New bowsaw

[Waldo]

G'day Bidgy,

Nice work.

I'll tell you a story. I was doing a bit of backyard maintanence which included getting the bowsaw out to hack back a Hibiscus, as I was doing so the blade jumped (as they do) and cut 3 deep cuts through my left thumb :eek: , one of which cut 1/3 of the way up my finger nail, didn't hurt at the time as all sharp cuts don't but afterwards!

The blood ran forth, and I had to suck in the language as I had 2 little nephews helping at the time.

Coulda been worse, don't you have a chainsaw?

G'day Bodgy,

Nah, don't have much of a call for one. A chainsaw'd be nice but there's others things on the list that are ahead of it.

As there is movement you can't fix this middle bar in place. Neither can you use traditional joinery as cutting out a mortice (or whatever) will cause the two end vertical members to loose strength and hence probably snap, or at least bend too much to be effective, when tensioned up.

Hi Bodgy

I am not with you here. Every bowsaw I know, including those I have made, use a M&T joint for the cross piece. It is a loose joint, and the two ends pivot around this.

Here you can see the centre mortices:

I also used a bandsaw blade (6 tpi). It works OK on dovetails. My next will for re-sawing and use a cut down mitre saw blade.

Derek that's one gorgeous looking saw.

Now you guys have got me really excited so I gotta make one too. Is there anyone in the Perth area that can sell/donate/trade a busted band saw blade?

Thanks

[derekcohen]

Sure Bob, got plenty. Come over and get some. I'm in Rossmoyne. Where abouts are you?

Regards

What a beautiful saw, it puts the rest of us to shame, however.........

In the design you have obviously compensated for the loose tenon, by doubling the wood depth at the middle. My point was that without this compensation a mortice would weaken the piece.

That is a beautiful bowsaw Derek! Is it recent?

Cheers,

Nice saw Bodgy.

I don't want to be picky guys but I was always led to believe that dressmakers use cm for units of measurement, woodworkers use mm.

Keith, you may be right, my last dress, a sexy little black cocktail number, was measured in cm.

Seriously, I find it all too confusing metric v imperial etc, particularly when you get to screw threads. Converting fractions of inches to metric is particularly tiresome, as the verniers etc give a decimal value to inches, ie 0.5" rather than 1/2". Try converting 5/64" to metric
