Welcome aboard!
Steve sent me - just starting my scraping journey - glad he sent me your way
welcome to the channel - lots to view on the scraping front. I am no expert, bu I get by and with patience achieve a degree of accuracy. All the best Mat
Many thanks for posting these , I was shown how to do some basic scraping 30 years ago but after watching both of your videos there was obviously a lot I wasn't shown .
I am glad it has helped. There are plenty more videos on my channel and I do where I remember give links to other good scraping videos. All the best Mat
Steve Summers suggested a visit. Very impressed with your work on the gear box. Then I watched some of the scraping. Awe inspiring !

Hi Jim, thanks for the comments - there is a good back catalogue of videos for the Holbrook lathe and the shaper rebuild - well done on the questions - now pop up to the links in the channel home page to make a channel contribution of $5 for your name to go in the hat - $20 gets 5 tickets. Good luck and all the best. mat
You've come a long way since your earlier scraping videos Mat. Your mentor Chris? I think would be quite proud of that job. It's beautiful and I'd be impressed if I could do half as well. Maybe someday. I still can't figure out why both yourself and Jan don't have a hell of a lot more subscribers than you do.
Thanks, I feel my skill set has developed a good amount with the Holbrook project. As for subs' - I have spent a lot of hours pondering the same. Maybe its just a UK thing -there must be thousands of model engineers and steam enthusiasts yet limited numbers of machinests that watch YT ? There are a few popular UK cannels where they have 20K + , but very few over 50k. Compare that with the US based creators - most have passed 5k within 2 years. Ive just reached 3k after 5 years. Still keep plugging away at it though ;-)
@@lookcreations Hi first time caller long term viewer and sometime machineist. Due to injury I am now an armchair warior.
Your skill is self evident.
I wonder if you suffer from not preaching the orthodox wisdom "there is only one hand scraping method and that's Moore pattern". To my mind Moore patern is for machine ways and designed to achieve a high point count with comparitively deep oil pockets at the same time.
Your and chris's "scrape for flatness first" is obviously the right way to go for reference surfaces as it creates a much more uniform surface for printing.
I am sorry to hear that chris has passed listening to him talk in your early scraping videos was an education.
@@elanman608 Thanks for stopping by. I am in no position to preach - others out there have the louder more angry voice - a few exceptions in the likes of Robin Renzetti and Tom Lipton on TH-cam who already have the respect of machinests - To my mind you see very little in the form of 'Curling'. 'Moore Pattern' being a form of that style. I barely 'scratched the surface' with Chris and his knowledge - it is a huge loss of wisdom and experience - the hours I spent with him did allow me to soak up most of what he delivered - keeping him on subject was the problme ! I take the view that while there are many styles of scraping out there, the principle is the same, though quite a few 'trained folk' seam to have missed the basics of alignment, bearing. oil retention (where necessary).
I leave you with one comment Chris said repeatedly to me as I wrestled to control a the scraper and produce an acceptable curl to his eye - "I nead to get you out on a job with a few 'big shears' somethingwith 14" wide x 30' long. Start you off at one end - by the time you get to the other you'd be fine or have left hours before, lost a few half desent lads over the years to that trial.... but it does sort out the ones that will make it in the trade."
@@lookcreations Sorry "preach" was a poor choice of words I was trying to say exactly what you have just said, there are a lot of voices both on channels and in the comments columns which maintain there is only one recieved wisdom. The truth being that there are always multiple ways to achive the same end.
I personally prefer to watch content like yours where you present the process of learning a skill both the reaserch and lessons learned. Then the inteligent apication of that skill and the reasoning behind the decisions you make.
Finaly thank you for preserving some of Chris's wisdom in your videos many old hands in so many trades are passing without being able to pass on their knowledge.
Good luck with the channel and I hope subscriptions pick up

Hi Mat. I very much enjoy your channel and have found it very helpful as an introduction to scraping, particularly these two videos on this straight edge. I subscribed last year and look for each new video as I find them consistently informative and entertaining. I sent the channel a donation; please enter me in the draw for the straight edge. The answers to the questions are: blue; Holbrook;
Hi Gavin, I received your donation, and will put your tickets in the hat for the draw. Thank you very much for your support it is really appreciated. All the best mat
How do you maintain the 45 ° angle ?
I don’t. The included angle is not important, only that the faces are flat and that the inclined face can access a 50 degree internal dovetail. Have a look at one of my dovetail scraping videos on the holbrook cross slide. You can see how it’s used.

If I can recover the costs it would be a start Craig. Thanks for watching Mat
Damn!just finished the watching both episodes I’m a beginner and this was the best explanation of hand scraping I’ve seen. Thank you sir!
Glad you enjoyed it. Take your time when you start out, learn to get a repeatable scrape before trying to dig deep or get fancy patterns. A shallow consistent pass will progress you quicker than a patchy deeper pass which creates problems down the line.

