Thread: Tiny split pins. |
14/12/2019 13:13:21 |
Thanks , I did not realise you could buy them that small . That said I think mine will need to be a little smaller than 1/32 so I will get some wire. Thanks for the offer Chris |

I have been making some M3 castle nuts which will require split pins when fitted. What is the preferred method to make tiny split pins |
Thread: What would you call this tool |
11/11/2019 14:55:39 |
OK interesting thoughts, thanks I will have to have a think about it now although its probably a bit bulky for my mill. I will make some measurements tomorrow . |
11/11/2019 13:09:19 |
I bought this at Action a while back and don't seem to have any use for it so might sell. Not sure what to advertise it as , it has a Parvalux geared motor so turns the chuck fairly slowly. |
Thread: Anybody made the Les Chenery Gypsy engine |
11/11/2019 12:48:52 |
I am just starting the Rocker posts this morning , like you say it will give me an indication of valve length when i fit them. I sent Mike a private message through MEM but got no reply so i thought i would try here. |
11/11/2019 09:52:25 |
I have just made the valves for this engine and they appear to be too short. I have checked the plans and the dimensions I used seem correct so maybe the plans are at fault. Just wandered if anybody can remember having an issue making this engine. |
Thread: Recomend me a slitting saw to cut these fins |
04/11/2019 21:05:11 |
Well its taken a while but finally completed five cyl heads [ one spare]] I found the best cut was made using a 'climb cut' I just tightened the jib strips slightly . Also seemed to cut cleaner with a dry cut or very little fluid, less grab for some reason. Not the most exciting job , just put some music on and got on with it . |

Hi , will one saw be able to cut the fins in four cyl. heads without loosing its sharp edge. thanks |
07/10/2019 13:33:11 |
I need to cut fins into an Aluminium cyl. head the same as the one below. Which type of slitting saw would be best, number of teeth ect. The Saw will be 1/32 thickness

Thread: Plugging crankshaft oil ways |
26/09/2019 20:19:16 |
Hi Howard , yes that's the sort of plug I was thinking, I don't think the oil pressure on the little engine will be too high to pop a plug out. |
26/09/2019 19:08:39 |
Thanks for the replies, I do not think tapping and grub screws would be practical , I was hoping there may be a soft plug I could use and press in. Those Expansion plugs look good , I will read up on them. |
25/09/2019 13:47:32 |
I made the crankshaft below and cross drilled the oil ways which now need plugging. What is the preferred method of plugging these holes, they are 2mm and 3mm diameter. |
Thread: Where can i obtain these brass unions |
16/09/2019 19:39:41 |
OK Thanks , I will make them , just thought I would ask just in case. |
16/09/2019 09:23:28 |
I need to make some oil lines for my model like the ones below. Can I buy them or do I need to make my own.

Thread: Any uses for an old tired lathe bed |
03/08/2019 19:39:29 |
Posted by Pete Rimmer on 03/08/2019 18:45:27:
My first scraping project was a S7 bed. The simple shape makes for a great first project. That's an idea , I might have a go at scraping it. |

Did you replace it because the old bed is beyond being reground? If there is enough meat for a regrind then it may have some value to someone. Maybe a super long bed could be rigged for making cues or the like. Mike The problem with a re grind is the cost , I managed to pick up an excellent second hand bed much cheaper than a re grind |
03/08/2019 16:49:43 |
I replaced the bed on my Myford S7 a while back and the old bed has been sat under my bench ever since. Before I have my next tidy up and take it to the tip is there anything it might be useful for. |
Thread: Crucible for annealing cast iron piston rings |
18/07/2019 20:14:40 |
Thanks John, would be useful but I can probably work it out for myself if I need too so don't spend too much time looking. |
17/07/2019 14:31:51 |
Also does the crucible have to be made out of cast iron or can I use steel |
17/07/2019 14:02:31 |
I made some piston rings for my Gypsy engine and I want to heat treat them using a crucible [Trimble method I believe]. Reading on the internet I see reference to a formula which gives the dimensions of the crucible for a given ring size, does anyone one know were I can find this formula? |
