Thread: A tale of 2 saws

Paul,
If it were my saw I would likely have a go. Guess I'll have to see what crowie thinks.

Brett,
Those rasps do look user friendly. Ill send a PM. Got things on these next few days but expect to be back at it early next week.
Regards
John

That'll be fine John.

Hi crowie & john ...

I am interested in the crosscut saw info because I have this one ... (still covered in lacquer in this picture)





but I was forgetting that this is sitting on top of the laser printer ... as you do ...

Hope it helps,
Cheers,

Ooop ... one more thing ...
I had forgotten this ... I had a go at sharpening the lacquered saw previously ... https://www.woodworkforums.com/f152/s...5/#post1569372

After trying files, I found the angle grinder was a good "file"

Cheers,
Paul

As Donald Duck would say, "uck guck!", I've heard of carpenters referred to as wood butchers, but that's a bridge too far. I'm gonna tell IanW on you.

Paul,
The tyzack is the same tooth pattern as the one I am working on so a good pic of what I want to end up with.
That one of yours with the M tooth looks like it would be easier to work on. Looking at the pic it looks like the teeth are set in pairs. The set on mine is tooth by tooth. I dont know if that is as it should be or just what a past owner did to it.
The old saw manual was a good read and has given me some more info to ponder.
I may take your advice about using a grinder for establishing the basic shape then finish with files. It was a fair bit of file work just to joint it so fileing out those raker gullets would be a chore. Ah well I picked the job so cant complain now.
Regards
John

Well, I'll wait & see the result before getting too upset, Brett. Bloke I knew used to cut keyways in shafting with a hand-held grinder, & did a damn good job of it, too! Said bloke was a pretty amazing character, who built all his own lathes back in the days before w'working became such a popular hobby. He levelled the ways with a scraper made from an old wear-strip off a grader blade. They looked like the real deal, & worked well, too. His simple method for making cam-operated banjos was ingenious - been meaning to make myself a couple based on his, for quite a while.

I remember dad having saws re-gulleted in the 50's, but they were 'sent out' for that job, so I never saw it done. There would not have been any fancy machinery up our way, I'm sure, but there were still a lot of x-cut saws in use at the time, so obviously someone local was set up for the job. I can envisage a simple jig to hold the saw at each step as you feed it into a suitably-shaped grinding wheel - move it a notch, lock, repeat, etc. I've shaped a lot of saw plate on high-speed grinders, & the heat dissipates so quickly from the thin plate, it won't do any damage. For thicker plate on the big saws, a bit of care would be prudent - take light cuts & keep that wheel clean...

Cheers,

Saw gummers!

Some were a punch cutter like the ones used to make the saw in the first place, but it was a relatively small lever operated tool. You would put it on a bench or a stump and repunch each gullet. There were hand cranked grinder gummers but I think they were mostly used on circular saws.

Here's one that used cutting wheels.

Here's an ad. LINK

I'm sure Paul will come up with more!

Toby

Nope, I think you've covered it

But I did pull this out of the Lumberman's Handbook link ...

It looks like all three teeth get a bevelled point.
I was thinking maybe the vertical sides facing the gullets might be filed flat across like a riptooth/raker but apparently not.

Thanks everyone for all the advice and links. A lot to read and a big learning curve. Going by the remains of the gullets and 3 teeth between it would have been the Great Americian tooth pattern to start with. That said to get back to that pattern it looks like I have to file the teeth all the way off and start again as the gullet sides are strait. I got about an hour in the shed today and made a metal fitting out of a 12mm bolt for the front handle. I still have to turn up the wood bit. Ill post picks next week when I get back to it. I also marked in some ink marker line 2cm back from the jointed teeth to see where the gullet bottoms will be. Looks to be loosing a lot of metal. Will be even more when the teeth are all jointed off and I have to go still deeper. Anyhow Ill think about it as I try and catch a fish over the weekend.

bugger.

I didn't see the thread on the Blue Mountains GTG, of I would have come....I'm fiddling with saws at the moment, so it would have been doubly as good.
I have been scanning saw handles at officeworks onto clear plastic as a way of working out how to enlarge them for my larger than usual hands (I don't think its as simple as enlarging all dimensions, and am struggling with finding a comfortable grip). A chat with like minded people would have been ideal. next time perhaps.

Punch cutter.