Nice to see you here from Instagram. All the best Mat
I've been thinking on possible options for making some sort of reference plate for layout, maybe even for attempting some scraping. I just remembered that I have some counterweights from an old skid steer, laying out in the horse weeds somewhere. Time to liberally apply bug juice and go hunting, to see if there is a chance of them working. Between you and The Cogwheel, the chiggers, ticks and snakes will get me yet 🙂
Cant hurt to find them - maybe with a long stick first though :-)
@@lookcreations not where I thought they were. It's been long enough since the time I parted the machine and paid any regard to them ... I hope they didn't grow legs.
Steve Summers sent me over to your channel. I’m wondering where have you been all my.life I love it
Great stuff, thanks for the comment - hope to see you in the ocmments section as we progress. All the best Mat
Enjoyed your scraping video. Wow Really looks great your very talented. I love looking at new scaped surfaces. Something i would love to learn.. Just bought a Harrison L13. That im hoping to refurbish. But scraping to me looks so daunting besides the lack of precision tools. 👍👍👍
Hi Mark. The tooling isnt so sophisticated as it first appears. If you can use a dti in 0.001" its not a huge step to go to half that 0.0005" and for the vast majorty of scraping work thats accurate enough after that its looking at blue splodges ;-) Keep in touch - Ive a few more videos to put together as I complete my tool room lathe rebuild - much of it will be applicable to most lathes. All the best Mat
@@lookcreations thanks mat I'm looking forward to seeing your content and upcoming videos..
I would love to learn scraping. But all the necessary tool outlay would no doubt cost a few hundred if thousands. For my bed ways. Unless there's a simpler option. I will definitely enjoy your lathe rebuilds all the best mate. Mark
@@markgrevatt4867 The most costly bit of kit to start with is the original master you use - usually a Surface Plate. Granites are anywhere between $50 & 800 depending on size and condition. I started with a 20x18 which was £270 and a new stone . Everything else I use has either been made or bought used and re-conditioned as I learned - even the dti's (which I sent to be serviced at £10 each. Plenty of guys have had success with heavy duty I beam / columns to make a straight edge for say 6' - steel is harder to work can be more unstable but far less pricey than a casting or for that matter a used 6ft straight edge. Besides a 3ft SE would work fine on a lathe of say 8ft bed or even 10ft with some care and a spirit level. Having said all the above - you can spend thousands and many guys do. Im tight so try and avoid expenses :-) All the best Mat
The odds of winning the Straight Edge are looking pretty good - 6 entries so far (32 tickets total) - remember yo uhave to make a channel contribution & answer the questions. details in the vid and info below the vid. Good luck folks. mat
A brilliant couple of videos here Mat - loving the laid back style! +1 sub 👍
Much appreciated. There’s a few hours of scraping videos taking you through my journey getting Straight Edges faced for rebuilding a shaper and a tool room lathe. I’m no expert but I’m happy to share the knowledge learned. All the best
Mat
@@lookcreations thanks I will have a watch. Contacted Iron Clive yesterday about getting a straight edge, unfortunately he doesn't do the 12" ones any more as they worked out the same cost as the 18" ones. 18" is too big for my surface plate so will have to put a straight edge on hold until I get a grown up plate. Cheers!
@@radboogie in a couple of my videos you can see how to scrape a straight edge longer than the surface plate. It’s not as easy but straightforward enough with the right mindset. 18” is far more useful than 12” unless you’re working a short slide, even then 18” works fine on 12” slide.
wow
Thanks for stopping by. Mat
Thank you very much.
You are welcome!

Glad to welcome you to the channel & thank you for your entry. Ive put your name in the hat 5 times ! Good luck. Mat
steve say no more.
Welcome to the channel, hope you find the content interesting and entertaining
did you mention how to reference the bevel to the base? or maybe that comes later in the video. I did FF in a few spots and might have missed that
If by reference you mean set the angle, it is not a critical angle. As long as it is less than the one being printed it works. If you take a look at some of my other videos scraping dovetails you will see the inclined face is scraped separate to the flat. The mating face is then scraped to it and thus angle is matched
@@lookcreations I see. Thank you. So it won't be a reference angle ....... but merely a way to get a flat plane into a dovetail for example. By the way the final product looked really great. Just how hard would it be for a noob with reasonable patients and intelligence to make a flat plane over 12"?
@@dizzolve if you have a surface plate as a reference to start with, it’s an exercise in learning from the experience. So if you had a good reference plate and wanted to create a straight edge say the length of corner to corner off the plate. You start and take small steps check each cycle to see how things improve (repeat more of the same) or get worse (investigate and determine what you did wrong). Patience is useful but consistent approach gets you progress- consistently wrong means you just have to keep changing one thing until something improves. A flat plane is the starting point, after that everything then is based on consistent measurements and assessment.
It’s not complicated, hand work is hard work. The bigger the item the harder the logistics (printing etc). As a simple exercise to create a flat plane the scraping might take a couple of days. But you also have to learn how to get a good consistent print, sharpen the carbide tip and read a print. So add in your errors and repeat the work a few times- call it a week 😃
1- Blue, 2- Holbrook, 3- 40 hours. Also, good job on the scraping! Would love the straight edge and put it to good use :)

