|Thread: Slight repair required|
With over 3000 hours helo time on a wide variety of such, I would have found some excuse to avoid the Piasecki 'Flying Banana' even in pristine condition - that particular piece of (possibly) mag alloy would best be left 'as is' as a warning!!
|Thread: Scam alert|
Maybe I have misread/misunderstood some of the responses on this thread, but it appears that a phone call is answered and the unconfirmed ID caller instructs the recipient to "press 1" ... and they do just that!!! Am I misreading something here?
|Thread: Bandsaw woes.|
Robin - I have that same model from the same supplier. I would rate the chances of obtaining a 'straight' cut (in anything) as close to zero. In fact my particukar machine was sold at a discount as being "incapable of adjustment to correct cut by our engineers"! I occasionally manage a vague vertical but there's never going to be a 'no-fettling required' result. It is, therefore a muscle saver for crude approximations only - matches my skill level!
I wish you well with your endeavours and will follow closely
|Thread: Wobbly Kitchenaid Mixer|
Loctite certainly does go on and on - mine bought part used over 20 years ago, still working. Keep Super glue in the refrigerator.
|Thread: Hi from darkest Norfolk|
Welcome from NR12.
|Thread: Calling all Stirling Engine enthusiasts|
Gray - one from Professor Senft, maybe?
|Thread: Classified adds|
Clive - may i make a simple request ... if you gat a reply from any ads you place could you acknowledge them, please? It appears, nowadays that this particular courtesy is being ignored!
|Thread: Greetings from Edinburgh and advice about Unimat Model 3 Lathe needed|
Thought 1 - overpriced!
Thought 2 - when purchased, it surely must have had the basic chucks and tooling , so these have been stripped out for extra profit .
Thought 3 - you may well be a 'natural' machine user - I
Thought 4 - If possible, find a local ME club and join. Get all the advice you can and, you could well find a useful 'starter machine' for sale within the membership.
Thought 5 - My 'contributions seem to be negative ... only so because a bad move now could sour your enthusiasm and that would be a shame.
Keep asking - the answers may well be unwelcome but they are well intended!
Just a PS re. the Cowells - the listing doesn't specify whether it is a 14 x 1.5 or a 14 x 1mm nose thread. For accessory availability that is important!

Hmmm - in principle, it would suit some of your wants - (owned and used one for over 20 years and have 2 plus at present) HOWEVER, there appears to be a bidding war on that one and, for what's there, the price (at the moment) is excessive - No milling support or head or accessories. Unimat 3s are nice little machines as combined mill units but not terribly special as 'stand-alones'. I have a Cowells, Pultra and Taig/Peatol for comparison. The Taig has (in my opinion) advantages but if a Cowells was out of the question, I would look at the Sherline as next option.
As to skill progression, yes, the U3 (or similar) will introduce you to metal-working basics but techniques don't (for me) read across to my ML7. Lack of rigidity and limiting cut depth mean extended working time but may not be a factor for you.
Any further questions, feel free - on here or PM
|Thread: Aircraft General Discussion|
No doubt Ian SC will be aware. **LINK**
|Thread: ML7 Countershaft|
Mike - 19.00mm or, more likely 3/4" in old money. The uncertainty is because I have a clutch unit and the only measurable bit is a sliver on the outboard end. HTH

|Thread: This weeks offer at Lidl|
I assume that there will be a number of members who own Lidl battery powered tools. I have several, including those with the 'triangular' battery pack. Replacement battery packs and chargers have been on offer recently so I bought a 4AH battery and a 2 AH battery and charger pack. They are incompatible with the previous versions! The problem is size - the new versions are nearly 0.5mm too large 'across the corners'. I've managed to get the 4 AH battery to fit in a screwdriver by loosening the body screws but the combined pack charger will not accept the old battery. Very much caveat emptor!!
|Thread: Ml7 New Owner.|
As Howard points out, the faceplate gives you considerable increase in swing. Re. speed control. I cannot recommend too highly fitting a VFD/3hase motor combo. Transforms speed control (even pn my TriLeva)
|Thread: What Did You Do Today 2019|
Not today but yesterday - JUST in time for intended recipient's arrival! Intended as a memento of a 'mature' first solo and the aircraft plus the Naca 43012 aerofoil which supported him! He was very surprised and seemed pleased. Yes, that is intended to be a 'Black Box'! The whole thing just developed from a quite different original idea and generated more problems than almost anything I've done previously!
All construction materials from offcuts/ scraps/Os&Ssetc. No skill or ability for engraving, so made a waterslide transfer for the plaque.
Definitely not one to repeat!
|Thread: Indoor R/C Flight & a whole lot more|
Quite extraordinary!! The last indoor I went to was in the 80s, in the big hangar at Cardington - a rather different offering! IIRC we had the first demo (for the RAFMAA) of an R/C indoor model - balsa and microfilm and rudder only. How times have changed!
Most amusing? - the 'witch', of course. Most eye-watering? - as an ex-helo man, that demented green 'thing' at the end of the clip!!
Some mind-boggling aerodynamics going on there - excessive electric power, of course, but the low speed stuff and controllability of the Antonov, ATR , Horton twin jet and the Viggen etc.would make some very interesting Perf plots!
Thank you Jason
|Thread: What is it/they called?|
Thank you Bazyle - that's what I assumed originally ... except that there is NO drawbar! Also, the lack of a 'proper' centre hole at the tool end means it can't apply pressure from there. It is a fairly complex item to manufacture with the internal rod securing the cutter using the knurled portion. All very puzzling!
Been trying to find info on the following 'milling cutter' (??) , without success. The cutter bit is held in position by a central plunger tighhtened by the knurled portion. It will only fit to cut TOWARDS the taper mount. There is a slot in the knurled portion to allow a pin to be drifted out to split the shaft. The taper is friction fit only, so cannot provide cutting pressure for the blade. there is a hole at the cutter end but not suitable for a centre. Approximately halfway between the knurled portion and the cutter there is a groove which is fitted with a spring ring. All in all, a total mystery! suggestions would be very welcome!!
|Thread: Polishing Acetal/Delrin and other plastics|
Final gloss finish using Jeweller's rouge, perhaps? or, for cheapskates like me , toothpaste. Won't do for anything other than the very fine stage. Use to use it for watch glasses.
Trevor - presumably yours, like mine, are only suitable for 4 flute taps?
Having just broken an 8mm tap (best quality Chinese black chocolate!), this thread offered various 'escape' options. However, from the dim recesses of my remaining brain cell, I recalled a couple of oddments from 40 or so years back - see pic below.
The smaller of the two was adjusted to fit and ... Bingo! . It unscrewed easy-peasy!
I cannot recall having seen these mentioned previously nor seen them advertised. Anyone else own or use one?
