When a client commissioned me to repurpose a treadle sewing machine drawer set, I knew I had to do something special. I thought it would be inventive to find a way to use the cast iron structure as the framework for the cabinets, and this upcycled cast iron apothecary cabinet was born! As an added bonus, I managed to use almost all of the rest of the original treadle in other upcycled furniture that I made. Waste not, want not. If you’d like to see just how I did it, scroll down and follow my step-by-step guide.

Create Screw Holes on the Outside of the Legs

Create Screw Holes


The first thing I needed to do was countersink the outside of the cast iron bracket. Originally the shelves were mounted on the other side of the brackets, but because I wanted to mount them on the other side, I needed to create screw holes on the other side. 

Cut the Cast Iron

Cut the Cast Iron


The drawers only came up about ¾ of the way on the cast iron brackets, so I needed to shorten them a bit. I inserted all the drawers and checked with a level to see where exactly I wanted to cut the cast iron. 

Cut with an Angle Grinder

In the end, I cut just above the word “DOMESTIC” that was in the cast iron. This worked out well as I wanted to use that part in another project. I did a rough cut first with an angle grinder, knowing that later I would have to do a more precise cut.

Level

I put the shelves back on to find the right spot to cut the top so that it would line up perfectly. I wanted the top to sit nicely without leaving too much room between it and the drawer below it, but also leaving enough room for the drawer to slide in and out comfortably. 

Mark

Once I had determined the proper height, I measured it on each bracket and marked it with a silver sharpie. Silver sharpies show up beautifully on anything that is black.

Cut with a Disc Grinder

Then I simply took the brackets over to the disc grinder and ground up to the silver line, making sure that they all were even.

Weld Tabs On

Grind Off Paint


I ground off a bit of the black paint so that I could weld tabs onto the brackets to support the top of the cabinet. I just used a few square nuts that I had. 

Clean up the Tabs

I cleaned the tabs up a bit with a disc grinder to make sure that they would take the weld properly.

Weld

Then I welded them onto the brackets. At first I tacked them on, but later came back and put a larger weld on them to make sure that they welded properly to the cast iron.

Remove Sharp Edges

Once they were attached, I cleaned them up a bit again to get rid of any sharp edges that might rub against the shelves.

Reinforce the Bottom

Add Screw Holes


I needed to reinforce the bottom of the cabinet to ensure that the two sides wouldn’t start spreading apart. I started by drilling two holes in each of the bottom shelves that held the drawers. 

Run Countersinks

I needed to run a few countersinks so that the screws would sit flush and wouldn’t stop the wooden drawer from sliding out smoothly.

Attach with a Wood Scrap

Using a wood scrap from the treadle machine, I cut a notch to make room for the ribs on the shelfs.

Attach with Original Screws

Then I installed them using original screws from the treadle machine. I try to do this whenever possible, just because something is old doesn’t mean that there is something wrong with it.

Create the Top of the Cabinet

Create the Top of the Cabinet


The client wanted me to use the original wooden tabletop of the treadle machine, and in order to do so I had to be a little creative. There were four nice looking corners on the wood, so I decided to just use those. In order to do this I had to cut the piece of wood into a few pieces to isolate the corners.

Use a Biscuit Joiner

Then I used a biscuit joiner to connect them. This is a nice way to make the pieces fit snugly. 

Add Pockethole Screws

I also used pockethole screws on the bottom to make sure that they were extra secure. 

Seal

I added a light coat of sealant to the top and it was time to assemble!

Attach the Top

Measure


I lay the top I had created on top of the cabinet to check that the overhang was even on each side.

Mark for Screws

Then I marked where I wanted to install the screws with a pencil.


Screw in Place

In order to install the screws with ease, I flipped the cabinet over and screwed them in by hand. Don’t use any power tools as the force may crack the wood. 

Attach the Feet

Attach the Feet


I didn’t want the cast iron to scratch the floor it would be on so I added adjustable feet to each leg of the cabinet. This was also beneficial as one of the feet was slightly longer than the other one, and I was able to correct this by playing around with the length of the feet a bit. 

Upcycled Sewing Table

I put all the drawers back in and I was done! This project turned out great and I hope the client will love it too! How have you repurposed old pieces of furniture? Let me know in the comments down below!

    Wish you could build and sell these on Etsy or your own website! I’ve been wanting something similar in an upstanding vintage/retro card catalog five foot five drawer stand. Phenomenal work!

    I have neither the skills or equipment to do that with my old frame but I thoroughly enjoyed watching the video
