It’s not a good idea to balance the wheel as it is…on it’s 25 mm shaft. Bearings of this size have far to much friction so what I do is temporarily mount the wheel onto a smaller set of bearings (10mm) that have a much lower (relative) friction.
Above: I don’t have any small bearing left so we had to ‘borrow’ the pair of thrust bearing from the lower blade guide assembly.
Back in the shop and had a tidy up, here is video to show the results of my efforts to minimize wheel wobble. Before I put the wheel back onto the saw I will need to balance it again so that’s the next task.
The main challenge when mounting bearing flanges onto either side of a wheel is to minimize wheel wobble. Run out is not an issue here, that can be taken care of later. The purpose of the 4 holes in the wheel is to allow clamps to be passed through to hold the flange bearing during the gluing stage.
The wheel needs to be mounted on the workbench so I removed the lower shaft from the saw and made a temporary mount for it which is clamped to the workbench.
I have made a new flange block and pressed in the 6205 bearing.
Purchased this hole saw set from the local Sunday market for $25 bucks and for the outlay it’s surprisingly decent quality. The bearings I’m using are 6205’s (52OD/25ID) and the closest hole saw size in this set is 51mm so after drilling the hole and careful clean-up with my improvised drill press drum sander to achieve a nice press fit into the block using a bench vice.
I have removed the lower shaft from the saw because I’ll need it to mount the new flange onto the wheel – more to come on this.
The saw looks a bit sad with no lower wheel.
The table, supports and lower blade guard box (old kitchen drawer).
A closing pic of the bearing guides.
While using the beast today noticed a strange creaking noise emanating from down below underneath the cutting table? Stopped the saw and removed the lower blade guard box to have a look and noticed that the front bearing was separating itself from it’s wooden flange which has cracked/split on one side.But wait…the front bearing can’t move forward because it’s secured with a hose clamp on the 25mm bearing shaft? Had a look around the back of the wheel and no hose clamp to secure the rear bearing – my bad. So…except for the front bearing everything else (wheel and rear bearing flange) has been slowly working it’s way along the shaft to the rear exposing the front bearing – good thing I stopped to investigate!
The bearing should be flush with the flange – which has split!
You can see how it cleans up, we have a sloping driveway so I work from top to bottom.

He lives in a two story hutch that I built some years ago which is located in the downstairs entry foyer. This is a traffic bottleneck so he’s usually up to date with everyone and everything, if you want to know something – just ask him.
UPDATE 19/01/15 – Just got back from Winplus in Boronia with a new camera, straight back up the ladder to install and working OK. Tonight I will check night mode operation!
Camera No 4 (Backyard) is dead – RIP
This is the second camera to die so off again to Winplus in Boronia to exchange for a new one. Weather improved this afternoon so decided to install the camera which I had running on test overnight next to the DVR. Continue reading “Cocoon CCTV Security System – camera problems”
With reference to:
Water tank pump has sprung a leak!
Got a call today from the Stihl Shop informing me that there are no spare parts available to repair the pump (what a surprise 
) and to trip back over there to collect the required paperwork so we can get a full refund from ALDI.
I was expecting this outcome that’s why I went off to ALDI last Wednesday and bought the same water pump while they were on sale as it’s likely they won’t come around again for at least 6 months.
So…for the original purchase price of $99.99 we start again with a new pump and 12 month warranty period – happy with that.
