Sticky rebate support on morso!

bigred · Post by **bigred** » Mon 21 Jan, 2008 9:30 pm

Hi guys, since I'm pretty new at this game, forgive me if my query has already been posted. It's just that the right rebate support on my morso does not slide back on it's own, I have to "help" it along. Very annoying!!

Has anyone come across this problem before?

Spray a little penetrating oil in the track. Rub with a rag to remove buildup - then reapply another light coat and let dry.

I've already tried this, but to no avail. Well, I actually put a little grease in the track and rubbed of the access. Any other ideas?

I always move my rebate supports manually as with some mouldings they seem to dig in and get stuck, or move or rock the moulding. They aren't the best design for moving freely, so I got into the habit of moving them myself very early on.

Light oil (3 in 1 type, not WD40) would be better than grease, which will soon get clogged with muck & chippings.

Thanks for the tips, it's just that the left one moves very freely. I'll not give up, Cheers.

as mentioned, 3 in 1 oil is probably the best item to use, it cures all manners of morso problems, much better than that evil WD40 stuff, baaad baad thing to take anywhere near machinery in a picture framing workshop.

can prove costly if you use WD40 on some machinery, it swells the bearings up, best to use something like "back2black" car tyre shine - (this mostly applies to the Keencut vertical board cutters)

This question was asked in Pete Bingham's 'agony' column in TPB which I received today.

He says to remove the supports and rub your finger along the edge - at the end nearest the blade you may well find a slight burr.

Remove it with an oilstone and some light oil and also polish along the edge, do the same to the edges that the supports run in their channels on.

It might be worth taking the support out and checking for rough surfaces, but if you find any don't use sandpaper, files or brillo pads on them, they're too rough. a gentle rub with oiled 0000 grade wire wool can help.

Ah darn,beat me with a similar answer!

I think its a design problem with the rebate support itself, it seems to work perfect on some profiles but on others it digs into the moulding like Steve said.
The use of grease would not help with the problem only make it worse, as it would hold onto any dirt and clog the groove where the supports run.
I use Silicone Lubricant Spray and find it good, it does not leave a tacky surface for dirt ot cling onto, but I need to spray it once a week.

I think there was something on the Morso website about problems with the rebate supports some time ago, but I cant find it now.

file the edges "rounded" grease works (!) or silicone spray.
They have never been too good.

I have this problem with a brand new set of auto height supports. They are supplied with a new t slot track/bottom blade profile which is why they are so damn expensive. Anyway the right hand support moves freely but the left shows more resistance at the centre point of the slide so I have to move this manually after the second or third cut (ish).

Removing the bottom of the support (the T track profile) and running it in the right hand slot shows all is ok. The problem is in the machining of the left hand T slot. Neither silicone spray or 3 in 1 made much difference so I eased the edges with a file. A bit better but I am reluctant to take too much off as the slide will be sloppy in the areas that currently run ok.

I have developed a technique that involves first cut, move left support away, morso click, support back, cut etc. Currently looking at an engineering solution that will retract the supports when the morso bite knob is touched and push them back when released. However this grand idea may take a while to develop....!

I used to have the same problem until I fitted this....

OK - Eejit-features here needs some help.

Howz it work?

Clever init?

As the cutting block moves in and out the rebate support always stays the same distance from the fences. There is one each side.
It's a while since I fitted it, but I assume it's an official Morso accessory.

Just checked, and the screw holes are there in readiness....

How on earth do you two wake up in the morning?

I just got up for a cuppa, going back in a mo.

That rebate support is on the accessory list: http://www.morso-guillotines.dk/webuk/m ... o_supp.htm

I had to drill mine.

I am just microwaving the cuppa I made at 9pm.

Why sleep when you could be up and about looking for previously undiscovered holes in your Morso.
