• Hi all and welcome to TheWoodHaven2 brought into the 21st Century, kicking and screaming! We all have Alasdair to thank for the vast bulk of the heavy lifting to get us here, no more so than me because he's taken away a huge burden of responsibility from my shoulders and brought us to this new shiny home, with all your previous content (hopefully) still intact! Please peruse and feed back. There is still plenty to do, like changing the colour scheme, adding the banner graphic, tweaking the odd setting here and there so I have added a new thread in the 'Technical Issues, Bugs and Feature Requests' forum for you to add any issues you find, any missing settings or just anything you'd like to see added/removed from the feature set that Xenforo offers. We will get to everything over the coming weeks so please be patient, but add anything at all to the thread I mention above and we promise to get to them over the next few days/weeks/months. In the meantime, please enjoy!

Farm Boy Hit and Miss engine

Just a couple of small parts made over the last couple of days. I did waste over an hour looking for my 1/4" collet which seemed to disappear into thin air, workshop gremlins at work to only find it right in front of my eyes sitting on the lathe why it should be there as I last used it on the milling machine.

Anyway the two parts which enabled me to test the gears on the frame(rubbish video but you get the right idea) a bit awkward using one hand as I was steadying the camera with the other

Turned the main body but left it on the main stock as there are other things that need doing to it that require the extra material to hold it.

After the turning I made the two arms followed by cutting a couple of slots in the turned part, still need to drill two holes that is why it is still set up in the milling machine touch wood that will be tomorrows job followed by turning a couple of pins ready to silver solder the arms in the slots that will be another thing that I have never done before I am alright soft soldering.

Arms only resting in place to show how they go. Milling cutter is set on centre ready for tomorrow

Best of luck with a new experience.

Silver soldering is one of those simple functions that are very satisfying when completed.

Biggest problem on an item like that is getting the heat into the large heat soak of the body so that you get an instant wicking of the solder when you touch it to the fluxed joint.

I have a little hearth of fire bricks and some flame resistant/heat reflecting fibre tiles.
I often position a slave gas torch to provide 'soak heat' on the bulk of the item and use working torch to control the joint area final temp.

I do have a small hearth knowing that at some time I would need one. It will take quite a bit of heat in the main body of this assembly I may cut it shorter leaving enough to remount it on the lathe later. This will hopefully help with the soldering. The slots called for a 0.128 width so I went in straight away with a o.125 cutter as quite often that will cut over size very slightly and there does seem to be enough room for the solder to wick in to the joint

At least you won't have to get as much heat into it as I did with these Tool Rests shown in UKW thread from 2020
 
The governor parts pile has some more parts added to it all small parts but seem to take ages to do even if they are simple still some more to make. I have not yet soldered any parts as there are a few more that need hardening so will do the soldering and hardening all at the same time weather permitting as it is raining here.
The brass pins with the thread on the left are 1/8" diameter to give an indication of size the split pins that will be used on the silver steel pins are 1/32" to fit in the tiny holes

I have managed to do some more between having to buy and set up a new compter as well as getting the car passed a MOT.

Any way a few more parts some for the Govenor assembly and some for the exhaust valve assembly.


Govenor partts

Exhaust push rod assembly

The govenor assembly operates the exhaust assembly once all completed as well as the ignition system.

A general view of both assemblies some need to be silver soldere together I will ddo them in a batch that is why they are still in pieces to give an idea of sizze the two brass balls are 5/8" dianeter

The box is slowly filling up with parts this stops bits from going missing while working on other parts

New computer set up, car Mot'd and more bits, Christmas has come early! :)

Nice.
 
The new computer’s spell checker is not working ;) :)


I’ve little idea of what half those bits do Derek. How far off are you from assembly?

The computer is a joint present for me and the wife from ourselves. The car did not need anything doing to it not bad for a 25+year old/

That was me with the spelling and missed the underlined mispelled words.

Still a few bits to make yet the main ones being the two flywheels that need turning and the fuel mixer assembly.

Then I need to sort out the ignition system, base board and fuel tank.

I may be able to do a small assembly soon but then strip back down to paint.
 
Then I did make a couple of support brackets for the valve rod assembly which are 0.600" long and to make life easier made a small jig to cut the angles on each end after refreshing my memory with a little trignometry. I don't think much will be done this side of Christmas but if any then I will post as and when there is any progress.

The jig with the parts still needing a little clean up then one with it in the vice showong how the parts will be sat in it and finally with it all secured and the angle being machined. I was appy how the jig performed. Just to point out the jig is a fraction narrower than the part so it grips it while machining

I machined two little back plates which I made a simple jig as they are only 0.025" thick and 0.250 wide I did them both at the same time.

