I learned to do block molds elsewhere, but the extra tips (s-cut first, then straight cut) are super helpful! What I'd love to see you demonstrate would be miniature figurine (28mm) molding and casting, since that is what I mostly try to do. It sometimes works, but it's hard because the parts can be super small, and resin is quite viscous. Thanks, and welcome back!
Oh this is gorgeous. Loved the description of the vents!!! I still struggle making my cuts especially that “hairy” style cut towards the actual product, but this was a great explanation
The cost of silicone is so prohibitively expensive now, moulds like that are only possible if you're a large film studio with an almost infinite budget, it's way out of reach of the amateur model maker. I don't know about everyone else, but I can't afford to spend $500 on a mould for a single prop that would be lucky to only get one or two uses. You asked for suggestions in your last video, maybe you could cover some of the other far cheaper mould materials and techniques, like latex, gelatin, even RTV silicone (and non-submersion mould techniques)
This mold cost ~$120, working from a 16lb kit. All told, this mold probably cost ~$150 when you add in release, hot glue, clay, and foam core board. This could have been done as a brush-on mold, but it would have taken way more labor and the resulting part would not have been as "clean." This method is the most appropriate for the part, but if you wanted to save ~$50-$60 it could have been done with Polyurethane rubber. A polyurethane rubber mold, however, would require a stout release, complicating the paint work later. When you say RTV silicone, do you mean Tin Cure? Currently Tin Cure formulas are similar in price to Platinum chemistry. Both have their place, but RTV Platinum, like the TC-5130 used here, is much more accurate and ages better in storage. As for latex and gelatin, neither would work for this kind of mold. In future videos I will have discussions on methods and materials and the "why" of it all. The wrong method or material can wind up costing way more in time and money if you are not careful. Again, more about that in a future video! Thanks for the comment!
@@brickintheyard sorry, for RTV I meant the stuff you get in a tube from the hardware store, where I live it's called RTV or Caulk. Mix it with a little Naphtha (zippo lighter fluid ?) and work with it in a bowl of soapy water (dish soap ?) and it makes a perfectly good mold at a tiny fraction of the cost of Platinum cure. That's just an example of a cheap alternate mold material, there are dozens more. I appreciate seeing the different techniques you use but a lot of your examples are way out of the budget of most people. Like in this video, say it took you three attempts to get a good result, who can afford $360 for a prop knife ? Sorry, I'm not trying to be negative, but the price of materials is so high now that amateurs are completely priced out the market and looking for alternate solutions, and I thought it would be good if you covered some of them. Just a suggestion for future videos and to give you some content ideas, not a criticism !

Thanks for the input! Once I start up the 3D printing that will probably be a video.
@@brickintheyard That would be excellent, cheers!
yes shop tour!!!
Duly noted. Thank you!
Love it! Keep BITY ALIVE!
Thank you! The BITY spirit live in the interwebs!
Glad to see you making videos again! Thank you!
Thanks for watching!
Wow! Welcome back! I’m so glad you are back with your great tutorials. Best of luck!
Thank you! I have a lot of old video to edit and a lot of new ideas as well. The recent wave of 3D printing suggestions did not go unnoticed!
Hey! Wonderful to see you folks continuing on, on TH-cam.
Thanks! Looking forward to a regular video schedule!
Oh this is gorgeous. Loved the description of the vents!!! I still struggle making my cuts especially that “hairy” style cut towards the actual product, but this was a great explanation
Thanks! Cutting open molds is an underrated skill for sure.
Thank you!
Thanks for watching!
Great video as always, keep on molding Guys!!
Thank you!
Thank you!
Thanks for watching! My goal is to start a regular upload schedule.
Whoot whoot!!🎉
Woot (or Whoot) indeed!!

Have you considered a more affordable hobby? Perhaps bird-watching.
