Hi forum, 

I have been wanting to make a lot of mocs (especially gearboxes) that use knob wheels, and i dont have any. Are there any suggestions on normal bevel gears i could use instead of knob gears? Also, what can i use instead of the rotary catch? Its a bit expensive for my budget on bricklink, and i dont want to purchase them unless i really have to. Thanks for your help.

I think you can also find them on shop.LEGO.com under the Pick A Brick section. Free shipping from LEGO for orders above a certain amount and VIP points.

For the gear boxes, you'll have to determine if the knob gears were used because of their strength.  Some Technic bevel gears can strip easily if too much torque is applied. They may not be an ideal substitute.

Im not a fan of buy parts from lego becuase their shipping is too much ( i dont want to sped $35 at a time). I like to buy used parts from bricklink. Anyway, most gearboxes use the knob gears as the sequential selector to shift, and in those cases i can use bevel gears.

In stead of the rotary catch system, use it's predesessor. Like on the old set 8466, which can be downloaded from Lego: https://www.lego.com/en-us/service/buildinginstructions/search?q=8466

Well, no, i need a rotary catch, not the predecessor. I have those but its so much more bulkier to use instead of the rotary catch, i guess il just buy them.
