Weld up all the seams on the bucket?
Original Message Dec 23, 2012 10:24 am

Hi all, first post.

I moved to a new house with a bigger driveway this year and decided that I needed a bigger snow blower. I picked up a Simplicity 860 and pulled it apart. The bucket has some rust on the bottom and I will need to cut out the area that the cutting edge bolts to and weld in new. Ill then have it blasted and repaint.

So while I have the welder running, I'm thinking of welding up all the seams on the bucket that are currently stitched in. Other than taking time, and the possibility of warping the metal if done incorrectly, is there any reason I should not do this?

I would agree with your Auto Body buddy. But if you don't seal the seam.
You will still get moisture in the joint and eventually rust will develop.
I have used weld through primer. The key to having it work well is to
spray the steel surfaces that will be over lapped.
You coat those surfaces before the steel is laid one piece on the other.
Your joint are already put together so you can't
spray the surfaces that really need it. They are covered up.
A little food for thought, while your having your beer.
Every vehicle on the road has one brand or another of
Seam Sealer being used to seal the joints of body and
roof panels. The stuff is specifically designed to be used
in exactly the type of application you would be using if for.
The blower housing itself may vibrate a lot.
But the actual joints/seams are not seeing much if any movement. If they were the housing would
start to break welds, or at the weld points the first season of use.
The problem with blower housings especially some of the newer ones.
Is that they are Powder coated. Powder coating has a hard time getting into the seams
and joints like a paint will. This problem is called the Faraday Cage effect.
Which keeps the powder from being able to get into corners and small tight places.
A paint coating is also thinnest on the sharp edge / corner of a surface.
That's why rounded corners well give a more longer lasting finish.
It allows the paint to maintain a more even mil thickness around a corner / edge.
Trying to keep paint on an un-rounded edge / corner of steel is like trying to keep paint on the edge of a knife blade.
You can see that in the photo of your housing (bottom center of the photo). There is a thin line of rust forming right on the edge of the steel
sheet that curves around the end plates. You for sure want to knock that edge off with a sander or grinder as part of your prep work.

I never thought about flushing out the salty snow, but I will be doing that from now on. My new house is on a cul-de-sac so I get an extra large pile at the EOD.

This rust appears to be from sitting in a pool of the salt water. I have an Ariens ST504 that I redid the bucket on 7 years ago. More often than not I fog it with some oil that I have laying around after I dry it out with a heater. It has very little rust on it.

I always start out clearing my EOD drive first. This is the most wet, salty, sand gritty snow that is bad for snowblowers with metal buckets and augers. After clearing EOD, I go over driveway and sidewalk with fresh snow to flush it out. It is quite effective technique and requires no additional effort. Before putting it away, I run the auger/impeller dry without feeding any snow. This will fling some stuff off the auger and impeller. If you're really OCD, you can use pressurized air to clean the entire snowblower off, be careful pointing it at fragile or sensitive seals. The other alternative is to use a leaf blower, which has much lower air velocity.

Salt and water by itself is fairly benign. Mixed together, they are a quite a corrosive force. Corrosion is a factor of time, concentration, and temperature of the salt water. If you have eliminate or reduce any one of these factors, it will reduce corrosion. You can't control temperature, but you can control time and concentration. The key is in drainage.

If you bring a snowblower back into a warm garage, the salt water will start eating away at the metal parts. I have a tracked snowblower so I can tip the bucket housing back and keep it off the floor and not have any pooling of water under it. It will stay tipped back and not go anywhere. If you have a wheeled model, you can put a 1x4 piece of wood, or non-metallic part under the skids to get the bucket and scraper off the ground. The snow will still melt, but at least the water will drain away, and not collect around the scraper and skid shoes. Drainange reduces the concentration and the time the salt water is contact with metal.
