Jerry B44 Posted November 1, 2023 Share Posted November 1, 2023 Love those angled fronts. I have one that Roberts Lines did in a cast aluminum shell, heavy! Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted November 1, 2023 Author Share Posted November 1, 2023 Boy Jerry, that looks fantastic. I hope mine looks that good. I am also going to make an E6 stemming from this project. Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted November 7, 2023 Author Share Posted November 7, 2023 I thought I would share this with you. For the E6, I am making the number boards and cut out these on my laser. This is just the start, they have to be smoothed and I have to make a mold. I am surprised how accurate the laser is. These are just slightly over 1 inch long.

rbrown7713 Posted November 7, 2023 Author Share Posted November 7, 2023 Yes, I really like the shape of these boards, so I had to model them. Here is the pattern for the number boards, next make the molds. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted November 8, 2023 Share Posted November 8, 2023 These look great so far, I think. I don't know where they go! What road will this be? Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted November 8, 2023 Author Share Posted November 8, 2023 OK, I should have more clear. The 3d printed part of the front of the loco. is going to be used to make 2 different loco's. The front, or pilot, on the E1 and the E6 are very close in appearance. So, the number board that I am modelling is for the E6, and I haven't yet decided on a road. Bob.

rbrown7713 Posted November 12, 2023 Author Share Posted November 12, 2023 Here is the mold for the E6 number boards. Next, I will have to order some urethane plastic. It is taking time to sculpt the front of the loco, as the print didn't project the real look of the prototype, after comparing photos, so it will take some time to shape. After listening to many 3d printer experts, they say that PLA plastic is not compatible with exposure to the sun, so if anyone makes a model from a 3d printer, one should use ABS, or PETG, or some other filament that is more suitable to UV resistance. I am using PLA because I am making molds from these PLA parts and will make them from Urethane which has a better resistance to UV effects. Bob.

rbrown7713 Posted November 15, 2023 Author Share Posted November 15, 2023 This xtool laser is very handy, I am finding out in making parts accurately and easily. E1 rear windows. These will be patterns for a mold. Bob. Quote Link to comment Share on other sites More sharing options...

rbrown7713 Posted November 18, 2023 Author Share Posted November 18, 2023 In case anyone is interested in this engraving procedure, the plastic is Trotec Trolase black/white 2 ply 1/16th" sheets from Amazon. The laser used is an Xtool D1 pro, settings were speed, 400mm/min., and power is 10%. I found that due to my inexperience in cutting, it messes up the edges because of the higher power needed, it is better for me to cut it with a Dremmel grinder, that is the reason for the outside lines. Also, an added bonus is that an led light behind the numbers will shine through the white and light them up. Bob. Quote Link to comment Share on other sites More sharing options...
