Adventures in soldering:The GT40 project New pics 2/13/17
Dave Ambrose replied to Randy D's topic in WIP: Model Cars
Randy, this is a tour de force of my favorite car. Thank you so much for sharing your progress. -
please stop it !
Dave Ambrose replied to b-body fan's topic in General Automotive Talk (Trucks and Cars)
The problem is internal stress in the plastic from the molding process. Best thing to do is to liberally paint the topside of the groove with solvent glue, then let it dry. The plastic will then bulge where it's stressed and you can sand it flat. This process also works for when you shave door handles, emblems, and the like. -
What did you see on the road today?
Dave Ambrose replied to Harry P.'s topic in General Automotive Talk (Trucks and Cars)
My son and I were coming back home from lunch when we saw an early '60s Jaguar sedan on the road, and a '34 Chevy on an auto transporter on the same road within 2 minutes of each other. We decided today was cool car Friday. -
Ideas vrs. talent
Dave Ambrose replied to cobraman's topic in General Automotive Talk (Trucks and Cars)
You know, I'd settle for either one. -
This may be a bit far afield, but there's also the San Diego Model Car Club. We meet on the 3rd Tuesday of the month at the San Diego Automotive Museum in Balboa Park. You can check out our web site at http://www.sdmodelcarclub.org and our Facebook page at https://www.facebook.com/SanDiegoModelCarClub

Plastic chrome plating
Dave Ambrose replied to Greg Wann's topic in General Automotive Talk (Trucks and Cars)
You need 10-4 mm Hg pressure to coat aluminum. That's a long way from 2mm Hg. Vacuum leaks are a constant problem at these pressures (or lack thereof). -
Plastic chrome plating
Dave Ambrose replied to Greg Wann's topic in General Automotive Talk (Trucks and Cars)
It's probably way simpler to send your parts out for plating. What kind of vacuum system do you have? You'll need more than a mechanical pump to vapor deposit aluminum. You should at least have a diffusion(?) pump to get the vacuum low enough. You'll also have to accept that it's going to get dirty enough that you won't be able to do other kinds of vacuum deposition with it. -
I'm so sorry. Moms are special. There's never a good time to lose them.

Applying Clear Lacquers
Dave Ambrose replied to Miatatom's topic in Model Building Questions and Answers
I've been using Testors wet-look clear from the can. I like it a lot. I've also used Future through an airbrush with good results. -
Auto modelers - Left or right brained?
Dave Ambrose replied to Jantrix's topic in The Off-Topic Lounge
46 for me. Apparently, I'm well-balanced. They clearly don't know me very well. -
Are We Model Hoarders?
Dave Ambrose replied to mrmike's topic in General Automotive Talk (Trucks and Cars)
Probably the best way is to find a local model show/swap meet and buy a table. I don't know how many kits you have for sale, but if they're priced right, you'll move a lot of them and net about what you'd get on ebay for a lot less hassle. -

I feel your pain. I have a lot of want-to-do projects where I currently lack the talent to complete them, But the wonderful part is that you can set stretch goals for yourself, and have fun while you're improving your skills. Willingness to re-do things helps a lot. -
What is the color? I'm thinking it would be a great color for a couple of projects in my queue.

Enamel needs a different painting proceedure than lacquer. Put down a very light mist coat before you get serious about putting down color. The mist coat will look terrible and very transparent. Let it dry, give it an extremely light sanding with the finest sandpaper you can find, then lay down color coats. Keep the coats light, and let them dry for 15 minutes before you put down the next coat.

Here's something I learned from a guy who painted spacecraft for a living: Paint the hard to cover areas first. He would get into the nooks and crannies and hit them with paint. Then, he'd go back over the entire whatever, and paint it. When he was done, he'd have perfect coverage. It is a principle that's worked will for me on my models In your case, hit the areas giving you trouble. Leave the rest of the model alone. When it's dry, lightly sand the paint with über fine sandpaper. Then paint normally.

Our new addition. Arrived early.
Dave Ambrose replied to Petetrucker07's topic in The Off-Topic Lounge
Congratulations! Remember this day, my friend. It will be one of your best days ever. I still smile when I think of my children's births. -
Let's just say that if his IQ was a price you would have gotten change from a dollar bill. I once had to swim 17lb of dive weights back to shore. It was tough. At least I had fins and wetsuit. Somebody with no wetsuit or fins and a 10lb rock is doomed.But, why didn't he just let go of the rock?

My first airbrush was Paasche VL set. It was great. You could tackle just about anything with it. We were doing model railroad and the occasional aircraft. When the friend who loaned it to me needed it back, I replaced it with an Iwata Eclipse BC. It worked, but I could never get a nozzle large enough to work well with hobby paint. It was awesome for ink tho. When I got back into cars, I got another VL and have been using it ever since. I mostly use enamels and lacquers.

What did you see on the road today?
Dave Ambrose replied to Harry P.'s topic in General Automotive Talk (Trucks and Cars)
A right-hand drive MG-TC. That made my day. -
I started mine too. It's a fun build. The fit is excellent. I'm at the fill, file, sand, and repeat too many times phase. I'm using Tamiya masking tape on the windows and it seems to be working.

Model kit when flying
Dave Ambrose replied to kangee's topic in General Automotive Talk (Trucks and Cars)
I brought several kits back from Canada, and never had a problem with US Customs, or the TSA. One customs agent asked about a couple of Gundam kits I was bringing back for my daughter. She smiled and said, "Lucky kid." Tools and acrylic paints had to ride in my checked baggage. -
If you haven't already tried this, get a set of close-up lenses that fit your current lens. These allow the camera lens to focus closer. I'm shooting a Canon EOS 60D, with an 18-135mm lens. I normally use a +1 or +2 closeup lens for shooting models. For really small stuff, I might need a +4. You can get them in sets for a reasonable price on Amazon. If you decide you need a new lens, you'll have to get a macro lens. Be prepared for sticker shock.

I know more than a few of us like trains...enjoy this.
Dave Ambrose replied to charlie8575's topic in The Off-Topic Lounge
Thanks for the heads-up. I saw one of these close up in the rail museum in Scranton, PA. They are massive in a way that does not come across in the photographs. I think it's going to be awesome to see this running under its own power again.
