Thread: Dyco Superfine 12" Table Saw

Some things that I need to figure out:

• I am going to use a VFD for it, I created another thread for that in the ELECTRONICS section.

• I need to remove the arbour shaft to replace the bearings, but it doesn't move. I have removed all the the pins and bolts from the pulley, but it simply don't move... Any tips? Here are some pictures:

Judging by the broken casting looks like someone has tried to remove it previously with a rather large hammer ��

Good project! Mine was a fun - Dyco 12" Table Saw. I did replace the 3-phase motor with a single phase 240v motor. This worked well but from memory required a basic mounting plate made up to interface with the original bracket from the saw.

Hey Charlie! I know it! Hahaha, I even added you on LinkedIn to talk about this (sorry BTW).

To keep it cost effective I am going to use a VFD since it is hard to find a B5 flange single phase motor here in NZ for less than 300 dollars (I am going to pay 79 on the VFD at AliExpress).

It is an amazing project though, I am really enjoying the process

Cheers!

Update about the arbor: I did it! 😅
I bought this bearing puller and it is amazing! Really well made and relatively cheap: NZD 50.00, very heavy-duty.

After I removed the shaft from the housing, I had to remove the bearing from the shaft and then a new issue arose: how to remove a stuck shaft woodruff key? In my case I kept pulling the bearing and it pushed the key out, the bearing broke though, but that's fine, since I'm replacing it.

Here is a video and some pictures:

Good one you sure you got the right guy on linked in? Didn't see the request.

I did consider a VFD but the one I looked at was a bit more than a new motor and wasn't confident in setting up a VFD myself (& wasn't keen to spend the $$$ on a sparky to do it for me) - I believe they are pretty straight forward mind you, as long as you have the motor plate with all the details you just have to put in the motor specifics. There are some really cool options too like slow start up and motor braking at shutdown etc.
Where it all got a bit fuzzy for me was the Delta vs Star motor considerations BUT perhaps new VFDs get around this automatically and it doesn't mater so much?
The other consideration was the lose of power via a VFD (not sure if this is still the case), was told to expect a lose of ¼ of the HP of the motor using a VFD. Probably not that big a deal if you have a 3HP motor mind you.
