New life to a old hockey puck

<< < (2/3) > >>

NeoTech:
I have hockey pucks u nder all my machines just not thought of making a small stand for em like that.. wonder if they can handle the shaper machine as well..  *googling where to find used hockey pucks*

SwarfnStuff:
Thanks for the explanation Pekka. Now I am more educated than previously, well, regarding hockey pucks as machine leveling feet anyway.

No problem Swafn'!

I have two dubious experiments here...contary my habits, but least I can test two permutations on one go!

1) I'm trusting carriage bolt dome and washer to conteract floor tilt. Downside is that if the grinder jumps, it might land on atypical attitude on floor....I might need to build a retainer. I would bolt shaper on floor or use a big board under and make holes to pucks with a hole saw or something.

2) Differential nut here trades stroke to ease of adjustment. It should allow 16 mm of nut movement (8 rounds), that translates to 2 mm of carriage bolt movement...I felt that 2 mm of lift per revolution is fairly difficult for leveling (least if you have more accurate that carpenter's level). I might have gone other extreme with 0,25 mm/r resolution, but that was possible with standard taps/dies I had.

Threads are far from perfect, but this does not depend accuracy on dial reading, therefore I felt that thread accuracy (lead accuracy and clearance) is no issue here. This is not a way to make a lead screw or micrometer.

And one ugly rough adjustment one. I Should have made it more simple, but I could not help myself.

As a retiner, why not just a small dab of silicone?
