Post by: mal webber on December 10, 2015, 10:08:42 PM
Hi all ,first off thanks for the welcome ,thought  I would try and post a couple of pics on how far I have got  on the Minnie build ,this is a first model build for me so things have been going along slowly  ,but I have been really enjoying and learning with this build so far. I will carry on posting pics as I get along with the build if I can work it out.
cheers Mal

Hi Mal

Welcome to the group.  Your Minnie parts are looking good, I look forward to
seeing more of your progress.   :ThumbsUp:

I'm about 2/3rds done a 1" one.

Cheers, Joe

Hi all, had a couple of hours in the shed over the weekend and managed to get the gear selector lever done ,not a lot I know but quite happy the way it came out ,sorry just a pic on the finished part and not how I made it.

cheers, MAL

Hi Mal

The building of your Minnie traction engine looks good. May I ask who's drawings/design you are using?
I know of two model makers who are building the Metric Minnie and they are using my design plans.
Also I have been contact with a Belgian model maker who built this engine many years ago.
Are you using the metric or the imperial design?

Kind regards

Julius
Title: Re: minnie traction engine in 2"
Post by: mal webber on December 15, 2015, 07:24:56 PM
Hi Julius

Thanks for the comment .The plans I am using are from the book, Scale Model Traction Engine Building, by L.C. Mason  featuring the minnie . Building in a two inch scale I am just doubling up on the measurements to a certain extent, measurements are imperial.

Cheers ,Mal

Hello all,
 Got some shed time in this weekend ,first time this year so back onto the minnie build, drilled some holes in the horn plates to take some rivets purely for cosmetic but I think it will make the Minnie look more interesting when the horn plate are attached to the boiler .

Mal.
Title: Re: minnie traction engine in 2"
Post by: Kim on January 24, 2016, 10:15:35 PM
Those rivets look great!  But wow, that's a lot of rivets to put in there just for fun!  Looks like a lot of work. But your right, it will add a lot to the look.
Kim
Title: Re: minnie traction engine in 2"
Post by: mal webber on January 24, 2016, 10:32:13 PM
Thanks Kim
The rivets are to make it look like a full size engine where the horn plates are rivet to the boiler, not on the plans but I think it will add a bit more to the engine,
Cheers Mal.

Post by: Jasonb on January 25, 2016, 07:38:57 AM
Looks good Mal, its the little touches like that which make all the difference. Will you be adding any dummy stays and throatplate detail? I'd also suggest when you come to the tender to keep the rivits at 1/16" dia but close the spacing up to keep it looking more in scale.

J
Title: Re: minnie traction engine in 2"
Post by: mal webber on January 25, 2016, 06:29:34 PM
Hi Jason , yes i may play with the idea of a dummy throat plate can only make it look better, you suggest 1/16 rivets for the tender do you think the rivets are to large on horn plates  or just down size them for the tender to put it into scale.

Cheers Mal.
Title: Re: minnie traction engine in 2"
Post by: Jasonb on January 25, 2016, 06:51:15 PM
The ones on your hornplate slook fine but on a full size engine the tenders would have been thinner metal so smaller dia rivits were used and they did not have to contain any pressure.

Its one of those things that does not double up well on a 2" minnie. My 2" fowler which is very close to the works drawings has 1/8" rivits for the horn plates, wheels and most structural parts but the tender only has 1/16" ones and the same scaled spacing as a full size engine, note once above the water line they are more spaced out.

Thanks Jason , what you say is true 1/16 rivets it is then on the tender after seeing the picture of yours.

Thanks Mal.

lovely.......on the 4inch  they are 1/8 rivets at 3/8 centres below the waterline              Terry

Post by: mal webber on February 02, 2016, 10:46:52 PM
Hi all
bit more shed time on Minnie, so thought I would have a go at the chimney until materials turn up for other parts, did think about rolling it out of sheet but the rollers I have the use of are to big so out of solid was the way for me, still lots to do, dummy rivets top of the chimney etc. wish I hade a taper attachment on the lathe think it would have made things easer .
Title: Re: minnie traction engine in 2"
Post by: scc on February 03, 2016, 07:12:11 PM
Looks an excellent job you made of that chimney. Are you having a brass or copper top?            Yes, a taper turning attachment would be nice wouldn't it. :agree:            Terry
Title: Re: minnie traction engine in 2"
Post by: mal webber on February 03, 2016, 10:09:50 PM
Hi all
after posting the pics of the chimney last night the more I looked at it and the more  :DrinkPint: it just didn't look right looked a bit thick at the bottom and shapeless, so back in the lathe with it and I think the out come looks a lot better. Terry going to try and make one out of copper sheet.

