Flange Sets

Hi. I may be justified in changing what I believe is the flange set for my machine, so I can fit cutting discs with a 25.4mm bore.

I attach a picture. This set is for discs with a bore of 30mm. The hole that fits on the motor shaft looks to be about 15mm. The flange diameter is about 41mm. One is about 7mm thick, the other about 10mm thick. A seperate regular hex nut affixes these things to the shaft, with saw blade in the middle.

Do you think I might be able to source a new set for saws with 25.4mm bore? Thanks. Rich

Don't you just need a reducing bush?

In this case you could not use a reducing bush. I mean, to make the current flange set work, I'd have to reduce that raised part you see on the right hand part in the picture, from 30mm to 25.4mm And put a suitable washer into the other part with the recess.

I may be able to find a flange set for a chop saw.. Not sure.

EDIT: Actually, if that raised part were taken down to a diameter of 25.4mm, then, to put things back as they were, then I could use a washer to bring the diameter back up to 30mm. Maybe that's the best solution. Except I don't have a lathe (that can take 41mm diameter).

Actually, to take that 30mm raised part (seen on the part on the right hand of the picture) down to 25.4mm, I suppose it's possible to bolt that part onto a 15mm threaded bar, and to put that into the lathe chuck.

Trying to source the same set so I can modify one of them (I'll have 2 sets then). Will let readers know how I get on.

I can get the flange set illustrated above for £30.90. That's expensive. I think I'll buy a lathe and make my own. (I have lots of other jobs I could use a lathe for).

I think that last post might indeed be the way to go.

£30.90 ???? a bit rich for me !
