I feel your pain! I'm not trying to make a watch, rather some extra runners for my Jacot tool. As you know, they need to be very precise. I sort of have the opposite problem you have; instead of reaming a hole I'm trying to turn a piece to precise radii as well as make a setting to hold the pivots. Knowing I'm not the only out there struggling is a great help. I know you'll succeed and because of that I will too! Keep it up!
Thanks so much, yeha I’m really starting to enjoy the struggle I know it sounds weird, but as long as we remain positive and search for answers, the result we are looking for come. I wish you all the success 😁😁👍🏼 let me know how you go with the runners
Hi Dean, I really think you need to make a floating reamer holder. This will allow the reamer to align and staying aligned with the head. Doing it the way you did can create trumpet shaped holes.... Always nice to watch your video's! Thanks, Donald
Hi Dean, you could take a look at Hemingway kits. They have the drawing on line, so you could take a look and make a mini version of it. I would say a cool project in itself 🤗 Regards, Donald
with making reamed holes smaller, try the biggest pre drill you can. spin faster, and feed faster. also you can buy reamers that are like . 0001" bigger or smaller than the nominal hole size.
Jigs will be helpful. Be mindful that glue adds a slight thickness and when not there will change dimensions. In manufacturing they use temperature controlled inspection rooms due to differences in expansion in materials Keep up the great work.
Hi John, thanks for watching and commenting. Yes I’ve been made aware recently at the lengths places go to for temperature control and it makes sense. Something I will be taking into serious consideration. Yes you’re right about the glue, another reason to add to the list of cons, and reason to move towards jigs.. P.S. Hugs will be helpful too, through the rough times. The notification had your unedited comment 👍🏼👍🏼😁😁
Stupid question again, but could the brass be flexing ever so slightly? Affecting the hole size as the reamer is pushed through? As theres no support behind it? Could you maybe put a sacrificial piece of aluminium flat bar stock behind the brass to give it a bit more guts just for peace of mind? I think youre doing great mate! And good job replicating your results to see where it went wrong. Looks awesome. I'd love to look into the horology stuff just never thought it was a thing in Australia but now I know you have.. Who knows? :)
Sam there is never a stupid question. I think there would be some flexing in the material, I’m not sure it makes a huge impact though. I think the hole size is actually quite precise. But it is a great suggestion for the additional support material. Maybe ifI didn’t have success i would’ve tried your suggestion. 👍🏼😁 it’s a bit harder here in Australia, but the internet has made the world a much smaller place
@@DeanDK as an Aussie myself... I wholeheartedly agree man! I see all the old swiss lathes and schaublins and mahos and bridgeports and then cry myself to sleep because theyre nowhere near as common here and seems knowledge isnt that common either. But glad youre on a platform where you get the chance to reach out to such talented individuals and creators :)
Well I did test the reamer choked up aswell on the 3rd hole I made where the shock proof setting had good friction, I could see movement on the reamer the . I have been thinking about after reading your comment, it is possible it moved slightly as the reamer caught something on the edge when I initially drove it into the hole.
Hi Sergiulik95, thanks for watching and commenting. The final watch case diameter in my head has been 43mm. But it may change during the making of the case. I hope it goes down in size slightly 😁👍🏼 thanks for asking
May I suggest going slower? Machinists use surface foot speed to calculate speeds and feeds in milling and drilling operations. when reaming a hole, the general rule is "half the speed, twice the feed." Once the reamer goes through the material, stop the spindle, and back the reamer out. Check the inside diameter, see what you get. Cheers...

Cool episode. There are floating reamer holders for gunsmiths (for chambering). Maybe that is something watchmakers can use too.
Thanks for watching and your feedback Robert 😁 interesting I will have a look into them 👍🏼👍🏼

Reamers I've bought are weirdly long. The explanation I heard was that the length helps with alignment, as you discovered.
Hmmm that’s interesting, thanks for that information, I’ve never heard that before
A win - lets get that balance bridge made for the last time.
Yessss! Very soon 😁
hang in there remember Edison made many attempts at the light bulb

Thanks Pete! Really appreciate the support 😁👍🏼

Thanks for the pro tip Christopher I appreciate it man. I will try fast speed and feed on pre drilled hole next time

So since there is visible movement of the reamer in the tailstock does it follow that the tailstock is off center?

Hi Dean what's the name of the lathe the cost and where did you get it thanks
Hi there, it’s a Cowells CW90. They display there prices on their website, try searching the lathe name or Cowells Small Machine Toklas 😁👍🏼
@@DeanDK thanks 😁 Lee
Hey dean, any idea about the final diameter of your watch? :D

sir，my engliht notgood i dont know you talking about, but you Video helped me a lot

Thanks so much for your support Mark, really appreciate it 😁😁
This is just not correct... and has nothing to do with reaming.
Thanks appreciate you watching and commenting. I’m unsure what you mean?
