|Thread: Over 70 Driving Licence Renewal|
Bernard You will find you have lost several categories, trust me I did all of it 2 years ago ! I still have 7.5T You won't now ! Noel
|Thread: Is this a record fuel price ?|
Reportedly £2.03 in Kings Lynn
|Thread: Over 70 Driving Licence Renewal|
IF you want to RENEW your old license at 70 or older you will need a medical and eye test ! You will LOOSE numerous categories if you do it on line. It will be a NEW TYPE of license and may affect driving anything more than cars and light vans, larger motorhomes Etc you will loose. Be warned ! Noel.
|Thread: Myford Lubrication Oil|
Back in the 50/60s normal SAE30 mineral engine oil was used as 2 stroke oil, BSA Bantam Etc ! The use of Chainsaw chain lube oil on other things, be careful as it is fed into the bar groove and works through the chain, carrying the sawdust and grit etc away. It is a pumped constant feed system ! It is not intended for rotary motion and once spun out will leave journals dry, It is a specialist lube not listed for any other use including those above. ISO 32 and 68 hydraulic oils are readily available and if one considers that pumps and motors are machined to microns for rotary motion and cylinders are linear motion then these 2 specs are the ones to use on our lathes, mills Etc UNLESS a special oil or lube is secified ! There are several threads on this matter. Noel.
|Thread: Drilling 38 x 1.5mm 316 polished stainless tube.|
Dot punching stainless is not always a good idea and IF you use 4facet or split point drills you should not need to ! A jig would be a good idea and definitely use cutting fluid Rocol RTD - it is expensive but the spout allows for very little wasteage, you only need a drop ! Doing this by hand is not going to be easy or accurate I would consider a bench drill and generator if IN THE FIELD.
NEVER DRILL STAINLESS WITH A BLUNT DRILL, or you will need carbide to finish ! Good luck Noel.

Take the advice so often given here ! JOIN A CLUB ! A GARDENING CLUB, THE RHS WILL BE ABLE TO GIVE THE NAME OF YOUR NEAREST !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Noel.
|Thread: At my wits end trying to remove pulley|
Multiple cycles of heating and cooling may work, the expansion of alli is far greater than steel. Proper puller , but be careful to pull on the centre NOT the edges of the pulley ? If hole in pulley is right through, using stout flat or angle iron bars to support the pulley and beat it out from the top, place something underneath to catch the motor. The motor is REALLY dead ? or is it repairable ? If you were near me I have hydraulic pulling and pushing kit ! Noel.
|Thread: ML super 7 belt|
If you must use a link belt then order 1m it will be more than enough ! Though dismantling the head stock is not hard and resetting the bearings is easy - you will learn a useful skill that will make sure your headstock is properly set - it may not be so now. Noel.
An interesting spot on Radio 4 today on the damage being done to the brain by covid, more so at age 70+. Noel
|Thread: Don't really know where to Topic this.|
PRICELESS ! Noel.
|Thread: ML super 7 belt|
A ) Don't use link belt B) you need an A29.5 belt any good transmission/ bearing supplier will have one, just called my supplier LESS than £4 +vat. Noel.
|Thread: Boiler making torch|
Seivert or bullfinch are both good names. If buying a starter kit make sure the regulator is big enough for the biggest torch you will use ! As a propane bottle is used, especially with a big jet, it will freeze and you will loose bottle pressure, the bottle may have plenty of gas in - it just can't boil off, bigger bottle less trouble. I would say use a 13 or 19Kg ! 3.9Kg is too small! Once below 1/3rd on cold days you may have to warm the bottle, pour warm water over it, DO NOT wrap it in a blanket ! If your near N Norfolk I can find you a bottle. Noel.

