Re: Re:Purging and Deletion of Topics/Threads

very disappointing. Went to a lot of trouble building a topic on my Falcon build, lighting, painting techniques - TWICE, after photobucket pulled their extortion stunt - just to find out now that it's been erased / pruned. I cannot fathom why those genre forums are being so ruthlessly erased. So man...

A lot depends on who produces the kit. I have some which require a lot of work to get the pieces to fit well, others (like Atomic City/Captain Cardboard) look like styrene kits just from a different material. Emphatically this. Be aware of or research the quality of the products of the maker. A pou...

The pin locations above and to the rear of the trigger opening and the shape of the trigger guard certainly look like a S&W to me and the sizing ought to be a K-frame. Pachmayr grips for it should have a Pachmayr logo / medallion. Were it a Colt, the grip might have had a Colt medallion instead. Pac...

I don't think that's a casting defect you are trying to fix, rather that it's an accurate casting. The threaded insert opposing that grip retention screw falls right against the Pachmayr logo on those 64/66 model S&W revolvers, on those old-skool grips. It's larger than the screwhead and Pachmayr di...

Sand the ends of the bulbs AND use at least one layer of diffusing material. Indirect lighting works great too. Don't point the ends of the bulbs at the 'exhaust'.

Re: Cheap paint brush holder

Instead of throwing away the covers to your rattle cans.... turn them into paint brush holders. I did it by cutting out a notch, across from each other, on the cover. These notches will allow you to lay a paint brush across the cover and out of harms way while you are using it. So while I am brushi...

Those under tight noise constraints should consider a CO2 tank with a pressure regulator. You can run your airbrush for a VERY long time in this manner and refills are inexpensive.

I know how to calculate resistors for a parallel or serial configuration, but I am not sure how to go about adding the resistor between the power supply and a parallel circuit already built. In parallel you want one resistor per led, but as I explained above, I can't do it. It will have to be one r...

the smoother the undercoat and the lighter application of ALCLAD the better. You can get some amazing results with it using 5-6 very light passes, building up the reflectivity a bit at a time. If you go for full coverage in 1 pass or two, you might as well be spraying krylon. 'Chrome' on a PVC pipe ...

Just use the thick carbide disks. The trick to it is let the speed do the cutting. Do NOT bear down on the cutting bit. If things start to glow you are applying too much pressure. Letting speed do the work will preserve the bearings in your dremel, which don't hold up well to severe side-loading (pr...

If you're referring to shining a light source on the side of a strand of fiber, or counting on light spreading / shining out from it, that's kind of the opposite from how fiber is meant to work. It's generally meant to carry light from one end to the other with minimal transmission thru the sides of...

you have to put a known voltage to it and measure the output at the other end. But if it's shorted at the mounting that won't work. If it's burned out but shorted on the board, you'd still get the continuity. I really don't see a ready way to tell, short of dismounting it. And if you're going to tha...
