Brian’s 1″ Minnie Traction Engine

Coming along nicely Brian, good work

[Brian AbbottParticipant @brianabbott67793]

Thank you Derek.

Just waiting for some more 10ba bolts to arrive, i can then bolt everything tight and check for true.

Riveting and soldering then.

[derek blakeParticipant @derekblake72550]

Out of interest what part gets soldered? I bet that’s hard to keep neat.

[derek blakeParticipant @derekblake72550]

Wheels look lovely and neat.

[Brian AbbottParticipant @brianabbott67793]

Hello Derek.

There are inner and outer covers which get soldered onto the hubs, fixes everything together.
When I soldered the rear hubs I used a soft solder paste, worked ok but i had an issue with corrosion from the flux.

It has been suggested that I try an epoxy glue instead of solder but I’m not sure.

Slight change of plan at the moment as I forgot to cut the slots that imitate the tyre tread so that’s next on the list, then solder them up.

[derek blakeParticipant @derekblake72550]

Hi Brian

yes I would probably you epoxy myself, as flux can seep out over time but I’m no expert.

i look forward to the updates, keep them coming,

Derek

Hi everyone

Just wondering when you build the rear wheels is it best to rivet the strakes on first or do the spoke and hubs first?

George

[JasonBModerator @jasonb]

Strakes first while it is easy to get to the rivits

[Brian AbbottParticipant @brianabbott67793]

I did mine before, as Jason said it's just easier.

[Raymond GriffinParticipant @raymondgriffin40985]

Hi Brian, I don’t have the expertise to compare the relative merits of solder versus JB Weld. It seemed to me that the joints are not heated or highly stressed and are riveted. For me, joining metals with epoxy has always been successful provided that the resin is well mixed, the surfaces to be joined are roughened and that the components are kept warm to facilitate polymerization. I have seen other reports or flux residue causing corrosion.

Your wheels look nicely made. Ray

[Brian AbbottParticipant @brianabbott67793]

Well i've done it now.

Decided to stay true to Mr Masons book and soldered the first one.

Time will tell.

[George JervisParticipant @georgejervis86082]

Hi everyone,

I am about to start making the front wheel hubs and cannot for the life of me find the information and measurement for them? I have the book by L C Mason and the original plans for the 1in minnie but find they a vague. Looking through the box of casting I have I have identified almost every item I need but not sure if these are the casting for the hubs?

George

My picture is he my album and I'm not sure how to put it on here thank you

[JasonBModerator @jasonb]

can't see the pic in your album but thought they were just cut from brass bar. Page 106 has the drawings

 

EDIt, Seen the photo now you have uploaded it and yest they will turn into the front wheel hubs, all three bits in one casting for each wheel.

[George JervisParticipant @georgejervis86082]

Hi Jason B,

That makes sense now, I'd asked a couple of friends what they would be for and they were not sure either, But now I can see how they will be made

Thank you for your help

George

Very nice work Brian.

[Jeff DaymanParticipant @jeffdayman43397]

Wheels are looking great Brian!

[Brian AbbottParticipant @brianabbott67793]

Thanks both.

Small victory tonight, finally sat on its wheels.

Hi Brian

Great work, looking great 👍

[Brian AbbottParticipant @brianabbott67793]

Hello all.

Just in the process of turning the Chimney from a solid lump of aluminum.

Can anyone tell me.

Is the bore a continuous taper or dies it run parallel for the first 17/32 at the top end ?

Thanks

[JasonBModerator @jasonb]

I ran mine as a constant tapering bore.

[Brian AbbottParticipant @brianabbott67793]

Thanks Jason.

[Brian AbbottParticipant @brianabbott67793]

Hello all.

On the base of the chimney there are 4 – 8ba bolts attaching it to the chimney saddle.

Spaced equally on a 1 3/16 pcd these seem really close to the edge.

Is this correct ?

[norman valentineParticipant @normanvalentine78682]

On my Minnie I bored it parallel but stepped it. At first it looked horrible as you could see the steps , a quick spray with Matt black paint hid it, I don’t intend to steam mine but soot will do the same job on a working model.

just looked at mine which I assume I did to drawing and they are quite close, the hex heads come right to the edge of the flange but there is not much space between them and the vertical part of the chimney base so you could not move them in much maybe only 1/32" off the PCD.

[Brian AbbottParticipant @brianabbott67793]

Thanks for the reply's

I think i am going to bring them inboard and use one size small heads..
