Thread: Product Descriptions (Up to scratch?)
19/01/2020 08:17:17

Having had a mini lathe I think a couple of points worth considering is to go for one with a 100mm chuck, 400mm between centres and a 500 watt motor (ideally brushless direct drive)

If I was buying one now it is what I would aim for.

Thread: Has anyone watched this Girl
18/01/2020 09:34:07

Very impressed, she has a pleasant voice, speaks clearly and is obviously very skilled and a good teacher. Much better than a lot of teaching videos I have watched and excellent for the beginner. I have watched 2 or 3 of her videos and picked up some good tips and some good tool projects, will have to watch some more.

yes

That's impressive Andrew especially with it in 3mm steel and having shallow flanges, can't have been that easy to do.

Looks very good.

I read yesterday that the production of the original MAPP gas ceased in 2008.

Having spent quite a while on Frday evening and even more on Saturday flicking teh RMC type A flywheel round I came to the conclusion that it is not going to work on propane instead of the now unobtainable MAPP gas I drew out a new head for it last night so it can be built as a 4-stroke, did the CAM this morning and then after lunch got the Sieg KX3 to spit out the new head in just over an hour. Still needs some holes here and there but will do those on the lathe and manual mill and then give it a lick with the needle files to get rid of the contour lines..

 

The bonus of CNC Jason that would have been a lot of work on a manual. What is the make up of MAPP that makes it different to propane and why no longer available..?

Thread: Mini lathe amadeal cj18a help needed
14/01/2020 16:05:33

Neil, unfortunately I dont have an answer to your problem other than to suggest you check the drive train from motor through to the chuck. It sounds as if the work you were doing at the time you lost drive was light duty and assuming there are no faults within the drive assy its strange that the motor drive pulley has failed yet again, it could be a faulty pulley of course but I wonder..? Have you checked the motor pulley to see if that is where the problem is..?

When I had my CJ18 I stalled it twice whilst parting off and the second stall broke the plastic high/low spindle drive gears inside the head. It was quite some force as it broke off some teeth and split the main body of the gears and yet the small plastic motor drive pulley was fine including the moulded in key.

Have a good look at the motor pulley and the rest of the drive to see if you can identify any problems which could cause the motor pulley to fail (if it has of course) it could be that the problem is elsewhere.

Thread: Class 22 Diesel (next project)

I took a gamble and bought a cheap Chinese set of 4 radius edge cutters, cost £8 for the set 1/8, 1/4, 3/8 and 1/2 inch rads.

The 20mm thick loco body cab/end plates have radiused edges which I was planning to cut and shape by hand but then thought it better and more accurate if I could machine to the basic shape and then hand finish. I didnt want anything expensive as the cutters will be seldom used if at all.

I know router cutters are run at high speed and I only have a top speed on the mill of 2500 so that was the main worry, would they work at the lower speed..? Need not have worried as they work and cut just fine, tried some test cuts on a piece of Pine, unknown hardwood and MDF and they left a very clean finish even on the MDF which surprised me. So in this instance £8 well spent.

Thread: RMC Type-B Engine Build

Very nice, I am ok with the paint job, quite like it in fact makes a change from reds, greens and the like.I can only go by the pictures but I wouldnt say it looks lifeless in fact quite the opposite it has areas of reflected light and highlights, looks a very clean finish, well to me at least.

14/01/2020 08:23:17

Nice work Jason, interesting, I picked up on the hand turning have never tried that will have to give it a go. I am guessing that the tool support bar is fixed to the tool post. The oil channel built into the nameplate is a neat idea I like that.

Thread: What Vice should I buy (2019)
12/01/2020 10:24:52

I have a 80mm ARC versatile which I am really pleased with, great value for money. I have the swivel base removed but I have used it a couple of times. You certainly need to consider the size of vice, surprising how big a lump they are relative to the jaw size.

Thread: Australian Bush Fires
12/01/2020 05:45:24

I am not upset just a bit of over reaction on my part I guess. I watched quite a bit of footage on the current situation yesterday and it is tragic beyond words just heartbreaking. Sorry Neil I didn't appreciate the humour at that time.

I am surprised at you Neil, with you a chartered environmentalist and qualified ecologist I think the above is in bad taste and not funny at all if that is what its meant to be.

Climate change has little to do with the fires as they are part of the natural cycle of things here in Australia .

Backburning is unpopular with most interests, not just tree-huggers; the problem is that 'saving wildlife and habitats' gets used as an excuse as it's convenient for many different interests.

I posted this on the ‘What did you do ... 2020’ thread, but I think it worth repeating:

Yes it is a wonderful series Michael but now tinged with a feeling of "how it use to be" as a lot of what you see in the programmes will now be gone and some gone forever. I heard a news report today which said that of the millions of animals which have perished in the fires there will be some species which will in the long term never recover and face extinction.

Jason, I know it says so in the Preston video but the flywheel rim is a piece cut from a 7 inch diameter steel tube am I understanding that correctly, if so it must have been quite a thick walled tube..?

Thanks Mark, information appreciated.

We have a couple of local firms which make bespoke kitchens so I will pop in and see what material they carry and if suitable if I can purchase some.

Thread: Really basic lubrication question?
06/01/2020 05:01:56

I read somewhere that motor engine oils are not recommended for use in or on machine tools because of some of the additives can cause damage. Unfortunately it didnt explain how or what damage and of course you have to ask is it true, I don't know...?

Thread: Choice between cheap mini milling machines.
05/01/2020 10:08:47
Posted by Derek Greenhalgh on 05/01/2020 09:24:48:

Bare in mind limiting to £500 for a mill, remember you will still need tooling, some form of holding your part be it a vice or clamp system, cutters etc. you can eat up the 500 on those alone without even trying, Last year i bought an HBM bf28 vario, almost identical to the PM25mv and Warco have the same machine, cannot remember the exact number but since then i have spent well over £1000 on DRO, rotary table, vice, collet chuck and collets and a few basic cutters. I already had DTI, micrometer, calipers etc. from having a lathe.

I was told the cost of the mill is the cheapest bit and would probably end up doubling the cost of the mill on kitting up, I'm not far away and still do not have all i need/want. Something to take into consideration.

Derek

A good point Derek which is easy to overlook when you start out.

Just over a year ago I bought my SX2P mill second hand (12 months old) for £500 and since then I have spent at least £750 on tooling and mods.

Ok, I have done it bit by bit as and when I can afford it and let the jobs I have done on the mill dictate what I need, I havnt bought much just for the sake of having it but it is surprising how the cost of tooling soon adds up.

Thanks Jason that's helpful.

We all know MDF but is anyone familiar with HDF.

Apparently HDF is denser and stronger than MDF, hardboard is a HDF and available in 8ft x 4ft x 1/8" thick. I have read that HDF is produced in a range of thickness but apart from the 1/8" the other sizes don't seem to be stocked in the UK ?

Wondered if anyone knows anything of it.

Well 10 out of 10 for the improvements Jason it seems to be running strongly now and it kept running also. It does look good on the trolley/carriage better than sitting on the bench I think.

Three engines running in just a few days, cant complain at that.
