Nice one Jon33! Would be very helpful if you could do that measurement and let me know what EZ curl you have (guess it's a 5 footer)?
Are the dip station bars are comfortable like that? Guess some foam or something could be put on them if not?
edit: did you have to buy an extra dip attachment so that there's one for each thigh or does it come with two?
Off to the gym (garage) now so I'll check with the EZ curl, it's actually just the one off powerhouse (http://www.powerhouse-fitness.co.uk/bodymax-chrome-olympic-ez-curl-bar.php) not sure about it's size.
I don't have any problems with the dip bars like that. The bench you've linked is essentially the same but I've taken the leg bit off the end, I did pull the foam bits off that once and put them on the dip bars when doing lat pull downs but I've not bothered since.
For the dip attachment it comes with two bars that just slide into holes on the catchers. There are two holes on either side but if you just put them both in the closest to the pull down kit it works fine (I'll get a pic for you)
