hawkwrench Posted December 11, 2013 Share Posted December 11, 2013 (edited) The 1/35 scale H-60 Hawk family of kits are pretty nice and with aftermarket PE and detail sets, it builds into a good looking model that's looks realistic except for 2 areas: 1) HIRSS 2) Rotor Head I've always wanted to build a better detailed rotor head, but never tried until now. Please be patient with me as I don't get much time to model as I would like but I will post in-progress pics as I move along in the build. Here's all the kit parts minus the PC rods. Hopefully I can take it from that to a pretty good model of this: Thanks for looking! Tim Edited December 11, 2013 by hawkwrench Quote Link to post Share on other sites
strikeeagle801 Posted December 11, 2013 Share Posted December 11, 2013 I'm going to follow along here. I tried to scratch my own main rotor shaft, but I want to see what you do with it. Is this something you would consider mass-marketing like the transmission that came out a little while ago? Aaron Quote Link to post Share on other sites
hawkwrench Posted December 11, 2013 Author Share Posted December 11, 2013 It all depends who would be interested in producing it considering the hub might have to be made out of white metal, but if the detail is liked by whoever such as CC or WW, then yes I would consider having it as part of a covers ion set.

norbert Posted December 12, 2013 Share Posted December 12, 2013 Hi Eduard PE is great in order to make good looking weights Norbert Quote Link to post Share on other sites
Chief Snake Posted December 14, 2013 Share Posted December 14, 2013 (edited) Like I said in the email, building to put on your model is not the same as building for casting. Parts immersed in RTV will be subject to free standing envelopment and interlock. Free standing envelopment will happen with the pitch change horns, these pieces will break off when trying to free the entire assembly from the RTV. This means a two part mold is likely. The next problem is interlock. Anything that is not solid will create an interlock in a mold. No Matter what kind of mold. If I remember correctly the Eduard weight covers are hollow. This is interlock. There is no way to pull any such piece out of a mold without breaking it. You should begin to think about creative ways around these problems. In the Cobra Company white metal heads in 1/48th scale we resorted to artistic license. A depiction of the real thing engineered to avoid the envelopment and interlock issues. Try to envision these circumstances with each piece. It may be better to NOT put the pieces on but cast them individually and then add them to the master hub. Creating a better looking rotor mast can be done on a lathe, using any kind of stock. Chris M Edited December 14, 2013 by Chief Snake Quote Link to post Share on other sites
hawkwrench Posted December 14, 2013 Author Share Posted December 14, 2013 That's a good idea Chris. I guess it will turn into a mini-model, but it will be worth it I'm sure. Tim Quote Link to post Share on other sites
HeavyArty Posted December 14, 2013 Share Posted December 14, 2013 (edited) I'm all for a new rotorhead. I just picked up a MH-60L kit cheap on eBay, but it is missing the rotor head. So I will be a buyer if/when you get this worked out. If anyone reading this has a partial, broken, incomplete, or left over from another project rotorhead and/or blades, let me know. It looks like I will be needing one. Edited December 14, 2013 by HeavyArty Quote Link to post Share on other sites

I have some blades but I will have to see how many I have. Chris M Update: I have all the pieces, rotor mast and 4 blades. You can have them.

hawkwrench Posted July 8, 2015 Author Share Posted July 8, 2015 Well, with CC MH-60M set on hold, I'm starting to play around with building a new head. Can somebody do me a favor and mic out the width of the model's main rotor hub. I'm at work and can't, otherwise I would do it myself. Once I find out the size, I can order what size tubing I need to build it. Thanks, Tim Quote Link to post Share on other sites
anvil6 Posted July 9, 2015 Share Posted July 9, 2015 i'll be following this one for sure. i built a h-60 rotor head a few years ago in 3d, but it is not nearly as accurate as it needs to be. i might revisit it as i too have been wanting a better rotor head. the first OCD thing to tackle is that the arms actually point up from center by a few degrees, not straight out as depicted in the kit. good luck, i look forward to seeing how you solve this problem! :) -Ramon Quote Link to post Share on other sites
CW4 Erick Swanberg Posted July 9, 2015 Share Posted July 9, 2015 I believe I have a solution to the Hirss issue that I have been working on with my Sierra model and it looks like it is a easy fix and wont take alot of time to do and no additional parts. I am working on the tip right now and will publish it here in a few days. Erick Quote Link to post Share on other sites

