Multico M1 Morticer clamping mechanism

[EddyCurrent]

Hello,
New to this forum but looking forward to browsing through the threads and hopefully making positive contributions in the future.

My Multico M1 Morticer is missing the original wood clamp, it's the one where there are indents along the bottom of the T slot.
I have a parts list and I think I can see how it works but could someone please explain the actual operation of how you move the clamp from one indent hole to the next.
It looks like you tip it forward so that the pin is clear of the indent hole, then slide the assembly along to the next hole and tip it back again so the pin engages, is that right ?
Also I will have to make one, unless someone has a spare for sale , so could someone please take a few photos of their similar clamp showing enough detail to make one.
Thank you.

Yep just like that

Welcome to this excellent forum. Sorry I can't help you but that's a mighty fine machine you've got yourself!

Hello,
I'm still needing some help with this please.
I now have the assembly drawn up but there is one detail I can't work out from photographs and would be very pleased if someone could enlighten me.
How is the end of the adusting screw attached to the clamping plate ? is it a ball end like a G cramp ? or something else.
From photographs it looks like the hole for the end of the screw comes riight through the clamping plate onto the surface that will butt up againts the work being clamped, why is is this ?

A few close up photos would solve my problems if someone would be so kind.

Thank you.

To answer your question, yes it does look like it's a g clamp type arrangement.
Hope these help.

Thank you so much, that was just what I needed. It looks like fabrication of that particular part might not be so easy.

It's a ball end, it just loosely fits on and the clamping pressure keeps it snug. The ball end gives some play which helps when you jig angled components into the morticer (such as the chair component shown here).

Thanks, good information. I can get the knob here; https://www.berger-tools.co.uk/Hand_Kno ... ews__Nuts/
there is one that looks just like the original, https://www.berger-tools.co.uk/Hand_Kno ... teel_Bush/
80mm diameter with M16 thread. I'm now thinking about doing this;

1. cut the ball end off an old G cramp leaving about an inch of thread on it and obviously the swivel foot still in place.
2. Turn down the threaded part to about 6mm
3. drill out the centre of an M16 threaded bar to 6mm for 3/4"
4. join the two parts together with devcon or similar.
5. weld or bolt the foot to the pressure plate (do this before step 4 so as not to spoil the adhesive)

Phone around some of the big second hand machine dealers like Scott & Sergeant to see if they have something from a scrap machine, or can suggest something from a current brand that could be adapted. If you make it then it would have to be done very well as it's subject to high stresses and strains, if you're morticing large sections in Oak you'll be tightening down on it as hard as you possibly can.

Good luck!

I reckon a record m130 clamp head ( or similar ) might be the easiest to alter. Wouldn't look as nice as the original but should allow for twisty movement if you could bolt it on a piece of metal that slid in the machine bed groove.
I notice ebay have got certain multico spares- Not the bit you need but perhaps if you waited long enough one might crop up.
Good luck which ever option you go for
