Re: Printed wheels

Never mind wheels, how about a complete set of working valve gear, rods, and cylinders!! PBM You might jest, but I got into this printed (sintered) metal stuff from talking to a fellow modeller who was printing 2mm scale narrow gauge loco chassis with functioning compensating beams in the print... ...

Re: Printed wheels

I note that the 2mm society are producing a new style of wheel. It is worth mentioning that the 2mm Scale Association are now using 3D printing for locomotive wheels. They are printed in stainless steel by a firm in (I think) the Netherlands. https://www.rmweb.co.uk/community/index%20...%20nt-38267...

Re: Lever Frames

I've built a couple of these recently, starting with the MSE kits. Ended up ditching the whitemetal middle bit, and scratchbuilding that from some U-section brass (cut down some rectangular tube to get the section needed). Much easier than drilling holes in whitemetal !

Re: Mitchell Castle battery/radio control

I'd have used a slightly different switch arrangement - a SPDT (aka "changeover! switch), so that in one position it would connect the charging +ve to the battery, and in the other position connect the battery to the receiver(and rest of loco). Thus the loco must be turned off in order for the ...

Re: Loco current consumption tester

Hello Nigel Thanks for your quick response. The ammeter I have is a 0 - 5 Amps range and the voltmeter is 0 - 30 Volts. The ammeter reads in .2 Amps stages. Regards Sapper Many motors used by S4 modellers are quite low current consumption, so 0.2A may be more than the motor is consuming. One way to...

Re: Loco current consumption tester

circuit sketch is fine, but lacks details of ammeter and its performance. So, what ammeter do you have ?

There are several mentions of hand-drilling arrangements to achieve vertical holes in the thread above.

Re: Jig for drilling crankpin hole

I suppose the other option would be to go for a lathe. I understand that you can accurately drill and mill as well as turn albeit less conveniently? Its just that the MF70 seems ideally suited to very fine work and would give both a drilling and a milling function in one? Hey Ho ... decisions decis...

If the MS104 is the same as other stands I've seen to that design, then the Proxxon MB200 stand is substantially better engineered stand. I've found MS104 style stands to be OK-ish, whereas the MB200 made me question whether there is any sense in buying the dedicated TBM220 pillar drill over the MB2...

Re: Jig for drilling crankpin hole

I'd caution against the MF70 as a drilling machine, because of the lack of lever feed. As a light cut milling machine its good, but it is light cuts only with quite small cutters(*). For some years I had, on loan, the rather heftier Cowell's small milling machine (and a very nice small mill it was!)...

Re: Jig for drilling crankpin hole

Yes Will I agree. All I needed here was a way of holding a hand drill vertical. Wonder if George Watts could come up with something. His quartering jig is just so clever - and only half the price or less of a RTR loco. Approaching 30 years ago, this was written up by Pete Wright in the 2mm Scale As...

Re: Adjustable trestles

I've seen a large layout use similar trestles, but fit an additional beam to the upper beam, and provide that beam with simple screw adjusters up/down. Similar in concept to the adjusting pads Mark shows in his link, but an entire beam over the width. I might take the car down to Lidl tomorrow at £1...

Wobbly crankpin: bodge+hope method - devise method to hold pin in correct orientation (or as near correct as you can get) and use either retaining compound (eg. Loctite 603) if the gap isn't overly big, or expoxy resin (araldite type stuff, but pick your grade carefully) to secure pin. engineering m...

Options I can see: 1) Wait for it to dry. 2) Wait for it to dry, but also add weights to flatten it. 3) Glue some matching foam on the other side with similar quantity of glue (as one does with plasticard to even out warping) 4) Make a vertical piece to glue to the underside, to form a T-section bea...

Re: Exactoscale wheels and axles.

Yes, 601 and 603 are available. 601 is expensive, and overkill for the job. 603 a more sensible price, and arguably a saner choice. Its holding a plastic model train wheel on a metal axle, not fixing a bit to a full sized airliner. So, if lacking 601/603, then I'd use varnish, shellac, runny supergl...

The models are rather nice - or they will be if assembled like the test examples Chris had at Workshop Wise in Northumberland a few weeks ago.

From a very quick measuring, there is room for sound chip, speaker, etc.. in the bonnet area.
