Stew's build thread

[stew]

Its taken me forever tonight to do the front frame!

Ive found it a right PITA to get all the angles dead on, and all tacked up exactly square, and thats even with using a jig.

Finally was pleased with how it turned out, so fitted it to the base of the chassis. Im still on target for being exact dimensions to the book.



I then got bored, so cut a test coupon of 25x25x2mm RHS, and welded it. It seemed to run in quite well, the weld seemed wet enough, and was hot enough.



I then sliced and polished the cross section, and it just shows that even with a decent looking weld, its still very important to check the weld has penetrated the back surface properly. This is something we do at work regularly, and keeps us all on our toes! Nothing worse than a poorly penetrated weld.





For welding up the chassis i will step-up the voltage one click and corresponding wire feed speed.

Thats all for tonight, will get the rest of the front end of the chassis base finished tomorrow, and then start on the uprights and take it from there...
