Anyone in the Cleveland area up for a paid consulting gig?
We are looking for a good machinist/moldmaker for a quick gig for fair pay. Specifically looking for a technical consult for hand fitting a complex geometry injection mold that was already cut by CNC.
Probably will be VERY minor actual work involved, more of a “yep, you do this and grind this surface and blue this surface here and compensate here and you are doing it right why the hell did you pay me to tell you this?”
Put in a weird position due to an employee with the lions share of technical knowledge exiting the company in the middle of a job and just need a quick double check/tutor for a day or 3 worth of work.
We will outline the job and let you know what’s going on and you offer us a quote for your time at our site. If it’s not unreasonable and you have the experience and know how to do it it’ll likely be a done deal. Happy to talk about future paid consulting gigs like this in the future or other opportunities to fill the gap afterward.
Also looking for an injection mold designer that can take our Designed for Manufacture models and create injection mold designs based off of existing molds. (Same base, same general idea, different part geometry) - this we are looking for either in house hiring or farming it out to you.
Feel free to message me and we can get into the details. Thanks for your time!

Please visit my blog to get an idea of some projects that I have been working on. I specialize in urethane and silicon rubber, urethane plastics, cement and plaster products. I am used to working both large and small scale.
Experienced moldmaker. I am familiar with urethane rubber and resin as well as silicon rubber. I can make molds to reproduce art, architectural elements, or almost anything you need in a variety of material including plaster, plastic and cement.
I am a moldmaker/sculptor/artist looking for freelance, part time or fulltime work. I work with urethanes, both rubbers and plastics. Silicone rubber and a variety of gypsem and cements.
Current work can be seen on my blog:

I'm looking for someone that can teach me basic mold-making for prosthetics; I have some background with clay sculpting, but no experience casting things.
In return, I offer drawing, painting, color theory, sewing, basic Web design, theatre, or Photoshop lessons, or related services. I provide my tools/resources, you provide yours. Each person buys their own consumable materials. :)
(strange post maybe, but I thought it couldn't hurt to try; feel free to pass this post along to whoever might be able to help! thanks!!)
So a local plastic part manufacturer approached us to make a replacement core/cavity of a four cavity injection mold.
Relatively simple job, took us only 2 weeks to complete, well within the customers deadline. But now the same company would like an entire replacement sets of some of their tooling. My boss is not sure on how to proceed with this job as we are mostly a maintenance and machine shop for the aerospace and oil/gas industries.
Are we supposed to make the entire mold? A friend of mine works for one of the best tool and die plants in the country and swears that all the molds are standardized and that all they make/design is the ejection mechanism and core/cavity.
I thought there would be a lot more to it than that.
I could do with some guidance on how we should tackle this job if we accept it.
Hello awesome machinists,
Disclaimer: I am a self taught hobbyist, I have little experience in CNC milling, and I am looking to improve my skills. (the last part I made is the following mold https://imgur.com/a/iiqesP3)
I wanted to machine an aluminium mold to make my own switch plates like these ones:https://images.homedepot-static.com/productImages/696f1006-b16c-4f0c-a453-2a95bd7d7bcb/svn/white-leviton-toggle-light-switch-plates-r52-00pj1-00w-64_1000.jpg
for the curved wall, I was going to use a ball endmill, However, how can I get this sharp(ish) corner at the same time?Is there a specific type of endmill for this or should I go with a rough pass/large endmill for the straight walls and finish the 90 degrees angles with a very small ball endmill?
Sorry if this is an obvious one.
Thanks a lot!
EDIT: to clarify, I am looking for a way to create the negative of the reference photo ( especially the corners)
I am trying to make platinum silicone molds of some pieces I have printed on an Elegoo Saturn. I have been filling, sanding, and priming repeatedly and am very close to the mold making step. I know resin 3D prints inhibit the curing of platinum silicones and so do some paints. Has anyone had any experience using this rustoleum automotive primer and making molds of an object coated in it? Will it cure correctly? I will be using Smooth-On's Mold Star 16.
I know I can of course do a small test on the objects but I am waiting for the silicone to arrive in the mail which might take a week. Was hoping I could get ahead and already start setting up the mold boxes, filling in the half with clay, and create the parting lines.

I hope I'm not braking any rules or offending someone...I'm gonna be straight about this, cause there's no other way to say it: I'd like to make a dildo, a silicone copy of my own penis. It'd be a great gift, but I don't know much about silicone and I need some help.
Is there any moldmaking silicone that can partly cure in a few minutes? Less than 10 minutes preferably?
PS: Please don't recommend the Clone-a-Willy kit, the results are horrible. I'd prefer if I bought the silicone and parts myself instead of getting a pre-made kit that was designed to save on costs.
I'm going to be making my first silicone mold today or tomorrow.
It's going to be a two part mold. I forget is there something that is supposed to go between the two halves so they don't stick. I know one side is cured and then you pour more silicone on after.
I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.
Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
Hi!
I like to work on a scale of 1/4-1/3 life for full figures, or up to lifesize for just a portrait bust.
I've been seeing lots of really awesome stuff on this forum done in monster clay, which looks like it takes smooth finishes and high detail very very well.
My concern is, how hard is it? to build up something larger?
do you soften it in a crock pot and then mold it up? can you cut it with a hot wire cutter?
or maybe, I can do my rough in clay, take a mold, then pour in the monster clay to make up the finished and refined piece?
My second question is this: if I DO make an interim mold to pour monster clay into, what would you use to make that mold? I'd prefer not to spend $150 on silicone rubber for a single-use mold although that might just be the cost of business. I could maybe do a plaster waste mold + monster clay. Even plaster is $1/lb where I live though, which kindof sucks.
same question applies for the final mold: i'm interested in making a wax to cast into bronze, but just a one-off not a series, so it doesn't need to be a mold that's good for dozens of pours. but it does have to work well the once...
thanks for the advice!!

Do your worst!
I'm surprised it hasn't decade.
For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies 😂
It really does, I swear!
Hey everybody moldmaker apprentice here. I’m in my in my last 3 months of my 4 year apprenticeship. When I first started in my shop there was zero structure for the program and stuck it out for about a year and half until shit really started to move. Since the beginning I was kind of left alone to figure things out. I would ask questions to people in the same department and try to YouTube or google similar problems. In the time since I started I went from not knowing how to even hold a micrometer to holding +0 -.0002 regularly. I’ve learned how manual mill/lathe, program and run cnc mill/lathe, surface grind, form grind, mold assembly, wire edm, polish (minimal experience) and I’ll be heading to edm sinker soon. I’m super great full for the opportunity to learn and grow but during my last review right before I’m supposed to be offered a full time position things changed. I was getting stellar reviews before and never heard anything wrong about my work before hand, but now I’m hearing that I’m unreliable and they don’t know if they have room for me. They said maybe If I do another year at my current pay and if I improve my work ethic I can stay. Im only making 1.50 over minimum wage. I’m 100% getting my certificate in 3 months but potentially jobless. Honestly the entire experience has made me feel as if I waisted my time and made me pretty depressed. I take pride in my work and even as an apprentice I rarely ever scrapped out parts. Sorry for the long read, what would you do?
Because she wanted to see the task manager.
Heard they've been doing some shady business.
