At the rate things are going...in a 100 years( probably less) people will be able to 3D print car parts in their garage. Nice attention to detail, thanks for sharing your knowledge.

[@acurafillfilip9868]

Came here to upgrade my fiberglass skills but you got me hooked on the Volvo build. I used to build surfboards and repair fiberglass sailboats and thought I had it tough but I now realize that plug making is a wholly different ball-game. No room for errors! Back to KZbin school for me - thankfully there’s excellent people like yourself out there who are willing to share their knowledge! Love your approach and regular servings of (Irish?) humour!

[@ThrottleStopGarage]

Thanks for the kind words. I always try to be as thorough as possible to help others that are trying to learn. My family is of Irish origin, so the humour has stuck. I mean if you can't laugh in a project like this it will win.

Whew! For a second there I thought you were sanding the fiberglass without your respirator! About 30 years ago I worked with fiberglass to make trim templates. This was before multi-axis lasers were affordable/common. We used the templates to trace a trim outline for prototype sheet metal parts. I also worked for a company where we made replacement helicopter windows for the UH-1 Huey. Fiberglass frame around a plexiglass thermo-formed window. Good times! Great video!

[@Winha277]

Great video! What I would do differently, I wouldn't laminate those wooden stiffeners on the mold. They are likely to imprint through the mold surface after some time. I always use some flexible glue, such as Sikaflex, to mount the stiffeners on molds if possible.

[@ThrottleStopGarage]

Thank you for the positive comments! Much appreciated.

[@bryanst.martin7134]

Nice work! Only suggestion I would offer is to cut your reinforcing components to eliminate springing of the wood. Or back fill them with Bondo. The large glass areas shrink and pull the components together and can cause flattening of your compound curved hood. I like to use rollers to spread the resin quickly. 3", 4", even 9" rollers for large deck areas. You can pour the resin out in zones and quickly disperse the resin before it cooks off in the pot. Of course I deal with higher temps on the average. Ol' sunny Florida. Gotta think quick to stay under 10% waste.

[@ThrottleStopGarage]

In my next episode, I tried what you've suggested - worked like a charm!

[@paullatour7012]

Fantastic video. In a previouse life I worked at a fiberglass production shop and I loved hanging out with the mold makers. I didn't see anything you did that I would do differently being that this is not going to be a production mold. I have a similar project coming up and I hope mine goes as smooth. I can only hope that I get a release from the buck as perfect as yours did. Belive me I have seen it go really bad sometimes!

[@ThrottleStopGarage]

Thanks Paul...when I made the hood mold it was a full day before I got it out! Time spent getting the mold perfect is so important. Video's make it look easy - it isn't.

[@onepairofhands]

hi again - not long done a boot for a car i am building....same method as you, and the elation when the mould releases the part is something you have to experience to know how good that feels ! your wood idea is a good one, not only will it stiffen up the mould as you state, but if your garage space is limited as is mine, you can pop a couple of hooks in and hang it up and out the way !!

[@robertcoles4709]

Great video. I use flexible hose to create Omega stiffeners instead of wood. It allows me to make long stringers without too much work. But your metal frame is the best.

[@ThrottleStopGarage]

Thanks Robert. I'll be trying some new materials on the next molds.

[@johndevries8759]

The wood stiffeners will imprint thru the mold. It's better to use a filler such as an expanding foam. Put a layer of expanding foam about 1 1/2 inches thick down on top of your last coat of fiberglass. This stiffens the whole mold and doesn't show thru. It's light and very strong to support the mold. I learned this from a professional mold maker. You can buy the foam as a two part agent, mix it up and just pour it on top of the mold and let it set up. A little cardboard around the edges keeps it from falling off before it sets up.

[@ThrottleStopGarage]

I didn't know about this at the time. On my last mold, I attached a metal frame with some short-strand body filler...worked great.

[@InsidiousDr9]

The reproduction should have more bracing where the original bent from people slamming. I hope you put good notes on these molds, what they're for, the original make /model of the masters - that way if they turn up in barn somewhere in 80 years from now someone still may be able to do a historical restoration. Great stuff.