Mal.

Title: Re: minnie traction engine in 2"
Post by: Kim on February 04, 2016, 05:59:44 AM
I'm not qualified to compare it to other engines, but I am approved to say that I think it looks very nice!  Can't wait to see it finished up and in place!

Title: Re: minnie traction engine in 2"
Post by: scc on February 13, 2016, 12:57:13 PM
Mal,    I used to get irritated by lack of shed time,  the finished engine always seemed as far away as ever.  Then I changed my approach and just concentrated on the next part and enjoyed making that without looking too far ahead. After a while you find you have made progress and more importantly enjoyed every minute of it.  As much as we all love our hobby there is more to life than shed.  (with apologies to those who disagree!)

There is gardening  :noidea:, going to work  :(, going shopping  :disappointed: and for those of us without partners or still living with their parents  :facepalm:, there is the option of having lathes and milling machines in the house as well as the shed  :naughty:

Hi all, more shed time this weekend, so whilst waiting on them deep pockets for the rest of the boiler materials thought I would roll some steel for the smoke box, and machine the smoke box door ring. sorry don't really have a build plan with the Minnie just making parts on what materials I have and how I feel.

Cheers Mal
Title: Re: minnie traction engine in 2"

Looking pretty sharp there Mal!

On the smoke stack - that vertical row of rivets is just decorative, isn't it? You turned the stack from solid, right?  But you rolled the smoke box form a sheet?  What's the thickness of the material you used for it?

Kim
Title: Re: minnie traction engine in 2"
Post by: mal webber on February 15, 2016, 06:40:04 PM
Hi Kim ,yes the rivets on the chimney are just for looks.The thickness of metal I rolled the smoke box with is 3 mm or 10 gauge sheet.

Cheers Mal.

Thanks Kim and hello all, got a bit more done on the Minnie build this week, thought I would have go at making the chimney base out of the materials I have rather than buy  a casting, this part was made in two parts and welded together as you can see in photo, lots of filing  sanding and this is how it turned out .

Hello all thanks for following along and for the kind comments, bit more done today on the front end of the Minnie bought some brass to make the chimney cap week or two ago, I was going to try and make this out of copper sheet but thought it would be easier made out of brass,I ground the hss bits to form the shape and give it a go, lots of chatter later and some sanding and the result was ok.

Thanks Mal.
Title: Re: minnie traction engine in 2"
Post by: Jasonb on April 12, 2016, 07:39:49 PM
Your rims and tees look good Mal.

Talking of rivits are you just going to stick with two in the strakes?  In the larger scale 4 may be better. Also you don't need that deep a CSK for the strakes, it makes life easier if you use a ctr drill to give a 60deg CSK rather than the usual 90deg and not that deep.
Title: Re: minnie traction engine in 2"
Post by: mal webber on April 12, 2016, 07:55:56 PM
Hi Jason yes I was thinking of using 4 rivets per strake with a small plate  between t rings to imitate the joint, not on the book but think it will look good, thanks for the info about using ctr drill read this when you mentioned it on Joe's thread, thanks for looking in and your advice is always welcome.

Mal.

You have been looking too closely at my wheels!

(http://img.photobucket.com/albums/v156/jasonballamy/Fowler%20A7/PICT0340.jpg)

The plates do add a nice touch of extra detail and don't forget the spud holes as that saves a few rivits :) Just be glad that you don't have a set of castings for a Superba like I do as that should have 14 rivits per strake :(
Title: Re: minnie traction engine in 2"
Post by: mal webber on April 13, 2016, 02:06:16 AM
Jason have you got a build log going on the fowler superbr build , this is a ploughing engine I guess , is this the early one cylinder or the later double  , John Haining's  boiler drawings is what got me really going on traction engine building, still have a boiler that I started building years ago but far from finished .

