Photo is a bit small, looks more like Oak to me, that style of chair was usually done in Oak. Did you copy the carving on the back panel as well - that will be easy to produce with your Aspire I would imagine :)

Thank's for the input Allan. I thought that it could be Maple as it looks like the Flamed Maple I ordered for my violin. Yes the back piece is EASY to do with Aspire.
It does not look like the Oak that I have available right now.

Looking at the fleck on the side of that arm, now convinced its Oak - the reason it does not look like the Oak you have now - because we dont get good Oak like that any more. Maple is much lighter in colour with not as big a difference between early and late wood (grain pattern).

Kobus_Joubert Mon 07 February 2011 12:16

Thank's Alan. So this is REAL wood.....;)
Was a pleasure to work with...got a nice finish with furniture scrapers....did finish it with 3 coats of Woodoc-10 with Oak tint. Customer came to pick it up tonight...was very happy.

That looks like quarter sawn oak to me. Here in the states quarter sawn oak is very desirable.

English oak

At least I know what this is.....SABIE YELLOWOOD..aka pine...:D

Got an order to make 4 legs 860mm high...she did not want any 3D on it :mad:

But the customer is ALWAYS right.

Especially if they are paying :)

Looking good.

hennie Sun 13 February 2011 09:39

nice Kobus how long did it take?

Kobus_Joubert Sun 13 February 2011 10:04

When I did my first 3d leg it took nearly 2 hours for roughing and 2 hours for final cut.
As I progress with Aspire and use the different tools in Aspire and because my indexer is dual purpose ( stepper and electric motors ) I brought it down to about 34 minutes for roughing and 34 minutes for final cutting. Just more than one hour per leg I would say....then some sanding.
Want to bring the time per leg down further.

Kobus,
Was that done with the circular saw heador the router? Have you tried the lathe mode with the router?

Nice work! :)

Kobus_Joubert Sun 13 February 2011 22:05

This still with the router. I think I can speed up the process on turned stuff without 3D by using my little saw.:p
I have tried the lathe mode with the router long time ago before Aspire and 2 rail sweep.
At that time is was not working well, might give it another go. But remember the sawblade is only 2mm wide and the router bit is anything from 3 to 6mm.

javeria Mon 14 February 2011 00:14

Kobus - don't underestimate the sawblade - I am building one machine which I will post pics of soon with the saw blade and its fast - real fast (like the one JR had built)

and then watch this video on youtube http://www.youtube.com/watch?v=EWyZCWkpLcI

Jan de Ruyter Mon 14 February 2011 11:08

Kobus,

My 2c worth: a saw blade is designed to cut radially. If you put it in a lathe, you are forcing it to cut on the side of the blade. If you speak to our friends at Leuco or Austro, they might have a special blade for an application like yours. This will considerably increase your cutting speed.

Kobus_Joubert Mon 14 February 2011 11:37

Thank's Irfan...pity the video is so bad. Would like to see what his blade looks like.
Thank's Jan will check with them. When I did the first runs on that thing of mine I did notice that the blade is moaning a bit, but I slowed the feed speed down and it was ok, but then again the overall time of cutting goes up.

hennie Tue 15 February 2011 00:29

Kobus I had a talk with a contact. Yellow wood R 2500 a cube The real thing

smreish Tue 15 February 2011 04:56

I have personally used the 4.5" (100mm) diameter wood carving blade designed for side/front gullet cutting in this application. works very well and quick.

Kobus_Joubert Tue 15 February 2011 05:02

Sean is that the WOODCARVING blade you can fit on a baby angle grinder? This is what I am looking at using now. I have one for Power Carving...a bit wide (3mm I think ) but will give it a try.

Ok Hennie when are you comming up with your truck ?;)

smreish Tue 15 February 2011 06:57

Yep, that's the one Kobus. It is a bit wide, but when I need a really narrow profile, I use a slot cutting mill disk from by bridgeport metal milling which can handle the side load on the gullets.

I'll be honest, I haven't done this in about 5 years, but it worked great then.

I also used that wood carving disk, on a baby angle grinder, on my MM Z-axis to reproduce that WAVE pattern board that Gerald and Sean designed so many years ago. IT worked really well, but getting the toolpath to step-and-repeat so all the panels could be used end-to-end was a bugger!

Jan de Ruyter Tue 15 February 2011 10:34

Kobus,
The guys from Leuco sell a hogger. Seems to be the right thing for you. It cuts radially and laterally.

javeria Tue 15 February 2011 10:48

Jan whats a Hogger

Jan de Ruyter Tue 15 February 2011 12:15

Ma'a salama!

Kobus_Joubert Tue 15 February 2011 12:23

Jan that LOOKS very very EXPENSIVE:eek:

Alan_c Tue 15 February 2011 14:21

It's from Leuco... it will be :)

Jan de Ruyter Tue 15 February 2011 22:03

Well, if you don't ask, you will never know. If you have to ask, you can't afford.

Dammed if you do, dammed if you don't.

I've used Leuco blades for many years, resharpened them often and always had good service.

Kobus_Joubert Tue 15 February 2011 22:16

I think old EL-CHEAPO me will first try my wood carving angle grinder blade that I already have before being dissapointed with a Leuco price.

Had to do a small oval thing for an old lady. Had to be a St Joseph lily.
Found a nice one at http://www.3dmodelclub.com/cmsj15/ must say the quality of the final product was amazing...even on a small size like this.
Attachment 11299


Also busy with my PORTABLE CNC... pity it is not a MM, but I needed one that is small enough to take to my woodworkers association. As I am the South African agent for UIM Robot stepper drivers, I might just build a few for sale. Already a few members are showing interest.
Attachment 11300

Note..the wooden parts are just for getting it all sorted..As I cannot design in CAD, I build it this way, and will then have the parts made by a Laser Cutter.

hennie Sun 20 February 2011 02:03

Waar het jy die rail blocks gekry?

Kobus_Joubert Sun 20 February 2011 08:16

He he he... my geheim. Hoeveel soek jy.. 20mm ok ? Praat net, ek het mos 'n besigheid :D
