|Thread: drillling bronze|
Would anyone volunteer to put up a picture of the drill bit that's been modified as I to need to drill through some stays on my Minnie traction engine build, I have already broken 2 drills and have had to have them spark eroded out already and don't fancy repeating
|Thread: CovMac Lathes|
Where do we find your clip of your covmac lathe in action?
|Thread: Minnie traction engine build|
I've found my book now SWMBO has had a tidy up
I have the strakes and spokes made I was just wondering about the rivets,
This is a long term project and my first real build I'm going to take my time, I have a good group of very knowledgeable friends in my local engineering group, which are offering a lot of advise so between them and advise on here I'm sure I'll get there.
Theirs a few things which are confusing me when I start to make the wheels are the (spokes) riveted or screwed into place the same question for the wheel strakes if they are riveted too ? if so are these homemade or can you purchase them and what size?
I had a set back I managed to break 2 drill bits while drilling the stays, I have found a firm that has spark erosion which has now been done. In the mean time I have cut out the horn plates ready.
|Thread: What lathes have you had?|
I started with a lathe called the IDEAL which my dad taught me on 30 years ago I still have it and have restored it, I don't really use it but can't bring myself to part with now he's not around anymore.
Then a RELMAC another basic lathe and a rescue project from a local farmer that was going to scrape it it served its purpose at the time.I then upgraded to a Atlas ( sphere ), one of the worst things and the biggest mistake I ever brought, I'd been told it was a okay lathe but when I got it it had been parted out and was a bag of nails
I am now proudly own and use daily a Raglan little John Mk2 with a QCGB I would never change my lathe for love nor money, unless it was for another raglan little John mk2 it may be old (1954) but in (my own opinion) one of the best lathes ever and punches well above its weight for its size.
|Thread: new toy and my latest engine|
I have one of those milling machine their fairly good, I've tried looking for information on the net for it but there isn't much? If you need to know anything I'll try and help just send me a pm
|Thread: Minnie traction engine build|
I'm starting on my first ever proper build so please be patient if I have any silly questions. I've owned my lathe a little John mk2 for about 3 or 4 years now, a part from doing odd jobs etc I haven't really built anything like this before, so I'm looking forward to this adventure.
I have brought the casting and all the instructions/Manuel and plans, book and everything I need for the build a "Minnie traction engine", the boiler has already been made and has a test certificate for it but I've stumbled at the first hurdle I've been trying to figure out how to fit the horn plates to it would anyone have any suggestions? (Please look in my album) Is it okay to drill through the stays and tap them so they can be bolted on?
|Thread: Horizontal mill cutter|
Thank you for all your help I've learnt a lot today. I had a very interesting conversation with RobCox earlier this evening, I gave him the information of my 3 phase converter which he has told be is to small for my mill and that's the reason it's tripping all the time, hopefully by changing my motor to my spare 1hp motor and getting a larger 3phase converter will hopefully solve 1 of issues I have. The other having the cutters sharpened he is also able to help with too so a big thank you to Rob for all your help and advise and everyone else's input too. Once I have everything changed I let you know how it's running
The majority of the cutters I have a 2 1/2 to 3 inch diameter and 1/4 inch ish , apart from one which is 1" thick which I couldn't use I couldn't imagine using a slab cutter on my mill? I've put someone pictures in my album of almost all my cutters I have and tried.
Thank you for the continued help
I'm looking for some words of wisdom from forum members please, I have a Ajax aj8 horizontal milling machine which I've not had for very long, I have a few issues with it I'm trying to sort out, a friend gave me several cutters to get me going, I think the cutters are blunt/dulled and I would like to have them sharpened would anyone know where I could get them sharpened at a sensible price? or would a kind member here be able to help sharpen them for me for a donation
The other issue I have is when I got the mill is it didn't have a electric motor with it so ive fitted a 1/2 hp 3phase motor and converter I had in my workshop, the motor spindle has a 1" pulley on it going to the 7" spindle/arbor pulley. I've been trying to cut a 20mm slot in BMS 50×50 square bar to make myself some qctp's for my lathe, (the first one took me about a week to do between work and family commitments) what I'm finding is either the cutters won't cut or if I take a cut deeper than 3 to 5 tho it trips the 3 phase converter, I have 2 identical converters and have tried both with the same result (tripping out) the cutters I'm using are HHS 2mm width up to 1/2" I haven't had any problems with slitting saws. Would I need a bigger motor like 1 hp or would this be to big for my mill?
Any help and advice would be appreciated
|Thread: What is this?|
I was given one identical to that one with all the parts for it, I haven't got around to making it yet. I have some plans for it I'll try and find them out for you

|Thread: What lathe is this ? Grimshaw|
My neighbour has just found his great Grandad's lathe and would like to know if I can do it up /clean it up?
Would anyone know about these little lathes? The only name on it is GRIMSHAW and it's made of brass I've looked on the interweb but couldn't find much information so I'm putting it to the collective
I've put some pictures in my album as I'm not sure how to put them in the post here. Any help would be greatly appreciated
Many thanks in advance
|Thread: Hole cutter|
|Hi there |
From one raglan LJ mk2 owner to another I know I'd have to take a seriously deep cut before my 1/2hp single phase motor would start to labour and I've never stall it, I'd check your motor first sounds like you might have an issue? these lathes are very powerful for their size
|Thread: Lathe identification|
It could be a Halifax,Sears,all copies of the atlas lathe. I used to own one a few years ago very nice lathes to operate. Your looks like you have a few items missing tho?
|Thread: Holding work on the cross slide|
|Hi Robin, |
When I did my first basic Line boring on a lathe I managed to clamp a angle plate to the cross slide T slot and then clamp the work to the angle plate running a homemade boring bar between chuck and tail stock. Would this be an option for you? I did put a short clip on you tube
