I was thinking of having the 4130 parts powder coated but I am worried that the oven baking may change the temper of the parts. Is there another method of coating the steel parts that will stand up to wear and tear?

John,
The powder coating oven doesn't get hot enough to adversely effect your welded parts. It should only see about 500 degrees momentarily.
Powder coating is good for non moving parts but things like your front gear strut I would go with a chrome plating.
Be sure you tell the Plater to "Bake off the Hydrogen" to avoid embrittlement.
If he doesn't know what you are talking about find another Chrome plater.

Hello John,
In my factory we have powder coating, I am no expert but can tell you what I have learned in this 20 plus years...
There is no problem with the heat of the oven to the 4130, our is set at 180 ºC (about 356ºF) so will not do any harm. BUT I did not powder coated the 701 (or the 601XL wea re building) parts, because there is one risk.
A well aplied coat of paint will make a "thick" cover over the material, the paint is more flexible that the 4130, so IF a little crack beguins to develope, the paint will not let you see it in the beguining.
Another thing is I always paint the engine mount white, is easyer to see any cracking even in the beguining.
Hope this helps
Saludos
