Two to go: The littlest
The baby. 9 7/32" dovetail with 20ppi (new sawplate). Handle is the unknown hardwood we cut down at the side of the house. It just reminds me of apple in it's appearance. I really hate little teeth, but I persevered.

And the biggest being the 5ppi rip saw. This was my old Warranted Superior 28" saw that I cut down a little. Gidgee handle and quite a bit of colour when caught at the right angle.

Just a few comments. I have to adjust most of the saw screws and as yet I have not filed any flush. I am hesitating with that as I don't see how I can do that without damaging the timber finish. The backs still have to be crimped up and I have not done that yet as I have to find some aluminium protectors for my engineers vice otherwise there will be irreparable damage to the brass backs which tend to mark if you look at them hard :( . I think I am starting to realise why steel was popular, with the American manufacturers at least.
The three crosscut saws I filed with angled teeth. This produces what we call sloped gullets. However the gullets are a consequence of this style of filing and not the object. We have discussed in the past that it increases the gullet size, but I am not so sure of that: The gullet may be indeed be apparently deeper, but that is only on one side. On the other side it is higher. I would suggest that one negates the other and it may offer no increased volume over teeth filed horizontally.

I also believe that some strength is added to the tooth as the cutting edge is not so long compared to the trailing edge or back of the tooth. However, because these saws are for me as my users, I filed them the way I like them.

I have not tried these saws yet (with the exception of the largest back saw, but I have refiled that since I tried it a while ago) so the small dags are the feather edge that I normally knock off with a brass brush or even my fingers and sometimes during the first sawing :rolleyes: .
Earlier I mentioned that with the smaller closed handle tenon saw I may have made a nonsense with the filing. The problem was that I used a thicker sawplate than would be normal for a saw having 14ppi. It is .029" compared to say .023. The combination of small teeth and relatively thick plate produce an unusual issue. The sloped filing makes a very short tooth. I will give it a try first, but I may have to refile horizontally (that's the file position).

I should add that normally 14ppi would be filed rip and the problems I have encountered are probably why that would be the norm. I can see from these pix above that in any event more filing is required as the tooth shape is not completely there.The camera has better magnification than my spectacles and headband magnifier!
When I took the pix earlier it was dark in the shed as a brief storm had come through, but when I went back out to take the pix above it was sunny and in a better natural light the Silky Oak shone better.
