Circular saw spring clean

[Marko]

but by re-tipping do you mean sharpening or do they literally put a new tip on the teeth?

 

I've just had mine done as it was just starting to feel like it was becoming to much of a fight. It was back within a week and as good as new. No tips needed replacing so it was just a sharpen.

 

I have always used a squirt of WD40 on a build up of resin. Seems to clear it fairly quickly. Petrol would probably work better but I can give it a douse of WD40 without dismantling (or stopping) it.

I think there is binding, but the saw generally has the power to cope.

 

I could be wrong

 

Thinking about it more the chainsaw blade works differently as you have a blade on the side of the cutter so a second bite at the cherry so to speak.

Hmm, interesting!

 

The blade has done about 200 cube since new so may be time for some tlc. Excuse my idiocy, but by re-tipping do you mean sharpening or do they literally put a new tip on the teeth?

 

I generally pay about 70 quid and the blade is fully re-tipped,I believe they used to be braised on but are now stuck on

Thanks Alec,

 

Sounds like you and Beau may be touching on similar things. Are you coming over for the retort gas analysis? Perhaps I could show you the saw at the same time?

 

Yes, we're touching on similar things. The idea is that the teeth make a cut wider than the body of the blade (same on a chainsaw). On green wood this typically needs to be wider than on dry wood. In theory, the body of the blade should not even touch the wood, although in practice it usually does a little. The fact that you were seeing marks on the blade suggested it was worth a look, although if the teeth are dull they may be pushing fibres out of the way rather than cutting them cleanly which means they spring back and rub more easily.

 

It isn't too hard to touch up a dull carbide blade with a diamond file. You file off the top rather than the face. That circular saw I brought over made a fair few 3.5" deep cuts rip cuts around 7' long without struggling, despite having half the teeth missing! That had been sharpened with a a diamond file the night before - prior to that it would have struggled with a half inch deep cut.

 

Not sure whether I am coming over or Andy is - depends on whether his wife lets him switch his working days (he is part time and doesn't generally work Fridays).

Thanks Marko, I'll give WD40 a try too.

 

Is it expensive to have them professionally sharpened?

 

Anyone other than Alec had success sharpening their own? Alec is very clever, I am not.

I am not very clever but used diamond stone on my workshop crosscut circular saw blade. Didn't make it cut like new but much better than leaving it be. The tricky bit is to have steady hand to keep the stone at the right angle. Be aware I have heard (second hand) of sharpening places being snotty when they have seen you have had a go yourself so up the price.

I took mine to a new place for sharpening last week, they commented that it was no long a circular saw, but somewhat egg shaped. It has never worked so well having had a sharpen and alignment. Worth taking it off the bench for and perhaps the best £12 I have spent recently!

Haydens in Braintree charge us around £20 plus vat to sharpen a 700mm blade, if any teeth chipped bad they change for a few quid a tooth. Anywhere around the 200m3 level would be good time to get it sharpened, as said a blunt blade notices more on some woods than others and always on deeper cuts.

Would not waste my time in doing any thing other than a pro sharpen and teeth check , definitely worth it.

The sharpening cost £8.99 +VAT and delivery for a 2ft dia blade (plus postage) 3D Tooling at Bolton. You can post them if you are not on their weekly round.
