As far as the welding and fabrication skills those can be aquired..all that you need really is a drill press a welder and a cutoff saw..and some grinders..that is all I use to build chassis..On the welding part go get a lincoln or miller SP175 and start welding..once your you can stick 3 pieces of metal together youare good to go...One can find people with good welding skills to come over and finish weld your project.
What building thse rods takes more than anything else is determination and persistence. Dealing with setbacks is part of it as there will be times that you are ready to send the whole thing to the scrapper..Like when you find the parts that you bought don't fit and do not work..
So to summate this is do some searches on the site and look around and you can find ways to get it done..
I have tried most all of it and now do what is known to work..
