the machining and components was above my expectations the only work needed will be in the cam shaft tunnel to remove a very small amount of material where holes have been drilled the heads and exhaust are great I look forward to running this masterpiece thank you

The kit was simple and great fun to assemble! The instructions were easy to follow and fun to use, big clear color text on good paper. Engine went together easily and ran great, balanced, smooth and better than Retrol's promo vid. I got this from a different supplier, but I support EngineDIY as well, great retailer.
Great engine in the tradition of European steam toys of a century ago, lots of working functions and value and LOOKS AMAZING. Thank you RETROL.
The ffedback from steam engine buffs on my Youtube Vid is AMAZING, they LOVE it

I have bought 2 of these as Christmas gifts for 2 clever little boys. The kits are well packed and instructions appear simple to follow but as yet, unopened and unassembled.
If these as good as the assembled engines I will be very happy, in the days after Christmas we will know. I have no doubt we will be back for more
Thanks to the staff, communication was excellent< Thank you

Absolutely love this little engine the details are incredible

I am stunned. I did not realize that this engine had been increased in size to almost double its size when I ordered it up. I thpught at first there had been a mistake made, but to my delight after investigation, read there was no error made. This engine is truly a work of art. It is a brute to be sure. I was very surpised that the exhaust pipes were 3D printed instead of formed of metal. I have yet to decide how to best mount this gorgeous piece of work. The quality is outstanding. Some research has been necessary as to running as the supplied manual, although illustrated and states various specifications, does not really delve into specifics. I wish that it came with a generator to fill the hole that is very apparant on the forward part of the crankcase... I am delighted otherwise and can assure others this is a true find in terms of realism and value.

Great to show younger kids the mechanics of things
By building and seeing it work.

Haven't hooked it up yet, but the craftsmanship looks amazing.

I enjoyed building the sterling engine. All the pieces were nicely cast and cleaned up for assembly. The instructions were nicely done and easy to follow. The only difficulty I had with the instructions was the amount of wick stick out.
It came with a few extra parts which is good because I lost one small rubber washer. It is hard to put it on the rod with your fingers because they are huge compared to the tiny rubber washer.
I may take it apart and paint a few of the cast pieces. I will be adding my own belt / small motor so I can light up an LED.

briliant

Very nice and it runs. I wish the ignition timing was easier to set.

Arrived today, well packed. Beautifully made model. Not started yet but oiled and greased where required. Thorough inspection to check everything. All good so far.

fits perfectly

This engine boiler kits is beautifully engineered and makes for perfect gift! I am very happy with it,The craftsmanship is impressive and it runs smoothly.It's a great addition to any collection or a fantastic starter piece for someone who appreciates aquality

Everything went smoothly, fun build only issue I ran into was the hood doesn't want to stay closed but I can live with that
