Arch Bridge Construction

Hi Terry,

I appreciate it that you are going to follow along.  Hope it works out OK.

Steve.....

That Unimat is the first of the later model.  You have me by about a year.

Regarding belts...........Don't pay anyone anything for them..........

Go to a good hardware supply or automotive supply and get neoprene O rings.   I think the larger one is a 3 1/2" by 1/8" and the smaller one is a 2 1/2" by 1/8".

They don't need the twist band that they originally came with nor do they need some trick this or that.

This is the 1960's........... things just weren't that complicated then ! ! ! !

Regarding learning stuff on it...........  Just get out there and start turning stuff.

It can be used as the following: common lathe, drill press, verticle mill, horizontal mill, a dremel with a cut off wheel can be set up as a horizontal post shaper......... and a bunch more.

Hopes this helps

see ya

This is going to be an incredible looking bridge.

Here is the latest progress on the bridge.  I am in the process of fitting the diagonal bracing to the bridge.

Following along with interest; I have a steel deck truss to build at some point.

Fantastic piece of engineering, Steve. Wonder if Central Valley wants to license your design to make a new kit offering....

Steve,
Very impressive progress on an ambitious project. I'm late to tag along, but glad I did. Your method of attaching the bents to the jig is genius.

Attached are progress photo's on the arch bridge.  I now have to fabricate and install gusset plates where the members come together.

Hi George,

Thanks for stopping by.  I can't take all the credit for the jig.  But I modified a jib found in a Model Railroader bridge construction manual.

Great looking bridge.
