FA: Biax Power Scraper

Biax 7ELM power scraper on ebay.

Ned Simmons

The same motion like a hand scraper does. Don't know of this model, but some have adjustable stroke length and frequency (bet the description tells that).

New ones cost something in the 2k$ range.

Nick

That's it? Essentially a variable-pitch reciprocating saw?

With accomodations for side loading.

Wes

I think one of the reasons for the higher cost, would be the lower volume runs Biax makes as opposed to the millions of Sawzalls Milwaukee cranks out, for instance.

But as it has been said, the stroke of the Biax is adjustable with an allen key for long strokes for heavy metal removal to very short strokes for fine work. These adjustments are contained in the aluminum gearbox. The motor assembly & speed control seems to be a standard Bosch powertool item.

Tony

The length of the stroke is adjustable, as well as the speed. The length of the stroke goes from almost nothing to over half an inch.

You don't normally get any more side loading than you would with a sawsall. I would think, that if you had the time you could make a sawzall into a scraper of sorts. Making it adjustable stroke would be a project. I never looked to see exactly how they do the adjustment.

John

even if you left the stroke "as is", you would still need to incorporate a precise speed control, and need to modify the shoe and spindle of the sawzall to approximate the angle of the Biax and incorporate the rubber shock absorber, you'd end up with a clumsy scraper since the sawzall is much larger that the Biax, and the spade grip of the sawzall is not conducive to scraping.

Tony

Many tools have been based on the reciprocating saw...

I have a 200 dollar kant-twist clamp I made in class a lot of years ago. Qty one production with no tooling up. Dollar estimate based on time into making.

The manufacturer sells them for considerably less since they could justify tooling to lower the overall cost and spread it across many clamps.

After bandsawing out the pieces, I had a real appreciation on how much time and labor a punch press and die can save.

Wes

yeah that was demo-ed on Howard Stern show awhile ago.

I was ordering some spotting ink today and my local distributor for Dapra mentioned that the powerscraper went up another 250.00 dollars US recently.

Wes

Probably just a side effect of the Dollar going down...

Mine cost me £35 IIRC, but it wasn't very new.
