There is a lot of time consuming work to make a mold for fiberglass parts. But the prep, the finishing of the mold is required, to get the finish you will desire, to get the replacement part to look like a factory replacement. This man is showing you exactly how it's done! I want to stress what he is revealing, the time you take to make the mold as perfect as possible, and the finish you obtain is what you are striving for! This man knows fiberglass!

[@tommo7146]

Out of all the videos on KZbin I find yours the the best, easy to follow you don’t miss any steps out and thorough descriptions of the products you use! Thank you 👍

[@davedmusic]

Love the channel! Thanks for taking the time to make these and share your personality and craft. It has been a bible for me!

[@mickfisch96]

Hi Andy. I’m new to your channel and love it. Thanks for sharing your years of experience. Much appreciated.

[@Twelvestonestacking]

Angly Dangly thingy.....funny .... funny! Things that are fun to say are WORTH repeating... as always truly informative techy stuff. Blessings, Scott

[@leesmith2200]

Nice approach. I built fiberglass fishing boats for 14 years and occasionally helped build both plugs and molds. While I am grateful to be in another occupation now, those were some pretty good years.

[@TryTryEh]

I swear... I love your videos! You are like the Bob Ross of fiberglass! I appreciate your work!

[@tylerw1418]

Haha that is accurate!

[@meneelyhouse]

😂👍🏻

[@FireCrowsWorkshop]

Dude, once again your tips save my butt and save me a lot of sanding! I might not work on boats, but currently building a plug for a miniature car (tot-rod). Sometimes I just get stuck with some things, but yet again, watching your video solved one of my problems! Thank you!

[@randalllay806]

Thanks Andy!! Keep the videos coming, really appreciate all the info.

[@Cynic58]

Andy, thanks for all the informative videos. With your help, I will soon start my small fishing boat build with confidence!

[@jamesford8315]

Thanks for yet another great video. Will be performing your magic this spring for port and starboard cockpit lockers, no originals.

[@IslanderSailboatInfo]

Been the best for years Andy, still the best, well maybe sharing it with that guy from Tips from a Shipwright 🙂

[@xXBocephusXx]

Great video Andy! Very informative and interesting. Also, I love that tip of scoring csm before tearing! Thanks

[@geoffstein3896]

Great video mate, your tips help out so much.... With how much work my boat needs I wish I was your neighbour 😁

[@FritsvanDoorn]

Useful video. Thank you. By the way, I saw your video from 2 years ago too, 2 years ago, and that is a good one too !

[@geoffstein3896]

The best Andy 👍

[@Rodneydncn]

I learn so much from you! Thank you so much for the video, see you on Patrion

[@woodratworkshop5968]

Nice one Andy, that's really useful.

[@mvbigblue7863]

Great video! Been wondering how you make a mold from scratch!

[@SailingYachtZora]

Thanks Andy, exactly what i was looking for! Love your work. Rhys

[@SailingInconceivable]

Excellent, Andy! We have a future project for Inconceivable - a mid cabin skylight to hatch conversion - which may incorporate some, if not all, of your tips from this vid. Thank you, thank you! ~Hans

[@MadPropsMakes]

Nice! This is great info... I plan on making a hatch cover for my bayliner I'm restoring over on my channel and this is what the dr. Ordered

[@blueskypoa]

Thanks for sharing. It helps me a lot

[@UweBehrendt]

Thanks Andy

[@THECARKUS]

Thanks Andy.

[@miguelatambucho748]

Master master 👍🏼

[@doesntmatter3068]

This guy good, but I wouldn't go as far as calling him a "Master"

[@Joethebaitguy]

Great video I’m new to boat building and this really helped

[@jasonmcintosh2632]

Awesome video. Those molds are a lot of work!

[@2Langdon]

Very good how to demo, thanks.

[@allensooter8429]

Great job Andy, I needed to see that, I have hatch door on the Cruise A Home that is on the fly bridge to make. The good one I have is a raised panel design. It is going to be a problem to duplacate.

[@justinmobrien91]

Really informative and well presented

[@Captaingps65]

I have to say You are Good at what you do! I have seen a lot of your work s and you must be just as good at editing ! Haha It’s nice to watch a video and Actually learn something that you can use on your own boat. Thanks again.

[@nathanoppermann8896]

thank you

[@eriksvsirocco]

Thank you!

[@fintryendrickwildlife1619]

thoroughly enjoyed … from Allan in Scotland

[@keithmorrison8199]

I work for a performance boat manufacturer out of Michigan but have been wanting to do more side work with composites, the tip on lightly cutting ounce and a half matting for thinner strips is genius and I’m kicking myself in the rear for not thinking of that, great video

[@stevenclist6644]

All I can say is a big thank you, without your knowledge my boat would still be in the waiting to be done , especially the stern repairs .

