Kobus,
I fit the whole Dremmel machine to the router. They are meant for smaller jobs though. I engrave the Rowmark material with this setup.

Something like this http://mechmate.com/forums/showthread.php?t=879

Kobus let your local postnet send a courier pick it up the same day next day at 12 it should be in Brakpan ( Berco express).Here is that cutter

Ok Hennie don't be so slow man, make me one or two of those things please. 6mm O/D and 3mm I/D. Wish I had a lathe....Groetnis

Are you going to use the dremel bits?if so arn`t they all 3.2 mm dia. 6MM o/d is a bit to thin to put a grub screw in.What is the max size of your collet 6mm ,8 mm, 12 mm.

Yes you are right again...3.2mm

I have 1/4 inch (6.35mm) a 6mm and 8mm collets on the little Makita.

So maybe a 8mm O/D will be better. I will send you a piece of 8mm round bar or do you prefer rebar....:D

Or if you can SPLIT the 6 mm length wise so that the big collet clamp the insert.

I will use the 8 mm keep your bar I will make a plan.

Baie baie dankie....moet ek hulle kom haal ?:)

Laat daai bakkie se neus Kaap toe wys,laat weet net wanneer.Gerald gaan julle nog diekant toe kom?

Ons ry oormôre.

I just jump on the bike and leave the baggage at home...:D

Sal nice wees om julle almal te sien

Jy lees nie reg nie..ek los die ou sak en kom alleen....grappie....nee gooi dit sommer in die pos asb.

Ek het reg gelees,ek doen dit army style ek hou net my mond:) is more by die werk winkel dan sal ek gou `n plan maak.

Just updated my V-Carve Pro V5 to the latest FREE upgrage. Wow I am impressed.....now to explain to the wife that I need that extra stepper and Gecko.... life is tough, but a man has to do what a man has to do.

Getting there. Progress on the bosses round table. Run out of my favourite waterbased varnish, but will give the legs some more once I receive the varnish....My local hardware has promised me for 2 day's now, but still no varnish. The boss is now putting on the little granite pieces into the 4 clovers. Thinking of some dark colour grouting between the pieces to go with the leaves on the border.

I am happy with the way that old BBB cut out the legs....slot into each half, one from the top and the other from the bottom...slid together like a glove. Had some issues with the legs breaking, so I sandwitched them with 4mm plywood. They will not break that I promise you.

The next table will be from proper wood...something like Kiaat..

My late dad was a carpenter / cabinet maker, but sadly he died when I was very young and I did not have the time to learn the tricks of the trade from him. I play around with making stuff for myself, but is not a good cabinet maker. I battle to make nice tight connections on the joints. I think the biggest problem is that I battle to sharpen my chissel properly...:rolleyes:

So I decided that old BBB must help in this regard...and since I am at home with some spare time it was time to play.

Made a jig that will hold the pieces with reference to a ZERO point on the same piece of MDF. Did the first cut, but it did not fit so well. Speed was set too high. Adjusted some settings and must say I am please with the result. Will try another type of joint later.

Kobus,

Nice joint. Which bit did you use to make it?

3mm straight cutter. Too short to go right through...will look for a LONG 3mm or 6mm sometime next year.

Kobus,

I like the way you have it now. It would make a strong joint.

Well I finished the round table today and in the same time did a 950mm x 290mm Hall Table from Cedar wood that I stained. Very happy with what old BBB do for me.

Very nice table , whats next?

Thanks Leo. I have also made a back massager during the table construction.

Attachment 7955

Here anything goes, I am trying my hand at different things so that one day when I really need to make money with old BBB, I know what my limitations are.

Decided to make another Hall Table. This time from Teak. The top part with all the flowers done at a very SLOW speed took 25 minutes with a V-cutter. Size of top is 1000 mm x 940 mm. Only one coat of boiled Lynseed Oil for now.

