Elmer's horizontal mill engine.
« on: December 21, 2014, 02:55:12 PM »
For my first try at building a steam engine I have opted for Elmer’s no33 horizontal mill engine.  To make it easier to do I have doubled the scale and adapted it to metric.

Shaft part of the crankshaft.

The crank pin

Setting up a piece of material for the crank web.

Drilled and turned the boss end.

Then turned around, and turned the outside and faced off.

The milling work has to wait until my mill is fixed.

Next were the eccentric, first faced and drilled and then offset to turn the journal.

Thanks to all for following.

The piece of stainless steel that I wanted to use for the valve pushrod had a slight bend in it so I had to do a makeshift drive arrangement to turn it between centers.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00010.jpgElmer's horizontal mill engine.

Once true it was chucked in a collet chuck for a bit more rigidity while turning.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00011.jpgElmer's horizontal mill engine.

Ready for milling.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00012.jpgElmer's horizontal mill engine.

Next was the connecting rod, here turning the radii with a form tool.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00013.jpgElmer's horizontal mill engine.

Turning done.

That’s all for now.

Well this is another project I will keep tabs on and keep my mind off my non working lathe. (Blown diode in the controller, waiting for replacement parts and hopefully it will be a simple repair.  :zap: ) Great work so far.

Next up were the 4 spacers for the crosshead.  Turned the outsides, drilled and cut off 4x.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00015.jpgElmer's horizontal mill engine.

Then set up a backstop.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00016.jpgElmer's horizontal mill engine.

And clean them up to the same length.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00017.jpgElmer's horizontal mill engine.

Then it was time for a cleanup as next I will be turning brass.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00018.jpgElmer's horizontal mill engine.

Turned the two main bearings.

Hi all,

The packing nuts were machined from hex stock.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00021.jpgElmer's horizontal mill engine.

The cutoff ends were faced and the holes reamed to final size.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00022.jpgElmer's horizontal mill engine.

Finished.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00023.jpgElmer's horizontal mill engine.

A piece of flat bar was centered to a punch mark.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00024.jpgElmer's horizontal mill engine.

A hole was drilled.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00025.jpgElmer's horizontal mill engine.

And bored.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00026.jpgElmer's horizontal mill engine.

The piece was then reset.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00028.jpgElmer's horizontal mill engine.

And faced, then flipped over and faced on the other side.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00027.jpgElmer's horizontal mill engine.

Ready for some milling work to turn it into the eccentric strap.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00029.jpgElmer's horizontal mill engine.

Until next time.

Hello to all,

   Hope everybody had a nice Christmas and Santa was very generous.

Next up was the valve chest and, as the mill is still out of commission, a piece of brass was fly cut to size.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00030.jpgElmer's horizontal mill engine.

It was then centered lengthwise,

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00031.jpgElmer's horizontal mill engine.

and the boss for the packing seal turned.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00032.jpgElmer's horizontal mill engine.

It was drilled and taped.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00033.jpgElmer's horizontal mill engine.

For the deep hole I had to make a long drill by soldering a drill bit into a length of bar.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00036.jpgElmer's horizontal mill engine.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00037.jpgElmer's horizontal mill engine.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00040.jpgElmer's horizontal mill engine.

Test fitting the packing nut and valve pushrod.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00041.jpgElmer's horizontal mill engine.

The part was then turned around and the boss on the blind side turned,

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00042.jpgElmer's horizontal mill engine.

and parted off.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00043.jpgElmer's horizontal mill engine.

The round over was done by file.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00044.jpgElmer's horizontal mill engine.

The piston pushrod was cut to length and threaded.

Tuning the pin for the valve pushrod.

Hi all,

Next a slice of cast iron was marked and cut.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00045.jpgElmer's horizontal mill engine.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00046.jpgElmer's horizontal mill engine.

A layout was stuck to the slice and some further cuts made. The off cuts will be used later.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00047.jpgElmer's horizontal mill engine.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00048.jpgElmer's horizontal mill engine.

The main piece was centered in the 4-jaw chuck,

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00049.jpgElmer's horizontal mill engine.

the outside turned to size and the gland boss turned.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00050.jpgElmer's horizontal mill engine.

Ready for drilling.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00051.jpgElmer's horizontal mill engine.

The left over piece had to be turned over and machined from the other end to make the blind head.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00052.jpgElmer's horizontal mill engine.

Being cut off.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00053.jpgElmer's horizontal mill engine.

To hold the blind head for facing the outside an ER40 chuck was used.  A slug of 25mm bar was placed in the back of the collet so it could close.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00056.jpgElmer's horizontal mill engine.

http://i519.photobucket.com/albums/u356/dozerd10/Workshop/Projects/Elmer33/Image00054.jpgElmer's horizontal mill engine.

Coming along nicely!  :thumbup:

The saw marks on the c/i, took me back to aching young muscles, in the apprentice school..... 1960.  :(

It's going to be larger than I first thought......  :scratch:

Nice work Abraham!  :clap: :clap:

Hi KRV and David
      Thank you for the encouragement.

Unfortunately the only means for cutting things in my shed is elbow work and a hack saw.

Hi all,

A question for the collective, with a CI cylinder what material would be the best fo the piston, CI, brass or mild steel?

I'd vote for CI.

Graphite containing, same rate of expansion as cylinder, less tendency to rust (with steam oil coating) than steel (for steam), no tendency to electrolytic action with cylinder. (as brass would, if damp).
