Biax/Bunax making group project
As suggested, I decided to start a Thread relating to the group project of making a Biax type powwer scraper.
I'm not really sure how this group project will progress or what direction it will take but I'm happy for people to provide their own expertise based on their experience of making their own. Also a place for people to express their interest in making one.
See how it does...

I am interested two and have no experience.
I think the first step so everyone is on the same page is to outline some basic parameters.
These could be along the lines of power or air operation, strokes per minute, length of stroke and such.

I would be happy to assist in making some parts. On the CNC lathe if needed. I don't need one as Ive got a biax. I do need to make blades one day.

I'll be in
In terms of power source - I think 240v electric is the most practical.
Everyone has a power point (not everyone has a decent compressor to run pneumatic tools), and you can use it all day without running out of battery etc.
Slap me around the head if I'm overstepping my station - but thought it would be good to get these useful posts from the Biax Info thread to save those members re-posting.

These Ozito recip saws might be a good candidate:
$99 retail at Bunnings - Likely we'd get a better price if we bought quantity.

I had my eye on one of these https://www.ebay.com.au/itm/Cordless...154756-20017-0 purely for the ergonomics, a leather hand strap could be fitted and it might be comfortable to hold and use two handed, Maybe there’s something similar out there that’s 240v and a more trustworthy brand.
I do kinda like the idea of an 18v unit but that can by tried later down the track

Ive had a look on both eBay and gumtree for S/H reciprocating saws.
I do like the look of the Makita JR3050T 240V saw. The parts diagram indicates it uses a Scottish yoke design so is suitable. These can be found S/H for around $100 or so.
I'm not sure how we go forward with this project, whether we source our own S/H or all buy the same one brand new...
Edit: rightly or wrongly, I was thinking a 240V corded would be better purely because they may be heavier.

Looks like Makita has replaced the JR3050T for the identical looking M4501KB - so much for Makita not changing their models.....
However, the new version is only $140 new from CL Tools in Brisbane https://www.cltoolcentre.com.au/maki...cipro-saw.html
Maybe that's a candidate....
I did contemplate the idea of a cordless one too. However, unless someone already has the batteries for other tools, then the batteries are expensive and you would need two and a charger (to charge the 1st one while you are using the second one). They would run for quite a long time, as they won't be stressed anything like sawing.... But I agree with Simon, the extra weight of a 240V one would help, as would the variable speed.Cheers, Joe

I think we can get hold of lots of cheap reciprocating saws - cheap brands, used ones, old stock etc. But my feeling is that going that route for a group build will lead to tears, since we are wiping the warranty on day 1.....
Sticking to a reputable brand like Makita is probably safer.Cheers, Joe

Assuming they haven't changed their mechanism design, thats just an updated model of the one Bob Ward posted in the Biax Info thread - that he won at a scraping class.
I'm picking if it worked well enough to be worthy of giving away in that environment, then its going to work for my purposes.
Any photos of the guts Eskimo?

Good point Joe. I guess its one thing to put a few hours into modifying a cheap one for yourself, but to do a whole lot and then find they all failed due to poor material would suck!
That genuine Makita M4501KB for $140 is pretty attractive.
Here's the parts breakdown if anyone can comment on its suitability: https://www.gettoolsdirect.com.au/sp...ating-saw.html
Edit: the only difference I can see between the KB and the $10 cheaper KG model is the KB has a "Dust and drip-proof design motor and gearing are sealed for protection against dust and water ingress"
Would seem like $10 well spent...

I have converted one of these Ozitos to a power scraper. An Oziax perhaps...
I chose this model due to price and variable speed.
It does have a balance weight which some recip saws don't.
I modified it for shorter stroke, about 8mm I think.
I originally planned to make it variable stroke by milling a dovetail or T slot as some others have done. However the relevant piece material is quite hard and I destroyed a HSS end mill. My dodgy mill is not up to carbide milling in hard material and I don't have carbide dovetail or T slot cutters. So ended up just using a carbide drill to put a new hole for the pin that effects the stroke.
I have not used it a great deal as yet.
Will did up some pictures in next few days.