Spacer (1).jpg

Spacer (4).jpg

Three steps forward and one back seems to come to mind.
Then I desided to start on the fuel mixer the main body was completed out of a 0.500 hex stock which went well. I then moved onto the little mixer bar that fits into the body drilled and threaded one end and drilled the small centre hole and this is where it went wrong O cut it over long and turned it around in the collet chuck so that I could machine to length being only 0.125" diameter and a 2-56 thread inside the obvious happened it snapped oh well I will machine to length first next time before drilling and tapping again.
The grub screw in the mixer need either a shorter one or the one I have needs machining shorter, thats for another day

No photos of the oops moment only the other work completed.

Nice. Tiny.

Just finished the fuel adjustment needle an :cry: d that is even smaller. I will get a photo tommorrow
 
Glad to see things progressing, you'll be wanting a watch makers lathe for the shed if you carry on like this.

As promised a couple of parts for the fuel mixer

The fuel adjustment screw. Now where did I put it

fuel mixer smaller parts (5).jpg

Oh there it is

fuel mixer smaller parts (7).jpg

Next is the spray bar that the adjuster fits into I had to drill from both ends and a smaller one right through this is ny set up to get the correct drill depth one end is also threaded 2-56unc

the parts showing the main body, spray bar and adjuster with a tape for scale. The spray bar I need to set upon the mill to drill a cross hole with a number 76 drill (0.0197" or 0.50mm) I have left one end at 1/8" diameter until I get the fuel pipe from the fuel tank once I make that

The fuel mixer assembled except for the hole that needs drilling as well as a grub screw the right length

Fantastic thread. Well beyond my skill level.

Everyone has a skill most just have not uncovered it yet :lol: There are many things that I have not yet tried a bit like this build as I am learning with every step

I'd have no chance getting it past my wife either :lol: I did some favours over the years for an old guy we knew and out of the blue he gifted me the lathe and accessories, to say I was astonished is an understatement

Seriously a very nice gesture by him

His only stipulation was that I didn't sell it which of course I wouldn't certainly unless I was physically unable to use tools. I know what you're going to say "just give it FOC" :lol: - NOPE.

The couple lived about 20 miles away, next door to my inlaws so I would cut his hedges when I did theirs, fitted a new cooker hob, new door locks and general stuff for them but charged only for materials as we were friends and they were getting on a bit. They were very well off though and I know he used the lathe probably no more than a dozen times so it was extremely generous of him.
 
Cabinetman":4kv8ggba said:
I imagine he almost got as much from giving it to you, - someone who will use it and enjoy it, as you did receiving it. So enjoy!

I think he probably did Ian. He had two sons neither of whom had any interest in his tools. Sadly the couple passed away a few years ago and now I'm the one who's getting on a bit. :lol:

I m enjoying this WIP, some interesting techniques and amazing skills.

Thank you as for techniques I am learning as I go they may not be the best way but they work for me.
 
Been busy with other things since the last post. I have started to sort out the garden as well as look after the wife as she was not too good (all OK now) which meant housework and cooking which I love anyway(cooking that is)

Anyway had to remake the small fuel delivery bar as I was drilling it with a cross hole and messed it up as the bit was a #76 which is quite small. Now that is all done, I can make an elbow to go from the mixer to the head
Some photos of the fuel mixer with the bar which is only 1/8" diameter so that gives an idea of the cross hole size.

Really super stuff, you’ll be making clocks next haha.
Ian

Thank you. Too many gears to cut in clocks but I have enjoyed watching a guy on u tube called Clickspring a master at making mechanisms especially the clock he made.

I will stick to this engine and the Rob Roy loco I am building
 
Because I have been busy with other jobs I only manage to turn the elbow blank in preparation for it to be machined, bent and silver soldered (I did bend the first one but had problems so started again) I will heat this up before bending as I am only milling a V in the middle (on the line marked in the last photo) and leaving a small amount left this will help keep it in line and also make it easier to solder.


Tube turned ready for next set

Loctited to a mandrel ready to be machined

Set in the mill ready for tomorrow to have the notch cut. Hopefully get some more photos tomorrow as I progress.

elbow construction (11).jpg
 
The last part of the fuel mixer assembly is the elbow. Not having one, I thought I would have a go at making one which will give me the chance to do some silver soldering, as well as a very simple start to fabricating.

I started with 1/2″ brass bar(see my previous post) and turned the ends and centre section as needed, with a piece of steel made a quick and simple mandrel which I loctited on and clamped at a 45deg angle in the mill vice and notched out before heating to cherry red and bending to form the angle. I thought this was easier than cutting it into two parts and trying to keep it lined up while I soldered it.

I filed the outer corner of the bend as it looked wrong being left with a sharp corner

The final photos show the last step.

Lovely work
 
Thank you guys except for the replacement grub screw which is too long the fuel mixer assembly is now complete.
I now need to go through the plans to see what other small parts need making before starting on the two flywheels.
 
Never mind a whole engine, I'd be really pleased with myself if I'd just managed to make that lovely little elbow!
