Thread: my first lathe.
12/12/2019 08:16:50

Made for a tangental tool I think. No idea why you would bother though.

Thread: 3D printer recommendations
08/12/2019 10:19:44

Call me old fashioned but if I have to take a soldering iron to repair a brand new machine im guessing there will be lots more unforseen issues and it would be going straight back to the seller for a refund!

Thread: Breaking bandsaw blades
02/12/2019 18:43:30

Chap who makes blades once told me, if it breaks on the weld then its a badly made blade - avoid! Ive been down the braze them back together but unless your desperate its just not worth the effort. I used the cheap Silverline ones off ebay with varying success. Then I bought one from a local shop....had it years...its a lot thicker than my previous ones and the box said Cobalt tipped (anyone know how this is even possible?). Anyway, vutting up to 1/4" brass and copper with only SIX tpi I ddnt expect it to hold out for long - best blade I ever used by a mile. Still using it! Even kept box somewhere so I gan try to source another.

for sheer out the box plug and play you cant get much better than the Flashforge Finder - incudes slicing and gmail software. Easy to design basic stuff in Tinkercad. Limited only by a bed of 140 x 140 but ideal entry level, very well built and under £200.

Thread: Looking for 7/64 mild steel bar
21/11/2019 14:37:10

Howard I think you may be correct - I hate turning long thin parts, never turns out well!

21/11/2019 11:26:18

2.8mm or 12 SWG would do the job. Its to hold together 3d printed tank tracks at 1/8 scale. Stainless would be good but as mild steel is easier for me to work with thats what I need. I use EKP as a supplier to PSB but never gave them a thought - will take a look. Thanks.

Hi - anyone know where I can get some - tried all the usual places but they only have piano wire or silver steel, but I need mild steel? Thanks

Thread: Aluminium welding
16/11/2019 12:07:00

my experience was that the material is such low grade that it was impossible to weld with tig, i tried to weld to lugs on the outside of my heli rc engine. Ended up buying a new casing!

Thread: First foray into 3D printing
16/11/2019 12:02:38

Collet holders came out great....so did allen key shelf, Die rack x 4off, cutter racks and chuck key shelf. At last a convienient place for pretty much everything. I have moved on to building a 1/6 th scale remote control tank - to my design and just for fun. Done tracks, wheels and suspension items and just designed commanders hatch - not printed yet as waiting for 10 reels of PLA to arrive. clipboard01.jpg

Thread: Miitutoyo caliper error
08/11/2019 18:50:22

Ive got a few of their calipers and Mic's but they do sometimes go wrong. Ive got a fairly new digimatic which has never worked correctly...should have sent it back but never got round to it. Will strip it and service it one day....might fix things.

Thread: Cast iron welding electrodes
29/10/2019 09:15:47

I strongly advise drilling a hole either end of the crack, seems to help stop it cracking more when you weld it. You didnt say if your rods had been pre-heated, im guessing not, and therein lies your problem. They need to be hot.

Thread: VPN?
17/10/2019 01:02:02

when i was on the road i had to use a vpn, now i work from home and have good security i dont really need it as i dont remotely access my server.

Thread: Curve Cut Problem
14/10/2019 19:39:45

Hi. Im using Curve Cut to process a 2d drill sequence. Problem is no matter what inputs I use I cant get away from "will result in more than 20 passes". Its a simple drill, retract move and repeat. Any idea what im doing wrong?

Thread: Would you buy one of these collets?
12/10/2019 15:57:31

At not more than £10 from most well known UK suppliers why would you?

Thread: Question from a customer
06/10/2019 15:22:29

The way I thought about it is....if the boiler were just a strong sealed container (which it effectively is) with water in it and heat applied, the water would turn to steam, the pressure would go up. Let it cool down and the pressure comes down to exactly where it was when you started. Nothing can have changed. The only difference when using it for real is that there will be less water in it when it cools down, assuming no more has been added. Ive tested this with a smaller boiler with no clack, running the water level down whilst maintaing 40 psi driving a D10. Closing the steam valve and after cooling there is absolutely no negative pressure that I can detect.

06/10/2019 13:04:33

anyone?

06/10/2019 10:13:01

A customer of mine has the set up below, two 5" boilers set up running a Victoria powering a dynamo. He asks: as the boilers cool they suck in water via the clacks - if there were no clacks could they implode? Now we know they dont, and blowing down isnt mandatory so how much negative pressure is there? I have never experienced this but its worth asking you folks. img_20191006_090424.jpg

Thread: Has to be seen to be believed
06/10/2019 00:42:07

And therin lies my unmentioned dilema. As a professional boiler maker I see how terrible this item is - If put under pressure it will simply distort and eventually fail - it wont explode, its not a bomb and it probably will fail at 15 psi....but its a terrible thing that is being passed off as well made. Do we have a duty of care to point this out or do we say nothing in the hope that nothing bad comes of it?

What is the significance of his statement he volunteers at Hollycombe Steam Collection?

This qualifies him as an expert in all things steamy
