In this video I show you how I made a straight edge without a reference device, using nothing more than a three lengths of mild steel a few hand tools and lots of time.
The straight edge is an instrument I need to help me check out the Vee ways on my south bend lathe how I do this will be on my next video.

"veritable JCB" ... does not compute.
@Thesheddweller
@Thesheddweller Год назад
‘JCB’ here and in quite a few places around the world is a tractor 🚜 with a shovel on the front and a digger on the back, for its size it is powerful and universal a sort of small CAT earth mover. In this case, to be a ‘veritable JCB’ implies to shove material off at a good rate

Hi Paul. Just found your channel via this video and I've subscribed. Very interesting method of making the straight edge. I need to work the bed on my 80 year old colchester master before long and found the price of a straight edge or regrind very prohibitive as you did. I'll be very interested on your approach to mapping the lathe bed and will follow this closely. My little workshop and channel is still evolving as I delve into machining as a hobby from a career in heavy engineering and maintenance. Finding people like yourself who can provide good content and concise descriptions of what you are doing is a must. Thanks for the video Cheers Neil
@Thesheddweller
@Thesheddweller 2 года назад
Hi, I wish you all the luck in the world with your new channel. Mapping the bed ways are going to be done and shown in a short video soon. For your information…. I don’t have any special camera equipment, I have… 1 Aldi motorcycle camera, 1 very cheap amazon video camera supported on a wooden d.i.y. tripod, 1 very low budget clip on mic dangling off some sellotape from a bamboo cane. . The whole lot cost about £73, so what I am saying is, let nothing deter you, then try improve on the previous video with what you’ve got, most important of all, listen to your subscribers and you’ll soon be finding the whole adventure a pleasure. regards.

Micrometer Brand Engineers Blue, I think it's the first time I've heard it mentioned on You Tube? I still have a tin of it I picked up about 40+ years ago. As soon as you look at it, it gets 'everywhere', the more you try and clean it up, the further it goes 😁 I very rarely need to use it and when I do, as you said, use some 3 in 1 to thin it out a little. I have mostly used a Sharpie/felt tip pen for general layout for as long as I can remember but Sharpie has a noticeable 'thickness' when used for checking mating surfaces plus dries out so doesn't transfer well

Sir, your work was very didactic for me. I´m trying to do something similar. Regarding the engineers blue, there are several tricks around, in my case, due to the lack of good suppliers in my area, I prepare mine using powder prussian blue into vaseline. it works fine for me. I could get flatness of 5 microns in 1.2 meters.
@Thesheddweller
@Thesheddweller Год назад
Sorry to appear so patronising but, I do try to aim for middle ground in my explanations. I have pointed out before that, I only show how I did what I did and hopefully I won’t be telling anyone how to do anything, because there are literally dozens of ways to do any engineering task, as with your powder and petroleum jelly to replace engineers blue. I do however, understand your supply issues. regards

Excellent video I will need to watch it over (a few times maybe) to understand six step process. I get your dilemma on the cost of professionally regrinding the bed. The solution is swapping professional cost with your labour (time) at home. If I were in the same situation I would offer the professionals off the books free labour around their factory/workshop for the regrinding job. At the cost of labour these days your time even with a healthy excess margin maybe comparable to the time spent at home doing the best you could. Enjoyment doing it yourself at home verse enjoying working in a modern workshop. It could be a win win solution?
@Thesheddweller
@Thesheddweller 2 года назад
Hi, thanks, thats a great idea. It might be worth a try if they have manual machines. However, they would probably work the same probationary process that the company I worked for used. As a charge hand, I knew that 'new employees' cost the company a lot of money until they had completed the probationary period. This includes huge amounts of time with health and safety, induction courses, fire drills, overalls, thats before the machine familiarity and assigning another operator to oversee ’the new guy’. this is because of the size and cost of machines and the cost of materials is so high. Oooo… I just found myself reading the riot act again .. I think I’ll just do it myself. regards

I think I'd have been tempted to machine at least one of the straight edges into a sort of a flat topped inverted V so as to get around the problem of windage. I've seen a video of this normalizing process before. Yours is way better. That other fella used abrasives. Did you look into the cost to have the edge ground to some stated tolerance?
@Thesheddweller
@Thesheddweller 2 года назад
Hi Raul. No, i didn’t look into the cost of getting the edges straightened because, the cost of getting stuff done here in the UK is prohibitively expensive. For instance getting a tooth refitted to the back gear wheel is in excess of £500, then I’ve got to re-profile it afterwards. I’ve used these straight edges quite a lot lately and they still confirm true against each other. After Ive finished the lathe I’ll probably use the material from these straight edges on some project. regards.
