Post My DIY Edelkrone Sliderplus style slider on V-Slot Rails
Finished this project about 4 weeks ago and quite pleased with the results from it as both a time lapse and video slider. I've used a couple of 20x40 Openbuilds V-slot rails which slide through rollers on the slider mounting carriage. A recirculating Synchroflex belt moves the rails and camera carriage at the same time. My design doesn't give a massive saving in overall length at 665mm long with 768mm of actual travel, but if it were constructed conventionally you'd need to add the redundant length of the camera carriage (120mm) and end brackets (95mm) so a more realistic comparison is 665mm vs 983mm to achieve 768mm of travel.

My DIY slider also uses a further length of 20x20 v-slot and mini v-wheels to provide camera axis rotation which I've found to be pretty effective.

I'm using fast and slow motors from Digislider controlled by a Digislider Speed Controller and Dynamic Perception MX3 respectively. Performance as a video slider is much better than expected. Only a bench drill and chop saw along with basic hand tools were needed to build this. The finish is a bit rough, but it's the results that count!

These are my first time lapses and also shot from this DIY slider:



Critique welcome.

Very nice some clever ideas . Dont understand way people are still messing about with other stuff for rails . V slot is cheap and it works very well . Only problem i have had with it is supply ! Have you had any problems ? . Suppose its early days for them just hope they build up more stock .

I'm in the UK and ordered from http://openbuildspartstore.com/ first time. Delivery took an age and had incorrect and missing parts.

I now find https://www.robocutters.co.uk/ to be a reliable supplier.

I agree that V-slot is an absolute gift for motion rig builders. It's just so versatile. My only concern is the durability of the Delrin V-wheels. I noticed a couple of days ago that the OpenBuilds store has added what they call a 'Solid V Extreme Wheel' made from polycarboante. Might give those a try if the existing ones start to wear.

That is a neat peice of engineering, video looks smooth, yet to order some rail to experiment with. There is a metal wheel kit available as well as the various "plastic" wheels, not sure how well the the ali rails would wear though? I see you are using a "proper" battery to drive the unit, I find my Tracer seems to go on forever even with five steppers :D

Hi, D1, how is the robo arm progressing.

It would be nice if the extrusion came in longer lengths. I think they sell one meter and one and a half meter. I like 80/20 extrusion because I can get it in 12 foot and 20 foot lengths. Would be nice if there were better wheels and those eccentric spacers for 80/20 or longer extrusions of this.

Hello www.robocutters.co.uk does longer lengths of V slot and i have also found the wheels will run on normal 20/40 so cant see 80/20 would be a problem .
Dont think there is a problem with any of the wheels for timelapse . A lot of people use this stuff for CNC machines and 3D Printers . Which as a lot more loading and speed issue so if its copping with that i think you will be fine using it for a DSLR rig . I have some steel wheels but not used them yet if any thing its the bearings that are the weak point especially the mini ones . But their again that doesn't concern me greatly .
I Mike afraid no progress on the arm been busy at work and its camping season for me . Not managed to get to Scotland but been pottering round North Yorkshire and Wales so that's fine

@Mike - Looks like you're building some seriously long sliders there! I'm more interested in portability so I'm currently working on a revised design that will use 20x20.

It looks like there may be an issue with the durability of the Delrin wheels, because Openbuilds have introduced a Solid V Extreme wheel in hard polycarbonate.

@Displacement - My current DIY slider is probably quite demanding on the wheels, bearings and those little 5mm setscrews because at the 2 extremes it could result in something like a 5x increase in the load because it is cantilevered, but any flexing seems to come from the tripod/head, which you have to expect when supporting it this way.

Very cool little rig Andy! Footage looks great. Love the engineering to get the slight pan motion. Do you have any BTS footage of the build? If so post it up at Vimeo so I can add it to my motion control channel.
Cheers,
Doug.

Sorry Doug, no BTS. Busy trying to finish the drawings for a lighter and slimmer version.
