Default Fan

A friend of mine had his exhaust fan for his boiler in his garage brake and he couldn't find a replacement wheel for it and a new fan and housing was at least a week out. So I made the mistake of saying that I could probably fix it for him. four hours later I was done. The old hub that was crimped in had riped out so I had to put the fan blade in the four jaw chuck and used the old hack saw blade trick to indicate it and bore the hole out bigger then made a new hub with a shoulder cut in the fit the new bore leaving the the back (less than 1/16" thick) large enough to reach the formed hub on the blade and welded with the tig. My eyes aren't what they used to be but I made it. Now the blade runs true and is better than new. I will need a favor from him some day, things have a way of working out. This isn't much of post but maybe it will help someone some day.

I clamped a hacksaw blade under the tool post holder and bent it up so it rode on the fan blades then set up the indicator so it rode on the blade instead of getting caught in the blades when rotated.

Nice job digr, as usual. I'm sure your friend appreciates your help and you are right. What goes around, comes around. BTW, I thought I was the only one who still has a weldor's finger.

Yep, I made two different sizes after seeing that post. The smaller of the two sees more use because of the limited size of my welding table. The other was made to the posted dimensions and works much better when there is room to use it.

Here is a link to the finger. The X looking thing is what I used to use for drilling shaft before I made this, now I use it for center punching shafts.
