Now that I am getting stuff sorted after the move back to Singapore, I thought I would kick start things by building a 00 Gauge rolling road based on the O Gauge design provided by the Heywood Model Railway Group : http://www.hmrg.co.uk/techtops/rolling.htm

I went to a aluminium stockist and a bearing stockist this morning to get the angle and miniature bearings. In the afternoon I bought the plywood (i bought 18mm as opposed to gluing two 9mm pieces as per the Heywood design).

Starting out after cutting to size  (timber is 65 w X 450mm l) :




Double check on Loco Size & Location




Clamped and pilot holes drilled




Holes drilled




Underside with countersunk holes for bolt heads





Temporary check to set locomotive (no bearings yet)





Epoxy Resin in place to set the bolt heads (now to leave in place to cure overnight)





Details of bearings - they are small! (the units for these will be built tommorrow)

This is a great "how to," on this subject, Darren.  I have to make one for my G scale loco I'm building.  It will be a big help.  Thank you for posting it.  :thumbs

I have certainly learned a few things in the build! - see my post below

I completed the build today by making up the bearings which comprise 5mm bolt, two washers , spacer and nut. I had to add a spacer as the nut size if next to the bearing would foul the flanges of the locomotive (lesson learned here as there were smaller internal diameters from the stockist but I chose a common internal diameter as I hadnt thought about the flange depth. Choosing a smaller internal diameter would have avoided the need for the spacer) The spacer is some styrene tube cut to size. The next problem that arose was that with the spacer, the roller units touch on each side (causing a short circuit) I have fixed short term with insulating tape in between but will need to get to reduce the length of the bolts a tad! (lesson learned no.2!)





 



I also cut the varying support pieces for wheels that dont require roller support




Final fuzzy photo is with test locomotive at full speed going nowhere , it works!

If you recall I had made a mistake in having bolts that were too long and had to put insulating tape in between to avoid a short. I sorted it for free when I had a rummage in my bolts box and found the adjustable feet from a couple of Ikea Laundry Drawer Units that were surplus as the units were installed inside cupboards and the feet meant they were too high to fit. These bolts are a good fit and sides are now electrically isolated.




In addition I modified the angle sections with the addition of spacers using styrene (superglued) so that I dont need to fiddle with them when setting up, they automatically are at the right offset (see below)

Even though we have a link to a similar build in our Index I think your explanation and photographs are much clearer Darren so I have added this to the Index as well.

Dareen - I'm being my usual self here - confused !!!!

I can see the angles over the outside edges of the ply base.  The angle that holds the ball races is the other way up (i'e' it sticks up not down :roll:) forming a square "Z" shape.    Is this piece of angle trapped under the main piece or fastened to it in some other way ?  I can't make it out from the photos.

Also, you didn't say what size the bearings are - I presume that's fairly critical.  Is it just by trial and error or is there a definite size ?

p.s. I like your bright shiney Workmate. :thumbs

Thanks Owen.  I presume the bearings would be the same diameter regardless of scale - only their position would change.........:roll::roll:

If i was going to make a further refinement it would be to change the nuts on the top to wing nuts....(I have a mini wrench and socket to hand on my workbench in the meantime...)

I actually scaled down the bearings from the standard design which was for larger scale - the industrial place I went to get them here had every possible internal and external diameter imaginable!

Re the workmate, this is my second one - they are a good design (especially as I no longer have shed, garage or garden as I am living 20 floors up in an apartment), my last one when the jaws wore out, I made new wooden jaws for it that were better than the originals!
