Thread: Machine Tool Peripheral Hoists
02/06/2020 09:36:15

Clive - Thank you again for the 'mental nudge' re. counter-balance mounting. I have just the sort of thing you describe - ex commercial, foldable metal trolley on casters, covered with 'come-in-handy' items of considerable weight. Managed to 'clear a 7" x 7" space in the top shelf corner and the swivel boom swings to stay within the trolley outline. Sorted!

Once I get it bolted down, I'll take a piccie.

Thank you Clive.

Your suggestion re. the rolling cart is a 'bulleye'! Even I ought to be able to rig up something suitable. The obvious potential 'gotcha' is the counterbalancing but I shall consider ... and, no doubt, procrastinate!

Just noticed this thread.

The photos below show a bodge modification I made to an ex-car hoist for mobility scooters.I had to do a bit of rewiring and incorporating a transformer power supply (RS variable output). The base is 7" x 7" x 1/4" steel with corner holes for attachment. Original s.w.l. was, apparently, 160kgs (?) so probably OK for chucks etc. Not sure if I'll get round to installing it.





Thread: Aircraft General Discussion
30/05/2020 09:55:08

V8 - interesting concept ... but ...

Rather too many battery-related aircraft incidents for unlimited confidence at the moment. Batteries are only an intermediate in the 'power train' ... the charge source (coal, nuclear, gas) really needs to be hydrogen to have any realistic value in climate change.

The discharge curve would make interesting viewing.



30/05/2020 09:41:45

Thank you , Neil - so that's what Horace said! yes



Thread: Repair advice, please!
28/05/2020 11:55:57

Adrian, thank you. In fact, I have such a tube - ex Shoprite(?? radial arm saw - the source of the patch shown in photo 2.

Keith, thank you also and your suggested source is noted - sounds possible. I don't have enough engineering knowledge to visualise the 'proper split cotter system' - could you expand a bit, please?



28/05/2020 09:41:33

Jon, Pete, John and Nick thank you. Your caveats re adhesives have been taken on board and that option moved to the bottom of the list. Nick., I have a set of original drawings, so could work from those.

John R - sounds like a possible option but I would see the need for some serious heat producers - e.g.Sievert or Rothenberger rather than my camping gas jobby.

Any way thank you all again - excellent brain food and I 'll let you know what results. It might even be a return to the present Zero Clips arrangement!

"Zero Clips"?? ... the black ridged item on the left hand end of photo 1. It is one of several (for me) 'must have' workshop items - a bodgers 'go-to'. The black ridged item is the basis for a plastic 'Jubilee Clip' which has a similar material securing collar producing an extraordinarily high clamping force. They can be joined to produce any length needed and I have (confidently) used them in the past as life-line type supports. The one in the photo has been used as a stop-gap clamp across the cracked area and has withstood all imposed loads, so far. The search for repair methods is to do away with such an obvious 'bodge!

Yet again, many thanks for useful comments and ideas but very particularly for Pete's most generous offer. The extraordinary open-hand towards a total stranger is very special. I think the logistics would probably defeat me but, if you're ever in the North Norfolk coast area, there are several 'thank-you beers' in the 'fridge!

Again, food for thought, including a reply from Araldite suggesting a guarded ' would probably work, with careful preparation and the metal strengthening plate'.The 'metal stitching' would almost certainly be the most reliable but the process is (unsurprisingly) an 'inhouse' affair -i.e. not diy and undoubtedly expensive.

Kettrinboy's experience and the proven results sound extremely encouraging. I would be more than happy with that quality of finish although mine more likely to be much less elegant. Your short account of the process was much appreciated - any further hints and tips would be very welcome.

pgk - good point made adding to the 'ching, ching, ching' factor!!



27/05/2020 12:23:56

Thank you all again, chaps. Some very interesting suggestions tempered by personal competence and age! Just had a look at robjon's suggestion - very impressive looking technique!

Howard's idea, particularly as modified by pgk, could be a 'goer' -certainly food for thought.



