Servo Posts

[Chris Cairns]

This follows on from a recent topic relating how easy it is to fit Radio Control to an Accucraft locomotive.

I have a 2nd hand Edrig where a standard size servo has just been mounted using long bolts into the pre-drilled holes in the running plate. I actually added rubber mounts to the servo to cut down any vibration feedback.

I have a new Accucraft Ragleth on its way and I would like to mount a standard size metal geared servo for the reverser control. However I'm having difficulty locating a supplier of the right sized servo posts (we no longer have an R/C outlet in the city centre).

Can anyone recommend a source for suitably sized servo posts please?

Thank You.

try these guys http://www.sloughrc.com/there very helpful and have lots of stock worth a phone call

http://alshobbies.com/index.html or try these http://www.cornwallmodelboats.co.uk/index.html they both stock a good supply of r/c fittings and are pretty quick on delivery. As you will see Cornwall model boats do a cracking range of modelling items.

When I did my Lawley about 18 months ago I bought several lengths of M8 (?I think?) threaded bar off ebay, along with washers and nuts. Bit bodge it and scarper but it seems to be okay. I would post a link but I can't seem to find the ebay link to the supplier.

Sorry I can't be of more help!

plenty listed on the bay under "M8 Studding" Yes! I got caught with that one too. Modern term is threaded bar it seems. When young we were taught to actually make our own studs in the toolroom, or "turn up some studding" Ebay is still using the old expression,

B&Q do sell some small studding. May not be as small as M8 but might be worth a try.

Thank You for all the suggestions.

Not found anything in those radio control websites (these posts tend to be generally used in R/C cars) and I'd prefer not to use studding as that may not stop any vibration getting to the servo.

Currently looking to see if I can get the right sized PCB standoffs, or alternatively I could use Mamod/MSS chassis spacers probably with a washer or two added for the correct height.

why not make your own out of some 1/4x1/4 square bar? should be easy enough to do

I'm very envious of those on here (and elsewhere on-line) who have access to the right workshop equipment, tools, materials & skills to quickly run off something like this. Unfortunately I'm not one of them so have to rely on the ready made option for now.

Have a talk with Roundhouse, they make standoffs with M3 screws to support the reverser servo in their r/c locos. They usually sell parts separately if you ask nicely. They call them servo mounting posts.

Electronics parts shops sell similar standoffs for mounting circuit boards in boxes and may have something suitable.
