I was going to show the video I made but the machine said It was to big. No go. So we will just do the photos. When I completed the excavator model I posted it on a Cat site as I was looking for the location of the shovel front machine for measurements. I had been looking and asking of and on for 15 years(ever since I made my 1/16th scale model1999-2002. I got info that a contractor In Pittsburgh, Pa had one. The next day I called Their office to check the info. They had one, it was in Wheeling, West Virginia, I asked for permission to take photos and measurements and they said yes. The next day I drove 160 miles to Wheeling and got my measurements and photos and drove back home. The next couple of months where spent making booms, cylinders and the bucket.

I had to think outside of the box to make my cylinders as I had no way to drill the long bores I needed. The rams in the cylinders were 3/4in. I got a 3/4in core bit for my router and made them in halves and glued them up. To get the bore large enough as my core bit was 3/4 and my rod was 3/4 I planned ahead. I did the 3/4runs then I put a layer of tape on the straight edge I was using thus pushing my 3/4 run side ways. After they all reached this level I reset the bit that much deeper. Now you glue up and turn the outside shape


These pieces were turned for the outer end of the cylinders and glued on later.


The travel of the rams are right at the maximum so they need to be really close or they will come apart. The cylinders are hard to measure by yourself so you do the best you can. I the first on dose not work, throw it away and redo till it is right. Most times I am ok. I do not need to remake to many pieces. I lost some of my photos(My pc ate them). Will try for more another day. Enjoy
