John,
Epotek make UV curable epoxies and are available in UK at John P Kummer Limited

The type of process defeats the purpose of E/G this being vibration damping.

Jestah,
It would be hard for me to confirm proportions of the items, not knowing the sizes and proportions within them, however one of my concerns is the 14-22 mm item: it is usually recommended the...

The original Moglice formula was patented and the recipe details are included.

Herbertkabi,
I believe this product is urethane.

I like the product's viscosity

Cameron,
Have you tested your samples, I'm curious to see what the results will be on them.

Best regards,

Welcome aboard ClockMakerDK,
I can't wait to see the pictures!!

Hi John,
"Intuitively" I believe you are on the right track in using a mix a "moglice" type blend for friction for the ease of binding the strings. The other important aspect that needs to be...

Roman,
you are right there is close to 30% epoxy by volume in the mix at 8% by weight it's close to 20% :eek:

The centrifugal mixers are pretty impressive indeed. I believe i've seen a video a...

Roman,
we discussed this a few thousand posts back(post 3323), interesting piece of equipment, it what suggested by someone when greybeard was working on his spincasting project. The capacity (800g)...

This what I have, I can mix a full bag of concrete mix at a time with it:Power Tools, Woodworking and Metalworking Machines by King Canada

Nice Samples Guys!!:cheers:

Cameron,
I am really not sure that mixing in excess resin is the way to go. This process needs too much waste and or cleaning. However I like the idea of placing some kind of membrane between the...

Cameron,
There is something I don't quite understand, I'll try to put it in perspective:

Consider round particules and crushed particules of the same density.

The information provided by...

Cameron,
go back to post #3971, the Scott Baden video shows mixing equipment than can be easily replicated using 5 gallon plastic pails. The beauty of the machine is that the mixing blades do not...

Cameron,
ship that snow up here where it should be.

We've hardly had any snow since christmas.

Cameron,
This effect is directly related to the type of epoxy and it's viscosity. a very low viscosity epoxy (100CPS or less) will reduce the probability of getting a zero layer at contact points,...

I believe that voids left in the mix are most likely due to epoxy viscosity, the lower the viscosty the less air entrapment and ... the less voids.

osiervt,
How many aggregate sizes have you used? what proportions?
What is the epoxy content?

You could use Fuller's algorithm to somewhat improve your mix. Fuller will not bring you to an...

Gerry,
The reason you did not get any exotherm is that all the heat was absorbed by the sand.

My wife and I were playing 4 hands on the keyboard!:D

Seriously, for once I didn't want to write mispelled

Hey John, nice to hear from you!

I thought that a jug was an old imperial unit of measure!

Your right about edges , Zanite uses a mix with smaller aggregates and line the whole interior of...

Nice work CR,
I like your idea of the DB9 connector soldering stand, it's like the rest of your work:
simple and efficient.

Best regards

Bruno

Copper is often used in factories in our part of the world, but nowadays instead of soldering the fittings together some plumbers will braze them.

Roy,
Ok for vibration, directionnal? I guess Thomas Zietz would not agree with you!
None of his setups were/are directional.
Vibrating motor and isolation rubber costs, come on, with a little...

Romanlini,
I do not consider making EG very fussy. There are different ways of making EG, in the german forum for instance, members have used of the shelf Epoxy without degassing agents or any...

Diyengineer,
Do you have a part number of what you are looking for?
Have you tried Mouser and Digikey? Mouser sells Honeywell, Omron and microswitch products

Romanlini,
I allways like to see these photos,that's the avenue I want to go!

There are many drawbacks in drilling holes and setting inserts and suport plates after casting:
1-The use of special tools for drilling
2-Handling of a >100 lbs casting vs lighter and smaller...

Osiervt,
Interesting project!

I have a question:
Why is the gantry made out of MDF and not EG ?

And a few remarks:
The support plates should be embeded in the EG casting and held by...

osiervt,
You can get all the aggregates needed from Agsco including zeospheres in USA.