Hello all, things have been a bit slow in the shed ,so only managed to weld the t rings in the rims, thought I would show some pictures on how I went about it, the blocks you see on the mill were to help hold the t rings straight and together trying not to get to much distortion ,I used a angle grinder to smooth the welds down and some sandpaper to clean it up a bit, last two pictures shows before and after I done this.

Cheers Mal 
Title: Re: minnie traction engine in 2"

Mal, nice little jig you set up there to hold the t-rings in place.  I'd be afraid I'd get weld splatters on my face plate if I did that.  In fact, I'm sure I would.  Looks like you did a very nice clean weld though.

Thanks for the step by step pics.

Title: Re: minnie traction engine in 2"
Post by: mal webber on April 29, 2016, 12:31:54 AM
Thanks for looking in Joe, Kim, the face plate had a covering of anti splatter so no harm done, bit more grinding on other wheel then a couple of days of making strakes and riveting.

So, I'm not much of a welder (if you couldn't tell :)).  Is "anti splater" a real thing? Or are you pulling my leg?  Maybe it a code word for being a good welder and not making a mess every where like I do?  :embarassed:

Anti splatter is real, it's a spray that stops the little blobs sticking where they are not wanted.
Title: Re: minnie traction engine in 2"
Post by: mal webber on May 01, 2016, 08:59:23 PM
Hi all, Kim anti splatter is real as Roger said very useful for keeping the work free of unwanted splatter good on the nozzle as well, Bob plenty of practice and you will get there, you will be surprised how quick you will learn on the mig, Zee thanks for looking in. here's couple of pictures on how i'am getting along with the rear wheels, I marked out the wheel rim ,then milled a length of 3mm [about 10 gauge ] bit of steel for the strakes, rolled it in work, then in the band saw to cut them ,they had to go back in the mill after as the edge had a angle on them.

Mal.

PS the holes that are drilled in the rim are for the dummy joint plates not the strakes.

You might have said earlier...but what is the size and material of the rivets?
Title: Re: minnie traction engine in 2"
Post by: mal webber on June 05, 2016, 10:52:37 PM
Hi zee, thanks for looking in the rivets are 1/8  mild steel 

Mal.

Post by: Kim on June 06, 2016, 12:23:23 AM
That looks amazing Mal!

It looks like 4 rivets per grouter (think that's the right word?).  And then 2 more for riveting something similar on the inside of the wheel?  The grouters on the outside, I assume are for traction. But tell me, what is the point of the diagonal pieces on the inside of the wheel? 

How hard has it been using steel for rivets?  Seems like it would be much harder than copper or brass.

I've seen that word, 'grouter', before in a couple of threads on traction engines and have wanted to say it wasn't right.
But with having seen it a few times I wonder if maybe it is the right term.

I have little to no direct experience with TEs but a lot with crawler equipment, new and old. The raised rib on a track pad segment is called a 'grouzer' or 'growzer' and I wonder if the TE would be the same?? All the model TEs I've seen
don't have a raised rib, only the pad. But I have seen raised rib growzers in pics of old TEs.

Most interesting.....

I follow all the build logs closely but the TEs get some extra eyeball time.

Looking fine, Mal!

I've understood the term "grouter" to refer to extended bits sticking out beyond the strakes for additional traction,
but don't quote me, I'm no expert!

Joe
Title: Re: minnie traction engine in 2"
Post by: Jasonb on June 06, 2016, 07:32:19 AM
Grouters is the US term, Strakes the UK one, both describe the diaginal strips on the rim for traction.

