About Iven May

Owner Iven May

Owner Iven May

Hand carving and woodworking have always been Iven's hobbies.

In 1987, he began working for CNC Software, Inc., the creators of Mastercam. There, he spearheaded a new business model by creating an Educational Division - to sell software to schools, and to offer classes to help teachers implement the new software.

With more than 30 years in the industry, Iven’s career has spanned the entire Computer Aided Design and Computer Aided Machining process (CAD/CAM/CNC), and found its home in CAM. Iven puts his expert knowledge and experience to use, making tools for the industry he loves.

Over the years, Iven has assembled a top-notch shop at his home, which includes a full hot glass studio.

Why Hot Glass Tools?

On Iven’s 40th birthday, his wife Terri gifted him six glassblowing lessons. No one could have anticipated the intense love and passion Iven developed for the hobby. He quickly learned about the tools and in no time, Iven was producing high-quality branded stamps for hot glass, using his CAM setup. 

Today, Iven is the owner and master toolmaker at Leviathan GlassWorks.

If you have any questions about the product line, please reach out. Iven is always happy to chat.

Iven's Commitment to Customers:

"I have always appreciated a customer satisfaction guarantee. I make a great product and I stand by it. I want my tools and products to be the best you have used; I want them to put a smile on your face each time you use them. If you have problems with the tools, please reach out - your knowledge and experience help me create the best products."

Iven was born and raised in Washington, where he built his career and his life. He is a renaissance man with knowledge, skills, experience, and connections ranging all over the map. Iven makes friends wherever he goes because of his enormous heart (and a healthy sense of humor). He’s a dreamer, a maker, and a true craftsman.

I have used the services of Iven May and Leviathan GlassWorks for the past 8 years. He is an excellent machinist and does brilliant work. I find him very easy to work with - he listens and he understands
what you're looking for. He works incredibly hard to make sure that he realizes your vision. I would highly recommend Iven May for any of your machine mold needs.

Our Warranty

Iven's commitment to customer satisfaction

I have always been happy when a manufacturer offers a customer satisfaction guarantee. This means they produce a great product and they stand by it.

I'm not going to settle for just "satisfied"; I want to inspire customer joy. I want you to look forward to using the tools I've built. This means if you have any questions or concerns about my products, let  me know. I need your input to help make better hot glass tools for everyone, whether or not you buy the tools directly from me. Of course, if you use one of blocks as a mace at a renaissance fair you will probably win, but I don't think THAT is covered under warranty.

Our Warranty for standard use - Glassworking tools made by Iven May & Leviathan GlassWorks.

Leviathan GlassWorks guarantees your satisfaction while using Better Blocks, brass stamps, glass molds, and other glass blowing tools produced by Leviathan GlassWorks and/or Iven May. Our warranty covers all hidden manufacturing defects, and defects encountered under normal wear and tear when used properly.

Brass Stamps & Glass Molds

The client is responsible for ensuring there are no spelling errors and/or design intent errors - including the choice between stamps and brands - when reviewing provided proofs. Any mistakes should be reported directly to your point of contact as soon as they’re found to avoid delays in production and/or shipping.

Damaged or incorrect stamps may be eligible for replacement at a cost of $100 for sizes up to 2.5”, and $150 for sizes up to 3”. We reserve the right to determine eligibility upon arrival at our facility.

Please contact us to begin the replacement process.

Blocks

Better Blocks are covered for normal use in the glassblowing industry, for the life of the block head, as new heads can be attached once it wears out. Handles are guaranteed not to break off or come loose from the block head under normal usage.  Blocks will be a uniform shape and consistent thickness. Deviations from the above are eligible for replacement.

Blocks should be stored in water to ensure blocks don’t crack. Blocks that are stored in water and crack may be eligible for replacement. We reserve the right to determine eligibility upon arrival at our facility.

Used properly, Better Blocks are guaranteed to last longer than other blocks.

Please contact us to begin the replacement process.
