I know this is an old video but I would like to thank you for taking the time to create it. It helped me a lot to understand the differences and decide the way to go on my project. Thanks from Brazil.

[TIMBEAU]

Thank you so much my master for sharing the secrets of the material you use! Fabulous!

[strawdog]

great vid, plus it's always nice to hear someone in England buying stuff you can get in England. (as opposed to US vids that only buy from company's that only exist in the US)(never mind shipping prices for two pints)

[supranomicon]

Great tips and good advice, been casting for a while and use same techniques, agree with your comments on the differences between polyester and polyurethane

I just got into scratch building and kit bashing less than a week ago after binge-watching a few videos from Adam Savage's Tested channel, and in looking for more inspiration/education, I stumbled on this channel, and I have simply been amazed at the level of talent you display with your mech builds and sculptures that I've seen over the last few nights.


This video here, ready explains a lot for me, since I am looking to getting into modeling as well. I've only purchased putty modeling compounds, which is nice for small parts, buy resin casting is something I want to get into in the near future for larger shaped items, such as different parts of pre-made models, so that I'm not having to buy entire kits all the time.


So thanks for the video--it educated me a lot--and thanks for suggesting other companies that aren't Smooth-on, as I have looked into their products and was wondering about cheaper alternative.


Thanks. Look forward to you next video, as well as many of the others you already have that I still need to watch.


Awesome job.

Resins can cause sensitisations, you really should always wear nitrile gloves and a respirator mask or work in very well ventilated area. I’ve never used polyester resin but I like polyurethane and epoxy resin very much! Great video thank you 😊

for stirring sticks I use kitchen utensil handles, that are round, they work very well and are reusable, theyu are better for mixing silicones and resins, theres a knack in getting silicones out of the mixing cups but once mastered are really easy to use.
I use DWR too.

Great info thank you. i use large clear freezer bags for covering my scales:)

[alpaykasal]

Great info, great presentation of the info. thank you!

Good idea with the condiment bottle and cups, I'll have to look into those.
I can confirm jewelers scales work great for small casting quantities, I've used mine for a year or so and has made measuring my smaller casting quantities so much easier.


Do you use anything to try and prolong your silicone mold life? I used spray wax and talc powder, the talc powder is great for drawing in resin to areas that might trap air but doesn't prolong the mold life by much, but the spray wax helps with the mold life but doesn't seem to give a great finish (unless its the wax release I use?)


Cheers for uploading this, it was great to watch.

[FilamentForge]

just found your channel awesome content is polyurethane resin ok to use with latex moulds

[gazsto]

Brilliant video and very informative, would the Polyurethane be suitable for exterior pieces? I believe it has a very good tensile strength is that correct.

[NIGHTWATCHERUK]

First great to see a English video... question the polyurethane impact resin how strong is it ? the reason is I'am a bench Locksmith and some lock parts have to be replaced due to ware this would normally be expensive due to machining costs. If i can repair the part and cast it this would save time and extra cost to the

Hello sir are you know that how i make my plastic part from liquied to hard form please explain. Thank you have a nice day.

[tajiksofyat]

I have a problem with the polyester resin breaking when it falls on the ground. Is there a solution for that to avoid breaking it?

[smoll.miniatures]

Great vid! I’ve been using smooth on products and was about to purchase the crystal clear variant but saw polyester resins and thought I’d give them a research. Do you know any decently prices for water clear polyurethane resins? Can’t seem to find any at a reasonable price.

Sir I need guide line for pu hot casting for rod and sheet making. Please guide with us

[timothyjak]

Can resins be used to cast durable vehicle headlights?

[projectdalekmark]

Im going to pressure cast a 60's movie Dalek beaker in clear polyurethane. The beakers walls are approximately 2mm thick. Can you recomend a good value uk brand of water clear polyurethane?
