Hey Robert. So I have a project I'm working on, and would love to get your take on it. It's a simple static figure but the undercut makes it complex for molding. I think it might need a 3 part mold which I've never done. Is there a way to contact you to show you and get your feed back?
I’d love to see a video discussing the different Mold and Casting materials, and what use case makes one better than the other. Also, one thing that I’m personally currently learning is post processing. Would also love to hear how you smooth and finish your works. Grit levels, Primers, Filler Primers, there’s just so much! Haha
Nice to see you back! Resin casting is going to be my new hobby this year. I've got a starter kit (Smooth-On) and a couple of simple objects to get my feet wet. Thanks for the inspiration.
Thanks for such great videos. Watching your videos almost feels like being practicing right besides you. I really feel your channel is one great resource for DIY community on RUclips. I own a 3D printer and was looking up for ideas to build things. Watching your videos, I really liked the idea of epoxy casting, for epoxy is tougher, better performant against heat & moisture compared to PLA. Moreover one can avoid the layer lines & structural weaknesses along them. Additionally, like you suggested in one of your videos, its faster & easier to produce batches via gang molds. I decided to jump into it and bought epoxy resin sample to try. But then I then came along some videos that showed how dangerous epoxy resin can be, if safety equipment are not used. Respirator Masks, Safety Glasses, Gloves, Full body clothing ... This appears so much dangerous ( people reported being hospitalized and had narrow escapes ). Its even recommended to not touch epoxy until its fully cured ( ~24-36 hours ), this could result in allergy. Special care to be taken while sanding & post-production as well. That's some really scary stuff to me and trying that in a bedroom could be life-threatening. So, I never opened that epoxy resin sample I bought couple of months back. Infact, I decided to drop the idea of epoxy resin casting altogether. And may be look for alternatives to overcome the issues with 3D printing. After watching this video, I still feel fascinated by the idea of epoxy casting. It may also be that your videos makes it look easy. So, I request you to please share your experiences working with epoxy resins ( since you've been into it for 3 decades, that would be such valuable piece of information for everybody ). What kind of precautions do you follow ? And your advices for your viewers.
Hi Robert, love your videos. So informative and you're an interesting person to watch. I have a plastic gear to cast about 3 inches diameter by 1/4 inch thick which needs to be cast on its knurled metal shaft. I can't see anything like this in your videos, might be of interest to others as well. Cheers Marty from Perth, Western Australia
Hi Robert, great vid showing the fixture. I know how you love your beeswax but would Sargent non-hardening art clay work to do some minor repairs on a piece I want to make a mold of?
Hi. How are you? I am from Saudi Arabia. I am very impressed with your work and learning from it I made a two-part silicon template, but I had a problem. As the wax model dried out, it became very clear where to fill. When I tried to get rid of excess wax, the shape didn't look good.
Hi Robert! I wanted to ask if you had ever tried a short vacuuming of the loaded molds in the pressure pot before pressurising. I was getting bubbles on about 1 out of 10 parts from my molds, using a very thick polyurethane resin. Due to the part shape the sprues are thin, and seem to trap rising air bubbles via surface tension. Applying some vacuum to the pot seems to have pulled those few bubbles up the sprues now. There's less flash too - very nice result.
Hey Robert, I have a question! I want to make a silicon mold of a very complex object (a miniature church), and I believe it would be mighty prudent to use that pre-painting technique I've seen you use before. But I'm confused, do you pre-paint with silicone one day before the actual whole silicon pouring? Or do you paint it some of the more sensitive parts with silicon just before pouring the rest of all the silicon for the mould? If you pre-paint 1 day before and let it dry, wont the day-old silicone have trouble sometimes blending in with the fresh pour of silicon the next day? Thanks! Your videos are amazing!
Test that your mixed silicone will stick to itself after curing. If it does you can do multiple rubber pours over several days or even longer. Sometimes I pre-paint and pour immediately. Other times I let the pre-paint cure so that it doesn’t sag or run.
Hi Robert! Big fan of your videos. I've been trying to make moulds from resin-printed parts but the silicone doesn't cure properly. Do you have any advice for that? I use water washable resin and platinum silicone.
Platinum rubber is notorious for hating printing resin. You can try curing the prints under water. I recently did a video on this using Siraya Tech products. ruclips.net/video/nFbTO97CyTY/видео.html
hey, how about 3d printed outer shell cast molds, then pour clay ceramic (or plastic) in it, then burn the cast mold in ceramic oven, kinda lost pla casting but the pla is the container mold outer shell

