Thread: Elliot 10m shaper weight
17/09/2014 21:32:04

Thanks for the replies everyone. The weight is roughly what i was expecting, not too heavy but as some have said they are top heavy. I don't have the machine yet, but want to buy one, even though i know they are obsolete really. But as a machine they have always interested me.

Would anyone know the accurate weight for an elliot 10m shaper ? I have checked lathes.co.uk but cannot see one.

Thread: Wimshurst machine
13/09/2014 23:57:20

Sorry to resurrect this year old thread, but i just wanted to know how the build went gordon ? I too want to build a wimshurst machine, but all i can find online is rubbish made from bits of plastic and cardboard. One made in the classic brass and hardwood would be a nice ornament.

Ronan,

Check the publication date of the document in the link I posted.

Well i'll be jiggered, i always thought it went in the 50's.

I thought the broadarrow and war office were very old terms, and would have been long gone again the 70's ?

Thread: Hardness of gun bolt
31/08/2014 20:07:09

Hi Richard

Yes, he already has a similar gun with the mod made. Having looked at the price of solid Carbide cutters, I was thinking grinding might be better. The bolt certainly isn't case hardened, but it is hard.

I priced carbide milling cutters in the local suppliers (a branch of cromwell) and in certain sizes they were cheaper than hss, both the same manufacturer (sherwood).

31/08/2014 15:15:45

Gun actions are recommended to be around 30 hrc minimum and can go up to the mid 40's for 416 stainless steel actions. Whatever the hardness of the action, the bolt is always slightly harder to prevent pick-up and galling. All that been said, i was told recently that some ruger actions are up to 50 hrc in hardness. Its very difficult to tell how hard a metal is until you try to cut it , its been tested,or you've been told exactly how hard the metal is by a supplier.

Are these led fluorescent tubes a straight replacement or is there something else that has to be done to get them to work ? Can the bothersome starters be done away with ?

Thread: Restoring an Elliot Progress Drill

My machine is identical to Graham's apart from being the floor standing version which weighs even more. Neither Graham's nor mine have the gearbox, only the 5 speed belt drive.

Used to have a 3-phase motor and VFD on mine until I swapped it for a Christmas cracker quality Chinese 1-phase motor so I could liberate the VFD for my milling machine. It's less useful in this state but its reduced usage is more down to the fact that the milling machine is more versatile for drilling anyway and more accessible. Nice machine though.

The conical recess under the head almost cries out to house a lamp and seems to be designed for it although it doesn't seem to be used for that purpose. I wonder if that was the original intention.

Murray

Yes murry i believe the recess was intended for a worklamp of some type. I was going to use a vfd with the original 3/4 hp hoover motor on my drill, but it wasn't a dual voltage unit and as such couldn't be run from a vfd as easily (or cheaply). As i had gotten the drill for free anyway i didn't mind spending out for a new motor. The only motor i could find for it locally was in the engineers suppliers and bearing factors. It was an australian made 1hp motor and it fitted the machine with no problems at all and has all the power i'll ever need.

As for the weight of the drills, i seen somewhere the bench model is supposed to be around 2 1/2 hundredweight, having had to lift my drill onto a bench i think that would be an accurate weight. Finally gate machinery still hold the progress name and stock drills called progress, though i'd imagine they are rebadged far eastern models. But they did hold some spares, but not a huge amount i'd think.

I have an identical drill oompa loompa. Mine came out of a scrap skip, wrestled out by a friend of mine in his lunch hour. They are a proper professional grade tool and light years ahead of the taiwanese and chinese junk. All i did with mine was replace the three phase motor with a 1 hp single phase unit and gave it a quick lick of paint to stop it rusting.

I might rebuild it over the winter as its starting to jump out of high gear under load (caused by idiots not stopping the machine before changing gears) . There is an excellent thread on an elliot drill rebuild over on the mig welding forum (its not you is it ?).

Thread: Preserving a lathe for long-term storage?
29/08/2014 18:54:34

We used to use a shell product called ensis fluid in my old job when we wanted to store large machined rollers outside. Its supposed to be good for protecting metal stored inside for 60 months or outside for 24 months. Its commonly used on oilrigs for protection of bare metals , or so i am told.

Thread: 3 phase motor running from single phase supply
06/08/2014 22:07:37

Someone told me to try this idea of using capacitors across the lives to get a small coolant pump motor running on a colchester lathe. I didn't do it but apparently it works ok for small motors.

Thread: mig or tig
07/07/2014 01:31:50

Some of the chinese plants, r-tech for instance have siemen electronic components, not something made in a sweat shop in a back lane in the back of beyond. Something else to know is a lot of the american welding plants with some prestigious names are made in china or italy, and only assembled in america.

06/07/2014 20:00:58

Pure aluminium is actually pretty easy to weld, its when the metal has old oil or grease absorbed into the pores of the metal , or when the ali contains zinc or something it gets messy and frustrating. Believe me ,i used to work in a fabricators/welding shop where all sorts of work was brought in. To be asked to weld something in new clean ali was a welcome relief.

06/07/2014 10:28:17

A really good welding set that can be had for reasonable cost is the chinese made r-tech. Don't let the chinese put you off, these are very good machines and the uk agent has a no quibble warranty where if something goes wrong (never anything major i hear) then he will put it right. Also you do really need ac for aluminium, you can use pulsed dc but with ac and the correct gas you can get lovely clean "stack of pennies" type welds.

Have a look on the mig welding uk forum and also doubleboosts channel on youtube.

Thread: Using Riffler Files - HOW>
20/06/2014 13:34:12

Quality files of any size are expensive now ian. I bought a pack of 16 files for €30 during the week when they were on special offer in a local engineers suppliers, they are good enough for deburring etc, but nowhere near as good as the old stubbs or nicholson files.

Thread: Wooruff cutter speed
16/06/2014 12:36:51

Thank you thor.

15/06/2014 21:52:59

Are woodruff cutters generally run at slower speeds than endmills of a similar size ? I have rarely used these cutters and when i did it was a long time ago.

Thread: Carbonfibre Push Rods - Good Idea?
15/06/2014 18:31:03

I looked into pushrods a lot as i am into classic british cafe racers of the 50's and 60's. There are a lot of parts suppliers catering for the classic racers. There have been pushrods made of all sorts of materials, carbon fibre, aluminium alloys of various types, titanium alloys, but for the best combination of strength and lightness most settle for thin wall high carbon steel tube with end caps fitted.

Thread: WD40 alternative - any good?
13/06/2014 21:41:50

The only time i use it is if aldi or lidl have it cheap, no way would i pay full whack for it as imho it is overhyped. To preserve machinery during the winter i buy a litre of cheap super market oil and apply it with a rag or brush.
