Looks like the Asian Method, European way!

Worth noting how he picks up the reference points on site, which is important.

Cheers

You're not bothering to actually look and read what I've written

Follow what oldboy22 is trying to help you with, or if you know better just get on with it. I'd take his advice if I were you Rodger, he seems to be very capable.

Meccarroll

My reasoning for dropping those vertical lines at X X are correct, I've decided. However, drawing either a central vertical line (as per di Cristina page 132) or even a centre point on the face is not necessary providing that you use commonsense and position the top template to allow for the extra ...

oldboy22, I have a very simple way of obtaining the bevels for wreathes but I would like another as a double check I have read about other ways of obtaining the bevels but they are complicated so I have to admit I am not found of them. Your method looks quite like it may be easy and quick, is there...

Looking at Plate 70 page 132, the line O-O looks to be on a slant. Is that correct (I think it is and is there by virtue of sliding the face mould) ? Sorry for the late reply Rodger I've been at work. You are correct. If you stand the wreath in an upright position as it will be when fit to the stai...

.... I am applying the methodology of W & A Mowat which uses the minor axis to determine the crossover points for the wreath and from that point I was going to use a series of diminishing vertical marks from where the twist starts and then finish at the point of minor axis. .... I'm misunderstandin...

Meccarroll

Meccarroll If you follow my previous advices and work the new vertical surfaces first it’s easier to hold in the vice, two parallel surfaces to grip. I was aware of that sides come first oldboy22 . If you then cut a piece of paper or thin card the thickness of the rail and long enough, you can lay ...

Meccarroll

Photos are always good to help with this sort of question. Don't be afraid to do a proper job. The screws might be stuck which might mean you have to spend more time on the repair than you would like but that should not cloud your judgement. As you have pointed out there are children involved so eve...

Meccarroll

Here's a few photos, Mark. I can see the advantage now of a ply template. Do transfer all of the relevant markings to the template including the Tangent lines and Minor Axis as this will allow you to use the Minor Axis as a reference point when lining up and cutting the wreath. Thin ply/MDF templat...

Meccarroll How’s it going ? Had a chance to have a go at it yet, I’m looking forward to seeing it . Hope you took/ take some stage photos. I have been doing the garden, tidying the garage and making an ellipse jig so not had time to take things any further. My CAD programme is quite dated and a bit...

Meccarroll

That looks really good Rodger, in fact Bl..dy Brilliant!

You are moving leaps and bounds now.

This is the hardest part of the handrail so moving on to the Volute and lower Wreath should prove much easier to do.

Meccarroll

Wow Rodger that's great to see. If you gave this project to most carpenters or joinery specialists they would run a mile and I mean the real ones not the clowns that claim to be professionals. Most good joinery shops can make stairs and do circular work but I have never personally come across any lo...

Meccarroll

It's so hard getting that twist out of the wood. Making sure that you're gradually rotating the faces. Any tips ? 1. Make a board stand on edge vertically near to the bandsaw blade so you can use it to rest the Wreath on wile you do the cuts. Round over the top edge of the board so the wreath slide...

Meccarroll

Thinking on it I’ve made a cockup you should add a straight bit to both ends and reduce the easing by that amount , I don’t know why I drew it like that but I did. You don’t put a straight bit where one twist joins another twist ,but of course the easing isn’t twisted . :oops: That's what SCMS's ar...

My latest Drawing of Rodgers Quarter Turn, re drawn because my Cad Programme seems to think kindly of wiping my saved files into oblivion for no reason!!! Rodger wreath.jpg Fortunately I managed to print the wreath out before it disappeared so I stand a chance of testing the results of my drawing.

This all seems to be moving along nicely, I do hope all goes well.

Here’s a different technique to draw the ellipse, this is what I used to work out the handrail in my staircase (first page), I didn’t really understand it at the time but it worked, I didn’t have as many books or as much knowledge back then. That seems to follows the same method used by Mowat Fig. ...

