|Thread: Grub screws for 16” Colchester chuck|
Looks like the chuck is fitted to a Colchester lathe so I assume it is a camlock mounting, therefore the damage has been caused purely by over tightening, a couple of foot long extension to the chuck key springs to mind.
|Thread: Centec Myford Rodney|
Another vote for selling it, they seem to fetch a decent price.
|Thread: First loco steel choice|
Just looked on Kennions site and it looks like round bar is EN1 or EN8 and flats are listed as EN3, angle etc will also be EN3, if it doesn’t say it is most probably EN3, give them a call, they are very friendly and offer a very fast turnaround on orders, I have used them for many years and never had any problems, I suppose I must now state that I am only a customer and have no commercial connection to them at all.
It is true that you can’t weld EN1 due to the lead content, and is usually sold as round bar, any flat plate is usually EN3 and this is fine for frames and valve links etc. Why not silver solder, much neater than weld.
|Thread: Noisy Lathe Gearbox|
No, sawdust goes into the engines sump, supposed to quieten the big ends!
|Thread: Linked belt for Myford 7|
I have used a link belt on my Myford from the motor to the countershaft, I was not impressed with it, the belt had to be drum tight before it would transmit power without slipping. Maybe I was doing something wrong if I was can someone please enlighten me.
|Thread: Frost steel blacking kit.|
I have used Metalblak cold blacking kits for many years and have never had any problems getting a lovely black finish on steel, the smallest kit is 100ml and is available for about £20 from model engineering suppliers, GLR kennions, EKP supplies and Blackgates, just to name a few.
|Thread: milling crankshaft on cnc mill using A axis|
Hi Geoff, crankpin will be barrel shaped due to your milling cutter being hollow ground by a couple of degrees, you could grind milling cutter truly flat across the bottom or I think you can do another pass around the journals but with Y axis offset by just under half the cutter diameter, this should just flatten off the high spots.
|Thread: Painting fittings|
Metal to metal contact must be better than metal to paint contact so I would say no to painting. I build complete and then strip down to paint rather than paint as I go, reason is that I don’t seem to get any rust in the workshop, probably has something to do with a dehumidifier running constantly!
|Thread: The Workshop Progress Thread 2020|
I’ve got some G clamps 🗜 like those, i was told that you can measure with them as well.
|Thread: Fobco Star 1/2 cap pillar drill|
Considering the age of Fobco drilling machines it’s a pretty fair bet everything is imperial, including bearings.
|Thread: Rob Roy lubricator to valve chest connections|
Cannot do photo but lubricator pipes don’t fit into valve chests, the pipe from lubricator fits into the bottom of the steam tee.
|Thread: Myford S7 long bed|
Wouldn’t really call it an upgrade, depends on the work you do, do you do a lot of long stuff and run out of room on the standard length machine? You say that you will gain a power cross feed, do you do a lot of facing of large diameters, if so it may be worth having but personally I hardly ever use power cross feed, it it is usually quicker to do it manually. You don’t say if the long bed has a screwcutting gearbox, if it does it makes it a more attractive machine, but don’t forget that the longbed machine will be about one foot longer than the standard machine, do you have the space for it?
|Thread: Rear parting|
Pretty obvious answer is to contact Cowells on Monday morning and tell them the problem, they should be able to provide you with an answer.
|Thread: Old Computers - why do people bother|
I would love to have a nice new Windows 10 computer and if someone will tell me that I can definitely run Autocad and Solidworks 2006 on it I will go out and buy one. At present all Cad and Cam is on on XP, one mill runs on Windows 95 and the other on Windows 98.
|Thread: Milling machine & Shaper query|
Spent a few very enjoyable hours yesterday playing with my Perfecto 7 inch shaper, bought it new back in the seventies and apart from a repaint into a Myford grey colour it is absolutely original. The job this time was a pair of steam chests for a 2.5 gauge loco, they only had about fifty thou on each face to come off so a roughing cut all round of about thirty thou and then two finishing cuts, no time wasted because while shaper was doing its thing I was sharpening a few milling cutters. For larger jobs I also have an Elliott 10m, gives a beautiful finish for port faces etc, it’s got a three phase motor but runs beautifully on a transwave converter.
|Thread: Speetol Tap Grinding Jig|
Looks very much like the forerunner of the Clarkson drill and tap grinder. The three positions on the baseplate would give taper, second and plug angles, the protractor thing sets the relief angle and the thing wilt four pegs is for four flute taps, you may have a two and three peg one somewhere. If you send me a PM i will send you a copy of the Clarkson booklet, can’t get pics to work on here.
|Thread: What a nightmare|
NDIY, thanks for the info, I didn’t have a clue about how long it takes to fill a memory card, I like the idea of swapping between a couple of cards. I really must get myself a camera fitted but the long suffering wants the bathroom ripping out and redone so won’t be for a while yet! Also answered a question about scrap cars on transporters, I have wondered why number plates were taped over, never thought about cloning, I must live a very sheltered life.
NDIY, how long does it take to fill a memory card on a dashcam, only ask because I am considering purchasing one. I thought the laws of this land were innocent until proven guilty, obviously not any longer. Because of the attention my property has received from local lowlife scum I have cameras monitoring every angle, I could prove where my car was overnight but only going back a couple of weeks.
|Thread: What geen grinding wheels for tools|
In the perfect workshop you would use a CBN wheel for HSS and a Diamond wheel for Tungsten Carbide, I would think that as Diamond is harder than CBN perhaps all you would need in the average model engineering workshop is the Diamond wheel. Reason is that Diamond is affected by steel at high temperatures, an expert will be along in a minute with a full explanation, I am sure.
