Problem With My Domino

[BrotherNov]

Having an odd problem with my Domino.  I took it off the shelf where it had been sitting for quite some time unused, maybe a year.  Needed to swap out the cutter, and had a difficult time.  After finally swapping cutters I couldn't get the "Head" of the unit back on - the cutter housing (or whatever its called rubbed against the lower plate.  I waxed the plate which helped a little, but it's rubbing too much for the springs in the shafts to push it back out of the mortise.  Am I doing something wrong?  Do I need to send it in for repair?  Thanks in advance for your advice.

Seems odd. I suppose that it's possible that the fence rails on which the motor/cutting assembly slide, could have sagged while sitting on the bench.

That's the first place I'd look based on how your describing the problem. Measure the distance between the domino base and the rails at their ends vs the same measurement where the rails attach to the fence.

I'll do that, but it was in it's systainer the whole time it sat idle.

That's an interesting one. Because it was in a Systainer, that rules out most of our initial ideas.

You might want to use a straightedge to make sure that the plate isn't bent at all.

It could also be that the lubrication has congealed. Does that seem to be the issue?

Clifford had a similar problem and it turned out to be the plastic dust collection pipe was not installed properly.  Between Clifford and Cheese they were able to figure it out.  Search "Domino not plunging smoothly"  and you will see some pictures and description in the original post.

Lube doesn't seem to be the issue, I can push the plungers in with my finger and they seem to be functioning correctly.  A google search indicated another user had a similar issue caused by a misaligned dust extraction port.  I'll check to see if I may have moved it while I was wrestling to get the bit out.  I studied the machine for quite some time trying to figure out what happened during the cutter swap and I couldn't identify anything that looked out of place.

BTW, I really appreciate the quick attention to my question, you guys rock!

Did something else go wrong whilst you were trying to remove the cutter?

No sir, it was just very very difficult to get the one that was already on it off.

It is possible you inadvertently torqued something when trying to
remove the cutter depending how you applied pressure. If it was not rubbing before this
would be my guess. I put my thumb on the spindle right next to the wrench and pull with my fingers: one hand only. I would worry if you set the tool on the bench and just pushed down on the wrench without supporting the spindle itself. Not saying you did this but that would be an assignable cause. A little Never-Seize on the threads and shoulder will keep the bit easier to remove.

Yes that's possible

Every now and again I put a tiny dash of oil on the thread of the cutter spindle before fitting a new cutter.

When I tighten the new cutter I apply so little pressure that it might be possible (please do not try) to undo the cutter using your teeth. To say it is just "nipped" is an over statement.

I suspect that one could just make it finger tight but I have not tried this. It will tighten itself as it cuts.

As Peter explains, it's the metal interface of the cutter base that's being torqued against the shoulder of the bit holder that can hang the bit up. Oil works, however, like Greg, I prefer Never-Seez as it will always leave a microscopic film of lubricant on the item. This coating can only be removed with acetone.

I've had to reset the dust port also. Take the screw out that holds the port on, cycle the fence. If it feels okay, reinstall the port. I can be a pain getting it aligned to the boss.

Well, it's not the dust port.  I removed it and the unit still won't slide right.  I'd like to believe I'm of at least average intelligence, but this as me baffled.  Even though they seem to be touching, I can force a business card between the motor unit and the base plate up to the last 1/4 inch or so of travel, I think.  But it's sticky all the way through the range of motion.  I can't find a single place where the fit/finish looks to be out of whack.  It's not like I dropped it or anything, I just had to sumo wrestle the bit out.  Here's some pics, do you guys see anything wrong?

 

[tjbnwi]

Nothing obvious in the pictures.

The the bit off, start the unit and cycle the fence without cutting anything, see how it feels.

Tom

 

[BrotherNov]

It takes considerable effort to cycle, all my strength in fact.  I've lubed it well. Appears I have a service call in my future.

 

[tjbnwi]

That's just weird. Take a good look in the rod ports, see if there is anything obvious.
