You always 'need' more tools
I wouldnt bother with pipe bender, cheap ones usually kink pipe unless its really thick walled ( ok for frame tube, probably)
I'd go with a larger drill press, floor mount with as many different speeds as possible and the best bearings you can get ( they all have some 'slop')
Get a Gas Mig, not the gasless type. Harbour Freight has a polisher grinder for around $70.00, less every few months when it goes on offer, just remove the grinding wheel from one end and fit another mop.
Get a good valve spring compressor and whatever flywheel/ generaor rotor pullers you need, three leg pullers are ok for gears but tend to destroy generator parts.
Check out Victor Machinery exchange in NY, they carry all sorts of interesing stuff you did'nt know you needed (until you do need it
) particularly 'odd' sized taps and dies ( 6.00x0.50mm etc)
