Some years ago, I looked into the workings of the Pentroller which was designed by Stuart Hines for use with Portescap Coreless motors. I include a link to this blog in the hope that some may find it useful. Pentroller Blog. Regards Pete

I'm looking forward to following this. it will be interesting to see how you can work in such a small scale. Regards Pete

I'm very envious, you have some interesting gatchets.

Hi All, I've been working on a steam assisted uncoupler for ' De Snitzlton ' which is basically a simple motor and gearbox that will hopefully animate the uncoupler along with its operator. The progress has been more like slowgress, so I felt the need to insert a few images to log my present position. Most of the gears for this project have been taken from an N20 motor / gearbox assembly, a product that is plentiful on xbay. All of the gears required minor modification's and some gears, I've either had to make or have still to make. I must warn anyone thinking of attempting a project with these gears, the teeth are 0.15 module, total height of these teeth is 13 thou, which is only a fraction over 0.3mm. I've spent quite some time on my knee's, searching for dropped components. Here's the rear end of the gearbox, part of which will be covered by the coal bunker. Height of the brass gearbox will be trimmed down further when certain criteria has been established. Front end of the gearbox. Rotating Buffer's ? - All part Fun Town. Stay Safe Everyone : Snitzl

Just had to watch it again, great stuff.

Hi Corbs, Really nice, I just love that smoke.

I have to agree with kitpw, I've not seen this standard of modelling in a long time and there's so much of it. Some really nice details, the broken roof tiles, clothes pegs. Brilliant stuff.

Blimey, you have been busy, looks very nice.

That shadowgraph must be quite rare, lets face it, who else would want one, only used it a handful of times.

Hi, For no other reason than I prefer to use a dental bur on that particular lathe when drilling small diameter stock, it leaves a small concave without to much preasure. I still use centre drill's, but when drilling 2.0mm dia brass they tend to get in the way, I can't see what's going on.

I needed a Tenshodo type 14:1 worm and wheel for the current project I'm working on. The Tenshodo's were about the right size and would probably do the job, but a preference for metal gears prompted this sub project. The one thing that this blog demonstrates besides novice gear making, is how much time can be spent making side tracked components before work can begin on the job in hand. Now that the gears are complete, changes have been made in the main project that may render these gears as unrequired, we will see. Regards Snitzl

I'm 99% sure they are Fulgerex, Lemaco are very similar but not quite the same.

Hi all, It became apparent when building the footplate for 'De Snitzlton', that the Mashima motor was not only to large in diameter, but also to long. I checked out the 'Motors and Drive Systems' thread, here on RMweb and was a little shocked to discover that all of the bespoke model railway motor manufactures I was familiar with, have gone, including Mashima. One thread, in particular mentioned the used of an 'N20 motor', so I've placed my order and await delivery from china, a second potential candidate is 'N-Drive 1015', which I'm also waiting for. Both these motor's have the same dimensions, so there's a chance that they are the same motor, we will have to wait and see. Chassis has been modified to take one of these smaller motor's, the footplate and chassis now have a small location ring which will also align the motor and locate the boiler. Dental burs are used to add texture to the boiler and chimney extension tube, this loco needs to look heavily distressed and ready for the breakers yard when complete. Could do with a clean up, brass filings all over the place. Next, I'll leave the body for a while, and take a look at the coupling mechanism. Thats all for now, Thanks for looking.

Hi Mike, In the past, I've made three models with this type of footplate and managed to make a reasonable job by cutting a piece of brass for the valances with only the top edge shaped to the footplate. There has to be plenty of material on these valance plates to keep everything flat and rigid and they should have squared ends and lay flat on your work bench. It's only when the loco is nearly complete that the valances are trimmed back and filed to the correct profile. Your combination of metal and plastic looks fine though, should make a nice model.

Interesting Thread, Thought I'd add a few images to it, all scratchbuilt of course. Snitzl town Harbour. The Cab Shelter Scene - Snitzl Town. Trestle Bridge - Snitzl Town. Stone Steps and Walkways - Snitzl Town. Regards Snitzl

Hi Dave John, Nice to hear a comment from a fellow modeller that thinks along the same lines. Like you, there's no doubt in my mind that Sharman compensated chassis make's a big difference in reliable running and electrical pickup, so much so that I wouldn't build any rolling stock without it. Thanks for the comment.

Hi Job, Nice to see that your still creating these wonderful dioramas in a Jack Nelson style, Its been quite a while since I've been on the forum, but it's nice to see some old faces.

Thanks jack P, It's comments like yours and from others on RMWEB that provide a little extra boost in the ongoing projects. Thankyou.

Just a quick progress report : Managed to do a little more on the chassis assembly, added the side frames and reshaped the solid brass chassis block to match the profile of the side frames, the traverse cylinder drive components have also been added. The Snitzlton : Still need to source or make some some driving wheels, the 3ft - 8 spoke wagon wheels are obviously temporary. I will make a start on the body next. Thanks for looking. Pete.

Hi Maurice, Nice to see someone trying the recycle tin can again, I actually tried using tin cans back in the early 1980's after reading an article by iain Rice, who had also used recycled tins in his own loco builds. For me, it lasted only one loco, some tins are produced from very thin material and a good supply of sticky plaster's are required with the very sharp edges produced when cutting with tin snips. On the good side though, you get some natural rusting on the area's of exposed steel. If it works for you, then that's really great. Pete

Hi Jerry1975, So glad you found Stone Steps and Walkways of interest. Pete

Hi TangoOscarMike, any complementary comments are allways welcome, as are consructive criticism and hairbrained idea's. Thankyou.

Hi all, thanks for the comments. Because this loco requires a transverse cylinder, I've decided that it's probably simpler and less troublesome to have both wheel axles driven. The chassis, machined from solid brass includes provision for a compensated flexichas design with one fixed axle and the second axle, allowed to rotate about the gearbox worm axle. A pair of Tenshodo worm and wheels are used for each of the axles and a bevel gear extracted from a scrap sigma camera lens is used for the main drive. The Mashima motor maybe a little to big, we'll have to wait and see. Worm and gear locations are determined and then soldered to 2.0mm diameter silver steel, the gearbox is machined from solid brass. Assembled axle, drops into a 2.0mm square slot. Motor is mounted vertically on two spacers and secured by two countersunk screws. Thats all for now, Thanks for looking.

Hi justin1985, I would suggest you look at all three blogs on Controller's, the first is an investgation into Stuart Hines original Pentroller, the second and third blogs take the original Pentroller design and use a few more common components to acheive the same end result. The blogs will explain all, Please use whatever you find usefull.

Hi , The PICtroller is the modern version of Pentroller, instead of analog components, the PICtroller is micro processor controlled with auto detection on the motor types, both designs were initiated by Pendon for controlling both standard motors and more importantly for Pendon , coreless motors. After reading your link 'some reports', I'm not so sure, but I believe that Pendon use the PICtroller.