|Thread: FOR THE EXPERTS !|
Gentlemen, further to the above, the engine went away ! One liner was pinholed ! The rest were not good ! The engine had it seems ingested sand which had caused damage to the top ring and groove. All in all a sorry state - and now at 50 years old there are problems getting parts ! Ah well. Noel.
Sadly an all to common situation now a days. I recently bought and transported a complete workshop to help set up the 18 year son of a friend with a lot of what he needs to enter the world of engineering. What sort of mill do you have ? Noel.
|Thread: Spark Erosion Machine|
I'm not aware of the EIM circuit, tell me more ?. I used a pair of one armed bandit transformers that gave me 66V at 8A or 100V at 3A, plus 12V for the control circuit. Look at the tread on here on EDM machines, page 2 at 07/05/2021 at 21:50 you will see a brief rundown on my machine and pictures. A golf buggy charging transformer will give about 55V at up to 20A and be rectified ! The Ben Fleming design does have a short coming that was solved by Jeff Daymans modification. Noel.
I have buit what turned out to be a good machine ! USE ANY transformer that will give you 50-100V at 3A or more. NOT an auto transformer ! IF you have 2 identical units that are not high enough voltage then they can be linked in series to double the voltage. If you want more info come back to me ? Noel
|Thread: hi from Belfast ...|
My curiosity got the better of me and I bought this item ! The Myford swiveling slide is remove. As soon as I saw it everything fell into place ! The "handle" is a Myford driver plate, This is screwed onto the spindle that runs through the bearings, the spindle is Myford form. The other end of the spindle is 5/8" and keywayed with a fine threaded retaining cap ! The 2 "belt pullies" are carriers with loose bushes 5/8"dia and keywayed and the pointy item is a detent. The gear holders are long enough to take 2 wheels. There is a lock on the spindle and a pair of stauffer greasers. It uses Myford change wheels. All neatly made
USE ! Using the 4 bolt holes, bolt down to a machine. Attach chuck or face plate to the spindle nose to hold the work. set up a gear train eg 40t on the detent, 20/60 X 25/75 and you have a dividing train of 360 divisions. Not sure what I'll use it for but very interesting. Those of you with a better imagination than I may choose to send ideas as to what ! may use it for ? Noel.
|Thread: Backyard Foundry - oil burning furnace - moulding and casting a spider|
Good morning Gentlemen, a beautiful sunny day here in Norfolk. On the subject of polishing castings an easy way to make a polisher is to find an electric water pump, Say 1/2 to 1.5 Hp normally they will be 2pole 2850RPM single phase. Often scrapped as the pump or seals have failed or simply as the system is being upgraded. Dismantle the pump and disguard BUT keep the impellor.. IF flange mounted then mount on a heavy piece of angle iron or such or strap to a C shaped cradle that can be bolted down. Some alli cased motors have small cutouts that hold a nut enabling a foot to be bolted on. Buy a pigtail, the pointy bit with a screw thread, but make sure you get the right hand so the polishing mop screws ON not OFF !!! Take the pump shaft and measure it and check the thread, now drill or bore in the lathe, may be 1" deep then tap to suit thread.. Screw on pump shaft and check for truth. with the reads running the right way there is no need to grub screw or loctite. DO NOT reverse the direction of rotation as this will allow the pig tail to unscrew OR you will need to secure !!!!
As always the Lord smiles on the righteous, one day awhile back I found 3 dumped, from a swimming pool, one even had a new 20m 2.5mm extension on it., all were 2Hp It did matter as I already had made one years ago but good stock ! If dumped because it was noisy it will have an easy to get bearing set so worth fixing..
The polishing Shop are very helpful for pigtails I would go for about 1" (25mm) dia and 3 wheel types in 6" x1", sizal, stiched cotton, and loose leaf. Each used with it's own grade of soap, coarse for as cast, medium for a good lustre, and fine for a super finish. Axminster also supply all you will need. ( I have NO connection with either firm )
Polishing is a VERY DIRTY job and can be dangerous !!! Sharp edges should ALWAYS face away from the wheel. On finely detailed work it may be a compromise as the buffing soap is very agresive and will destroy detail. DO NOT dwell on a single point, keep the work on the move and avoid allowing the wheel to funnel into a corner or it will cut grooves.
Have Fun. Noel

|Thread: New Member Greg Savage|
Welcome to the party Greg, can't answer your question but I'm sure somebody will be able to. Best wishes Noel.
|Thread: How hard is gauge plate?|
You will struggle to make a thread with only plug taps ! If you use a larger drill you will reduce the engagement to a point the thread may well strip with little load. Good luck. Noel.
