Thread: Building the Stent Tool and Cutter Grinder
25/06/2019 16:42:15

Hi

My thanks to IanT, Thor and JohnF for their offers of help. I now have all the articles I was looking for. I’ve spent this afternoon, reading through the articles in preparation for the build. The castings etc I have are part machined, and it look like the work already done is to a high standard. I now need to understand the modifications that have been done to the original design and if I should/could incorporate them

I think my next job is to document the tooling that came with a Clarkson T+C grinder, I purchased 6 years ago with the intention of getting it up and running. It’s stayed in the corner since, and now I have this project, I think it is time to release both the money and the space.

Thank you to all the offers of help

Hi

Is anybody able to help me with getting copies of the Model engineer article series on “Building the Stent Tool and Cutter Grinder” ? The Online archive doesn’t go back far enough. The table below confirms which year and volume the articles appeared in.

If you are able to help please private message me. I’d be happy to pay any reasonable costs for copying and posting.

Thanks

Tony

Re: machining experience (zero)... some thoughts

The SMEE run courses on “Basic Training for Model Engineers” , “Lathe Tool Grinding” and “Milling”. I’ve done the lathe tool grinding and milling courses both of which I found useful in raising my knowledge base

The SMEE run a Building a Simple Steam Engine (“The Polly Course). I haven’t done this one, but those that have give it a ”thumbs up” .

The bad news is that the Polly Course only runs one a year and has already started

Thread: Precision Level or Precision Frame Level
03/05/2019 15:09:52

Hi JB

I’ve just spent the last week sorting out my Harrison T300 lathe...I tried using the Rollie Dads method but found the accumulation of errors (taper adaptor, test bar etc) difficult to resolve, so went for levelling the lathe. Having levelled the lathe, I did a test piece and had an error of 1/1000” over about 6”. Tweaking the relevant lathe foot, now gives me no error over 6”

If you would like a recommendation: the level I used was a Moore And Wright Machinists Spirit Level. 12”/300mm. I found it perfect for the job required. My level was second hand, from the well known auction site. I’ve just checked and there is one currently available (buy it now £79.99)

Hope this helps

Hi BugBear

Googling brings up

24mm long “Metal Shelf Support PEGS Stud PIN PEG Kitchen Cabinet 5MM Hole” (Amazon)

https://images-na.ssl-images-amazon.com/images/I/81a9LxOPsbL._SL1500_.jpg

At £2.63 including delivery would it e worth a punt to see if they are what you are looking for?

Hi David

I would another reference book along side “Screw cutting in the lathe” . For Christmas, I was given “The Gearing of lathes for Screwcutting “ (Crowood Metalworking Guides). It has two chapters “The Myford ML7 and Variants” and “The Myford ML7 with the David Machin Gearbox”. It has lots of detail and, in my opinion well worth the purchase price

Hi Rod and John

The problem might be the different expansion rates of the metal to the insulation. Try SikaFlex 512, which is the product used for mounting solar panels on campers/mobile homes...to quote the manufacturer "Sikaflex 512 is a flexible adhesive to allow different materials to expand and contract at different rates"

Most importantly make sure that both surfaces are abraded and cleaned. Sikaflex instructions say 3mm bed minimum.

Just one note of caution! Its good stuff, once its set you will need to chisel it off to remove it

Thread: What depth concrete base for a workshop extension?
16/07/2018 14:48:09

My thoughts!

Install a damp proof membrane under the slab

Minimum of 100mm/4”

Check out and agree the mix ratios prior to work being done. In my case what went in was a bit weak on the cement, which resulted in a dusty top layer

Thread: Help with silver soldering (Yorkshire area)
18/03/2018 21:04:52

Hi Keith

Thanks for the prompt, I'll look into it next week. I'm hoping to attend the CuP Alloys on the Road 2018 Club night at Grimsby, on the 17th April. Hopefully I'll be able to say hello there?

Hi Fizzy

Thanks for the offer, I've sent you a private message

Hi

I’m hoping that somebody with brazing equipment is willing to help me! The door handle (see photos) is from a 1920’s building and suffered some metal fatigue. I’ve made a repair, which just needs silver soldering into the door handle boss. I’ve tried today with my “plumbers” blow torch, but I can’t get it hot enough to melt the silver solder. Is there somebody in the Yorkshire area (I live in Leeds) who has the correct kit and is willing to help me? The silver solder I’m using (CuP Alloys 455), has a melting point of 630C - 660C

Thanking in anticipation  Tony

The restoration tonight is on The Sierra #3 >> “The Sierra #3 steam locomotive was built in 1891, by Rogers Locomotive Works in Paterson, New Jersey, and is one of the few locomotives from this era, still in operation”. Think "Back to the Future III . The programme is repeated tomorrow (3rd Jan at 12:55 and 17:30)

Thread: Removing mt0 centre?
05/10/2017 14:14:56

Hi Bugbear

Is it possible to take the tail stock off, and upend it to allow a “drip –drip” of easing oil down the barrel, leaving it overnight, perhaps longer?

Warming the whole thing in an oven before starting may also help by expanding the metal sufficiently to allow the easing oil to track down

Don’t be impatient and apply force too early! If para 1 and para 2 fail, go back to para 1 and try again

Hi Nige

Do a search in Youtube on

"lathe headstock alignment"

"lathe tailstock alignment"

for some visual demonstrations on the techniques for checking alignment

Thread: Armoured cable - what size would you reccomend
20/03/2017 18:19:36

its likely that volt drop will be the deciding factor, rather than current rating. There are a number of volt drop calculators on the www. I’ve found this one.

**LINK**

Assuming 10 kW load, and 30 metres, assuming 240 volts incoming at the meter position, it recommends 6 mm cable, for a 10Volt drop . For 6 kW the cable size can be reduced to 4mm.

To check your typical load, look at the rating of the motors on your lathe and milling machine, and pick the largest . Just a note of caution, the larger the volt drop, the bigger the “dip on the lights” when the motor starts, which can be annoying.

My recommendation would be to go for a minimum of 6mm, especially if you are digging a trench to bury it underground

Thread: Tom senior bellows/way cover
12/02/2017 11:33:37

Hi Ronan

I suffered the same problem! I had some rubber gasket material which I cut oversize and fixed using some aluminium angle. The fixing holes in the Tom Senior were already there. I've always intended cutting most of the angle off, just leaving enough to stiffen the fixing, but have never got round to it.
