|Make/Model||Jet 1442 headstock, and 1642 bed (probably)|
|Contact||Wood Shop Area Host|
|Host Area||Wood Shop|
This is an oddball lathe that seems to be assembled from a collection of parts from other lathes.
- The bed and legs are from a No:1642 16" electronic variable speed lathe.
- There was a dataplate on the legs to this effect, but ALL the information on it was wrong (swing, working length, speed control type, etc.) for our lathe configuration, so it was removed
- The headstock and tailstock are (we think) from a 1442 MECHANICAL variable speed lathe
- manual here: File:Jet 1442 lathe.pdf
- The tool rest is fairly large for the headstock height and ~probably~ originated with the 16" lathe parts
It spins, it works, and serviceable tailstock and headstock parts are on hand. Don't change the speed - the speed-change mechanism is broken and also jammed in place.
How To Get Authorized
Authorization for this tool by authorized proctors only: Authorized Proctors
We try to say "authorized" now at PS:1 instead of "certified" because we aren't saying you're an expert after authorization, just briefed ... There is a list of authorized proctors (trainers) right here. You can't become authorized from just any other member who knows how to use this tool, it's a dangerous piece of equipment and we're keeping the authorization process a little more formal because of that. Ask the area host for the wood shop, any volunteer authorizers for wood shop, or the people listed as authorized proctors about authorization.
This tool requires certification for use. Please contact one of the following to arrange authorization.
- This list is a basic starting point pending approval of the area host.

Personal Protective Equipment
- Face shield (not just safety glasses) must be worn.
- Long and loose hair must be contained.
- Do not wear gloves or loose clothing.
- Remove watches, rings, and other jewelry.
- Roll up or don't wear long sleeves.
- Dust protection may be required.
Pre-Operational Safety Checks
- Locate and ensure you are familiar with all machine operations and controls.
- Ensure all guards are fitted, secure and functional. Do not operate if guards are missing or faulty.
- Workpiece must be securely fastened to face plate, chuck or between centers.
- Rotate the workpiece by hand to check clearance between tool rest and bed.
- Ensure the cutting tools are sharp and in good condition.
- Start the dust extraction unit before using the machine.
- Make sure all clamping handles are tight.
Operational Safety Checks
- Adjust speed to suit the diameter of the work and turning operation (IMPORTANT - *never* adjust speed while the lathe is off!)
- Before making adjustments (apart from speed), switch off and bring the machine to a complete standstill.
- Keep the tool rest adjusted close to the work and at the correct height.
- Stop the lathe and remove all tool rests before sanding.
Ending Operations and Cleaning Up
- Switch off the machine when work completed.
- Return all chisels and other tools to racks.
- Leave the machine in a safe, clean and tidy state.
- Sweep or vacuum any wood debris/dust/shavings.
Potential Hazards and Injuries
- Please watch this short safety video on YouTube 
- Eye injuries from flying debris or defective timber. Wear appropriate eye protection.
- Hair/clothing getting caught in moving machine parts. Remove jewelry, loose clothes, keep sleeves short, roll up sleeves, no gloves, secure long hair
- Airborne dust. Wear a respirator or dust mask appropriate for the material you are using.
- Smacked or cut/impaled by a gouge. If you don't maintain a good stance and a good grip, a tool can go flying.
- Wood shrapnel. Occasionally, the workpiece can explode. A face shield, an apron, and working slowly with sharp tools can help avoid this hazard.
- Rough cut the workpiece as close as possible to the finished shape before installing it.
- Check your workpiece for flaws, cracks, knots etc. and test glue joints before mounting the workpiece on machine.
- Use the lowest speed when starting a new workpiece.
- Drive the workpiece into the drive center while the drive center is in the headstock.
- Touch your project by hand while the lathe is running
- Set the drive center into the workpiece with a soft mallet prior to installing it on the headstock.
