Dear GOSSQ1 R5 R5 Mate what can I say. Fantastic video. Just bought same lathe to do up and use. Exactly same problem with Feed selector lever and perished rubber gator. How much I thought from Mr Harrison. I check out U Tube. Problem solved, steering arm gator fitted two days later. Thanks so much for the info, keep it coming. Cheers Les
Hello Les good to hear I have helped someone else with their lathe, I have used mine so much now I would not be without it. Good luck with your Harrison cheers.
Hi Nigel,been watching your videos of the Harrison M 300 refurb,I have been asked to see if I can build back up the feed gearbox,they have purchased a full set of cams and a couple of gears of which teeth where broken.Was hoping u could put me in the picture as to the set up of the plastic cams relative to the square part of shaft.Thankyou very much. Barry
Hello Barry I think I still have the correct sequence that was sent to me by a chap at Harrison Lathes when I did mine I will try and find it for you and post it here. good luck with the rebuild cheers Nigel
Thanks for the videom. i have recently acquired an M300. I have the same problem with the leaking seal on the feed engage lever. What was the exactly was the rack gaiter you used, please. Regards Jeff
Hello Jeff I just got a standard universal steering gator and cut off the small end of one gator it works brilliant and never had a problem with it. good luck Nigel
Great Video. I have a Harrison 15" lathe that has a broken gear that drives the carriage feed mechanism. You seem to know your way around these machines. I have hit a road block when trying to gain access to this gear and was wondering if I could send you some photos and maybe get some insight into how to proceed.
Hi Thomas I will be only to happy to help if I can feel free to send some pics to nablythe@btinternet.com and I will do my best to help you cheers Nigel
Hello GOSQI I have the same M300 Harrison Lathe. Perhaps you are willing to help me with specifications about the gears from Headstock and gearbox . Are they the same DP. A colchester bantam: 10 DP and 14,5 degree PA. I want to buy gear cutters to make some gears restoration from M 300 lathe. Thanks chris from Holland
Hello Chris sorry I can't help with the colchester parts.As far as the gear cutters are concerned they should be metric module gears so just measure the teeth width and that will give you the module you need. I.E. If the tooth is 3mm across you need a module 3 cutter and the cutters are marked 1 to 8 each one does a different number of teeth hope this helps. Cheers Nigel
Hello Nigel thanks for a quick answer. I don't have yet open the head-stock cover to measure. When it is a metric module gear it is easy for me to measure. I thought it is a Imperial lathe and it wiil be DP gears Thanks for this helps Cheers Chris
Hi again chris you may well be right and it is imperial all I did in my headstock was to check everything looked good and changed the oil, good luck with your tho I hope you get it all working they are good lathes and I am so glad I got mine. Nigel
@@fixitnige Did you bother putting that spring on, dosent look as if its needed? I'm going to have a look around some car shops tomorrow to see if i can find something. It's the cleaning that's the worst bit...
@@jimspencer3072 yes mate I did put the spring back I think it holds the arm still when the front plate is put back on or the arm would be floppy if that makes sense.
Hi Nigel. I have got the gearbox apart on my M300 at the moment, it looks like someone has been in to it before me. The selection was not right before I looked at it. Have you still got the cam alignment sequence you mentioned in a previous reply.
Hello chris I have looked everywhere for that but it must have been saved as a draft in my old emial client which I no longer use the only thing I can suggest is to ring harrison (600 group) and ask to speak to and engineer to help with the problem which is what I did. Good luck Nigel.
Hi Nigel. This video has helped me a great deal. Thank you. Just a quick question. When removing the gear selector box as I am about to, is there a gasket behind it or will it require gasket paste on refitting. Also is there a sump plug to drain prior to removal. Many Thanks. John
hello john there is a gasket but if your carefull it will be ok but you will need some good silycon sealer for the top of the box as there is now gasket at that point good luck
Hi Nige Im having right bother cutting metric threads on my imperial M300. It seems to be cutting imperial no matter what setting i use. Knowing i need to keep the half nut engaged throughout the metric performance it still cuts imperial/whitworth threads. Trying to get to the bottom of it. On my lathe above the 40/88/44 there is a number 95. On your metric model you have 96. What is this number for? Does this number over ride the 88 when doing imperial or metric threads. The manual says little about it. What have you discovered? Any info greatly appreciated. Regards John
Hello john sorry your having a few problems the 96 is the teeth on the rear sprocket as their are 4 sprockets for threading as you say you have to keep the half nuts engaged and run the motor forward and reverse.Looking at it to change to imperial I swap 88 and 44 the other way round but I have never needed it yet. Hope you get sorted Good Luck
Nige you are a star. You said it all with 4 sprockets for threading. The previous owner had spaced 95 sprocket out the way for some reason,so only 3 in mesh. No wonder it was not working right. I thought that was how it was since they were a decent engineering firm. I now have all 4 sprockets in mesh and its doing what it says on the tin. Thanks so much John
Hi Geoff I wiped it down with carb cleaner and thinners but it had been painted by the last owners so I did spend and long time with a wire wheel on my grinder to get off what I could. I repainted it cellulose primer and then sprayed with smooth silver hammerite but I may redo it with the original colours and paint. Cheers Nigel

tks: great usefull vid, I have the same m300 lathe but now want to go thread cutting and the gearbox doesn't work on all gears! so will get it out!
Hello esper glad the video helped you I hope you get your lathe working good.

Hi Nige which steering gaiter did you use for the Harrison ?
Hi It was just the small end from a universal one still working to this day :)

Hi John glad you got it sorted well done
cheers for now
Thanks Nigel
What did you use to decrease the lathe and what paint and undercoat type did you use ?
Hi Geoff I wiped it down with carb cleaner and thinners but it had been painted by the last owners so I did spend
and long time with a wire wheel on my grinder to get off what I could. I repainted it cellulose primer and then
sprayed with smooth silver hammerite but I may redo it with the original colours and paint.
