Thickness sander


Recommended Posts

I’ve never used Syren billets or sheets, but generally use the Byrnes thickness sander  as a step prior to ripping sheets on my Byrnes saw, not after.   
 

Based on Syrens own description of their products, I assume they will come ready to rip without needing an additional thinning unless you need a specific dimension not offered.

It all depends on the wood species, grain direction, blade sharpness, rejection criteria and your cutting technique as to how many planks will be acceptable after ripping. I think the sander is invaluable for saving a bunch of planking that would have been rejected if ripping only.....

For scale sized planks, thickness sander alone should be fine.  I have the Byrnes, and before that used a Preac (same idea, much smaller motor).  I haven't had any times with pear, boxwood, holly, cherry, or ebony where the thickness sander didn't get me to a usable billet.  I have a tool buying addiction and haven't come up with any  reason to justify buying the miniature planer.

Because of minimum feed thickness of a thickness planer, feeding woodsheet less than 6mm (most of portable thickness planers) or 3mm (the Proxxon DH40) can cause serious kickback injury. I prefer the Byrnes thickness sander for the reason. Not aggressive, quiet, manual feeding, and precision height adjustment.

I also have a Byrnes thickness sander along with an Proxxon Table saw.

Yes for me, the thickness sander is a truly valuable tool. Waiting for the day when to invest in a Byrnes table saw.

Hi.

Exist there (in continental Europe) any alternative to Byrnes thickness sander?

I was given a Proxxon table saw - OK that was free. But we can't  find suitable small 230V drum thickness sander sold in EU.

 

Thank you for the advice, Radek

There is always the option to build your own.

Were you in the US, I would say that this option would probably not be less expensive than a Byrnes sander when all factors are summed.

 

The key factors:

Go quality.

Use a large enough motor.   1/3 HP is the sweet spot. 1/2 HP tends to be heavy and bulky.

A reversible motor is NOT needed.  Unless you also want it to be a medieval siege engine. 

DO NOT enclose the motor!  Sanding is a lot of work for a motor.  Work = heat.  As much air flow as possible!

The drum holding the sanding medium needs to have a large enough diameter - somewhere around 3 inches - before the medium was available as continuous cloth backed rolls, the width of commercial sanding sheets set the diameter.

added:  The drum speed should be ~1700 rpm -  faster and the wood burns - slower is slower -

that is a common speed for 1/3 HP motors and 1:1 on pulleys is easy.

Having a mechanical grip on the roll is way more convenient than using an adhesive to hold the medium.

A dead flat table that stays that way is absolutely necessary.

A reliable and micro adjustable gap set and hold mechanism is a must.

A dust extraction hood is absolutely needed, but no big deal.  I made mine using three layers of Amazon box cardboard, liberal PVA between the layers, 1/4" square internal corner braces, and duct tape. 

A kludge sander will sort of work for a time, but will ultimately be a source of frustration.

Thank you for the detailed description.

Honestly said - I've tried to build one inspired by Youtube.

(And read these topics:

https://modelshipworld.com/topic/25374-a-diy-thickness-sander/

https://modelshipworld.com/topic/26329-thickness-sander-questions/ )

 

My machine has an acu screwdriver instead of motor - 1st mistake.

Its drum is about 2 inches - second one. Etc., etc. 

 

So I wrote to Jim Byrnes and I'm looking for factory made sander.

Radek, I think Byrnes thickness sander is available for 220/240 V, just like the saw.
