Very nice Chris, would it help to flycut the top of the letters to make them stand out more?

Hmmm, maybe.... the lug on the back is tapered slightly, but I could drill/tap it for a better hold. I'll probably start with some sanding and see what it looks like. The original was painted black with the tops of the rings/letters painted gold, have not decided whether to do the same or to leave it bronze. Though, now that you mention it, if the relieved surfaces are still the rough, and the tops taken smooth and polished, the bronze color would pop... Could just clear lacquer it to keep it shiny...

That looks great - I really like the fine adjustment on the one leg of it, have not seen that style before. Those come in handy on woodworking projects too. How did you make the hex holes in the uprights to take the crossbar? Also, does the adjustable leg have a lead holder or something on the top, or is that the handle to hold it while it pivots? Very slick design.

Tooling & Machines / Beam Compass we called them Trammels
« Last post by sbwhart on Today at 07:34:58 PM »
Over the week end I made a Beam Compass or as we use to call them Trammels but I thing Beam Compass is a better description as the man said it does was it says on the tin.

Your probably wondering why I needed one of these old fashion drawing/marking out instruments in the modern days of cad. The reason is quite simple I need to draw large arcs in order to model the valve gear on the loco I'm building and my little lap top was just too small to be able to see what was happening so it was a mater of good old pen a paper to the rescue.

it can be a tricky thing to measure - out of round with constant widths as it can occur with different numbers of nodes.  I've never done it, but recall  the test is to rotate the work in various V blocks that have different angles to ensure its not lobbed.  In other words a 90 degree V block test is not conclusive

I'm surprise this happen if you lapped it; you're using a split lap?

It has that special rarity value as it is one that I am actually letting go of, there are not many of those ;)

Well, if this one has had a proper amount of casting-fondling done to it, it should be quite a valuable collector item!   :Lol:

This afternoon the casting arrived with the boiler front nameplate from the Lombard Log Hauler up in Maine - the gentleman who made the pattern and cast the one for the restoration of the real one kindly agreed to cast and sell me a bronze copy of it, came out pretty nice.
For size comparison, here is the one on the real machine (someone put a silly model in front of it!)

and here are the spare ones I had photo-etched for the model:

And here is the casting he did for me, with the photo-etched ones in the lower left for scale, ready for some final cleanup and painting:

The back has the name of the museum, nice touch:

So, after some casting fondling (hope I don't have to send it to Jo for some professional casting-fondling time), I'll get the edges filed/sanded smooth where the gates were, get it wire brushed clean and painted. Should look wonderful with the model!

Are you planning to live long enough to make a model of this, or are you going to pass it on to your children and grandchildren----and maybe even your great grandchildren?

 :ROFL:

Hi Brian,

Its definitely going to be a long term project, even by my standards (finished the Shay and Lombard builds in about a year each). I am figuring this one to be about 2 or 3 years, give or take a year - its a SLIGHT help that two of the four steam engines in it are identical, so that will save a few weeks!   :o

I love this kind of project - like you I really enjoy the build, and this one has LOTS of new shapes to figure out how to machine. I am hoping to take things up another notch in the level of detail, always learning new techniques. Given the size of the boiler, I'm not sure if this one will be practical to run on actual steam, or if it will rely on a compressed air line running in. The boiler on the real one  is fairly small compared to the ones on locomotives, and depending what scale I build (something around 1:16 is current guess) the boiler could be too small to run four engines, the main engines are quite large bore/stroke let alone the slew/crowd ones. The NPS guys were very surprised at the size of the boiler, but it obviously was enough for the real machine, it was used for over 40 years.

I really like that setup with the cart!