27/05/2020 09:07:01

Thank you Pete. If I thought that I could produce a result half as good as that I would be a very happy bunny - sadly, I see it as very unlikely. Still waiting for a reply from Araldite but I get the sense that the adhesive companies (for obvious reasons) will be more concerned with commercial enquiries.



26/05/2020 09:37:08

Thank you again, Adrian. That link is quite interesting and the D-W head/motor support shown is definitely intended for serious work!! Unfortunately, I have an 'Eliza's bucket' situation!! sad Even if I had the skills (very doubtful) to manufacture the item, my machine to make it is the one requiring repair!!

I note, however, on a different, current thread, discussion on the merits of Devcon/JB weld etc. which would have considerable personal appeal and which I had seen, initially, as strong (pun intended) contenders. There has been no enthusiasm on the forum, in that direction, so far.

I have emailed Araldite's website for their view on such application and await their reply.



25/05/2020 16:54:00

Thank you very much gentlemen - all good advice and food for thought.

Nick C3 - I believe they are out of production (used to be Hemmingway kits)

Was I the only one who noticed that its a Victor 1a?

I know you lot aren't exactly fans of L33T but...

For those old enough to recall Harry Hemsley on the wireless ..."What did Horace say, Winnie?"



Thread: Repair advice, please!
25/05/2020 14:07:29

Thank you Duncan,pgk and Ian.

pgk's agri eng route has possibilities being in rural Norfolk. It would be much more feasible if I were a 'Big Cheese 'spad'.

Ian - your experience is what gives me pause for thought!

The 'quality engineering' solutions suggested above would be nice but my lifetime addiction to 'good enough for Government work' standards is urging me down the epoxy (maybe modified with small securing screws) route.

Back to thinking!



25/05/2020 11:43:58

Many thanks, Clive, for a most comprehensive reply. On a personal level, the major caveat is that I have NEVER welded anything and mid-eighties manual skills and sight aren't the best basis for learning!!blush If we weren't still in lockdown, it would prbably be worth hiring in a competent welder. The chopped-up tube 'patch' I saw as an alternative but needing reliable high strength attachment methods - hence the 2 part epoxy thought.

Ron Moody's Fagin probably sums it up nicely ..."I think I'll have to think it out again!"indecision



25/05/2020 10:59:35

As shown in the photos below, my D-W has developed a crack in the motor/head tube support. 'The Gods' were with me, in that I had a steel tube of a very close matching inside diameter which I have mangled into approximate shape.

Question is - which is the best/most 'do-able' fixing method. I have 2 stick welders and a Lidl's mig jobby, but have never welded anything! 2 part epoxy used to be touted as suitable to repair diesel crankcases and screw attachment would be limited by the thin underlying structure.




Suggestions gratefully received.




Thread: Contacts in a Parkside Charger from Lidl's.
23/05/2020 15:40:31

Re. Parkside batteries - can be problematical!! One area is recharging, where the battery can be difficult to recharge if it goes below a defined value as measured by the internal circuitry. This can be sorted, apperently, by a momentary 'tickle' (NOT trickle!) charge from a higher voltage source.

The other problem is dimensional inaccuracy. I have two replacement batteries which are unusable because they are marginally too big.



Thread: Bumblebee behaviour
23/05/2020 09:34:45

Hornets have been mentioned. The memory bank, full, chaotic and prone to error , says that Hornets are a protected species in Germany ... yes?



22/05/2020 10:09:41

A fascinating insight into another of Nature's essential creatures doomed by human greed. However much scientific expertise informs us of the necessity of such species in the planet's survival, the 'want more' element will continue to pollute in their personal profit taking.

Sitting on the swing seat, in the sunshine yesterday and a little, friendly 'bumble' flew over and settled for a while on my knee - a momentary mental oasis in the daily doom recital.



Thread: Which Digital Compact Camera?
20/05/2020 21:24:59

Steve - I could be wrong but I read Old Mart's reply as being sincerely helpful - as would anyone who has tried to use a compact camera in broad daylight. There exists an aphorism about mouths and feet which might be appropriate!
