I made a start on this yesterday and gained an understand of how the two blade guides work.
Yesterday It seemed like both the blade guides had to be mounted at an angle in order to ensure both side bearings touched (or were at least close to) the blade.
Today I had another look and I realised that although the blade was entering the insert in the table centrally, it wasn’t running centrally in the guard that runs down to the upper blade guide.
I slackened off the blade tension and the 4 bolts which hold the upper wheel assembly in place and adjusted things so that the blade ran centrally in the guard, then re-tightened the bolts:
Because the blade is now centered in the guard, the upper and lower blade guides no longer needs to be at an angle (although it no longer enters the insert centrally I’m less bothered by this)
I was unable to mount the upper blade guide as far forward as I would have liked due to a radius on the guard:
I removed the blade guide to give easy access:
Then having covered the table with newspaper to catch the filings, I filed the corner square:
Update 21/04/2013: I have now done similar to the sliding section of blade guard on the other side – see Part 4 for details.
I then used the two screws which hold the blade guide to the guard to get it roughly in position so I could use the adjustment of the guide only for fine tuning:
The guide can now sit exactly where I want it:
Adjusting the guides in situ is pretty fiddly, particularly the lower one, although tilting the table to 45 degrees helps for some actions.
I also found that tightening the thumbscrews (top) or allen bolts (bottom) to fix the side bearings can move them slightly, so I used a piece of folded paper to ensure the blade wasn’t being pinched when I did the final tighten (I think I saw this on the Workshop Essentials DVD).
I adjusted the table so it was square to the blade:
Recently several people on UKWorkshop have asked about the W730 and one wanted to know if it was up to cutting 8″ beams.
The largest lump of wood I have in my workshop is an 8″ x 2″ offcut of Beech I got in January with some nice grain.
I’ve been saving it while I wait for inspiration on what to do with it, but it has a check in the end I don’t feel so bad about using that end for a test cut:
Even with the supplied blade fitted (about a 4 TPI) the W730 had no trouble cutting through the board up on edge (so about 8″ depth of cut):
I don’t think I’m completely finished tuning the saw, as the blade is slightly further forward at the bottom than the top when viewed from the side, but it’s certainly ended up a lot better than I expected at times yesterday!
