"Nib" removal on MDF cutouts edges

[EddyCurrent]

Sounds like you need both
The biggest problem I have with bobbin sanders is bobbins, the price I mean, it can get expensive. So I use these in a drill press; http://www.axminster.co.uk/axminster...-sanding-drums
It means you can use strips of regular abrasive from a roll, much cheaper.

I think that you can afford to leave your tab much thinner, If I use tabs I only leave about 0.5-0.75 mm thick material to cut away,
this is easily done with a scalpel. Not much "cleaning up" at all. Do not try to brake the piece out as this makes more work. G.

Of course this applies to small pieces in thin material (4mm mdf 2mm cutter). G.

Hmmmm,

I'll have to experiment. I see your point about depth though.

Safety wise.... I'm unsure about having SWMBO using a scalpel... Might give her ideas !

If your just cutting out largish shapes on regular basis and know roughly where they will be on table then think about Vacuum pods.? Pods not bed.
With vacuum pods you can positon them so they hold the material such that the vacuum seal is never broken so needs little vacuum (Henry will easily hold) and they hold the part clear of the bed so you can profile all the way around at full depth.

. . . think about Vacuum pods.? Pods not bed.

But they seem reluctant to show a price, unless I've not found the right place yet.

What I never mentioned any company.? . . . . . I meant to make them not buy them.!

HDPE or any plastic is perfect, chopping boards from £1 shop are great. Just route groves for neoprene gasket and hole for vacuum and away you go.

Here you go Eddy just like this. . . .Simplizzz.!

eBay item 191260263022
Looks promising,,,,

Mind you I really need to get practicing now I have the machine home.

Could do with some simple pointers and info on Zero points for work and axis etc.. I've forgotten more of what I learned 35 years ago than I thought

Well, at that price I've given it a punt... Now to persuade the router to cut a nice neat series of slots for the gasket in a suitable sized 19mm ply or MDF board big enough for a multitude of sizes etc.
Having a good old Henry vacuum I feel some engineering needs doing to make adapters to plumb it all together.... Now where *is* my good mate Mark (A toolmaker) hiding.....

OOOOH !

Now *that's* an idea I like....Having only a few days ago purchased said small pillar drill !
Nowt fancy, but a useful, (Even more now) tool.

Thanks Eddy
