you make it all form scratch? You do some anodising?
No its not a home build. I bought this in the 1970's and lay in pieces for over 40yrs and some parts were lost. So I did remake the needle valve assembly and compression screw and re-anodised the red parts that had gone pinkish. Now sold. Hope you and family are well! Cheers Rich
I want one of these engines for my work station where can i find one?
Hmmm. Tricky. You don't see many of these for sale as most are made by enthusiasts like myself. The original factory made units suffered a spell of bad engines that didn't run but how many still exist is beyond me. Sorry.. mine is not for sale.
creast got it. Would it be safe to run one of these in my office or it emits a lot of smoke?
@@jamzempire Errr :-) it emits some smoke but mainly unburnt castor oil vapour which is very sticky believe me !!
creast lol ok i dont want that in my office then ill find something else. Thanks a mil!
Deep respect my friend..very nice job!!! sweet run.
Many thanks. It was a very challenging first 4 stroke aero engine. I don't make things easy for myself do I?
Sure not!! But the reward is then even sweeter when t finally runs after so much work!!! Really, a very good job my friend!!
..the first diesel?? boy oh boy.. I am impressed!!! even it is not reving a lot..but finish is very nice mate!!.. really thumbs up for you!! .. I guess a timing issue..BUT.. it runs!!!! congrats on this build!
Many thanks!
Muito bom!!
Very nice!
Hey Rob! Thanks. Hope you are keeping well. Rich :-)
Do you have drawings and plans
Nice engine, it just saddens me to see a modification, to a Chinese copied US machine
Not sure I understand your comment re: chinese copied machine? I know you can buy these type of engines online but in constructing one yourself has the benefit of the journey (and pain) and not the destination :-)
Good looking engine, runs great.
Answers to your questions, 1. oil feed is pressurized 2.I need to preheat with propane because I use a heavy oil.3. It is a cone or half venturi and I don't have a clearer picture. Best of luck getting a siphon nozzle working.
Thanks for the info. My burner is running very well but I have to put up with the noisy compressor kicking in all the time. Not sure if it will do cast iron but then again I don't think furnace would survive well at that temperature. Cheers mate.
The flywheels are cast aluminium with lead filled rims capped with stainless rim rings all to increase mass.
Cast iron for cylinder liner and steel for the crankshaft. Some bronze was also used for bushings. Silver steel ( drill rod ) for pivot pins.
it runs better than mine, not sure if both cylinders firing as one is cool. like the way you did your carbs, seems to rev. up and down well not sure why you are unhappy
I am not sure what you mean by both cylinders firing as one??? As for the carbs, it didn't respond as snappy as I would like and after running each cylinder separately I knew there was more potential response in there.
Really nice build of the Vega. It looked in the video that you used aluminium for the cylinders instead of EN8M as specified? I had thought about doing that, but I couldn't see a cast iron liner in your version. Be interested to know if you managed to resolve the carburettion problem or if you have flown this motor.
Thanks for your comments. The cylinders do have Cast Iron liners as I didn't have much success doing DIY case hardening on the first steel versions so I went more traditional. I did improve carburation but have not flown the engine. It would be a travesty to crash it :-). It now sits on a display unit.
is the crank on the crankshaft balanced..???
+Floris Borremans No it is just made to the drawings and the flywheel is so big in comparison it hardly matters.
Nice job creast!! What did you use for the ignition system? I'm getting ready to build one of these engines and looking for different viewpoints. Thanks Warren
Hi Warren, It was a long haul for me to get the ignition small enough to fit in the base and be reliable. I ended up using the HT supply from ot40.com/cdi_ignition.htm but not the PIC based trigger system. I wanted to use a hall effect switch triggered by a magnet on the cam gear. The HT coil was home wound and is based on that used on Jan Ridders Blokker circuit (ridders.nu/Webpaginas/pagina_blokker_vonkcircuit/blokker_crcuit_frameset.htm). I did try his original circuit but it was not suited to the Hall effect switch which won't work on 1.5v. The blokker coil is fine but too much soldering can loosen the terminal legs so I wound my own. I also used some circuitry to just deliver a quick pulse to the thyristor so there was no chance the coil was permanently energised. For testing purposes I started with a car coil but that is almost as big as the engine!
creast Thanks much. I will have a look at the information.
Nice video Creach don't know why I've not seen it before. 54 cans found as litter! Come on admit it probably just one good nights worth. LOL Hope you and yours are well.Best wishes Fozzy
A thing of beauty creach well done. hope your well. Fossy
Hey Fossy.. many thanks. Trust you are well too :-)
Cool little rig. I gotta ale one sometime
Thank you. Glad you like it :-)
