      I recall that you are another ex-BT man so you should know that, when faced with a serious problem, you should always alert higher management – I guess, in your case, she also performs the role of logistics support – so, when things go wrong, blame the storekeeper!

      Your story of a little venture into the world of electronics brought back a few happy memories- from a lifetime ago. I still think fondly of BT – but I'm glad I'm not there now!

          Norman,

          Yes, well, I've made the point that it wasn't really worthwhile repairing them other than for interest. I've also refused to give a guarantee.

          I'm actually an ex_Strowger man who taught himself limited electronic design following a TXE2 course. And yes, I had some good and interesting times – and some bad times. And like you, yes I'm glad I'm not there now, but sometimes certain things happen which cause a certain amount of nostalgia such as passing what are recognisably old UAX buildings such as the one in Glen Dochart. Google Street View has a lot to answer for, sad old git that I am.

          Anyway, should I make this D bit, or should I carry on with installing Linux? Decisions, decisions, decisions. Let's see now, SWMBO is out, and the workshop, er garage, is quite cold with the ½gale blowing under/over the doors. Right, Linux it is.

          Regards,

                I keep droning on about these cylinder heads, so I'd better show some evidence they really exist. This is the state of play with number 4 as of tonight. Still plenty of cleaning up to do, as ell as skimming about 2mm of the top , shaping to fit the block and shaping deepening various fins.

                      Prompted but the arrival of the ignition for my Hoglet during the week I decided to cut the cams today. I used the method described in issue #7 of MEB which gives a curved flank and was very easy to do.

                      First set the boring head to the flank radius, bring the tool upto the work so it touches and then feed in the cam lift, in this case 0.065, do this in stages of 0.010" using the quill to move the tool up & down

                      imag1507.jpg

                      Then start turning the rotary table in small stages, I went for 2deg which is half a turn and just pump the quill up and down and the cam starts to appear

                      imag1508.jpg

                      After 226deg the cam is done except for a bit of hand filing to round the top of the lobe

                      imag1509.jpg

                      Then just reset the start point and height to do the other lobes

                          Nice cam. Very nicely done Jason

                          The Hoglet is a lovely engine, looking forward to seeing more of yours. wink 2

                              Hi Jason,

                              I did mine using a table of angles and heights and a milling cutter. I worked out the heights to give 'sine wave' motion to flat ended tappets – easy with excel, rather than constant acceleration.

                              It was hard work wincing a milling cutter back and forth 720 times with the handwheel (well a bit less as I settled for 2 degrees for some of teh back of the cams).

                              I can see 2 degrees all round would have been fine. My tables would have worked just as well with your method and up/down with eth capstan handle would have been a LOT easier on my thumbs!

                              Are you going to harden them?

                                  Made a start on the big T-nut to replace the existing one, so that I can fit the Dickson (Correct spelling this time) QC.

                                  Used the Boxford shaper for the first time in real anger, and oh boy, do those chips fly off hither & thither, smoking to their heart's content. "Ouch!" or some such word/s as they hit bare flesh!

                                  Tomorrow I will make a chip deflector to stop them polluting everything in sight.

                                  I have a cunning idea for hinges.

                                      Neil I've used both methods, the good thing with this is you don't have to set the x axis 360 (or 180) times per cam just an arbitary half turn of the Rotary table so can almost do it without thinking.

                                      I've hardened the followers so will leave the cam as is, once I have proved its a runner it won't get ru much after that though I expect Jo will want to have a play with it. I have drawn up a different crankcase for when she gets round to making hers.

                                              Hi, well first thing, after a pot of tea of course, wandered down to my local garage to fetch me shopping trolly, after having put the new tie rods on it the other day. I got them to check and adjust the tracking while it was in for her MOT yesterday, which passed OK.

                                              Then after breakfast done a couple of maintenace jobs about the house and then put me new belt, which I collected from the Chester stand at Harrogate yesterday, on my Chester Champion mill/drill.

                                              I then tried it out and milled a short length of 10 X 16mm keysteel to make four T nuts for my mini mill, two with 4mm tapped holes and two with 5mm tapped holes, haven't decided which two I want to use yet.

                                              T Nuts for my Mini Mill

                                              I've got to cut them off yet of course.

                                              Later after the rain, I managed to wash my proper car after going to Harrogate in it yesterday.

                                              Regards Nick.

                                              P.S. not as good looking as Jasons bits, but it fits in the T slots a treat.

                                                Hi, well first thing, after a pot of tea of course, wandered down to my local garage to fetch me shopping trolly, after having put the new tie rods on it the other day. I got them to check and adjust the tracking while it was in for her MOT yesterday, which passed OK.

                                                Then after breakfast done a couple of maintenace jobs about the house and then put me new belt, which I collected from the Chester stand at Harrogate yesterday, on my Chester Champion mill/drill.

                                                I then tried it out and milled a short length of 10 X 16mm keysteel to make four T nuts for my mini mill, two with 4mm tapped holes and two with 5mm tapped holes, haven't decided which two I want to use yet.

                                                T Nuts for my Mini Mill

                                                I've got to cut them off yet of course.

                                                Later after the rain, I managed to wash my proper car after going to Harrogate in it yesterday.

                                                Regards Nick.

                                                P.S. not as good looking as Jasons bits, but it fits in the T slots a treat.

                                                  Spent most of the day fitting a continuous ink system ( Nine inks) to my photo printer. Fingers are now multi-coloured. This qualifies for inclusion on this forum as I took it all out to the workshop and did it there. Just as well too! On advice I first covered my bench with dustbin bags – again just as well! I dread to think what might have happened if I had done it in the kitchen ( which was my first choice)

                                                  Anyway prints are now printed, mounted and ready for an exhibition on Monday. I can forget about photography for a bit and hopefully progress a few workshop projects.

                                                      I watched F1 qualifying and then did a few hours in the local museum BUT I then came home and watched the FA Cup Final and cheered on Wigan. Not bad for a geriatric Scotsman but I always support the wee team. I'll try to get back into the workshop tomorrow after F1.
