Thread: Another Doh moment

I was wondering about how you hold it ... given where the tape is.

I've seen seen Frank Krausz doing a straight push-pull along the axis of the saw, but that is where the blade is on the outer edge.

But a different grip here at 5:20 ... Vidéo Ina - L'ébénisterie, vidéo L'ébénisterie, vidéo Economie et société Education et enseignement - Archives vidéos Economie et société Education et enseignement : Ina.fr

Hmmm ... I thought this one was like yours but the blade is on the outer edge again ... do you use a two-handed grip? I know that using a western handsaw ripping speeds along when you can use a two-handed grip.

Hi paul

I hold the saw with both hands at one end and use the saw sitting down on the timber which in turn is sitting on my saw bench. The motion is a bit like pulling an oar and you use your big back muscles more than your arm muscles.

This is a link to show how the saw is made. And here's a link to a better description on how it can be used to resaw timber .

Hi jeremy

what TPI are you using in that saw?

Cool links Paul. That crazy router at the end of the first vid made my fingers feel weird.

The blade is 4 tpi. It is one of the ECE blades available from My Tool Store - it is said to cut both on the push and on the pull because the teeth are sharpened on both sides and have the same rake on both sides.

By the way, I finished the cut last night. The total time for the cut was about one hour (broken into a number of 5-10 minute sessions).

Hmm, i see you're using an ECE 4 tpi push-pull? That sounds like what they call a schittersaege, which is normally a rough docking blade for lumber and firewood. A schlitzsaege/spannsaege, with push to cut set up is what they typically propose for ripping. But hey, job's done

Jeremy, have a squiz at Lee Valley, they have some excellent tapes that are padded and bulky, a bit like a bandage.

How fast is the frame saw compared to a say 4-6 TPI common ripsaw?. I've seen video of Roy Underhill using the frame saws and he seemed to get very decent results.

Jeremy, that saw seems like awfully hard yakka!
I recently ripped a Bluegum slab to get a straight edge. It was more like 55mm thick but about 400mm shorter. I seem to recall my trusty S&J 5 pointer, got through it in around 10 minutes - I couldn't have lasted any longer than that at my stage of decrepitude....

Cheers,

I was wondering about the tooth shape.

Do they come to a point left and right looking along the length of the saw - which would be a crosscut-ish tooth shape, or - again looking along the saw - do the tops come to a small flat like the end of a chisel rather than the top of a pyramid? (which would be like a ripsaw tooth shape)

A close-up photo of the teeth would be very interesting.

I have a D8 that starts 11tpi at the front and is 9tpi at the rear that seems very sharp to me ... not through my efforts I might add ... and I think it would be cutting 19mm(3/4") jarrah at at least 1cm per stroke. That would mean 200 strokes per 2m if I could keep up the effort. And a courser tpi should run faster again I assume.

This is not to nag at you - I commend your efforts. I am starting to think/learn that when people had 'only' these tools to do their work with that they were capable of being pretty damn effective with them - and it is interesting to try to relearn/recapture that knowledge and ability.

I'll tyake a photo over the weekend, but I fear that the quality may not be great (I will haqve to use my phone). My recollection is that the teeth are filed rip and that there's not much set.

I reckon I made a mistake getting the two way teeth. I am thinking of gettting the 5 tpi blade which has almost no rake. I will then see whether the setup is more efficiient cutting on the push or the pull. I suspect that since the action is like rowing, a pull stroke may be the way to go.

Jeremy, i use a 5tpi ECE blade in my frame saw for ripping and it blazes through hardwood. One thing i noticed in the 2nd old french vid paul posted, is that the rip was performed with the saw vertical and the teeth facing away from the operator. i.e. you cut in the opposite direction to the way we would with an english pattern saw. But in any case i think you'll like the other blade better.
