Horizontal Stirling - Terry Coss design

[David Morrow]

I'm mostly following the plans from HSM Nov/Dec 2005. I've sort of pimped it up a bit though. The column may be shortened a bit before it's done.

I've been playing with anodizing and have been quite happy with the quality and the ability to add some colour to my projects. I think this one will be a mix of black, red, and raw brushed aluminum.

Ignore the brass cylinder on the right - it's a part for another project and is just there to hold things up.

Nice work Dave. That is a popular engine to build. I've seen several of them at shows. My attempt(s) did not run well but I was quite new to this hobby at the time. At some point I'll go back and do some tweaking. Meanwhile good luck and success in your build. I really like the staging you've built :bow: :bow:

Cheers,
Phil

Very nice, David. I've gotta give that anodizing a shot some day. How finiky is the process?

I bought my gear a couple of years ago and sort of put things off for a long time fearing all the fussy details. In the end, I just made up my own simple checklist of steps and it's all very simple and easy.

1) Clean well
2) Anodize for 1 hour in mix of 1/3 battery acid & 2/3 water
3) Rinse well in clear running water
4) Dye for 15 minutes
5) Rinse again
6) Seal - I put mine in a kitchen sieve over boiling water using steam to seal for 1 hour.

I bought the power supply & chemicals for about $400 or so from:
http://www.focuser.com/atm/anodize/anodize.html

I bought 5 gallons of battery acid locally for $25 or so. I only used 1 gallon.

Here's an example of a clock I designed - it's just the body, the picture was taken before I put in the clock insert which is about 2" diameter.

I should probably make up a page on my web site with some very simple anodizing details.

I didn't think it was too expensive when I considered that I probably had a power supply that would last a lifetime and dyes enough to last 5-10 years or more. And it isn't nearly as messy as powder coating.

I've been busy making a mess in the workshop and thought it was time for an update. Usually I document my projects on my web site at :

There is still a ways to go, but here is what it looks like so far. I've taken some liberties with the design.

David,
Thanks for the photo of your progress :bow:. It's virtually unrecognizable as a Terry Cross design and I built one. Can't wait to see the finished engine

Cheers,
Phil

Update on the Coss Horizontal :

One small part, a couple of spacers, set screws, and a tune up away from finishing. I hope. I haven't figured out what the colour scheme will be yet.

Progress to date:
