Thickness Sander

[Jibber]

As a little thank-you for the answers: Meet the secret circle-jig-3000







Not very accurate because the jig saw blade bends a little bit. But it is ok because the drum will be trued anyway.

Slow but good progress... :-)

Cheers Christoph

wow that looks really dangerous.
No router table and bearing pattern bit?

[falls]

That looks pretty rad
Rockler or others have an attachment for routers to cut cirlces
eg.

Might not have got down to the diamter you were looking for

[Jibber]

I didn't use a router because I hate MDF dust I saw a lot of picutres where people are doing exactly the same thing with a bandsaw so I thought it would also work with a jig saw. I finally cut all the 32 circles without an accident

Cheers, Christoph

It's a damn sight easier and safer to cut discs using a table saw.

Got 50m sanding paper on a roll yesterday. I think I have nearly everything to builld the thickness sander. I have built the first part of the frame today.

I am concernd if the core will stay in the planer (sander ;-)) crib because they are no rollers to push the material down in a thickness sander. Any ideas for simple DIY rollers? Or will the sanding drum push the core down...?

Cheers Christoph

PS: 100 points for all who have understood my gibberish.

you wont need rollers if you screw the core down against a nice flat and solid crib
i ve built some basic rollers with steel rods, skatebearings in a plywood case and spings from a desk lamp:

good luck

Thanks @ fa! How did you attach the sandpaper?

Actual progress:


I just have to screw everything together.

Cheers, Christoph

Your shop is so light and clean...and I have floor envy )

hey Christoph, nice job!

see the 3rd pic top-down at the link i 've posted above
the sandpaper's end goes through a slit cut at the drum's edge
then it is secured with a small beech wedge at the underside

kiteboards are wide, get the lowest grid you can
i use a 36 al ox for woodwork

is your core's outline inspired from 2010 North boards?
looking great, keep updating

Thanks for the help. My new shop is indeed really nice and just 10 meters away from the living room. Sometimes I think I am dreaming...

Is there a way to change the rotating direction of the motor. It is a normal 230V motor with 3 pins. Now the drum is pulling the wood inwards an this is very dangerous... (yes, I could feed it from the other side)

Cheers, Christoph

Clean shop indeed!

If it's a 1-phase AC motor - no. Mount it on the other side.
For 3-phase motors - switch two of the phases.

This is echoes from my pre, pre, previous career. Things might have happened....

I had no idea. That's straight up genius.

Not necessarily true. A lot of single phase 230v motors are reversible. Are you sure that all you have is 3 wires? You may have more than that and they are crimped or nutted together.
