POTD- PROJECT OF THE DAY: What Did You Make In Your Shop Today?

Finished stripping down my newly acquired 1957 Singer 99k:

Was a bit of a challenge as it doesn't quite come apart like most other vintage machines I've worked on. This one has a lot more press in and "one way installed" parts. Add to that there are some parts that are fairly weak cast iron bits that can't be forced or pressed/hammered on and it tool a few days to figure it out.

But it's stripped, except for a few little data and brand plates. I need my drive screw pliers to show up to get them off.

For now though, it's into the ultrasonic cleaner for a couple rounds of stripping off nearly 7 decades of dirt, oil and smoking tar.....

I bought the creme formula by two coats with a light 0000 steel wololing. Does the liquid work better?

I've done a few things with the liquid version. Every thing needs to be absolutely clean or results will be uneven. I used 2 coats with a light 0000 steel wooling between & after followed by some oil. Got nice black results. I don't know how durable it is (yet.)
 
I am balancing the drum of my Delta Drum Sander (woodworking). I got it used, and I don't know who balanced it, but it was shaking a bit.
I haven't gotten it all out yet. But using my cell phone in slo mo, and VLC I can watch frame by frame so I can see my reference mark on the shaft, and the dial indicator to see where it is out of balance. It's a game of vectors, since the vibration is slightly out of phase with the balance. I would have thought it close, but I'm learning.
 
Get a hose clamp and place it around the hub or od.

If possible, add 2 identical ones 180 degrees apart.

The screw part now becomes a weight.

2 at 180 cancel each other.

Shifting them closer makes an adjustable amount of weight in a variable position.

This allows you to determine the general location of where weight is needed to be added or removed.

Once this is determined they can be removed and weight adjusted.

Take it off and static balance it. Let gravity tell you where the heavy spot is. Then just add or remove weight until it stops in a different postion every time you spin it.

I static balance motorcycle wheels the same way all the time. Have yet to fond one that won’t balance on one or two tries.

Trying to do it dynamic without test equipment will end up driving you crazy
