There are only two ways to attach those table extensions… with the shiny side up, or the shiny side down… so yours looks like you got it right :)

The Biesemeyer fence manual specifically states that the holes are NOT supposed to line up. If you want to attach the fence to the wings, you will need to do some drilling.

Cheers,

Well ok then. I suppose if Biesemeyer says they aren’t supposed to line up, I won’t worry about it!

If it were me, I would definitely drill the extra holes. I’d put two in each wing.

Cast iron is not difficult to drill and tap.

You don’t even need to tap it. You can just drill through holes and bolt it on with nuts on the back side.

What Jonah says is correct. But it depends on where the hole comes out on the other side. Sometimes there will be webbing or some other uneven surface there, in which case tapping is a good way.

Good point. In any case, you’re right that most any reasonably sharp twist drill bit will go through cast iron quite easily, and tapping isn’t hard either.

Thanks guys, but I suppose the question is, SHOULD they be bolted, not CAN they be bolted. From MrUnix’s post, it appears the manufacturers did not intend for them to be bolted, is there a reason for this, or should I just go for it?
Are everyone elses saws bolted?

I bolted my rails to the extension wings. The wings attach to the table with very beefy 5/8” bolts, IIRC, but I figured the more support there the better. IMO, there’s no downside to attaching them to the rails so long as you make sure they’re flush and level with the main table.

Have your say...
