Default Flywheels

I have an Alamo 1-1/2 HP. The flywheels are in nice shape and the outer rim has never been painted. I would like to clean them up and make them 'shine". It is winter here in Pa and I have lots of time Outside of taking them off and taking them to someone to put on a lathe, I would appreciate any suggestions for cleaning them and getting rid of the mild surface abrasion, etc. Thanks for your thoughts and suggestions. Rich

Either do it by hand with a sanding block and/or scotch bright.
Or disconnect the connecting rod and belt it up to an electric motor.

Flap disc on a 4inch grinder works well for taking off the rust and getting rid of the pits.

I would (very carefully) use some emery cloth in your hand while it is running. You can start with rougher and go down to finer cloth. You could easily lose body parts if you get tired and slip while doing this, but it will work very well. The emery cloth is liable to get pretty hot so be careful. I was wondering if a good grade of car wax would keep the shine on better than oil? I dunno. Kevin

Well if the engine is fastened down Solid I have used a Disc sander or a flap wheel on a small disc grinder. Just start the engine and apply the sander to the flywheel but.... BE Carefull . Also if the pits are really bad you could mount the cross slide from your lathe and take a thin cut off the outside while turning the engine slow with a motor.

I machined the collars on my Sawmill in this manner setting up things with a dial indicator. Now they run true with the recommended .002 to .003 taper. I had about every big C clamp I had used up when I did this.

If not pitted badly I'd use a belt sander with engine running.

To get the flywheel on my Maytag shiney, all I do is get some liquid cleaner on a rag and rub it against the flywheel CAREFULLY!. If you watch out, it should be okay to do. For some bigger engines, steel wool sould work well . By the way, would you have any information on Alamos built for Baker Hamilton & Pacific Co.? Thanks.

Rich, the methods these guys described have worked well for me. I use a electric motor for turning so that I can cover everything. Direct the side grinder/sander to blow away from the engine. A fan helps.

The dust from sanding/grinding is bad news for bearings and cylinders

I use Harbor Freight Tools sanding sponges which come in 10 packs and are very reasonable especially when they are on sale. I just run the engine and sand away any rust, paint and scratches. Then I use some oil on a rag to keep down the rust. Cast iron dosn't rust very much so I just re-sand and oil each time I show the engine and each time it looks a little better than the time before. I try not to hold the sponge sanding block where any grit is likly to fall onto the bearings. At some point when the fine grade sanding sponges are too coarse I will probably find that fine wet and dry emery paper will do a better job for the final polishing of the surface.

I personally like the look of having not only the face of the flywheel shiny but also the 1/2 inch or so lip on each side if the flywheel which gives a nice look from a side view.

I have thought that I might try making an arm that would hold the sanding block in constant contact with the flywheel face and let the engine run for some time to see how smooth I could get it. I haven't run out of other more pressing projects, so I haven't tried that yet.

Dick

Thanks everyone for all the great suggestions... will try them out. I don't have any bad pitting but they (flywheels) will look much better with a shine to them as they have never been painted. Rusty....I don't have any info on other Alamo engines.....mine is a 1920's model with an enclosed crankcase and I have been looking for any info plus decal info for it and it seems difficult to find. Have a great day everyone. Rich

Smile Re: Flywheels

I have used a belt sander while they engine was running.The engine was on skids and well anchored.I held the sander at about 3 o'clock and had my shop vac running below the sander collecting the rust and grit.I then finished
with hand pads and steel wool.Good luck and work safe !
