Spot weld removal :(

[Danb1987]

Evening all,

Are the little spot weld bast@rds as hard to get out as im making them look.

Only tried a few so far and already manage to put a hole in my rear 1/4.

Any tips etc.

You must be making hard for yourself

Buy a good quality spot drill bit I got a couple of dormer. I've just removed both quarters, rear panel, sills an other bits an just started on my second bit. I found a battery drill ideal a bit of wd40 ( for lubrication lol ) an go medium speed. Don't push to hard or you'll blunt the bit quick as, basically nice an steady let the drill do the work

cheers Rich

Iv got 2 types of bit. A cutter type one and a traditional style one. The cutter just jumps around even though iv drilled pilot divets.

Looking at that article it seems theres little way of stopping the drill sometimes going though both panels.

I guess itl just take a bit more time with the welder.

If it's like the one I brought from machine mart bin it there crap. Stick with a standard one an pay a bit more it's a good investment while you own a nova lol. Once you've a done a few you'll get the hang of it. When you think you're nearly through stop get a thin flat blade an slide it between the panels an give it wiggle then you'll see if you need to go some more

Going thought is totally normal. Dont worry about it.

it takes a bit of experience to feel when you have only went through one panel,
as said earlier the Dormer ones are great and what I use too,

Drill until you see rust that means you reached level 2 I must of drilled close to 300 on my van

You want the 8mm 'regular' looking drill bit with a slightly flatter head

If you can pry the panel a little bit you'll feel when you're through the top layer as it'll ping slightly, but rust is a good indication.

If in doubt, stop early and continue with the others, then pry and drill the final bits one by one as necessary.

Thin metal to thin metal is easy (1mm on 1mm) but thicker stuff like seat brackets are a pain.

Going through is definitely not normal. As already mentioned just take your time. If its an 8mm spot use a 10mm bit.

Im halfway through gutting a Clio, so far have done 147 spots and only on the second bit (Dormer).

Agree get a larger bit and dont get cheap ones! everyone seems to recommend Dormer...

I found the more you try and push the more bits you get through and holes you make...

[Iain]

I think I ended up using screwfix ones

[8valve-craig]

Also make minor adjustments on low speed until your bit scrapes a perfect circle, then keep it steady and you know you are drilling straight.

I fount this style of drill the best, takes practise to drill the top skin only. The higher the quality of the drill the better, I have 6mm and 8mm diameter

Should never ever go through both skins! As said,take ya time.Use a bit of oil too.Oh and speaking from experience dont buy the strap on ones unless you are drilling chocolate spot welds.They are truly dog faeces.

Ask a mate in a body shop I bagged 10 bits for nowt

Ask a mate in a body shop I bagged 10 bits for nowt. An electric drill has a speed adjuster on the power button that is handy
