Jackshaft?

>What is a jackshaft and where can I locate them? I have seen the reference to them in a few posts.

This is for a potential horizontal mortiser.

Thanks

>From what I know about jack shafts.... you make them from various components, including 1 steel rod, 2 pillow bearings, 2 sprockets,gears or pullies.

The jack shafts I built were for go carts and mini bike, but the principle is the same no matter what the application.

Instead of having the sprocket (or pully) on the engine (or motor) drive one chain (or belt) that connects directly to the sprocket (or pulley) on the wheel....

You have have the engine sprocket and chain drive a sprocket on and additional shaf located between the engine and the wheel. Then on that same shaft you have another sproeckt with another chain that goes to the wheel.

IF you have a larger drill press you can see this in action.... it's the middle idler pulley located in between the front and rear pullies in the drill press.

I looked for a picture that shows it better than I can describe it, but couldn't find a photo.

Happy Woodworking!

>Not sure how you want to fashion your horizontal mortiser. But I've built a couple in the past. If I had it to do over again I'd probably do a direct drive setup. If you go to Graingers newest catalog (#398) Pg. 98 has a bunch of adaptors you can stick on the end of a motor including a keyless chuck.

>You can buy shaft material with keyways or plain and mount it on pillow blocks which is essentially what a jackshaft is. www.mcmaster.com is a good source for parts and ideas on what's available. www.surpluscenter.com is good for parts also.