Additional traction could be had by adding "spuds" to the rear wheels, ploughing engines also used "cleats" on the front to give additional resistance to sideways pull. The holes where rivits have been left out of Mal's wheels is where the spuds would fit. Photo below shows spuds on the left, cleats on the right

Traditionally traction engine wheels were rolled from "T" section steel so on these wheels you would have needed two "T" rings, the joining plates on the inside are to hold these together. They were not always used, some engines just had the strakes to hold things together, others had a com,plete band on teh inside. Wider wheels may have had a spacer ring between the "T" rings or even a third "T" ring

Good bit of work there Mal, garden riveting is always a problem. My second engine is an agricultural and that will be on strakes. Four1/4in. MS rivets in each :facepalm2: I am not looking forward to that......must find out when the neighbours are away!
Title: Re: minnie traction engine in 2"
Post by: Jasonb on June 06, 2016, 07:53:27 PM
4 rivits per strake, you boys don't know how lucky you are, if I get round to making the Superba that has 14 per strake :(

Hi all, Jason thanks explanation on the grouters and strakes ,14 rivets per strake that would take some patience to get done, Kim the steel rivets weren't that bad if fact not that much different than the copper ones just had to hit them harder. Thanks for all the interest everyone  thought I would place the engine together again and take a picture or two just to boost my enthusiasm in the build and see if everything looks about wright .

Thanks Mal.

Looking good Mal!  Nice to have all those behind you, isn't it? :)

Your wheels must be more than twice the size of mine since your engine is a 2".  If it's not too hard, toss something in the picture for scale, like your hand, or a coke can.  (Or even a steel rule).  That'll help the size challenged, such as me :)

Looking forward to seeing progress on the spokes!

Hi all ,not much done this weekend just the wheel jig for the rear wheels , not much one for woodwork as described by the book so what I came up with is this, its a shame really after the wheels are done it will be in the spare metal pile.

Hi all , started on shaping the spokes that had previously made earlier on in the build, first eight done so the wheels are starting to take shape finally

Hi all, thanks for the comments, some more pics on the rear wheel (again) not much on the way I machined the hubs as they were done earlier on in the build ,one  set of spokes done on this wheel just the rivets and machine the centre out for a bronze bearing and onto the next one

Hello all, back on the minnie traction engine build after a long brake ,so picking up as i left it still on the rear wheels well finished the riveting on the spokes on the left hand wheel [ 190 rivets in total with the strakes ]  and now for the r/h wheel, my aim is to finish the back axle with all its parts  :)
Title: Re: minnie traction engine in 2"
Post by: Jasonb on November 26, 2017, 04:41:39 PM
Nice to see the extra detail of tie plates and 4 rivits per spoke, a lot of people just use two like the 1" model and no ties
Title: Re: minnie traction engine in 2"

Hello all ,well finished the rivets on the second wheel  so wheel riveting is finally done :pinkelephant:, then the wheels went into the lathe to bore the the centre out for a bronze bush to take the rear axle ,so both wheels are almost done ,next thing for me on the axle is L H driving centre and R h driving centre as i have the steel ready for them.

Comming on well, suppose it's the brake and winding drums next.

Luckily the minnie has quite a simple setup for the winding drum, the Fowler being true to original is a lot more detailed and even includes a foot brake to stop it over spooling when paid out. Plus you have no diff to worry about on the other side.
Title: Re: minnie traction engine in 2"

Hi all ,still on with the rear axle and I made the brake drum in the last day or so, again waiting for bronze bar to turn up for the centre bush on this part as for the winding drum,thought I would weight the axle as its feeling quite heavy at this point and it weights in at 18.5kg  40.8lb and still a couple of parts to make yet.

Mal.
Title: Re: minnie traction engine in 2"
Post by: Jasonb on December 30, 2017, 07:35:36 PM
You are making good progress

The weight is where scaling up the 1" Minnie design shows up, by comparrison this is the brake drum for the 2" Fowler

(http://img.photobucket.com/albums/v156/jasonballamy/Fowler%20A7/A7-brakedrum.jpg)

You can see it in position behind the spoked (not solid) final drive gear and diff.

Mal.
Title: Re: minnie traction engine in 2"
Post by: Jasonb on December 30, 2017, 08:00:49 PM
Or go the whole hog and put a diff in it :LittleDevil:

You don't get to see much of the final drive gear on the Minnie so it would only give a bit of a weight saving rather than look better. Infact you see even less on the Fowler as that has gear guards which cover it all up.
