Hi,

I am re-purposing an old track frame for a fixie. One thing I want to do is silver braze on the number 84 on the head tube. This was my late son's number and I am doing it in his memory. The numbers are .032" thick nickel brass and are 3/4" high. They will be bent to match the tube. How do I hold them in place to silver braze? I don't want them to move while I heat them and apply the alloy. Any suggestions that will hold them in place, but won't get in the way of the braze?

Ride Safe,

Joe
