I just finished up an SC motor job today for a customer. It was a father and son project car, and they really wanted to " help" .
The only way I could possibly do this was to work weekends, so 6 weekends later, we are done. I am not so sure that their help really sped up the process in any way. I gave them full use of my shop, all my tools, and I walked them through every step along the way, explaining each different process involved.
It was basically like a 911 engine rebuild class. I did the whole enchilada, pulled it , tore it down, measured up everything, boxed it all up , shipped out what needed machining, assembled, installed, and tuned. I made all the parts orders, and gave them shop discount, most likely saving them a bundle. I treated them very fairly .
Should the labor be discounted because they helped? Should they be charged more because, I basically showed them every trick I had in my book , gave them free roam of my shop, tools, and experience, on the weekends, and I even had to repair a few blunders made by them. Or just plain old shop rate?
Just wanted to hear how you would expect to be treated in this situation . Thanks.
