Making a Wood Beam Engine

Gerhard Olivier:
Hi all

I have moved my workshop to a small attic and it is above work - This means that I have a lot less shop time.  This build will probably take some time.

Decided to build a wooden beam engine 61/2 inch flywheel with a metal band on the circ.  The cilinder I want a smallish bore and a long stroke so it can go very slow??? 
I decided to make a occilating ratary valve on a eccentric?  Main material is to be Mahogony and brass and some bits of cast iron.

The timber was cut to right thickness and then shaped on the fretsaw All the pieces of the flywheel was done first.  Then the outer rings glued on the miters with super glue.

Thanks David, Saw

Just the last bit of todays progress.

I found a piece of 6 1/2 inch cast iron pipe 1/2 inch wall 500 mm long in the scavinging jard With a lot of efford managed to cut a chunk of the stuff off It really is to hard for my tools,
This fit over the outer edge of my 5 inch chuck .  Bored the inside as big as poss to allow 5mm ring cleaned cast iron.  And parted of a 18mm wide piece.






On the mill I put a big piece of 18mmPlywood on the RT and mounted the wooden rings - Then I cleaned the outer edges to the same size as the hole in the cast iron - this hole was cut 6mm into the plywood then the ring was used to hold the pieces in the same place and clamped the outer edge to clean up the inner diameter.







The same setup was used to mill the centre piece with the spokes. the spokes are 10mm *10mm so on one end the the spokes had to be reduced as well.  The centre of the hub was bored as the same setup as that keeps it concentric.



That is as far as I  got today - the fly wheel needs sanding and glueing ( epoxy between the rings - with the joints staggered) Hopfully the epoxy will keep the ring in place.  Traditionally the ring would be made to small and the heated and placed while bigger and crimps onto the wooden wheel???   Im not going to try that at all.



Hope this is not to far from the madmodder ideal!!!!

Very nice.

Watch it or this lot will have you making replica wheels for a Stephenson's Rocket.
