Wow, I guess your planning on a trailer of some description.

Yep, haven't decided yet whether to get a simple open trailer or a posh enclosed one. Of course it's not just the engine you need room for. There's the driving trolley, coal, water, tools and the wherewithal to make simple repairs. Mind you I'm a way away from needing to make a decision.

Andrew

Andrew, you know what the perfect vehicle would be..? a van based horse box. It wouldnt need to be a big one, say transit size. The long wheel base ones have a small living/sleeping area behind the front seats, plus you get plenty of space in the back and even a fold down ramp for driving the engine in and out, perfect.

Thread: Mini-Lathe Repair

Thanks guys,

Jason, thats the worry I have with metal gears, thinking about it, although its a pain having to strip down to remove the head its really not such a big deal. This is the first time I,ve done it and its not difficult, as Bill says it is probably a couple of hours work especially after you have done it the once.

Thanks guys,

I am starting to wonder if changing to the metal gear set would be a better option, they are said to be noisy compared to the plastic but if they provide a more reliable drive I could live with that. I have only hesitated in considering the metal gears as the plastic ones are thought to be a safety valve/fuse which avoids damage elsewhere.

About a month ago I stalled the lathe twice whilst parting of some steel, it survived the first time but I lost the low speed range on the second time. I knew the high/low range gears in the head are plastic (nylon) and it seemed pretty obvious that a gear had stripped. The high range was still ok so I have been using the lathe since.

I finally bit the bullet and stripped it down to remove the head and as you can see in the picture the small gear is well and truly stripped, it is also split. The gears are one thing and easily replaced but what annoyed me more is that the inside of the head is bone dry. There is not a single smear of grease or a drop of oil anywhere, it was assembled in the factory with no thought to adding any lubrication. I know some argue that the nylon gears dont need any lubrication so maybe thats what the factory work to but you would have thought they would lube the gear change assembly and its operating lever.

I checked the rest of the drive and parts for damage but it all seems ok.

Strange how everyone says carbide tips don't like interrupted cuts on the lathe but there are plenty of tipped fly and milling cutters about that do that every day..........

Paul.

I"ve often wondered about that.

Bazyle Hopper and Paul - thanks for your help - am off to the shed to see what I can do.

Bill

I wondered about that too but in making my flycutter I used the boring head with a carbide tipped tool (side mounted) to flycut the 20 degree angle on the head of the cutter. It was a brazed tip tool though not an insert tool and it worked absolutely fine, in fact it made me wonder as to why I,m making a flycutter as the boring head with a suitable cutter works a treat. However I would rather not use the boring head for fly cutting and keep it for its intended use.

Picture below of the boring head with a modified carbide tipped lathe tool, as mentioned it works and cuts really well but it is only a stand in until I finish the flycutter.

I also got some time today on the flycutter I am making, despite having a sick lathe at the moment I did manage to turn the body. I then gave a bit of thought to the best way to produce the 20 degree angle for the tool mount. I was going to go with a 10mm end mill (the largest I have) but thought that across 40mm diameter that would be a lot of back and forth with each cut.

So I decided to flycut it using the boring head, I set it up at 20 degrees in the vice and took 0.5mm cuts. It worked a treat and the bonus was that each pass of the cutter covered the full diameter. I dont know how they are normally set up and cut but that was my take on it.

I do like the Fowler modelled in a military finish, I think that looks really excellent.

Interesting how the gun has traction engine type wheels, I guess in those days if large wheels were needed for heavy equipment that was the way to go.

Thats its Jason you dont miss much, yes thinking about it, it is the tool I used on the hornplates which were sandwiched together and the width of the band fits.

05/12/2018 07:31:29

I,m guessing that the band on the side of the plate is telling me that a section of the end mill has lost its edge..?

Hi Vic,

I did consider that but the main reason for the plate is to increase size from 4 inch to 6 inch diameter I will probably add holes as jobs require but starting off with Tee slots I thought a good idea.

Ron,

I wouldn't dress the sides, only the periphery although I am sure others will tell you differently! Strictly speaking you shouldn't use the sides of the wheel anyway (although I often do for a light truing skim on a tool bit!). For dressing it's less stress for the wheels and the operator to use a single point diamond dresser rather than the Huntingdon type with star wheels. Either make a mess though so cover your machines and have a vacuum cleaner sucking up the dust as you go, you don't want abrasive all over the slides of your machines! Diamond dresser should be relatively cheap, it's a stone set in the end of a length of steel rod about 5/8" diameter as a handle. Can't remember where I got mine, was years ago but I don't remember it breaking the bank, maybe £15 - £20 these days? You can get a pretty good surface to the wheel by gently sliding the dresser across the rest, you can use your finger against the back of the rest as a guide, be careful though especially if there is a gap between the underside of the rest and the guard!

