Yep, I'm doing another one, MT 18 as usual!

Work in progress? Car partially underway? If you want a spot to dedicate to the work this is where you'll want to go.

woah!!!!!!!!!! my face if red from fumes.

Postby Member02 » Tue Apr 17, 2007 6:59 pm

I swear, my body absorbs these resin fumes, I wear a mask, and my skin is visibly red everywhere open, I have this line from the mask of white skin meeting red skin.

anyhow, I added one layer and two layers in a couple spots (would've done more but I didn't make a big enough batch of resin)

this time I took the trouble of taking off one glove and taking pics, putting the glove back on, working, taking it off, taking a pic, and so on...

here's the sequence in order... I even added a picture of how much I cut in advance, and how I always cut oddball shapes and sizes, since I almost never do the same exact laying pattern.

tip: you'll notice if you looks closely at the oddly shaped peice going over the hump, it's been cut several times to allow it to bend around the bump without causing air bubbles.

Image

me sanding VERY lightly, to get rid of hairs that were sticking up (which was only in this tiny spot, thanks to the 'jabbing' method, I get a nearly smooth finish each time.)

Image


this is step 4 from above, simple to do, but helps a ton in keeping the mat down.
Image


this is what it looks like 'jabbed' by the brush in a couple spots...
Image



this is how it looks after I added more resin as needed while jabbing
Image


another spot:

more:

Corners are especially tricky, I find that getting the entire corner saturated before saturating the rest of the mat helps keep it in place, but it'll still move a bit, so take your time on these peices as they are important as well.

as you see above, it's getting somewhat thicker at around 5 layers overall, I'm surprised I'm not out of resin already, I'm guessing I can do what I've done today once more before I'm out.

Hopefully I'll have my US Composits resin in tomorrow or thursday. and the biaxial mat, which is how I plan to finish up the mold strength.

tomorrow I'm going to add yet more glass mat, and start planning out the baffle with dowel rods, and get everyone's opinion on that.

he does speak some sense, BaOH, or NaOH is usually around the labs for harsh spills, ie. 12+ molar hydrochloric and sulfuric, but they have these things called gloves that are the darndest things.... you spill acid on em, and you can take em off before it burns through. it's weird. oh, and the hypochloric/hypochlorous acid requires special handling, if you get some on you're skin you're SOL. besides ap chem shouldn't even be messing with hypochloric. the hoods in high schools aren't designed with that ventilation.



and now, to an on-topic comment.....
how many layers do you plan to do?
with a box that size and with that many curves, i would think it would be strong enough already.
And Shepherds we shall be, for Thee my lord for Thee.
Power hath descended forth from Thy hand,
that our feet may swiftly carry out Thy command.
So we shall flow a river forth to Thee,
and teeming with souls shall it ever be.
In Nomine Patris, et Filii, et Spiritus Sancti.

I don't think it is strong enough, I can easily move it around the flatter spot still, though the wheel well bump is plenty strong now.

but hey, you haven't seen the 18MT make a 150lb MDF box jump, literally 1" off the floor of a vehicle because 20hz made it move soo much...

I'm making this thing too strong.

No, but I, along with others here, have seen a certain 15" walk across a living room floor...
