Projects 32 Sedan Lakester roof chop

Do you TIG over the MIG tacks, or stop at them? Is the metal finishing different over one or the other? I really enjoy looking at this work. Bob

 

If you TIG over the top of the MIG tacks, do you find it takes the "temper" out of the hard MIG tacks? I usually don't do that many MIG tacks, but if the TIG seems to remove the hardness, I may start doing more tacks.

How long is each TIG weld? An inch or even more?

 

What kind of equipment do you use to grind those mig tacks. This tread is a real education....many thanks.

 

I tig straight over the mig tacks,i do find it takes the temper out for sure.I am able to move the weld line where i want without fear of cracking as if i welded fully with mig.
one inch to 1.5 inches max i find max without the panel not liking it,especially on this roof.

thanks for the questions and viewing

 

just a quarter inch thick 'cut off' wheel.thanks for reading

 

Love this nice work,looks so good I even like sedans more then I did.

 

Please tell me what you do after you knock down the weld with the grinding wheel. How many more steps are there?

 

after knocking down the weld then,

hammer the weld whilst still hot
then with using a spoon or flapper i plannish 'up' the weld line to the correct shape/profile.
then repeat first step of tig welding 1-1.5" etc

 

Thanks. But how do you get to the final finish?

 

ok then you use a draw file to highlight the 'highs' and 'lows' .you then proceed to use a slapper and various dollies/hand weights to bring up the material/or spread the highs to fill in the 'lows'.
then file,and repeat the process above and file again etc...

 

This is such a great education thread. I just don't understand MIG from the get go. Why does it produce so much unneeded material on top of the metal that you have the heat up the metal to remove? You sure know what you are doing so I guess you can't get a flat MIG weld like a gas or TIG weld. Bob

 

WOW, WOW.....I just can't get over your skills...This is the best information I think I have ever seen posted on any chop and the best skill and workmanship I have ever seen also. Your attention to detail is outstanding. The extra mile on the door hinge is out of site...I could go on and on about what you have done with you metal skills, but I am sure everyone watching is just like me and in total admiration of your craftsmanship and level of talent.
Thanks for posting such great step by step photos.....YOU ARE THE MAN!

 

Totally agree.

 

That's really nice of you to take the time to write that,thank you very much.

 

Today was taken by Tig welding the complete roof.Metal finishing began late in the day.

 

Can we see pictures of the tools you are metal finishing with. You said draw file not sure what that is or if I'm calling it something else. I'm getting close to being able to finish off my welds so I'm keeping a close eye on your work. Keep the pictures coming!!

 

I know its been said countless times but your metal working skills are amazing. Thanks for taking the time to post and giving us helpful tips.

 

ill get snapping photos tomorrow of the tools.I think i should try and do a video of metal finishing a 12" section.

 

metal finishing continued...

 

here you can just make out the shadow of the weld line,because the filler rod is a different colour to the parent material.

 

and wax and grease remover as highlighting fluid

 

Beautiful work. If you have to paint it make it black!

 

it will be black!Painted in Australia so unfortunately wont see the final product!

We are looking for metal workers that can do this kind of work.Compensation upwards of $25-35 p/h depending on your skill set.

 

I think you are correct. Please and thank you

 

How many Pebble Beach winners have rolled out of your shop? Thanks for the daily updates. Bob

Omg a video would be awesome!

 

Absolutely perfect!
