    retrograde

    Hi
    Can anyone tell me can I swap my 9speed wheel for one with a 6 speed freewheel.
    Shifters are not a problem but I am concerned about chain, chain rings and Wheel dish.I was just going to swap the hubs till I realized one is 36 and the other is 32

    You will need a different hub to accept a freewheel so to go to a 6-speed freewheel you will probably be better off with a different wheel entirely. However, your 9-speed hub is a 130 mm OLD if it's on a road bike and 135 mm if it's an MTB and 6-speed freewheel hubs are almost all 126 mm. So to fit into your frame you will have to respace the 126 mm hub to 130 or 135 mm and redish the rim. Going from 126 to 130 mm can be done retaining the same axle but going to 135 will require a longer axle.

    Your 9-speed chain and cranks can be used with the 6-speed freewheel.

    Now, for the real question, why bother? What "improvement" will this give?

    I didn't want to use the 6spd originally. But I bought a wheel set and I intended to swap my original rear hub for the one in the new wheel.But now I realize my hub is 32 hole and the new wheel is 36 hole.So until I find a suitable hub I can afford ie dura ace or 600 will the 6 spd work well enough.I know it's dumb

    OK, now it's a bit clearer, you have and need to use the 6-speed wheel as a stop gap, right. OK, you could just install it as is in the frame and squeeze down on the qr or nuts to compress the frame, sort of cold setting in reverse.

    Better would be to respace the 6-speed wheel to 130 mm by adding 4 mm worth od spacer(s) to the non-drive side, recentering the axle and redishing the rim.

    If you tell us what's specifically wrong with the original 9 speed wheel, then that might open up some solutions.

    E.g. if your 32-hole original DA/600 hub has a bad freehub body, you could swap it most likely with the replacement freehub body on the 36-hole wheel hub of the same class, and you'd probably need just a 10mm allen wrench in addition to standard cone/crescent wrenches for axle work.

    Similarly, you could also swap cones or swap axles, etc.

    If you're rim is gone on the 32H original wheel, then you might think about just getting a new rim and re-lacing it. If you're saving up for a Dura Ace or 600Ultegra hub, you might spend around $25 and get a Tiagra or 2200/2300 freehub that works for you as a stop-gap. They make decent hub, that's if you don't mind the mis-match.

    But maybe I misunderstood your post.
    Yes, I can roll my own potsticker skins!

    A Phil wood freewheel hub is a great piece, one advantage to freehubs is relocating an axle cone
    to be close to the dropout.
    I found since Phil axles never bend, I used one on my loaded touring Bike for decades..
