S800 Rat Rod: Chassis and scratch-built exhaust

The engine is assembled and installed in the chassis. The added length corresponds to the length of the short block, only 15" at 1:1. 



The exhaust consists of two manifolds and collectors from the S800 kits, joined to brass side pipes. 



K&S brass thinwall tubing is lovely: the 0.5 mm rod is a snug fit inside the 1.0 mm tube, which in turn is a snug fit inside the 1.5 mm tube, and so on. 



So the collectors were drilled out 0.020" for a 0.5 mm pin; this was inserted into 1.5 mm tube with a short bit of 1.0 mm tube inserted to space it out.



Tube bending is made easy with the spring-type tube bender, which I have managed to bend permanently.





Stay tuned! More to come.
