Hello,

Would like to Ohm out some DC brush motors on a 1991 VF1

Does anyone know the specs? or the Wattage the motors are rated at.

Thanks

Found a old 1991 VF1 locally ,its not in bad shape but does have a Com board problem
But the machine works. Just have to enter the programming manually

This will be my first CNC machine, after...

Gees, I havent been on here in two years and glad to see this thread is still
going strong.

3000!

I am sorry I had to do it.

I am going to cheat

Anybody going to Cast Expo in Atlanta?

I am locall to the area so I am going.

How about this theory,

The wetter the better? , Epoxy rich mixture to ease in mixing and also will let the air out
better, then the vibration compaction is where you get your packing density and...

The science part I will leave up to the smart guys :-)

You tell me , Put this many rocks in this bowl, this much epoxy in this bowl, then put
them in this bowl and mix em up , then put it in that...

The thread seemed to be stalling a little, so I am glad my posts fired it up
again :-)


This thread has had my attention more than anything I ever had
interest in, I just wish the $$ was around...

Yea, have you seen how big some the machines are that they are building?

Some guy is building a huge lathe with some sort of milling
quill attached.

There are so many posts on that website and...

thanks, Yea that one works, its trying to go into a forum
that has to be signed into, somewhere the security gets
messed up with the password, i'll just have to learn German :-)

this is the one...

I've been looking at the German CNC site that has
been referred here in the past, HOLY SMOKES! those guys
don't fool around.

I went to the 2006 show

AMAZING!!!!

but disappointed I missed out on meeting Norm Abrahm......


Will try to go again 2008, also coming up is the metal casting convention
early 2008

I wonder if this post would qualify for the longest lasting forum post?

Can't believe its been going on 3/4 of a year....

Though it seems to be slowing down a bit.

Anybody else build...

I just remembered these guys.
I bought High Temp epoxy to mold some carbon fiber

Concrete vibrators, good website if you also want to cast your own
concrete countertops.

My light sand is Pavestone brand filter sand gotten at the Depot.
Very clean out of the bag, but wet so I had to dry it.

I will probably use the same, add chopped fiberglass fibers
and up the...

Here is another thought.

Up the resin to 15% by volume.

Add chopped fiberglass fibers to the mix.

Parked the car on them. Figure 800 pounds each tire.

Smashed to pieces with a hammer, car did nothing to them.

Did not take too much effort to smash them.

Ok its been a week since I made my mad mix :-)

Tomorrow I will destroy my bricks. ANd they sound like bricks when you
tap them together.

Nothing scientific just going to bash the H*** out of...

Before I do my destructive testing :-)

Just remember easiest way to remove an old iron bath tub
is to bash it with a sledge hammer to break it up.

I was actually beating the two together...

My black sample weighs more than the sand.

For the size of mine being appox 131th of a cubic foot
and it weighing about a pound I guess easily over 100 pounds
per cubic foot.

The sand bag...

Here are pics of my castings

10% Epoxy by volume ratio, granite paver base dust-fines-coarse mix

Mixture was rammed into mold.

Hi,

Results of my 10% epoxy by volume mix experiment.

I have actually impressed myself. Might have gotten lucky and got it
right the first time.

The filter sand mix is super strong, I only...

Hi,

Jumping in on this ride :-)

I have been doing my own experiments, actually they are curing right now.

I have tried my formula by volume which works out to 10% epoxy.

Yes it is very...

Working on Polymer casting recipies as I type.

Hi,

I have the same engine lift fthough from Northern Tool
I bought it the day I needed to get my 12X48 Grizzly lathe out
of the moving truck when I moved. That thing weighs about 1000 pounds....

Well , hopefully by word of mouth.

Advertise ,or actually go to the bigger shops
and see if they have work they dont want or not economical
for them.

Believe me I wouldnt be quiting my day...

Well it does not look like it is going to happen
for a while .

I am in the middle of moving to Central FL
and buying a house.

I planned on doing work for my own project and hopefully...

Is it possible you have the galil card or somewhere
in the configuration set to Stepper?

Are your servo drives PWM or analog?

If you have it set to stepper it may just be showing
open loop...
