Good morning guys, Well I finally made a start on making swarf so its nice to be back on the lathe :) Thanks for the info RK - there is indeed always more than one way to skin the proverbial cat. I have a couple of reservations in this instance with Chris's lack of material but that is not...

Hi Chris , I would totally endorse the methods and technique that our friend RK has said. When it comes to the amount of paste it really is very small indeed. However, personally my only reservation is the lap itself. That is not to say it won't work as obviously RK vouches that it does but the...

Hi Al, As a keen advocate of JB weld I'd like to say a cautious yes. I have used it to hold exhaust systems for glow motors together and it has stood up to the heat in that situation without fixings or indeed failure. The Waller engine I built had the steam chest bonded to the cylinder but...

Hi Chris, I don't think I explained the FC3 holder too well If you take a short 60mm long or so peice of steel say 20 mm dia that will fit a collet you have then drill and ream that 6mm. Cross drill that to take a grub screw and that will hold the cutter much more rigidly than a drill chuck...

Hi Chris, Just caught up with this. Glad the plate worked okay for you - I'm a firm believer in them for all sorts of ops. Re the cutter giving you problems looking at the pic I'm assuming you plunged this through like a slot drill (which it is of course) however given you are holding this...

Glad that's of use Chris Something else that may help too is before you do this op is to turn up a slug of ali to a nice fit in the liner and drill the port holes through into it. This will keep the burrs in the liner to a minimum but twist and remove the ali to break the burr after each hole...

Hi Chris - Its all looking very good so far Thm: very nice work indeed. Re setting up to mill/drill your porting. Radially these are not too critical as long as they align reasonably well with their respective passages but relative to each other vertically and to the flange certainly is, for...

Hi Chris, Time depends on initial finish. Tool marks - however fine - soon show up when lapping and it is these that need eliminating. Obviously that has an effect on time. These three pics show the Racer cylinders at three stages You are not looking for a high polish finish but...

Hi Chris - bore size is not so much relevant as is the surface finish inside before lapping. I have four grades 240, 320, 600, and 1000. The 240 is rarely used but does come in handy if there are any tooling marks that are a little too deep. I usually begin with 320 moving quickly to 600...

Hi Chris , Just a point in case you are unaware ... If you are going to use diamond paste for lapping you do need to clean the parts in an ultrasonic cleaner before fitting the piston. Reason for this is that diamond particles will embed themselves into the soft material and will not release...

Hi Chris, The fixture for holding pistons is quite simple to make. A short stub of material - mine are ali and threaded right through to take a threaded rod the diameter of which will take a cross hole to take a pin a little smaller tha the wrist pin. In your case say a 2mm hole through a...

Hi Chris, We used to use Taylor and Jones at work without any problems - I would say that they are certainly suitable for what you need. And yes AG some of the imported ones are very useable too - after all we are not working to aerospace standards ;) As for chucking versus hand reamers...

Hi Guys Thanks for the help Toronto the engines were anodized using red writing ink. Petertha - I'm not very computer savvy at the best of times - get something to work and that's it until 'they' improve matters and make it worse whoever 'they' may apply too. Certainly did with Picasa I used to...

Hi again Chris That seems pricey for a reamer - is that a chucking reamer or one with a morse taper. I have found chucking reamers to be fine and reasonably priced here in the UK. I have a lot of MT reamers but they only get used when theres no chucking one available. The price does usually...

Hi Chris - this is just the way I started out - with just a vertical slide as you have. Not the best of kit compared to a mill but better than nothing at all thats for sure. Here's another alternative method - Providing your piston is finished to length (OD is not important at this stage - see...

Hi Chris, Thanks to some help on here I've sorted out how to get pics up -thought you would still like to see this Regards - Ramon

Hi Chris, If you haven't turned too much of your CI stick down you could save on material by this method ... cut off a couple of slices say 12 thick then cut each side of the disc away to give a 30mm long square stick with slighly radiused ends. Pop in the fourjaw and bring to round section as...

Cor isn't it easy when you know how :rolleyes: Thanks Toronto I can see it now. What hadn't registered is that if you right click in the bar to the right of the highlighted 'https' it de-selects it and the URL fills the space making it disaappear. I had to have a few more goes before I...

Thanks for the response guys but niether works I'm afraid :( Just tried both methods - and double checked them - and all I get on preview is that little white square when posting the URL or just the text if using your suggestion Thayer. Could it be something to do with the new arrangements...

Is there really no one out there that can help me here :confused: This is the result of pasting the URL of an image previously posted on here in the Super Tigre thread. Somethings changed as instead of getting the [img][img] brackets I now get a 'insert URL here' box but I'm dammed if I can...
