http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K010_zps4e47f872.jpg This is a Cat D8K dozer that i am currently building.I got as a kit, made by Arpra from Brazil. It usually come with a angle dozer but since i already had in my collection a D8K with angle blade, i decided to build something a little bit different. More pictures to come, as well as a description of the work involved. Max.
Hi!! I am back.....( i wish i'd be able to show py pictures directly but it seems like i am doing something wrong.....it might have something to do with the size of my images.....) So that model is in 1/50. For those who are'nt familiar with the scales, the dozer is ptrtty much the same size than a coffee cup. The blade come from a Norscot D8R. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K002_zpsc0df303c.jpg The gap between the blade lift cylinders on the D8R being narrower than on the D8K, i had to remove both inside ears, so on the new blade, the outside ears became the inside ones.To build the outside ears, i used a 3/16 brass angle. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K003_zps3218866d.jpg
Next thing i did was to cut the components that are gonna give the D8R blade a U-shape. Both inside curled pieces are made of 1/32 brass sheet.I press the pieces against a circular object in order to give them the curve shape-it was a piece of steel pipe, approx 5/8 in diameter. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K001_zps369180cb.jpg The next pieces are shims that i added in order to make the new blade 1/16 wider on each side.On the real machine, 1/16 would mean a little over 3 inches. The last pieces(both outside brass pieces) are upward cutting edges.They are sitting gainst the 1/16 shims and on the curled pieces.
http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K004_zps838837fc.jpg The new parts are hold in place using pins that i cutted in a .032" brass rod(.032 roughly equals 1/32") It keeps the parts from shifting while being soldered or glued.
some of the new aprts are soldered.When i can not solder them-either because sitting on white metal or because to close from another weld, i glue them using JB weld. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K005_zps6720a778.jpg http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K006_zpsffa7e8c6.jpg More pics and details to come soon..... Regards. Max.
On the D8R, the blade arms are empty-or if you guys prefer, in some kind of C-shape.On the D8K, they are square. In order to fill the gap, i used a 1/8 X 1/16 brass C-channel. Also, the blade hydraulic tilt cylinder are female while on his ancester, they are male.That's why i added a ear on the C-channel.I cut one ear on the D8R plastic sleeve in order to make it male. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K009_zpse3bd756a.jpg The stabiliser bar on the D8R became the blade pitch control linkage on the D8K http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K013_zps741c005d.jpg I shortened to an appropriate lenght and drilled the hole for the pin. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K012_zps52f97789.jpg
The D8k will have an enclosed cab as well, that is built out of brass. http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K015_zps8a48b13d.jpg The reason for the mesh behind the window is that this dozer will be equipped with a winch(to be installed later) http://i1288.photobucket.com/albums/b484/olygremlin/ArpraD8K014_zps5142a058.jpg Theire is a bit of work to do here and there before it is finished. More pictures to come as the work progress. Regards. Max.
