Title: QB79 hardware size.
Post by: Funhouse42 on July 01, 2016, 09:47:34 PM

So my QB79 project didn't go as well as I would have liked. I'll be posting about that later. With the tearing apart and  rebuilding, some of the screws are getting rounded out. I was wondering if there is a parts list that lists the sizes of the screws. Something that would make a trip to the hardware store easier.

I do have the exploded parts diagram, but it only gives you part numbers, not sizes.

Awesome. Thanks for the info. I managed to find most everything I needed. Just a couple that I couldn't find a match for. Had different threads than the original.

Just be careful with the length of the stock bolt.  A little too long (although it will not so good up nicely to the stock) can be long enough to jam the valve stem (which runs though the middle of the steel ring that the stock bolt screws into).  Had that happen with a flush HexHead bolt used in place of the factory "stud" and it took me a little while to figure out why it wouldn't shoot.
