I replaced it with a porter cable that was on sale for 1/2 price, a $200 saw for $100. It's a good saw, but buy once, cry once. I should have sprung the extra and bought another Bosch.
+1 - Found mine in a local pawn shop in like-new shape for $40. Guess the pawn shop owner didn't have the internet to search what it was actually worth as I talked him down to $30. Mine makes table-saw perfect cuts.

And yes, great work and pictures Nimrod, thanks for sharing!

Curious to see how these handle pockets are going to work out.
You make it look so simple. Somewhat frustrating I must admit, but keep them pictures coming. Nice work, Nimrod!

...Like this:
Drilling the handle’s cutout end radiuses with a 44mm (1-3/4”) dia. cup drill:

Image

Cutting the straight edges:

Image

The handle pocket will eventually be glued like this:

Image

And this is how it will look from outside:

Image

Of coarse the cutouts outer edges will be rounded, as well as the cab’s corner.
Also, the handle inner corner (between the two cutouts) will be fitted with a rounded filler.

Can you tell us the distance you're using from the corner to the edge of the handle? Also, what size of filler have you found to be comfortable? I'm just asking since my last handle was not as comortable as I wanted.

Really nice work!

Are this white foam good for fillers, its not too soft, or acoustic absorbent ?

Thanks..

I think/hope this material is ok, as I have used it also for my DR290s…
It is relatively stiff and closed cell foam, so to my understanding should do the job.

Routing done. The corner rounding was straight forward, 5mm radius for the handles cutouts and 10mm radius for the shell/sides corners.
The front lip edges were just hand sanded to create a radius of about 2mm. I've added recesses for the cabs feet on the two optional bases.

Image

For those interested, here is how I did the logo routing (CNC = See & Copy… :wink: )

The router is fitted with a 15 deg. conical bit and a template follower. The depth was set to 3mm (over the template's thickness):

Image

The cab's panel is marked for the center of the logo (in this case, the center of the panel):

Image

The template is positioned up to the center marking and clamped:

Image

The "d" is fitted with the first stage removable 'sub-template':

Image

Routing the first stage complete:

Image

Replacing the "d" sub-templates:

Image

Completing the second stage of the "d":

Image

Template removed, edges sanded lightly, done:

Image

Next: minor Bondo touchups, sanding and… paint.
