Q1: I have a VST basket. What size tamper should I buy?

For any VST baskets, we suggest a 58.4mm base for the either the 5 Star Pro or Original Eazytamp.

Q2: How can I measure the size of my filter basket to work out what tamper size I need?

There’s a few ways you can check the size of your basket.

If you have a vernier caliper, you can use this to measure the inside of your basket. If you don’t have one of those, you can measure the size of your filter basket by cutting a business card so it fits inside the basket across the widest section, then measure the size of the card.

You could also check online to see if your coffee machine manufacturer publishes the basket dimensions for your model. Alternatively, you can use our measuring guide to check what size you need (opens in new window).

If you use a variety of filter baskets or coffee machines that have various basket diameters, we recommend you purchase bases that would suit those models, which you can interchange as needed.

You can review the various options on the product pages of our site. We’re happy to discuss more details with you about base sizes. Please note however, that customers bear the responsibility for the correct choice of base size.

Q3: Can I order a base size that isn't listed on your website?

Yes – we make sizes between 49-60mm in diameter. If you need a size that isn’t shown as an option, please discuss with us prior to placing your order, and then record your selection in the notes section when you check out of our store.

Q4: I received my tamper, but the base has superficial scratches on it. Does this affect the coffee extraction when I use my tamper?

No. The small markings on the base of the tamper are just part of the manufacturing process. Every tamper will have a mark of one kind or another because it’s stainless steel. Our stainless steel bases are machined using a lathe, and when they come off the lathe they fall into a basket that contains other bases. As they land inside the basket they might mark. These markings don’t interfere with the quality of the tamping and make absolutely no difference to the flavour or consistency of the extraction.

Q5: My handle has lines marking around it – particularly near the top. Is this normal?

Yes – our acetal handles are hand turned, not injection moulded. These lines are a normal by-process of the manufacturing.

Q6: I received a red and blue spring with my package. What are these springs for? Do I need to add this to the tamper to make it work?

Each tamper comes with a specially calibrated silver 15kg spring already installed inside the tamper.

We also include a complimentary red 10kg spring, and a blue 7kg spring. These are provided in particular for home baristas who might have older style domestic coffee machines with non-commercial internal water pumps, that might not be as powerful as newer models. We provide this spring so it doesn’t undermine the functionality of the coffee machine.

If you’re using the tamper with a commercial coffee machine or newer model one-group machine for home use, we recommend you use the 15kg spring.

Q7: How do the pre-calibrated pressure springs work?

When the springs are inserted into the assembly, they’re placed under pressure. In order to achieve the pre-calibrated pressure, the spring travels 3mm inside of the tamper assembly.

For example, when the 10kg spring is installed, it’s placed under 7kg of pressure. As you push the handle down, the spring travels 3mm. When the handle meets the base of the tamper, the spring has compressed 10kg of pressure.

The same science applies for the 15kg spring. When that spring is installed, it’s placed under 10kg of pressure. As you push the handle down, the spring travels 3mm. In that instance, when the handle meets the base of the tamper, the spring has compressed 15kg of pressure. Between these two springs, it’s possible for you to compress anywhere in the range of 7-15kg of pressure if you desire.

Q8: Does the spring ever need to be replaced in an Eazytamp?

Some people ask the question as to whether the spring in an Eazytamp needs to be replaced from time to time, as they may wear out. In all the years we’ve been manufacturing since 2005, we’ve never had a request to change the spring.

The reason why this is, is because the spring is always under tension when it’s in the tamp, so the movement is only 3mm. The equivalent for someone that doesn't understand the science  it's like having a Mack truck spring on a VW car. It will never wear out.
