I blame Rob . Just when I posted in his 'DP Quest' thread about how much I like the Delta woodworking DP table design and how much I use it, it fails!
Here's the general design that allows the table to tilt forward and back. the second shot shows the minor fail on the left trunnion.
Here is the total fail of the right trunnion block.
Now before my dad starts telling you how I tend to tighten things like a gorilla [let's all remember he broke his banjo of his lathe ] despite my 5'-10" 175lb frame, let me show you the size of the handles they provide for torquing this thing down. The table is quite beefy at about 25lbs. The handles look and feel like they are designed to allow an easy tightening . . . maybe too easy.
You can see the design flaw. The locking block rides on a couple of "blades" that set in a couple of grooves in the trunnion. There is, however, no limiting mechanism designed into the casting which allows the resulting energy from the torque to focus at the bolt head.
This was one of maybe two redeeming characteristics of this DP. I don't know if parts are available but, I will try to get them and modify it to be less destruct prone if possible. Those of you with similar table designs, Delta or not, may want to take a look under the hood before things go south.
A few minutes later . . . .
Well, that figures:
I'll try elsewhere.
A few minutes later still . . . .
ereplacementparts usually has everything but . . .
I found them here. We'll see if they actually show up