[@leftcoast9261]

When we used PVA, we always just used a rag dampened with it. Only give it one wipe. Always worked and gives a much better glossy surface. We never put it on so thick that you could see it.

[@ThrottleStopGarage]

Thanks for the tip...I'd just been told to hit it with lot of PVA - which is a total PITA.

[@leftcoast9261]

@@ThrottleStopGarage Yeah, we found a LOT of stuff we were told, didn't hold up to actual testing. We ended up running tests on everything that came in the shop, just to see if it really worked or was what the salesman said it was. I picked up the PVA trick from a guy that spends his life doing double sided infusion parts. He'd take a rag soaked in it, wring it out and just do a quick wipe. The parts came out looking wonderful.

[@iambeeman1]

Modeling clay: you want low sulfur. I'm not sure what the differences are out there but we always keep the low sulfur stuff stuff around for this exact purpose. Release wax: we use 5 coats, but more is always better than less. It's a special wax that tolerates the heat of the curing process. Also, it's a sacrificial layer that is destroyed with the removal of the mold from the plug and must be reapplied if you are making more molds from the same plug....assuming the plug survives. A good plug should get you 5 molds made from the same plug. A bad plug may need to be chiseled out of the 1st mold. I say a great plug go straight into production and serve as the mold for a minimum of 600 parts with no sign of any issue other than normal wear and tear. PVA, we never use it like this, we find the finish is too poor for our purposes. It is a sacrificial layer that ensures a very good release, but must be cleaned off and reapplied every time. Gel coat, we never brush unless it can't be avoided. It increases the likelihood of pinholes and porosity. That said, there are different systems out there that mitigate that problem and you should always refer to the instructions with your system. We spray and those of us doing it prefer to thin it by about 10%with acetone, but that is off label and management doesn't want us to...they sign the cheques so we don't thin as a rule. Glass application, you definitely want to begin with a high tack gel cure stage, it ensures a chemical adhesion which is better than a mechanical adhesion. But we prefer to apply the resin to the gel directly as its easier to chase the bubbles up with the resin than force the resin down through the air filled glass. The first layer of glass should be a resin rich layer, the woven cloth is an excellent choice, a vale works well too. The subsequent layers should be the chop strand mat as its the most cost effective option. But the overlapping edges should be torn not cut, because the overlap can create a resin rich line that can shrink more and create a line in the mold that will need to be dealt with later in the part. After the first 4 layers of 1.5 oz are cured we put in 4 more layers but the tearing is then unnecessary as it can't pattern through anymore. We use the optiplus II system from polynt (pretty sure its not available to.the general public though, we are an industrial manufacturer) and get only about 45 minutes of work time out of it, so we work fast. Wood gusseting/reinforcement, we use wood extensively but plywood, and we will slit it almost all the way through when applying it as you've done on this mold so that it can conform more closely to the surface. But be aware that the wood placement can pattern through to the surface of the mold. Demolding, air pressure from a blow gun is a perfect tool most times. Finishing mold surface, if you can avoid sanding the mold it is best. Sanding the mold opens pours that can build up with styrene over time. Not an issue with limited runs but something to consider with production molds. All this said, this is not to be in the slightest bit critical of you or your mold, it looks amazing and you've done a great job. I'm simply relaying what we've found over the years, and I was trained by a guy with 35+ years making production molds. Loving you videos, keep it up.

[@ThrottleStopGarage]

[@peterburgess7314]

[@ThrottleStopGarage]

I can only imagine!

[@michaelvadney5803]

Really good video. I've also found that pulling CF parts from these molds are a lot easier than pulling fiberglass parts. Less chemical smell too. I was always worried about alligator marks in the gel coat and having to lay the fiberglass down on the gel coat after it started kicking. It looks like you did not have this problem even with you let the gel coat kick completely. I know that it stays tacky, but I did not know that you could take your time between the gel coat layer and the fiberglass support layers. Thanks!

good work, I like to use air/blow gun to pop it off, some real stubern ones you can use a water hose. parts like yours are almost eazy to pop off.

