South Bend Lathe

Lathe history:

This is a 1927 South Bend lathe. It was originally purchased by a German immigrant to the US named Karl Nilson, who ran a blacksmith shop in the Schenectady, NY area. On his death, his widow sold it to Frank Mossey, it then went to his eldest son, Gerald, and then to his oldest son Kevin, who is sick of lugging it around the country. Kevin donated it to Denhac and hopes it will find many more years of love and use.

Info:

11” swing over bed
4’9” between centers
1/3hp reversible electric motor
Self threading attachment
3 jaw and 4 jaw chucks
Spindle Speeds*:

Without Back Gears
High (left) Medium (middle) Slow (right)
885 558 362
Back Gears Engaged
High (left) Medium (middle) Slow (right)
149 94 61

* Speeds are approximate, based on counting rpm with the back gears engaged, then counting gear teeth and multiplying by the back gear ratio. Back gear speeds may be off +/- 2 rpm, and non-back gear speeds may be off +/- 12 rpm.

Safety information:

This lathe was built back when safety advice was “Don’t kill yourself, and if you do we’ll just find someone else to do the job”. If you use this tool you must be aware of your surroundings and mental state at all times. You should not wear loose clothing, jewelry, or hair while using this machine. If you have long hair it is recommended you tie it up while using this machine.

Do not change the direction of the motor while it is running! Ensure the machine is fully stopped before reversing the motor direction!!!

There is an on/off switch located at the front of the machine on the leg of the base. There is an emergency stop button similar to the one on the laser cutter on the power strip that you can leave by your foot to stop it. This will not stop like the sawstop, there will still be angular momentum and it will continue spinning until friction stops it, but it will stop fairly quickly.

Before turning it on ensure that:

  • The motor is set to the direction you want (99% of the time you’ll want it in the “forward” mode).
  • The work is securely fastened in the chuck, the chuck is securely fastened on the spindle, and the chuck key is NOT in the chuck. A good rule of thumb is if the chuck key is in the chuck your hand is on the key. If your hand is not touching the key, the key should not be in the chuck. Put it another way – if you let go of the chuck key, it’s only to put it away where it belongs.
  • The tooling is appropriate for the material to be cut, and is not touching the work piece.
  • You have verified the threading gears are disengaged on both the head stock and the carriage if you are not cutting threads (easiest way to do this is spin the chuck by hand)
  • If you are cutting threads you have verified that the thread gears are configured properly
  • The drive pulleys are disengaged (throw arm lever pulled forward)

When cutting, don’t be greedy. Depending on the material you can get away with more material – aluminum and brass you want to limit yourself to .020” (20 thou). Delrin, teflon, and other plastics you can get away with 0.030”, but steel you may not want to do more than .010” per pass. If the tool catches because you got greedy, stop the lathe and back the tool away. Reassess the situation and proceed cautiously from there.

Changing the chuck/chuck jaws:

The 3 jaw chuck has outside jaws and inside jaws. The chuck teeth are numbered, and will come out in the order of 3, 2, 1, and go in in the order of 1, 2, 3. Keep the teeth together and don’t get them confused with the chuck jaws of the other lathe.

Place a flat wooden board on top of the bed before removing the chuck. Lock the gears in place and use a breaker bar in the chuck key hole following the rule of lefty loosey righty tighty. The wood is to protect the bed in case you lose your grip on it.

Fujitsu fi-5750C Scanner

Access

The scanner is currently in the fishbowl room.

Feel free to connect its USB to your Windows/Linux laptop or use the web UI from the headless server.

Connect to the denhac wifi/LAN to be able to reach the scanner server website.

http://scanserver:8080

web based file browser: http://scanserver:8081

This will improve later, but remember not to leave your scanned documents on the server!

Specifications

Flatbed scanner for up to A3 or 11 x 17″ sized documents, with a 34″ extension possible (somehow?)

Duplex ADF for large stacks of letter sized paper

USB 2.0 interface with Windows or Linux drivers (no Mac driver)

Up to 600 dpi 24-bit color outputs

Currently connected to a Chrome box server with UEFI firmware running GalliumOS for x86

Standard denhac login credentials for the chrome box server.

Files are stored in /var/www/… something

Scans go to /tmp/scanned directory, and can be managed from within the web app or the filebrowser on port 8081.

Filebrowser is in a docker container, scanservjs is on bare metal in a nodejs process.

There is a desktop environment on the chromebox that can be used, but there are no peripherals attached.

Workflow Improvements

https://github.com/sbs20/scanservjs/blob/master/docs/integration.md

/tmp/scanned could be the mount point for any inserted USB flash drive, it would need a tool for a headless safe eject option

The preview image files might be kept around and not deleted! Storage will fill up quickly as it only has 16GB.

Right now filebrowser’s docker run script is in /home/denhac/filebrowser/

None of this is imaged or in an ansible script or has PXE boot enabled, so be careful right now not to break this setup.

Evolution S380CPS Metal Chop Saw

Description

The Evolution S380CPS is unlike conventional abrasive chop saws. It utilizes a circular saw style blade with tungsten carbide tips that far outperform abrasive cut off machines in cut quality, blade life, and safety. Evolution saws are much cleaner, faster, and safer than torches, portabands and other methods for cutting plate, sheet metal, tube, pipe and angle iron. A 15 amp motor provides plenty of power for most all cutting applications.

