Design Replicated from the General U.S. Grant Bridge Fullerton - Portsmouth General Plan. The Dravo Construction Comapny Designers and Building Engineers Works Department. Pittsburgh, Pennsylvania. Approved Dec. 14, 1926. Drawing No. 17110
Construction of the Ulysses S. Grant Bridge began May 26 and was completed August 27 at the cost of $1,000,000. The Bridge was dedicated August 22, 1927. The Ulysses S. Grant Bridge, eligibal for the National Register of Historic Places, was designed by Roger Robinson and David B. Steinman, 1887-1960, one of America's most respected bridge designers, incorporated unusual engineering feautures into the design to compete with the Cantilevered Truss commonly used on Ohio River crossings. The bid came in 10% below the lowest bid for Cantilever construction. The unique cost saving features included, Rocker Towers, Prefabrication of Cables, Sand filled anchorages and a continuing stiffening of truss. The bridge was fabricated and erected by the Dravo Construction Company with supporting design provided by the J.E. Greiner Company . The Main suspension span measured 700' and the two side spans measured 350'. Two 111' steel towers mounted on concrete piers supported the cables. The upstream and downstream cables consisted of 486 wires each. The Continuous Truss, A Warren Pony with Verticals, measured 14' in depth. The bridge functioned as a toll facility owned and operated by The Portsmouth - Fullerton Bridge Company until 1957 when purchased by the State of Ohio. The family of Ulysses S. Grant was said to have operated a Tannery on the Kentucky side of the Ohio River where Ulysses S. Grant spent summer vacations working as a clerk.

Here are our failed attempts to partially self replicate using our CNC RepStrap with ABS.
We still have problems with the heated M6 rod plopping out of the PTFE part. Marius had the great idea to wrap around some PTFE tape around the M6 rod before screwing it in to increase the friction to prevent it from popping out. This seemd to work only partially for the rightmost part but at least it did not come out the full way.

The new raft procedure is SO much better than the old one.. I may start printing with rafts all the time if they come off as easily as this one did.
This one features A Boy Smoking a Cigarette apart of some advertisement, I couldn't actually find the name for this piece, but I thought the clothing choice - a cowboy theme, was very interesting,

The deconstruction and replication of my chosen shoe was a difficult process. Considering the hours and creativity put into constructing my shoe entirely out of masking tape, I am proud of it. The original shoe and the finished prokect look almost identical - minus a few probelms encountered while constructing the duplicate.
The masking tape duplication is almost the exact size and proportions of the original. Also, the masking tape replica even fits my foot! However, it took so much time just to construct the form and outer contours of the shoe that I did not get a chance to create the rectangular rivets on the bottom sole. Moreover, I had issues creating a flat bottom surface with little bumps and lines within the tape. It was difficult to creat a smooth look with the tape to look like the realistic leather on the original shoe. The masking tape is so sticky that it is hard to build a good base with barely any flaws. In addition, I was extremely suprised at how tape could form such a hard medium when layered together. The overall project was challenging and I learned that achieving flexibility with masking tape can be done.
As a result, I feel project one was a success and feel that I put in as much work possible. Even though the bottom sole of the masking tape shoe is not entirely completed, I think the shoe itself shows the hard work it took to construct a replica of an original shoe.
