The Lumberjack - a deadlift jack made from lumber


I made a deadlift jack out of lumber. It’s called The Lumberjack. I wanted to design a deadlift jack made from wood that didn’t require using a jigsaw to make. This is what I came up with. If you like the idea of having a deadlift jack but don’t want to make one, Rogue Fitness and Titan Fitness both have inventory available to purchase.

Cost of materials will vary based on fluctuating lumber prices and your location. This project only took a couple of hours and the materials were relatively inexpensive. There are lots of options on what tools and materials can be used to make this, here’s what I used:

Glowforge 1/4" draftboard 12" x 20" 1/8" baltic birch plywood

saw 4

Almost everything was cut with my mitre saw and all the angles are pretty basic.

table saw

I did use my table saw for two cuts. It was the safest way to cut down the width of the 2x4.

It’s hard to give you exact measurements for these smaller pieces because this dimensional lumber can vary a little bit. You may have to modify your pieces to fit. The goal is to have everything fit pretty snug. 

assemble!

To assemble, I use lots of wood glue, screws, and a couple bolts.  This deadlift jack is going to be supporting a lot of weight. I want to make sure it can handle it. I always drill pilot holes before putting in screws. It helps to prevent the wood from splitting and makes the screws go in easier. 

three's a crowd

I add a third screw into the dowel from the backside. I don’t want this thing going anywhere.

top screw

I add a healthy amount of wood glue before laying the 2x6 piece over the top and fastening it down. 

The final step in assembly is drilling two holes for the bolts. These are both going through the 2x4. 

Sandy

I go over the whole thing with a sander and 220 grit sandpaper to smooth out any rough edges and get rid of the markings from the lumber yard. 

don't bolt

With the holes pre-drilled, the bolts go in easy. However, I sorta jumped the gun on putting these in. You’ll see what I mean later.

stainy stain

The stain I chose for this is called Early American. It’s a medium brown that makes the pine look a little more like the color of cedar. I chose this color to the fit the rustic vibe of this project. Each piece of wood accepts stain differently, so i am getting slight color variations. I’m okay with everything not matching because this thing is rugged and tough. 

Earlier in the day I posted a picture on Instagram of my prototype and asked for help naming it. I got so many great suggestions, but Lumberjack takes the cake.

glowforge

I use my Glowforge 3D Laser Printer to make the nameplate that I will attach to the side. 

it's not flat

Once it is cut out, I realize it needs a flat surface to sit on. 

insets

I remove the bolts and use my drill press and a 1 inch forstner bit to create insets so the bolts are flush when they go back in. 

spray paint name plate

I spray paint the nameplate black. 

pop

I didn’t get footage of it, but I ended up cutting a thin piece of birch plywood to go behind the nameplate and make the lettering pop. I use four screws and washers to attach the nameplate and we’re good to go!

testing it out
testing it out!

I tested it out quite a bit and it’s holding up like a champ. I suspect it can hold way more than I can deadlift. 

lumberjack!
