Rebuilding a class 4!

Recommended Posts

HEEEEELP! I just scored a class 4 machine plus the motor for $1000. It didn’t come with the stand but it does have the motor. I have a full woodshop at my house. I’d like to rebuild the base myself with gorgeous woods. Has anyone done this? Does anyone have a schematic of the class 4? Dimensions? I got the instructions but assembling this thing correctly was not part of it. Any help would be appreciated. Thank you

What are you actually wanting? Dimensions for the pedestal stand?

Did you get the speed reducer pulley & bracket?

Thanks.

I doubt building a pedestal-type stand out of timber would have the rigidity needed, class 4's are big and heavy! There shouldn't be any problems making a more conventional table out of wood. More info needed on exactly what you're trying to achieve.

Moved your post to Leather Sewing Machines.  This is where the machine guys hang out and you are more likely to get responses here.

I'm guessing you mean a Cobra class 4? If so, any of a number of people, including me, could give you the various dimensions of the pedestal stand. Mine isn't a Cobra, but I'd bet the stands are all close enough to the same.

@dikman may have a point about the rigidity. The base is steel plate and the healthy sized post is welded to it. There must be a lot of torque on that lower weld. You could end up with something closer to a carriage for civil war era artillery ... :)

But, if all you need is the  measurements of the stand, I'd go measure mine for you.

I am assuming you have a Cobra Class 4 machine. Are you planning on building a Juki style frame where the machine overhangs the end of basically a regular flat top table or a pedestal style stand? Keep in mind that the head of the Cobra Class 4 like all the Juki 441 clones are going to weight in around 120 lbs and they are all nose heavy meaning they always want to tip particularly in the nose downward direction. The Juki table style would give you better stability and probably be more suited to sewing in the sitting position. While the pedestal style stand would be more suited for sewing while standing. Before choosing the style consider things like are their pets / kids that could bang into the machine and tip it over.

If you chose to go with a pedestal stand you probably would be better off purchasing one from the Cobra people unless you are welder and can fabricate a really sturdy safe frame.

If you chose to go with the Juki style you can usually get a used frame from a industrial repair shop for a reasonably cheap price and then add a nice table top.
