Making gaskets... with the mill
« on: September 02, 2019, 01:08:21 PM »
Not sure if this is the Right Forum...
I thought About making some complicated gaskets with much holes and other shaped forms.
First thought was to let them be lasercut from a shop. The Price was very high so i came to another idea. Why not use the CNC Mill to cut the gasket?

Long speech short sense i bought a dirt cheap set from China with a drag knife holder and 15 knifes for arround 7 Euros.

I mounted the knifeholder with a collet into the spindle and taped the gasket paper to an wooden plate onto the table.
Some g-Code did the rest.
First pics Show some intake manifold gaskets for my 914 EFI conversion.

The gaskets came out realy nice  :cartwheel:

Hello Michael,

Your CNC cut gaskets look very very good. Well done. :ThumbsUp: :ThumbsUp: :ThumbsUp:

Can you make holes for small screws with that drag cutter? How small do you think it will go?

I have been thinking about gaskets for the Jupiter and discovered laser cut was too expensive to consider.

Please can you tell us about the drag knife cutter and exactly where you got it from. Was it really only 7 Euro? I could afford that :lolb:

Cheers

Mike

Those look incredible Michael.  Just curious and not to hijack the thread, but for those of us without CNC, has anyone tried one of the "Cricut" machines for gaskets? Basically they are the same principal though in a small dedicated machine used by scrapbookers, etc. and available at craft stores.

Mike the last pic Shows the gasket for the intake/exhaust mani of the seal. the screw holes are aprox 2.2mm.
Haven´t tested any smaler yet.

That black paper is 0,3mm thick and the green one is 0,5mm. Both worked without any Problem. That littke knifes must be realy sharp.

What size of holes do you Need, i can do test cut.

Hello Michael

I put the German description from your link into UK e-bay and found a British supplier. Cost was £5 and delivery is this week.

2.2 mm hole is what I need for 8BA screws, so they will be perfect.

Thanks for posting this information. It will help many of our model engine makers in all the corners of our small world

Grüße

Mike
