Can I Repair This Alloy At Will Is Still Be Safe?

[Atari Boy 11]

 

 

Would it be possible to use this rim? I have never used it and wondering if it is worth getting it sandblasted and powder coated.

Could I tidy it up and make good with some sort of metal filler before I got it sand blasted and powder coated.

Is there a metal filler that will withstand the heat of an over?

 

Thanks

That doesn't look too bad to me, alot of the marks will come out with a bit of sanding and as you say when it gets blasted.

 

I asked my guy a similar question of behalf of Pugtorque regarding the use of a metal filler prior to powder coating and he said he hadn't ever done it, but the bit that worries me is the possible different rates of expansion once it's in the oven.

 

Sorry I can't help anymore than that.

Epoxy metal will do the trick , most of them are high temp. resistant from 150 up to 300C and this latest formules are really very strong stuff (you can buy some special purpose metal fillers , download Loctite pdf doc. from the net and take a look )... i repaired my cracked block with this epoxy metal and it turned out as good as new , no leaks no falling off for almost a year now ...

^ If that's the case it could be that it'll be okay, have you asked the firm that's doing them their opinion?

 

AFAIK most ovens operate at 200C (Gas mark 6 )

I'd TIG that to build it up and then linish back, once painted you wouldn't know the difference. I certainly wouldn't worry about it safety wise, it is just a curb mark.

.. i tried a little test with the 80 and 300C rated epoxy metal , i used one big screw and nut on the top tighten just a few threads so that theres 5mm hole down in between the end of the bolt and nut , filled the bolt threads and nut hole with the epoxy , waited for spec. drying/hardening time and immersed the bolt-nut in the bucket of boiling water (100C) for 15min. , then i took the bolt-nut out and tried to tight+undo the nut from the bolt -> the 80C rated stuff did soften a bit so i was able to undo the nut a little bit easier , however this wasn't the case when i tried 300C epoxy - was rock solid , i couldn't turn the nut nor a single turn inside or out with fair brutal force

Great, thanks chaps, it will only be the spare on my road rims so

it should not see much action.

I will start looking for some metal epoxy

When I had some wheels powder coated I was told not to use any kind of filler. If you get a tiny air bubble in it, it expands and blows the filler out.

Just spoken to the outfit that will be doing the work, no, I cant use filler as is shrinks and cracks in the oven.

I think I will just try and smooth down and see what it looks like.
