New Class 441 Progress

[kgg]

I have been slowly putting together my new 441 Class sewing machine. Only a couple of minor things left to do. Install the presser foot lift pedal, figure out how much I need to cut out of the table under the cylinder arm without weakening the table top too much, redneck oil bath, and mount my under the table spool holder for the top and bobbin threads as I hate those spool holders that are typically supplied with all the industrial sewing machines.

i) I chose to use a standard industrial sewing machine table 22" x 48" with a 3/4" table top and modify it to suit my needs. That saved me about $200 CAD. The table top had the standard belt slot and the three servo mounting holes already cut out.

ii) I placed the sewing machine about 1mm to the left of the belt slot cut and set it back 26mm from the white table top edge (ko4.jpg).

iii) I cut the top long end off the third K-leg and mounted it backwards so it would fit in front of the motor (ko7.jpg) then placed it so it was slightly off center of the sewing machines mounting base. The motor is a 800 watt brushless servo motor and came with a needle positioner which I am not installing.

iv) I bolted all three K-legs so their top cross braces were inline with the frond edge (ko7.jpg) of the table top. This provides better weight distribution and strength to the table. The machine weight, about 50 kg (110 lbs), is more towards the front edge of the table and directly over the third K-leg.

v) I also bolted the third K-leg to the foot pedal bracket to add extra strength to the frame (ko6.jpg).

So far I am pleased with how the machine is turning out.

Looks like a very solid setup, which you really need for these machines.

Thank you. I did try and tip it in all directions and it doesn't budge. Now if was Singer black, hum. Airbrush anyone?

Most 441 machines are mounted on an off the arm stand be a H legs or Weaver stand.  I prefer that set up up.  You want to hang anything off the arm to sew, you will find problems in your current set up.

We're awaiting the cutout under the cylinder arm. I believe that's the plan.

Yes, I think kgg is trying to figure out just how much he can remove before it collapses.

Yes, the plan is to make a cutout under the cylinder arm but I'm slow. I'll get to that part after I complete the "redneck" bathing process. The first bath, a mixture of synthetic oils, now is complete and the presser foot lift pedal has been installed. Once the synthetic oiling is finished and the machine is running properly the next step will to remove three of the four bolts from the base, remove the drive belt and swing the machine 180 degrees so I can do the cutout. I really don't want to remove the machine from the table, it's to hard on the old back.

Ha! I brought my 441 head into the house and up 15 narrow, steep steps to my upstairs sewing space. One - step - at - a - time.  I don't know how my heirs will get it back down ...

One of those stair lifts perhaps?  Look after your back, once its 'gone'...its gone. 

Thankfully I had my Father help me lift the head on the table at the time.

Hi @kgg , I would suggest dropping out the left leg and try and get something closer to the 3rd pic down on this page.http://www.cowboysew.com/heavy-sewing-machine-stand.htm

In this video I did awhile back shows what I think is a good reason to consider it all be it a different machine the same problem exists