Meccarroll

OK...I'm having one more crack at this. I revisited my drawing and although I had intended to pick up the different widths of the ellipse at either end and had done so, I'd used the wrong reference markers - which is why Oldboy thought they were parallel (they're not but marginally...hence the conf...

Meccarroll

Question: Why do you suppose the minor axis is not correctly positioned? I thought I followed the book or to be more precise where did I deviate? The end of the ellipse at Q is wider than at P so there is a deviation in the points of the ellipse. I think that may be an important point that I have o...

Meccarroll

On closer look I think I notice you don’t have the minor axis point correct, if the rectangle is supposed to be the centre line of the ellipse the radius used should be to the centre line of the ellipse, if so that makes your spring lines out. I also think something is out but not quite sure what s...

Meccarroll

PS: oldboy22, If I have missed any points you raised it's because I am now winding down for the day but appreciate your input and will look to answer then asp! In the mean time Take care.

Meccarroll

This is where I am at at the moment. I am having a bit of trouble forming the ellipse with my CAD software Rodger Drawing.jpg (1) Very good although a little busy it’s hard to pick out the the important bits, I love the way you’ve used Mowatt to develop the upper tangent but you have also used the ...

This is where I am at at the moment. I am having a bit of trouble forming the ellipse with my CAD software (TurboCad 4 for Mac). Because the ellipse is on an angle and the programme does not seem to like working other than horizontal or vertical. I have used it in the past to perform ellipses for wr...

[ The drawing for Rodgers stairs should come out similar to mine if you follow the same dimensions depending on you development process. I am working from a stretch-out which is the product of the riser and going dimensions Rodger gave to me. From the actual stair dimensions I am producing the draw...

I'm working on the easing today. The Asian approach comes later.

Keen to see the next stage, any updates Rodger?

Meccarroll

If those first practice pieces were made 35 - 40 years ago and you made the set of stairs 15 years ago you have spent a long time learning tangent hand-railing. What was the material used to form the curve for the strings? I see a lot of this work done in ply then covered with veneer but some use s...

Meccarroll

Hi Rodger, I know you are moving away from the Tangent system but the drawing below is what I would call a Stretch Out of your stairs. It is essentially the stairs folded out at the corner as if on a hinge at the corner so you can see each elevation side by side. The pitch lines are shown for both t...

Meccarroll

That's a nice start but maybe a new thread? It may be difficult for people to visualise what you are conveying without a wreath section. Without adding a typical application for the drawing it may be difficult to visualise the relevance of such work. Which book are you working from Oldboy22, and ca...

I've been finding this really interesting to follow along

Don't be afraid to chip in, it is hoped you will!

Meccarroll

I can't disagree with anything that you've said, Mark. FYI..the lines on the underside are historical. The actual tangent line is marked on the top surface. But even this one shows that, were it correct then cutting the face at a right-angle to it would not butt up with the upper handrail. I take y...

Meccarroll

You have managed to create a very interesting thread here Rodger. I am totally hooked! It’s going to keep you entertained a long time if it carries on like this. Most people spend years learning this stuff and Rodger has come an awful long way (with your help) in a very short space of time, I hope ...

Meccarroll

That's the camera angle, Mark. I had the laser line on the 'extension' and it's all square. The line on your paper next to the letter "B" is the tangent line. The end of the wreath must be squared off to that line (Tangent Line) and your picture shows this to be true. You have added a wedge of poly...

Meccarroll

It looks like you have decided to manage this with a bit of fettling. What you have been doing in the other thread is beyond my current capabilities, I have only managed wreathes which have the same pitch and although not easy to do I would say they are relatively easy in comparison to your quarter ...

Meccarroll

Here’s my version with your dimensions?. What do you think, are the dimensions correct. That looks really good. I'm optimistic ! I think the fruits of this discussion are down to a good teacher (Oldboy22) and student who is determined to learn(thatsnotafestool). Looking forward to seeing the mock up.
