David's Build Thread

Hi David,
+ one with all the above.
Definately sort out the welder on scrap plate before doing any tacking.
Too much wire speed will result in the welder back firing as such with pieces of arced out wire all over the place. Setting the "Heat control" as I call it too low will also give similar results but with the wire just arcing and not burning the copper off.
It's hard for somebody to tell you what settings to use as each welder is different.
Basically play about with the settings untill you get a convex (domed) weld with the thickness (parent metal) you are using in the position you are going to weld.
Too higher wire speed and to lower voltage will result in wire just laying on the metal with arc marks here and there.
Too higher voltage and not enough wire speed will result in the wire burning back to the tip and melting wire to the tip and possibly holes in parent metal.
It also depends on what type of shielding gas you are using, and how much is coming out. Too much gas and it will cool the weld too much as you are welding, too little gas and you will have porousity in the weld.

I know it sounds complicated but as long as you practice on scrap metal first it should be OK.
You want a nice "crackle" to the weld when it's set up right like you're frying sausages.....LOL
If you are burning out tips turn up the wire speed or turn down the voltage. Too much voltage and too higher wire speed will not burn out tips normally.

thanks for all the help.

I dropped the parts off with my mate this morning who is an offshore welder! he did find my welds amusing but is going to do them properly for a couple of pints of stella!! bonus. I am still going to master welding though as i am bound to need to do some more somewhere on the build.

Hi David,
Nice feeling when you drop the engine in, big grin factor time for that mile stone....
It's a sad day when you gotta take it out again though to put other stuff in...
I guess it's all woth it in the end.

Looking good there David.......Johno

When installing the fuel lines I am going to use 8 mm micro bore pipe, however is this the ID or OD? I want to buy the right size p clips.

Thanks

David

Usually fuel lines are listed by the size of the bore not the od.

Just measured mine - it's 8mm external diameter.

[Davidbolam]

Thanks for the measurement skov.

I am about to put in place my suspension. What height should I adjust the chassis to? Is it the same front and back?

David

[Davidbolam]

My mounts were dropped off yesterday by my mate. Really pleased with the quality of the welding. Much better than my effort. Just need a coat of paint then to stick them back in the car



I have also installed my suspension but it will need to be adjusted. If I compress the spring will the chassis go up or down (probably a stupid question)

[Davidbolam]

Why won't my pictures show?

Works for me Builds looking good.
