Routing the flexible dust hose
Gerald,
Any ideas on how to handle the dust extractor tube. With the table being large it poses a bit of a problem. The dust collector is situated next to the machine midways. The tube is 100mm in diameter. I was thinking of a swing arm with a roller track.:confused: |
A swing arm with a track under it, and one or two runners supporting the hose, seems to be the best option.

Gerald,
Should I make the swing arm to reach the furthest corner? If not, what is the practice? |
I don't know of standard practice because I havn't seen enough systems. I think the biggest factor is the amount of ceiling height you have above the table. If you have plenty of height, you don't even need a swing arm. . . .
Note that it helps to support the hose above the z-axis so that it can drop down to a flexible loop after the support. Here is a fixed arm, again going to point high above the z-axis. There is no harm in building a swinging arm that stops about a meter short from the furthest corner - you can always cut it shorter later. |
The area that the machine will work for the first 8 months or so has a very low roof. I will have to go for the swing arm system.

This is the idea I am working on. I propose to use lazy susan type bearings at the pivoting points (so that the dust pipe can pass through it) I also have a very low roof over my machine. The counterweight on the top section is to balance the long section over the machine. The whole assembly must be firmly attached to a wall or steel column. The lengths of the two sections are critical and decided by the position of the fixing point relative to the table. The arm must always have a bend in it (when viewed from above) so that the assembly will fold correctly when the gantry moves to the back.

For very low headroom, there are a couple of guys who strap their dust hoses onto the edges of their cable chains.

Thanks for the replies gentlemen, it has given me some good ideas. Due to space constraints, I will have to go for the folded arm idea. I will show pictures later.
