Adapting a 1

22mm hole size slitting saws seem as rare as chickens teeth, plenty of 1" hole size in the diameter I want.

Has anyone adapted 1" to 22mm with a spacing ring? I do this with wood cutting saw blades with no apparent problems.

I see no reason why you cant do the same as your woodsaw blades as long as you can turn the ID OD and the thickness (thinness!) you need.

Actually precision concentricity is probably not that important. I have found that slitting saw blades themselves are not particularly concentric and always seem to cut on part of their circumference. Last week I snapped a section of blade off when moved the job sideways with the saw still in the slot it had cut (blade not rotating). As it was the first of 4 slots I wanted, I thought I would run with the broken blade and it worked fine.

If you think about it grinding wheels are used with light plastic spacers routinely..and these are driven va the flanges..saw rpms in most cases (centerdriven) are much lower..

I would still aim for as concentric as possible..make "washer"with step rather than annular bush.

On page 9 of the link you have them with 22mm hole, but a spacer ring will give no problem and is also much cheaper. Niko.

I think I will go with a spacer and buy one of the 1" hole variety to get me over the present needs and then buy a 22mm one from further afield.

I just wanted to see what the forum thought about it, thank you for the responses.

My cheap and cheerful arbor has a stepped and sprung centre to take a wide range of sizes.

I have one of those as well & have found that the steps are non too concentric & a sloppy fit within ea.other & do move when slitting even with the collar tightened up as far as poss' plus the inherent runout of the blades has caused the blade to bite in & stall my mill (only tried it once). Will now be making a new arbours to fit ea blade ID, or one only & get blades with one size ID.

As for the runout of the blades I suppose those with Stent / Quorn / toolpost grinders would be able to true up any eccentricity, will have to stick that on my toduit list (H.Hall grinder toolrest?) .

I'v got a number of saws, and I don't think there are two of them with the same size hole, so I have made mandrels for each of them. But you should be ok with a saw bush, you'll possibly find that your supplier can give you the right size off the shelf. Ian S C
