IHC Titan 50 HP, 2 cylinder Doug Kelley, European version
« on: October 16, 2021, 09:46:27 AM »
Hi Everybody,
during the past summer time I have done the design work for this model engine.
By the Doug Kelley design, published in the "Home Shop Machinist" in 2016, I have made a CAD model in Fusion360 with all the, for me necessary, modification to make it suitable  for metric bolts, shafts and some other here easier to purchase stuff, as piston rings.
At my favorite Greek supplier for Italian Caber rings I have found some 23 mm piston rings very close to the original design, 0,9"= 22,86 mm.
The gear design was a bit adapted to suit metric gears of the shelf, available in Germany.
In Luxembourg I have found the below shown fly wheel castings.
These castings do have enough material at the center to use "Sit Lock" clutches as at picture #4, a product of Switzerland.
To get an idea about the over all dimensions and the set up at a machine, I have printed the cylinder as a sample in 3D.
Also a metric design for a gear water pump was made, basic was a design made by Art Burns in the MEB magazine some year ago.
Here an animated design video of the very beginning of these project.

Hi Achim,
Looks like another great project to follow along with.

Cool!  I remember seeing that one in HSM.  This should be fun!  :popcorn: :popcorn:

Plenty there to give that new spindle a work out ;)

Those Flying wheels from RC Machine look quite good value for money

Achim,

I'm looking forward to your Titan build. 

The Sit-Lock hubs look interesting.  Which size or item number did you select for your Titan?

Regards,

Chuck

Hi Chuck,
it is site-lock 3 series , part number cal3 10x16

Hi everybody, thanks for popping in.


The fly wheel casting, d=154 mm,  are not so expensive EUR 29,00 each and they are partly machined already as shown in the picture above.
I have made a CAD model of the casting and a virtual  machining to fit the site-lock 3 self clamping set.
A CAD model is available at their site for download.
To hide this modern technology, was done by some simple pulleys  which will be bolted together with the screws of the site-lock clamping set.
One flywheel will get a pulley inboard for the water pump also.


Last two pictures my design of the already mentioned gear water pump with metric gears, very close to Art Burns design.
He has used an O-Ring for shaft sealing, I will try it with a small rotary shaft seal as shown in the picture above with the purchased parts.
Kind Regards
Achim

Achim,

Thank you for the Sit-Lock size information.  I found their online catalog.

Some other things, done here in last summer evenings.
Similar as the original drawings in the HSM magazine, I have made the CAD models some times started with raw part.
I.e., the crankcase.
As shown in the first picture, here are the parts with some overstock still  and bolted together already.
Than I have loaded the raw part assembly into a new file at Fusion and made the final machining there only, second picture.
Similar for the cylinder block.
The CAD model of the liner with some overstock at specific surfaces.
Than the first set up for hard soldering.
Followed by the fixture to do it.
Picture 5 shows the CAD model how it should look like for the soft soldering of the plate with overstock.
And last the cylinder CAD model with final, machining.
All these CAD models are separate available, specially to get the bridge to the CAM for all these first parts in not final conditions.   
If have tried to work her virtual very close to the order of the part making.
Kind Regards
Achim

After getting the crankcase done with all the manufacturing relevant models, the crankshaft and gear train was next for me to attack.
Crankshaft and bearings does match with metric 10 mm drill rod now.
The gear train does contain the metric modul 0,7 brass gears from Mädler now.
A slight modification of the gears bracket for the idler position was necessary.
Crank shaft and cam shaft position is still untouched.
Kind Regards
Achim

Hi everybody, some more virtual build preparation.
The brass miter gears are with modul 0,5, a metric gear set from Mädler too.
I have been not happy with the thickness of the flange, so my idea was to increase it by a sleeve, which will be added by some Loctite 648.
As shown in the second picture, enough material for a M1,6 grub screw now and no collision in the CAD so far.
The governor and its bracket does suit to metric drill rod now and all the story around the tappets, tappet brackets too.
I could not resist playing around a bit again with the Fusion 360 contact sets with lobes and tappets, but it does slow down the motion at the animation dramatically.
As seen in this video.
After this demonstration it will be switched off in the CAD model again.
Kind Regards
Achim

Hi Roger, first to finish the BME and hopefully in spring time I can start to make some chips here.
A bit is already done, I have just tried to make a small electric generator for this engine.
A Chinese 12V e-motor, slightly modified and hidden in an own designed new housing.
I will show the result soon.
Kind Regards
Achim
