Best steel epoxy?

Have about a 1" diameter pin that has worked loose and made the housing it set's in egg shaped. Want to install a new pin and drill and tap some holes in the housing and install two set screws 90 degree's apart to lock it in place. Just before installing the set screws I plan on filling the gap with a flowable steel epoxy. Once the pin is installed it will never be removed and if it doesn't work as planned the only option is to replace the housing. Long cure time is fine but it has to flow, so puddy is out of the question, it needs to be a little thinner than jb weld once it's mixed up. What product have you folks used in this situation. TIA Merle
 
I agree it is good if he can get to the back side and put a modeling clay dam behind and on the outside then fill from the top it will be fine. Jim
 
Check out Belzona as mentioned. I seen it used to build up shafts, it is so hard the machinist has to retool it. gobble
 
I use JB Weld and if you warm it up, you can pour it. I warm it on my coffee cup warmer using a metal lid to hold the JB Weld. It will cure a lot faster after it has been warmed. Not too hot, probably about 120 degrees. Also warm up the metal being repaired to room temperature or above.
 

You can mix a little acetone into the JB weld mix to make it thinner and pour real good. The acetone will dry out of the mixture and the JB weld will dry and cure like normal. I have used this method a few times with good results.
 
If your intention is to make a permanent repair, why not just braze the pin in place?

Devcon makes a decent steel-filled epoxy, but epoxy is not a good choice for anything that gets hot. You can also mix your own filler using epoxy resin and powdered steel, that way you can get it as thick or thin as you want.
 
I would go along with the Belzona I have seen it used here in the UK in a very similar situation to the problem described and it worked like magic. If you consult the Belzona rep for your area I am sure they will have a product to suit your application be aware though they are not cheap to buy.
 
What is this for?

Sounds like some kind of hinge point or for some part to be quickly removed with little effort.

if so, the attachment point and/or hinge point is designed for some very small movement that will erode and/or cause the epoxy to crack and fall out over time

Drilling out the hold to just enough to remove the egging or replacing the part will give you a better long term solution.

If it was a bolt and tightened sufficiently so that their isn't any movement then you stand a chance with epoxy
 
if you use JB weld use the slow cure and not the quick set--it has higher compressive and tension qualitys
