This quote just about sums up Versalab! Anyhow, count me in for what it's worth. I was lucky to stumble across this post and since I doubt versalab will be proactive in e-mailing past customers I hope I remember to check this thread.. :idea:

Danty, if the error - misalignment - is large then you can see it. But modern thinking is that errors over a few thousandths of an inch, which is hard to see, depending on which orientation it is - can cause flavor problems.

We have spent considerable time thinking about the alignment equipment and what items are necessary.

There are many ways to get a kit together. We would like customers to comment about how they would like to go about this from a price point of view and even what process to use. There are a few items that should come from us - the instructions and the plastic feeler gauges mentioned below. The instructions can naturally be emailed and the feeler gauges fit into a letter envelope.

Our preference would be for customers to go to Amazon or eBay and purchase the equipment directly themselves. This isn't exactly what we said we would do - provide a kit - but the price /quality decisions must vary considerably from one customer to another.

How would you like to proceed?

Components

Magnetic stand - such as this https://www.amazon.com/dp/B01BHHYCVC/

Lever type dial test indicator - such as this https://www.amazon.com/T%C3%BCrlen-Prec ... 0043F4YLO/

Feeler gauge set - such as this https://www.amazon.com/Stanley-Proto-J0 ... 001HWDOK8/

Optional is a torque wrench and several hex sockets. While we will give torque specs for two different bolts, not everyone will be comfortable estimating these and may prefer to purchase a torque wrench.
Such as this https://www.amazon.com/EPAuto-4-Inch-To ... 01LX4ND65/
Or this https://www.amazon.com/eTORK-8-Inch-Tor ... 07BYC1V9Y/

And the sockets such as this - https://www.amazon.com/Professional-ALL ... 074LYY6Z5/

You will only need the 5/16" and 3/8" hex bits, but often it is cheaper to buy a set.

We will supply several plastic feel gauge strips to use to help center the bottom burr on the burr driver.

I have all the above (some more than 1). Except the plastic feeler.

BTW - really good machinist stands can be had for next to nothing on Fleabay. It also seems that vintage ones are of higher quality.

I agree about the stands, but all I am trying to do is give guidance to those who are less informed.

The originally suggested cost of $50+shipping was an important point for me. I'm not really interested in acquiring high quality equipment, I just want my high quality grinder perfectly aligned at the least cost. If not providing a kit, can you list the needed supplies from the least costly options? Something that does the job well, and only that job.

Another concern is shipping internationally; having different items shipped by multiple vendors is going to cost significantly more for someone like me who doesn't live in the US.

A $50 kit from you guys sounded soooooo sweet....I hope you're still considering it as an option.

I think what John is saying is that, for example, you can get a base for less than 10$ delivered from China. E.g. https://www.banggood.com/215mm-Height-M ... 28587.html Or a dial indicator for a wee bit more: https://www.banggood.com/DANIU-40112302 ... 57267.html

Since the base has a magnet, is a bit heavy, etc. If he were to buy it (probably at similar cost, he won't buy the hundreds or more needed to get to a price break), he'd have to mark it up at least by the S&H fees. Also, it'll end up needing a larger box so USPS/Fedex/UPS/DHL will end up costing! So if John was able to put this together for less than 50$ delivered to Versalab (quite doable), it would probably double the price to ship it. Which will send it over customers/tax. At which point the DHL start charging their own handling fees. I think what he is doing is quite fair.

That is why I hated the belt. Getting it shipped to the Mediterranean was expensive. So I wanted to send two (halves the shipping cost each). But that exceeded the tax thresholds. Which added at least 20% to the cost and since customs didn't know what it was I had to go to them to get it released. Yuch! So I ended up buying one at a time or schlepp it through a forwarder. I may have been able to source it locally but couldn't spec it well.

I did the same building my 3d printer. Get all the motors, electronics and other stuff from China and only the printed parts from Europe/US.
The (abusive) Chinese post service make it such that splitting it into shipments so I don't get taxed was an extra benefit (here we have a 75$ tax exemption).

These below are the cheapest pieces that we have found. The minimum requirement is the indicator and stand and the feeler gauge set and two hex wrenches 5/16" and 3/8". I am assuming that eBay is available worldwide.

The wrenches can be bought here cheaply. https://www.ebay.com/itm/Allen-Wrench-H ... :rk:8:pf:0

Do not buy a folding set or T handle set. They will have handle the force necessary to loosen and tighten the frame and shaft bolts. Even with these you will probably want to make sure you have an 8" or so long pipe to slip over the wrenches to give enough leverage.

This stand is $21 and change. This is a stand and indicator both. You will need to fiddle with the connection between the two - being the cheapest Chinese stuff, which is why we gave directions to more expensive equipment. The combination of the stand and indicator need to be able to reach the seat of the bottom flat burr on the burr driver.

https://www.ebay.com/itm/Universal-Flex ... 2749.l2649

A feeler gauge set needs to ideally have everything from .002 (or less) up to .030" or so. They can be bought for under $7.

Will you be posting a video or directions on how to check the alignment?

Absolutely. Most likely it will be on our website versalab.com.
