Thread: Recommendation for next project
07/02/2021 23:35:18

Brian Rupnow does great plans for a small 4 stroke single cylinder engine .It's called a Rockerblock and it works a treat,I am now building an air cooled verticle engine of his design.His plans are excellent and at a reasonable price,He is also helpful if you need help ,the plans are sent to your computer as a file.The present engine is called a Thumper Rockerblock.The bulk of the aluminium cost about 200gbp.


Thread: Hey you! What lathe? Why?
06/02/2021 12:56:41

I have two Myfords,the oldest has no gearbox and is 63years old .I had it reground at Myfords 2006 and it is still a very accurate lathe .My other lahte is a large bore S7 Plus, which I bought at the Myford closing down sale it is a nice lathe to use for what I make.I made a 2" traction engine but Bought a Ward2A to turn the wheels and you certainly notice the difference in rigidity .I sold it to a factory for what I paid for it 400gbp in the mid eighties. Get the biggest you can accomodate and afford, you have to decide on the size of your projects in the future also.


Thread: JB weld
03/02/2021 23:13:15

I am building an engine with two flywheels with fan blades instead of spokes for air cooling.It has caused me to make jigs to build them.The blades will be spot welded in position. I will use JB weld to create fillets at the joins and was wondering if the JB weld in a small spot will hold the blades whilst they are spot welded.Can someone recomend the correct JB and a supplier.


Thread: Myford drive belt
30/01/2021 11:52:33

Brammer belt, but the one with the metal rivet head if they are still availible ,they are a composite material and give a good grip.I have an old S7 which was fitted with a Brammer belt to stop vibration 32 years ago and is still going.I tried the new twist type of belt on my other S7 but got nothing but slippage,so I removed the spindle and fitted the correct v belt which cured the problem.


Thread: flywheel construction

Thanks Jason,you have to bore the hub to size as there is a jig to make with a 45 deg, slope to fit a pin of 1/2" so that the slots for the blades can be cut in the hub.I will do as you suggest .The jig for welding will be next after the rims.Thanks again.

I am building 2 flywheels for Brian Rupnows Thumper Rockerblock i/c engine.I have made the hubs and am starting on the 6" rims which are joined to the hubs with veins at an angle to make fans to cool the cylinder.These fan blades are welded in both the hubs and the rims.The rims finish at 3/4" and I ask for advice on how much to leave on the rims in case of distortion after being welded.

High Clay and welcome.I too was a builder for 50 years and have been into this hobby since the mid 70,s.Get started and all the help you require will be answered by someone on the forum,you can't ask for a better forum.


Thread: THUMBS
24/01/2021 10:10:58

I have acute arthritus in my thumbs, I can sympathise with you as I have difficulty in turning my rotary table and had to make a 4" hand wheel to relieve the pain.Picking up small items and hand tapping is also a problem,turning feed screws is also painful.I love this hobby,if I did not I would give it up but I will not be beat.All the best to every one and stay safe.


Thread: Myford ml7 about to buy
12/01/2021 15:18:39

My old S7 1957 vintage had a regrind at Myfords in 09 and was 317GBP so given inflation in 11 years I'm not surprised at that price.Well worth the expense and it made a new lathe out of it.


Thread: The Repair Shop is getting to me...
10/01/2021 11:14:42

Money for nothing ,this programe lets people believe this is possible.Have you tried to get scrap from your tip.I got a block of steel 6'*6'*6" from the tip but had to pay the operator 10 pounds to sneak it into my boot without the foreman noticing.The presenters time at the tip is not considered in the costing or the travel involved,so don't kid us it's money for nothing.

Thread: Gloves and machine tools - my stupidity.
04/01/2021 19:34:28

I always use nitrile gloves on the mill and lathe,but on the bandsaw I use a pair of very thick industrial leather gloves which have saved me on occasion.When I used to work I was using a 9" disc cutter on brickwork when finished it was idleing to stop when inatention let it catch my wrist, just missing my artery it ground a groove but didn't bleed ,then I noticed a fibre off the wheel sticking out,this fibre had travelled under the skin nearly around my wrist.I pulled it out with a pair of pliers.A very close shave and another lesson learned.


Thread: face milling
30/12/2020 15:23:19

Tank you all, I was feeding to slow and rpm not fast enough ,it is great to have such a quick response and a great forum.


30/12/2020 10:49:02

That is correct Jason it is 40mm.I have been milling 2" flat mild steel.

30/12/2020 08:12:38

I have a arc euro three insert face mill cutter and using on a SX3 mill.I have been taking .5mm cuts and with new inserts and the head wags side to side at 400 rpm.Is the cut to deep and the feed to fast.I find that my flycutter at 75mm sweep at.5mm and 400rpm creates barely a murmer at the head ,can someone put me right.Feed for both was 1" per minute.


Thread: Hacksaw blade orientation - your opinion please
12/12/2020 13:38:19

I have used japanese pull saws for years but they were soon used only for bench work as site work was to demanding on the upper arm muscle when cutting tmber.I could see the same being true on a large hacksaw but it would not pose a problem on a junior one.


Thread: Pea shooters illegal
12/12/2020 13:22:14

Back in the mid 50's we used to buy dried peas from the seed merchants and take them to the Saturday flicks.The manager finally told us that they were banned as repeated firing at the film was damaging the screen.The Saturday morning flicks were 6d .

A superb looking engine Brian.


Thread: Governor drive belt
10/12/2020 14:12:54

I used leather from an old handbag strap and if the leather is scarfed it glues flat and it can be cut very fine.


Thread: Rotary Table Chucks
04/12/2020 10:41:55

Mine has a straight bore,so I made a fitting with a threaded nose for my myford.I found that the chuck was not supported enough as it did not sit on the table,I overcame this with a circular ring just a thou, or two above the end of the register of the adaptor and this made for a ridgid set up.I put a centre dot in the adaptor whilst being machined and this helps when centreing the RT.


Thread: co-axial indicators
01/12/2020 16:30:15

The helpful response has made my mind up and I have just bought a new mitutoya lever dti.My old one was second hand bought from a retired turner which came with attachments that didn't fit.A pig in a poke,I felt so stupid that I hadn't tested it before buying that I didn't complain.
