Here is close up of a pit saw I came across...

too pitted - or not?


I have long lusted after such a toy, but I do want to use it.

If you know about such saws, would you say this is worth buying? or is it too pitted by rust ... ?

I've been putting saws better than this into the Art Saw pile. They are painted or Plasma Arc into designs. If you were to grind off all the rust, you wouldn't have a very thick saw.

Hello Gavin,

I've been lucky to come across two pit saws here in sth. Aust. both for about $40
which was a steal in both cases, only one had the tiller handle though.

They are a very rare type of saw to come across compared to all the cross cut saws
that are every where.

Both of my saws have seen a bit of work, but they have plenty of width left in them
to sharpen up.

Even though they and your blade has pitting, you can still obtain a reasonable tooth
profile after filling for the saws to function well.

I would suggest that you buy it providing the price is ok, does it have both the
tiller and box handles? If not, you could try to get the price down, there are plenty of
old catalogues about that you could use to see what shape the handles are,
it would just be a matter of finding a black smith for the tiller, and the use of a lathe for the box.

Good luck,

Regards

Graham.

Just throwing out an idea because one must be brave to learn, sometimes.

If Gavin sanded his saw down to 600 grit and if there were still pits on the sides of the saw, could he then use automotive bondo to fill in the pits? In a previous post somebody decried the problems of pits on the surface of a saw and I was thinking that bondo would be a good way to eliminate the pits.

Hi all,

With regard to pitting on saw blades, if it is on the sides it may mar the appearance and may cause the saw to drag somewhat in the kerf
which would be minimal to performance.

When the pitting is at the tooth line, where all the different angled surfaces are and depending upon how sever it is
it may affect the finished profile of some or all of the teeth to some degree, causing a drop in performance
because each tooth is not identical to the finished shape of its neighbour.

The degree of perform loss from pitted teeth will only be known if it is trialled and then compared to a saw that has no pitting.

I think to try and fill any pitting would be a waste of time and effort,

if it was an ideal world there would be no rust.

Regards

Graham.

Gavin, did you buy that saw?
If so, were you successful in getting it in working condition?

I agree with macg about rust pitting on the side vs at the tooth. Meaning I don't really care about the surface of the side of the saw, I'm more concerned with the teeth.
