There are so many random tutorials out there for it, but in the end, they are not cohesive - from beginning to the point where it is useful for working with on our CNC machines. It would just be great to have someone to make the process more clear.

Our current brewing system is.... quirky. Liam and I are able to get good beer out of it but it's hard to clean, and hard to learn. A new all in one brewing system is relatively inexpensive and should be able to make batches quicker and with less to learn.

Wiring and Programming HuanYang VFD for 2x72 Belt Grinder

Submitted by Lior Trestman on

I'm posting this blog because it took me a while to find the correct codes to program this VFD with, so hopefully by putting all of the information in one spot someone else will have an easier go of it.

 

This is the VFD that came with a 2x72 Belt Grinder bought on Ebay (from Remmer-4513). In the end, the codes that worked for me were:

-PD002: 1

-PD003: 60

-PD004: 60

-PD005: 60

-PD070: 1

-PD072: 60

 

I wanted the belt grinder to be foot pedal controlled and have an on/off switch, so I wired in series a foot-pedal and on/off switch between the FOR and DCM pins.

In order for two tubes of metal to be welded together successfully, one needs to have a precise hole cut in it. This machine does that. Bicycles, geodesic dome structures, roll-cages, and aircraft frames all require tubes to securely fastened at irregular angles.

Etching Brass with the Lasers

Submitted by Lior Trestman on

I made this plaque to commemorate Steve Buda and the tools bought with donations made in his memory. 

  1. I bought brass sheet from Goody's Hardware in East Haven
    1. It was a kick plate for a door
    2. Not brass plated, but solid brass
  2. I bought CRC Moly Dry Lube from Napa Auto for ~$20
  3. I cleaned the brass with rubbing alcohol, rubbed it with steel wool for a bit, and then cleaned it again.
  4. In the fume hood I sprayed the brass with the lube. I gave it 3 coats, with about an hour in between each coat.
  5. I used the Universal Laser 60W CO2 with air assist, set to 100% Power, 0.9% Speed and
Famag IM-8 Spiral Dough Mixer. A spiral mixer's purpose is to gently mix dough while developing gluten structure without overworking the ingredients. This results in a higher-quality dough.

The Pottery badge is required to use the Pottery Studio. Only Liz's Light Cone 6 Stoneware clay can be used in the area to prevent contamination and kiln mishaps.

 

There are blue silicone mats on the shelf to use on the tables for hand work.
