Screw splitter idea?

[djbobbins]

I was just thinking about options for a small screw splitter.

 

Impact wrenches are coming in offer in one of the German discount supermarkets in the next few days IIRC; would it be possible to fit one with a splitter cone?

All things are possible and its a novel idea but is it a good one??????

There'd need to be some kind of frame to hold the wrench in (that's not a problem to knock together out of strong ply or as a practice exercise for me in welding) but I just don't know if an electric impact wrench would have enough torque?

 

Mind you, I also hadn't realised how much a cone is to buy!

Is torque your only consideration? What about power supply, duty cycle stuff like that?

I agree, it is a novel idea and it would be interesting to hear the result.

 

The impact wrenches I've used in the past (doing garage work) haven't tended to wrip my arm over.... especially when compared to using a clutchless SDS drill (which have a history of keeping NHS A&E busy).

 

My thoughts are that having bags of torque may not be such an important element because the constant hammering may be enough to get the cone moving.

 

I guess it would work up to a certain diameter; but the maximum diameter it could cope with is anyone's guess.

 

cheers, steve

Even the biggest (top of the range) mains powered units probably wont have the torque for anything tougher than sycamore and since the design purpose is to occasionally spin a hand full of fasteners off, the chance of it having a useable duty cycle is minimal

The more I think about it, the more I think the angular forces from the tip of the cone would muller the motor bearings on the wrench.

Im sure you could pick up an old core drill that would some of the vintage ones have some serious torque

But if your going this far im sure ebay would yield a large electric motor with buckets of torque
