I decided to go ahead and start a spinoff thread.  
"Do you blow on your puck?"

I was hoping after some brainstorming and practical discussion, we might be able to build a simple tamper.  

I have a can crusher on hand, and they are easy to obtain cheaply:
http://www.harborfreight.com/16-oz-can-crusher-46406.html

I figure maybe that plus a platform with a bathroom scale, and the presser fitted to a tamper piston should get me awfully close to my target.  I could put a recessed area for a basket into the wooden base.

Hope it isn't all solved and a waste of bandwidth....

Well, there are a number of click tampers out there in the market to tamp to a set pressure like this Espro Handheld Dynamometric & then the fully adjustable Concept Art Technic Adjustable Pressure Tamper from 18 - 46 lbs., not cheap though.

Some goals:

  • I want it to be very inexpensive  and made with common tools, so that future readers can repeat our (anticipated) success

  • an auto tamper so that people too weak to tamp 30 lbs the traditional way can use it

  • easy to make, again considering the future users.

  • maybe even a fun project

Will one of these fit in the bottom of your can crusher? If it does you can just screw a tamper piston to the top half and be done with it.

Good idea.  I think it might be just a bit too big.  107 mm is the diameter.  Will measure crusher soon.

Thought about the pull type scales and attaching to the top plate.  I have an extra here.

I answered you back on the other thread, anyway
a pull type scale won't work, well not in the normal way is is used anyway, as you would not be able to consistently get the length of pull right.

What I mean is, for one of these scales to work, each weight pulls it down a different amount from the starting point. Unless you rigged it up somehow to a moving BOTTOM PF holder so that the PF holder is free to move and is only restrained by the scale thus allowing the scale to gauge force regardless of the amount of movement of the PF.

The issue I see with the click mat is that it is solid. This means that your setup will not square the PF to the tamper thus giving you an angular tamp relative to the top of the grounds basket unless you are using a naked PF in which case the bottom of the PF or the grounds basket will square the PF to the tamper rig.

If you do want to use the can crusher as a foundation, you could cut a slot in the bottom so that the spouts can hang under the bottom of the crusher....... if it is strong enough to withstand the pressure after it is cut. Another way would be to put a raised platform on the bottom so that there is room for your spouts.

A tube in tube with a set pressure spring setup could be attached to the moving top part of your crusher with a mounting screw to mount your favorite tamper head on, the spring would regulate the pressure (until it bottomed out, then you just over ride it) the base would allow free movement of the PF for alignment.

Now you need a wall close by or need to make a stand to hold the setup in a vertical position lest the ground coffee fall out of the PF before it gets tamped while mounted sideways :P

Thanks Wayne.  I didn't want to bury the project in someone's thread and hijack to boot.  I like your idea with the spring.

Nice--thanks.  It was a juicer I saw at samsclub.com that made me think of this, but the juicer wasn't that cheap. I am going to go read that and see what juicers cost.

Thanks Randy!
