enginear joe Posted March 19, 2018 Share Posted March 19, 2018 take a look at this larger table on a laser this guy built. I'm always looking at stuff and feel like a dinosaur! I think this is one of those kits out there? https://ogrforum.ogaugerr.com/topic/2d-laser-engraver-finished?reply=78579203781536215#78579203781536215 Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 19, 2018 Author Share Posted March 19, 2018 The nice part of having a cnc router/lazer, is that one could have four machines in one. I can run a router motor, a drag knife cutter, or I could install a lazer head on it, many possibilities. Also, when I install the pen, one has a plotter for drawing. Bob.

rbrown7713 Posted March 19, 2018 Author Share Posted March 19, 2018 I don't know if you saw my build on Homemadetools. net, but here is the whole build of my cnc router. http://www.homemadetools.net/forum/cnc-router-build-adept-robotic-cartesian-slides-21166 The only difference of my build and most homemade routers is that I used Adept slides for my axis. This way, I didn't have to build each slide. Everything is already built. No assembling of the slides, with the ballscrews, and then the servos, all pre-made. Also, instead of noisy stepper motors, I used servos, very quiet. I probably spent 3000.00 on this project, maybe 3500.00, but it was worth it. It is a 48 by 48 inch table. Bob.

enginear joe Posted March 19, 2018 Share Posted March 19, 2018 Looks great! Didn't get to see it all. Some screen popped up that demanded a download and froze the rest. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 19, 2018 Author Share Posted March 19, 2018 I don't know what happened there, but just stay on the forum and don't click any of the advertisements and you will be ok. Bob. Quote Link to comment Share on other sites More sharing options...
Jerry B44 Posted March 19, 2018 Share Posted March 19, 2018 Just amazing! I tried to find one of his longer super liners, but gave up. Wanted one for my Santa Fe set. I'm sure yours will look better than Ralph's. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 19, 2018 Author Share Posted March 19, 2018 I think all of the longer Superliners are sewed up. I think only ten were made and quickly bought up. Yes, I am trying to fine tune them and add a little detail, and we shall see. Still lots of work to do, but I am having fun. Ralph gave me a good platform to work from and that makes it easier. Bob.

rbrown7713 Posted March 19, 2018 Author Share Posted March 19, 2018 While making the pattern for the Superliner mold, I realized that the weight of the urethane after pouring could deform the pattern and make the vertical concave. So, here is what I did to combat that possibility. I put height braces along the center of the length of the side to stop any sagging. Here is what I came up with. Bob.

rbrown7713 Posted March 22, 2018 Author Share Posted March 22, 2018 I painted one of the patterns to see how the Krylon works, so, so. I will be trying some more silvers to make it better. Bob. Quote Link to comment Share on other sites More sharing options...
enginear joe Posted March 23, 2018 Share Posted March 23, 2018 It looks good from here. Do you want more shine? or a more metallic look? I was wondering if a clear gloss coat over top would be correct? Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 23, 2018 Author Share Posted March 23, 2018 I want it to look like stainless. Some of the chrome paints, when done properly, look just like metallic chrome, but that is too shiny for stainless, so I am still testing. Adding a clear seems to dull the shine slightly, so maybe that is the ticket, so we shall see. Bob. Quote Link to comment Share on other sites More sharing options...

Jerry B44 Posted March 23, 2018 Share Posted March 23, 2018 I gave up on Krylon, too many problems. I use Rustoleum 2X , it works with their primer and clear coat. Never can tell with Krylon. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 23, 2018 Author Share Posted March 23, 2018 I will try them. Have you tried Rustoleum silver 2x? Bob. Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted March 28, 2018 Author Share Posted March 28, 2018 Finally, ready to make the molds for the lounge car. I found out that it takes a long time for the silver to dry. Bob. Quote Link to comment Share on other sites More sharing options...

enginear joe Posted April 12, 2018 Share Posted April 12, 2018 Don't know how in the world you changed that so fast? Looks better! I spy a can of mold release. (bity supply?) Quote Link to comment Share on other sites More sharing options...
rbrown7713 Posted April 12, 2018 Author Share Posted April 12, 2018 It was easy. Just had to grind off some of the mount area of the side rail and the top of the bearing box. I tried to buy some wheelsets from Gary Raymond, but the style that I had bought before, he is out of and doesn't know when he will have them made again, so I am looking into some NWSL wheels. Yes that mold release is from BITY mold. I only have one more pour of urethane for the roof of the lounge car and then I am finished making the large molds, all done. I am starting to work outside again. Bob. Quote Link to comment Share on other sites More sharing options...
