Thread: Class 22 Diesel (next project)
24/10/2019 09:17:36

As well as the starter pack, I see from CuP,s website they also do 455 in paste form, recommended for small or awkward parts. I wonder if that would also be worth getting I can see how that could be useful but as I mentioned I,m new to all this.

Thanks guys, I will order a starter pack from CuP, sounds good.

I need to silver solder a hex head bolt to a 3mm steel plate, assuming thats possible of course..?, having no experience with silver soldering I would appreciate some guidance on suitable solder and flux type.

I have put the traction engine to one side for now to put some time into the class 22, the loco is a much quicker build and it would be good to have it finished for late spring next year.

I made up and fitted 3 frame spreaders, of which the 2 end ones also serve as buffer plates. The chassis is very simple 2 x alu angle side beams 2" x 1" x 3/16", 2 x steel bogie mount/swivel plates 3" x 1/2", 3 spreaders 2" x 1,2" alu bar. The top of the chassis beams will have 3mm steel plates connecting it all together, simple but strong.

Just started making up some detail parts for the bogie side plates plus the sides of the chassis beams.

I am impressed Jason, I would never have imagined a one piece crank coming out of a piece of bar like that.

Thanks Jason for the explanation and drawings.

Jason, I am intrigued by the throttle adjustment which I think you said was operated by revolving the fuel jar, can you explain how that works.

19/10/2019 09:42:23

The head turned out well Jason and it really does look as if its come from a casting.

Four hours with the files and emery and its as good as it gets but I,m happy with it, its not perfect in places but thats ok, gives it a bit of a casting look. I have gone with 4BA for the fixing bolts and the mounting holes in the saddle are tapping size ready for spotting through once I know its position on the boiler.

I am a big fan of 638, it cures quite quickly probably too quick if you have adjustments to make but in some assembly situations the speed can be a bonus. It has good gap filling up to 0.25 mm if I remember correctly and the cured joint is extremely strong. For permanent fixing and retaining of parts 638 is the one I always use.

Jason, out of interest what material are the timing gears cut from, also do you cut each position to full depth before moving to the next or do you work around the gear gradually increasing the depth.

Excellent Jason, I do enjoy your build threads mainly because I usually learn something from them as well as admiring your work of course.

Great stuff.

Thread: Electric Traction Engine

Thanks Jason,

I have enjoyed making it, though a couple of areas had me a bit challenged but just down to a lack of experience I guess. For the saddle fit to the boiler I have gone with an average of what I measured from the tube, the tube looks fine but its not so true when measured. I havnt checked yet but does the cylinder to boiler have a gasket I,m assuming it does and that will help with the fit.

Just about there with the one piece cylinder block from bar stock, a couple of angles to mill on the left hand edge of the saddle and then hand finishing. I am glad I had a go at doing this, a few lessons learnt I think and if I had to do another one there are areas which I would do differently. I will be away tomorrow for 3 days so wont get back to the shop until Friday when it will be a case of getting the files out.


Thread: An interesting repair to an Hour Wheel

I dont think hideous Michael and I agree quite clever really.

Looking at it from just the tooth side and not knowing anything about clocks I would have probably glanced at it and thought it designed that way and served a function for each revolution of the wheel.


Thread: The Workshop Progress Thread 2019

Yep its working now, and what a lovely little engine. I love the sound of it very nice indeed and good that you got it running so quickly.

Thread: Electric Traction Engine
12/10/2019 10:28:19

I have probably taken the long and winding road approach to making it but its worked out so far and its getting there slowly.

p.s. The notch along the length of the left hand saddle is still outside the rad (just) so should be ok when it comes to hand finishing...smiley

Jason, I looked at the R C Machines link you posted on another thread. In their "flying" wheels range they do a partly machined 6 inch wheel for 29 euros, looks really good to I cant buy a C/I blank for that price.

Dont think I will need the rotary table just working around the radius by eye, should blend in with a file ok.

The largest lump I have had on the little mill so far, even had to remove the vice jaws to fit it in. Hopefully a one piece cylinder will come out of it. First job reduced the height by 15 mm with the flycutter, faster than back and forth with an endmill. I do most of my fly cutting now with an insert tool robbed from the lathe, works really well. The radius is 45mm which is about as much as I would want to go but it worked, dont think I would go that large with steel, well not in one pass. The slight tool out of balance vibration disappeared above 1500 rpm so I ran at 1750 with 0.030" cuts which sailed through it. I dont have any GT inserts, maybe I should get some and use those for ali.
