Gerald, Is Gaslifts available in U.S.A if so can you get us details of the stockist. You could also give the details of the manufacturer and model of the existing gaslift. You have also said that the gaslift is going to be replaced by a coilspring in time to come.
I am trying to get all required components shipped from U.S.A by end of next week. I hope that by then details of the spring would be available. Hope we are not pushing you too much.
If everything goes well I am planning to have my machine going before the year ends. |

For "Gaslifts" in USA you can look at part 9416K18 from http://www.mcmaster.com/, but you have to specify a force. The gauge plate weighs 2.4kg, the 50x25x3 tube weighs 1.5kg, the bit of rack weighs 0.4kg...that is about 4.5kg [10 lbs] total. My spindle weighs 5kg [11 lbs) that is 9.5kg [21 lbs] altogether so I would have to specify a 20lb gas-lift from McMaster. You are going to use a router, so you have to go for the 15lb option - there is no other choice.
Regarding the coil spring, that should be fairly easy to work out by the weekend. |

I will wait for your coil spring option as well before making a decision. |

The best spring that I can select from McMaster, for balancing a 6 lb router with a 10 lb slide, is part no. 9664K27. That is actually a parcel of 5 springs each 36" long! You need to cut a single spring only 7.3" long from all of that. A single pre-cut spring is not much cheaper, and then you can't play with the final balance - get the long stuff and then you can experiment. |