[@neuxstone]

Hi. Good work on the mold however. The only thing I see you consistently do is omitting using Cabosil. Silica gel made from resin and fumed silica until you have a gel the consistency of vasoline. Use it to fillet around the edges or anywhere your material can’t adhere to the small details of a part. Keeps from getting air bubble gaps that later turn into craters in your molds. Other than that MOLD ON BROTHER!!!

[@ThrottleStopGarage]

I didn't know this existed. Where do I get it?

[@neuxstone]

I believe West Marine sells it in small quantity but you mix it 150% to 100% resin and you’ll find yourself using it all the time. I buy it in 20lb bags which because it’s light is a pretty big bag by volume. If you don’t have a West Marine near you can order it online. It goes by the generic name “fumed silica” or product name “Cabosil”. It will make life a lot easier and your molds won’t deteriorate around the corners where it meets the flange.

[@ThrottleStopGarage]

@@neuxstone Thanks - going to try this on the next round of molds!

[@fillman86]

[@ericstafford5522]

Never use cloth it inprints badly. I always pre-wet my mold before laying on chop strand. Bondo your wood down then layup. All my molds have couple holes drilled in the middle to blow air in without using wedges.Just my two cent's. I like what your doing looks good.

You don't need such thick layer of PVA. Just put a fey light coats to avoid runs. If you really concern about PVA thickness add a few more light coats. But don't spray it such thick in one pass, otherwise it will form runs and heavy orange peel texture.

[@ThrottleStopGarage]

I figured it out eventually.

[@volvovalor8051]

Your friend is going to be happy though when he sees his trunk back.. :p

[@ThrottleStopGarage]

He was.

[@ralphthedog1680]

Why didn't you make the return flanges before you pulled the trunk lid? It was perfectly set up for return flanges to pick up all that detail and support on the inside. And with those nice wide flanges you made there was plenty of room for dowels to locate and bolts to fasten them. If you make you mold from epoxy you will have more time between the layers of fiberglass and will be able to smooth everything out and wont have to grind between layers, never seen that before, even with poly.

[@ThrottleStopGarage]

The frame would have locked in place because of some of the return angles. So I decided to give the nice hood back and use the trunk I had. I cut it all up and made two molds to make the part. It all worked out just fine.

[@ralphthedog1680]

@@ThrottleStopGarage The return flanges would have been loose and would have came off first.You could have made them in 2, 3 or as many pieces as needed. It turned out just fine but could have been so much sweeter and closer to original with just a little more work.

[@TheZahnputz]

why cant you use the loose fibers for the first layer? i thought the polyester resin dissolves the styrene binder in the mats

[@ThrottleStopGarage]

I had no access to loose fibers. The polyester does soften...but when you're working quickly you do silly things like cut CSM instead of tearing it.

[@TheZahnputz]

@@ThrottleStopGarage i meant the fibers in the csm, that become "loose" after coming in contact with the solvents. is it more difficult to fit those to the shape when putting them directly/dry on sticky gelcoat?

[@ThrottleStopGarage]

Yes, they're stiff until the resin dissolves the binder. So while some guys I've seen just plunk the CSM down and go at it, I've not had very good success with that method. I now use a surfacing veil which is great, but if you can't find it or don't want to pay for shipping (a real factor in Canada) then a little cloth conforms and works well.

I've heard cooking spray works good

[@ThrottleStopGarage]

In the video, I used release wax and PVA - it worked fine - though I've now learned a few good tricks for PVA from viewers. You can dry it easily with a heat gun and you don't have to put on so much. I only use products that are designed for the task. Mold release wax is different from car wax for example. You could also use a chemical release agent instead of the wax. Just follow the instructions exactly.

Why didn’t you polish the body filler? I think I’d chose To go all primer or all polished paint what’s the point in having a partial buffed surface for a mold you lost me in the first 3 min with that pointless crap.
