I also read that he had asked Jools Holland and Roger Daltrey (both railway modellers) to do the same.

Thread: Class 22 Diesel (next project)

Still working away on the chassis so I thought I had better get the buffers finished. I was going to make them one piece but went for a separate base plate in the end. The fixing bolts are dummies (5BA) and not even threaded, I drilled a close fitting hole and fixed them with 638, the buffer assy is fitted to the chassis with a single M6 cap head.

I started a bit of light weathering on one of them and will do more when I weather the buffer plate. I am quite pleased with them though they are not perfect but the best I can make of them.

Thread: Rake angle on Cutting Tools.....memory tips???
22/11/2019 08:52:47

With the bit of experience I have picked up so far I dont get hung up on the angles and when I grind a HSS tool I just go with what looks about right and it always seems to work. I am starting to lean more towards insert tooling though, I have MT inserts for general turning and my parting is an insert tool plus I am about to get some GT inserts for non ferrous.

One thing that did jump out at me on Jasons link and the LMS link to recommended angles for different metals was the 35 degree back rake for aluminium, the tools I have ground and used have nothing like that probably around 15 degrees not that I have measured but they have seemed to work ok.

Thread: Lathe belt broken
21/11/2019 14:30:35

Yes Bob will be using a Gates 5M JB Polyflex belt and the spring loaded tension roller on the 920 lathes does run on the outside of the belt. Despite Gates recommendation not to have outside idlers one can only assume that the original design of the lathe ignored that recommendation. Having said that and based on my Warco 918 (920 lathe) I can only think that the lathe designers got it right, there are thousands of 920 lathes around the world and I have not heard of belt problems being an issue.

Unlike what Mike W1 found on his machine the tension roller, the sprung lever and its mount on mine are all square, aligned, well mounted and the belt runs true between pulleys. I have bought a spare belt for mine but thats only to cover the need of a replacement which with sods law is bound to come on a Friday evening. I dont know how old the belt that came with my lathe is but I know its been fitted for quite some time and still looks in very good shape.

I dont think there is need to start delving into mods to the tension roller, there is no need it works just fine. Providing it is all good on Bobs machine he just needs a replacement belt of the correct length. Bob couldnt use the tension roller because the belt he had was too short and was difficult to fit on and off the pulleys which is what caused the belt damage.

My two penneth anyway.

Bob why are you not using the belt tensioner as Bill says that's what it is there for. I have the Warco 918 and the belt I use is 5M but the 730 not the 710 so is a little longer. Belt changing to a different pulley size is a doddle, push the tension lever back, belt becomes slack change belt position release the tension lever and that's it quick, easy with no stress to the belt.

Thread: Milling for beginners

Jason, I have just read your latest Milling for Beginners and I have to say it is excellent you couldn't have a clearer or more understandable "how to do" than that.

I hope.beginners are reading the guides I for one have picked up such a lot from them.

Well done Sir, great stuff.

Thread: My new lathe a Warco 918

Hi Ian,

Its a standard Digimatic with the 0.0005" steps on the last digit as Jason and Martin said.

Thread: Screwcutting on the lathe
17/11/2019 18:04:25

Iain, going by my experience with the mini lathe it does seem to me that something is amiss with your machine. I found some notes I made when practicing thread cutting and I had no problem with 60 rpm though I did most of it at 80 rpm but that was just me wanting to make sure I was a little more into the power band of the lathe. It would be interesting to see how you get on with the EN1A if you give it a try, hopefully it will be ok and the problem was just the B&Q material and not the machine.

Thanks Jason, thats good to know.

17/11/2019 15:59:05

I will be using the GT inserts primarily on aluminium, how do they perform on other materials..?

Thread: Screwcutting on the lathe
17/11/2019 11:18:53

Iain, as Jason says there must be a problem somewhere, my mini lathe was 500 watts (brushed) and I had no problem cutting threads with it of various sizes, I used low range which had plenty of torque at low speeds.

Thanks guys

Ketan, I am in no panic so will order some when they appear on your website in the next couple of weeks.

Would I be correct in that ARC only do the CCGT inserts in the Sumitomo range.?

Posted by Henry Brown on 16/11/2019 11:57:49: It's interesting that very few replies have said anything about the Chinese cheapies, but somebody must buy the em - perhaps to use as G clamps...

Henry, I will let you know I have ordered a Chinese one for a grand total of £7.00. A friend bought his for £6.00 and says it is fine and more than accurate enough. Will be interesting to see what turns up.

Thread: To pin, or not to pin

Posted by AlanW on 12/11/2019 16:29:23:

failure in this instance would risk irretrievably damaging the shaft that would be difficult for me to replicate

Alan, I would have thought that answers your question......pin it to be certain.

Alan I use 638 all the time and swear by it but going back to what you said in your original post (highlighted above) and based purely on that I can't see how "not to pin" is even a consideration just do it and remove any doubt.

Morning Jason

The picture of the type B main frame set up in the lathe looks interesting I am guessing the V and 123 blocks are balancing out the bulk offset in the casting. Is the V taped on with 123 cross wired over the top..?

Ron

One thing is for certain Jason, I dont think I would ever get tired of looking at those engines they are different to say the least. I can see that some of the parts may be a bit of a challenge to set up for machining but the end result makes it well worth it, the Type D I think looks amazing.

Can I ask you keep us up to speed with progress it will be good to see them come together.

Ron

p.s. Forgot to say that watching the videos both the Type D and SB2C run very nicely indeed.

No that's another one of his engine designs, a Type B

Jason, would I be correct in thinking you have a full set of castings for the engine and going by the picture did you bring them in from the US.

Thread: What Did You Do Today 2019
15/11/2019 05:53:45

It was yesterday actually we were in the town and passed the 3 mobile shop so as a long standing customer popped in to see if I could have a free upgrade to a new phone, no problem sir and after 20 minutes walked out with a new £400 phone. We had a coffee in M&S and as we were leaving and standing at the top of the stone stairs the wife asked to see the new phone she was admiring it when she dropped it and I watched it bounce down 12 steps to the bottom. It was wrecked the screen was smashed and wouldn't work, I went back to 3 but I hadn't taken out any cover so had to buy a pbone. I didn't spend £400 but they did me a good deal on another model which is still street's ahead of my old phone. The wife is still upset over it despite my telling her not to worry about it in fact the new one seems to be nicer to use and the camera is excellent so not all bad. 

I know I know it was a bit stupid handing the wife the phone at the top of the stairs
