With help from some of the pictures on your site i was able to build a pull up bar and dip station.
Build outdoor pull up bar.
Outdoor pull up bars have become increasingly popular with the recent explosion in popularity of crossfit.
Bar only you purchase a straight pull bar with bolt holes and bolts.
Expand your pull up bar as needed for other exercises.
And another example of an outdoor pull up bar combined with horizontal bars installed by mike westhead how about this setup created for his son by bill kanter.
You build them the same way as the outdoor pull up bar connecting the bars to the original posts and 2 more 5 ft 1 5 m high posts.
They are available to be purchased in a number of options depending on your budget and preference as follows.
For example build a pair of parallel bars for dipping exercises.
