This was the most massive project I have undertaken to date. It was a break away from furniture making into other areas of woodworking. I was asked to construct a 4 metre by 4 metre competition Olympic weightlifting platform for the Alberta Weightlifting Association. The association was looking for a less expensive platform (they can cost upwards of $20 000) that was more portable (the ones that are used in the Olympics are typically 3 sections at full length) so that it could be transported in a regular half ton truck. It was to be made of rock hard maple and be 3 inches thick. I have never ordered that amount of lumber before! As you can see in picture #2 it was about a lift and a half of 8/4 stock. The platform is constructed of 17 smaller slab sections where each section is constructed into a 3 inch thick butcher block bench top slab with the boards standing on edge. In order to bring the sections together into the full platform, holes were drilled into each board before they were glued up. The slabs are held together with threaded rod running through the platform into the opposite side of the center section. Picture #4 shows the slabs with the rod holes running through them. According to the rules of weightlifting, there had to be a 4 inch border around the entire platform, so I did that by carefully masking and scoring a line in the wood then staining the border on and then top coating the entire platform.

Here are some more pictures. Please feel free to comment and critique as usual

Another Alberta boy. This project looks like one massive undertaking. Very likely you can compete on the stage after the build, with all the wood you worked through I’d think you could press 500 lbs easily now. Next project a basket ball court floor?

It was a lot of heavy lifting! I think I want through like 12, 55 gallon drums worth of wood shavings coming off of my planer and jointer.

Wow awesome job, I never knew they were made of wood. I know weight lifters drop there weights. I guess the wood is strong enough to with stand the weight of hundreds of pounds. Thanks for posting.

Yup, they drop the weights. The plates are rubber and the weights bounce, but the wood is stable and strong enough to absorb and withstand it.

That is one of the coolest, wackiest, and most unique projects I have ever seen on here. A very interesting build. Congratulations on your persistence and hard work. I just made 15 cutting boards for christmas and got tired of my jointer, I can’t imagine how you felt! Well done and I hope you were able to bring in a solid profit (I shudder to think of the bill when you purchased all of that maple). Keep it up!

Hey Jeff! May I bother you to ask what type of wood finish you used? I have a mini one that I just built but I’m unsure of what to finish the wood with. I live in southern California and its going to be in my garage . I’ve heard anything from putting nothing on it , a 2-in-1 Polyurethane/Stain, sealer at the least or a penetrating oil varnish at best, preferably Waterlox? What might a professional like you suggest? Thanks!

The finish was a HUGE deal to the association! The feel of the platform under the feet is a major deal for a weightlifter. I left the slabs sanded to 120 grit out of my drum sander and this gave the wood a nice ‘tooth’ to it. It was grippy without being too grippy. When they came to test it out they loved the feel of the unfinished wood. Any film finish (Poly, laquer shellac etc) would definately detract from it, but they did want some moisture resistance. In the end we wound up using an exterior deck stain/protectant. It soaked into the wood nicely and should provide some moisture resistance while maintaining the feel of the platform

Jeff,

I just saw this.. It ain’t fine furniture, “but it sure is fine!” Impressive task, well done.
