Dormer 108 Drill Grinder

Hi,

Does anyone here use a Dormer 108 Drill Grinder?

I have a machine that I have rebuilt, it works beautifully, expect the chisel angle is too high - all the other geometry is correct. I can’t see anything in the manual relating to adjusting the chisel angle - does anyone know how to do this please?

Thank you 🙂

The manual I have mentions setting the chisel angle. Happy to email a pdf copy to you if you private message me an email address to send it to. The manual I have has 22 pages.

Thank you Mike! PM sent.

Hi James, I have emailed the manual, I notice that it is for the Mk II machine which is what I have. I think the difference is mainly cosmetic between the two, if you have a Mkll then it’s happy days.

if anyone else needs a pdf manual for the Dormer 108 drill grinding machine then private message your email and I can send a copy.

Lucky man having one of these machines. I used one several months ago and would like to get obtain one for myself.

Thank you so much Mike, your manual has answered my question, problem solved! Mine is a Mk 1 machine, but a similar setup. In case anyone is looking for how to do this, slacken the bolt in front of the jaws:

Then you can turn the clamp head to adjust the chisel angle. Once you adjust this, there is a graduated scale that is hidden when the head is straight:

Colin, yes very fortunate. They do come up on eBay occasionally, I picked mine up from the home workshop site a few years ago. It needed quite a bit of work, but I will say there is nothing on there that can’t be made if needed, and there are no cams involved - but very pleased with the results 🙂

If anyone in Southern Ontario is interested in one of these, there's one for sale on Kijiji right now (for a grand).

Hi James, pleased the manual has cleared up the chisel point question. It looks like the Mkl and Mkll are very much the same machine so much of the manual will be relevant. It looks a nice tidy rebuild. You are probably aware that Midland Abrasives hold the remaining spare parts for the Dormer grinders, they are not cheap and could mostly be made or refurbished in a home workshop. The fingers for holding the drills would not be too difficult to make if the dimensions are available but I think I may stump up for the ones I don’t have and measure up before putting them to use.

There was one recently on Ebay, Trouble is the guy wanted £1000 which I could certainly not justify.

To Mike Poole

I have just picked up a 108 Mk2 and am currently stripping it down for refurbishment. I am having trouble removing the grinding wheel rear plate of the motor shaft. It is secured with four grub screws which I have removed. I am not sure if it unscrews of the shaft or just pulls off. I can get it to do neither. Have tried oil, heat and moderate force. Any ideas, any chance of a copy of your manual.

Hi Simon, I am happy to email the manual to you, if you use the message member with an email address that you would like me to send it to then that will keep your email out of the public area.

Could I respectfully request you send a copy of your manual to the vintagemachinery.org website? Everything they publish is freely available with no need to join or to log in and they seem to have a long-term plan for the continuity of the site.

A most excellent site. I have uploaded several things so they are publicly available. Another great resource is

The International Tool Archive
