Workbench gas spring By Pierre on 16 Dec 16:09

When I work on a drafting table, the most annoying is the speed of adjustment, having to turn the wheel for a long time before finding the right position. it's very important.

had to keep the same design. very few holes, very little installation time.

At first I removed the gear system. and using a spring. but we must block the table height and the system must withstand 500kg

Why not a gas spring? ok but still have problems to lock up. I tried a system of rack and rod, but it's the same thing, too fragile.

and after researching, I finally found it ! Lockable gas springs with a valve system in the cylinder .

And the gas spring keeps the pressure thrust.

what do you need?

and the system to deport the control block each side of the table. it's possible to meet the control system in one for two cylinders to avoid the effect of balance.

this type of gas spring is Rigid locking in push-in direction, push-out management Relatively rigid

The design is simple because the system is simple. it will be very effective if the gas spring is dimensioned and appropriate.

The failure of the system is that it is necessary to adjust the pressure of the gas spring more or less related to the weight of the options (drawers, tool support, etc.) chosen by the user for the table. The height should be adjusted without aditional weight on the table otherwise it will be hard.
The user should adjust the height before putting heavy objects on the table, like the current design.
