Chop Chop!!

Alright enough testing lets see some chips fly. From your vid it looks like you are on your way. Great job on the conversion.

Gerald D · #**603** Sat 16 January 2010, 11:22

Kobus, Hennie says he wants you to turn that into a chopstick.

sailfl · #**604** Sun 17 January 2010, 03:22

Kobus,

I recently learned that turners will cut the corners off before they start to help round off the piece. It is a faster process done on a table saw and helps reduce machine time.

The rounding Gadget in V-Carve Pro from Aspire takes a square piece of wood and quickly make it round...I like watching BBB working.

Here is a short video showing that with Vectric V-Carve - Pro it is really easy to do spirals and fluting...Even I managed to do it first time around.

The lathe is not fixed to the ground yet and also not levelled, but I could not wait to try it..

Breg Gat ! ek hou daarvan

Gerald D · #**607** Sun 17 January 2010, 11:01

Kobus, you make the whole subject of "indexers" look so darn easy!

Kobus_Joubert · #**608** Sun 17 January 2010, 13:06

KISS

I am too stupid to re-invent the wheel.

I am not hugging and kissing, just keeping it simple

domino11 · #**609** Sun 17 January 2010, 13:47

Nicely done Kobus! I definitely want an indexer!

mikefoged · #**610** Sun 17 January 2010, 16:52

really nice, I want one to..

Made this for fun, just to see how it's looks in blue

Lex · #**611** Sun 17 January 2010, 22:41

I think you find the next 'Gear' Kobus. Impressive.

Kobus_Joubert · #**612** Mon 18 January 2010, 01:01

Nice Mike I like the drawing. At the moment mine is bolted to the floor.

I have the following idea... Make a new shaft for that old lathe. This one a little longer than the original....16 mm up to the end.
Fit the old 3 way pulley on the shaft and connect the electric motor again.

Put my 120 tooth Module 1 gear at the end of this shaft after the pulley.

When I make spirals etc, use the stepper to drive the machine.
When I finish the piece (sanding or small steps that I did not get right with the CNC setup) run the electric motor. This will give me the SPEED to sand and polish the piece.

Also thinking of buying a 100mm taper lock pulley that will fit on the end and bolt my module 1 ...120 tooth gear onto this pulley. This will save some money as the engineering shops are mad with the price to cut a taper into my module 1 ...120 tooth gear.

Gerald D · #**613** Mon 18 January 2010, 01:22

Kobus, have a look for "weld-on" taperlock hubs. That type works with a key in the shaft.

Kobus_Joubert · #**614** Mon 18 January 2010, 02:16

Thank's Gerald. What is the best type ofsteel to get for a shaft....must be about 25mm then I will turn it off to 16mm on that side. Will mild steel bar work ?

Gerald D · #**615** Mon 18 January 2010, 03:22

Mild steel will work. Normally I would suggest you get EN8 which is slightly more expensive. But, nobody will sell you such a small bit and certify the grade - you will have to go scrounging and find a piece of unmarked steel in a scrap bin. So you aren't going to really know if it is EN3, 6, 8 or 24. Doesn't matter, you have a big diameter now.

Jan de Ruyter · #**616** Mon 18 January 2010, 09:14

Kobus, there is a company in Sebenza on the corner of Ingwe and Grader Rd that sells short pieces of EN grade steel. In Wadeville between Rossouw and Nagington there is a company that sells ground bar, which will be much less troublesome than mild steel.

Kobus_Joubert · #**617** Mon 18 January 2010, 12:15

Thank's Jan...Wadeville is close to my work.

I wanted to do this for a long long time. Now I did it. After bolting the lathe to the floor and setting up things to be level, I made my little piece. It is 3 flutes 150mm long.

I see I have a brand new heading...about time

mikefoged · #**618** Mon 18 January 2010, 12:31

kobus very nice, see that is what indexer do .

I was thinking about when you bolt the indexer to the floor it is not flexing with the Mechmate, is this a problem.

domino11 · #**619** Mon 18 January 2010, 12:39

Kobus,
Very nice, did you laminate the wood to get the interior hollow? I like it.

Kobus_Joubert · #**620** Mon 18 January 2010, 12:51

Hi Mike, I now find out that my table is not that solid. After using it for so long cutting X and Y, I did notice the table shake somewhat, but did not worry about it. Now with the indexer on the ground I can see the oscillations. As a temp. fix I wedged a piece of wood from the side to the wall. This weekend I plan to make some struts from the sides and bolt those to the floor. It was not causing problems, but I did not like the SHIVERS that old BBB showed....was worried he is getting old like me..

Heath, that is one solid piece of oak. I use a 6.35mm straight cutter and went in deeper and deeper. Set up V-carve pro to cut in 1.5mm steps up to 16.5mm. Then 0.8 mm deep cuts until I saw it cutting through....broke the first one when I tried to cut too deep too quickly. The twists are not that strong. At the end took a 12mm ballnose cutting a 3mm to finish the groove.

Regnar · #**621** Mon 18 January 2010, 19:35

Reminds me of the Legacy Wood Working Tool Demo! Looks great. If I remember correctly if you are able to move the tailstock up or down you can make tapered ornaments. I should go and check out their website before I start passing on bad info.

Lex · #**622** Mon 18 January 2010, 22:10

Very nice Kobus!
You make things complicated for me. There are a thousand more ideas from the wife side after she looked at your post.

hennie · #**623** Mon 18 January 2010, 22:35

Kobus I see it is another thing that you can cross of your bucket list.Baie mooi

The way Kobus is playing with his MM it won`t be long then he is going on retire right in front of BBB.

gixi · #**627** Tue 19 January 2010, 10:45

Kobus, now you become my model... Please, please make a video with this job !
I didn't forget what I promise but Gmail don't allow sending exe files.
I'll find a way to send you those files.
Marius

Kobus_Joubert · #**628** Tue 19 January 2010, 11:17

Ok Marius, will do sometime.
Tonight decided to try the OTHER available gadgets in the V-Carve Pro program.

Firstly...HI-TECH way of setting the Indexer on Zero... you must have noticed that extra wiring to proxies and limit switches and stop blocks are out for me.

DSC01008.JPG

Then did a 4 flute where I ramp in and out at the ends.

DSC01010.JPG

Then a single spiral LEFT and then a single spiral RIGHT

DSC01011.JPG

And finally. The words MECHMATE, KOBUS and ERWA on a cylinder.

MAGIC........

mikefoged · #**629** Tue 19 January 2010, 11:19

gixi just rename the file to .txt after the file name and kobus only have to rename it to .exe when he receive the file. easy

domino11 · #**630** Tue 19 January 2010, 12:29

Kobus, enough already, that just looks like too much fun!
