    Ham radio and model building

    in Model Building Questions and Answers

    Posted

    Does anyone know of any DMR talkgroups for model building discusstion? I know there are some ham radio operators here on forum.  I'm looking for discussions about model building on DMR radio. (Digital Mobile Radio). DMR has "talkgroups" sometimes dedicated to discussions of hobbies or interests.  One night I listened to a Net (discussion) of amateur astronomers and it was fascinating. For some reason ham radio and astronomy attract similar people.  I thought, maybe that may be true for the model building hobby.

    Thanks,

    gluing metal rod trim KR200

    in Model Building Questions and Answers

    Posted

    I'm building a Gunze Messerschmitt kr200.  Some of the trim is PE and some is metal rod.  I've read lots of posts and like the idea of Future for glue. But, since the rod is round, I thought I would try dipping the rod in Future and draining excess by touching the end to a paper towel, much like dipping windows.  Would there still be too much excess that it would pool around the rod? Maybe wait until the Future is tacky before attaching.

    I also considered sanding one side flat, but I'm not sure I can do that successfully, especially since some of the rod is curved.

    I need to practice with paper clip wire on some styrene.  Has anyone attached metal rod to styrene? (the pics are not my build, but show the rod well.)

    Thanks,

    Dave

    Deepening Panel Lines

    in Model Building Questions and Answers

    Errors

    I use two tools. I start with a scribing tool like:

    https://www.squadron.com/model-building-tools-and-supplies-s/2522.htm#?filters=page=1|SearchWithin=scribing tool

    The angle of tip gives me more control as I pull the tool. I've found that using just the scribing tool results in a wider, unrealistic panel line, so after the line is established, I switch to the back of a #11 blade.  I have also ruined several models.  For me the key is starting with a VERY light touch, much like cutting BMF with a new scalpel blade.  My mistakes come from not concentrating or getting too excited while doing it.

    Wow, superb build David! Having been born just after WW2 I was getting into cars about the age of seven and there were a lot of these and Messerschmitt bubble cars in the UK. The way that they were parked facing the pavement helped get out onto the pathway and two, you could get two in an ordinary parking space, as you can now with the Smart car.

    The Messerschmitt top was made from the fighter aircraft canopy.

    Both the Isetta and messerschmitt were powered by single cylinder two stroke motorcycle engines, noisy and smoky!

    BTW, that's a great job.  One of your builds?  Who produced that kit?  You've given me an idea for color choice on the one I bought.

    I just bought a messerschmitt (gunze). I really like the old quirky cars.I'm going to build a Bentley Blower next.  I've also recently bought a Fiat Mefistofele (Italeri). I'm working up th courage to build it.

    My 6th model. The most fun of any model so far.  Next will be the Bentley Blower.

    First use of Alclad (love the stuff).  First successful two tone.

    The fit of Revell Germany models is just perfect.

    Paint Booths & Safe Ventilation?

    in Tips, Tricks, and Tutorials

    Posted

    Hi, thanks for your reply! attached is the spray booth...over the weekend i was using ZeroPaints, both paints and primers, some alclad II paints, tamiya paints, tamiya airbrush cleaner and alclad airbrush cleaner (these smell the worst)..

    I think next time I need to make sure I go deeper inside the booth when spraying..I also probably could clean the filter..or even replace it..and close the room door when working to make sure it does not spread to the whole flat..I mean I smelled in my bedroom when going to bed...yuck :D

    I have the same booth.  I've had some minor issues with fumes, but usually, as you said, it's often when I'm not spraying far enough inside the booth.  Also, the amount of bends in your vent pipe affects the efficiency of the air flow; keep the vent pipe as straight as possible.   I've found that vacuuming the filter and changing it more often helps.  Also, seal as much as possible around the flange that goes in the window.  You could open another (opposite) window in your abode to increase airflow. (learned this from smoking cigars)  Definitely protect your lungs.  My brother is a chemist in the paint industry and has told me some horror stories about paints and coworkers.

    I found similar filter material here:

    https://www.amazon.com/gp/product/B00NF2V70W/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

    It's cheaper, but not exactly the same as the premade filters, but it's just for overspray.

    Hope this helps,

    Dave

    Testors paint sandy feeling finish

    in Model Building Questions and Answers

    Posted

    Uh, IIRC (If I Recall Correctly), Testors light earth is a flat finish paint--entended primarily for military models--as such it would be a very fine "grainy" finish.

    Art

    Yes, it is a flat finish.  But the "grains" on the suitcase could be rubbed off.  So I tend to agree with BigTallDad, that I sprayed at too great a distance.  However, I did the same with the sprue and it was a normal flat finish.  Also the suitcase didn't become "grainy" until several coats were applied.  Anywho, I think it's operator error.  I'm satisfied with the final result.  I thought maybe the many soaks in brake fluid and cleanup with Bleach White may have damaged the plastic.  (One mounting post on the inside did crack a little when I stuck a toothpick in it to paint).  Time to declare victory and move on.

    Thanks for your reply

    Testors paint sandy feeling finish

    You might be holding the spray can too far away, and the paint is drying in mid-air.

    It looks like that to me too, like overspray.  It was decanted and sprayed through an airbrush.  It didn't behave that way on the piece of sprue.  The first time I sprayed a wet coat and it still looked grainy as it dried.  I think I'll try your advice, lower pressure and spray closer.

    Thanks

    more info

    I'm painting the little suitcase that's in the Revell Germany model of the Isetta.  Started with Tamiya fine white primer and then Testors Light Earth spray decanted.

    Three tries now (after brake fluid strip) and the Light Earth leaves a "sandy" feeling finish that can be rubbed down to SG. I'm applying VERY light coats because I thought the paint was crazing, but this feels different. The last time I sprayed, I did it without primer and the same thing happened.

    I pulled out the sprue that the piece came off of and sprayed it and it was perfectly normal, The Light Earth leaving a perfectly smooth flat finish.

    Stumped.

    additional info and pics:

    Each strip was a soak in brake fluid, then Bleachewhite, then scrub with soap & water. After each strip and cleanup, the surface of the suitcase was perfectly smooth, just like it came off of the sprue.   I sprayed the sprue many ways: light coats, med wet coats, heavy wet coats to the point of running.  Each one was just fine.

    The first time I sprayed the suitcase,  I thought the paint would level out and I kept building coats to achieve a wet coat.  It still got grainy like this.

    '60 Vette

    NIce build on what I remember as a difficult kit to build. To me, it seemed like the parts didn't fit well.

    You got that right!  Neither the front or rear pieces below the bumpers were even close to fitting.  I glued and puttied the rear one before painting, counter to the instructions.  I had to leave the front one off until fitting the chassis.  But I had to putty and reshape it as best as I could to make it mate and to close gaps around the front grille.  (much adult vocabulary).  I'm still a beginner so it gave me practice making pieces/parts fit.

    I agree, nice foil work Dave, and a nice build overall.

    I just bought that kit to build next year. Thanks for the warning on the fitment issues.

    The bottom edge of the tail is a separate piece. Directions said to install it after the chassis was in place, but I installed it before; worked fine.  I had to putty it in and sand it before painting.  Same with the bottom piece below the front grill; major fitment issues.  I did have to install it after fitting the chassis, but it required putty to fill gaps around the grille. Hope this helps.