[@tomharrell1954]

This is the man to teach you!!!

[@curtisprincemusic]

Super awesome Andy!! Really appreciate this vid! I was one of your subscribers that asked about a “mold making vid”, so thanks much! Strongly considering building our own hard dodger for our Crealock 37. I’ve been a woodworker for 30 yrs so the wood part is easy, but I really needed the instructions for all the other steps. Feeling much more confident after this vid. Thanks again Andy! Peace

[@tomharrell1954]

Go Andy!

[@TrailToughTrailers]

Andy... great videos!!! Every time I watch one I itch all over. I hate the idea of fiberglassing anything, which bring me to a couple of questions. Do you ever do things outside the boat industry like RV parts and do you train others for money? Thanks for all your videos and your attitude towards doing things... I love the easy going approach! Hersh

[@dawsoncreekinthephilippines]

Nice thanks another great video

[@exploreseafaring]

Great to see another video! In college we got taught you need to allow the fumes to escape a mold while it cures. They will gather in the base of the mold as they are denser than air. Is that something that only relates to deeper molds or is that not really going to make much difference to the overall end cure?

[@goosecoveboatbuild5466]

Great video. Very informative. A quick question. Do you ever have a problem with PVA beading up on wax-containing gelcoat?

[@jaywinters2483]

I LOVE this vidie

[@TableRockDiverDougB]

I used your earlier vids to make a copy of my tread pattern for my 88 Cruisers Inc. Worked awesome. Even my mechanic couldn't tell it wasn't factory. Thanks for this video. I enjoy watching your different projects

[@mikeoconner1356]

Thank you Andy!

[@jimdunkerton7344]

man thanks, unfortunately a little late for me, 2 years ago i had to make a hatch for my north American 23. i used the original part, it didn't release...well. its basically 3 triangle shapes that make the hatch, nothing flat and nothing 90 deg. its quite a challenge. it didn't come out well but will work till i have time to do it right now that i see how to make a proper mold.

[@curacao11]

another awesome video

[@frankenstein3163]

ty 4 vid

[@ipipunic]

Great videos Andy keep it this way. One question about this mold makeing. Why you didn't use origanal part to make mold applying over it PVA or wax and the gelcoat + fiberglas to make mold?

[@seriksson9721]

Thank's

[@mhansl]

Me 2 years ago: Ok. Fiberglass mold. Me now, after our boat got damaged: WHERE'S THAT VID ANDY MADE ABOUT HATCH MOLDS!?!?!?!?!? Thank you for your channel, Andy. It's been sort of a dip in subscription until now, when we really need it. Repairs, refinishing, remodels.... Your channel just became a serious go to for us.

[@jimmycrites1647]

Can you use sign board for mold

[@jimmycrites1647]

Making a conoe

[@moonman774]

Just found your videos! Love em. How many paint brushes and plastic cups do you go through a week!?

[@YooTooobJeff]

We always sprayed PVA in the mold first, let it set, then sprayed gelcoat, then did the fiberglas buildup to thickness desired... Pops out finished!

[@tigo1236]

I have watched you fill holes while the srface was flat using glass and PE resins...if hole is vertical, do you use filler compound don't doesn't run and if so to what descriptive thickness? Thanks for your amazing videos!!!! Love them!!

[@GalvestonGuy]

Cool!

[@elvism2000]

Hey Andy You make some great videos I want to ask you can you use adtech p-14 on the hull under water line ?

[@dgourdine50]

Great Video as always !!

[@gary5831]

You dont use any kind of mold release agent? Very nice video thanks for your time.

[@dormanski4170]

Thanks great video I could have used that 6 months ago. My next project is a hard dodger. 3 ideas. Are typical glass over plywood make foam core and glass or waxed the core and glass and pop out the core ... any ideas would be great. Plan to start soon

[@ianluscombe7429]

Really enjoy your programmes, how would you deal with the mould if a non slip finish was needed.

[@user-or2xg6ji4e]

Great

[@loganjack214]

Hello Andy, thank you and a quick question- Is there a problem with omitting the glass in the mold? Just gelcoat, sand, putty as required, sand, and then wax / spray with PVA?

[@amcrome]

I'm such a rooky -I thought the wood was the mold and was waiting for you to pop the part out and finish the top - doh!

[@eshootziscrs2868]

Same thing in a way. He will end up repeating the process with a little variation. So really you are right, just ahead of your time.

