Air powered Draw Bolt

(1/8) > >>

Darren:
I can't find it now, but someone in the US mentioned they had built an air powered drawbolt device for their milling machine...

Would you please care to expand?

Ta... :thumbup:

I've seen several home-made versions.  They use an impact gun or ratchet.  Fabricate a bracket to mount it to the top of the mill attached to the drawbar.  Then it's a matter of figuring out how to operate the trigger and reverse.

Darren:
Thanks, I have seen a few Utube vids, I was just wondering if anyone can give first hand exp and some greater details... :thumbup:

I dont have any 1st hand experience, but I remember reading about powered drawbars on cnczone.com,

I'm sure that there's many other threads on there about powered drawbars, but my net connection is painfully slow at the moment (I'm not at home so am using a mobile internet dongle thingy), do a search on there and that'll turn up more info.

Hi Darren,

Done a little searching for you, and have come up with these two.

The second one might give you a better insight.
