So, onto the cladding. I don't think I am going to enjoy this. Sad

Started on the cylinder cladding and after a lot of fettling I have pretty much given up on fitting the brass finishing strips. In my view, it looks ok without but may ask STW for a new set at a later date.

Onto the boiler cladding and test fitted the first 4 sections but do not intend to paint until I have more of the components attaching through the cladding, then I can file to fit if required.

For the rear cladding section with the manhole cover, it looks to require a fair amount of trimming as approx. 5mm too long.

Was I meant to file down the protruding stay ends on top of the boiler as they impede the cork sitting flat and the fitment of the manhole cover?

Back on the scene eventually, learnt a lesson there on moving during a Pandemic!
Treated myself to a Tap and Die set off Fleabay but haven't got a clue how to use it, tried to get the thread size of the M3 hex screws to clear the paint from the threads of the plates but couldn't find the right Tap.

Pity you didn't get an answer for the filing off the protruding stays, would have been nice to know, what did you do in the end?

Looking forward to receiving my kits again:D

I didn't file the stays on the boiler just put the cork over it and fitted the cladding

I've lowered the stays a little but have yet to fit the cladding properly.

With it being summer, gardening and decorating the outside of the house have become the priority, so all work has stopped on the engine for the time being

Finally got to make a start on Kit 11a&b, All went together well with the piston moving freely but when i put the fingers on the Crosshead and bolted them up the piston was fixed solid, added a slither of Kitchen Foil as it says in the instructions to no avail, eventually i had to add a washer between the fingers and the cover to get any movement. Has anyone else had this problem or is it just me?

Wait until you get your wayshaft bracket and then sort out the guide bars I had to use some drink can folded to get correct shims so the crosshead moved freely

Just got out the garage after dry assembling the cylinder block etc, all gone well but a bit confused about the statement in the instructions about the elliptical recess for the whistle, don't know where that is and i have to put PTFE tape on these studs. Are these all that needs PTFE tape and which studs do i put the Foliac on? talking of studs is there any reason why some of the studs don't go in as far as some others?

When I attached my cylinder block, it was also the case that some studs went in further than others. I just went with it as they were secure and I did not want to cause any damage such as stripped threads in the boiler. You can trim them down with a Dremel later anyway.

I applied liquid ptfe sealant to all the studs (available at Screwfix)

Last couple of days I have got the crank, conrod, flywheel and cylinder all co-operating and as has been said I would not worry about getting the guide bars to allow piston movement until all the components are mounted on the engine. I ended up using 2 pieces of coke can on the top guide at the cylinder end to get all moving.

Also I lapped the crankshaft with some medium valve grinding paste and the conrod onto the crank. I understand Yellow Timesaver Lapping paste is best for the job. However at £13 + £8.50 postage for a small pot, I gave it a miss and made sure that I removed all trace of the valve lapping paste.

Now with flywheel attached I can turn it over fairly easily, so will hopefully bed in fairly quickly once in steam

Only drama I have had is snapping the brass oil filler screw on the conrod. Too heavy handed with the spanner  Embarassed Hopefully Will is dropping one in the post

Lovely, Thanks for all the info, a trip to Screwfix is in order. Don't you think we might have to remove things at some stage so Dremel the excess on the studs might be unwise. just a thought!

I'll take the risk. Can always replace studs. Important thing is to leave enough thread proud to lock 2 nuts on to aid removal

Current progress:

A little more progress tonight having received the next kit last week.

Struggling to understand the diff lock and how it works but hopefully it will become clearer as I complete the assembly.

So in normal running is the diff lock engaged or disengaged? I am assuming that engaged has the lock lever pushed towards the diff?

So when disengaged should the 4 prongs on the lock ring (BU21717) disengage fully from the Compensating Centre (BU21704)

I misread the instructions and probably took a little too much off the prongs as I misunderstood that they should of been filed down only if they protruded from the inner bevel (BU21701) when diff lock withdrawn (disengaged?). So they are now a little short and I am worried they will not engage or disengage positively.

Will@STW - should I look to get a replacement? (BU21717)

OMG not looking forward to all that. Received Kit 17 myself last week but nothing i can do with it because i haven't received the boiler yet! so plenty to go at eventually.

Hi Nick

How short are the prongs? It depends on whether they go into the compensating center when the diff lock is engaged.

The diff lock works by pushing the prongs into the compensating center through the inside bevel gear, thereby locking the bevel to the center so that neither can turn at different speeds. This action locks the whole diff assembly together so that both rear wheels turn at the same speed all the time, and are not independent of one another as they would normally be. This gives the engine more traction in slippery conditions, however when turning, the outside wheel (so for example when turning left this will be the right hand wheel) will drag slightly as it tries to go a further distance than the inside wheel but without being allowed to turn faster as there is no differential doing the job of separating it from the inside wheel. So naturally in normal conditions you will need the diff lock to be disengaged as normally you want the diff to do its job.

I cannot think of any situation where you will require the diff to be locked on a 2" Burrell. They are (relatively speaking) quite light, and in situations where they will get stuck you would normally get a couple of people to lift them out for you, and in situations where that is a problem you are unlikely to drive them around anyway.

Many thanks

Thanks Will for the clarification.

So basically on a 2", you would always run with the diff lock off and pinned in place i.e. lever to the left as you look from behind?

So, as long as the prongs do not protrude through the inner bevel (BU21701) when the diff lock is off, all is good?

Hi Nick

Correct, when the lever is across to the left (from the drivers position), the prongs are pulled out and the diff can do what it is meant to, and if the prongs don't go all the way through the inner bevel when the lock is disengaged then you shouldn't have a problem (if the lock is disengaged and does go through the inside bevel and into the diff center then that is when problems can crop up, as it will never unlock).

Many thanks

I will also look at adding that explanation of how the diff lock works to the instructions so that people in future have a better understanding of what it is they are building (that's one of the reasons people buy our kits is to understand how it works before putting a fire in).

Many thanks

I think that is a really good idea Will.

Being a complete novice to the world of traction engines, any additional info is much appreciated.

I have put it all together now but the diff is not able to rotate a full 360 degrees, so will strip down and examine the teeth to see if any fettling is required. Currently more like 90 degrees before it locks solid.

Also if gears fully tightened to shaft all becomes very tight. So presumably some easing to be done

I also filed down the brass tender trim slightly as the inner bevel gear was rubbing (see pic, don't seem to be able to post right way up)

Following some great advice from SteamHuffy, all seems good.

I placed a thin washer at the other end of the 2nd shaft between gear BU21715 and the end washer BU21722, thus allowing a little more length for the gears and diff at the other end.

All seems good with no play evident and diff is free to rotate.

Not had time to write anything for a while so thought i'd better update.

Got a nice parcel at the beginning of the month,
New boy on the block! - Page 5 Img_4010
so set about adding all the bits which where lying about, all went well except for the easy job of fitting the Fire Door had to add washers to where it connected to the bosses on the boiler which made the screws to short to attach them, Will soon sorted me out with longer ones, thanks Will.

Had to laugh at the line in the instruction " The Fender is simply slid over the protrusions and bolt on" 3 days of "Fettling" meant it fitted right but the time painting was a bit of a waste because of my own clumsiness with the Dremel and spanner slips, will have to sort it out at a later date.

Had to modify the Ashpan flap a little so it opens over the nuts holding the flap on and the pins holding it all on the boiler where too small but all okay now.

Just the fitting of the cladding should finish it off nicely. Very Happy

Looking forward to what comes next!!
