Yes Drummond . Note the double bed.

Thread: Wooden Gears

Watermills and windmills used fruitwood such as apple for gear teeth, although this was running against cast iron. This website has a list of the properties of different timbers for making wooden clock gears, so it might be relevant.

I remember sometime in the late 60s our village blacksmith recall that many years previously he had repaired the watermill gear with inserts made from Holly. The individual teeth were trimmed to fit the rim . I guess the logic was that the frame of the big gear was made of timber with a bit of resilliance but the teeth were hard wearing and easy to replace. Other than that it sounds like this lad is going to build a nice little bonfire.

I use them all the time , never a problem. Imperial end mills etc get a quick measure with the digital calipers just to see theres no brain failure and away you go. I can't think of a good reason to buy both metric and imperial sets.

Is it actually a mill? Machines that small and that heavily built are usually jig boring machines. Just my tanners worth so pitch in whoever cares to contradict.

There have not be many Christmas Day roasts that have not had goose on the plate.🙂 There are two in the freezer at present. Fresh farm items are just too expensive these days.🙁 Much better than turkey, IMO.

You're spot on there, I note that you have 2 and that's good as the yield isn't great. Newbies will also note that you need oven space the size 2 breeze blocks just for the birds.

Ancient Rome was guarded by the Capitoline geese but it was more to do with the racket they made than ability to attack .

The walking stick advice is correct . Face the geese and swing it left to right repeatedly in long slow arcs at their head height or a bit lower. Geese know that their long necks are vulnerable to damage and will back off . I use this technique with swans when fishing , never fails. Even a long stalk of grass or reed will have them on the run.

Pellets work well , the best ones are made by Webley and Scott who also provide a suitable applicator.

Finaly some professional advice from my ch-effing days. Apple sauce , roast spuds and peas.

Thread: Message from ARC to our customers in the E.U.
10/12/2020 11:13:40

So you import direct bypassing the retailers in the UK , dodge some tax and avoid the retailers profit margin. Lovely ! If you don't support the likes of ARC, Warco etc they will disappear . Which of you will be the first to start crying like a baby bird at feeding time because your local school or hospital has been shut down through lack of funds? Who will post an epic tale about a lathe that arrived broken and you can't get your money back? Finally someone winging about how it's a disgrace that China owns us lock stock and barrel. Use some grey cells ,please.

Thread: Drilling addition holes for gib screws has caused distortions in the slide
13/11/2020 08:19:57

Something that I've mentioned before in the context of bed warping is that cast iron behaves very like chipboard . Tight hole close to an edge , in goes a screw , result bulge on the edge.

Thread: Newbie with no prior skills on lathe

Welcome . A good set of ready to go HSS tools is your starting point , not too many , a set of 4 of 6 will get you started and beyond. If your learning you'll just find a world of pain with insert tools . Not that the Drummond cant handle them if used appropriatly just that it's task up from the basics. The lathes.co.uk site also has some general basic how to pages , well worth a read. Have a look at the Drummond Myford group on FB friendly bunch and a wealth of Drummond knowledge.

Thread: Lathe Tool Grinding
03/11/2020 08:20:01

Grinding your own is well worth the time and effort required. A usefull project is to fit a very stable rest on to your bench grinder. Make it larger than the old floppy one and possibly build in a guide system. It doesn't have to be a masterpiece , just functional. One other point, several posters have quoted angles of ''about x degrees'', absolutley right , you don't need to get into 17 1/2 degrees or whatever just get it about there.

Thread: Why is this guys mini lathe parting off so well?
23/10/2020 11:06:54

My Drummond Admiralty B type is not the most rigid machine so I avoid insert tooling and anything else that might upset it. However it's party trick is a Glanze parting insert tool and powered crossfeed . Consistent feed and a free hand to keep the cutting oil flowing does the trick.

The only slight thing that is wrong with your last post Lee is the word "disputed". The bolts are nipped up and left alone, indisputable.

Not disputed by me , I'm just refering to the run of the thread and a video.

