|Thread: Think you have trouble losing your chuck key?|
Impressive work. Inventive use of the pantograph too, I like it!
Very nice indeed, would also be interested in the finer details. I like how the jaws are to scale also because that is my problem with the ones made for the kits like David's, they are always too big (no disrespect David, your model looks great) but the makers (Stuart and others) must deem it too fiddly to do the jaws to scale?
|Thread: Er32 3mt Collet Holder|
I wondered the same when I first got mine but it is there to retain the collect, the collet snaps into this offset ring and it holds it there.
Good pictures and description here: https://www.arceurotrade.co.uk/Catalogue/Collets/ER-Collets/ER32-Collets
Edit: Jason beat me to it

|Thread: Heinrici without Castings|
Top work on the finishing there you really have aged it nicely. If you would have said it was an original engine I wouldn't even bat an eyelid
|Thread: Digital Callipers - again|
What Emgee said. I have 3 pairs, all purchased second hand and all bullet proof
|Thread: 1/20th Scale Traction Engine|
Starting to take shape now, really looks the part 👍
|Thread: Making mild steel look like cast iron|
Thanks all for the tips. I do know someone who does some agricultural sandblasting which might work to blend everything in and give it a bit of texture but that would obviously leave it a light grey.
I had thought of going down the route of submerging them in brine to let them go rusty in order to give them a bit of texture and then treat them to remove the rust. I do believe I have used a rust treatment before that turned the steel black as Neil described.
I do have a needle descaler which i might try out also for some texture.
Finally I could try polishing them with Zebrite and see how that comes out.
Thanks all for the ideas
Far from model making but im sure some knowledgeable people on here could advise. Long story short, I have restored a couple of these fireplaces for my house and unfortunately the mantel shelves have been lost to the sands of time and I would like to fabricate some out of mild steel. No problem there however the fireplaces are the bare, raw cast iron dark grey colour/finish and I would like to try and match this for the mantels if possible.
They will obviously be manufactured from mild steel, welded and ground/dressed etc. Just wondered if anyone could offer any advice on how to make them look like an original cast item. Painting is the last resort really, but will paint the mantels if necessary.
|Thread: Baby bullet vice|
Very nice job on the vice! I thoroughly enjoy Tom's channel and have also downloaded the vice plans with a hope to build one some day
|Thread: Thompson Engine from Scratch|
Beautiful looking engine! Look forward to a video of it running
|Thread: Digital Height Gauge Recommendations?|
I would also recommend a vernier/dial version over digital. I have a less expensive, but by no means cheap, digital height gauge and it drains the battery when not in use, which is irritating if I forget to remove it. As above I have since bought a second hand vernier mitutoyo, a joy to use.
|Thread: Tap and Die Puzzle|
I dipped into my M4 box to tap a hole one day and found that the screw didn't fit the thread, on closer inspection the tap was an M4 x 0.75, quite irritating
|Thread: Milling Machine Identification|
I would suggest that that machine could be 3 phase assuming it is being powered by the 3 phase red socket and plug on the wall behind. Also the 370 380 numbers you mention could be voltage ratings but they could equally be wattages. Hard to say for certain without further examination but dont assume its single phase
Hope that helps, Craig
|Thread: 1/20th Scale Traction Engine|
Nice looking model coming together here 👍
|Thread: Looking for foundry in Bolton area|
JW Longbottom just outside Huddersfield is one I am aware of. They specialise in rainwater and soil items but I have looked through their catalogue and they do a wide variety of items and also do one offs apparently. I have never used them, an eye watering quote was as far as I got, but might be useful for others, as has been mentioned there aren't many left doing this sort of work
|Thread: Power Hacksaw|
I suspect Paul's saw is a Femi but rebadged. I have the same saw badged up as Clarke, originally sold in Machine Mart. I purchased it second hand and I first thought it was probably a knock off of a Femi but the original sale sticker price was still on it of over £300.
The saw is very compact but very capable
|Thread: Another, What is it ?|
Hi Peter, PM sent.
|Thread: Boxford Lathe Dismantling|
As mentioned above the whole lot can be lifted as one with an engine hoist or similar using the lifting holes in the cabinet. When I collected mine I didn't have a hoist so seperated the lathe from the cabinet (you have to disconnect some limit switches, uncouple the linked drive belt and undo the bolts) then 2 of us lifted the lathe into my van and slid the cabinet up some ramps and into the back
Hope that helps
|Thread: VFD/Lathe fault|
Your initial problem is almost as if your minimum speed/frequency parameter has changed from 0 to 34.6, or like you say your pot has gone duff (their functionality can be tested with a multimeter).
For you to have now lost your remote controls it could be that some parameters have changed. If you could post a picture of the parameter information you have then it may help to pin point which ones may need checking.
As an aside, we lost all parameters on a drive at work once and the only backup we had was an old print out. We had to go through all 999 parameters changing what ever needed changing.
Let's hope your issue is a much more simple fix
|Thread: Tramming Milling Machine|
That's how I did mine, by loosening the post from the base and sliding shims in left or right, front or back. It's also how it was done from the factory as I found small shims in there when I first did mine. Its quite a long winded process doing it this way but as far as I'm aware your only real option. I have only done it once but to be fair it's not bang on and could use an adjustment.
Hope that helps, Craig
