Technically, my labor is free.  Whatever money I save equals my per/hr worth in a way.  If I run out of time in the day, I just have to wake up earlier and/or stay up later.  It all just depends on how what I do affects our home.  

The sliding tube and spring are rather ingenious.  I thought of making a mini tamper setup with a hacked nutcracker (the lever style) on some sort of sliding track or some setup with a can crusher and some sor of scale.  Someone sent me a link to a home made press, but I need something a little more low-tech (read cheaper and wih items I can find in Dave's shop and Harbor Freight.)  

I would like to do this, so if you think it is at all feasible*, I can start a new thread.


edit: *and interesting

In the tube I was going to put a calibrated spring with 30 pounds of resistance, thus when you felt the spring "give" under the ram, you would have 30 pounds of pressure on the puck.

Posted July 19, 2010 link

If the spring buckled at 30 pounds of force, wouldn't you then have 30 pounds + the tamper weight + 1/2 of the spring weight on the puck?

30.6 pounds of force is a dramatic difference from 30 pounds.*


The can-crusher is a splendidly clever starting point.

MarryAnn, the hard part is done with getting the idea for the device, the details are not such a big deal.

Any device that has a ram that goes straight up and down could be used, the only limiting factor would be the available space in which to place and use said device.

Look around at what is available to you. It need not be industrial quality machinery just some thing that can handle 30 (or so) pounds of pressure.

An online catalog to get ideas from though some of the items can be a little pricey is
http://www.mcmaster.com/#

I would be happy to help in any way I can. :D

Wayne, MaryAnn, in requiring the operator to lift his/her arm and apply pressure to the tamping device you're dreaming up, you haven't gone far enough.  Have a look here:

 Versalab power tamper

You sound like you think you've got this all figured out, but as the above illustrates, those may not be laurels you're resting on.  Have you considered nuclear power?

(BTW, I saw this device and the company's grinder in action a while ago.  No, MaryAnn, there is no permanent cure for upgraditis... something else always comes along, and probably always will.)

Mark the only issue with the the versalab is the price. MarryAnn wants to make something much less expensive. I know your post was in jest but there are real benefits with a press, I have a manual tamper and used it for a long time before getting the press and I can say that the press is better and much more consistent, and consistency is what we are after....NO?

It was almost entirely in jest.

I'm envious of your Presspoint but can't bring myself to spend ~$300 on a new one (or the Macap, either).

Maybe when MaryAnn gets hers figured out she'll go into production.

Nice MaryAnn.  So, applying very high pressure AND twirling with a drill chuck is the ticket to a great puck... I knew it could be easier.

I'll wait for serial # 0001 to roll off your production line.