It's a cracking little chuck and I have a small aluminium piston to make for a Walther LP3 target pistol , Just the sort of light work it was made for, very pleased with it.

I have read this complete thread over twice now. Conclusion right or wrong is.

There are 2 types of this chuck. The main one is a chuck mounted to a back plate by long screws from the front face of the chuck approx 2" long. These go through clearanced holes the full thickness of the chuck to threaded holes in the mounting plate. The Myford one which i have has a dedicated backplate & is bolted directly to the rear of the chuck by means of threaded holes flush with the rear of the chuck.

I think logically that the front entry bolted type would be much easier to adjust without any slackening of the said bolts. C on the diagram further up this thread.

On the Myford type i can see why it would be much harder to push the chuck sideways when boited directly with short bolts , straight into a threaded entry. No flex The front mounted type has around 1 5/8" of free shank to be able to deflect.

Waiting for the gunfire.

Steve.

Mine has the adjustable backplate , this then has an adaptor backplate secured from the rear so that it covers up the disputed loosen or not bolts , so it is clear that they are not intended to be loosened.

I have it on a non running lathe now and I have it to a half thou. The bolts have been taken up to a light torque on the short side of a normal allen key. This light touch is a bit counter intuative untill you remember that it is the adjustment cones that are keeping things together.

As for the adjustment procedure it's easy once you get the routine in your head. Loosen opposite before you tighten and numbers on the chuck help too.

20/10/2020 16:37:22

It's back together on the bench. I previously mentioned that it was choked with swarf there was even some in the bottom of the backplate retaining bolt holes. That leads me to concur with SOD Dave on the points he makes.

I'm now at the trial and error stage with the torque. I should add that mine is mounted on the adaptor plate mentioned in the PB instructions and no slackening or adjustment is possible once it's mounted on the lathe.

No 3 jaw is a mighty clamping tool (some seem to think they are  and this one I see as a light duty chuck with the benefit of being able to clock it in like a 4 jaw for every job.

20/10/2020 08:06:30

Perfect timing , I have one on the bench right now that came with an ETA lathe aquired earlier this year. Never seen so much swarf in a chuck before , preventing that is something I will address on reassembly.

I'm seeing 2 points in the previous posts and the PB instructions that are as I see it key to getting the desired result.

1. The correct fitting to the backplate is vital , Blindingly obvious ? No , not if you have no idea how the job was done in the first place so I'll give it a thorough once (or twice) over.

2. Damage is done to these chucks when adjusting if the first step in the sequence , slacken off all the adjusters , is ignored.

Finally. The idea is to take up a few thou not half a yard like a 4 jaw. There should be no need to slacken the retaining bolts.

I'll be back later to eat some humble pie when all my theories are blown out of the water.

Thread: Optimum products?
18/10/2020 21:43:16

I have a large bench pillar drill from Optimum. Can't fault it and I did look at a lot of the other offerings available elsewhere before choosing it. Too many that I looked at had a quill that waved about like twig in the wind , the Optimum is solid.

I have been involved in work on a few historic aircraft but one of the most bizarre was a military aircraft namely the Canberra.

The company I worked for did a lot of work on service aircraft and we were asked to make a new throttle box for one of the PR Canberra's that were then in service. Most of the work was quite straightforward, until, that is, the provision of the rubber covering for the throttle levers.

These had been made by Raleigh in Nottingham and were the handlebar covers for a children's bicycle made in 1946 or thereabouts. Needless to say, they didn't have any spares!

I'm not sure how we worked around that one, probably by 'phoning every bike shop and restorer until we found some that were useable.

Brian

That reminds me of the HP 115 , a one off slender delta research aircraft that was part of the Concord development . A last minute panic for a brake lever produced a Ford Popular hand brake from the dealer in Radlett.

The fuel guage on my Father's home built Turbulent was 2 ping pong balls and some welding rod.

Aircraft grade aluminium ? Not much different from 6082 T6 architectural grade that's easily available , it's the availability of thin guage sheet and tube that drives towards aircraft spec........... And then theres the paperwork to prove that it realy is what it says on the tin £££
