everything u mentioned (chin, dips and knee raise) can be done on a power rack with attachments. I do fabricate and design power rack and training equipments (prowler, farmer's walk bar handle,etc) based on demand.

Some finished product

Heavy Duty Range Power Rack - 11 gauge steel + stainless steel





It was for two separate private home gyms

w/ the dip attachment



let me know if u are interested as I can reduce the size of the steel bar to a little to cut cost.
