Thread: Saw Blade Inserts.

Are you sure that you've got all the sizes right? There's 16mm and 5/8", they're close but not the same. Not sure about the 20mm, never owned any thing with 20mm, but I do have some 7/8" which is close to 22mm from memory. You can get bushes that are metric/imperial like a 16mm/1" or a 5/8"/25mm. The arbour bushes should be a snug "push-in" fit, not a tight "bash-in" fit. Check all the dimensions with some good verniers.

G'day Mick,
Thanks for the reply.
The 16mm fits over the shaft like a beauty.
The hair tearing fit is between the blade and the insert supplied with the blade. Its an Irwin 10 inch 80 tooth blade and the insert was included with the blade.
Not fitting well.

Noel, I bought some blades from Northwood tools that have a 30 mm hole and inserts to step down to 25.4, 16mm and 5/8.

I found I had to support the blade an a piece of MDF and use another piece of MDF/wood to knock the bush in. Once in they were a very firm fit and it took a bit of a knock to get them in.

I made sure that bit of MDF supporting the blade was smaller than the diameter of the teeth, ie it was sitting flat under the saw disk without touching the teeth.

Does that make sense?

Lay the blade flat on the bench and sit the bush in place. Give it a firm but accurate tap, this should start it in the hole, then drive it home. If that doesn't work, take it back. Good luck

Mick

Thanks Fred & Mick,
That all makes sense.....I'd sort of been trying to do it in the "air". Grrr!!
In the morning I'll have a quiet gp again.

Just a follow up!
Everything proceeded calmly today......all went as you both said.
Thank You.
(never used an insert before..always bought the right size blade)

All's well that ends well

Hi,

a bit late,

but I was told to use the drill press to "press' the inserts in.

The problem I have is the inserts dont need any pressure to go in 30mm --> 5/8 and fall out when trying to put on table saw arbor.

I'm going to send these new freud blades ands inserts that were supplied back to supplier and get blades with the right sized hole.

Maybe this is a problem specifc to Freud.

When I bought my TS, the supplier threw in a Freud blade. It came unpackaged and didn't include the correct insert.

So I grabbed my insert from a cheap Irwin blade I already had. No way would it go in the hole.

Solution number two was to order the correct size converter/insert from Timbecon. It also wouldn't go all the way in, but it was a lot closer than the Irwin insert.

Solution number three was to place the insert in the freezer for half an hour - to try to make it a fraction smaller. Then I used a soft mallet to encourage it into the hole. It worked. I hope it never comes out. I've been using it for a while and it has stayed nice and tight and solid.

I probably should have insisted on the right Freud insert, but as it was a freebie, didn't think this was the right way to go.

I think the drill press route is a good idea.
