Got a start turning the parts for the schottels today, long way to go with these LOL
I will be using M5 stainless steal for the shafts so i used a 4.5mm drill then an m5 reamer

A bit more done on the Shottels,

chipchase · « **Reply #52 on:** October 29, 2018, 09:45:57 pm »

I have had a few problems with my chest over the last few weeks so i have decided not to mess around with fibreglass for making the mould, Anth from Orion Mouldings is going to do the mould from my plug. I will post photos as soon as I have the first hull from the mould, i am sure the hull will be up to the normal high quality as alway

Machining looks superb, I really miss my lathe. Seeing this quality makes me seriously consider buying a new one.

I haven't done any turning for a while Brian my old lathe passed away LOL. When I decided to build the Stevns from scratch I new that a lathe would be needed so I had a look at the Warco Mini Lathe I just missed the one that was sold on here a few weeks ago pity it was a good buy. The new lathe has its limitations but it has been OK up to know.

The next part of the drive unit is the shottel rotation, the first photo shows the cog the way it was before cutting the small cog off.

chipchase · « **Reply #58 on:** October 30, 2018, 09:57:21 pm »

Then I turned two small brass inserts that will fit into the cogs, I made them a tight fit and will be using grub screws to secure them to the shottels

Brian60 · « **Reply #59 on:** October 31, 2018, 08:21:26 am »

Interesting answer to a problem with those inserts. You probably know that the gearwheels are made from a product called Delrin, like a type of nylon and impossible to bond to anything else - it has non stick properties similar to Teflon in frying pans. These fiendish far easters who supply them for a variety of purposes don't like to make life easy for modellers

They look good Jason I have built the same type for Bow thrusters

chipchase · « **Reply #65 on:** November 01, 2018, 10:14:33 pm »

Started on the bottom section of the Shottels, a few more photos showing the progress.

chipchase · « **Reply #66 on:** November 01, 2018, 10:39:07 pm »

quite pleased the way they are coming along starting to look like shottels, still a lot to do yet.

chipchase · « **Reply #67 on:** November 02, 2018, 04:27:38 pm »

Here is a photo of the latest update on the plug, this is the first half of the mould so far.

I am hoping to use Alloy tube Jason, I have ordered 80mm props from Prop Shop so i need 100mm diameter with hopefully a 8mm or 10mm wall thickness to be able to shape them on the lathe. I will need about 100mm in length to make the two korts, I did find a company that supplied the diameter that i needed but the wall thickness was only 3.2mm and at £43 for 100mm no thank you LOL

Thats the right diameter Jason but i don't have the a lathe big enough to drill it out thats the reason i need alloy tube

The lathe above should handle that size. Simply back out the jaws of the chuck completely, turn them around and insert backwards. That will allow you to hold your round bar sufficiently to machine it. I'm assuming you have a boring bar type cutting tool for machining internal bores?

chipchase · « **Reply #74 on:** November 04, 2018, 08:41:59 am »

I have boring tools Brian and the lathe comes with anti jaw chucks, but i would prefer buying the alloy in tube form instead of cutting all that metal out.
