Grills for scratchbuilt E8 locomotives

Recommended Posts

Yes, and another interesting ad on the same page is Robert's Lines. Pouring another one today and I built a stand for the funnel so disaster doesn't strike again. Bob.

This is yet another mystery with this E-8.  I am wondering what the question mark means marked on the mold box?  Did the worker that looked at the actual mold not know what an E8 loco. was? Open for suggestions. Bob.

I am ready to pour the second shell and this time I built stand for the funnel so that it doesn't tip over again, not fun. Bob.

Well, I poured the second shell and it went without incident.  Poured 2 lbs. of plastic and the plastic showed in the vents and that was it, should be a good shell.  This time I will try to wait 24 hrs. It's hard to do. This pour is for the B unit end to attach to the A unit to make a B.  I measured the the end and compared it to my B unit and it matches up perfectly with the vertical battens.  Shouldn't see any seam. Bob.

You're on a roll now!!

I hope it comes out of the mold easer with it being cured longer ..

Yes, I think it will and also I will be using spreaders to make it easier to spread the mold and therefore allowing it to slide easier. Bob.

The shell came a little bit easier, but really doesn't want to come out without a good wrestle.  I hate to cut up these two shells, but If I want a B unit, that's what will happen, Bob.

Thanks Joe, the only bubbles that occur is on the bottom rail and I cure that by using CA to fill and shouldn't be able to tell after sanding.  I have cut up two A units for the B unit and plan to make a mold for the B unit end cut. Bob.

Here is my design for the B unit other end mold design first section of the mold.  This is tough one, but I say that about every mold I make.  It would be a lot easier if it wasn't for the 1/4 inch roof overhang.  I don't, at this time if this is going to work, but we shall see. Bob.

He hid a possible  uneven seam on the roof.  Here is the beginning of the second part of the mold and I think it will work well and the part will easily be able to be removed. I just saw, by looking at the picture why, in the original mold, he designed the mold to extend higher than the bottom rail was to avoid the roughness that I have on mine and I will remember that for the next mold.  Now, the part that comes out of this mold, I will have to sand out and repair the bottom rail. Bob.

If you look at the end piece, there are angles that would complicate removal from the mold as it is hard enough to remove it, as it is, even with relatively flat surfaces.  Here is the mold almost ready to pour the second part as soon as I get some more silicone. Bob.

Poured the second half of the mold for the end section of the B unit.  Most of the molds are complete for a complete E8  A AND B unit.  Still have to make molds for the brakes and windows. Today I will be making a drawing of the frame and all of the holes, lots of different size holes. Bob.

Are you going to pour the frame or make it out of aluminum ... Hmmm could you por some metal to make it ...

The frame is aluminum, just like the original, same alloy and thickness.  I am making a drawing so that I know where all of the holes are to copy. Bob.
