    Hi after a few days deliberation and looking through plans i have decided to build an Epicyclic Steam Engine designed by Bill Reichart.
    So far i have just about finishes solid modeling the engine an all seam well, as i go along i will be adding some touches of my own and have fiddled with a few things in the design already , cant help myself. I hope to make a start on the build in the next few days.

    That looks like a great engine. There is a very similar engine which is displayed at my local club, but it's called a "hypercycloidal" engine. Has exactly the same crank mechanism... Hypercycloidal sounds better IMO.

    Good luck with the build!

    Rob,
    Very nice! Now, give up the secret....How did you do those outside radii in the corners ???
    Rotary table?

    Hi Tony , no secret, CNC ,getting rid off the radius corners so i had square corners took the time.

    Please provide chapter, paragraph, and section number of the offended rule. ;D

    For that matter...please direct me to the tome of rules so that I may educate myself. I certainly don't want to break any rule of this very august group. :big:

    Zee,
    If we let Rob get away with CNC the next thing you know he will be engraving his initials in fancy script and all kinds of fancy "Victorian" stuff on the engine. Being a fellow hand machinist I thought you'd have my back and help me make up some rules Rof}

    Okay Rob.... you can use the CNC, but you gotta to keep your eyes closed...(grin). This is an engine design that is steadily rising on my build list. Looks like your project is going to be a "must watch" here.

    Ah...yes yes...you're absolutely right. Apologies.

    Rule x: When making 'period' pieces one should be limited to 'period' tools. :)

    Rule x + 1: Only 'social' rules really matter.

    Rule x + 2: Don't listen to 'Zee'.

    Rule x + 3: Did I mention 'don't listen to 'Zee'?

    Rule x + 4: Thread detours okay. Thread re-routes not okay.

    Love this forum. :big:

    While typing this I see that 'Cedge' advocates breaking 'x'. Shame shame shame.

    Hypocycloidal, not hypercycloidal.

    Sheesh, what am I going to do with you guys?

    epi - outer, outside (think epidermis = outer skin)
    hypo - inner, inside, under, beneath (think hypodermic = under the skin)
    hyper - excessive (as in hyperactive or hypertension)

    Rob, I bet you are the man who could answer this.

    I haven't been able to find any written reference that answers. The oldtime original alloy called Brass and the one called Bronze. Was it strictly adding tin to make Brass and Zinc if you wanted Bronze?

    Cheers Philly :)
    Very close Kermit you just have it the other way round, copper + tin = bronze , copper + zinc = brass
    Cheers Rob

    It's an old feeling I haven't had in such a long time.

    feeling like a kid in school afraid to ask questions because I even get those wrong... :p
