Good start on next 1/16 scale project.

It is a Case 50's vintage model S-139 disc harrow. I got the 2 front gangs built, and some frame members cut.Ended up having to order more brass angle to finish frame.

Here are some pics of the build process Making conical discs from flat washers. I just use a piece of 1" black iron pipe and a 5/8" carriage bolt and center washers on end of pipe and whack with a hammer. to form the discs.

I use a piece of cardboard to lay out the design and then modify slightly to maximize the brass stock.

Tomorrow I will hopefully, build the 2 rear gangs and start soldering the frame pieces that I have cut, together.

Dad bought a 8 foot Case disk in 48. You pulled a rope to angle it. What number would it have been. Pull it over a lot of acres, but never seen a number on it.
 
Nice work, Loren! I'm going to file that disc-forming idea away.

I've got another project on the bench, but I'm going to wait until it's a little further along before posting any pictures. Main material is aluminum flashing.

For the poster below that asked about epoxy - In the process of this build, I learned a couple of things about epoxy since aluminum isn't solderable. You must rough up the surface to give it a little "tooth" or the epoxy won't hold. I initially used the clear "5 minute" stuff and as soon as I flexed the joint even a little bit it popped loose.

Thinking good ol' JB Weld would work, I ran into the same problem. It did hold a [i:654c4848f0]little[/i:654c4848f0] better, but not enough to be trustworthy. I had to use 60 grit paper and really crosshatch the surfaces to get it to hold and I still wouldn't bet the ranch on the strength.

The same would hold true for brass. The surface is just too smooth.

Solder is quick, easy with a little practice and the right tools, and very very strong.
 
You do very nice work.
This is my first attempt seven years ago to build toy implements.
I used galvanized sheet metal and steel bar stock.
I tried the washer whacking trick but couldn't keep the disks all alike.
I ended up stacking a gang of washers in a hydraulic press and mashing them into submission.

Nice job. Really "gutsy" starting from scratch.....but you seem to be quite capable. I build kits from cars to ships to planes to train layouts in scales from 1/16 to 1/144. Getting to where I'm running out of room for all of it. Sure beats outside working on tractor restorations which is what I used to do with my winters.
 
The extent of my machine shop tools is a Porter Cable combination disc/belt sander and a Dremmal Tool. The rest is hand tools. (Hammer, pipe, vice , and hacksaw.) I clamp two pieces of 1" angle iron in the vise to make bends. I could never justify the prices of mini machine shop tools.

There is a company called K&S metal products. They make all sorts of metal shapes, from round rod, round, square, and rectangler tubing, all sized to make telescoping pieces. They also make channels, angles and sheet stock. in sizes that are in scale for my projects. The brass is very easy to form and solder. and I can get it from several sources.

Somehow a Mini Machine sales booklet wound up in my mail box. Couple of glances through that thing and in the trash it went. Wayyyyy too expensive.
