Finishing valve seats on today’s multi-valve heads
One of the most frequently asked questions on our tech line today is: “What is happening to my valve seats? I’ve tried everything! A new stone, stone holder, pilot and even a new dressing diamond but I can’t achieve seat alignment.” Get some ideas for how to finish valve seats in multi-valve heads.Tips and tricks for fast and accurate crack detection
Dry Method Magnetic Particle InspectionWhen “Magnafluxing” a casting, never blast with media prior to testing. Blast media peens the surface and can move metal, possibly closing the very cracks or flaws that you are trying to identify. When very coarse wire brushes are used roughly, they can also mask these areas.

Carbides are more brittle than high speed steel, so it is very important that they be used with care. There are three things to remember when using carbide cutting tools:
- Avoid making intermittent cuts
- Do not turn tool in reverse of normal rotation
- Avoid cutting out valve seats with counterbore seat cutters
When in use, always keep carbide tools stored separately, cased in wood or plastic. If they happen to bump into other tools or machine surfaces, the carbide could chip, thus destroying the integrity of the tool. Tool Boards can esily help revent tool damage. Your Tool Board will enable you to organize and separate your tools for quick selection and safe storage. Some machines are already equipped with a Tool Board. If not, take some time to construct your own. Your productivity will automatically increase and your carbide tools will be stored safely and properly.
Performance Angle Milling
Q: What is the proper way to angle mill? Should I change the intake side or the head or change the intake? Get the answers from the Goodson Techxperts.Solutions to common cylinder honing problems
Get solutions to the most common cylinder honing problems including stone loading, cylinder taper, uneven wear, chatter and more.
A New “Finish” in Honing
Plateau hone, soft hone, whisker hone and ultra-finish hone. Confused? Don’t feel bad… there are many machinists out there who are uncertain about this new honing method. In fact, it’s one of the most frequently asked questions on the Goodson Technical Service hotline.
For years, we have been honing cylinders with a coarse stone followed by a finishing stone. Then ring materials changed, requiring an additional very fine finishing stone to follow. Now current technology demands an added step to create an even cleaner, burr-free finish.
Hearing protection in the workplace
The Occupational Safety and Health Administration (OSHA) estimates that ten million people in the United States have noise induced hearing loss and nearly all of those cases are a result of exposure to noise on the job.
Unlike muscles, you cannot “toughen up” your ears so that you’re not bothered by loud noises.
