I’ve been meaning to get my bandsaw up and working. All the bearings were going bad and some bozo long in the past decided to lose one of the eccentric bolts to adjust the bearing and replace it with the wrong size bolt too.
Now I don’t blame him for the wrong size bolt thing because the originals (only 2 left.) had 5/16 thread with a 10mm shoulder for the bearings... I wanted to believe the were m8 but no sir they are indeed 5/16-18.
So then come my realization that McMaster doesn’t carry what I need so I’ll just make some. So after a few weeks and me even cutting stock on my mill I’ve decided to start fixing it.
I got the 2 smallest screws made after a few trys. Kept messing up the bearing diameter.
Then I moved to the slightly longer screws. I decided to copy the ones that were in there but give them a 10mm shoulder. I did not realize that the thread were too long though so I made one and it didn’t fit the bearing so I made another and it fit perfectly I was like great I’ll make another and I got that going just to find out the darn thing has too long of threads. Now I could just cut off the threads and shorten it but what’s the fun in that?
Tomorrow I’ll get the correct bolts made and maybe try to tackle the eccentric bolt.
If anybody needs one of these oddball bolts for the same saw let me know I can send you what you need.
The bolts are made of 17-4 stainless 47hrc
I actually purchased a bar of 4140 to make them from but did not consider the fact that I did not have a bandsaw to cut the down small enough to get in my lathe.
I tried to make a video but it did not turn out well if there’s any interest I’ll try to take a better one tomorrow.
