Thread: Colchester Headstock Sleeve
27/08/2018 17:47:05

Good call Neil, just tried a 5mt -1mt reducing sleeve i had lying about and it seems to fit perfectly. No good for my purposes, but proves a point. 👍

Now here's a knotty little riddle.

My Bantam 2 has a bastard size taper up the head stock, which is rumoured to be MT4.5, or some such. It seems Mr Colchester didn't want us buying standard fittings so he made the head stock a funny size, though it may be something to do with the size of the bearings carrying the head stock. Mr Lathes.co.uk has got some comments thereon.

Anyway I'd have assumed that your Student was the same, but it can't be. I made a bush for my Bantam, but it's 1.517 - 1.362 by 3.07 ins long.

However, when I bought the lathe I was given what was supposed to be the "right" bush, which is much too large. Squirrel that I am I've kept it, and it is 1.809 - 1.656 x 3.036 long. All these dimensions measured with calipers, so somewhere handy but not precise. While those dimensions aren't exactly what you've shown above, they look something useful.

You are welcome to try the second bush and see if it is what you are looking for, send me a PM with your address and advise so on here and I'll pop it in the post next week.

Hope this works! Rgds Simon

That’s very kind of you Simon. Interestingly the dimensions you have given are remarkably close to one on ebay. I suppose the slightly larger fat end could account for the bush sticking out a bit. Will drop you a PM.

My Student 1800 was missing the oft misplaced tapered Headstock bush for turning between centres. I bought one off ebay a few years back and popped it on a shelf.......came to use it today and of course it’s the wrong size dont know.

Questions are.

A- Does anyone have the correct one lying around they wish to sell? Or know where i might obtain one.

B- Any idea’s what the one i have is off. Dimensions are 1.622” at the fat end. 1.500” at the thin end. 2.490” Long. With a 3mt oil upt middle.

There are a few on ebay, but at least two which are advertised for my machine, clearly are not, so i’m a bit wary, twice bitten and all that.

The hole in my headstock measures 1.766”,bit awkward to measure the far end hole, but approx 1.675” with the bush being around the same length as the one i have.

The event which pmm1 refers to is run by the Vintage Sports-Car Club. I was until recently a member, but when I discovered that they were running (other) events outside the law, and were not prepared to do anything about it, I left. So, they are unlikely to be helpful to anything I say.

It didn’t involve meeting in a McDonalds car park did it smile p

Well OP, if it represents such GVFM i think you should buy it, then you can be the first to do a review........i look forward to reading your evaluation wink

The reason I ask is they come up a lot, seem GVFM but cannot find any reviews.

Things that come out of China that seem GVFM are usually not.........

And where is the palaeontological evidence that dinosaurs had wheels?

 

Well the latest scientific research suggests Tyrannosaurus had Feathers, and 'screeched' rather than 'roared" so maybe the discovery of a set of brass wheels could be just around the corner cheeky

Heller drills seem good quality for the price....i buy them from my local fastener stockist, but they are widely sold on ebay.

Thread: Reverse engineering
17/08/2018 17:41:15

I'm also mystified......but there's nothing new there

One thing i can say with some certainty is the carb body will most likely have an external thread. So sticking a dowel in is probably not an option.

It's usually a fine pitch, which i suppose narrows it down at least a little bit.

Edit: Just been and measured a 1930's Amal.....there is only about a 1/4" of thread on top to measure, but it looks like 55 degree 24tpi

A quick google brought up this old thread https://www.model-engineer.co.uk/forums/postings.asp?th=127000

Yeah i would treat that one with suspicion......even the serial number will only confirm the age of the bed.

Saying that i wouldn’t get too hung up on age, have recently picked up a 50’s Myford and it’s the nicest one ive ever had (and iv’e had a few).

The later ones are desirable for the larger headstock bore and powered cross feed, but doesnt mean they might not be worn out.

Buy on condition not age unless you truly need the later features. The one i have will be for sale soon, but is very well tooled and as said in great condition, still wearing original Myford paint, so possibly out of budget. Drop me a PM if you want more details, photo’s etc. Kettle is always on if you fancy a look.I’m in Leeds btw, so not a million miles from the ebay one if you did wish to compare the two.

Just an update, to thank everyone for their help. Turns out i had wired it correctly, must have just been bad luck that the capacitor decided to self destruct. Fitted a new one this morning, and checked with meter that it was dropping out in both forward and reverse directions.......All good, and no smoke escaping. cheeky

Thread: Crankshaft repairs
07/08/2018 00:03:19

Posted by John MC on 06/08/2018 17:53:07:

OP, are you sure the fit is not the usual Veloce slow taper? Many years ago I repaired a Mk1 KSS crank that had suffered they same as yours. Straight forward turning job, all the diameters can be turned at the same setting ensuring concentricity. What I had to do was bore the holes in the flywheels, both damaged. I bored them just enough to remove the damage and counterbored to take a "head" left on the inner ends of the shafts to stop them pulling through the flywheels. this approach avoids the welding approach. If you do bore the mainshaft holes this must be done with great care, setting up off the crankpin hole, get this wrong and the crank will never true up on assembly.

I believe Alpha are not trading at the moment, hopefully to return soon.

I would disagree with the "aftermarket scene" for post war Velo's being huge. The main supplier is not getting any younger and would like to retire. Anno domini is making itself felt with four other specialists (repairers). Some other classic bike dealers sell the common stuff, the more specialist stuff will become hard to get unless someone picks up the reins, may be the owners club?

Its also been mentioned someone is making complete engines, not quite but I believe that is his ambition. The price will mean that very few will be able to buy these parts.

John

John, i was trying to convey the difference in aftermarket spares availability between early and late Velo’s. Maybe i didn’t word it very well. The MK1 KSS gets very little attention, even compared to the MK2, so the aftermarket scene for Viper and Venom parts is huge in comparison.

Yes i think you are correct about the slow taper. The mainshaft bearing is described as having a 1 thou to the inch taper, which is probably why i struggled to measure it from the old shafts. Incidentally that single bearing is £185 + vat

This got me thinking, if im going to the trouble of making new shafts in modern material, then why not modify them to try and improve location. Your solution of adding a head and counterbore had crossed my mind, however i did wonder if this might weaken the crank halves and should they too be remade in EN24t.

if i did go down this route, i wonder if the shafts could be made plain with no taper, just an interference fit and tig welded on the back side, then a more common bearing used, (which should hopefully be cheaper ).

I would be interested on your thoughts.

06/08/2018 15:14:08

Thanks for all the suggestions, reckon i may as well have a go, no point in having the machinery otherwise..........need to find a supplier for the main bearings first though, which at a quick glance are roughly £100 a piece disgust

With all the cottage industries serving the vintage bike scene these days, I'd keep looking around for replacement parts. There must be some out there somewhere, or somebody making them. What model Velo are they from?

Edited By Hopper on 06/08/2018 01:57:21

Concur. I'm not a Velo man either (not thru lack of trying - love 'em) but i have seen lots of specialist Velo people in the classic mags.

Hell, not only have i seen 5 speed box upgrades, but 6 speed too. Belt drives, alternator conversions, electronic ignition, and now having thought about it, a guy is building and selling complete engines. So somebody is making crankshafts.

OP just needs to look harder.

Agree the aftermarket scene for 60’s Velo’s is huge, not so big for pre war machines. Also those lovely aftermarket cranks you mention are generally full units, splendid things indeed but ££££
