Does anyone have one of these? I would like to have a back up. I am going to have to replace the bearings in this one (again) explanation is too lengthy so I won't go into any details. Also, if you look close you can see a crack on the top of the housing? & I was wondering if that is okay like that or could that be a problem?   |

I would drill a hole at the end of the crack to stop the crack growi sng and the fill the hole with epoxy containing steel.

Just take it down to a decent machine shop or welding place and have them weld it up. With some new bearings it should last another 20+ years. You can probably get it welded for under $40, check craigslist for welders who can Mig/Tig weld aluminum.
Good luck,
Tim

yes, I think new bearings and crack repair is the way to go

As I told Donnie on another forum, the crack may not go all the way through. It might be a surface stress crack caused by cooling too quickly after casting the part. I'd pull the bearings, clean the casting real good inside and out, and see if the crack extends all the way through before going to the expense of TIG welding. If the welder doesn't know what he's doing with aluminum castings, he could cause more harm than good. He may warp the part, making it useless. The part would first need to be cleaned of every bit of old grease and paint. Then it would have to be heated in a heat treating oven to just below melting point, and welded while hot. Back in the oven and drop the temp slowly over about 24 hours.

Yep, what Don said. Welding castings is tricky.

Dang Donnie, I was hoping your rig was an old 10 inch Beacon Star. Got a old rig sitting my shop with the entire arbor, bearing set up still intact after the power feed and such caught on fire and burnt up. I really miss that saw. It was twice the rig the new Covington is....Mel

You can probably get it welded for under $40, check craigslist for welders who can Mig/Tig weld aluminum. Good luck, Tim +1 to local TIG welder. Welding shops will often do a small job like this for a 12 pack of some ice cold beer. I recommend Sam Adams for this kind of work. It is also likely they will be able to press in the new bearings for you. For the same 12 pack. If you feel guilty, make it a bottle of nice whiskey. I recommend Maker's Mark for work like this. lol |

Ohhhhhhh Scott, you made me laugh with that one! Since this is mainly a fishing town & 99.9% of the people down here clueless when it comes to lapidary anything, I am going to send it to someone who will not only swap out the bearings for me but check the shaft & make sure the alignment is good by testing it on another 10" HP. Anyone around here would just go....................huh?
