As I am watching this I am 3D printing a custom gearbox mount for my Volt. I am using TPU 95A with 40% hexagon infill and 5 shells plus 5 bottom and top layers. I just did a web search and it seems that TPU 95A may have not been available at the time of this video. It is amazing how 3D printing has revolutionized the DIY engineering scene. Great video!
You normally dont need to destroy the moulds, just squirt some compressed air down the sides and the rubber part will pop out. If it is hard to get down the side drill a tiny pinhole in the bottom and squirt the air in the pinhole, then the pinhole can be covered witn sticky tape for the next mould use.
Another good variable to check is how much the engine moves when you load the drivetrain. Pop the hood, start the car and put it in drive (in an automatic), but hold the brake with one foot, and give it some throttle (so the car doesn't move!). Note how much the engine rotates as it revs.
You can use PVA (which is a water soluble support filament) to print the molds. After casting you can dissolve the mold away from the casting with water.
I need to do this for four 12in wheels in a 5 piece printed mold that I made to cast around aluminum pit bike wheels. PU looks thick and gloppy. Air bubbles are gonna be a big issue. Ugh :( Wish me luck.
I know this is an older video but the poly set up like that because of the 170 degree temp. I'm surprised the can even suggest to get it that hot. The hotter you heat it up, the faster it sets up. I would went with about 150. Also, if you have an air compressor, those will pop right out the mold with a little air blast.
It's my first time working with the stuff, so I was just following the instructions as close as possible. You're the second person to recommend using an air compressor, which I do have. If I have to make more in the future, I'll remember that.
Hey great vid do you have somewhere we can talk business I’m looking too pay you for fabricating mounts for my car if something your interested in please let me know
I’m waiting for that original filled motor mount video and results. I don’t know if you are up to making it a business but I would buy a new one done from you. If any other viewer are up to buying them please reply to this post so we motivate him selling them to us.
I just need to edit it together and then actually swap in the mount to test it, but I've been busy this week. I promise I'll have it up soon. As for selling them, the only issues are that I would need to test it to make sure there are no issues and I would need a mount to fill. Also, you need to use the entire contents of the can of urethane to have the proper mixing ratio, so that would be a huge waste for one mount only.
Derrick Aquino I can ask my crew and we can make a list here on RU-vid if anyone is up to. We send you the money in advance. Lest wait for the video and then we can make work around the how to.
Sir would you tell how long casting should inside microwave and temperature in celcius/farenheit. I'm quite difficult to understand your explanation my listening English not so good. Thanks 🙏
They don't sag and they prevent the exhaust from bouncing around. They're great if you need the exhaust to sit in one spot to avoid hitting the bumper or anything else. If I didn't have them installed, my muffler would bang on my trailer hitch all the time.
I haven't used TPU yet, but someone commented in one of my Facebook posts and said they "printed many parts out of 90A TPU and they seem to hold up well on both race cars and street cars. I'm sure the molded product is better though."
I currently supply a customer with poly bushes 3d printed in ultimaker tpu, he uses them to build up the custom air shocks on his air ride systems, they work really well.
I think a filament printer is better for something like this. I'm not sure how well resin would hold up to being baked and how hard it would be to pull off the polyurethane.
Hey dude I really appreciated your video. I subscribed and all. Where did you get the bushing sleeves and would you be able to help me with gathering the measurements for my bmw e46?
Do you mean the sleeve bearing that sits inside the bushing? That came with my aftermarket mount. As for measurements, I recommend getting a digital caliper. I used one from Harbor Freight.
I got this a while ago and can't find the receipt in my email, but if you follow the link in the video description it shows at $33.99 plus shipping. It makes 13.52 fl oz. Follow the link for more info.
Hello, Derick Can you make me 4 bushing for the from EMU lift kit, they send me the wrong size. I need 4, - 39mm eye size. They are for 76 Toy Landcruiser FJ40. Thank-You
Unfortunately, I just don't have the time. At most, I might be able to design and 3D print the molds for you, but I would need precise measurements. My recommendation is to call Energy Suspension (949-361-3935) and tell them what you need so they can find you a compatible, if not exact, part number to order.
Hello, Derek when I spoke with Kevin at Energy Suspension, he told me I would have to order between 100 -500 and they do not do single orders. Any other Ideas? thanks, AA
Derrick Aquino He did not want to help because he told me just to get started I would have to get the engineering Dept. Involve and that would take a couple thousand dollars.
Derrick Aquino : Hello, my friend they are the bushings for the front of the spring shackle. EMU send the wrong size. I imagine due to the COVID 19 they are making them and they do not make many on the size I need. Thanks AA
@@georgenettlesjr1466 my recommendation is to get a silicone mold making liquid rubber (amzn.to/3aOTiXy, though you may need enough to make 4 individual molds) and mold release (amzn.to/2Qlr8u6) along with the polyurethane mix. Make 4 copies of the rubber pad so that once you mix the polyurethane, you can use it all at once and pour all 4 molds.
Motor mounts are really large, but I'm hoping to do this with differential bushings for my SRT8, then move on to suspension parts as well. Freaking k member bushings are $200, diff are $150 etc, just ridiculous by the time you replace all the the link bushings and such. Car is multilink front and rear, probably 30 bushings, averaging $25/bushing or more. Yuck. can replace the entire arm with rubber bushings for that. Here's an idea I'm curious if you're interested in trying- what about casting an insert for the oem motor mount, other subframe mounts etc, IE how torque solutions does it. That what you don't get much extra NVH until it starts to deflect significantly.
I thought about making inserts, but I think it's just better to fill the stock mounts once you trim out some of the extra rubber per ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DxAL2n7VtMU.html. I don't have any issues with NVH with my mounts.
No, it's been fine in the engine bay sitting next to my header. If you want a softer bushing, order the liquid urethane with the lower durometer rating.
I'm not sure what exactly you need to know, but it's listed as urethane elastomer. I would check www.suspension.com/diymmi. There's some documents linked there. Otherwise, contact the manufacturer.
Yeah, I forget a lot when filming because I have to constantly take my gloves off, hit record, and put them back on. I thought I noted about wearing gloves via text in the video, but I guess not.
I wasn't planning to originally, but you're now the second person asking about motor mounts. I am selling the 95A bushings I took out though if you're interested in those.
Thank you, but I don't have time to make these. I do have the 95A Prothane ones I mention at the beginning of the video up for sale at facebook.com/marketplace/item/881011575810155.
@@VampyreX13 Do you have a moment to make the next video? I'm trying to make custom bushings and I'd like to see how you did it in detail so I don't mess it up. Thanks!
@@Darkvoidproductions1 I'm still trying to get that together. I've been really swamped the past couple of weeks. The only reason I'm still posting weekly videos is because I have a few of them already mostly prepped. I will try to work on this one after this weekend.
It wouldn't be cheap if I did. $48 for the liquid urethane alone plus 3D printer time (it's tied up for my production use), craft oven time (tied up for my girlfriend's production use), and my time. I do have the 95A inserts for sale though if you're interested.
I just don't have the time really. If I did, it probably wouldn't be cheap because of the cost of materials and the amount of time and work I would have to put into it.
@@christopheraustin3324 that's the main problem. It's no longer available anywhere. Your best bet is to look at my other video where I talk about filling your stock mounts.
