I own a bandit 12s10 and have just replaced the guides and some other guide related parts. You must match the guide size to the blade size and blade kerf. The blade sizes are from min 1/8 to max 1/2" and then thin or thick kerf. If for instance you try and use a 1/8 blade in a 1/2 guide the blade will slip into the guide and it will take the edges off its teeth and damage the guide. The other way round then the blade wont be supported properly and it wont cut strait – in theory.
But dont be put off because this saw is so good and smooth and stable that even with a blade thats to big for its guide or some homemade bodged up guide it still cuts straiter than my brand new (made in Taiwan) Startrite 352! Yes that was my mistake and it cost me a grand!
Anyway, the guides cost £16 fromAltsaws (just before Christmas).
For ripping get a 3tpi thin kerf blade with its corresponding guide – thin kerf gives less wood wastage, less sawdust and less strain on motor. And only use it for ripping. And for curved, a wide a blade as the curve will allow (see the chart on the saw) and also its guide.
With these guides its a good idea to go along the back of the blade with an oil stone to prevent undue wear.
I own a large woodworking shop and have had over the years an original 301, an original 352, a new 352 and a 12s10 (plus lots of other makes) and this saw is by far the best, it cuts straiter than our table saws.
Hope this as helped.