Hey there Robert, I have a question in regards to silicone mold making. I’d like to make a mold of a xpf diorama wall piece I made with a window hole in it. What kind of silicone should I mold it with and what type of resin would be lightweight but rigid enough to make it durable. I’m guessing a two piece mold is needed to achieve the window hole without having to cut it out. Thank you for all the knowledge and experience you share.
Hard to say without seeing the project but I would be inclined to use a tin-based silicone rubber and urethane resin. You could ad a filler like microspheres to make the piece lighter.
@@RobertTolone it’s a 3/4 piece of xpf sculpted and painted with matte craft paint and sealed with mod podge then sprayed with satin polyurethane. Will it be necessary to use a release spray on the foam item before molding with silicone?
Hi Gabrielle, I’m only doing channel projects these days; it’s all I have time for. If you want to submit your mold for consideration send pics to roberttolone@yahoo.com.
I absolutely love your videos! As an inspiring toy maker/designer this channel has helped me so much! I have a question: Could you use an air compressor made for vehicles for a pressure pot? If not, is it possible to just use a vaccum chamber for both the mold and the epoxy resin?
Audio!! Perfect Robert. Thank you for the fix. You are awesome!
Damn the meniscus!!! Sweet fix though by shimming it up.
props to Daughters, I have 2 they drive me insane but I would do anything for them
There was bad audio in the first upload of this video; hopefully this is better!
sounds great

This is my number one channel about resin casting etc. So amazing!
You are a master!
Another great one, Bob!
Can't wait to make workshop drawers with custom handles now! Thanks for a simple and fun project!
I’m just so glad to see you back. I was concerned for you.
It’s been hectic; sometimes life gets in the way of my Youtubing fun. There are lots of videos in production! I’m fine, thanks for your concern.
Even with something as simple as drawer handles, I still learned a lot from this video. The jigs are really neat!

Resin printers are really incredible with the surface finish you get right off the machine
Thank you so much for sharing your knowledge!! Your videos helped me so much, not being dscouraged getting into this!
love your vids, got my first jugs of resin and some easy mold - your vids give me confidence
A new video! Happy Day! Subscribed to Patreon!
Aww ... your daughter is lovely, nice to meet her in the video.
Hey thanks Roger!
I only messed with a little resin casting a few years ago, but I love your videos because they are a learning experience every time.
Thank you for all the great content.
Very detailed. Seems like you could have also 3d printed that fixture.
A new co host. 👍
Sorry for the late post I started a new job and its seriously cutting into my youtube watching. 😿
That’s awesome
the router also does a great job of making an almighty mess!
Yes, I need to make a hood for dust collection.

Yes, I have done that in several of my videos.
Awesome! Can you do one on pewter casting?
There are videos casting in pot metal (similar to pewter) coming out soon.
C gets custom handles!

Can we buy tshirts that say “yank from the tank”?
How did you make a silicone mold from a resin print. Any time I’ve tried the part caused cure inhibition and the mold came out gooey and uncurled.
I use a tin-based silicone, not platinum based.
hey, how about 3d printed outer shell cast molds, then pour clay ceramic (or plastic) in it, then burn the cast mold in ceramic oven, kinda lost pla casting but the pla is the container mold outer shell
It would work if you wanted to make ceramic pulls.

@@APG2112 I don’t know but I would definitely test a sample of the rubber and polyurethane together to make sure it works.
@@RobertTolone thank you
I miss working with resin :c
Just a question, is a resin handle hard enough to not break? I remember my plastic ones being very breaky
hardness means its easier to break, I can break a hard steel thread tap in a heartbeat in soft aluminum
They should be tough enough for these light-duty drawers. If the drawers were full of heavy parts, you would want a stronger handle.
Come again?
I s'pose I'll have to watch again
Fixed the bad audio and re-uploaded the vid.
@@RobertTolone I hadn't noticed the issue the first time round, too happy to have you back really
Hi Robert! Would you consider making a silicone mold for me? I’m having trouble finding someone up for the job on etsy. Please let me know!
