great stuff Brian, my model when it arrives (have ordered 2) should be easy! Thanks so much for your post in another place which brings me back to Glen Ogle

Well, while I was away having a quick snooze, (my recent stroke tires me out so quickly), I see some of you have posted replies  ;D, so I will have to continue.

I have started to assemble the cleaned up but as yet unpainted model parts, the single cylinder and its feed pipes have been mounted onto the sled like structure in this very unkind view.    The half mm hole I have drilled for the replacement crank shaft can be seen at the bottom of the rather misshapen casting of the connecting rod on the cylinder casting. [8]



The track rails  [1] for the traveling log carrier [13], have been attached to the flat belt tensioner [6] which has had the heavy tensioning roller cut out, and a hole drilled through it, and the two side piece supports, ready to work with motorised flat belt when fitted.



And the log manipulating levers [14]  [15] and [16] have been attached to the traveling log carrier.





the saw wheel bed [2]  has the cast shaft and multiple speed adjusting rollers cut off, the stepped rollers had the remains of the cast shaft filed away, and a hole drilled through its centre.   The shaft bearing blocks have been drilled out as near to the actual bearing block as I could manage, and a new shaft inserted through the drive roller, stepped pulley and the two bearing holes, and then the and saw blade glued to the end of the shaft.

Pictures to follow.

That'll do for now, I'm tiring again, sorry.

That's looking good, Brian!

don't rush it Brian we can wait and its very interesting

I don't seem to have a rush in me at the moment Peter, thank you for your patience.

To continue with the sawmill build.  The circular saw wheel supplied  [4] Is a white metal casting and does not look very convincing, so I thought I would substitute it with one of the Dremel slitting wheel blades, this is slightly larger in diameter, but with a little filing to the casting position in the saw table, can be accommodated.



The difficult bit is fixing it to the substitute axle, which is quite a bit thinner, but by sliding a piece of the smallest heat shrink sleaving onto the shaft, and heating to shrink, it seems to have worked, although it does not run true.

The castings have acquired a coat of acrylic paint over a Halfords rattle can grey primer, and the various sub structures have been glued into place on the rail bed.



You can see the new shafting to the saw wheel and the heavy steam engine fly wheel that I have fitted, but as yet, I have not attached anything to the free ends of the two shafts.



Anther rather blurred view of the components.



And an overhead view.



And an end on view.  The steam engine heavy flywheel at it's base is supposed to connect, via a flat belt, through the belt tensioning structure, and on to the saw wheel shaft.



And the cause of all this flurry of activity, is this additional board that I have made to allow me to take a small working section of Glen Ogle to the South Yorkshire group meeting at some time.  You can now see why the track layout is necessarily unusual as it joins up to Lochearhead.



Here shown attached to the 2 ft Lochearnhead board from the bottom of the Glen Ogle pass.



A back scene and side boards fitted temporarily in place while, I decide how I am going to lay out the saw mill building and sawmill, and where about's the rail way line is going to terminate in the scene from the off scene junction point.



I think that's about it for today while I play with the electric motor or motors.

Here is an update on the current state of the model, I have now started to build a covered work area which may be covered with wrinkly tin if I can find some that looks real enough.



Here is log mounted onto the revised log carrier and showing the first pass cut at the end of it's travel.



Still lots more to do.

that is looking really excellent Brian and pleased to note the log on the carriage is the sort of diameter I hoped for (about 3 scale feet in my HO scale). Like that first cut

[gtmspyder]

It's been a bit quiet on here I know, but that's because I've had to go back into hospital again for three days, having had another small stroke, but I'm back here now, whoopee.

Right then, I've been having a think, which you have plenty of time to do while whiling your time away in a hospital bed.
I'm thinking of converting the single cylinder steam engine into a small generator, which means it can go anywhere on the site, with a saw drive motor connected to the saw shaft and in view, rather than having to be hidden from sight with the drive belt option.
Any thoughts anyone?

Regards,

BrianT

Sorry to hear about your 'time out' Brian, and pleased to see you back in action. The sawmill is looking really delightful!

David.

[gtmspyder]

Thank you for your well wishes David, it's a bit of a nuisance.

