Thread: TSC10HB, 30-16mm bushing reducer tightness

I think you have the wrong bushing. It needs to be tight

I'v always had to tap mine into place (put a piece of wood over the bush, hit the piece of wood).

Where did you get the bush from?

Mine used to be a tight fit in both my blades, but is now only tight in one. However, as long as there is no slop it should be OK, but suggest you replace it or check the dia of the blade hole.

You realy should have a bush for each blade and the bush should be good and tight.
The bushes I used when I had a 5/8 arbour saw had serations round the outside and the needed a good firm belt or two to get them seated.... once in I didn't take them out even for sharpening.

be well aware that there is a difference between a 16mm and 5/8" bush. The blade, bush or whatever should be a snug fit on the arbour.

cheers

Sigh - I was afraid of that. Thanks everyone. Sounds like I was sold a 16mm when it should be a 5/8". At least, it makes sense since 5/8 is 15.87mm and that's more than enough for too much slop. Strangely I thought the old bushing I had was a 5/8 as well . Another trip to Fyshwick on monday... unless any other Canberrites know of anyone else selling them at Woden/Tuggeranong?

Thanks again,
Robert

Robert - i got mine from Carbatec, which is where I presume you got yours from. You could try Fitch's sharpening service - give them a call - but they are in Fyshwick as well. You could also try M&G who are also in you guessed it Fyshwick.

Cheers

Thanks numbat - CT only does 30-16mm reducers. They put me onto someone who put me onto someone who... no luck yet. <time passes="">[time passes] M&G have offered to machine one for me - looks like that's the goer here in the nation's capital.

Happy to report Carbatec Sydney sell the 5/8" reducers. I bought 3

Thanks everyone,

Yes, I think you need a tight bush.

Had the same problem, thought it was tight but once it started up it came loose and was not pretty after that so yup nice and tight.

Hi Guys,

Have I missed something.

Isn't it the 30mm size which is held in the blade. A few centre punch marks can lock it in.

My solution was to put some large washers which while still ever so slightly loose inside the cheek cavity are large enough to hold the bush mostly in the centre of the blade. I had some large 5/8" washers about 1/8" thick which I filed in thickness to do the job. The Cheek Washers actually hold the blade once it is tightened but because of all the washers and the bush it is centralised while tightening and can't move of centre anyway, even if the load stalled the blade.

Be sure the fitted washers are not clamping the blade but not sloppy

I have been using this for a couple of years with no problems.

Oh cripes, I'm not game enough to do that . Assuming the nut is done up really really (TM) tight, the rotation of around 4000rpm must (!) produce some movement of the blade. Gulp. Nah, I'll stick to a tight bush (wish I could find another one) gently but firmly clasping my arbor. Oh, and I hear you can get bushes with serrations on the outside at Fyshwick . Carbatec of course...
