The holes you see in the inner sill are “lightening holes” they add structural strength to a long metal structure and are used extensively in aviation. You will note that they are not just holes drilled through but have flanges which were made during pressing of the part. Drilling a hole through your repair would have been a mistake as there would have been no flange and could eventually start to crack. Good stuff though really impressed with your tin bashing 👍😀
listening to the welder, it sounds like you got the settings just right...I have to say though at 12:43 you committed an engineering cardinal sin.."thy must pat the object twice before proclaiming...that's not going anywhere" 😂
lol I’ll remember that. Yes I think welder is set correctly for this thickness metal, main issue was not cleaning surfaces enough. Live and learn! Thanks for watching :)
Great progress. Its amazing how time consuming fabricating and welding patches in is. If you've got lots of this to do, you might want to invest in a finger sander, they're great for getting in to the details.
Looking better!! I like following your series. Curious if you have access to a "finger" belt sander? (Evolution UK, Amazon UK are good sources). I'd suggest this for preparing weld surfaces, grinding down welds, and a weld thru primer like Upol.
Hi Stefan, thanks for watching! no I dont have a finger sander, about to look it up. I do have weld-thru primer and Im guessing I should have used it...
lol thanks Christian, i think :) yes, Im a hobby welder, definitely not a pro... I don't do it often enough to get into the flow. But yes, its strong and hidden. Thanks for watching and commenting. The next episode will be the outer sill, which that seam weld along the top (and my grinder to make it flat :) ).
your welds are not hot enough ,,, this is heavy going working on the floor , a ramp makes life a lot easier , but keep at it and you will get there . A weed sprayer full of water is a mighty handy thing to keep to hand too ,, just a thought. But not waxol ,,, anything but waxol .
Thanks Tom. I was worried that if I turn up the power it will blow through, the sill is only 1mm or so. Or do you mean to move slower to build up heat?
@@MrToddgibbs more volts and / or less wire ,,, hotter but tack faster is the way to go , your welds on that sort of stuff should just about lay flat ,,, the odd burn through wont matter , let it cool and spot it in again , at least with a burn through you can be 100% ure you have good penetration , I do a lot of this stuff , normally on landrovers
@@MrToddgibbs if your not getting the results you expect go take a look at jody , welding tips and tricks , he does a lot of great mig welding videos ,, or drop me a note ,,, if I can point at anything I will.
