Thanks Jason

I am almost there parts wise, finished the oil cups and the flywheels have arrived so once machined parts are complete.

Jason,

I have read through the Kerzel drawings and build notes and I think I am quite happy with them, though I did note that Kerzel does not recommend the engine as a first time IC, I say I,m happy but I could be missing something of course.

I did a search this site but couldnt find anything on the forum here and wondered if any of the forum members have built one..?

If I go with the Kerzel I think I would go with the Julius doubled up 38mm version, its quite a good size (7 inch flywheels) but all possible on my lathe and mill. I just thought that I may as well be building the larger version as the smaller one or am I being a bit over ambitious.

Ron

Thanks for the links and drawings Jason, I will have a good read through them.

Having had a quick look the doubled up 38mm Kerzel grabbed my attention as a good size but on first glance the drawings look a bit daunting though all the information is there of course.

The order of my projects/builds has changed somewhat, my club have cancelled all track meeting dates until further notice. We can still use the track (minimum 2 people) at our discretion but I can see days when there would still be a number of people turning up and I dont fancy that. I can also see that this season at the track is lost or at best very late in the year before back to normal so the need to finish the class 22 loco does not have any real urgency about it.

So having enjoyed the little oscillator and enjoying the Jowitt even more when I have finished the Jowitt I am going to fit in a 3rd stationary build. I havnt decided on which engine yet but I do fancy having a go at a hit and miss which leads me to a question for Jason.

Jason, is there a basic hit and miss design that you can think of that size wise would fit my lathe and mill or one that maybe could be scaled to fit, also one that could be produced from bar stock would be good as I do enjoy making quite shapely parts from bar, the Jowitt cylinder for example.

Thanks

Ron

My take on an oil cup, not quite the sexy shape as on Jasons drawing but I am quite pleased with it. I shaped it by hand using files and emery.

Playing catch up so was up bright and early and managed to get some more done. The cylinder end cover, a pair of eccentrics (need a finishing cut) made and fitted the small end bearing plus made and fitted the wrist pin end pads.

Only the oil cups and flywheels to do and I will have all the parts.

Thanks Jason, will get myself some.

I have a pair of Perseus flywheels on the way, Chris Gunn was good enough to sell me a pair. You probably know but Chris built 4 engines and had a fifth pair of wheels left over from a bulk buy.

Ron

Jason, whilst I remember you mentioned recently not using too heavy an oil on the engine, what type do you recommend.

Ron

Life gets in the way sometimes but managed a few hours in the shop yesterday and produced the valve parts.

I used brass for the cam followers and lock nuts as I had 6mm hex on the shelf but no steel hex. I cut a pair of springs from what I had they are 5.5mm dia instead of 6mm but they are correct in wire gauge so hopefully ok. I slipped the inlet valve into the seat and held it vertical so it was just the weight of the valve resting on the seat and I couldnt blow through until I lifted the valve it so that seems good.

Very good, I do like the radiused blade tips looks much nicer and in keeping with the engine than square or just slightly curved.

I meant to ask Jason did you make the fan it looks like copper, impressive to.

You do turn out nice engines Jason, this is another one I like very nice indeed. Sounds good and I dont think the tickover is too fast. I like the cooling fan and its drive, thats fun and I know I keep repeating myself but I do like the shapes in the RMC castings, different.

Ron

One tool I would recommend (from experience) which should be fine in MT2 and your available power on the TS is the 25mm - 2 insert end mill from ARC. I use one on my small SX2P (500 watt) R8 mill. Since getting one it is probably my most used cutter, 1604 polished inserts for alu and Tin coated for steels. Available in MT2 at £29.98 and I have found it to be excellent.

Well it obviously didnt meet with your approval Dave but it met with mine..

Silly conversions, what silly conversions..? I am quite happy working with metric or imperial and most of what I do is metric, my locos are metric. When it comes down to tight dimensions/tolerances etc I instantly see thousands in my head better than I see parts of a mm but that is just me, hence an imperial micrometer.

It didnt need to be checked against slip gauges but I thought I would and I would have done the same for a new measuring tool.

"Shame on me" and "why risk it" well having spoken to the previous owner I knew it would be good and at £7.50 what is there not to like.

Ron

Still some bargains out there, I picked up this 0-1" Moore & Wright for £7.50. It was pretty dirty when it arrived but a really good clean got rid of most of it though not all of it. Its very smooth with a good ratchet, the mating faces are as good as new and its spot on zero and accurate to a few slip gauges I tested. Came with a case the spanner and a clip on pointer/indicator, not bad for less than a tenner.

Thanks guys and thanks Phil and Bill for the pointer to the MetalGuard I will get some on my next ARC order.

Ron

Thanks Emgee, I missed Jasons explanation also, sorry guys.

Having just given all the brass on the engine a good polish is there any means of treating it to maintain the finish. I was thinking of some kind of clear lacquer or does that breakdown over time.

There are certainly some nice models listed, locos, traction and quite a few stationary. I realise the prices are guide only but surprised how low some of the stationary models are when you consider what goes into some of them. I guess it must be down to how much or how little demand there is for them.

Oops, should have read the thread fully, Bill mentioned this in his post.
