I do use this but I have never really been happy with it. The rollers are set at 32mm apart to suit Peco track but as with the inherent slop in Peco track I find that the loco being tested tends to hunt from side to side never really giving a true reflection of how it&#8217;s actually running. I tried once a few years ago to reduce the distance by adding washers behind the roller bearings but my washers were too wide and all it did was seize up the rollers so I took them back out. When I bought my mill I had the bright idea to mill of 0.5mm from each spacer to reduce the slop but never got around to it until yesterday. I was about to dismantle the roller sets to mill them when I remembered that a former guild member had given me a collection of various nuts, screws and washers so I had a look through them and found some 0.5mm thick washers that were also very thin in terms of the washer area which while acting as a spacer to take off 0.5mm didn&#8217;t inhibit the movement of the bearings.<\/p>\n\n\n\n<p>Hopefully this photo&nbsp;will show what I am struggling to describe.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/Washer.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"130\" height=\"147\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/Washer.jpg\" alt=\"\" class=\"wp-image-5717\"\/><\/a><\/figure>\n\n\n\n<p>This cured the hunting immediately, so I can&#8217;t recommend it enough to anyone else experiencing the same issue.<\/p>\n\n\n\n<p>If you are connecting&nbsp;power directly the the motor the HH rolling road units are fine but if you actually want to test pickups then that&#8217;s a bit more interesting because the unit really isn&#8217;t designed for it. For years I have used a bit of a lash up of some lengths of copper wire and some crocodile clips to transfer power to each of the wheel cradles.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"474\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-1024x474.jpg\" alt=\"\" class=\"wp-image-5718\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-1024x474.jpg 1024w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-300x139.jpg 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-768x356.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-1536x711.jpg 1536w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-2048x949.jpg 2048w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99999-500x232.jpg 500w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption>Hobby Holidays Rolling Road Refinements<\/figcaption><\/figure>\n\n\n\n<p>After doing a recent&nbsp;repair job for a fellow member which required testing pickups I thought it about time I did something a bit better. I found in my stash of &#8220;it will come in useful some day&#8221; materials a strip of aluminium which when cut into two pieces was perfect to create two bus bars. I milled some slots in them to allow adjustment to&nbsp;cover all my rolling road cradles (mine is a 5 axle jig).<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-scaled.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"208\" src=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-1024x208.jpg\" alt=\"\" class=\"wp-image-5719\" srcset=\"http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-1024x208.jpg 1024w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-300x61.jpg 300w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-768x156.jpg 768w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-1536x312.jpg 1536w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-2048x416.jpg 2048w, http:\/\/www.railway-models-and-art.co.uk\/blog\/wp-content\/uploads\/2022\/08\/99997-500x101.jpg 500w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/a><figcaption>Hobby Holidays Rolling Road Refinements<\/figcaption><\/figure>\n\n\n\n<p>As luck would have it in the front of the rolling road units is a hole to allow you to fit a hex key to get at some cap screws on the rear. These were just the right size to tap M4 while&nbsp;still allowing the hex key passage. There are also a set of holes already tapped M4 on top of the adjusters which will pass the current to the other side.<\/p>\n\n\n\n<p>This is the bus bars in place. All that&#8217;s left for me to do is shorten a few cap screws to make them fit better.