[@patrickkeyser2762]

I love your videos! I was wondering why you didn't use the existing hatch as a master by coating it in wax and pulling your mold right off of it?

[@Ja518]

Hi Andy, do you have any videos on repairing random holes? Will be removing an old fiberglass twin engine bracket on my boat and want to patch the holes up so I can mount the new bracket in a sturdy transom. Cheers!

[@houseoffire72]

Hello Andy. I have been subbed to your channel for awhile now & watched most of your vids. Im very interested in boats. Mainly small wooden and or fiberglass. I have about 25yrs of frp under my belt blah blah blah lol😀 I have two quick questions... May I ask why you did not use a tooling gel coat for your mold? And since I vist Saxon Harbor a couple times a year (2hr drive) would it be possible to stop by get a tour & learn a few things from you? Shawn

[@biltre21]

Great video, thanks. Since you have the original part anyway, couldn't you make a mold directly from it, wrapping the fiberglass around it?

[@gatordave6629]

Love your videos I'm young and new to boats was wondering if I can send you some pictures and ask a few questions sometimes

[@Sr27class10]

Hi , love your vids , I'm converting a mini bus to a camper , I have a 5m x 1m area to fill and was toying with glassing it , do you think I should use polly or expoxy for a strong side panel ?

[@luke0b708]

Is that finishing gelcoat sometimes called flowcoat? Thanks for the great vids!

[@plamenpetkov400]

Hi, great video and great channel. You’ve just got a new subscriber! Quick question: I am building a t top for my boat and planning to build fiberglass hardtop 4’x 57”, do you think I can make it with fiberglass only, using mild or it’s better to use 1/2” plywood for base and than 1 layer of polyester resin and 2oz mat? Thanks Cheers

[@SunmiOfficial]

감사합니다~

[@quiquecars]

Hello all, im new on the Fiber glass build parts, this time i have to make a complete falt surface about 6mm thik, my question is, should i take a regular glass as a mold, Apply wax or pva? The thickness I would have to make all out fiberglass or some in between. Thanks for help.

[@jeffreyacoleman1413]

Sweet project I used aluminum foil on a kayak seat Super cheap and can from to any project

[@quefaitloulou2334]

How simplifying something to make it idiot proof ...you are just amazing ..very good video as always ...

[@gulfwaterfishing8731]

Hey Andy, love the channel. I have done quite a bit of glass work in the past and im on a new project maybe you could lend some input on. I just bought a new fishing boat and I am going to build a 30 or 40 gallon (roughly) oval shaped stand alone livewell like you see on a lot of Florida west coast center console fishing boats. My question is this. I will be building a one off mold to pull the part off of and I know there are a handful of different materials I could use to accomplish this. My first thought was to build a 2x4 rectangle form and lay a piece of 1/4" finished panel inside to make the oval shape and use a piece of melamine on the bottom and top, lay my filets in where they need to go and shoot it with 4-5 coats of pva and then gelcote and glass with maybe a very light core in the main body area. Do you have a better idea or a better way to accomplish this, and by better of coarse i mean easier haha, thanks I can send you pic of what I am going for if will help

[@Hyperstasiss]

Could you use this same method to make the molded recessed gunnel rod holders but, would have to make tabs on the outter edge to attach to boat

[@jeremydionvideos4274]

Hi Andy! Big fan, I currently have 2 makos I'm working on a 1972 22' and a 1978 20' I'm almost done the 20 but need some advise on the 22 the old cabinets and wells in the stern area are gone so I need to build more. I was hoping you could give some advise on the best way to go about it .. Thanx, Jeremy from Chicopee Ma!

[@josetorres.8845]

Wow that looks like a lot of work for s small piece of fiberglass

[@devodave71]

I love your video's , but I do have a question for ya , I bought a 1978 Glass master tri-hul , some one had hit something and the damage is on the outer Tri -hul and I can not get to the back side and the cracking from the Damage runs pretty far back , I have pics but damage is damage but was wondering If I could mold a piece of dense styro foam as a backer to stuff in the hole to lay down my first layer of glass? have you tried this before? and will it take the heat as the resin tacks up

[@MrDiogoSilveira]

Hi there. I have watched your videos and let me congrats you for your experience and for your projects. I have finished my center console, but when I got the concole out of the mold some of the gelcoat doesn't cure and is wet. What can I do now? Thanks.

[@derrickwalter5739]

Im building a wooden boat. Could you do a video on which resin is better epoxy or polyester? I am having a hard time deciding which one i should use. It is for a custom wooden boat made from standard 2x4s and plywood. Thanks in advance!
