I’m all for a good diy project, but I strongly suggest that you go with a factory made platform, especially for your first one. The tree suit platform is around $100 I think, and you’ll spend that making your own if budget is your only concern. If you don’t care about the price and just want a project then you’ll still have that question in your mind if it’s strong enough. I have heard of the lone wolf seat kit platforms failing. If you want the cheapest platform possible, I’d shop around on Craigslist or Facebook marketplace and you can find cheap cheap steel hang on stands. I made one from the seat of a steel hang on I got for $25 new and hunted it for a year. I upgraded to the ridge runner and love it. I made a video on my cheap one.
