I had to make this a two part How-To cause of the number of picks. See part two after reading this section.



HOW-TO

FIBERGLASSING SCREEN AND GRAPHING IT INTO THE 98+ S10 DASH



This How-To is for those with minimal to above average experience with fiber glassing and or composite or two part chemical mixes and materials. Performing this mod will remove the center ac vents, the oem headunit position moving it to the ac controls position, and the ac controls going into the glove box.



The following How-To was generated by the buzz and interest in doing something of this nature but didn’t know where to begin. You take full responsibility of your own project and factory parts in performing this How-To and hold me not responsible. There are many way to perform this. This is how I did it.



Take good note of the photos, as they will reveal what the step explanation is. You’ll also begin to realize that the mod is an adaptation to other How-To’s found in the Sound forum with regards to fiberglass enclosure design. If you can do those mods, you can do this one.



If after reviewing this you want this done but feel its outside your capabilities or time, PM me and we’ll discuss me doing it for you for a minimal fee or parts trade to cover the material cost and some of the labor involved as it is a time consuming endeavor.



Step One: Where to begin? Purchase the screen you desire and take good measurements of the actual screen itself and not the screen and housing. You are only concentrating on the part of the unit that is visible.



Step Two: Sand the surface of the dash bezel as smooth as possible using 180 grit at first, and then transitioning to 220 and 400 grit. Grits lower than 180 are too rough and gouge the crap out of the plastic creating a greater headache. Scuff the area of the bezel around the center ac vents, controls and original head unit position with 40 grit paper. These areas need to be rough to make a porous surface for the adhesives to be used. Note, if you are doing this mod the ac controls will be mounted into the glove box. The second picture of this step shows the ac controls mounted in the glove box. After sanding as specified, use a dremel tool with router bit to cut the areas out as shown in the picture. Use a dremel tool drum sander to smooth up the edges of the cuts you make. Rough sand the backside of the bezel in this area as well using 40 grit paper.





Step 3: Go to a local Hobby Shop for RC airplanes. There, get the following items:


1/8” x 12” x 12” plywood


2 part 5 minutes epoxy


Micro-balloons (epoxy addative to make it pasty for filling or gusseting)

30” long half round stock (for framing the screen, picture will be further in the How-To)

Small saw blade and plenty of throwaway brushes

½, ¾ & 2oz fiberglass weave (NOT MAT!!!!!!!!!!!!!!! Never use mat unless you have a super flat piece you are fiber glassing or you have a boat hull.


Foam Electronic Wrap

1/8” x 1/8” x 20” balsa wood stock



Step 4: Make a template of the holes to be filled in the dash bezel and cut them out on the 1/8” plywood using a band saw or equivalent. Do not use a jigsaw as the blade of this tool will shred the piss out of the wood. Remember the wood is only for filling the hole with minimal structure properties. The fiber glassing will add the strength to the structure.





Step 5: Because there is a slight curve to the dash that a flat piece of plywood will have to conform to, epoxy the edges of the plywood to the plastic starting at the top left and working your way around it in three-inch segments. The plywood will curve to this and this is why a thin plywood is used.



Step 6: From behind the plywood, use a ½ oz fiberglass. ½ oz fiberglass is very thin like silk and will conform to curves extremely well. It can be found at the Hobby Shop. Lay down epoxy and the fiberglass using a stabbing motion to tuck the fiberglass into the nooks and crannies of the junction between the wood and the plastic. Do this all the way around like when gluing the wood in in the first place.



Step 7: Do the same to the front using 2” wide fiberglass tape found at the hobby shop. This now makes the wood very secure to the plastic by having made a fiberglass gusset on both sides of the wood.



Step 8: Epoxy in the cd player’s mounting bracket into the ac controls oem position. If it doesn’t fit, you might need to use a dremel tool drum sander to begin shaving away portions of the plastic cross piece of the dash that separates the oem ac position from the oem radio position.



Step 9: Like before when taping and gusseting the wood to the plastic, do the same with the head unit mount with stabbing motions, tucking the glass into the nooks and crannies of the junction from the front and back. Using micro-balloons to the epoxy mix, mix up a second batch after laying the fiberglass to partially fill in this junction. This will allow the gusset to properly support the weight of the cd player.

Step 10: Using the ½ round stock, make an exact picture frame of just the screen itself. Use the epoxy to join the parts together and micro-balloon mix to fill in gussets.




Step 11: Make an aluminum frame with the opening the exact size of the screen. Fold the flanges to a 90 degree angle. This will perfectly frame the screen and provide clearance on the other side for any buttons or adjusting knobs of the front of the screen that you want hidden. A picture later will demonstrate the clearance provided by this frame. Glue the frame to a hole cut in the plywood that’s the exact size of the frame. Then glue the wood frame made in the last step over the aluminum bracket. The next series of pics will show this. Note, use epoxy for all of this. Resin won’t be touched for a while. The flanges of the aluminum will be ¼” wide which will make roughly a 1/8” protrusion through the plywood.







Using a micro balloon epoxy mix, fill in any portions of the frame not meeting the slightly curved plywood base. This is obviously caused by the slight curve.

This picture demonstrates the aluminum flanges coming through the plywood base making a 1/8” protrusion to provide clearance for the screen’s adjusting knobs.

