Making headers with solder
Posted by JohnDB on Wednesday, January 31, 2018 8:14 AM

Was just wondering what diameter solder do you use to make headers? Thanks in advance for any and all responses.

1/16 inch (.062") scales out to just over 1.5 inches in 1/24 or 1/25 scale, and is an excellent size for the primary pipes of all high performance engines except big block v-8 and large bore all-out race engines. You could still get away with this size for a mild street big block.

The next common solder size is 3/32 inch (.094") which scales out to almost 2.4 inches, which really is too large for header primary pipes for most engines except for perhaps seriously high output drage race engines.

I haven't searched for solder in metric sizes, but if it is available in 2 mm diameter (which equals 2 inches in scale), it would be a much better size for big block race engines.

If you can find it, solid core solder is the best to use. Solid core can be difficult to find so you will likely end up with rosin core or flux core solder. These caustic materials (acids) can leach out of the ends of the cut solder pieces long after the model has been built, so when making any model part out of solder, be sure to cap the cut ends with a drop of CA glue to seal in the nasty stuff. If the flux/rosin gets onto painted model parts, it will spread around and ruin them.

Thanks Bainford, I am pretty sure that is everything I could possibly need to know. I really appreciate it.
