I posted this picture of my vintage Singer 301 in my sewing desk and I had questions about the desk itself. So this post is to show it a bit more clearly. Here is a picture of the whole thing.
I purchased this steel case desk from Good Will a few years ago for $25. At the time, I didn’t yet have my long arm but I did a lot of machine quilting. I wanted a table with more room in front of the machine to support the weight of a large quilt. You can read the details of hubby’s modification of the desk here. And a modification to that here.
The opening that he cut in the desk was sized to fit my Bernina 1030 with the extension table on it. But it works so that I can use this for most of my machines. I sometimes place something under the machine to bring it up to the correct height. Like this.
When we redid the sewing room last year, the desk got a coat of spray paint. If you get a steel case like I did, beware that it is called steel case for a reason! Sparks flew when hubby cut the hole in the top with his skill saw!
Hope these pictures and the link help.

Great desk. I do love having my machine recessed. My husband modified an office table to recess my machine. It does make a difference – less back/arm aches!
I recently added a General Fireproofing tanker table to my sewing room. It has the rubber top and I will not be cutting into it but it weighs a ton and it’s not very big! I can barely budge it. I do like your white paint. It looks so clean and streamlined. I sew on two 301’s. I’m keeping one with a 1/4″ foot on it and the other for straight stitch. Love them and I may add a third just for the walking foot.
Great set up. The hubby built me an extension table that my machine sits in it and gives me a level set up for quilting
The desk conversion is sooooo awesome. I sew at the dining room table which is a little high but not too bad.
