I will be making one of those as soon as I get material and spare workshop time, but hopefully not far off as I think that will prove very useful for this buildGTB wrote: ↑Wed Apr 10, 2019 12:54 pmAs it happens........
I used some off-cuts of BMS bar I had in stock, as the only critical dimensions are the dia. of the hole for the tap and the position of the grub screw. I wasn't about to turn the whole thing out of solid, so the grip is a small piece of 3/4" BMS knurled and drilled separately and then pressed on.
The sleeve is the bit gripped by the chuck and this one is 11mm od and 50mm long, with an 8mm hole drilled through it.
The body is another piece of 11mm od about 60mm long. The spigot is 30mm long, turned down to be a nice running fit in the sleeve. The grip is a piece of 3/4" dia., knurled, drilled 8mm and cut off at 10mm long. The tap end of the body is turned down for a length of 18mm to be a press fit in the grip.
My 10BA, 8BA, 6BA and M2 taps all have 1/8" shanks, so a hole that size is drilled in the end of the body, deep enough to take most of the tap shank. The grub screw is M3, positioned so it engages a flat on the tap shank, that way when loading the tap, the grubscrew only needs to be nipped up enough to stop the tap falling out, as the flat stops the tap turning in the holder.
I've not seen anything remotely similar available commercially, but it's worth it's weight in broken taps........

Graeme

Re: Another Wild Rose Project
I had a very sneaky workshop visit today, had to work fast as it's the wife's birthday and she went shopping so while she was out I popped in there. I managed to cut down a new cylinder holder, mill it out, drill it out and even solder it to the existing cylinder.
I still need to put a flat edge on the sides for the slide bars to bolt to and I also need to shorten some of the screws as they are a bit long at the moment. Small steps all in the right direction, at least it all fits together at the moment

Re: Another Wild Rose Project
Indeed we do, it's good to have some sneaky time in the workshop
Well today. I finished the cylinders, or at least for now as I have a suspicion that I am going to end up remaking the back covers again as there are some issues that might stop things happening down the line, we shall see and I remain hopeful that everything will fit later
So, I made the threaded section that screws into the rear cylinder cover and the piston rod comes out of, that all went well. I cut down the 10ba screws that were slightly oversize and screwed all the cylinder covers on properly. I managed to get some proper 4mm silver steel for the axles as I originally only had mild steel so I cut those to length and popped all the running gear onto the to ensure they were a good fit. I also manged to 1/4 it up and everything seems to run fairly smoothly considering they have no oil and zero running in. Pretty happy with efforts so far, but far from perfect, lol Ignore where the grub screws are as one of them slipped and drilled off centre, but it does not affect the actual crank arm and it 1/4'rd up fine, just have to not do it on the grub screw position.
And here it is with the boiler plonked on top of it, just to see it look a bit more than a flat chassis really, lol

Re: Another Wild Rose Project
How I wish I lived nearby and could nip round for a visit to see this model being built. I've always wanted to build my own steam engine, but the lathe and mill work seems so daunting. I'm enjoying this thread. Sometimes when I see how easy this stuff is for guys like Tony Bird for instance, well it's easy to say "well I'll never be able to do that". But watching a relative newcomer taking a challenge the way you're doing- somehow that's more inspiring.

Re: Another Wild Rose Project
Thanks Keith, your post makes me proud of my work and I post up these type of threads to inspire others, we all start somewhere and if someone sees my results, and errors, it might give them the incentive to take a chance and start doing more. My pile of "out take" bits is increasing, but some are being re-purposed as I go along, so things are not always a total loss, unfortunately the expensive bit like cylinders and blocks don't seem to have any other use, yet.Keith S wrote: ↑Thu Apr 11, 2019 5:13 pm How I wish I lived nearby and could nip round for a visit to see this model being built.

It's honestly nice to see comments from people saying they enjoy the thread as sometimes i sit there and think, I wonder if anyone is actually reading this, let alone enjoying it, lol

Re: Another Wild Rose Project
No, he is 50 miles down the road and we only get over there about once or twice a month these days. Unfortunately his health is not the best and although i will take it over to show him he is not able to help me with it. I am hoping one day he can teach me how to make my own HSS tools for the lathe. All the work so far other than the few purchased items that he gave me have been entirely off my own back. He will get to see how it's progressing on Saturday when we go over for his local 16mm club meeting that way as the last time he saw it was when he gave it all to me in a tin about a month ago.tom_tom_go wrote: ↑Thu Apr 11, 2019 10:17 pm Hi Steve,

Re: Another Wild Rose Project
Thanks Rod, again I am sure you know what I mean though, it's very difficult to tell if there is any or much interest at the end of a computer screen as I read many many posts and really enjoy them, but I don't always have anything to say so no one would ever know I enjoyed it.
We could do with just a "thumbs up" or "like" per post, I am sure there was a forum that allowed that, maybe it was mad modders or something like that.

