Looks great.

I've just come to see your message !

All my apologies for this issue please find the PDF files attached

wishing you a good manufacturing, Alex

I am having trouble with the files sent. The pdf reads 0kb, no content, unable to open. How do I get a cutting list?

Thanks again.

Please find you files attached,

Kind regards, Alex

Thank you.

In the attached file, I have made a slight adjustment to the market penetration, but there are no other concerns,

If you agree, I will send you the documents.

Kind regards, Alex

A quick note: the staircase you upload already has a 30mm penetration between the step and the stringboard. 20/15mm is sufficient and easy to mill and assemble.

Cheers, Alex

I think I'll stick to simple, straight for my first stairway. I think I've made the changes you suggested. I made changes to step penetration to newel posts, as it may allow easier assembly, sliding in. Depth could be altered to match stringer penetration.

Would this plan work?

Cheers,

Derek

This may also depend on your installation solution. I think that stringers and curved handrails are more comfortable, but there is also the alternative of using straight per parts and subtly softening them.

-In files joint, I can't see the correction for penetration

-In curved mode, handrail have different dimension from others ( Right handrail 2 - 62*42 instead of 42*62)

as it is wider than the stringboard, it will have to be offset by half a thickness to bring it back into line with the stringboard.

All the best, Alex

I had not thought as far as penetration of risers, and the values used for penetration  were arbitrary. Thank you for the correct values. I have made corrections in the plan. I was planning on constructing the steps as the 3 flights separately, then fitting them together.

I did the design with curved strings and bannisters as an alternative, but seemed complicated and didn't look like a comfortable walk. What would your opinion be? 

Thanks again.

Derek

Your staircase seems coherent,

If we understand correctly, the left-hand side of flights 2 and 3 is against the walls?

Penetration can be reduced, the standard rules for joinery are 1/3 the thickness of the stringers, but not less than 10 mm.

I can't see the riser penetration into step, is it to simplify assembly?

Cheers, Alex

I need to build a staircase in my home. I am planning to use structural plywood/laminated. F17 grade pine 25mm thickness laminated to working thickness of 50mm, cut from 1200mmx2400mm board. Newel posts will be 90mmx90mm pine., To make it simple I have kept all stringboards straight. 

Please view my attached file and give advice on any changes which should be made.

Thanks,

Derek

There is no need to send anything. I was glad to help you out ;-). Actually, I am based in Belgium.

Thank you so much for your help.I am sorry for any inconveniences caused.  Unfortunately its like a new driver trying to drive a brand new vehicle, there is no substitute for experience gained.

I would like to send you something for your help are you based in the Henley Office?

Kind regards
