table saw blade questions

[sunnybob]

I have a ryobi mitre / table saw combo machine that works quite well for me, but I think it might be time for a new blade. Its a 254mm x 30 mm.
When I cut 2" thick rosewood across the grain theres a lot of burn marks on the wood.

this is the blade that came with it so I suspect its a very general purpose contractors blade.
i would like to buy something that will give a finer cut as i use mainly hardwoods.

Never bought one of these before, so would appreciate guidance on teeth and kerf options without getting into wildly exotic and stupidly expensive territory of course.

I would suggest a combination blade, freud are a middle price range

It tends to be a compromise as ripping blades are the best for deep cutting with the grain but will chip out more on cross cutting.

Very fine blades, even sharp will burn on deep ripping cuts and itll be hard work pushing work through

I dont know if they do a 254mm which 10".

This blade is 2.8mm, I would check your existing bkade and choose the same kerf width or you may get binding issues with the riving knife.

:shock:
If 2" rosewood is easy to come by in Cyprus, then the next time I go I'm bringing an extra suitcase.

Its surprised me how much hardwood is available here. There is one woodyard that has huge baulks of timber parked up in the darkest corner, 5 metres tall and 30 cm plus in width. I have to use my phone as a torch when I go wandering in there.

So far the only wood I want but cant find is Padauk. Thats a lovely coloured wood.
I've even found a large pallet of Gombe. Dont ask me, I only read the labels. it comes from africa.

Getting back to the saw blade... mine is a 48 tooth 2.8 mm kerf.

How would you clean the teeth as they are quite heavily gummed up?

 

[RobinBHM]

Thinners of some sort cleans off resin

Acetone works well, proper 99% stuff you get on ebay, not watered down stuff sold as nail varnish remover. Wear nitrile gloves whilst using it as it will remove all the oil from your skin.

Acetone is also a carcinogen. We used to use it every day in science labs but you won't find it there now, except for specialised applications.

Acetone is also a carcinogen.

Since when? Not according to the on-line data sheets and environmental health circulars. Widely available to anyone "off the shelf" with no health warnings on labels.

Used every day by TIG welders everywhere for cleaning steel prior to welding

On 2" Rosewood a fine cut off blade is going to generate some heat so I would stay with a 48 tooth general purpose blade but make sure you buy reasonable quality like CMT or Axminster Premium and keep it sharp. Make friends with a local joiner who will usually be happy to send your blades away for sharpening for a fee

I don't think Acetone is carcinogenic, but Carbon Tetrachloride which we used to use in the drawing office is a different matter.

To remove saw blade pitch you can soak in paraffin.
A while back I got 2 x 4.5 litre containers from B&Q at a reasonable price. Will also need a suitable sized round washing up bowl or flowerpot dish, stand thing to soak the blade in.

Or use oven cleaner which is even easier to get hold of

 

[amilo2]

Go buy some Simple green,it smells nice and cleans everything...

 

[kevinlightfoot]

Oven cleaner is very good in my opinion.Place the blade in a bowl and take it outside,spray both sides and leave for a few minutes,pour boiling water over the blade and then wearing rubber gloves brush off the grunge with a nail brush.Give the blade a wipe over to dry and then a wipe with clean light oil such as wd40.Mr Muscle oven cleaner from Poundland and I believe it is only a pound it will last for ages and a clean blade will cut much better than one coated in resin.

On checking, I find you are right. I am out of date, and the situation has changed in the 20 odd years since I was COSHH officer for a large uni laboratory! It seems to be perfectly acceptable now. Good news, as it is a very useful solvent.

Thanks, Keith
