Thread: anyone do large scale models as a hobby?

Tweet

In addition to tinkering with hot rods I also tinker with large scale models and was wondering if anyone else did? I don't actually build them, I'm kind of a parts supplier. I do resin casting and although I do mostly 1/8th scale I do make some smaller stuff as well.

Thats cool, post some pics if you can I personally would love to see'em. The only scale I have done is 1/1 so far.

I make large scale models. They are approx 1/3 scale.

Made of timber. Mostly MDF but with other timbers.

This is a Woody I am presently doing. It will have a matching woody trailer behind it.

I tried to do a 1/16 model of Revell top fuel front engine dragster-----------ended up making a 1/1 rear engine replacement--that worked out pretty nice
I've had better luck with the 1/25 die cast models from 1320inc.

Those are Kool. I like the hemi and really diggin those E&J type 20's. I cast those in 1/8th and 1/12th scale. https://public.fotki.com/BIG-JIM/ite...hop-truck.html

That is totally awesome! You do amazing work. I really dig the Hemi and would love to have one to put on my shelf!

I used to build a lot of models when I was young, before I started working. (Before I got my driving permit) I haven't finished a model since. The last model I started was a 1968 Corvette that I pro streeted and primered. I did this when I was on a training trip for work and was stuck in a hotel and had nothing else to do. Maybe I should finish it. The real car is painted now.

My favorite ones I had were my 1966 or 67 cobras. I had a 1/8 scale cobra and 63 Corvette. Now the 1/8 kits are so expensive, I would just rather buy a real hot rod part than the model. When my kids are a few years older, I'll probably get back into it. I think they'll enjoy it.

just a few of the things I make.

Those are some mighty fine parts.

Are they resin cast? Please explain the process, in detail.

I am still into the model stuff a bit. I ran an aftermarket company for a long time in the 90's and early 2's. Machined Aluminum Specialties if you were around back then.
Nice looking parts.
I also do 3D Cad models and have stuff 3D printed if you are interested in anything like that. The printed parts make excellent masters for resin casting.
These are some 1/16th scale cheater slicks I modeled up and had printed.




They are 5 separate pieces so they are easy to cast. I can scale them to whatever size you want.
I can do just about anything you could think of.

Yes they are resin cast. There are a lot of different ways to cast. I use one piece open faced molds where ever possible. This is just a matter of using double sided tape to affix your part to a flat surface, put a mold box around it and pour your RTV over it. Twelve to sixteen hours later once the rubber sets you can remove the part. Then just mix 2 part resin mixed well into the mold and it hardens up in minutes and you have a part. Then you have 2 parts molds. In this case you do the same thing then flip it over once cured and pour the second side. With this one you can leave it like it is and just pour the resin in and press the two halves together. This is called a squish mold because it squishes the resin out. You can also cut a fill tube and a vent into a two part mold and pour the resin in that way. As you pour the resin in the air comes out the vent till the cavity is filled. Then you have 3 and 4 part molds. Those are very complex. Then you have slush casting and rotational casting. I'm doing a slush cast now of a 1/8th scale 33 ford 3 window coupe body. This is my first one. It is a lot of fun. The hardest part sometimes is planning the way to make the mold. You have to figure out how the resin is going to flow and where air may get trapped. It can be challenging at times. If you are on facebook look up my group RATRODZRUS SCALE MODEL CARS. there is a lot of info there. I go through things step by step.

I wasn't even thinking about 3D printing. It will truly revolutionize a lot of hobbies such as modeling.

In my drafting class, I used SOLIDWORKS to draw a balancing toy which was then 3D printed.

The balance wasn't quite right, due to the printing process. As a means of reducing material use, the interior of a part is made less dense.

But, I've still got it. It doesn't have any real value, just like the test piece I cut on a lathe for a machine tool technology class.

Here's that body I was telling you about. This is the first one.

That looks very nice. I finally found a place that has 392 Hemi's. I picked up a 40 tudor model so now I can make a small version of my 40. I wonder which will get done first?
