Thread: Hammer N4400 Tabel mount failure.

Is that aluminium or zinc? The weight should give you a clue. It's not a very robust design by the looks of it, especially when you consider that a lot of owners lift/move their saw using the table.

yikes!

thats a pretty catastrophic failure...

Following along just to see how Hammer responds. To me even out of warranty that deserves a good looking into.

Actually it probably is zinc. I think cast zinc alloy is actually stronger than aluminium from memory. Its should be machined cast iron. I guess that's how they save dollars..

I'll see what felder come back with. At this stage if they charge me I'll probably machine something out of steel. If I take it easy I should be able to do it on my CNC router. The gear might be a challenge though.

Just did a google for trunnions, looks like they are a common failure point in many machines. Maybe making my own is the way to go, plus I could add in bearings to make it smoother to operate.

If you don't end up making your own, and should the Hammer trunnion still be made from the same stuff, there are seemingly some possible options.
Just looking at Laguna's site, to see if one could source a trunnion from Novellara, those castings are dependable, I can't speak for others cast iron,
it seems one could buy one for an LT16, though it looks like roughly twice the price of Grizzly, as the segments are sold separately

I can't see the pics to see if those are a simple job like on the older ACM saws, with just a single bolt to lock things with a spanner.
It may well be the case of them being fancier spec from Laguna.

If the standard, then might be worth noting there's at the very least, two differing sizes, possibly more to choose from, should something from ACM UK, or even directly be available,

The Grizzly trunnion has bells and whistles

I presume Carbatec or whatever brands are popular must have something also.

Be interesting to see you make yer own, especially for someone who might be a bit tight for space, should it be the case,
I've often wondered why they don't make a compact saw with enough resaw height to enable a swinging trunnion,
as it would make a lot of sense for some.

Good luck

Hammer sure is disappointing in quality for a lot of the ad ons.
We have a 12” under and over jointer thicknesser which is only used as a jointer.
The die crap bit wot holds the guard recently died, see photos below.
The fence is a bit so so also, locks square if you hold your mouth right and use the appropriate language whilst doing so.
We also have their table/panel sore which like their other kit is basically well built but the detail leaves a lot to improve on. The sheet metal cover plate over the blade is diabolical, jambs most of the time and is completely unnecessary.
I would have their stuff in my own shed but would be doing a lot of modifications on their crap bits.34A90B58-3B36-45E9-B111-09BB243B28E8.jpgD1893F38-43C9-40EC-A0ED-6854BBF8678D.jpgA5FE20D2-BFF2-4FAA-B6AC-E0D16AD36A68.jpg
