#10 Hook by Kristian
I've just made 3d of the hook,beam and finger.That you had are sketches and they aren't so well...and I made some upgrades that these details can produce.But I can't understand how you would produce the hook,at first I thought that it's from sheet metal but there is different thickness so it won't be from a sheet 2 mm thick.I suggest you would use 2mm metal sheet then cut out from back side 0.5 mm and then bend this outside part (4,5 mm high).... but it doesn't have any science. I'll post that what I've done.If you want to bend 1,5 mm thick and to faces to be align at 90 degree and you want to keep that rounds R2 and R0.75(they call fillets)you need at minimum R1,5 in the inner corner of bending that goes 1.5+0.75 = 2.25 the outer round and yours is 0.75.So I calculate where and how much to be cutout.I can't understand how did you expect to achieve that different thickness.About finger ,I add some chamfers and rounds(fillets) which are obligate for manufacturing.
I can make drawings (PDF)about a day.But I need to know what machinery will use(milling machine or something) so I can presume the technological operation.

And I suppose that you mean under "R4" and "R8" the diameter of the round of the hook?

By the way I need these drawings in a CAD form for submission to do prototype. But i have no means to see a CAd drawing, so you will have to send me a PDf as a proof so I can see it.

ON FINGER PULL. ( see new drawing FINGER PULL II)
a) the full length is 44mm.
b) the distance of the 1.5mm hole from the left edgee is : 8.5 mm.

For the GUIDE BEAM you now have the correction drawing named GUIDE BEAM II.
a) the size of these 2 holes should be 1.5 mm ( not 1.4 mm).
b) The top hole remain at 13 mm from bottom, but the lower hole is now at 9.5 mm from the bottom.

A) On the beam, the distances of these 2 holes have to be revised. My drawing is wrong. I will submit the revision this afternoon.
B) Hook,
Question 1: There is no 0.75 anywhere. If you mean the section at 45 degree it is 1.75 mm. I guess I do not know what is a "fillet". That base section with the 2 radius, ( R0.75 and R2.0) exist only at the bottom of the part.

Question 2 : It should be 8.4 mm ( 8.5 is wrong on my drawing).

Finger pull

There are 2 missing dims - total length of the part - you gave 14.5 mm from left side, 19 mm from right side, and the total distance is missing
the distance of the 1.5mm dia hole fro the left side

please update so I can finish and upload the design

1. what should be the fillet at the hook corner? in side view it is written 0.75, but on front view the line is 1.5 mm from the top surface. please check and confir, the right dim.
2. on the side view total hight is 8.5mm, but in front view it is 8.4. what is the right dim?

please check the distance of the 2 1.4 mm holse in the beam, its defined as 13 mm and 5.6 mm from bottom, meaning the distance is 7.4, and in the picture it looks less then 2 mm.

Please confirm the right distances between the holes

thanks

3D concept design of house to show roof configuration
We need someone to generate a 3D concept diagram for our current house design to show a change in roof design. We are changing from a mono-pitched roof (as per attached images) to either gabled roof design or a gabled and hip roof design. Note the top row of windows on the northern face will be lost in this new design). The main part of the house is to have a gabled roof. (This includes study, lounge, dining, kitchen, bed 1). This area will have vaulted/cathedral ceiling. Internal height of north facing side of the house will be 2.4metres - rising to 3.5metres in the centre of the main living area. All windows (bedroom and north facing sliding/stacker doors) will be 2.2metres high. Two designs are required. One design with wings 1 and 2 with a gable roof. The other design with wings 1 and 2 with a hip roof. Wing 1 = Bed 4, 3, 2, TV room and bathroom Wing 2 = Garage, linen and laundry. Example of style gabled roof design similar to http://blog.2modern.com/wp-content/uploads/2012/07/stinson1.jpg The external height of the roof is a maximum of 5.5m. External cladding will be dark grey - as per http://colorsteel-prod.imgix.net/assets/blocks/gallery/Hai-Nui-House-COLORSTEEL-ENDURA-Ironsand.jpg?auto=compress&fit=crop
