What is a "Jump Saw"?

[Kev Godwin]

When I was traveling this last week I overheard 2 guys at a table next to me at lunch that were talking about getting a "Jump Saw" set up in their warehouse.

Can anyone chime in and tell what such an animal is? I'm pretty certain that is what they called it since they mentioned it a few times.

Thanks,
Kev

Hi Ken
I believe it is a cross cut saw used to cut long lumber to length.
Triggered by foot petal, the board is clamped and the saw blade comes up from under the piece to cut. It "jumps up through the wood".
A chop saw on steroids.

Yep. combined with a Tiger Stop, they work great for cutting up face frames and door parts. Bigger ones will do larger slab drawer fronts too. Whirlwind was by far the most popular around here, but I believe they went belly up. The only other brand I'd consider would be a Northfield. They great to use because your hands are free the entire time for loading unloading, and no where near the blade.

Thanks for the replies.
"Chop saw on steroids" - I guess so....
I really think I need one of those for my 200 sf shop!:rolleyes:
Thanks for the info.

Yup, my boss has a couple of Whirlwinds in the flooring department. Also known as an up cut saw. The blade literally 'Jumps' up in a sort of circular motion. Ours had a 24" blade that gives you something like a 16" cross cut. They sure do cut quick and clean, very square too if set up properly. Pneumatic hold downs, pneumatic actuated up cut driven by foot pedal, you need a lot of CFM's to push one, and most likely 3 phase for a real one. I used to chop the ends of 20,000LF of flooring per day. Like Karl said, two hands on the wood so it moves quickly with rollers involved, one foot on the pedal. Get your hand under it and it will cut that off too after the hold downs have crushed it.:eek:

I thought the term "jump saw" meant one of these.
