Bill,

Thanks for sharing the 4X Gear Set info. with us. I'd seen pics of the gear set - but never the assembly instructions.

They indicate to me that someone at the Legacy Mill design department was a "student" of Rube Goldberg's "College of Engineering"! (It may now be a University. Maybe NY Joe can answer that one. I think he is an alumnus. He has THE Best engineering mind and skills!)

Since the "Subject" of most of the recent posts are 4X Gear Set related, I changed the Subject to reflect that. That way, anyone searching the files for 4X related discussions will find this thread. I hope you concur.

Have a Wonderful Wednesday!

Mac

I did not keep all the measurements I did for the other guy and there was very many I would have to remeasure everything again

All the sets of gears the linkages, ‘shafts many things I was hoping the member might offer to post them for you himself but I guess he is not there

I can remeasure but it will take a long time to do there is a great many parts have a look at the assembly instructions to give you an idea

Hi Bill.

Can you give me the measurements from Your set?

Arkady from Ukraine.

One of the members on here was going to get a set made i don’t know how that is going i have not heard back from him in a while, i gave him the measurements from my set. Very hard to find the 4x but here is a picture to show you what they look like

Some of the larger mills came out with the 4x gears on them but i don’t know which. there are a few other members who want a set too if the guy making his would make more sets he defiantly will get sales I believe.

Do you think it is possible to find this 4X gears set or make a copy of it ? I feel it is a must when you have a LOM 1800 for columns.

I feel the more extented is a spiral the nicer it looks.

Ps i just relooked at your pic the spiral only goes ¼ turn so that means a even larger pitch like 120 inch pitch which is the largest pitch the 4X gears do

If you have the 2X multiplier gear set the largest pitch you will get will be 15inches which on a 6x6 veranda post would not look like the pic you first showed it would be much tighter looking spiral. I think the spiral to look like the pic it needs to rotate 1 turn for the length of the spiral which is about 1/3 the length of the whole post, this is just a guess by me so you would need like 40 inch pitch for a 12ft post. You will need the 4X gear set to achieve this which not many of us have. Another problem is the 1800 if i remember will only reach 8foot long so that would mean around 30inch pitch. but you can get a longer post by joining 2 to get the length a practice used on the mill to sometimes get long work. like on a 6X6 post say a 2inch hole and 2 inch dowel glued.

Lots of things to think about. I was going to do this stuff once and looked into it. Something else to look at is round spirals on a square posts which i like better magnate make a 3piece router bit set just for doing large rope or barley spirals. Great fun the large stuff i love doing it. Ask Curt he wants to one day do a 60 ft spiral wasn’t that it curt.

Hi Curt, I will take the longest pitch to practice. For the post, I will have to chose the pitch according to the length of the twist I guess.

1/4 or a rotation on a 24 inches length more or less.

Hello Guy's! Sorry to be a late comer to this topic.

Emmanuel everyone has given you some good advice on this topic.

start with something you do not mind if you make a mistake on ... (scrap wood. or green wood. or at least something cheep.)

Set the LONGEST pitch you can set on your machine. and Make lots of light cuts. nibble your way down to the finish size.

Here is a picture of a cup I made using a banksta pod.

Anything is possible,

I wish you luck on your project.

Emmanuel,

Where the "corners" of the flats on the two ends meet up with the "corners" at the beginning/end of the Ribbon Twist, they will be the same. However, once you start the Flat Ribbon twisting about the axis, you should see that the 4 corners of the "Twisting" will end up beyond the flat faces on either end. Looking at your sketch - If the 5 5/8" is the correct measurement for stock that starts out as an 8x8, you will see that once the two ends are milled down to 5 5/8" square and you begin milling the Flat Ribbon, the "corners" of the Ribbon will extend above a plane that bridges between the flats on either end of the stock by approximately 1 5/16" at their apogee.

I hope I have not confused you and the issue.

Turn safely.

Mac

You are right Mac. In fact the post is 6x6 before milling. So I am a bit confused. If I want the twisted section to look like the picture twisted post.JPG ... width of strait and twisted faces seems to be equal on the picture. Optical illusion?

That's correct.

I knew you'd discover that - that your starting stock would have to be considerably larger than your desired end state size - as soon as you started milling the 1.5 re right " piece.

I just didn't know the exact amount you'd have to add. Again, once you do a piece in pine that's 8 1/2" x 8 1/2", you will find out how well that size worked to yield the finished dimension you seek.

That brings up a question: Do you HAVE TO HAVE a final size of 6x6 - or do you have a piece of 6x6 and you want to make the largest 4-side flat ribbon turning from it that you can? HUGE difference - as you have already seen. If you need to start with a larger piece, why bother getting one that's been squared up? Instead, see if you can source a maple "log" (round) that's a tad larger than the diameter you will need to start with. No sense in wasting money & time buying a squared up stock only to then spend time turning it into a round.

Practice, practice, and PRACTICE!

Best of luck. We all look forward to seeing photos of the various "practice pieces" you create - as well as the Final piece.

Thank you Mac! I will definitly practice on inexpensive pine before.

I also realised that to mill a 6x6 square spiral post you need to have a rough block of 8 1/8 x 8 1/2 as shown heretwist (1).pdf

Emmanuel,

As Curtis would advise: DO NOT "try" this (the ribbon cut) on your piece of maple - UNTIL you have tried it AT LEAST ONCE on an inexpensive piece of 6x6.

If you can't find an inexpensive piece that size - make one by gluing up several pieces of pine or basswood.

Personally, I recommend you actually start with a piece of 1.5" x 1.5" pine (inexpensive) and experiment to get a feel for the basic technique (like Bill was describing).

Then, once you are comfortable doing it on a full length piece of the 1.5" stock, try it on a full sized length of 4x4 pine. Again, you might encounter a glitch or two when milling this piece - but that's why you are using pine instead of your maple.

Then, once you have done a 4x4 with no "issues", give it a go on a 6x6 length of pine. Be sure to pay attention to grain orientation when milling this piece - then apply the lesson learned when milling the piece of maple. When you get that piece done to your liking, then - and ONLY THEN, chuck up you piece of maple and knock out your 6x6 piece.

Like several folks here usually promote: "PRACTICE - makes (close to) Perfect!" So practice until you can knock it out of the park.

Best of luck!

Mac

No its done with a long strait bit cutting from the side not from the top like the bit in your pic

There is stuff about cutting a ribbon twist spiral in the archives of this group it explains a 2 start, but to cut a 4 start you rotate the work 90 degrees instead or 180 after cutting each spiral

https://groups.google.com/ forum/#!searchin/legacy- ornamental-mills/ribbon$ 20twist%7Csort:date/legacy- ornamental-mills/xZDhgrJGKwU/ 2hqIhd3aGwAJ

A 6 inch square 4 start ribbon twist spiral your strait or spiral cutter will need to be 6 inches long dia doesn’t matter as your cutting from the side not sure where to get a strait bit that long and it would take several passes it would take time to do

Anybody else know a easier or better way speak up it might be possible to do cutting from the top but i have not done it i would have to experiment and see if its possible

Thank you Bill. Post is a 6x6 hard maple. I will have to make several passes to plan 6 inches wide for the ribbon spiral faces.

Would you use a 1/2 long spiral bit and plunge the router or a wide knif (3 in) like the one like on the picture and move the router on the axis ?

Yes that’s a 4 start ribbon spiral its done with a long strait bit from the side and your post is no longer than the mills 96” length
