Stain Dipper Machine Top Pulley Assembly

One of the key components in the Stain Dipper Machine is the top pulley assembly.  It is crucial that it normalizes the unspooling location of the cable so it does not put lateral forces on the slider rod below.  To this end, we designed and created 3 components out of UHMW (Ultra High Molecular Weight Polyethylene).  It’s a nice plastic to work with, and super tough.  It cuts like butter but has a lot of strength too.  This is a 10mm hardened shaft with two bearings pressed into the UHMW.

Here is a picture of the 3D model.  As you can see I haven’t trimmed the shaft yet.

One-Off Cast Iron

I had an incredible talk with Craft Pattern today, about making a custom cast iron machine frame.

http://www.craftpattern.com/

They really took the time to talk me through the process and helped me understand the different techniques used.

Isn’t it great when you get to talk to someone who knows what they are talking about?

Have you considered cast iron as a possibility on any of your projects?  I hadn’t until recently, but now a whole new world of possibility has opened up.

In addition to casting, they offer full CNC machining services on the castings, so it sounds like a one-stop-shop.

 

 

 

A new part for an old Bentley restoration

At Sinking Valley Woodworks, we take on odd jobs from time to time.  One of these odd jobs was some car parts for an old Bentley restoration.  Wood was a much more common material in cars in that era.

This particular piece is what goes at the top of the windshield and connects to the roof.  It has curves on all faces, and compound curves on most.  The new part was made out of Ash, carved on a CNC router, and finished by hand.

Below is some before and after pictures.20151002_141251 bentley part
