Thread: Cast iron table repair

Thanks for posting that Ken, its something I'll be doing a bit of later this year. I do hope his table doesn't warp after skimming 0.1" off only one side

Greg,
You missed a 0. 0.010"
Where did he say "Off one side only"?
Am I missing something again?

Stuart

Ahh! That makes more sense. And as to the one side only...I just assumed since the bottom would have the cross way dovetails etc

GQ

And on edit, I guess even if it did warp a bit it would not be that big of a deal since he could just scrape it flat again as he obviously has some talent in that area. It wouldn't twist into a potato chip.

So how did the damaged 2 slot table grow an extra slot?

Oh ok I see now Greg, I thought good cast was pretty good for that sort of thing. Of course "good" is a matter of opinion
That brings up a question I have, but I'll ask that in the scraping thread I think.

BT, what makes you say it only has two slots?

Stuart

I saw that earlier today and asked if he had a close up photo of the repair..
What a great job

Dave

I think now that I have f....d up. The clamps on the left hand side in the penultimate photo are tee bolted into a tee slot and not outboard of the table as my poor eyesight had led me to believe.

I've heard of JB weld, but never seen it, but I was under the impression it's some kind of metal filled epoxy for "cosmetic" repair, I would have thought a T slot repair would require a more robust fix.

I had some years ago and it was like a glue. Most people that talk about using it, usually talk of adding cast iron dust to it from what I have seen.

Dave

Ray, I thought that too, but he's only working on the top 0.062" which should be OK I guess. I have one table with damage all the way through the flank of a tee slot in one location. That repair will need to be more robust/ugly than epoxy.

I've used Devcon steel filled epoxy since the early seventies. A robust filler for when plastic body filler is not up to the task.

He has just posted a few close up shots of the repair.

You are correct, there won't be any load on the JB weld, the only force acting on the JB weld join will be compression when you tighten the clamps, and assuming there is enough of the depth of the slot remaining it should be fine.

What a clever repair, I would not have thought of that...I am a member over there but never seem to visit as often as I should.
Thanks for posting.
