Monitor Rotation using Timing Belt

[kahlid74]

I not super knowledgeable about timing belts so I was hoping to get some help finding two timing belt pulleys I can use.  I need an 8MM (5/16 in) bore Timing belt pulley for my stepper motor and a 3/4 in. Timing belt pulley for my shaft.  I've found some with both 5/16 and 3/4 on McMaster-Carr but they seem to be for different size timing belts with different pitch.

Anyone know where I can find some these with the same pitch and sized timing belt?

mcmaster and grainger sometimes list the supplier of the items they sell.  look at the manufacturer and track them down directly.  they will know what sizes are available, etc.  I did this with pogo pins a while back, had to go right to the maker but they had what i needed.

it could well be easier to find a belt you can live with and then find sheaves (pullies) to match, more variety of those around.

Following your advice I pushed to manufactuer's and found these guys have 5/16 and 3/4 in bore L series pulleys with 3/8" pitch.  So it should be good to go ordering these.

This is exciting.  I've been on stand still looking for pulleys.  My arduino code is almost ready too!  Soon, there shall be a rotating 42" TV in the near future.

glad to be of service.

Just another update in-case anyone else ever needs them, I called them and got directed to Quality Transmission Components and they have boat loads available.  So yeah, awesome sauce - http://www.econobelt.com/e-store/Pulleys.htm

So once pulleys arrive try out Arduino code and then I'll start a project thread about building the cab lol.  It's going to be a monstrosity.

Cant wait to see this rotating monitor project finished! Dont forget to post a link to your project over at Automated projects forum.

My biggest challange is time.  With Mechwarrior Online coming out Q3/4 of this year I need to finish my Battletech pod, which means this machine is most like going to be built skeleton wise and then site for several months until BTech pod is done.  I do however plan to use stepper motors in the BTech pod to when you close the pod door move a rail system with three monitors towards the pilot and bloom like a floor inside the cab.  I'm super excited to get to that one!
