Need advice on how to rivet back bolster in fixed blade.

Hi. The Tutorial shows the process of peening the tang over the bolster. That's what the writer means by rivet the bolster.

I used the same tutorial for the one I made.

Best regards

How do I do that then? Just beat the steel tang?

How much of the tang should be sticking out before I start peening it?

leave couple mm of tang(some advice is to leave as much as width of tang),don't beat it,light but constant tapping with will do the job(you may have to soften the tang before peening)
 
You can also countersink the hole at the end of the pommel. This will allow the rivet to be flush with the pommel and still hold the handle in place. For additional security you can use JB weld to glue the pommel in place before peening the rivet.
 
How can I soften the tang?

Thank you for mentioning countersinking, I hadn't thought about that.

I might use epoxy, I just need to make sure it can take the 75 C/165 F baking in the oven.
 
Hi sogflash. I wouldn't use glue if I were you. After compressing the layers then heating, the layers will compress again so you don't want them glued so they won't recompress after the oven. You can soften the tip of the tang with a torch but all I did was grind the tang down to peening height with my grinder. I made sure I burned the end of the tang which made it easy to peen.

First, make sure the hole in your pommel piece VERY closely matches the part of the tang that sticks through it. Then, trim the tang so that only a few mm are protruding past the pommel. Now, begin to peen the tang: tap gently on the edges of the tang, slightly in an outward direction, all the way around. The idea is to "mushroom" the end of the tang, not to beat on it in the middle.

How much do the layers compress after being in the oven?

Should I be peening the tang, then heat the handle, and lastly press the brass piece down for a last peening?

I must have gone trough the guide a little to fast the first time.

how much will compress is depending from material(from 1-2 to 5 or more layers)
simple vise like above can help,or just use woodworking clamp,heat,re-tighten from time to time,then peen the tang.
 
leave birch bark under pressure couple hours,then re-tighten top fly nuts,repeat couple times and it should be OK.
