  1. Hi all, felt it was time for an update - I did mention in my previous post that I would concentrate on the ice cream wagon to speed things along a little, but have since found myself working on all three. Made the decision that all three wagons would have some common features and later I will try to individualise each wagon. These three blocks are machined from solid brass and will house the mechanism, which will include a motor with integral planetary gearbox, gears and cams. These 45 tooth - 0.3 module gears have an offset post that will provide movement to steam generated refrigeration cylinders. There will be four of these cylinders on each side of the wagon. The motor / planetary gearbox was purchased from the bay, the 28 tooth steel gear fits on the output on the planetary gearbox. The brass components with the four side holes will house the cylinders, which are in the process of machining at the moment. So far the mechanism hopefully will provide movement to the eight cylinders and two rotating roof fans ( How to create other animations is still to be thought out ). The brass inner will later be clad with 10 thou brass sheet. Pete
  2. I've started work on what will eventually be three animated covered wagon's, these wagon's will run on DCC, and each will contain a small motor and gearbox to animate exposed gear's, lever's, cover's and the little people. The wagons will be modelled in a Jules Verne style with cast iron side's with valve's and pipework. So far , I've managed to complete the chassis for all three wagon's, but going forward, I will concentrate on each wagon in turn. First on the list will be an 'Ice Cream' wagon. Here's a look on the underside of the three chassis's, the frames are live for DCC pickup. The shortest wheelbase wagon in the foreground will be the 'Ice Cream' wagon and will contain a steam driven refrigeration unit. Thank's for Looking.
  3. This should be the last of the tooling I had in mind to build this season, it's an ER11 adaptor plate that mount's on the rotary table and should be suitable for machining romford type axles and steam valves. Construction is a combination of the ER11 collet adaptor and the chuck adaptor previously posted. Clamping slot's added on the Herbert OV miller. A removable dowel on the underside ensures concentricity with the rotary table. As before, the ER11 nut was purchased cheaply from the Bay. Pete
  4. Here's the modification to the motor mount to make it easier to adjust the motor height and tension, this became necessary when I removed the origninal 240V AC motor and replaced it with a digital variable speed sewing machine motor, I've kept all the original fitting's just in case there's a need to revert back. Started with the main block in aluminium, there was only just enough room on the Herbert to drill and ream the 14mm diameter x 85mm length hole - Had to use morse tapered drill's and reamer, no room for a chuck. Managed to find some Clarkson 'C' type autolock collet's on the Bay, so now I can use the larger collet size's. With the main block and an unmade component in Aluminium, the remaining part's were made from mild steel. Here are the main part's assembled, the aluminium extrusion was a lucky find from the scrap bucket. The two steel screw's with cross hole's in the head actually secure the tension of the belt and not the height as might be expected, the height can be adusted with the piece yet to be fitted in the above picture. ( Height can also be set by the mounting bolt ). The original bracket that connect's directly to the motor was retained. Here is the new motor and bracket assembled to the BCA. A closer look for clarity - The modification work's fine, only long term use will prove it's worth. Regards Pete
  5. Managed to make some headway with the BCA tooling so hopefully the machine will be ready to use during the winter month's, still need to do a modification to the motor mount to make it easier to adjust the motor height and I also fancy an ER11 chuck that mounts on the rotary table and is self centred by a dowel. Here's a mounting plate for a 3 jaw chuck that mount's on the rotary table. Machining the plate on the Boley Leinen lathe. Over on the Herbert OV mill - Adding clamping slot's and three holes to secure the scroll chuck. Part's gathered for assembly. Look's like one or two bur's need removing from the clamping slot, but otherise - Done. Thanks for Looking.
  6. Managed to make a few more collet adaptor's for the BCA using what was left of the 3ft of 3/4" dia EN8 bright carbon steel purchased for the ER11 Collet Adaptor, it's a good job that I didn't buy 6ft. Collet adaptor's for a JT0 drill chuck, JT1 drill chuck x 2 and a 4mm Spotting Drill. Three slitting saw arbors in 3/8", 1/2" and 5/8". ............. .... Job Done.
  7. One of the pitfall's with being obsessed with old machinery is tooling, or the lack of it. Take my BCA for example, the machine came with three imperial collet's, an 1/8", 1/4" , 3/8" and a small drill chuck. Recently, I purchased an ER11 collet holder and a few collet's so that I had an improved method for mounting dental burs, small metric cutter's, engraver cutter's and diamond bur's, I use these small cutter's quite often when machining model railway component's. This small adapter was mounted in the 1/4" collet and worked well, but the adapter position could change / creep during machining, so here are a few images as a reminder to myself and hopefully of some help to RMWEB'er's contemplating making a similar collet adapter. 3/4" diameter, EN8 bright carbon steel mounted in the 3 jaw, one end is threaded M9 x 1, the shank is turned to 7/16" dia, end is centre drilled. Setting the 20 deg angle on the compound slide : 20mm movement on the compound slide = 269 thou on the dial gauge. The 20 deg angle added. Using the same 14mm x .75 thread as used on the previously purchased ER11 adapter, I will also use the same 'Nut', which are plentiful on the bay. The die was adjusted so that the thread was cut in three stages. Collet is first drilled and then bored out with the compound slide set at 8 deg. Checking the fit with a ER11 collet. An M9 x 1 split nut is made from a piece of brass, the nut will protect the thread from the drive dog when machining between centres. With the adapter mounted between centres, the shank and 20 deg angular section's are remachined to size. Diameter of the shank is reduced from 7/16" to 10.97mm. Had major delay here getting the tailstock aligned with the headstock. Adding an 1/8" slot on the Herbert Mill. Couple of flats machined for a 12mm AF spanner. Job Done.