Good to see you commenting - thanks for the channel support and good luck with the competition.
Blue, holbrook, 40hrs.
Bloody good videos mate I really appreciate your approach to it. I've just got my surface plate and looking for a scraper and straight edge next. Couple months of recovery after back surgery then I hope to be able to scrape my colchester ways one day. Very keen to get into it and really appreciate the effort you put into this! Heading over to patron now.
Thank you James, any problems with the Patreon let me know - or use the donate function for paypal on my channel page. Good luck Mat

Hi Matt, love your no nonsense plain talking approach to your video’s, very inspiring.looking forward to seeing the Holbrook in action . Answers to questions 1. Blue 2.Holbrook 3. 40hrs . Be great to see the clarkson in action or D bit grinder if you get one . Just amazed to see what you achieve in the space you have. Best regards,Brian skidmore.
Hi Brian, thanks for your entry to the Safe Edge Competition - thanks again for your positive comments - as for my 'plain talking approach' I tend to think its a part of the culture from where I am from and the area I now live. Never been one for dressing things up 'a spades a spade' works for me. Once I get the Holbrook up and running, I will have to decide on what next - get shot of the wood working machines and make some space then bring in the T&C grinder and make a decission on it - either tool it up or get shot and downsize to D bit grinder. Meanwhie, there is aTIG welder sitting waiting to be used and Ive an ever increasing list of jobs for it once I can learn how to use it. All the best & good luck with your entry. mat
I've worked at a couple fabrication shops where quality control was like that. Just keep taking measurements until you get one you like.
Its more common than you think ! Thanks for stopping by an dcommenting.
Mat, did you consider purchasing a Biax type electric scraper as used by Kieth Rucker ? 👍👍🏴
I have one. At some stage, I will make up some tooling for it and have a play. To be honest, I don’t find it enjoyable to use, noise, vibration and then the weight. Maybe on a big surface plate . Time will tell. Thanks for stopping by , all the best Mat
Steve also recommended I view your site, I'm glad because I have always wanted to learn to scrape my Southbend 10K lathe ways.
Hi, I hope that you take the time to watch some of my content - Im no expert but I do alright. Plenty of scraping content as Ive rebuilt the shaper and best part completed my tool room lathe. All the best Mat
I'm a new sub, Steve Summers sent me. Great video !
Hi David, - thanks for the sub' - enjoy the channel and the journey. All the best Mat
I want to have a go at scraping a surface to flat. where do you buy the tools from?
Majority of my tools come from EBay. I made the scraper and fitted a standard sandvic carbide bit. The surface plate was eBay new old stock. My larger granite plate was new Chinese import. It checks out well inside tolerance.
@@lookcreations I shall have a scout about on ebay. There are other auction sites I use for industrial stuff that are worth a qucik scan over too. Thanks for the prompt reply young man!
@@JonDingle if you get stuck - shout. I might look at making some scrapers in a range of sizes to suit different jobs and users. - if you are spending money - buy the best surface plate you can afford - a big one in por condition will require a lot of work to get it right, a small one in good condition may cost around the same but its good to go - the problem is smaller plates are limiting in their use. So think about the kind of sized work you want to try. A cast iron SP you can scrape flat with a level and SE - your SE needs to be good though - chicken and egg there ! A granite plate has to be lapped and thats not simple without more kit and measuring gear. Good luck. Mat
@@lookcreations Cheers taa for the info and such like. I will trawl Bidspotter because it can be a good source (you may know this already?) as and when suitable sales come up. Top regards, Jon.

Hi Randall, thanks for the subscription - I hope you take a look through the videos uploaded and stick with us for the journey. All the best Mat
Hi, so it came to you milled to 90,and 45? so does it not alter the degrees?
The actual angle of the bevel is not critical in use. It just has to be smaller than the angle of the dovetail way. You only prnt a single face at a time when working. Only on rare occassions to do you use a 'form' master - that gets a lot more complicated to scrape and use. There are afew examples of my using a dovetail straight edge on earlier videos and I shall be using one on an up comming vid in a couple of weeks.
Thanks for stopping by, Mat
@@lookcreations Hi, I would like to try that some day. Thanks
