Do stringing machines need replacement parts often?
I'm planning on buying a used Laserfibre quantam TT and I'm concerned about later on in the future having to replace parts that may break down.
I've never owned a stringing machine before and don't know which parts or how often stringing machine parts need replacing.
I figured out that the company that made this machine went under so I'm worried if I ever need to buy replacement parts for the machine.
For stringing machines is it easy to replace parts with other brands/models (since I don't think its possible to get parts from a company that went under)?
Which parts and how often, if ever, break down and need replacing?
For most modern mechanical machines, there are rarely any parts that fail - sometimes springs in crank machines, but usually you can always get a replacement spring. Dropweight machines usually have a spring inside the gripper that is used as a one way rotation - these do fail at times and require replacement. Others have a ratchet system, the teeth in the ratchet can occasionally have problems, but usually a good repair shop can make something similar to suit.
I have an old StringsAll machine that use a rubber ring for the gripper, i.e. the rubber sits on a rotating disk/cylinder, and you wrap the string around it, then put a loop under, and the friction of the string allows the rubber to grip under tension and away you go. However my rubber rings have perished and are no longer available - everything else seems fine.
For electronic machines, motors can fail but usually it is the electronics that fail, and some parts are available, some aren't - you pick.

Haha thanks for the reply learned quite a bit from it. This was a pretty old thread, about half a year ago. Already got my machine now and its working great and I doubt I'll need replacement parts for a long time.
Though thanks for the thorough answer, I'm sure it will help someone who ends up purchasing the machine in the future.
Yes, I haven't been on here for a while. Another thing - though, not necessarily replacing parts, but maintenance. The fixed clamps and string gripper - if they are diamond coated, do need to be cleaned from time to time. Use alcohol with a small stiff bristle brush - methylated spirits is also ok, but leaves a little residue. I found that after stringing a fair few racquets, that the gripper or clamps start to slip a little, especially at the higher tension, and often due to tennis racquets. Cleaning them will make them good as new, and require less clamping pressure - equating to less crunching of the string. If you use a linear gripper, you won't have this problem - but the gripper ball bearings may go a bit dry, so do need a bit of oil or grease from time to time. But be careful if disassembling the linear gripper - and count the ball bearings and where they go - either that or replacing linear grippers are usually available for most brand name machines.
