Maybe you can but I wouldn't do it. The holes are not that big and once you unscrew the end bolts holding in the sandwich bar, there is not a lot of room in there. You are likely to push against a bolt and possibly ruin it. Also, there is a lot of lateral pressure on the punch and receiver. If you try to push with a bolt, you are focusing that pressure in a small area rather than using the surface area of the hammer to get it out. Also, I can't hold that jig, a bolt in the hole and the hammer at the same time. I was trying to be quiet when I filmed so if you can make noise, the punch will come out with a few good whacks against the top of it like I did in the video. Grease is your friend.
I think what Thewabbits referring to is that you are pushing against the cap screw heads in the jig. It will eventually damage the cap screw making it harder to remove the die bar after repeated use. His die bends a lot of flats. I see no issue with tapping it off with a mallet. Verses having to use vise grips to get the cap screws off after you mash them. It's all in the way you want to use your tool. No doubt both ways work.
Thanks for the demo. I'm happy to adjust my methods to the best practices. I have to bend the AMD-65 flat this weekend so I'll try it this way and film it.
Sure, I didn't film it. I have just seen it done a few times. I'm living vicariously through videos like yours, until I can justify the $. Can't wait for the next one. Keep up the good work.
I found another AK-74 flat to bend so I redid the flat bending video. I also bent the AMD-65 flat and editing that video too. Here's a look at the test fit after bending.
