Looking for anyone with experience using brass for sliding rail mechanisms such as sliding canopies. Metal to metal contact with potential for vibration is a big no-no due to the RF interference caused. But, it appears that many are using brass when constructing sliding mechanisms in RC aircraft.

Brass is non-ferrous, so technically, it makes sense that it would not cause electro-magnetic resonance fields resulting in RF interference like ferrous metals can. But, I'd like to find someone with experience using brass on brass in such a way. RF problems in your experience?

I'm not doing a sliding canopy at this time, but have another sliding mechanism I want to use a brass tube inside a brass tube for. Want to be sure I'm not going to run into RF issues.

Thanks!

Tom,
I can advise that myself and many other scale modellers down under have been using brass rails with brass inserts and had no problems with Rf interferrence at all.

My background in case you are curious is Electronic Engineering.

If you want to be really pedantic you could ties the rails to the negative rail on your battery pack to enure all is at the same potential.

good luck with your build, your posts and building add much to the forum.

cheers

Thanks Peter, I figured as much, but just didn't have that "warm and fuzzy feeling" about it yet. I'm sure it will be OK, but it helps to draw from the experience of others when exploring uncharted territory.

Cheers,

Tom

Tom,

this is all very true and if you don't ask you never learn.

Hi Tom...

Its good to see you back in here, haven't seen you around or you have been hanging out in other places.

I am a big fan of your work, and have read through your Hangar37 site many times before it went down (or i lost it), thanks for
all the ideas and inspiration.

What are you working on now?


Cheers

The brass rail that I put on my yellow P40 is brass with the plastic insert so no problem there.

Couldn't agree more. BTW, I was checking out your P47 thread last night... Awesome! Very impressive work.[sm=thumbup.gif] I'm going to spend a few more hours just reading through. Share and share alike eh?


Goose,

Thanks for the words. My site is still up, just moved it... [link]http://www.tompierce.net[/link]
Right now I'm working on an 82" Jack Devine FW190 A-7 kit. I've got a new build site up for it too, just like I did for the SBD project... [link]http://www.tompierce.net/190[/link] Stop by some time, I'll leave the light on for ya!



I've got a build thread going on it [link=http://www.rcuniverse.com/forum/m_4129416/anchors_4129416/mpage_1/key_/anchor/tm.htm#4129416]here[/link] and at [link=http://www.rcscalebuilder.com/forum/forum_posts.asp?TID=5416&PN=1&TPN=1]RCSB[/link].

Serpente,

Yeah, I knew it would be OK with plastic inserts, but I need to use a brass tube inside a brass tube on this one. It was the brass to brass issue that I was worried about.

Thanks guys,

Tom

thanks Tom, that is agreat compliment coming from you. Guess this is what the forum is all about, swapping ideas and providing comraderie. As we can't all get together and do it in person this provides the next best thing plus it also provides a great repository of information all neatly packaged!

Off to help ticketec do some glass work later.
cheers

NEO, How did you do the art work for your side view of the FW on your new build site. Looks real good... as if you do CAD for a living?

Furbird,

Not sure which image you are talking about? If you mean the one that is shown here a couple posts above this one, I didn't do it. That's a color plate by Simon Schatz. Color plates like that are readily available in books and on the web everywhere for choosing and documenting authentic color schemes. I also have photographs of a 1/48 scale plastic model (on my site) that I built and painted using this scheme too... is there a different image you're talking about? I can't think of anything else you'd be referring to?

BTW, I am a graphic designer/artist for a living. I could have made this illustration if I needed to, but why do all the work when someone else has already done it?

that is what I reckon too, why bark if there is a dog to bark for you!

Great!

I will be watching and learning from this one too...

Thanks!
