I recall these being discussed fairly recently regards fine cross cutting of finished timber .
I've got to get some new blades for my table and hand saws so thought I'd try them but cannot find any on E bay.
Anyone got a source for them at a decent price ?

Doesn't need to be stainless steel, generally the more teeth in the blade gives a finer cut I find

[paul.lovejoy]

toolstop normally have some good deals but ebay is generally good just get branded blades you pay for what you get and quite correct more teeth finer the cut 48 teeth is a good all rounder 60 teeth is a fine cut 72 very fine but dont tend to last that long all depends on what your cutting a lot of

last blades i got were of ebay bosch and dewalt sold in a bundle of 3 teeth sizes and reasonable price

Speaking of fine cuts.. this went through my mind the other day as I sliced some 12mm construction ply up with a hand-held circular saw; what's the best way to cut ply so that the 'top' face doesn't splinter off in big chunks as you're cutting it? The blade on the saw is whatever one came with it 

[horsecow]

Its very hard to get it to not splinter. Generally I'd cut it upside down as the bottom edge will always be good. If you need two good edges then you need to use a blade with a lot of teeth, 72 probably, and put some good strong tape down where you are cutting. To get a perfect edge its best to use a festool or similar saw which comes with its own guide, these are fairly expensive if your not using it every day but they will give pefect edge every time. I had to finish a ceiling with veneered plywood sheets and this is the saw I used, perfect job.

Thanks Paul ,  I'm familier with TPI's and the type & quality of cut of greater toothed blades. I have to re stock blades for my saws and wished to include some blades specifically for cutting stainless steel which may be better for fine work I do whilst making some furniture . As I said there was a discussion some months ago re their suitability and performance when cross cutting and I thought I'd try some .
I'l try another search and see if I can find the poster of the info.
Cheers

gotcha now never used stainless steel cutting blades in my day in shopfitting they wernt around used a jigsaw bet the metal gets a bit hot we used ali cutting blades same principle with the back slung teeth was always a nice fine cut to only problem was you had to watch the ali did not weld to the blade mind you the saw of the moment then was the elu flip saw my how times change and i still have a working one buried in my store right old boneshaker now me and the saw

problem 1.
get a high quality blade with lots of TPI

2. take a very light pass first  - about 1/3 way through the top ply

3. use a high power saw - the less it slows down whilst cutting, the less split-out.

4. put masking tape along the cut line.

5 put another piece of board above the piece you are cutting to hold down the fibres.


in order of effectiveness - 2, 5, 4,1,3

I use a high power circ saw with tct tipped plus the greatest number of teeth I can find and only very rarely (its usually a mistake I made by rushing) does the edge become raggy.
I cannot see why stainless steel will make any difference cos the ones I have used in my jigsaw all end up overheating whether the pendulum action is on or off.
Its a matter of choice I suspect........

the worst thing anyone can do is to force  something to cut if the blade or whatever is sharp and cutting at its own pace  hings should be prettyt good, other things do help as mentioned above
