The first two pics are of my 45 degree miter jig for my radial arm saw. I t is easily unclamped and removed from the table.

The last three are of a vibration dampening box for my garage sale scroll saw. What an improvement! 2 ” of clean sand is sandwiched between the saw base and box. Plus it allowed me to level it on my tilty countertop.

Thanks for looking!

Both of those are really smart ideas!

This sounds interesting. On the scroll saw, the “top” of the box where the saw is attached, floats within the box and sand? If it floats doesn’t the sand tend to vibrate up between the top’s edge and the inner walls?

I’ve done vibration dampening on a small Jet lathe and two 35 gallon barrels almost full of clean sand (~650 lbs), but the lathe was securely fasten to the tops of the barrels via a pine counter top. Worked great to help kill vibration.

I never thought of doing this for my el-cheapo scroll saw. Sounds like a real good idea.

Dave ~ It is new, less than an hour of actual use, but I haven’t noticed any sand coming out. The three bolts come through the bottom of the box, sand and sub-base of the saw and securely tightened down. There is less than a 32nd of an inch of area around the edge of the floating sub-base.

That’s a great idea…as for sand coming up onto the platform, some kind of rubber gasketing around the edge might help. Could the dampening also have been done with rubber cut-outs from old tires??? Just wondering.

I like your miter jig. We just recently got a radial arm saw. Do you have any kind of plans you could share for it?

Well thought out, both are excellent solutions.

I was looking for noise reduction for my scroll saw.
You call it vibration dampening….maybe better.

I read the text above and the comments 4 times. Still looking at the pictures…. :)

I stil don’t understand how the construction is built. :(

Greetings and keep on going the idea-work.

Wow! It looks like several of us have scroll saws that could use some vibration dampening! I too hope you give further notes/pics of your box. So if I understand correctly, you have the bolts attached to the fixed bottom of the box, a 2” deep layer of sand is added to the box, then a “floating box top” is put on the top. Now does that top have a real tight fit around the bolts or do you have a < 1/32” gap there as well? Great post!

Sounds interesting. I have the same question as Sam. I’d like to know more. Would appreciate a longitudinal section sketch, even a rough one. Thank you.

Thanks to all for getting this post into the daily top 3.

Barry ~ I think the densely packed sand absorbs vibration better than the rubber tires would, but I don’t know for sure.

Tru ~ I just kind of “winged it” as I went along. It started as a triangular base with a 90 degree corner for the front edge. I added the fences, braces and clamping bar to the bottom. Every saw has a slightly different table clamping mechanism. It is accurate and gives a perfect 45 degree cut every time.

BasHolland ~ Sam (above) has got it.

Sam ~ Yes, I allowed a little play around the bolt holes in the floating base, as “play” for getting the saw mounting holes lined up. Still no sand coming out.

EMVarona ~ I wish I had time to do the drawings. It is pretty straightforward though. You just want the floating saw base to be firmly clamped to the bed of sand.

Just wondering since there is a little play around the bolt holes combined with the tightly clamped floating base, (just thinking) is it likely that the sand would eventually migrate through the space around the bolt and eventually settle above the floating base? I plan to do this with my Makita scroll saw so I am very interested.

Again, just thinking, following the principle used in the construction of railroad tracks to minimize vibration, they use gravel rather than sand. What’s your take on this?

Ed You can just put the sand in plastic bags or boxes. I have my lathe weighed down with sand that is still in the original paper bags. I think sand is probably heavier than gravel, so more effect for a given load.

So far, no noticeable sand has leaked out. If it does, it only takes 5 minutes to unbolt it and add more. Some plastic wrap might be a good idea, but I don’t think necessary.

BTW – I used “leveling” sand which I think is coarser than the fine sandbox sand, bought at the big box.

For projects like this that have close afinity with one’s situation like mine, ideas keep on popping up. I lift weights regularly. I have a set of dumbells and a barbell here and some extra weights. Come to think of it, the weights could be very useful. Furthermore weights are easily available.
