I don't think that's a good excuse.  Scratchbuild.  You clearly are slacking!

Ha Ha, very funny.  

I bet I if we did it against the clock I'd still be winning.  Can't wait to see your blog posts or workbench thread on building a Finney M7....  Maybe you'll have it finished for AP and I can see it then...

Thanks!

Mike,

Any updates in the offing?

Duncan

Excellent work. Look forward to the next project.

Progress of a sort on the 43xx... I have now got a set of comet cylinders, slide bars and cross heads. The measurements are quite interesting. The comet and perseverance cylinders have the same em frame width, 15mm. The distance between the inner faces of the comet slide bars is just over 26.5mm, while the distance across the outer faces of the crank pin nuts is 25.55mm. The issue I think is in the width of the slide bars and cross heads. The Perseverence ones are 2.5mm overall, while the comet ones are 2mm. So I think that I might now have about 0.25mm at least of clearence.

I'm at the point where I think it's going to get a dunk in boiling water to reduce it to its component parts. I'll be taking a very critical look at the fit of the saddle and boiler so thanks for the tip.

Thanks!

Gareth and 'Horsetan',

It's an early Perseverence. The combined 43/61xx chassis... The spacers are em. The cylinders are on a separate stretcher and there is lots of room between the rear wheels face and the frames, just not the front face and the cross head.

Hi Mikkel,

It's a Sutherland one! Whilst I'm sorry you're having problems with it too, I'm also a bit relieved as it suggests I haven't done something bloody stupid...

Regards

Duncan

Did you have to move anything out on the Jubilee to get room behind the front drivers and crosshead? 

Looks a great job.

 

Mike

No. The crank pin nut was turned round to give more space and there is almost nothing between the connecting rods and the return cranks etc.

D

Good to see you keeping out of trouble. The more non-GWR P4 engines the better!

You're pushing your P4 luck...

D

Perhaps Castle, of this parish might be able to advise.

Research funding is always good. And it would be interdisciplinary too - chemistry, environmental sciences, and history. It would tick ahrc and escr funding boxes... Now all I need is tenure somewhere...

Dear Mike,

Thanks!

Duncan

Yes you're right, technically the O5 has DC 1 brakes, the Thomas and side lever ones being undiagrammed, but it remains a handy catch all for the 4 plank family in pre double sided O21 days.

It will also get a load, probably stone.

Hi Grahame,

The red is halfords red oxide primer. I've found precision paints too brown so added a little China red.

The weathering used light rust, light red, light mud, light grey, orange red.

The only trouble with the halfords red oxide is that press fix transfers don't stick to it so I used klear polish to give a gloss finish where the transfers were to go. Make sure you leave it to dry thoroughly or the transfers still won't stick!

Regards

Duncan

Yep!

D

Ian,

Inspirational work.

Duncan

Glad to see more developments in the Farthing series. Could you post on using foam board for baseboard construction?

Drduncan

I'll try anyway.

D

Incidentally, I have no idea why the pic of the cattle wagon is upside down. The original isn't!

I have been having sagas with transfers lately. I normally use press fix whenever possible but have been having trouble persuading them to stick to the red body colour when using carrs transfix, even on a layer of johnsons gloss clear. Had even more problems when using the Fox's gpv transfers and ended up only using water. Will try microsol but as it's had a light varnish I'm not hopeful.

D

Dear Mike,

Very interesting developments! I'm most jealous and very tempted by BG myself-especially given I seem to be producing more GWR red wagons than grey to run on Hope Under Dinmore (much to the dismay of the LNWR fraternity and the sage of Fareham who are wedded to grey wagons!).

If anyone plans to visit expo em do come by and say hello, I'll be demonstrating messing about with plastic wagons in ways the designer did not intend...

Drduncan

Thanks! The dome just pulled off... There was a bit of filling to do, which I think can be seen in earlier photos. The replacement done was a brass Alan Gibson one with the mould lines filed away and then polished with fine wet and dry before gloss varnish.

How are you doing the round topped version? I have one in progress but stopped work for lack of measurements.

Regards

Duncan
