|Thread: Portable vice - buying advice sought|
+1 for the Record Imp's
I have a larger 4½" one on a swivel base, and a couple of the smaller approx 2½" ones.
One of the smaller ones has its serrated jaws still, and the other one has some smooth steel jaws.
|Thread: Eueka! - Has music been redefined?|
Nice job on the Eureka by the way.
According to Google Translator
|Thread: Press fit sizing|
Oilite bushes are designed to fit a H7 tolerance reamed hole. There are various standards available but the H7 is the most common.
|Thread: Material for coupling rods|
Or if you have an open hearth fire in your living room, you can chuck a few lengths of BDMS in before you go to bed and then leave it to cool slowly overnight and it should be nicely stress relieved in the morning.
Myself and the wfe have now both had two AZ jabs which were five weeks apart.
I had no after effects whatsoever, but the first one put my wife's heart into AF for a couple of days which was frightening as she had an operation to cure the AF a couple of years ago and was worried it might not go away again.
It went back to normal after about 48 hours, on the second dose she just felt a few flu like symptoms for about half a day.
We were lucky to get our second jab a bit earlier, she rang the doctor about something unrelated and just mentioned about a second jab and they booked us in for the following week with no bother at all.
Actually thinking about it I went very sleepy when sitting watching telly, but I blamed the Gin for that

|Thread: All the gear, no idea|
Do you know if there is model engineering club nearby, if there is then one of the members may be able to call and advise you.
|Thread: Milling machines - western-made s/h recommendations up to Ł2k|
If that Centec 2B advert above is genuine and not an April Fools joke, then £650 sounds to be a real bargain.
|Thread: Steel Rule Graduations Re-Blacking|
I use a black "Sharpie" pen, and rub the unwanted overspill away with a fine garryflex block.
|Thread: Home made screws|
You were correct, the blank size was the problem.
It also gave me a chance to try out the ultra slow speed inverter setting I rigged up on my Pultra 1770, I can run a thread up to a shoulder under power and then reverse it off again, I am really pleased with the results.
Thanks for giving me the advice to carry on, I had all but given up on the roller box but it works very well.
Yes I did get the test piece with each one, and it does screw in easily, I actually measured the remaining bit of plain section on it to find the blank diameter and it seemed to be 1.4 mm so that is what I tested it at.
I will have another play and see if 1.35 mm works out any better, I could not see how it would work with the rollers revolving as they are not retained on the shafts, so it has to be down to the blank diameter I suppose.
Do you use any lubricant on it when forming the thread ?
PS, Just so others know what we are on about, here is a link to one.

I have just been experimenting with those thread rolling dies with very little success.
Do you know if the three "rollers are meant to revolve or do they just form a thread as they push forward, mine do not revolve and the friction is just too great for the material to hold up against the twisting force.
I am making longer studs rather than headed screws.
Any advice would be welcome.
|Thread: Multi-dimensioned Drawings|
That looks to be very bad practice to me, very confusing and open to mistakes.
Normally you would assign each dimension a letter, and then tabulate them in a chart on the drawing for each alternative size.
|Thread: gun with trigger for bead blasting cabinet|
You are spot on with your comments regarding air to the pickup.
The operation of the gun relies on the fact that a vacuum is generated in the gun body and it is that vacuum which draws media up the hose and entrains it out through the nozzle.
At the point where a Guyson pickup fits, it can be adjusted in and out of a mixer box which sets the mixture to the correct ratio, it will need re-adjusting if the media type changes significantly. glass bead performs very differently to say a steel shot or other heavy media.
I am afraid there is no substitute for more air capacity, most blast guns will only give mediocre results if you are trying to use a small compressor that cannot keep up with it.
The comment about the Guyson 400 not being any good is a bit unfair, that gun performs extremely well if it is set up correctly and has an appropriate air supply. The design goes back many decades and despite many attempts to come up with a better design over the years, it still remains one of the core products for Guyson's. In fact many people buy a Guyson gun to upgrade other makes of blast cabinet.
|Thread: Honda 125 electrics|
I run a 1972 Honda XL250, the electrics are very marginal on that as well, the bike runs perfectly until the headlamp is on then it starts to misfire at high revs.
I never got to the bottom of it and dont understand why it should do that as the lighting and ignition coils are separate units and should not affect each other.
I tried an LED bulb in my headlamp, but the rectifier must be not giving a very clean DC output and the LED lasted a matter of minutes.
I solved the problem by never going out in the dark on mine
I am with the others on this, run the engine and see how it performs before you change anything else.

|Thread: A new job|
I dont know why, but when you said Vroom Vroom Vroom, I immediately thought of our vacuum cleaner
|Thread: Finish for wooden base|
Has anyone tried Sikkens Cetol Filter 7 Plus on model engine woodwork yet.
My Morris traveller wood is finished with it and it is excellent stuff, it allows the wood to breathe without any flaking off like you get with normal varnish, it also leaves a dry surface that does not attract dust as Danish oil can be prone to.
|Thread: 5 BA Cap screws|
Could you use slotted cheese head screws instead ?
EKP do them
Dont know about 5BA, but could you use M3 instead they will be pretty close and readily available.
