Clevis rod end

Sets of wax models before being shipped to the foundry.

The first ones gone for $700 a piece. Taking into account time I spent on each my hourly rate was very low . I know someone then sold one of my vises for 2k. I do not see how it can be cheaper than the first batch.

I need to finish another one too.

Here is a "shrinked" version of Boley vise and it's original size.

There are no secrets. The technology is available and widely used. The equipment I used came from jewelry because of small size of my items. You can buy all materials from jeweler supply websites such as riogrande or similar. Organizing casting session with students will require some...

It was vacuum casting. You guessed right.

I tested jaws. It fits in slots. Need to drill and tap holes in the body, counter bore jaws, and turn heads of #0-80 screws.

In order to cut slots for jaws I needed a tiny key cutter. The one I had was too thick so I ground material from it with Dremel tool on the lathe. The cutter I made seems to work fine. At least on bronze.

Today, I made a pedal from thick gauge copper wire. Round part is bent while two straight sections I rolled flat using rolling mill. I also fitted two dies. It comes snug and it can be wedged in the future. I will pin the clutch in the future and start adgusting everything to make a smooth...

I checked my files and found that first pictures of Little Giant I downloaded back in January. Probably in February I started working on CAD files. It was not continuous work since I had another projects running in parallel. Roughly end of April when files were ready and wax models creation...

One more element is ready for casting

Here is a picture

It is stiff but it is already reciprocating

I made a spring on my lathe.

Ram is installed. Links are next

My milling machine is operational again. I mill the V-slot for the ram. First pass with 1/32" end mill to clear the corner. Then 90-degree mill to make sliding surface.

I was fitting two arms that will drive a ram. No spring yet.

Today, I made some progress with yhe flywheel. It is assembled along with crank, clutch bearing caps and rotaiting ring. Fork will follow.

Some progress with the front shield. Now it is attached on #0-80 screws. Bearing pads installed as well.as the main shaft. The ram installation requires milling the slot in the body. I will make it when my milling machine will back to operation.