As well as pondering over the sawmill drive arrangements, I had another think about how the sawmill would receive it's incoming logs to be processed. I had laid a point in off scene, ready to carry goods to the site, but at time, had not thought what those goods would be.

I was originally going to build the sawmill diorama into the little layout base board, but thinking about the layout of a saw mill, having looked at the pictures kindly researched for me, I realised that goods in and goods out, really aught to be via two separate spurs off the main line, the incoming, which I had made provision for, would ideally have a gentle rise to get the wagons above the saw sled, to allow logs to be rolled off the wagons, and down to the saw sled.

You can see the proposed saw mill position where I have marked the hole positions for the roof supports.

This first picture shows the incoming spur, with it's fierce "S" bend to get it into position, this section of the line will have a built in rise.

[/URL


To alleviate the strain on the rail joint caused by this very tight bend just after the point, I have fixed 4 brass screws just below the rail level, and with the rail laid straight across them, solder the rail to the screw heads, then bent the rail into it's "S" configuration, and held it temporarily with drawing pins.

[URL=http://s1010.photobucket.com/user/gtmspyder/media/DSCF1915_zpsjl8dpsxa.jpg.html]



I made no provision for the outgoing spur to the main line, and because the main line rail is all ready on a 9 inch radius, any point would have to be hand built in situ, so this is the next stage



Again to alleviate any strain on the Peco rail fixings while I worked on the point assembly, I put a screw either side of the running rail, and soldered the rail to them before bending the spur rail into it's new position.

I now need to remove the remainder of the Peco sleeper moulding, and replace it with copper clad sleeper section, where the point is to be built up.

I have mislaid my copper clad 00 gauge sleeper strip, so that's brought that little exercise to a standstill until I can get someone to run me to my local model shop, Marcways of Sheffield.

I shall just have to get on with slitting the base board each side of the incoming spur, and wedging it up a little, and drilling for the log roof supports.

BrianT

A little more done today ::),It's most frustrating when your limbs do not respond to the commands from the Brain :(
An over all view of the little baseboard.



A closer view of the rural sawmill with it's new wriggly tin roof.



An internal view of the sawmill.



With the roof off, reveals the same overall layout that was on the small diorama board as before.



The log delivery spur has been raised above the saw bed, and rails run from the track to adjacent to the saw bed at the log delivery end.



You will note that the saw drive and the single cylinder steam engine still have no electric drive motors,  so we could be onto plan "C", has anyone got a plan "C" tucked away in their "to do" drawer :-\.
The problem is that to attach a motor (generator) to the steam engine, the motor would have to be quite small to look realistic, and all the motors seem to be overlarge for the situation, or if small, revolve at absurd speeds, and gearing down is not really an option.  The saw blade drive motor could take a larger motor, but again, the speed would be excessive, and if the motor was bigger than the generator supplying it, again, it would look absurd.  So at the moment, having movement at these two points is on hold, while I have a think.



The manky colours are only to relieve the bare base board colour, and will eventually look nothing like what you see now.

That's about it for now.

Regards,

BrianT.

I have ordered a couple of Roco bolster truck wagons to replace the Roco standard wagon I have parked near the log deliver rails, these two will be duly laden with logs for delivery to the sawmill.

Tomorrow, my son is having the day off work to take me back to the hospital for some more tests, so we should be able to divert to Marcways on Attercliffe for some 00 sleeper strip, so I can then get on with the point construction, that's going to be fun in my present state ;D

Hi Brian,

what is the diameter of the motor you would look for? and what would be the approximate length? I have a number of cheap mini servos with gear defect - not repairable as there are no spares available. Probably a motor from there could fit your sawmill.

Let me know the size and I have a look.
Regards  Gerhard

[Gerhard Novak]

To give you an idea of the size of motors I am speaking I made a short video. Just with the phone so I apologize for the quality.
What you see here is a helicopter in H0 scale, made by Roco. This is a static display model, but I wanted some action. So I put in a motor and a battery - and the people have something to look at during a show  ;) Especially as you can move the thing around and it still runs...

What I also modified is the landing gear - the original plastic thing was too fragile so I made one from brass wires.
