Done

-- Thehunter (talk) 11:02, 7 April 2021 (CEST)

the material specifications "steel metal" are too unspecific, I assume that "steel A36" should be used for these components, is that correct?

Re: -- Inddigital (talk) 17:23, 9 April 2021 (CEST)

Resolved

Part number 2.1 -- Thehunter (talk) 11:10, 7 April 2021 (CEST)

The belt guard consists of several components, the perimeter plate and the cover plate. In the case of the cover plate, it must be specified whether it is to be a finished perforated plate (perforated plate). In addition, information is missing on the minimum and maximum diameter of the holes, as well as information on what percentage of the area of the cover plate is to be perforated. However, this information is not mandatory because the belt guard is not a critical component.

Re: Part number 2.1 -- Inddigital (talk) 17:26, 9 April 2021 (CEST)

Ok, the corresponding annotation has been added

Part number 3.8 -- Thehunter (talk) 11:13, 7 April 2021 (CEST)

I assume that the ball bearing is pressed into the tube 3.3 and not further fixed, is that correct?

Re: Part number 3.8 -- Inddigital (talk) 17:34, 9 April 2021 (CEST)

Right

Part number 3.2 -- Thehunter (talk) 11:15, 7 April 2021 (CEST)

Are these headstock bearing caps firmly connected to the tube 3.3? If this is correct how are they fixed?

Re: Part number 3.2 -- Inddigital (talk) 17:28, 9 April 2021 (CEST)

By matching the internal and external diameters, a tight fit is guaranteed, however, this can be improved by adding set screws in an improved version.

Part number 3.5 -- Thehunter (talk) 11:16, 7 April 2021 (CEST)

I believe that custom manufacturing of this component can be quite expensive, it would be better to select a standard pulley.

Re: Part number 3.5 -- Inddigital (talk) 17:30, 9 April 2021 (CEST)

Ok, I could evaluate costs and verify that the required diameters can be easily located.

Part number 3.7 -- Thehunter (talk) 11:18, 7 April 2021 (CEST)

Would it perhaps be better to provide the tapered area of this component with notches to ensure reliable power transmission and prevent the component from slipping on the drive axle?

Re: Part number 3.7 -- Inddigital (talk) 17:32, 9 April 2021 (CEST)

The thread must be in such a way that it does not loosen with the operation of the equipment, but the observation is valid and facilitates the manufacturing process.

Part number 4.3 -- Thehunter (talk) 11:22, 7 April 2021 (CEST)

ready-made tappet tensioners can also be used here, such as at https://www.boie.de/mechanik/normelemente/spanner-mit-exzenter-oder-keil/exzenterspanner/gn-927-3-exzenterspanner-mit-schraube-hebel-stahl/927-3-101-m8-40-b-zid10571657

Re: Part number 4.3 -- Inddigital (talk) 17:35, 9 April 2021 (CEST)

Nice addition for an upgraded version, doesn't seem to be an expensive accessory.

Part number 5.4 -- Thehunter (talk) 11:25, 7 April 2021 (CEST)

which diameter, which pitch?

Part number 5.5 -- Thehunter (talk) 11:27, 7 April 2021 (CEST)

I can imagine that depending on the speed of rotation of the machine, the friction of this component on the threaded rod generates a lot of heat

Re: Part number 5.5 -- Inddigital (talk) 17:36, 9 April 2021 (CEST)

Yes, this aspect should be improved with a sliding tip.

Part number 5.4 -- Thehunter (talk) 11:29, 7 April 2021 (CEST)

sorry, had not seen that the dimensions are on the plans, my mistake

Re: Part number 5.4 -- Inddigital (talk) 17:35, 9 April 2021 (CEST)

No problem

Part number 8 -- Thehunter (talk) 13:07, 7 April 2021 (CEST)

Typical spindle speeds for woodturning machines are 810, 1180, 1700 and 2480 rpm. Typical power consumption for smaller woodturning machines is 400-600 watts. The typical speeds of AC motors also vary. Therefore, the optimal combination of upper ring pulley, lower belt pulley and motor must be considered individually for each project.

Re: Part number 8 -- Inddigital (talk) 17:40, 9 April 2021 (CEST)

Ok, that might make pulley fabrication easier and speed up motor selection, although it might take away some flexibility to operate with different types of wood and finishes that require different speeds and torques.

Part number 8 -- Thehunter (talk) 13:08, 7 April 2021 (CEST)

To make the parts list complete, you could also add the pulleys, the one-off switch, the protection fuse and the wiring, but that goes without saying.

Re: Part number 8 -- Inddigital (talk) 17:42, 9 April 2021 (CEST)

Agreed, these elements can be added in a more complete version of the project.

-- Xtech2020 review (talk) 22:35, 7 April 2021 (CEST)

Will the equipment be stable enough to stand firm and vibration free? consider fixing the structure to the ground.

Re: -- Inddigital (talk) 17:24, 9 April 2021 (CEST)

I had not taken it into account, since it was intended for small parts and the structure already has a certain weight, but it is a good point for an improved version.

Part number 1.13 -- Xtech2020 review (talk) 22:41, 7 April 2021 (CEST)

can this part support the weight of the motor under operating conditions? 3 mm is somewhat robust but has some stress concentrators.

Re: Part number 1.13 -- Inddigital (talk) 17:25, 9 April 2021 (CEST)

It is possible that the motor has a significant weight, a reinforcement can be added to this part in an upgraded version.

Part number 5.5 -- Xtech2020 review (talk) 23:01, 7 April 2021 (CEST)

This piece should be free to rotate around its axis, since its function is only to exert pressure in the axial direction, without slowing down the rotation, unless it slides against the wood, which can affect the process.

Re: Part number 5.5 -- Inddigital (talk) 17:37, 9 April 2021 (CEST)

Correct, it is an aspect to be improved

Part number 3.7 -- Xtech2020 review (talk) 23:10, 7 April 2021 (CEST)

This piece is the one that transmits the rotational movement to the wood, a different tip could be considered, since friction alone may not be enough.

Re: Part number 3.7 -- Inddigital (talk) 17:33, 9 April 2021 (CEST)

Ok, I could think about adapting a mandrel to accommodate tips that engage the wood piece, in an improved version.
