Circular Saw Blade Grinder

[Mike.C]

Has anyone used one of these

I have never even seen one, but at £226 it seems a bargain, or am I missing something, would we need anything else to sharpen a blade?

Cheers

Looks OK to me, I was thinking of a similar arrangement to mount a C saw blade on my universal tool and cutter grinder.

Looks very similar to the circular saw blade sharpener we had where I did my apprenticeship, no reason we it shouldn't work perfectly well

Thanks Brian, Shane. I have never come across one before (I send mine off to get sharpened), and so Shane's confirmation that they are pretty good is welcome.

Cheers

Seems quite a simple process where little can go wrong, they use a diamond rimmed disc and you very lightly hone each blade face and top edge. I send my blades off as well, and it is so cheap to do so I'm not sure one of those machines would pay for itself

It looks as if it will be ok for a quick touch up on blades, but I think it will end up being more frustrating to use than it's worth - doesn't look as if it can be set up to grind the tops of the teeth properly, which will need to be done every couple of sharpens and it's difficult to see how the grinding wheel would move in and out for certain blades.

The main thing that should put anyone off this type of machine is the dust produced by dry grinding - it's a really fine dust that can cause serious lung problems and irritate the skin.
Most modern machines that sharpen saws are now fully enclosed and wet grind - wet grinding produces better results as well.

Shows how far things have moved on. I suppose my apprenticeship was a long time ago - b*gger, I feel old now

Ah Ian, now there's a man in the know.

Shane I am positive that your point of view was valid not so long ago.

Looking at the vid it looks to work perfectly well as I thought it would. I did my apprenticeship here and they used a very similar system in their own saw doctors without any trouble, and if it produces good enough results for them I'm sure it's fine. They may still be using it now, I'm quite interested in finding out. As far as the dust is concerned you can always wear a mask.

I don't know how good it is but I remembered seeing an add for this http://www2.westfalia.net/shops/too...cular_saw_accessories/52004-saw_sharpener.htm. It is certainly a lot cheaper so potentially would pay for itself quicker.

I've absolutely no experience of the kit or the company other than at some point I must have signed up for a catalogue.

Anyone find a cost for the replacement grinding wheels?

When you mess up and damage the wheel you will be horrified at the cost of the replacement.
Additionally.....
How much will it cost to replace damaged saw blades.
Saw sharpening is a fine art as Ian has suggested.

Still....will make me and others like me happy when you need to buy new blades

With a condescending attitude like that, when I MESS UP, as you are so sure I will, you can be equally sure that I won't be spending my 'blade replacement fund' with you.

It's a shame that my (inevitable) failed attempts to save money should make you, and others like you, VERY HAPPY. :roll:

Personally I will still send my blades to Norfolk Saws to be sharpened - They do an excellent service and a 315mm 60t blade costs about £6 for clean and sharpen. Its not worth me investing in the machine or the time to sharpen my own.

Peeps,
The grinder in the link is very similar to the Autool machines we had, they work very well, this will have its limitations as did the Autool machines, however, they were 10x the price.
Remember that this machine will be built to a price, it will do the job of sharpening the teeth.
However, also please remember your saw doctor will do more than lick up the faces of the teeth.
Tips can be replaced and ground to match the rest, it is not only the faces that get done, often the tops also need doing and every so often the blade will need backing off, also the blade tension should be checked at every service, this requires training and experience, also if it is "out" then it needs re-tensioning, that is quite a skill, not something I ever mastered.
BTW even the pro's mess it up sometimes, and with a manual machine it will be your fault, unless it breaks, with a CNC auto you have a chance of the machine going wrong, however if you are careful and meticulous it can be done.
Is it worthwhile, that is your call…
