Thanks Mike, there are still alot of joints that need dressed, but most look presentable for photos, anyway. Once all the solder work is done, I'll clean the whole frame and scotchbrite it in preparation for primer. Getting close, now...Formulamike wrote:Great Soldering work,

I agree, I am still searching for the perfect tire to copy for the Cobra... I may end up using a wider tire that has the correct profile and sectioning it to the right width and then cast it. I really want a real rubber tire for this build, so I'm still searching, as well. I hate to have to make the perfect tire, but if I have to, oh well...model.maker wrote:Strevo over on SMC forums offered to make me up some 3D cad models to make a rapid prototype from , I'm going to wait and see what might still turn up on Ebay etc as the tires on the 1/8th scale GMP Gurney Eagle F1 are perfect , I just don't see the point in producing an expensive mold when a pattern can be sourced elsewhere.

Yes same here the tires will make or break any miniature in particular an open wheeler F1 like the Brabham , I"ll keep an eye out for you anyway.bmwmech1 wrote:I agree, I am still searching for the perfect tire to copy for the Cobra...

The solder is just garden variety stuff, not silver or anything fancy, in various diameters. Too cheap or lazy to hunt for anything fancier, Lol...The torch/iron is actually a variety of tools... a couple of different size torches, a non-fancy weller iron and an American Beauty resistance rig. Surprisingly, I use torches most often, since all of the round "tubing" is actually solid rod. It takes a bunch to heat up 1/2" diameter brass, so the resistance setup is only used for tubing, where multiple joints in close proximity need to be soldered. I just jig everything, if I have to re-solder the larger rod, so I don't lose any previous joints... It's pretty crude, but I'm no purist when it comes to soldering. The results are more important than the methods, to me, anyway.model.maker wrote:Out of interest what melting point Silver solder and torch/Iron are you using in the Chassis construction ?