Pierre decided to wipe down his favourite chair with the lynseed oil rag that I used to do piece.

Will do the legs later this afternoon.

Table
 

Kobus ,that is a very fine looking table I like the flowers.

Hoezit Kobus!
A few questions on your Cedar Hall Table.
Did you only do the the flat pieces with Old BBB?
Was the legs done on a saw?
Did you dowel it together?

Groetnis
Johan

Hi Johan, Glad to see you are still alive. Hope the ribs and foot is all healed OK.
Yes all flat pieces done by old BBB. I planned to do the legs as well and started with that little groove on the top. That went well. Then decided to taper the leg and give it a ball at the bottom. The mortises went well, but when I started the taper, there was not enough meat left to keep the edges from splitting and tearing....but like my trappemaker friend in Hilversum Holland said....everybody makes mistakes, but if you can fix that mistake then you are not too bad.... I then took the legs with the mortices and little slots that were perfect and quickly build a taper jig and made the legs taper to cut away my boo-boo.
Next time I will use a bigger piece of wood for the leg and do all the cutting with old BBB.

Thanks for the info. It still surprises me what one can do with the machine.
Yes, my ribs are healed but it cramps sometimes. The ankle goes into a safety boot and that supports it. I have started to work on my machine again and will post pics soon.

Yes I think it is time to start that machine Johan.:)

Question to the experts out there. Will a Nema 23 stepper...something like the Fulling FL57STH76_3006B be good enough for an Indexer ? Maybe with a 3:1 belt gearbox ?

Gut feel tells me that Nema23 at 3:1 will work for workpiece diameter of 40mm max.

Thanks Gerald, sounds good...with the stuff that I intend making.

If I am prepared to work at a slower pace...like I do at my age....:D.maybe I can go a bit bigger in diameter...or do I have it wrong Gerald.

If the diameter gets big, the cutter will "backdrive" the indexer motor. In other words, the indexer motor will lose steps because the torque will be too high. The bigger the diameter, the bigger the torque needed to hold (or turn against the cutter).

A 5 to 1 works fairly well with a 450 oz Nema 23 . And you can go up to a larger Dia.

What diameters (inches/mm) are you talking Leo and how long is that Nema 23?

About 4 to 5" in Dia. The stepper is around 3.5" long not for sure,but I can take some measurements. Here is one to take a look at using the same thing
http://www.youtube.com/watch?v=oFC3lbLdzow Its not going to be a high production set up , but for a job every now and then it would work fine.

Fulling motors with 3:1 gearbox For peaple thats colour blind.
 

Attachment 8041the spec`s for the motor length is 76 mm

Leo, that is a great video. (To get the scale perspective, I think the cutter diameter is 1/4")

Nema 23 motors are available in different lengths, according to the number of magnetic stacks, ranging from 1 to 4 stacks. The output torque multiplies by about the number of stacks. From the video, I guess that Leo's motor is 3 stack, or a very soft wood and a 2 stack.

Gerald yes the cutter is .250". I think a guy named Thom made the vid and the machine, but I have the same setup as a 4th axis. You can run hardwoods at near that speed. Of coarse the MM could push this around with no problems at all. But this is a good cheap setup to test the waters and will work fairly well as long as you dont take too big of a step over. Programing 4th axis programs takes a little practice. Of coarse the software is getting better every year. You could always make your setup so you could upgrade the motor later, but a 4th axis gets old quick as with mine it is in several parts and is collecting dust. When it warms up I may mount it to the MM.
Just hate to see someone spend alot of money on a 4th axis and find out it is not all that great. And depending on what you make ,programs can be quiet long.

Leo for the DIY man with a MM and a 4th axis it is heaven think of all the things one can make for your house,yes i agree with you it is not easy to do the programing but once its done it is for keeps.I on the other hand are not going to get the 4th axis but will be converting one of my lathes to do my turning MM style. first the metal lathe and then the wood lathe.
