Just an idea, could you get the piston made in hard plastic ?xvivalve wrote: ↑Thu May 25, 2023 3:04 pm Rimmers stock servos that can be made to fit a Sprint, they are not original Sprint servos. I don’t know first hand what needs to be done to adapt them but Ken Clarke does. There was also a thread on here about them.
Club stock rarely exceeds one unit and yes they are exchange with a £100 surcharge if your’s isn’t serviceable. The reconditioner currently has one unit I took in exchange and I’m waiting to hear if it is viable or not… With the exchange surcharge they were £270, but I’m anticipating a slight price rise.
We are still waiting on a prototype with an aluminium piston instead of Bakelite but it may prove too heavy for the vacuum available…
The cheaper option is to use an 1850 servo.
No, it's been tried; can't get them smooth enough to hold the vacuumwhydidistartthis wrote: ↑Tue May 30, 2023 3:28 pm Not actually seen one of these, but could it be possible to 3d print them?
It would require tools to be made, which would be prohibitively expensive.new to this wrote: ↑Thu May 25, 2023 10:04 pmJust an idea, could you get the piston made in hard plastic ?xvivalve wrote: ↑Thu May 25, 2023 3:04 pm Rimmers stock servos that can be made to fit a Sprint, they are not original Sprint servos.

Dose the Bakelite piston always brake in the same place ? have you got a picture of the Bakelight piston ?xvivalve wrote: ↑Thu May 25, 2023 3:04 pm Rimmers stock servos that can be made to fit a Sprint, they are not original Sprint servos.

They are similar, but unfortunately a different diameter. Both the 13/1500 and 1850 servos share a piston with other makes and models but the Sprint is almost unique to the model; it's only the fact that some early Fords use the same piston that makes the research into alternative fabrication even halfway viable!Richard the old one wrote: ↑Thu Jun 01, 2023 5:56 pm Would the piston be the same as the piston inside a 1500 servo as if so we could consider cannibalizing a 1500 servo as I believe they are more common?