New features include a carry handle for portability, a cast aluminum base, and an improved vise design with miter detents and a locking pin for quick and repeatable miter cuts! This saw can handle up to a 15 inch diameter blade for even more capacity.

Metal Chop Saw Use and Safety

  • When clamping your material in the vise, consult the following chart to avoid some very unpleasant surprises during cutting. Use shims if necessary. Make sure that your material is evenly supported along the vise jaw faces. Your material should be clamped down rock solid, no exceptions.

Grizzly G0561 Metal-Cutting Bandsaw

Instructions Before Use

  • It is absolutely required that the bandsaw operator has watched the “Setup & Operation” video linked at the end of this article before using the bandsaw.
  • Do not cut thin stock on the bandsaw. There needs to be a minimum of three teeth on the blade in contact with the material. Doing otherwise risks breaking the blade and fouling your work.
  • When clamping your material in the vise, consult the following chart to avoid some very unpleasant surprises during cutting. Use shims if necessary. Make sure that your material is evenly supported along the vise jaw faces. Your material should be clamped down rock solid, no exceptions.
  • Adjust the bandsaw speed relative to the material being cut. Mild Steel does NOT cut the same way as Stainless Steel. Consult the following chart from Grizzly for parameters:
  • When cutting, pay attention to the chips being produced and compare to the following chart. Adjust machine operation until the proper chip form is attained.

Usage/Guidelines

Power-up

  1. Apply PPE.
  2. Plug in torch and work clamp into appropriate terminals for your operation. Plug in foot pedal for TIG.
  3. For TIG, open the gas cylinder valve slowly and completely until the valve stops at maximum “open.” Ensure at least 100PSI in cylinder.
  4. Power on using the blue switch on the back of the chassis. For TIG, set CFH on flow regulator to (rule of thumb) 2x the cup size # on your torch.
  5. Install sharp and clean tungsten, attach work clamp, knob in the correct settings, go.
    1. Big note: The AC balance knob selects the % time spent in electrode positive state. It’s unlikely you’d set this higher than 40%. This is an inversion of what TIG operators of other machines may expect.

If any of that wasn’t crystal clear, don’t touch until you attend training.

Power-down

  1. Power off, unplug.
  2. Close the dang cylinder. Gas is money.
  3. Clean and sharpen all the tungsten you used.
  4. Neatly store cables and relevant welding tools on cart.

Hakko Solder Stations

Overview

Denhac has two Hakko adjustable temperature soldering stations, one older with a knob to set temperature, one newer digital. There is also a Metcal suitable for finer detail work with it’s own wiki page.

After reading and understanding this page, you are authorized to use them.

Setting Temperature

For tin/lead solder, 600 ℉ (315 ℃) is a good starting point. For lead free, 700 ℉ (370 ℃). It’s OK to turn it up a bit more, but keep it below 800 ℉. Higher temperatures will degrade the tip quickly. The older iron is ready to use when the red light is no longer solid. The digital one displays actual temperature as it warms up.

Cleaning the tip

The soldering iron stands have sponges. Wipe the iron tip on a wet sponge, there is a bottle of distilled water available. There is also bronze wool that can be used. These are the only two ways tips should be cleaned.

Safety

  • Don’t touch the metal parts of the iron until cooled sufficiently. They will cause severe burns.
  • Safety glasses are advised. You don’t want molten metal in your eye. Solder can splatter as a connection is pulled apart.
  • Use the fume extractor fan. Place it near the work, you should be able to see the flux fumes being pulled into it.
  • Most of the solder contains lead. Wash your hands after handling, keep the work area clean of solder particles. Denhac stocks lead free solder (AIM REL22) which you may choose if you wish to avoid lead.
  • The soldering iron should always be either in the stand or held in your hand. Never set it down elsewhere.
  • Turn off the soldering iron when leaving the room or not using for more than 10 minutes. They heat quickly. Turning them off also preserves the tips.
  • Keep the area around what you are soldering clean and clutter free. The soldering iron can ignite paper and some other materials.
  • Stabilize your work. Helping hands and a stickvise (great for holding small circuit boards) are available.

Proper Use

  • The soldering tip is not to be used as a pry bar. Only light pressure is necessary. The tips have a copper core and thin iron plating. Once the iron is cracked or worn through, the copper will begin to dissolve into the solder.
  • To do: find a good how to solder video, add link
  • Be a good neighbor, leave the tip tinned and clean

Metcal MX Solder Station

Replacement tips are $25. Please don’t scrape or pry with them. Use the other solder station if you are in doubt or new to soldering. See the Hakko wiki page for safety, tip cleaning information. After reading and understanding both of these wiki pages, you are authorized to use it.

Setting temperature

Temperature is set by the tip cartridge:

  • STTC-5xx: 500 ℉
  • STTC-0xx: 600 ℉
  • STTC-1xx: 700 ℉

The Metcal MX is an RF heated iron, powered by 13.56 MHz AC. The tips contain a tiny induction heater. The part being heated by that has a curie point (temperature where it stops being magnetic) at the temperature rating of the cartridge, so it quits heating at that point.

Changing tips

Do not remove tips with the power on. This can damage the power supply. The ideal way to change a tip is with a silicone hot pad. Alternately, pliers can gently be used on the part closest to the grip (not the actual soldering tip but the stainless steel tube). In either case, pull the tip straight out, place it somewhere heat resistant. Insert the new tip by pushing the tip against the rubber soldering mat to fully seat it.
