I have only just found this forum and I hope to take part in the future. I have been making, on and off, Simplex for about 18 years now! due to work and moving house a number of times during that time I've never really got going. But since early retirement and the chance to build a proper indoor workshop, by commandeering part of the garage, I've made good progress. Anyway I didn't come here to bore you with that! What I'm looking for is plans of or advice or pictures of a stand to hold the loco to make construction easier. Now that the chassis is too heavy and awkward to lift and roll on the bench. I want something to hold it up off the bench. I saw one at the last ME exhibition that holds the buffer beams and the loco can revolve and be locked in postion by a sort of indexing plate and plunger to get at the underside it also had screws at each end to raise or lower each end. Unfortunately in my excitement! I didn't think to take pictures  . I really would appreciate any help that you might be able to give me. regards Deric |

Made mine from Dexion and a 40:1 right angled gearbox at one end and a plummer block on the other. The stand can be lengthened as you want and the loco rotated to any angle. No adjustment in height though.

I am trying to builds such a stand at the moment. I am going to fit an indexing disk but how many positions are really required? 4 gives you the basic positions. 8 give you positions every 45 degrees. Are more needed? One of the MEs has an article that says the author used 16 index positions but suggested 12 would be enough. Has anyone experience to back 8?

I've got eight on my stand for Rob Roy and it has seemed adequate, for the sake of a few holes I would put a dozen in on the basis that it is easier now than later. When you mount the boiler it doesn't half turn round quick  Andy |

Hi Deric If you go to my website www.dr-john.org and go to page 8 in the Simplex section - the last picture on that page shows you the cheap and cheerful stand I made. The major problem with many of the "commercial" type stands is getting the loco on and off. I have a video somewhere of how simple it is to get the loco on and off my stand single handed - if you are interested, I will find it and post it somewhere for you to see. DJ P.S. Thanks Roger for the plug!  P.P.S. Found what I was looking for - I was sure I'd put this up before, but can't find any trace of it - Alzheimer's a wonderful condition - you can hear the same joke 10 times a day and still find it funny!! ;D ;D www.dr-john.org/spit |

The 40:1 gearbox I had around me and was free so I have the option of variable position.
To be honest I can't say that I have used it often in more than 4 basic positions. Vertical, inverted and about 45 degrees either side of vertical.

As long as you are aware of what you're up to and keep a hand on the heavy bit until you tighten the bolts, no problems so far. I've locked it in position in every possible angle with the boiler and cab in place. DJ |

Hi, All, I have finished making my engine stand! Why haven't I made one of these before?? it makes work on the chassis so easy! I have taken some ideas and adapted and put some dimensions to them The index hub has 12 holes and is plenty. I have spring loaded the indexing plunger and with plenty of 'play' the plunger snaps down into the hub as soon as it lines up. So I lift the plunger then move the chassis slightly and release the plunger and it drops down into the next hole as soon they line up, it seems pretty safe to me. When the model gets a bit bigger and the centre of gravity moves higher I will invert the angle bracket attaching the buffer beam clamp this will effectively lower the CoG with regard to the hub. Although the stand was stable when sitting on my work bench I decided to fix it/them down to a base board on my assembly bench and it is now very stable in all positions In all the the materials were from the scrap bin apart from the mini bearings I paid £5.95 for ten from Ebay. Here is link to a photo album with some pictures I've taken (a bit 'grainy' I'm afraid) cid-5dd8f42788029092.skydrive.live.com/redir.aspx?page=play&resid=5DD8F42788029092!116 Any questions? I will be more than happy to help with dimensions etc. Best regards Deric |

Thanks for the pics, Deric. Its great to see other people's work. A few questions: Nothing but the spokes seems to be painted but no rust; how do you manage that? Why the elongated holes in the frames for the steam inlet and exhaust pipes?
The brakes look good. I'm thinking of fitting them to the rearmost two wheels only, because of reputed clearance issues with the front hangers. Have you worked out the clearances?
The stand looks good too. Thanks again for the report.

Hi Deric,
I'm reaching the stage with my Simplex where I'll need a stand and yours seems to be a good version that I'd like to copy.
A couple of questions please:-
1) do you lock the vertical travel mechanism or does it rely on the "lead screw" to stay in the set position?
2) How ever do you keep your workshop so clean and tidy!! Do you have a secret assistant to tidy up ? (Only joking but it looks great).
regards
Nigel

gdd &nigelh - I've PM'd you both. As well as drawings for the stand I'm working on a CAD drawing of the front brake hangers and cylinders.

Deric,
Would it be possible to copy the relevant content of the PMs here as well so more of us can learn how you solved these problems?
Many thanks,
Jem

Deric,
Nice looking stand. Would it be possible to make the drawings available?
Russell.

The brakes look good. I'm thinking of fitting them to the rearmost two wheels only, because of reputed clearance issues with the front hangers. Have you worked out the clearances? I'm fitting them to the rear wheels only. Brakes on an engine are useless when you are running anyway. They are a parking brake only. I considered fitting them to the front wheels (behind the wheels) but decided that the complication of reversing the motion was not worth it. Russell. |

Hi, all,
Firstly, I am flattered that people are interested enough to respond to my posts! I've never contributed to any forum before.
Jem I'm sure you wouldn't be interested in the content of the PM's they were 'chatty' ones and didn't have content regarding my loco or stand as such.
With regard to the stand and the brakes, I am about to 'launch' my website onto the world this weekend. It's taken me ages to do (I'm not very 'e Savvy') and drawings will be available there.
I will post a link to the site over the weekend so don't go away !

G'day Deric,
Thanks for posting your photos. Lots of good ideas there for when the time comes to make a stand.
Looking forward to checking out your website!

Hello to you all! I have made an attempt at website I'm afraid it's not as 'flash' as some of you guys can do - but I'm working on it! It's so time consuming tho' isn't it? In the drawings are those for the Loco Stand and I have added some for those who have asked about the Simplex brakes and a possible solution to the tight fit of the front ones. dericswebsite.weebly.com/index.htmlI believe the front brakes will work as I have shown them modified and whilst I also think that they might 'rub' on the top edge of the blocks against the wheel at full suspension downward deflection I am confident that this will not cause any braking effect and could be relieved by slightly easing the tight spots. i also believe that the clearances around the front hangers will allow them to be easily dismantled if required. The draincock linkages are the next thing to look at and by drawing them in 3D see how they sit amongst the valve and brake gear. I suppose I should point out that I am providing these drawings in good faith and that you should check them out for yourself. That over - I hope they are of use to you. It would be nice to get some feedback from you on the site and if the content was of use, so please let me know. Best regards Deric |