  8. Managed to complete all the de-rusting on the BCA jig borer and most of the part's have turned out very nice, only the chrome handle's and pulley wheel showed serious sign's of pitting from the rust. I'll probably do a little restoration on the handle's later in the year. About 1 litre of the 'Evapo-Rust' solution has either evaporated or been wiped off the part's as removed from the solution which is still active. The 'Epavo-Rust' gel was used on the vertical face, extra gel was applied periodically to area's that had dried, other's have suggested covering with cling film to prevent evaporation. The head was totally stripped, here's a pic taken during the re-assemble. The chrome handle's were very rusty in place's and the chrome had flaked, pitting from the rust is very visible. Pitting on the pulley was expected. The head assembly is now ready for installation. Job Done.
  9. Managed to make a start using 'Evapo-Rust', the main slide's were stripped, degreased in 'Gunk', and then emmersed for 24 hours in the solution. The slide I did a pre test on in an earlier post using the 'Gel' product look's a touch lighter grey, so perhap's 48 hour's might have been better. I have some phosphate acid on order so that I can do test's on the slide handles and old clamp component's, but I'm still reading in engineering forum's that metal is edged by a prolonged dip ( just have to try this out for myself). Overall, quite pleased with the result. ................... Just for comparison, a part not yet treated. Pete
  10. OK, After reading through 'Best Method for Removing Rust from Lathe Ways' on this link, I'm a Phostphate Acid convert. Pete
  11. Hi Michael, If that's the case, then I will trust your word and try Phosphoric Acid out on a test piece some time in the near future ( But not on the BCA ). Pete
  12. Hi Michael, The review's I checked out on youtube showed that product's with phosphoric acid were the quickest at removing rust, but they also etched into the metal . I didn't want to do a trial and error study on the BCA so I chose a product tested by many in the engineering forum's to be reasonable safe on the bedway's, don't want to have the bedway's reground afterward's. . I probably use phosphoric acid on rusty garden tools and some hand tool's, but I wouldn't risk it on the slide's of BCA. Pete
  13. Hi All, My BCA suffered badly from a prolonged damp enviroment caused by a leaking workshop roof during the winter month's many year's ago, the machine is still perfectly usable, but visually, all the cast iron surface's have a brown stain. I've now moved the machine into a spare bedroom workshop so that I can continue modeling during the winter month's without freezing my butt off. Now, I'd like to get rid of that brown staining and so decided to search online for product's that might acheive this. Watched and read quite a few review's and decided to give a product called 'Evapo-Rust' a try. Evapo-Rust is a water based rust treatment were the rusted part is emmersed in the solution for 3 - 4 hours for light rust. A guy in one forum said that it was perfectly safe to leave the rusted part emmersed for 24 - 48 hour's, while another member had left a set of collet's emmersed for two week's and found the solution had etched into the metal and the collet's were scrapped. 'Evapo-Rust' also comes in Gel form, the idea being that you can apply this solution with a brush, I purchased a small 236mL ( 8 oz ) bottle for £15.99 ( expensive ) in the hope of doing the whole BCA without dismantling, A test was done with the gel on a small section of the slide, my purchase looked congeiled and may have gone off. Purchased 5 litre's of the standard 'Evapo-Rust' and decided to strip the machine down and do the job properly, the 5 Litres cost £33.0, so a bit expensive. I hope to get the machine stripped, treated and reassembled over the next couple of month's. I'll post an update on how things turn out..
  14. Here's a few images following the construction of a 'Replenish Wagon' for 'Fun Town', this wagon will supply good's to the market stall wagon's parked outside both 'The Mart' and by the 'Cattle Dock' area. The wagon carries it's goods in tray's that match those used on the market stall wagon's. Construction of the model is very similar to the market stall wagon's which have a split frame live chassis for DCC led lighting. Unlike the 'Market Stall Wagon's', care was taken to make sure that short circuits from the buffer beam's were checked during the construction stage, rather than later when the model was nearly finished. This is the first and least rediculous of a four wagon project. What is Fun Town ? : Fun Town is a small table top module that can be used alone or form part of a larger unit, it fit's like a jigsaw piece to the Walls Traverser Cover to create a small 36" x 18" layout over the top of Snitzl Town's traverser. Done so far : Overhead Tram, Jules Verne's Flying Ship, Steam Operated Traverser, De Snitzlton, Market Stall Wagons and a Replenish Wagon. Still to do : Steam Tram, Animated Wagon's, Animated Figue's, Hot Air Balloon, Interior racking & goods for the Warehouse and anything else that may be appropriate, in other words, a bit of fun. Thanks for Looking.
  15. Hi All, Here's a couple of images of the now finished 'Replenish Wagon' for 'Fun Town'. Decided on a partial load so that the racking is visible. Thanks for Looking.
