Back to the bench
Maybe a little fuel for thought with the very industrial appearance and finish on these old machines. Sorry for the spam if this is not of interest.

I'll double the thanks for the link.

And, for getting me to imagine chain drives for the wheels, which would be cool, too.

If possibly one wanting raiding an old Mechano set or two . . .

Thanks for stepping up, Mate. I appreciate you, Timmy, and Bill doing so. I am submitting your names to Nemo for the highly coveted Captain Nemo Engineering Recognition Award. He does not care about creature comforts on his war waggon, but he appreciates high level engineering on his projects.

Now this recomendation to the Cap'n, does it come with a couple of good lookin sheilas and an obscene amount of money???????????????????

Mate I also like Cap'n Mac's Big Bertha idea. Glad your the one having to make the decision. As for me I'm going to down a frothy or two.

Actually Dodgy, the recogniton award was to you, Bill, and Timmy. I'll throw in the latecomers too. Now... understand... the award has no intrinsic value.  It comes with no money, not sheilas, no nothing. Heck.. you don't even get an actual award! Lol. Sorry about that. But hey... it's a major award!

Times are tough you know. Nemo is floating IOUs until we get this gold mining operation in play.

Cheers Mate!

I tried working the green beasties but it was like a pig with lipstick. Maybe if I kept at it, I might get something, but I was just not feeling it.

Then I thought that maybe I could morph parts of the steampunk gears with the beasties. My grinding bits struggled to cut through the metal. I would have been there for ages. "It wouldn't be prudent." This then left me with trying the steampunk gears on their own merit and I have to say that it magically came together. 

I cannibalized the spoked wheel shown in my previous posts. I cut the hub out and fit it into the piece below. It worked fantastic. The rivets are not yet glued, nor is the hub. 

I had a heck of the time gluing the three pieces together. For one-- the CA was not holding very well. I eventually filed off the brass patina and that helped. Secondly, the three pieces were a little tough to align. In the end they are not perfect because they are just slightly different enough that they don't align in the configuration I have them in. But for my purposes, they are acceptable to me. 

 

So where does this leave me. It leaves me with a piece that I visually like, but that I hate for its weight.

I will next explore the idea of making a resin cast. It probably won't work for me because I will half-axx it. Why? Because I won't spend the bling for all the special mold materials and such. I will try on the cheap using blue stuff and go from there. 

Worst case scenario will be using the metal pieces as is and hope for the best.

End of update.

I think thats going to look great. Have never used Blue Stuff, or even tried molding anything, so I'm no use to you here. Good luck mate.

Since the wheels will be on the ground, you will only have the weight of the coach on the axle spindles.  An alternative might be to finish hollowing out the axles and epoxy in a brass rod.  Would also go a long way to filling them and get an axle without the slots the molding process left.

Thanks Dodgy.

I am no expert with molding either but I have dabbled some. The blue-stuff works ok  but it tends to trap air bubbles as you press the stuff in place. That has been the biggest drawback, in my experience. It takes some monkeying around.

Other than that it is easy to work with and it does not take much setup to try this, so, I will. Maybe I will get lucky.  One other thing I forgot about the video. The guy uses two part epoxy for the cast. I have some of it, a different brand, and from my experience casting with it, it  captures good detail, it is light weight, it's strong, it has low shrinkage, and it sands/drills nicely. I will try that, and not resin. 

All.that said, maybe 50/50 this will work for me. Either way, I will report back.

Exactly right. So if I have to go with all metal, I won't install the wheels until the very end. My biggest concern would be having them installed early on, all the handling putting stress on the undercarriage. That said though, I would prefer to install them earlier than later because I will want to gauge clearances as I work on things. There is my dilemma.

Something to consider. We'll see how this shakes out. It's all part of the journey!

Thanks GH!

Using the epoxy was a BIG el FLOPPO. It did not produce the detail I had expected. The epoxy that I used is a different flavor than what I have worked with before, so that might have something to do with it. It doesn't matter though because I quickly found out that two part epoxy is not a good fit with two piece molds. You basically have to squish the mold together and that can lead to distortions with the cast. The best solution would be a liquid resin.

This presented a dilemma. I can't use quick setting resin because the resin generates heat, and heat softens blue stuff. It would basically destroy the mold detail. The only other option to consider is a slow setting resin, and I just so happen to have some called Puduo. As a hail marry pass, I tried it. And what do you know-- it worked very well.

I am amazed at the amount of detail that both the Blue Stuff and the Puduo had produced.

At this point I could stop here and move onto making all 4. The downside is that the mold process won't allow me a more precise finished piece. This cast needs to be trimmed not only along its circumference, but also within it's spokes. It could be a lot of work. This got me to thinking. I have gone this far-- why not make a better mold using silicone. Yeah, I'll have to drop about $35 to buy it--but I should end up with a much better end product. If done correctly, there ought to be little flash, and the internal structures should come open like the master is. Or at the least, maybe a thin film of flash that can be easily trimmed. The above will not be easily trimmed. I'd have to grind them open.

I could also purchase a fast setting resin but that is another $35 to $40 bucks. This is why I like to avoid all this fuss with molds and such. In the end I could spend $70 to $80 just to make 4 wheels. That is ridiculous. And to make things worse-- these products have a shelf life, and a short one at that. If I could use them for a future project, that would be a different story. But that is not the case. Once opened the resin goes bad after maybe 3 months, not sure about the silicone, but I hear it is not that long either.

So-- for the sake of a better product and to take a shot at learning a new process--I will buy the silicone. For the resin, I will stick with the Puduo. It seems to work well. The main downside with their product is that I have to wait a good 2 to 3 days before demolding it. That's ok, I can wait.

A few more points:

1. I plan to attach the hub and rivets so that they become part of the mold/cast. This will reduce some work and gain some consistency. I need to make sure the master is done right then.

2. Remember what I said about the bubbles and Blue Stuff? I think I figured out the problem. As in the video it is recommended that the product be boiled until soft. Here is the problem. Doing that introduces water into the mixture and that creates pockets in the mold. I decided to use a heat gun to soften the material and guess what? I had seen no issues with divots. If anyone tries this -- just be careful. The stuff gets gooey and if too hot-- you can burn yourself. Blue stuff is cool stuff, and it has its place for simpler molds.

And that is enough bloviating on my part.

Hey Cliff, well, you came to the right place. I am interested in how it goes for me too! Surprise I will document this step by step. It will be the good, the bad, and the ugly. 

 

I have high hopes, and that is usually when things go south on me. Indifferent

I ordered the mold material today. I will try Smooth On, Mold Star 30. 

https://www.smooth-on.com/product-line/mold-star/

Looking forward to trying this. I have always wanted to make a silicon mold but I never saw the need for all the fuss.

Yeah. He is 91 years old and still dedicated to his passion. Anyone that drives their gift to the end like that gets my total respect. What a great example of someone living his life to the full.

I remember seeing his first spaghetti western at a drive-in theatre. Love the music too.