hawkwrench Posted July 10, 2015 Author Share Posted July 10, 2015 Ok, I found out on my own. I need 1/4 round tubing for the start of the hub. Tim Quote Link to post Share on other sites

I just ordered the tubing needed for the hub. Now on to the swashplate. Preaching at my church Sunday morning, then I'll be able to start on making the swashplate. It will be a combination of kit parts, PE and scratchbuilding new details. Tim Quote Link to post Share on other sites
zerosystem Posted November 3, 2015 Share Posted November 3, 2015 Any updates? Quote Link to post Share on other sites
torchf4 Posted November 7, 2015 Share Posted November 7, 2015 Here's to hoping someone eventually makes an aftermarket rotor head for the H-60 series, especially a folded one for the MH-60s and navy variants. Quote Link to post Share on other sites
Youngtiger1 Posted November 13, 2015 Share Posted November 13, 2015 Yeah, it will be nice to see what become of this project. Come on Tim To be honest, I'm bit surprise that someone with CAD skills and a 3D printer hasn't create a detail rotor head already. Considering how much stuff is coming out every month that is direct result of these computer programs. <_< Quote Link to post Share on other sites
hawkwrench Posted November 28, 2015 Author Share Posted November 28, 2015 Don't think I haven't been ignoring you guys or that this is a dead post, but life is WAY!!!! to hectic anymore for me. I did manage to work a little bit on the detail set while on lunch at work. 1- The swashplate on the real H-60 only has 3 connecting links, but on the model there are 4. ( The small oval holes in the inside of the model piece). So I got out my handy fancy Dremel and ground away 1 of the links leaving the correct 3. Sorry for the bad lighting and backdrop, Its a table. I've also been working on the rotor hub itself. I cut off the kit hubs and replaced them with styrene tubing glued in place at the proper 8 degree upward pitch. It might not be much, but it's progress! Hope to have more tomorrow night!

Youngtiger1 Posted November 28, 2015 Share Posted November 28, 2015 Great work Tim. How did you manage to achieve 8 degree upward pitch on the hub? Do you have a tool that can cut styrene at different angles? TIA Mike Quote Link to post Share on other sites
hawkwrench Posted November 28, 2015 Author Share Posted November 28, 2015 (edited) Just a simple miter saw with a few minor angle measurements. And a little MK1 eyeball thrown in for good measure! Tim Edited November 28, 2015 by hawkwrench Quote Link to post Share on other sites

One of the reasons I've never built a 1/35 Hawk is that the HIRSS is so badly botched. I know Norbert was able to correct this on one of his old builds but it was just too much work. Very curious what you came up with. Quote Link to post Share on other sites

Hopefully by January i can actually get back to my hawk builds so keep posting so i can see how its done and follow along! :D/> -Ramon Quote Link to post Share on other sites
hawkwrench Posted December 7, 2015 Author Share Posted December 7, 2015 (edited) Just a little progress update. I made 1 of 3 connecting link rod ends that attach the stationary swashplate to the forward, aft and lateral links on the bridge.-still 2 more to go! I also added sheet styrene strips onto the lower PC rod attachment points, puttied and sanded to shape. I still have to make the other 3 though, wish me luck. Sorry about the backdrop, I can't bring my cutting mat to work, it won't fit in my bag! At least I'm getting to work on my model!!!😁 Tim Edited December 7, 2015 by hawkwrench Quote Link to post Share on other sites
