fabricator part question

[Terry Oxandale]

I've seen this part before, but only once, and cannot remember what it was called, or where I found it.

The piece is a stub welded or fitted against the side of a tube that fits the OD curve of the tube, but has a flat end in which a bolthead can rest against. Basically, this would be used to provide appropriate support for a through-bolt, through tube, for bolting something to that tube without isolating all the bolt's compressive force on a very small portion of the OD curve of the tube.

If anybody can suggest the correct naming of this kind of part, then perhaps I can do a proper Google for it. Otherwise, I'm left which trying to make them myself.

Hi Terry

In the past, I have used a pipe saddle for that. McMaster Carr has some here.

Lately, I have been making my own. I take a rod, and drill my hole through. Then I set it up, and drill with a hole saw. And then finish off with a end mill. If you do two at a time, by drilling and milling in the middle, it doesn't really take that long. It seams to me they were called a tubing saddle fitting, but I can't come up with it doing a search.

Regards Brian

Thanks Brian. Yeah, your method is what I was going to use to make a couple of these if I cannot find them pre-machined.

Terry:
If you are thru bolting wouldn't it still crush the remaining part of the tube? We call something like that a swing tube, essentially go straight thru the tube with another thick wall tube that fits a bolt so that the original tube can swing around the bolt or simply be anchored. Sometimes I make these from solid rod by simply drilling out a piece on the lathe. You can look up some DOM tubing and probably find the sizes you need to do the job, and as far as OD & ID one can get a pretty close fit.
