CHRIS CRAFT COMMANDER FORUM ® .......A photo-intensive technical reference file and ongoing newsletter regarding the original fiberglass Chris-Craft Commander series. This is an independent not-for-profit and non-commercial web site, not affiliated with the Chris Craft Commander Club ~~ or ~~ Chris-Craft Corporation. Our mission here is to "have fun and share information" about the Commander series (and those associated fiberglass boats on the Chris-Craft family tree) for your individual personal use, and by doing so help promote the good name of Chris-Craft, and help preserve, restore, and appreciate Chris-Craft boats. The main reference feature is the ever expanding MASTER INDEX File which contains what we believe to be the world's largest collection of documentation photos and technical information on the Chris-Craft Commander line of boats, (like these original brochure scans, featuring the iconic first 38 Commander styled by Fred Hudson, and many of the great Dick Avery renditions that followed) , (a huge collection of Chris-Craft 427 tuning and specification information), and a few words about how to use the forum.

We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common ! Just start by posting a note introducing yourself to the group, that's all it takes here (we don't ask for or retain any personal information here, because our intention is to just "have fun and share information".

Response to Re: What is the issue converting gasoline tanks to diesel ?

You can make an empty gas tank safe if you fill the tank with argon or nitrogen and keep the inert gas flowing at a low rate while doing the work. This includes welding and or drilling-cutting.

Personally, I prefer the argon. It is quite heavy and tends to stay pooled in the tank as long as you keep the openings on top, just like if it is filled with water. The nitrogen has a tendency to mix with the atmosphere so requires a higher flow rate.

This method is also much safer than just filling a tank with water as filling with water can leave air pockets with gas fumes. The inert gas method prevents the accumulation of air pockets containing gas fumes.

A couple of per-cautions, you need to have a way to verify that atmosphere inside the tank will not support combustion and that there is sufficient ventilation to prevent the inert gas from flooding the compartment that you are working in.
