IMHO, playing with the lead from an old battery just to kill resonance?

Not worth it man. Just buy some lead shot if you really want lead, or find an alternative.

[nervewrecker]

I might use a bit of mdf in it but I am contemplating the cement & lead still. enclosure needs to be as dense as possible.

[nervewrecker]

so what do you mix the concrete with to apply? normal resin (with our without the hardener / activator thingy)?

[MONGO]

^^ i say so too..

[nervewrecker]

shoulda jus build a normal MDF box yes

when I get a flat tyre you coming to lift the box for me to get the spare out?

[nervewrecker]

so what do you mix the concrete with to apply? normal resin (with our without the hardener / activator thingy)?

or cement & water?

yea, I know its a pretty dumb question.

[nervewrecker]

i'll put it on the hood. 1raj.

[nervewrecker]

white oak & water.

[nervewrecker]

its on the table at the back of the house, filling it with water will give me an average volume so I will know what height I am working with.

how to: fiberglass / cement / lead shot

[nigel1977]

Nice find. That's my team mate Mike Peterson.

[nervewrecker]

When I came across that link I was almost positive I made a mistake in the mixture as 2 days had passed & it had not cured as yet. The previous test mixture was approx 1/3 cement & 2/3 resin, it turned out fine but took about a day to cure so I had not lost hope about this one.
I used close to a 50 : 50 mix of cement & resin, it gets pretty thick & takes long to dry but it gets the job done. I used a slightly different one (approx a 40 : 60 or 30 :70 cement to resin mixture) to apply kitty mat & I am using the 50 : 50 mixture between ever 2 layers. The end result looks sexy

I really got the ingredients from DK though, the mixture part I wasnt too sure about.

[evolution7tt]

Correct me if I'm wrong here.. the curing time on the piece will not depend on the amount of cement you add, but the volume/ ratio of hardener.

[nigel1977]

^^ that sounds right.

[MonsterPower]

oye nigel find out a fast easy way to make lead shots and i may have a couple batteries i can help out with ..


wanna do a lil project on the wifey car

[nervewrecker]

^^^

I dont think I wanna play with that lead now that I am older & smarter so I know the helath risks of playing with it.

[nigel1977]

i can provide some batteries. what ideas do you have for the pellets?

I had the pleasure of judging this car for both install and sound at Canadian Western Finals a couple weeks ago. A very nice install, but there's a lot of small flaws in the work. Very technical install. Has the ability to have a preset EQ for each track.

was casing youtube for lead shot maker and came up with some interesting finds

this was one in operation ...

heathydee shotmaker is what it is being sold as

[X_Factor]

^ whats the purpose of using the lead shot?

[nigel1977]

ok u hv my interest piqued.

Lets do this. I need a couple pounds. I'll start hunting for tire weights in the mean time.

[nervewrecker]

^ whats the purpose of using the lead shot?

I think to add density & decrease the resonance.

[nervewrecker]

Isnt the lead plates in the wet cells a like lines on a graph page just they are about 1 - 1.5mm thick & each box is like 1/4" - 3/8" a side length?
Why not lay them down on a flat surface & use a heavy piece of metal with a sharpened side to cut it up?

[MonsterPower]

somehow i dont think the lead sheets will have a better adhesion to the surface as the shots which is integrated into the surface.. its like using pieces of tiles to plaster a wall rather than sharp sand ..

[nigel1977]

because pellets are cooler.

[X_Factor]

melting down an old battery is stress...did that a couple times before and wont ever do it again....almost half turns out to be unusable

u all are better off buying lead sinkers used for fishing or nets and melting those instead
those are alot more easier to melt and it basically melts pure with little rubbish on the top

actually u all can check out the smallest size ball sinker or jig weights at any tackle shop and see if those can work for you instead of playing with lead!

[nervewrecker]

I see some of those tyre shops have lead weights that they have removed....I dont think they use them back.

[nervewrecker]

what do you guys prime with before painting?

[nervewrecker]

what do you guys prime with before painting?

I see there is a lack of pics so I have decided to grace you guys with some.
This is my repair project to my old grill but can I have some assistance guys, need to prime & paint this:







making the mould out of modelling clay & foil:















attached, resin & kitty mat added:




















this is my second try & fiberglassing so please dont bash me if it didnt come out good guys. I am open to corrections & criticism.

[nigel1977]

Awesome attempt. That fiberglass is not going to hold on the paint, that's on the original plastic of the grill for very long.

There are some prep steps that I didn't see you do, or see evidence of it being done, that would have ensured a stronger adhesion of the resin to the plastic.