Re: Another Wild Rose Project
I don't really care if people view my threads Steve, has there is one member who is a pain in the backside to me. I won't go into details..
But on the viewing side of them, I do really care, because that's one of the ways I can learn from the very helpful replies from the far more experienced members on this brilliant forum, even if they are sometimes critical, thankfully they are few and far between.... But you can also learn just by viewing Steve and not having to say anything about them. I know that members do learn from one another just from viewing, because they will use your ideas in their own builds with some fantastic builds also.
keep on doing what your doing Steve, you do a great job and are an inspiration to me and other members too.

Re: Another Wild Rose Project
Go for it Keith! The majority of work is not on the lathe or mill. There are excellent books to learn about machining, like the Workshop series. A home built loco is much more rewarding than a bought one
Best wishes,

Re: Another Wild Rose Project
Well, my Dad bought me a book with some simple projects in it -one is the "Jenny Wren" little stationary steam engine. Might be a good thing to start with, but it's difficult to know HOW to start. I don't know anything about these tools. Someday I will take the leap though.

Re: Another Wild Rose Project
Thanks Ian, I appreciate the comments:)Oily Rag wrote: ↑Mon Apr 15, 2019 7:41 pm Hi Steve,
I think you are doing a grand job so don't worry too much. I have just really picked up on this thread and will follow with interest. Just one little thing. You mention the grubscrew drilling on one crank slipping off centre. I do hope I am not preaching to the converted, apologies if I am. Do you know of a tool called a Slocombe centre drill? Its usual usage is for making deep running centres on bar stock for turning between centres in the lathe. However it makes a great spotting drill when having to drill for things like grubscrews on a curved surface. The trick is to set your work up in a vice with the location of the potential hole uppermost.
Then place a 6" steel rule across it, bring the quill of the drilling machine down onto it, trapping the rule between your work and the Slocombe. First time it will not set parallel with the bed of the machine (unless oyu are a lot luckier than me) so just move the work gently under the point until when trapped the rule is parallel with the vice jaws/table of machine and at right angles to the quill. Slip rule out and then just spot about the size of a centre punch mark (enough to start your standard jobber drill) and then just drill with your normal drill. It won't slip down the curved surface and will generally be on a perpendicular radius to the curved surface.
I rarely centre punch even flat surfaces now. I usually set out my drillings with a Slocombe centre drill on the mill using the offsets of the mill table. I can then drill at leisure if you see what I mean.
It takes longer to say it than to do it.
I use Slocombe drills for starting centre holes in the tail stock on the lathe. I have those, spotting drills and jobber drills, however I confess I have no idea which I should use when or where as I am no engineer, not do I have access to an engineer to advise me on such things. I watch the odd youtube video and read the odd book and just work the rest out as I go along, in fact being totally honest, I had to Google what a Slocombe drill was to know I had some and use them as I had no idea of their proper name, as with most things unfortunately
Great advice on the how to drill on a radius without centre punching as I do now centre punch all my work before srilling, however, they either slipped a little or I centre punched them in the wrong place, not just the one, but I do this a number of times. I will confess I do need to wear my close up glasses when doing centre punches and trying to drill them afterwards and I will also admit I don't always have them on me so I forget and try to do it without them. I have only just started to wear glasses as I am getting older, so it's all a bit new to me. I will also confess I need more direct lighting under the drill and mill, I have an LED ring under the mill, but it's not all that and one segment has recently stopped working which doesn't help matters.
I have no idea what this means below? If you could elaborate that would be very helpful, however please remember I have no DRO on my mill on either the X or Y axis. (OK, I will also admit, I keep forgetting which one is the Y and which one is the X, I keep looking it up and keep forgetting, mainly because it doesn't seem to match how a lathe is done )

Re: Another Wild Rose Project
Just go for it, it's the only way, start small and work up, the first thing I ever made was a tail stock die holder and even that was too big to start with really, just find simple turning jobs, like diesel exhausts and tap them while they are in the lathe. It gets you used to machining to particular dimensions gives you something half useful afterwards. So many helpful people on here if you get stuckKeith S wrote: ↑Mon Apr 15, 2019 6:03 am Well, my Dad bought me a book with some simple projects in it -one is the "Jenny Wren" little stationary steam engine.
