Hi
I have posted some pictures of this engine in my "casting brass" thread.
I thought it would be a good idea to do a build log of this engine.
I share my shop with a good friend , so any rough bits are his work

This is the basic speck of the engine
Bore 1.875", Stroke 2.000"
Rated 2hp
400RPM 120 PSI
Stephensen Reverse
Double Acting V twin
The drawings are imperial desighned to be built without castings

The base plate milled out of 10 mm plate (drawings use 1/4 but i had this to hand)
Using thicker plate caused some problems later.

Getting the base plate & back plate at 90 degrees proved difficult
I will find some of the early pictures & post them

As this engine is about half way built the build log will be in fast speed

This is how it should look
Cylinders were made from 2 large pices of steel (to do it again i would cast bronze)

Had the old bantam lathe working hard

Tomorrow it will be the steam ports

The valve ports were machined on my Axminster mill drill . This has been replaced by a Warco 626 mill

Hi
I found some more pictures of the con rods these were turned from 1 inch key steel the big end journal being screwed and silver solderd

All the bearings are ball races as this is a working engine not a modell

I am trying to get a hard drive to work as most of the pictures are stored in there
Regards
John

Hi John, appreciate your sharing pictures and some of the build log with us, particularly on a working engine, as those are all to seldom shown on such a forum, or should I say so seldom done at all, given the ease of just buying a small engine made somewhere else. I am impressed with the numbers, 2 hp at 400 rpm, you are looking for a good bit of torque out of it, I hope it turns out without too many irritating bits and pieces. I'm definitely looking forward to seeing it run, it looks like a good start.

Hi
After a bit of a traumatic family time i have eventually motovaited my self in to finishing this engine.
After meeting Rob Wilson i am converted to casting

The drawings ask for the trunk guides to be fabricated from iron pipe , bronze castings will be better

This is my first attempt at propper pattern making (i dont like wood)

Some pices of MDF glued together

All turned up and primed
Plenty of rubbing down later

I must admit i am very pleased

Now for the core box

Same again MDF (magic wood) glued together boring the hole was interesting

It turned out better than expected

John.
Those pattern parts look almost as good as Rob's.

..... But, he's had more practice than you!

Blummin well done!

Great Video John, very interesting to see the casting proses, especially the one that went wrong it helped in the understanding of the technicalities of the proses

Thanks for showing, look forward to seeing more.

Stew

Hi guys, you really are getting a great finish on the casting, brass isnt the easiest of stuff. Well done!

Brass_Machine · « **Reply #20 on:** November 07, 2010, 07:32:28 PM »

Hello John, I can't say I've enjoyed a video more than the very professional looking operation you and Rob put on with this casting. The finish on the good one was great, clean, and should do you well in your engine, and the one with the sand a bit moist was very instructive, particularly that you immediately noted problems and stopped before a mess was made. It almost looks like it was done deliberately bad, just to make a good show on what to do when it goes wrong. I hope to be doing some casting of the same sort in the not too distant future. It really makes it all to have the whole of it, from the ramming up, ramming the sprues, carving the pouring funnels, all the way from beginning to finished casting, laying on the ground, looking ready for turning, and then turning. Fine piece of work there, with the video, and well complimenting the work on the cores, boxes, and patterns. Truly instructional

What kept the core in the center of the mold cavity?

doubleboost · « **Reply #26 on:** November 10, 2010, 05:09:18 PM »

The pattern has extension peices (core prints) the core just rests in these