Remember to make sure you have 'paper' washers between the stones and the clamping washers on the spindles and don't horse them up to some horrendous torque!

Paul.

Sorry Paul, I am a bit late in thanking you for the above advice.

04/12/2018 17:18:13

I,ve mounted the plate to the rotary table and although I had flycut both faces of the plate on the mill table I decided to cut it again once I had it mounted to the rotary. I used the boring head with the carbide tipped lathe tool I had modified, it really does cut nicely. I can just about feel the join between the two sides of cutting but checking it with a good straight edge there is no evidence of a step and I doubt I would get it any better.

So I have the four T slots to cut and radius the corners, had I been able to fit the plate to the lathe (too big) I would probably have turned it to 6 inch diameter. Apart from the look of the plate I cant see the need for it to be circular so I will machine a good radius on the corners and leave the sides in between square.

Its all model engineering Mal plus its good to see subjects that are a bit different, go for it.

Thread: What did you do Today 2018
03/12/2018 21:07:05

Today I put the 6" x 6" x 3/4" 6082 blank up on the mill and flycut both faces, this is for the adaptor plate I am making for the small rotary table and it is too big to put it up on the mini-lathe. Pleased with how it turned out, managed to get a really good surface finish.

I have also decided to bite the bullet and order the high/low range replacement gears for the lathe and get it fixed. I have lost the low range since I stalled the lathe parting off. I still havnt made up my mind whether to go for the nylon gears or the steel. The nylon gears are quieter plus some say they provide something of a safety valve against any damage happening further down the line. Of course the metal gears are far stronger but said to be noisy and could cause damage else where should the lathe stall or jam up.

I am making a flycutter at the moment and only having high range on the lathe is a real pain, I have to get 40mm down 16mm and the high range and a HSS tool only let me take really shallow cuts which would take forever. So I have changed to a carbide insert tool and wound the speed up to get the lathe more into its power band and that has helped, will continue tomorrow.

Have you started on the Bipolar motor Jason or saving it for the future.

Thread: Interests other than Model Engineering
03/12/2018 17:34:48

Just out of interest and if you are prepared to say..lol What 3 main interests do you have other than model engineering. You dont have to go into a lot of detail but I guess some of the answers could be quite surprising.

I will kick it off.

N gauge model railway: I have a scratch built layout (not finished) and apart from the track and loco,s most of it I have modelled myself.

Cooking: I just love cooking, no particular style of cooking but I do like trying to dream up recipes.

Ancient Egypt: Pyramids etc, dont quite know why but it has fascinated me ever since I can remember..

Thread: The demise of the High Street
03/12/2018 14:41:58

I think its pretty much the same everywhere now, I actually had to go into town (Barnstaple - North Devon) this morning. I had to kill an hour waiting for the wife as she had an appointment so I had a good wander around, first time in about 3 years. I couldnt believe the number of charity shops and coffee shops, they seemed to be every other shop down the high street There was also a good number of empty shops large and small

Barnstaple has an old pannier market and there is a small narrow street next to it which is known as Butchers Row. Its aptly named as it used to be full of butchers shops, there was 7 or 8 butchers, a couple of fishmongers and a bakery. There is now one fishmonger, a bakers but not one butcher they have all gone.

The parking cost in Barnstaple is quite reasonable but having had a good scout round today there is just nothing makes me want to go there. The few specialist shops it once had are all long gone.

Thread: scam?
03/12/2018 10:36:01

Last month I checked my online bank card statement and found an Aer Lingus transaction for £807.00 which was nothing to do with me.surprise I phoned my bank and they put me straight through to their fraud department who immediately cancelled my card. Two days later I received a form which I had to complete, sign and send back and then after another three days I received a new card and my account was credited for the £807.

I dont know to this day how someone got my card details and the Aer Lingus amount was the only one, there has been nothing against my new card since. I do often wonder how safe using your card online is, well I,m assuming thats how they got it..? quite scary really.

Ron

p.s. Forgot to say the payment to Aer Lingus was made in a travel agents in Ireland..?
