Mixing flux issues

[AMBikeCo]

Hi folks

First post on here but I’ve been lurking for a while.

I’m in the process of building my first frame and I am “stuck” on an issue with mixing flux. Until I get it resolved I am reluctant to move past the current practice lug/tube stage.

I am bronze brazing and using SIF 101 flux. For some reason (user error no doubt) I’m really struggling to get a nice, smooth flux paste from the mix. Instead I get this horribly gritty and lumpy mixture.

This is causing all sorts of issues with my practice brazes, mainly because the mixture doesn’t go on well and exhausts/burns very quickly in those areas.

Should I be using warm water to mix? Or mixing on a hob to help it dissolve? Or using the wife’s cake mixer 😀?

My frame is mitered and ready to braze but I’m stuck on this issue.

Thank you for your help in advance.

Use water, any temperature. To pummel hardened flux into submission, I use the end of my 6" square. Or an old file. Anything will work as long as there's enough liquid.

Many thanks, Richard.
