I somehow missed this thread.
Thanks to Paula for the great information on D&M.
I wonder if our resident historian aka Gil has any information to add.
This is really a wonderful engine Nick. Another successful road trip!

One thought I had... You mentioned about it not needing a cast base, as the crank was high enough for the flywheel to clear. It seems doubtful to me that an engine with separate bearing supports would have been designed to be mounted to a wood base. That would be an open invitation to bearing misalignment from the wood moving over the passage of time and temperature/humidity changes. In addition, the flywheel looks small for the 2" bore size.
Could it be that this engine was pieced together from parts of one or more incomplete engines? If a cast base was lacking, perhaps they used a smaller flywheel to avoid the need for a recessed base. (Attachment Link) Just a thought. Practically speaking, the wood base should work pretty well, as long as the bearings are not too close of a fit.
I am only going off that Jim and I have the only 2 I have seen of this engine, and would love to be proven wrong. If another appears with a cast base, it would be quite easy to get another couple made for ours… I will point out that the Stuart Beam is sold with a seperate support ;)
I thank you a ton for the D&M information!! Even if it’s not the maker of our engines, it is great to learn about one I had never heard of! :)

Nick, that's one bruiser of an engine (and one very cute boy!)

A little more about D & M Model Engineering...
Two model engineering enthusiasts, Duane Dehnicke of Western Springs IL, and Ed Miller of Merrimac WI, started a hobby supply business Known as "D & M Model Engineering". Not sure when they started, but I acquired one of their 40-page catalogs (3rd edition) in 1986. They sold casting kits, plans, books, steam fittings, bar stock, fasteners, tools, etc., pertaining to the model engineering hobby.

I met Duane (the guy on the left) at the NAMES show sometime in the late eighties. A nicer, more helpful person you could not hope to meet. He was a police officer in his full-time job. I never met Ed. He was much older at the time, and I imagine he's gone back home by now. Duane is in his eighties, and still selling model engineering stuff, though not as a regular business. He has a few items for sale on the Live Steam website:

If I had more money, and more time, I would buy one of those power hacksaw casting sets, just for the fun of building such a heavy-duty little tool.

I honestly don't know if D & M sold any other sizes of the 1/8 HP engine. It's certainly possible. After I built the 1/8 HP engine, I shifted my focus to IC engines, and lost track of D & M. In any event, your engine is an impressive specimen in its own right, and could be made into something really special.

Heck, it might even be too heavy for me! ;c)

Seems like that brazing rod's indented lettering would be a little hard on a packing gland ..... kinda like a file?!?!
Haha, true!
Pictures don’t really help show the size of it, I asked him to hold it, but it was too heavy for him 😂

Grade 5 bolts were also used throughout, making me believe it’s not as old as it looks. The more you look at it, the more the wonderful paint job falls off :D

They also used a brazing rod on mine, you can make out “anaconda 997 low fuming”

Paula,
Absolutely beautiful work. I can certainly see the family resemblance between your engine, and the one that Nick picked up, in that the valve chest is held on by 4 studs in the corners, although Nicks is much larger (I am guessing 2" bore like Mine). Mine is of course different because the cylinder and valve chest is fabricated rather than cast.
I wonder if the larger ones such as Nicks or mine are pictured anywhere in the catalogs or literature.
Jim
I searched all over mine for casting marks but can’t find anything other than the number 13 and 11… This guy on SmokStak mentions his had D-M cast into his.
https://www.smokstak.com/forum/threads/d-m-model-engineering.35752/
I also wonder if our larger ones never had an extra aluminum base like the smaller ones which needed it because they’re recessed for the flywheel.

Thanks all!! I have been hinting to Bruce since he got the Sipp to let me know when he moves it on :D
Great Road Trip Nick!
Let me know when you make your next road trip Charlie, would be fun to meet up with you and whoever you end up visiting! :)

Jim, I'm glad you linked that video! The reason is that I was getting ready to chime in that I believe that the "D&M #11" must have been a copy of the 1/8 HP version that Gil referenced as being from American Model Supply. I uploaded that video to YouTube a few days ago. Here is the page from their 1986 catalog:

This is the set of castings that I purchased:

Here's some pictures of the finished engine:

I believe that the AMS engines may have also been the inspiration for Anton Bohaboy's 3/4" bore version:

Nick,
I am really glad and excited that you got the red one (and the SIPP of Course, since I know you have been looking for one). I am doubly excited, because I will probably get the chance to see both of these in person some day.
This popped up in my YouTube feed a couple of days ago. Looks like the same engine manufacturer as yours and mine, Although of course mine has a bar stock cylinder rather than the original casting.

Here is the Video Description;
This is a short video of my D & M #11 steam engine, running on air. I machined this engine from a set of castings purchased from "D & M Model Engineering" back in the 1980's. According to the catalog description, this engine is a reproduction of a line of steam engines that were available from a Chicago firm in the early 1900's, and long since out of business.
The bore is 1", and the stroke is 1-5/16". The flywheel diameter is 4-1/4". Main engine components are of cast iron, with bronze connecting rod, eccentric rod, and slide valve. The sub-base is cast aluminum. The engine is equipped with a Stuart displacement lubricator, and Stuart globe valve.

Wow Nick ..... I'm sure it was worth the miles!
That beautiful 1/2 horse Sipp is really something and I'm sure you'll be beyond pleased. Heck, it looks to have all the whistles and bells (well, gauges anyway) that you could ever want.
What that other big bruiser is I know not, but it certainly has the appearance of a real workhorse too!
Hope you have a boiler big enough for those monsters, though I'm sure you have an adequate compressor to do them justice.

Great Road Trip Nick!
I am sure you enjoyed your visit with Bruce. He has a dream workshop.
-
Congrats, Nick! You have acquired 2 great additions for your already great collection.
Great to see that 1/2 HP Sipp find it's way to another great forum member's home.

It was fun having you & Jacob visiting for a while Nick. I know the 1/2hp Sipp is off to yet another good home where it will be loved.
-
Great looking engines Nick, definitely a good find, and your son sure looks like a very happy little boy having fun spending time with Dad. Well done on both counts!

I had a good co-pilot with me for the 1382 mile round trip and he loved his short time at the big lake even though it was very cold and we were the only ones out there :D

As usual, I had plenty of fuel to get me there and back ;) :D

Many of you will recognize the 1/2 HP Sipp, it has been through the hands of a few forum members… Gil, Scott, Charlie and Bruce that I know of :) The red one however is unknown to me… I had already been planning to head to IN for the Sipp and then the red one popped up on ebay over on the other side of WI, so it wasn’t too far out of my way. ;) I knew it was big because @Quickj brought his to a show we display at and it was coming from a good seller. I also had a great couple hours visiting with Bruce and wish I had the opportunity to meet up with forum members more often…