Nick, once again I will say it, YOU'RE A GENIUS! Your work is amazing and thanks a lot for this thread and any help you have given out over the years. I wish I could get my shit straight so I can get back to doing my fiberglass work. Thanks again man. Hopefully I can get back on the grind and get a new project. I just need to get my mind right.
Appreciate it. I hope you all got something from it all.
i c it as glassin and i c it as the wrong way to glass. i use the fiberglass cloth and shit not fabric.
but it's not....what's so hard to understand......you MUST have fiberglass to fiberglass something.period:haha:

it's like ''fiberglass resin''........there is no fiberglass in resin

it's polyester resin

u kno wat i mean tho

no...i don't really know what you mean?
lol ok noob to this but the best way to start is dive head first into it im starting on my center console and working my way to my shifter and then to my dash i figure if i do it that way i can f*** it up and fix it and get the tricks down then work on the more important stuff

my dash broke inside and i need to fix the part that holds the radio in.


i will be taking pics and i dont wanna hear it if im doing it wrong in your opnion. i am open to advice but dont bash on me like i said im new to this. but i got all day tommrrow off and all weekend to work on some small stuff to get the feel for it. will someone load the pics up for me ill just send them to you and someone else upload them to here like small? everytime i load them they are way to big.

im gonna have like 40 pics maby less but i want input will you guys tell me the best way to get the chicken wire to hold on the plastic befor i lay the mat i realy want this thing strong im gonna put my indash flip out back in and dont want it falling out

update i didnt add but maby 3-4 drops to about a measureing cup worth of resin and its taking foever to dry
also is this stuff bad for your health to breathe because i have to drive it to work later and dont wanna be stoned going to work.

pics will be up later tonight
no...the best way to start is not diving headfirst in......start small so you get a feel for it.....you already wasted a cup of resin because you don't know what you are doing......i might add that you are now going to strip it back off

if you had spent more time researching you might have read where me and nick both state that you need to start small or you will overwhelm yourself and get frustrated

and if you don't want to hear that you are doing it wrong then you might want to stop posting right now because i can tell right now you are going to hear that alot because you can't even read the mixing instructions on the can that states how many drops of hardner per oz. of resin are required

batch dried slow but still dryed i could have used a lil more hardner tho

also it was on only a few small parts nothing seen just inside of dash itself
it came out somewhat ok i do need more practice tho befor i even think about doing my doors
it was hard to get the pieces of broken plastic to hold with just glass alone next time im gonna hot glue then with maby just a dot or 2 to hold them while the glass sets up. becasue i didnt pull the dash it did make the truck smell like ass all day lol but for my first time i did good
also i got the batch a lil light on hardner but i didnt use a great deal of resn ether i forgot to mention i measured it like the can said i just went about 1 drop light
ok...you said a measuring cup which i automatically assumed it was 8 ounces

granted you should use 7-12 drops per ounce(depending on temp) then i thought you came up like 50+ drops shy.....

no i measured in spoons full i explaind what i did wrong. but ether way i was still off by about 5-10 your right. whats the average wait time for a normal batch befor you do a second coat tho? and 3rd? also is it ok to use like screen door metal screen for a more solid structer with the woven glass on both sides ? i was thinking for my dash the glass should hols if i get 4 layers down but i want it to support some 10 lbs max do you think the skreen would just be pointless?

also note i am a jackass sometimes when it comes to measuring converisons

i actualy only had about an ounce or ounce and a half but the reason i think i was off so much is because i used the big spoons in the cabnet not the small ones ether way it said 6 spoons of resn to 1/4 spoon of hardner and i think thats where i measured wrong.
i usually let mine cure over night that way i know its hardend properly. i could prolly do another coat sooner, but why rush?? rite toad??
overnight is too long without grinding, you lose the chemical bond

Yes and No. It depends on what method you're taking. If you are doing a wet layup where mutiple layers are going on one after the other without curing, then you have the added benefit of a chemical bond once all layers cure as one. However, if you allow it to cure more than a couple hours (depending on environmental temps and the # of drops of hardener added), then you'll loose the option for chemical bonding anyway which would require a quick scuff grinding before moving forward with the next layer. Its the state of the cure that depicts the type of bond.............which could be a result in minutes, or hours.

If the environment is cold or cooler, you are far more likely to achieve a chemical bond even if you're not a pro and working fast because the cure rate is dramtically slowed down. However, a wet layup achieving chemical bond is a more advanced technique requiring you to plan the layup and everything before even starting, or there is going to be a big headache, a f&*ked up piece of fiberglass and a lot of material resource wasted.

^^^ that's true but i never wait over night

if i'm doing a wet layup,i'll layup a few layers,as soon as it cools,i'll layup a few more....that's about the most i'll do,by then i am usually likely to have some defects i'll need to grind down to keep the subsequent layers smooth......

ok so for my second layer i just scuffed it up and put more on but im new to it so...
to get a stronger hold i need to just wait till the first layer sets then go for a second?
or is it ok to make sure its done and cured overnight?
DAMN I learn something from one of these two almost everyday...lol i have been knocking down the high spots after every coat. i will apply a coat b4 i leave 4 work at 330. then i will knock down the high spots or defects and lay on some more. when i get home around 2. so am i ok like this? i know nick said scuff it to create a bond. what will happen if i let it cure then add another layer with out scuffing? will it separate? not that i am gona try...lol just curious
i think it would hold, just not as strong of a bond, if i had to guess..

noob question alert..... whats "MDF" stand for?

MDF stands for Medium Density Fiberboard

Glassing is time consuming but if you do it right it looks like this

Thanks for whoring your pictures of what looks like simply overkill just to be cool smart guy and answer a question asked damn near a freak'n year ago. You now have all the cool points status. How many pairs of eyes do you have? I bet its hard to watch 50 tvs at once. Ever heard of "Less is more"? Nice job but save the show boating for another thread.

Wow someone is butthurt Because you could never pull off anything close to what i do every day. I know your pissed but it shows why. When you start a thread on how build custom panels you should first build something that actually looks nice instead of that piece of crap you call a dash.
