Hi guys.
I searched the forum for a similar topic but couldn't find one.
Anyway, I'm thinking about making test track by myself. Have you ever done one? Any clues or ideas?

Do you mean; Rollenprüfstand ? (like this: Marklin rollenprufstand )
I built one myself, simple wooden construction and some ball bearings. So far it is working fine, although the ball bearing position can not be adjusted. Photo below:

Same idea, small ball bearings but this time mounted on L-shaped aluminium profiles, allowing any piece of track to be a test track.

Thanks for a picture. I can find them as well. I'm actually looking for someone who has made it and can give details of what to use and how to do it.

I have just found this:

That's another very nice build. Here are the parts that I have used. Original drawing is here.

This is great.
How far did you put bearings from eachother?

16.5mm = the distance between the regular tracks in HO scale.

I meant the distance between axis?

Right, sorry :) As close as possible without actually touching. So probably something like 6+1mm. Will double check when I get home.

No worries.
But did you put anything in this ares to stop ball bearing from scratching the alu piece?

I though of the same but there was no need for it. A burr on the alu inner side is enough spacer. So for once don't clean up that hole after making/threading it :) If not enough then give it a tap from outside, the alu will easily bend and make a micro "cone" on the other side.

I've also applied a touch of CA glue between the bearings and the axle/screw, as the shrink tube was not a very precise spacer.

Ball bearings ordered. All the other parts are easy to find and probably in a garage somewhere Wink
Half term is coming and this time it's my time to stay with kids so hopefully should have it ready for bank holiday BigGrin

Did you measure this distance?

Yep, it's as mentioned before, 1mm between bearings, so the side holes/axle centers are 7mm apart.

Enjoy your/their vacation time ;)

Hi Guys
I just wished I had the skill to make one, unfortunately, I don't have the knowledge of where to get the parts, the tools to make it and finally the patience to do.

My fingers are like sausages doing this type of thing! How about offering to make them for members and charge them for your time and parts!

As my daughter would say 'winner, winner, chicken dinner' please don't ask me what it means, I don't talk 18 year old girl!

Regards
Harry

Hi Harryv40.
This looks like an easy project but it is probably gonna take few evenings and a few f... words. And at the end it won't look any as good as product you can buy at shop. And if I charge you for this you will be f.... wording me. Therefoe let me recomend you this one.

I'm thinking about buying it for myself.

You mean that it is possible to get through a MRR session without any F words? Now I have something to aspire to. BigGrin
Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

What is MRR session?

If MRR means anything to do with loco fixing and amending then no, no way. I'm swearing on myself "why did I do this or that?" and "this is the last time I'm doing this"
